Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, and in particular relates to an eight-cavity nylon sleeve injection mold. Background Art

[0002] An injection mold is a precision tool used to produce plastic products. It consists of two or more metal molds that fit together, usually made of steel or alloy to ensure long-term stable operation under high temperature and high pressure. The main function of an injection mold is to inject molten plastic material into the mold cavity. After cooling and solidification, the mold opens to obtain a plastic product of the desired shape.

[0003] In the production process of nylon sleeves, the number of cavities in the mold is crucial to production efficiency and cost control. At present, the number of cavities in nylon sleeve molds is relatively small, which leads to a long production cycle of a single mold during the injection molding production process, thereby reducing the overall production efficiency. At the same time, due to the insufficient number of cavities in the mold, the mold may need to be replaced frequently during the production process, increasing operating costs and time consumption. Utility Model Content
