Abstract

The invention discloses a thermal overload relay base injection mold. The thermal overload relay base injection mold comprises a fixed mold thermal insulation plate, a fixed mold bottom plate, a fixed mold plate, a movable mold plate, a movable mold bottom plate, a movable mold thermal insulation plate and a mold leg strip which are sequentially arranged from top to bottom. The fixed mold bottom plate is fixedly connected with the fixed mold plate. A positioning ring is arranged in the middle of the fixed mold thermal insulation plate and is fixedly connected with the fixed mold thermal insulation plate. A sprue bush is arranged in the positioning ring. First forming inserts are arranged at the two ends of the fixed mold plate. A second forming insert is arranged below the sprue bush. The thermal overload relay base injection mold is made of thermoset phenolic plastic through injection molding, the forming temperature is high, manufactured products are good in quality and high in machining accuracy, and mold opening is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of mold equipment, in particular to an injection mold for a base of a thermal overload relay. Background technique [0002] Injection molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics; according to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot compression molds (compression molds), injection molds, etc. Among them, the hot pressing mold can be divided into three types: overflow type, semi-overflow type and non-overflow type according to the overflow method, and the injection mold can be divided into two types: cold runner mold and hot runner mold according to the pouring system; according to the loading and unloading method It can be divided into two types: mobile and fixed. [0003] Although the structure of the mold may vary due to the variety and performance of the p...
