Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with an anti-dislocation function. Background Art

[0002] Injection molding is a common plastic processing method, also known as injection molding or injection molding. It uses an injection machine to inject molten plastic material into a mold, and after cooling and solidification, it forms the desired plastic product. The injection molding process is usually used to produce large quantities of plastic products. It has the advantages of short production cycle, low cost, and stable product quality. Injection molds are tools used to produce plastic products. They usually consist of at least two parts: the injection part and the molding part. Injection molds play a vital role in the production of plastic products. Their design and manufacturing quality directly affect the molding quality and production efficiency of the product.

[0003] At present, when using injection molds, the upper mold is usually aligned with the lower mold, followed by compression molding, and then injection molding. This method will cause misalignment between the upper mold and the lower mold during processing, which will lead to the upper and lower mold cavities not completely corresponding to each other. The product is inconsistent with the expected shape after molding, which reduces the production quality. In addition, adhesion will occur at the connection between the upper mold and the lower mold, making it difficult to open and close the mold, requiring more time and labor to clean and maintain the mold, thereby reducing production efficiency.
