Abstract

PURPOSE: To enable to obtain a product without a flash, by constituting a molding part of a product and a part except that so as to enable relative motion in a vertical direction to a parting face at upper and lower, multi-cavity rubber molds.
CONSTITUTION: Unvulcanized rubber is filled to a vacant place 4 where a product is molded, an upper mold 1 and a lower mold 2 are fitted at a parting face 3, put in a vulcanization molding press and pressed and heated between platens 8, 9. In this time unvulcanized rubber is filled in the vacant place 4 and also a part is forced out to the parting face 3, becoming a flash. After vulcanization, molds 1, 2 and platens 8, 9 are taken out from the press and the platen 9 is removed, then the press plate 11 having a protruding part 10 which presses only a circle 5 constituting the vacant place 4 is put on. When the press plate 11 is pressed, the lowest edge 12 of the circle 5 contacts the uppermost edge of the corresponding circle of the lower mold 2, shearing the rubber flash, and the flash is separated mechanically. Besides, this shearing may be done before perfection of vulcanization.
