Die structure for preventing edge of thermoplastic plastic part with flange plate at end head from easily generating flash

According to the mold structure, an upper pressing block and a lower pressing block are additionally arranged on the upper surface and the lower surface of a combined sliding block respectively, during mold opening and closing, an upper mold plate makes direct contact with the upper pressing block, and a push plate makes direct contact with the lower pressing block; after a forming cavity is formed by the combined sliding block, the upper die block and the push plate, the combined die block does not directly rub with the upper die plate and the push plate to cause abrasion, and the periphery of a plastic part is not prone to flash in the molding process. In addition, the combined module is attached to the upper pressing block and the lower pressing block without zero clearance, so that the formed cavity has an exhaust function. 本发明公开了一种端头带法兰盘热塑性塑料件边缘不易出飞边的模具结构，该模具结构在组合滑块上表面和下表面分别增加上压块、下压块，开合模时，上模板直接与上压块接触，推板直接与下压块接触，组合滑块、上模块和推板构成的成型型腔后组合模块不会与上模板、推板直接存在摩擦而造成磨损，塑件在塑型过程中周边不易有飞边；此外，组合模块与上、下压块之间的贴合由于达不到零间隙，使成型的型腔具
