Injection molds are divided into thermosetting plastic molds according to the characteristics of the injection mold.Two types of thermoplastic molds; according to the type of process zone is divided into a shaping mold, blow mold, cast mold, thermoforming mold, hot press mold (plastic mold), injection mold, etc., wherein the thermal mold is in the profile. Divided into overflow, epitogenous, no three kinds,Injection moldThere are two types of cold flow channels and heat flow modes in the casting system; two types can be divided into mobile, fixed-form.
The structure of the mold although due to plastic varieties and performance,plastic productsThe shapes and structures and the type of injection may be different, but the basic structure is consistent. The mold is mainly composed of casting systems, temperature control systems, molded parts, and structural parts. The casting system and the molded part are direct contact with the plastic, and varies with plastics and articles, the most complex and maximum change in molding, and requires the highest processing of finish and the highest precision.The injection mold is composed of two parts: moving mold and the mold, and the moving mold is mounted on the moving template of the injection molding machine, and the mold is mounted on the fixed template of the injection molding machine. Moving molding in injection molding constitutes a casting system and a cavity, mold opening, and mold separation to remove plastic products. In order to reduce heavy mold design and manufacturing workload, most injection molds have adopted standard models.
