Abstract

The invention discloses an excess injection correction device applied to an injection mold, and belongs to the field of injection equipment. The excess injection correction device applied to the injection mold can correct the shot capacity by controlling the elongation of a hydraulic cylinder telescopic rod in a pressure injection device during trial production, and after one correction, the shotcapacity of the pressure injection device is limited by marking the hydraulic cylinder telescopic rod in the pressure injection device. Therefore, the shot capacity of subsequent injection operation is basically kept consistent, the correction effect of the last shot capacity is achieved, the correction times can be reduced on the premise of maintaining the injection quality, the production process of the injection operation can be optimized, time of single injection can be shortened, injection production efficiency can be improved, the effect of single correction can also be highlighted, andthe correction system is an important supplement to an excess injection correction system.

Description

technical field [0001] The invention relates to the field of injection molding equipment, in particular to an over-injection correcting device applied to an injection mold. Background technique [0002] The product production process refers to the whole process from raw material input to finished product production, usually including process, inspection process, transportation process, waiting process and natural process. The process is the most basic part of the production process. For the mechanical manufacturing process, it can generally be divided into three stages: blank manufacturing, parts processing and product assembly. [0003] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machin...
