Abstract:
1. A resin molding device which molds a resin tube from a molten resin, comprising: a heating cylinder; a screw disposed in the heating cylinder; a hopper; and a storage tank storing a resin material, and configured to transport the resin material to the hopper through a transport line, wherein all parts of the storage tank, the hopper, and the heating cylinder, which are associated with the resin material, including the transport line of the resin material, are formed into a sealed-type structure under a N wherein the resin molding device comprises a jig which defines inner and outer diameters of the resin tub; wherein the heating cylinder is formed with a molten resin extruding portion at an end portion thereof, wherein the resin molding device further comprises a tube molding portion connected to the molten resin extruding portion through an insulating material to define an outer diameter of the resin tube, and a spindle member inserted into the tube molding portion and extending to a position near an exit of the tube molding portion to define an inner diameter of the resin tube, the tube molding portion and the spindle member collectively serving as the jig, wherein a tubular casing is attached to an end portion of the tube molding portion to cover a periphery of the resin tube coming out from the tube molding portion, a N wherein the tube molding portion comprises a cylinder member wherein the tubular casing is connected, and a cooling portion is provided around the cylinder member.
