Problems solved by technology

[0005] In order to solve the above-mentioned problems, the object of the present invention is to provide a GCP auxiliary injection molding machine that can improve the surface quality of plastic parts. It moves the airway outward through the external diverter valve and pipeline, and on the one hand avoids internal complex airways. On the other hand, the diverter valve and pipeline that can be used repeatedly can greatly save the cost of mold production and have good applicability

Abstract

The invention provides a GCP assistant injection molding machine capable of improving surface quality of a plastic product. The machine is characterized in that an air channel is transferred outwardsthrough an external flow division valve and a pipeline. Therefore, the problems of blockage and non-uniform air pressure caused by internal complex air channels can be avoided; and moreover, the flowdivision valve and the pipeline can be recycled, so that the die manufacturing cost can be extremely saved; and the adaptability is high.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to a GCP auxiliary injection molding machine capable of improving the surface quality of plastic parts. Background technique [0002] Gas counter pressure (GCP) technology is a dynamic gas pressure control technology, and its control parameters include GCP pressure and GCP action time. In recent years, GCP technology has been successfully applied to the injection molding process, forming a GCP-assisted injection molding process. According to different injection molding processes, the GCP-assisted injection molding process can be divided into GCP-assisted conventional injection molding (CIM) process, GCP-assisted chemical foaming injection molding process and GCP-assisted microcellular foam injection molding (Microcellular injection molding, MIM) process, The molds used in the above three processes are GCP-assisted CIM molds, GCP-assisted chemical foaming injection molds and GCP-assis...
