Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, and in particular to a quick demolding structure for injection molds. Background Technology
[0002] Injection molds are tools used to inject molten plastic material into a mold, forming a product of the desired shape through pressure and cooling. Their working principle involves injecting completely molten plastic material, stirred by a screw at a specific temperature, into the mold cavity under high pressure. After cooling and solidification, the molded product is obtained. Injection molds are essential tools for producing plastic products. An injection mold typically consists of a mold base, mold core, mold cavity, cooling system, and ejection system. The mold base is the foundation of the mold; the mold core is the movable part inside the mold, used to form the internal structure of the product; the mold cavity is the fixed part inside the mold, used to form the external shape of the product; the cooling system cools the mold and plastic during the injection process; and the ejection system removes the product from the mold. Injection molds can be classified into various types, including single-parting-face injection molds, double-parting-face injection molds, injection molds with side parting and core-pulling mechanisms, injection molds with movable molding parts, automatic unscrew injection molds, runnerless injection molds, and right-angle injection molds, etc.
[0003] An existing patent application (CN202321164574.3) discloses a quick-opening shoe sole mold. Its structure includes a movable plate, a fixed plate, a shoe edge mold, a shoe sole mold, and a handle. The movable plate is hinged to the fixed plate. The shoe edge mold fits snugly against the fixed plate. The handle is fixedly mounted on the fixed plate. The fixed plate has a movable groove. The shoe edge mold has a shoe sole placement opening. The shoe sole mold is movably mounted on the shoe sole placement opening with a clearance fit. The bottom of the shoe sole mold passes through the movable groove and the fixed plate. This invention provides a quick-opening shoe sole mold. Material is placed into the shoe edge mold, sealed and fixed by the movable plate, and then heated and molded. After completion, the movable plate is opened, and the bottom of the fixed plate is exposed by lifting the handle. The molded shoe sole is then pushed out along the shoe edge mold, facilitating easy removal of the shoe sole without damage. The removal method is simple and convenient.
[0004] The aforementioned device improves the removal of shoe soles by manually lifting the fixed bottom plate. However, it requires manual operation, which increases the workload of workers, reduces processing efficiency, and the temperature of the mold is usually relatively high when it is first opened, which can easily affect the physical and mental health of workers.
