Title:
CLAMPING DEVICE FOR INJECTION MOLDING
Document Type and Number:
WIPO Patent Application WO/2019/150582
Kind Code:
A1
Abstract:
It is necessary to match the center of a nozzle of an injection molding device and the center of a rubber member, without generating resistive force, through an operation of matching the nozzle of the injection molding device to a sprue of the rubber member. The problem is solved by this clamp device for an injection molding device in which wax stored inside a tank passes through a nozzle to be injected through a sprue into a rubber mold, inside of which are provided a sprue runner and the sprue communicating with the sprue runner, wherein the rubber mold is formed from two or more rubber members, and each of the two or more rubber members engage at dividing surfaces to form the rubber mold. The clamping device is provided with: a bed which has a loading surface for loading the rubber mold and can move in the extension direction of the nozzle; a pressing device which presses the rubber mold against the bed so that additional load is applied to the dividing surfaces of the rubber mold; and an elastic device which can move the head up and down integrally with the pressing device.
