PURPOSE:To seal a sealer prior to corner molding so as to mold corner sections accordingly by bringing a mold component into contact with a heating mold component through a heat insulating material and disposing a cooling mold component with a cooling body in the vicinity of a retaining space. CONSTITUTION:A rubber molded body 100 is disposed in a retaining space 9 and a rubber material is fed into a pot 17 to carry out injection molding. The molding material is passed through a gate 10, injected into a cavity 8 and filled in a cut section 106 to be brought into contact with the rubber molded body 100. A top force 1, an inner plate 5 and a bottom force 3 are added by a heater 13, and a sprue 12, a runner 11, a gate 10 and the molding material in the cavity 8 are vulcanized. A secondary rubber formed body 200 as a seal lip section of curved shape is formed in the cavity 8 and bonded with the primary rubber molded body 100. A bottom force insert die 4, an inner plate 6 and an inner plate insert die 7 are brought into contact with a heating mold component through a heat insulating material 15 and a space 16 and its temperature is low, and as the inner plate 6 and the inner plate insert die 7 are cooled by the cooling water in a cooling water passage 14, a sealer 105 sealed therein is prevented from foaming. |
