发明名称 Molding method and apparatus using film as molding
摘要 A molding method and apparatus capable of reliably removing a molded product without deformation even if the product has a shape difficult to be removed, such as a shape having a plurality of vertical portions. The method of molding a product by using a film sheet, includes the steps of: adapting to operate a pair of film pushing rings disposed facing upper and lower metal molds of a molding apparatus for thermally molding a product by using a film sheet, independently from the upper and lower metal molds; attracting and attaching a molded product to one of the upper and lower metal molds; fixing the ring on the side of the one metal mold; attracting and attaching a pickup jig to the molded product in tight contact therewith, the pickup jig having a surface shape matching the surface shape of the molded product; releasing the attraction and attachment by the one metal mold and moving the pickup jig to displace the molded product from the one metal mold; and moving the fixed ring to an original position.
