AI Technical Summary
Technical Problem
In the prior art, the cooling channel of the injection mold for battery plastic parts has a small cooling range, which leads to uneven cooling, affects the quality of the finished product and may cause warping. In addition, thin-walled parts are prone to breakage during ejection.
Method used
The ring-shaped cooling box and guide rod structure are adopted to increase the cooling range and improve the cooling efficiency. At the same time, a buffer mechanism is installed at the outer end of the ejector pin to reduce impact force and protect the finished product.
Benefits of technology
This resulted in more uniform cooling, reduced the risk of warping and breakage of finished products, and improved product quality.

Abstract
The utility model discloses an injection mold for plastic parts of batteries, and belongs to the field of injection molds. A battery plastic part injection mold comprises a movable mold and a fixed mold, the fixed mold is installed on a fixed mold frame bottom plate, the movable mold is installed on a bearing plate, the bearing plate is connected with a movable mold frame bottom plate through a partition block, a male mold is installed on the movable mold, a female mold is installed on the fixed mold, and a cooling box installed in a clamping groove in the fixed mold is arranged on the outer side of the female mold. The two ends of the cooling box are connected with water inlet pipes through first flow dividing boxes, the top and the bottom of the cooling box are connected with water drainage pipes through second flow dividing boxes, and a plurality of cooling water pipes are evenly installed on the outer side of the cooling box. Through the annular cooling box installed on the fixed mold and the second guide rod arranged on the movable mold, rapid cooling can be conducted through the cooling box after mold closing, the cooling range can be enlarged through the cooling box, the cooling efficiency of the mold is improved, and cooling is more uniform.
