发明名称 COMPRESSION MOLDING TOOL
摘要 There is provided a compression molding tool (10) for producing apertures in a compression molded article. The tool has first and second relatively movable tool halves (12 and 14) each supporting a mold section (30 and 32). The mold section (32) associated with the second tool half (14) includes a movable portion (36) that is relatively movable with respect to the second tool half (14). The first tool half (12) is moved relative to the second tool half (14) until the first and second mold sections (30 and 32) engage each other to form a mold cavity therebetween. Devices for creating apertures (56 and 58) are included on at least one of the mold section (30) and are extended into appropriately configured receptacles (52 and 54) in the other mold section (32) after the mold sections are engaged, but before molding material is forced by compression into the mold cavity. The movable portion (36) of the section tool half (14) is then moved in a molding stroke to force molding material into the mold cavity.
