Since the auto lamp mould is a large mold and the parting surface is complex, the forming part and the template adopt an integrated structure, that is, the fixed mold A plate of the mold is the fixed mold forming part, and the movable mold B plate of the mold is the moving mold forming part. The advantages of this structure are compact structure, good strength and rigidity, and small size of the mold, which avoids cumbersome processes such as opening the frame, fitting the frame and manufacturing the wedge. http://www.chinainjectionmould.com/plastic-mould/auto-lamp-mould/
