模具排气系统设计探讨

Discussion on the Design of Mold Exhaust System

由于模具排气系统的不良,往往会造成模具在试模和生产过程中,出现塑件外观缺陷。为了满足客户对塑件高质量的要求,需要考虑模具排气系统的合理性。通过注射成型的不断尝试,验证了模具排气系充的重要性,找到了模具排气系统设计中的一些经验参.考值,可供模具技术人员借鉴。

Due to the poor exhaust system of the mold, the appearance defects of the product often appear in the process of mold test and production. In order to meet customers’ requirements for high quality plastic products, it is necessary to consider the rationality of the mold exhaust system. Through the continuous attempt of injection molding production, the importance of mold exhaust system filling is verified, and some experience reference values in the design of mold exhaust system are found, which can be used for reference by mold technicians.
