Description

Technical Field

[0001] The utility model relates to the technical field of automobile cover plate processing, in particular to an automobile cover plate mould which is easy to install. Background Art

[0002] Automobile cover panel processing technology involves the manufacture of various covers on the automobile body, such as the engine cover, trunk cover, door cover, etc., which need to meet the requirements of structural strength and durability. When processing automobile covers, injection molds are usually required.

[0003] Automobile cover panel molds usually consist of key components such as an upper mold, a lower mold, an injection port and a molding cavity. The injection port is the channel connecting the injection molding machine and the mold. The molten plastic is injected into the molding cavity through the injection port. The molding 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 screws to ensure that the upper and lower molds can be firmly closed during high-pressure injection molding, and to ensure that the plastic melt is evenly filled in the mold cavity and maintains its shape during the cooling and solidification process. After the mold is fully cooled and solidified after injection molding, the operator needs to remove the screws of the upper mold and the lower mold, and then take out the molded cover panel. This structure requires opening the mold to take out the finished product every time it is used, and the screws need to be disassembled and reassembled. This process is relatively cumbersome and takes a long time, reducing production efficiency.

[0004] Therefore, it is necessary to provide a new automobile cover plate mold that is easy to install to solve the above technical problems. Utility Model Content
