Description

Technical Field

[0001] The utility model relates to the technical field of injection molding molds, in particular to a slider quick demoulding mechanism. Background Art

[0002] Injection molding is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, shape and size can be set according to requirements, and the product size is precise. It can form parts with complex shapes. The key component in injection molding is the injection mold.

[0003] The injection mold consists of a concave mold and a convex mold. During injection molding, the concave mold and the convex mold are closed to form a mold cavity and fixed, and then the injection fluid is injected into the mold cavity. After the product is formed, the concave mold and the convex mold need to be separated, and the molded mold needs to be taken out. However, in real life, we can understand that it is inevitable that some products need to be assembled by snap-on. In this way, it is necessary to reserve a snap-on groove for the product during injection molding, especially for products with inclined snap-on grooves. After cooling and molding, they are usually snapped together with the bottom of the concave mold, which makes it more troublesome for people to demold them, which not only reduces the demolding rate of the product, but also increases the difficulty of the staff's operation. At the same time, people usually use fastening screws to fix the two molds, which causes people to spend more time when opening the mold, which again reduces the demolding rate of the product.
