Abstract

The invention discloses an injection mold for a plastic prefabricated part. The injection mold comprises a lower mold base, a guide sleeve, a guide rod, an upper mold base, a sprue bush, an upper supporting plate, a mold core base plate, an upper mold core, a lower supporting plate, a lower mold core, a push rod and a push plate; the lower mold base is fixedly connected with the guide sleeve; the guide sleeve is in sliding connection with the guide rod; the guide rod is fixedly connected with the upper mold base; the upper mold base is fixedly connected with the sprue bush; the upper mold base is fixedly connected with the upper supporting plate; and the upper supporting plate is fixedly connected with a fixed mold plate. According to the injection mold, the prefabricated part can be fixed fast through the mold, and the product quality is improved by hiding weld marks; the prefabricated part is fixed to a female mold through a linkage type clamping device, the steps of heating and pasting are omitted, and the fixing effect is stable; and during mold assembly, one part of the clamping device keeps fixing the prefabricated part, the other part is folded, the clamping device does not influence plastic part forming, and the other part of the clamping device is pushed under the injection pressure during injection molding.

Description

technical field [0001] The invention relates to the technical field of plastic molds, in particular to an injection mold for plastic prefabricated parts. Background technique [0002] In-mold insert injection molding decoration technology is to put the printed and formed decorative sheet into the injection mold, and then inject the resin on the back of the formed sheet, so that the resin and the sheet are integrated into one solidified molding technology, and now The mold used by the technology cannot quickly and effectively fix the prefabricated part, resulting in a decline in product yield. At the same time, this technology is prone to weld lines between the preform and the newly formed part, and the weld lines are exposed, making it difficult to guarantee product quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an injection mold for plastic prefabricated parts, which solves the problem that the mold ca...
