Abstract
PURPOSE: To enable to remove rubber flash mechanically, by pressing the part of a mold except a bar fitted in a hole after filling the vacant place where a product is molded with unvulcanized rubber in vulcanization molding of rubber by upper and lower molds.
CONSTITUTION: When unvulcanized rubber is filled in a vacant place 4 where a product is molded by an injection method etc., unvulcanized rubber is forced out to grooves 5, 6 and a parting face 3 and becomes a rubber flash. Here, upper and lower molds 1, 2 are pressed by a platen 12 and heat-vulcanization is done, then the platen 12 is removed after vulcanization and a press plate 13 is put on and the molds are pressed, so rubber flashes push on bar objects 10 fitted in many holes 9 provided on the upper mold 1 and are forced out upward, then protruded parts 7, 8 between the vacant place 4 and grooves 5, 6 shear a rubber film of this part and remove rubber flashes. Besides, the rubber flash may be removed by removing the platen 12 and putting the press plate on before vulcanization or during vulcanization, and after that it may be vulcanized.
