Injection molding die

Abstract

The invention relates to an injection molding die. The injection molding die comprises a front die plate, a front die core, a rear die plate and a rear die core. The front die core is embedded in the front die plate. The rear die core is embedded in the rear die plate. The front die plate abuts against the rear die plate and the front die core abuts against the rear die core, so that an airtight forming cavity is formed. A heat insulating groove is formed between the front die core and the front die plate so as to isolate the front die core from the front die plate, and a heat insulating groove is formed between the rear die core and the rear die plate so as to isolate the rear die core from the rear die plate. A steam heating circulating pipe and a water circuit temperature regulation circuiting pipe are arranged in the front die plate and both surround the front die core, and a steam port and a water circuiting port are formed in the lateral surface of the front die plate. A cooling water circuiting pipe is arranged in the rear die plate and surrounds the rear die core, and a cooling water receiving port is formed in the lateral surface of the rear die plate. According to the injection molding die, on one hand, the heating efficiency and quality of the injection molding die can be effectively improved; and on the other hand, the heating structure of the injection molding die can be effectively simplified, and the use flexibility and working efficiency of the injection molding die are improved.

Description

technical field [0001] The invention relates to an open and plastic mold, in particular to an injection molding mold. Background technique [0002] At present, the injection molding process of parts made of plastic and other materials is that the fluidity of the liquid raw material directly plays a decisive role in the molding efficiency and quality of the workpiece, because in order to improve the fluidity of the liquid raw material in the mold, it is often necessary to The mold heating mechanism is set in the molding mold to heat the mold. In actual use, the heating method of the injection molding mold is often to use high-temperature water or high-temperature oil to circulate inside the mold through pipelines to achieve the effect of heating the mold. Although this approach achieves the purpose of increasing the mold temperature and improving the fluidity of the raw material, because the heating temperature of water or oil as the medium is often relatively low, it severel...

[0002] At present, the injection molding process of parts made of plastic and other materials is that the fluidity of the liquid raw material directly plays a decisive role in the molding efficiency and quality of the workpiece, because in order to improve the fluidity of the liquid raw material in the mold, it is often necessary to The mold heating mechanism is set in the molding mold to heat the mold. In actual use, the heating method of the injection molding mold is often to use high-temperature water or high-temperature oil to circulate inside the mold through pipelines to achieve the effect of heating the mold. Although this approach achieves the purpose of increasing the mold temperature and improving the fluidity of the raw material, because the heating temperature of water or oil as the medium is often relatively low, it severely limits the heating performance of the mold and affects the fluidity and molding performance of the raw material. At the same time, during the use of the mold, it needs to be transferred to the injection molding equipment through the mold base, so the flexibility and efficiency of the forming mold are relatively low. In view of this situation, it is urgent to develop an inventive Injection molding molds to meet the needs of actual production use
