Description

Technical Field

[0001] This utility model relates to the field of injection molded parts demolding, specifically to an external mold insert demolding device. Background Technology

[0002] With the development of society and the economy, the ownership rate of automobiles is increasing, and car air conditioning filters are receiving more and more attention from car owners.

[0003] Currently, in existing automotive air conditioning filter meshes, the filter frame and the filter mesh are generally integrated into one piece using thermoplastic injection molding technology with a mold as the carrier. The specific process is as follows: hang the pre-cut filter mesh into the mold, close the mold, injection mold the frame, cool and open the mold. However, the molds used for forming the filter mesh and the frame are usually integrated into the manufacturing equipment of the entire filter mesh. Due to the complex structure of the integrated mold, it is difficult to hang the filter mesh into the mold, and it is also difficult to remove the finished product after molding.

[0004] In existing technologies, a separate insert is usually provided. The filter screen is wrapped in the insert and then placed in a mold for injection molding. After injection molding, the insert and the finished product need to be removed from the mold together and separated. Currently, the insert and the finished product are usually separated by hand pulling, which is time-consuming, laborious and easy to damage the finished product. Utility Model Content
