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
The present invention relates to a kind of switch injection molding mould, be exactly a kind of injection forming mold.
Background technology
nullThe parts of the materials such as plastics carry out injection mo(u)lding processing operation at present is，The mobility of liquid material directly shaping efficiency and Forming Quality to workpiece plays decisive role，Because of in order to improve liquid material mobility in a mold，Generally require and mould heating arrangements is set in injection forming mold for mould is heated，At present in actual use，The mode of heating of injection forming mold is circulated in order to realize the effect to mould heating at mould inside by pipeline with high-temperature water or high temperature oil often，This way，Although reaching to improve mold temperature，Improve the purpose of material flow，But due to often relatively low as the water of medium or the heating-up temperature of oil，Therefore seriously limit mould heating properties and affect mobility and the processability of raw material，Simultaneously，Mould is in the process used，Separately require over mold base to be transferred on injection-moulding device，Therefore the use motility and the efficiency that cause mould are relatively low，For this present situation，In the urgent need to developing the injection forming mold of a kind of invention，To meet the needs that actual production uses.
Summary of the invention
For the deficiency existed in prior art, the present invention provides a kind of injection forming mold, this inventive structure is simple, flexible and convenient to use, can effectively improve efficiency and the quality of injection mold heating on the one hand, thus helping and the mobility and the surface forming quality that improve and improve injection raw material, the heating arrangement of injection mold can be effectively simplified on the other hand, improve injection mold and use motility and work efficiency.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of injection forming mold, including front template, front cavity, rear pattern plate and rear cavity, wherein front cavity is embedded in front template, rear cavity is embedded in rear pattern plate, front template and rear pattern plate and front cavity and rear cavity all offset and constitute airtight molding cavity, set heat dam between front cavity and front template and between rear cavity and rear pattern plate to isolate, steam heat cycles pipe and water route homoiothermic circulation pipe is set in front template, and described steam heat cycles pipe and water route homoiothermic circulation pipe are all distributed around front cavity and set vapor interface and water circulation interface at front template side surface, cooling water circulation pipe is set in rear pattern plate, cooling water circulation pipe ring sets cooling water water inlet around rear cavity distribution and at rear pattern plate side surface.
Further, described heat dam width is not more than 3 millimeters.
Further, described heat dam position between front template, rear pattern plate outer surface and steam heat cycles pipe, water route homoiothermic circulation pipe and cooling water circulation pipe
Present configuration is simple, flexible and convenient to use, can effectively improve efficiency and the quality of injection mold heating on the one hand, thus helping and the mobility and the surface forming quality that improve and improve injection raw material, the heating arrangement of injection mold can be effectively simplified on the other hand, improve injection mold and use motility and work efficiency.
