Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection shell mold. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of patterns and colors, shapes ranging from simple to complex, and sizes ranging from large to small. Furthermore, the product has precise dimensions, is easy to update, and can produce parts with complex shapes. During the shell production process, the shell raw material is usually injected into the injection mold before molding can begin.

[0003] Traditional injection molds are usually bolted to the surface of the injection molding table with a variety of fasteners. When the injection mold needs to be cleaned, the staff needs to remove the fasteners one by one and then reinstall them after cleaning. As a result, the disassembly and assembly of the injection mold takes a lot of time, thus affecting the production efficiency of the shell.

[0004] According to the announcement number: CN219055149U, an injection mold for injection molded parts is provided, including a lower template, a lower mold base, an upper mold base and an upper template. The lower mold base is fixedly installed on the upper surface of the lower template, and the upper mold base is arranged above the lower mold base. The upper template is fixedly installed on the upper surface of the upper mold base. The upper template and the lower template have the same size. A central cooling channel is opened at the center position inside the upper template and the lower template. The two sides of the central cooling channel are interconnected with transverse cooling channels. There are no less than two longitudinal cooling channels above and below the two transverse cooling channels and located inside the template. The utility model can effectively solve the technical problem of poor cooling effect at the edge of the square mold and reduced overall cooling efficiency through the covering structural design of several channels. There is no external added structure on the basis of the original structure of the injection mold, which effectively reduces the overall production cost of the injection mold and reduces the purchase cost. It is suitable for the development and use of small and medium-sized enterprises.

[0005] According to the injection mold introduced above, it is usually bolted to the surface of the injection molding table by a variety of fasteners. When the injection mold needs to be cleaned, the staff needs to remove the fasteners in turn and reinstall them after cleaning. As a result, the disassembly and assembly of the injection mold takes a lot of time, which affects the production efficiency of the shell. Therefore, we need to propose an injection shell mold.
