Abstract

PURPOSE: To raise the productivity of moldings by reducing the loss of material and also by indenpendently separating the injection operation from the vulcanizing operation by a method in which a plasticized rubber is injected through an injection plate with a large number of funnel-shaped material supply ports into a vulcanizing mold to produce plural moldings.
CONSTITUTION: An injection plate 5 is made up of a practically linear upflow end connection 12 and a large number of funnel-shaped material supply ports 10 with a slope 11. A rubber material 3 is injected through the injection plate 5 into the cavity 8 of a vulcanizing mold for producing plural moldings, and after the completion of injection, the vulcanizing mold 6 is removed, another vulcanizing mold 6 is attached, and then the rubber material 3 is likewise injected. The mold 6 so removed is set in another vulcanizing press machine for vulcanization. Thus, the productivity of moldings can be raised because the injection of rubber material and the vulcanization of the rubber material are performed in separate places. Also, no trouble with flash arises and the injection of the rubber material is speeded up because a specific injection plate is used.
