Description: MOBILE TOOLING BASE TECHNICAL FIELD OF THE INVENTION [0001] The present invention generally relates to a tooling base for supporting an assembled tooling stack for a blow-molding machine and allowing the tooling stack, while mounted to the tooling base, to be readily moved and easily loaded into the blow-molding machine. BACKGROUND [0002] Blow-molding machines typically incorporate a number of different tooling components that cooperate during the blow-molding process to produce the finished blow-molded product. The various components are stacked on top of each other within the molding station of the blow-molding machine. These components are made from steel or cast iron typically, and are therefore heavy and cumbersome to move and assemble into the machine. When the tooling within the blow-molding machine is to be changed, the stack of tooling components must be disassembled and removed from the machine piece by piece, thereby making the change-over time for the blow- molding machine lengthy. [0003] Therefore, there is a need in the industry for an improved method of loading and unloading the tooling for a blow-molding machine to make a change-over of the blow-molding machine easier and less time consuming. SUMMARY OF THE INVENTION [0004] In accordance with an aspect of the present invention, a quick change tooling base for storing and moving a tooling stack into a blow-molding machine includes a sub-base for supporting the tooling stack for a blow-molding machine. The sub-base includes features adapted to attach the tooling to the sub-base as well as features adapted to attach the sub-base to the blow-molding machine. A plurality of channels are further formed within the bottom surface of the sub-base and are adapted to connect to a supply of pressurized air. Upon pressurization when the sub- base is resting upon a support surface, the sub-base is forced to rise above the surface and is thereafter supported upon a layer of pressurized air, allowing the tooling base, with the tooling stack thereon, to be readily moved over the surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0011]The following description of the preferred embodiment of the invention is not intended to limit the scope of the invention to this preferred embodiment, but rather to enable any person skilled in the art to make and use the invention. [0012] Referring to the figures, a quick change tooling base for storing and moving tooling into a blow-molding machine is shown generally at 10. Referring to FIGS. 1 , 3A, 3B and 3C, the tooling base 10 includes a sub-base 12 having a top surface 14, a bottom surface 16, and opposing first 18 and second 20 ends. The top surface 14 is adapted to support a tooling stack 22 (hereafter referred to as "tooling") thereon. A first support 24 and a second support 26 extend upward from the top surface 14 of the sub-base 12. The first and second supports 24, 26 are spaced apart from each other with the first support 24 being located toward the first end 18 and the second support 26 being located toward the second end 20. The first and second supports 24, 26 include features formed therein to secure the tooling 22 to the sub- base 12 and to secure the sub-base 12 to the blow-molding machine. [0013] In the preferred embodiment, the sub-base 12 includes a plurality of first threaded bores 28 formed within the top surface 14. The first threaded bores 28 are adapted to receive a threaded fastener which will extend through the tooling 22, thread into the first threaded bores 28, and attach the tooling 22 to the sub-base 12. The sub- base 12 further includes a plurality of first through bores 30 formed within the top surface 14. The first through bores 30 are adapted to receive a threaded fastener which will thread into a threaded bore on the blow-molding machine to attach the tooling base 10 to the blow-molding machine. [0014] Referring to FIG. 2A and 2B, the tooling base 10 further includes a tooling carrier 32 which mounts to the sub-base 12 to further secure the tooling 22 to the sub-base 12. The tooling carrier 32 includes a top plate 34 with a top surface 36 and a bottom surface 38. A first leg 40 and a second leg 42 extend downward from the ends and bottom surface 38 of the top plate 34 to engage the sub-base 12. [0015] The top plate 34 of the tooling carrier 32 further includes portions defining at least one aperture 44 extending from the top surface 36 of said top plate 34. The aperture 44 is adapted for engagement with a device to lift and transport the tooling base 10 and the tooling 22 mounted therein. In the preferred embodiment, the tooling carrier 32 includes three apertures 44 which are adapted to receive a fork of a hi-lo or lift truck vehicle to allow the tooling base 10 and the tooling 22 to be lifted and transported. It is to be understood, that the aperture 44 could be adapted to engaged any type of vehicle or device such as a hoist or crane that would be used to lift and transport the tooling base 10. [0016]The tooling carrier 32 further includes a plurality of features adapted to attach the tooling carrier 32 to the tooling 22. In the preferred embodiment, the tooling carrier 32 includes a plurality of second through bores 46 adapted to receive threaded fasteners that thread into threaded bores within the tooling 22 to attach the tooling carrier 32 to the tooling 22. [0017]The sub-base 12 and the tooling carrier 32 each include a plurality of features adapted to attach the tooling carrier 32 to the sub-base 12. In the preferred embodiment, the sub-base 12 includes a plurality of second threaded bores 48, and said tooling carrier 32 includes a corresponding plurality of third through bores 50. Each of the second threaded bores 48 and the corresponding third through bores 50 are adapted to receive a threaded fastener, whereby the threaded fasteners extend through the third through bores 50 within the tooling carrier 32 and thread into the second threaded bores 48 within the sub-base 12 to attach the tooling carrier 32 to the sub-base 12. [0018] The sub-base 12 includes at least one spacer disposed between each of the first and second supports 24, 26 of the sub-base 12 and the tooling 22. In the preferred embodiment, at least one block spacer 52 and one adapter spacer 54 is disposed between the tooling 22 and the supports 24, 26 on each end of the sub-base 12. Referring to FIG. 2A, two block spacers 52 are shown, however it is to be understood, that any appropriate number of block spacers 52 could be used depending on the stack height of the tooling 22 and the height of the supports 24, 26 on the sub-base 12. [0019] In the preferred embodiment, the first and second supports 24, 26 each include a plurality of third threaded bores 56. As shown in the FIG. 1, each of the supports 24, 26 in the preferred embodiment include three such threaded bores 56. Each of the block spacers 52 and adapter spacers 54 used includes a corresponding plurality of fourth through bores 58. Each of the fourth through bores 58 and each of the third threaded bores 56 are adapted to receive a threaded fastener, whereby the threaded fastener extends through the fourth through bores 58 of the block spacers 52 and adapter spacers 54 and engages the third threaded bores 56 of the supports 24, 26 to secure the block spacers 52 and the adapter spacers 54 to the supports 24, 26. [0020] Likewise, the adapter spacers 54 include a plurality of fourth threaded bores 60, wherein the fourth threaded bores 60 of each of the adapter spacers 54 are adapted to receive a threaded fastener whereby a threaded fastener is inserted into a through bore within the tooling 22 and threaded into the fourth threaded bores 60 to secure the tooling 22 to the adapter spacers 54 and thereby securing the tooling 22 to the first and second supports 24, 26. [0021]The sub-base 12 includes at least one channel 62, formed within the bottom surface 16, that is adapted for connecting to a supply of pressurized air. When the tooling base 10 is resting upon a surface and pressurized air is supplied to the channels 62, the tooling base 10 is forced to rise above the surface and is supported upon a layer of pressurized air, thereby allowing the tooling base 10 to be readily moved over the surface upon which the tooling base 10 was resting. The tooling base 10 with the tooling 22 mounted thereon is too heavy for manual lifting and by floating the tool base 10 on a layer of air, the tooling base 10 can be moved easily over the surface and put into position within the blow-molding machine. [0022] The sub base 12 includes a side wall 64 and at least one air passage 66 extending from the side wall 64 to the channel 62. Referring to the figures, the preferred embodiment includes three parallel channels 62 formed within the bottom surface 16 of the sub-base 12. The two outer channels 62a are joined by an air passage 66a which extends outward to the side wall 64 of the sub-base 12 and the inner channel 62b is joined with one of the outer channels 62a by another air passage 66b which extends out to the same side wall 64 as the first air passage 66a. Each of the air passages 66a, 66b includes a threaded portion 68 adjacent to the side wall 64 to allow threaded engagement with a supply of pressurized air. It is to be understood, that the air passages 66a, 66b could be connected to a supply of pressurized air by other suitable means. [0023JThe sub-base 12 further includes a plurality of alignment bores 70. In the preferred embodiment, there are two such alignment bores 70, one at each end 18, 20 of the sub-base 12. Each of the alignment bores 70 is adapted to receive a dowel that will extend downward through the sub-base 12 and into a corresponding aperture within the blow-molding machine. The apertures are adapted to receive the dowels to align the tooling base 10 within the blow-molding machine. Once the sub-base 12 has been aligned, and the dowels are placed, the pressurized air can be removed, and the sub-base 12 will settle into place within the blow-molding machine. [0024] In the preferred embodiment, the tooling base 10 is designed to accommodate the tooling 22 for the blow-molding machine where the tooling 22 includes an adaptor plate 72 that is designed to allow the tooling 22 to be mounted within the machine. Although not an actual tooling component, the adaptor plate 72 is necessary to allow the particular tooling stack to be mounted to the blow-molding machine. The blow molding machine includes an over-sized opening which is necessary to allow the tooling stack 22 to be fed into the blow-molding machine. The purpose of this over-sized opening is two-fold. First, the over-sized opening will accommodate the tooling stack as the tooling stack 22 is fed into the blow-molding machine, and secondly, the over-sized opening can accommodate various types of tooling which will have different sizes. However, the large over-sized opening is too large to directly mount the tooling 22 to the edges, so an adapter plate 72, which is unique to the particular tooling stack 22, is included within the tooling stack 22 to allow the tooling stack 22 to be mounted to the blow-molding machine at the edges of the over-sized opening. Accordingly, the overall design of the tooling base 10 is such that the tooling base 10 will accommodate the tooling 22 along with the adaptor plate 72 incorporated therein. [0025] A method of using the tooling base 10 of the present invention to transport and load tooling 22 into a blow-molding machine includes the following steps. First, the tooling 22 for the blow-molding machine is secured to the tooling base 10. The tooling components are individually stacked to the sub-base 12 and held there by threaded fasteners that engage the sub-base 12. After a portion of the tooling 22 has been placed to the sub-base 12, the spacers 52, 54 are placed to the supports 24, 26 and the tooling 22 is further secured to the sub-base 12 by threaded fasteners that extend through the tooling 22 and the spacers 52, 54, and engage the supports 24, 26. [0026]The remaining tooling 22 is placed to the stack, and the tooling carrier 32 is placed onto the sub-base 12. The top plate 34 of the tooling carrier 32 is secured to the top of the tooling 22 stack by threaded fasteners which extend through the top plate 34 and engage the tooling 22. The first and second legs 40, 42 of the tooling carrier 32 are secured to the sub-base 12 by threaded fasteners that extend through the through bores within the legs 40, 42 and engage the sub-base 12. [0027]The tooling base 10, with the tooling 22 secured thereon is then transported to a staging surface which is adjacent to the blow-molding machine. The tooling base 10 is transported by using a device such a fork lift to engage the apertures 44 on the top plate 34 and lifting the tooling base 10 with the tooling 22 thereon. When the tooling base 10 is placed to the staging area, the tooling carrier 32 is removed from the tooling 22 and the sub-base 12. [0028] The sub-base 12 is then moved from the staging surface into the blow- molding machine, where the sub-base 12 is aligned and secured within the blow- molding machine. The sub-base 12 is moved by supplying pressurized air to the channels 62a, 62b, whereby the sub-base 12 is forced to rise above the staging surface, supported upon a layer of pressurized air. With the sub-base 12 supported above the staging surface on a layer of air, the sub-base 12 is then easily pushed into the blow-molding machine. While the sub-base 12 is still supported by the pressurized air, the alignment bores 70 within the sub-base 12 are aligned with corresponding apertures in the blow-molding machine. When properly aligned, dowels are placed to the apertures and alignment bores 70 to locate the sub-base 12 in the correct position and the pressurized air is turned off or removed. [0029] Once the sub-base 12 is settled within the blow-molding machine, the sub-base 12 itself is secured within the blow-molding machine with threaded fasteners that extend through the sub-base 12 and engage the blow-molding machine. [0030]The foregoing discussion discloses and describes one preferred embodiment of the invention. One skilled in the art will readily recognize from such discussion, and from the accompanying drawings and claims, that changes and modifications can be made to the invention without departing from the true spirit and fair scope of the invention as defined in the following claims. The invention has been described in an illustrative manner, and it is to be understood that the terminology that has been used is intended to be in the nature of words of description rather than of limitation.
