In-mold cutting injection mold and use method thereof

Abstract

The invention provides an in-mold cutting injection mold and a use method thereof. The in-mold cutting injection mold comprises a fixed mold and a movable mold, wherein the movable mold and the fixed mold are connected to form a mold cavity. The in-mold cutting injection mold further comprises a drainage opening plate, wherein the drainage opening plate is arranged on the movable mold, and a drainage opening communicated with the mold cavity is formed in the drainage opening plate; an ejection mechanism which is movably arranged on the movable mold; and a cutting tool, wherein one end of the cutting tool is connected with the ejection mechanism, and the other end of the cutting tool is located at the connecting position of the drainage opening plate and the mold cavity, and the cutting tool is driven by the ejection mechanism to cut the drainage opening material at the connecting position of the drainage opening plate and the mold cavity. Through the arrangement of the cutting tool and the driving of the ejection mechanism, the drainage opening material connected with the injection molding product is automatically cut off in the mold, so that the operation difficulty of manual cutting off is eliminated, and the production efficiency is improved; and meanwhile, the drainage opening material is cut off when the injection molding product is not completely cooled and hardened, and breaking marks on the injection molding product are eliminated.

Description

technical field [0001] The invention relates to the technical field of injection molding production, in particular to an in-mold cutting injection mold and a use method thereof. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. The injection molding process can be roughly divided into the following six stages: mold closing, injection, pressure holding, cooling, mold opening, and product removal. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex shape products and other molding processing fields. [0003] Injection molding is inseparable from the injection mold. Usually, there is a nozzle on the injection mold. The inject...
