Description

Technical Field

[0001] The utility model relates to the technical field of plastic part molds, in particular to a cooling insert structure for preparing a deep cavity injection molding part mold. Background Technique

[0002] A cooling insert is a special component in mold design. Its main function is to improve the cooling efficiency of the mold, thereby shortening the production cycle and improving the product quality. Cooling inserts are usually located in the high-temperature areas of the mold and achieve rapid heat dissipation through internal cooling channels or special materials. These inserts can be separate components or integrated with other parts of the mold. In injection molds, cooling inserts are particularly important because they can help control the cooling rate of the plastic melt in the mold cavity, thereby reducing internal stress, deformation, and shrinkage of the product. They can have simple shapes such as circular or square, or complex geometric shapes.

[0003] The existing insert structure still has the following problems. Referring to a thin-walled special-shaped insert structure disclosed in the publication number CN217370403U, which includes an insert top, an insert base, and a cooling water channel. The insert top is semicircular and vertically arranged on the insert base. The insert top and the insert base are arc-shaped on the same horizontal plane. The cooling water channel is horizontally arranged inside the insert top and the insert base. The inlet and outlet of the cooling water channel are both located at the bottom of the insert base. This application is integrally formed by 3D printing technology. The overall forming process is simple. At the same time, the cooling water channel arranged inside the insert top and the insert base cools the insert structure, so that the aluminum liquid near the insert structure solidifies preferentially, which can solve the problems of forming pores and porosity in die-casting molds and further improve the yield rate of die-cast motor end covers.

However, the existing inserts are generally fixed by multiple screws to ensure the stability of the insert, resulting in inconvenient disassembly. Therefore, the utility model provides a cooling insert structure for preparing a deep cavity injection molding part mold. Content of the Utility Model
