Molding method and its device for synthetic resin product covered with decorating sheet
专利汇可以提供Molding method and its device for synthetic resin product covered with decorating sheet专利检索，专利查询，专利分析的服务。并且PURPOSE: To eliminate a fear that a sheet material is projected through a molded product like flashes, by a method wherein the title method is constituted so that the sheet material is blanked by a blade part at the time of insertion of a core into a cavity and synthetic resin is formed within an air gap formed of the cavity, a core and a recessed part.
CONSTITUTION: A decorating sheet material A is fed within a sheet material insertion hole 32 from a feed roller and the decorating sheet material A is positioned on the surface of an opening of a cavity 11. A taking out robot 40 of a product is moved away to the first mold member 10 side, the decorating material A is heated with a heater 42 and made into a softened state. Ventilation is performed through an air suction port 13, the decorating sheet material A is stuck close to the inside of the cavity 11 by running the same along the inside and molded. At the time of mold clamping, since a mold member 30 abuts against a core template 22, to begin with, the mold member 30 is pushed and moved to a base part 10a side of the first mold member 10, the sheet material A is blanked with a cooperative action of a blade part 10b
1 provided on a protrusion 10b and a blade part 31b provided on a mold member 30 and an air gap C in a form of a molded product is formed of the cavity 11, a core 23 and recessed parts 24, 31a. Molten synthetic resin is injected into the air gap C and filled out the air gap C.
