US 7452202 B2Abstract
The invention concerns machinery for molding and assembling of at least two part objects and of plastics, e.g. two ball shells, which can be assembled to a hollow ball, as molding and assembly can take place in the same tool and continuously in the same work procedure. This can be realized by the two turnable middle parts and of the tool, respectively are supplied with the mold cavities and, where the assembling of the part objects and can take place, when the respective tool cavities meet during the rotation, at the same time as the closing of the mold. During the closing there can simultaneously be molded new part objects and in the opposite placed mold cavities and in the two turnable mold part and. If it is necessary in respect of the material or the design of the part objects, there can after the molding of the part objects be applied e.g. heat on the respective boundary surfaces, which shall shape the assembling. This can suitably be fit into the steps, which the turnable middle parts and run through. The part objects and can possibly as well as be assembly by a snap- or click function, which is a pure mechanical assembling.
This application is a divisional of U.S. application Ser. No. 10/415,281, filed on Apr. 28, 2003, now U.S. Pat. No. 7,081,222, which is a 371 of PCT/DK01/00699, filed on Oct. 23, 2001. This application claim benefit of foreign application DENMARK PA 2000 01605, filed on Oct. 26, 2005.
The procedure and the machinery according to the invention is intended to combine the above mentioned technology with the likewise known assembling technique, but here in one and the same tool, whereby there can be achieved large improvements of productivity.
On FIG. 1 is, seen from above, shown a section of a tool for the exercise of the procedure according to the invention. From the left is seen the stationary tool part 1 with a hot-runner furnished inlet 2, which directs the material further through the core 3. The tool is on the figure just opened after the first part object 4 is molded in the cavity 5 in the left of the two turnable middle parts 6 through the inlet 2 and the core 3. At the same time there is in the cavity 7 in the right of the two turnable middle parts 6′ molded another part object 8 with material from that with the inlet 2′ and the core 3′ furnished movable mold part 9. The two part objects 4 and 8 consist on the drawing of two uniform half ball shaped shells, that later is intended to be put together to a hollow ball. It will be noticed, that this assembling will be eased by the outermost boundary surfaces 10 and 11 on the respective part objects 4 and 8 exceed out from the turnable middle parts. This is accomplished by there are similar undercuts 12 and 12′ in respectively the stationary mold part 1 and the movable mold part 9: As it appears from the figure both the turnable middle parts 6 and 6′, which in principle has a square formed section, have got their corners removed, so that they require a lesser opening of the tool for being able to turn around. Finally shall be mentioned, that identical cross sections of the on the figure showed can be seen e.g. five places underneath the shown, if the tool is designed for producing in total six assembled objects pr. cycle.
In FIG. 2 is shown the same section, but where the two turnable middle parts 6 and 6′ both are turned 90 degrees in the direction of the respective arrows, whereby the two part objects 4 and 8 have reached the on the figure highest position. Here heat is applied on their respectively boundary surfaces 10 and 11 from the movable heat units 13. The tool is meanwhile preferably closed, and the two subsequent part objects 4′ and ‘8’ are just being molded through the two inlets 2 and 2′ and the cores 3 and 3′ in respectively the stationary mold part 1 and the movable mold part 9.
FIG. 3 shows the same section, where the two turnable middle parts 6 and 6′ both are turned additional 90 degrees in the direction of the respective arrows. The tool is here open, but moving towards closing, where the two part objects 4 and 8 will approach their two respective heated boundary surfaces 10 and 11 to each other before the welding together. The two following part objects 4′ and 8′ are now in their on the figure highest position, where they are receiving heat on their respective boundary surfaces 10′ and 11′ from the movable heat units 13. Finally the third set of part objects 4″ and 8″ are just being molded in the mold cavities 5″ and 7″, both the part objects are finished and ready for being turned away from their respective cores 3 and 3′.
On FIG. 4 the two turnable middle parts 6 and 6′ are turned another additional 90 degrees. Here the tool is closed, and the two part objects 4 and 8 now are melted together to the finished object, the hollow ball 4+8, which on the figure just is being ejected from the tool. It is noticed, that possible surplus material 14 suitably only exists on the inner side of the ball shell. The two following part objects 4′ and 8′ are here seen during the welding of their boundary surfaces 10′ and 11′ in the closed mold, and the third set of part objects 4″ and 8″ is getting their respective boundary surfaces 10″ and 11″ heated by the movable heating units 13. Finally has the fourth set of part objects 4′″ and 8′″ just been molded at their respective cores 3 and 3′.
Hereby the first sequence of the two turnable middle parts 6 and 6′ is terminated. By the next turning of 90 degrees a new molding- and assembling cycle is started, as the first, where all four sides of each of the two turnable middle parts 6 and 6′ are in full function. Hereafter a continuous production of part objects and the assembling hereof can continue after the same principles.
