Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a forming mold for base processing. Background Art

[0002] A forming mold is a mold made according to the shape and structure of an object in proportion, and is used to process materials (such as plastics, metals, etc.) into products with specific shapes and sizes. An injection mold is a special tool used in the plastic injection molding process and belongs to one of the forming molds. It allows plastics to be heated, melted in a controlled environment, then injected into the mold cavity, and cooled and solidified there to form the required plastic products. The design and manufacture of injection molds have an important impact on the quality, cost, and production efficiency of the final products. Injection molds are widely used and almost cover the production of all plastic products, including daily necessities, electronic devices, automotive parts, medical devices, etc.

[0003] When producing the base components in industrial products, a forming mold for processing is used. The mold usually consists of an upper mold, a lower mold, an injection port, and a forming cavity, etc. The molten plastic is injected into the forming cavity through the injection port. The forming cavity determines the shape and size of the final plastic product. During injection molding, the upper mold and the lower mold are generally fixedly connected by bolts to ensure that the upper and lower molds can be firmly closed during the high-pressure injection process, ensure uniform filling of the plastic melt in the mold cavity, and maintain the shape unchanged during the cooling and solidification process. After the injection-completed mold is fully cooled and solidified, the operator needs to disassemble the bolts of the upper mold and the lower mold, and then use tools to take out the formed mold. This structure needs to open the mold to take out the finished product every time it is used, and the bolts need to be disassembled and reassembled. This process is relatively cumbersome and takes a long time, which reduces the production efficiency to a certain extent.
