Description

Technical Field

[0001] The present application relates to the field of injection molds, and in particular to an injection mold for an electric vehicle battery box housing. Background Art

[0002] An injection mold is a manufacturing tool used in the plastic injection molding process. It consists of a high-precision mold and mold support, and is primarily used to produce plastic products of various shapes and sizes. Injection molds typically consist of two main parts: a front mold (punch) and a back mold (die). The injection molding process involves injecting molten plastic material into the mold under high pressure, where it cools and solidifies to form the desired plastic product.

[0003] To increase the strength of existing electric vehicle battery housings, reinforcing ribs are usually provided on the outer sides, which makes it difficult to demould during injection molding and is relatively inconvenient. Utility Model Content
