PROBLEM TO BE SOLVED: To prevent the leak of coating from a mold cavity without using a special coating leak sealing mechanism in an in-mold coating molding method. SOLUTION: A mold cavity 15 is formed in a state that a gap is provided to a mold parting surface using an in-mold coating mold 100 having the mold parting surface extending in the direction vertical to a mold closing direction. After the mold cavity 15 is formed in this state, it is filled with a resin to form flash to the mold parting surface from the whole periphery of the parting line of the mold cavity. At the time of injection of coating, the flash is held by the mold parting surface to prevent the leak of the coating from the mold cavity. COPYRIGHT: (C)2005,JPO&NCIPI |
