Abstract

PURPOSE: To obtain casting rubber molds economically, by placing a gete master and a product master in a frame that can be easily disassembled, introducing a reactive curing type liquid rubber into the frame, followed by curing thereof, disassembling the frame, and opening the rubber mold with a blade tool to remove the masters.
CONSTITUTION: The gate master 8 is secured on the center of the bottom of the frame 7 that can be easily diassembled, and the product master 10 is secured thereon. A thin film that will be released from the casting rubber 5 is applied on one surface of the product master 10 in which through holes 9 such as windows are provided t close the holes 9, then the reactive curing type liquid rubber 5 is introduced into the frame 7 to completely submerge the masters 8, 10 therein, and the liquid rubber is cured. Next, the frame 7 is disassembled, the rubber mold is opened with a sharp blade tool, and the masters 8, 10 in the rubber molds 11, 11' is removed to obtain the aimed casting rubber molds 11, 11'.
