PURPOSE: To hold the aesthetic appearance of the surface of a resin while holding the airtightness between the resin and rubber by providing an enclosure in the vicinity of a molding surface rubber filling space among pressing surfaces and making the cross-sectional shape in the abutting direction of the enclosure taper so as to bite in the outer surface of a resin already molded product at the time of the abutting of both molds. CONSTITUTION: The abutting surfaces 20, 22 of upper and lower molds 14, 18 are abutted to form a molding space 24 and, simultaneously, a switch cover case C is pressed by a pressing surface and the molding space is partitioned to form a filling space 28. Subsequently, both molds 14, 18 are preheated to filling temp. to fill the filling space 28 with a necessary amt. of molding rubber. At this time, the molding rubber in the filling space 28 is dammed up by the enclosure 30 provided in the vicinity of the filling space 28 to be prevented from flowing out to the outer surface of the switch cover case C to prevent the formation of burr. After the molding rubber is completed, the upper and lower molds 14, 18 are separated to take out a resin-rubber integrally molded product wherein a rubber molded product and a resin molded product are integrated. |
