RESIN TRANSFER FLOW PATH SWITCHING VALVE FOR RESIN TRANSFER MOLDING MOLD

摘要

The present invention relates to a resin transfer flow path switching valve for a resin transfer molding mold which is able to easily convert a transfer fluid path of a resin remaining in an injection pipe path into a discharge pipe path by being installed between a mold used in resin transfer molding and the injection pipe path supplying a resin when the injection of the resin in the mold is completed. The resin transfer flow path switching valve comprises: a valve body including a piston hole which is formed by penetrating an inner space in longitudinal direction and allows an end of one side to be connected to a mold inner pipe path, a resin supply opening which is formed by penetrating the inside and outside of a side wall and is connected to the injection pipe path and a resin discharge opening which is formed in a line identical to a line in which the resin supply opening is formed in the longitudinal direction, is formed by penetrating the inside and outside of the side wall and is connected to the discharge pipe path; and a piston which has an external diameter corresponding an internal diameter of the piston hole, is inserted into the other side of the piston hole and includes a discharge inducing channel formed at a side of one side in a constant depth along longitudinal direction. The resin supply opening and the mold inner pipe path are connected by opening the end of one side of the piston hole and the resin supply opening in the backward movement of the piston. The end of one side of the piston hole is closed, and the resin supply opening and the resin discharge opening are connected by the discharge inducing channel in the forward movement of the piston.;COPYRIGHT KIPO 2014
