Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an injection molding mold for household appliance accessories. Background Art

[0002] An injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and molten plastic into a mold cavity under high pressure by an injection molding machine, and obtaining a molded product after cooling and solidification. Injection molds are often used in the production of home appliance accessories.

[0003] Patent application number CN202221867856.5 discloses an injection mold for household appliance accessories, including a male mold and a female mold. The male mold and the female mold are arranged opposite to each other, and one side of the male mold is convex relative to the female mold, and one side of the female mold is concave relative to the male mold. After the mold is closed, the convex part and the concave part cooperate to form a mold cavity.

[0004] When the above-mentioned injection mold is in use, manual force is required to separate the male mold from the female mold, which is troublesome to operate. In addition, there will be an instantaneous force during the mold separation process, which may cause the injection molded accessories to fall off instantly, causing damage to the accessories.
