Technical Field

[0001] The utility model relates to the field of injection molds, in particular to an injection mold for plastic products. Background Art

[0002] Plastic injection molds are tools used for injection molding of plastic products, usually consisting of two or more molds. During the injection molding process, plastic particles are heated and melted and then injected into the mold cavity. After cooling, the desired plastic product is formed. Injection molds play a vital role in the production of plastic products, directly affecting the quality, production efficiency and production cost of the product.

[0003] However, traditional plastic product injection molds are usually designed and manufactured for products of specific shapes.
