徴とする成形用金型の冷却水回路取付構造。[Scope of Claim for Utility Model Registration] 1. A socket portion having a protrusion protruding from the inner wall surface, a guide tube inserted into the socket portion and connecting the flow path, and a guide tube provided on the outer wall of the guide tube. a plug portion including an elastic tongue provided with a claw portion that can engage with the locking protrusion when the cylinder is inserted into the socket portion; is provided so as to be movable on the outer wall surface of the plug within a range that does not interfere with the tongue, and when moved in a predetermined direction, elastically deforms the tongue piece to release the engagement between the latching protrusion and the claw portion. A one-touch joint characterized by comprising an operation ring. 2 The inside of the socket part has a ring shape, and is always urged toward the insertion opening of the guide cylinder by a biasing means, so that when the guide cylinder is inserted into the socket part, the guide cylinder is shaped like a ring. The plug part is provided with a cylindrical wedge body that passes through the inside of the guide cylinder and wedges between the outer wall of the guide cylinder and the tongue piece to ensure engagement between the locking protrusion and the claw part, and the plug part includes: It is movable together with the operation ring and is provided so as not to interfere with the tongue piece, and when the operation ring moves to release the engagement between the locking protrusion and the claw part, the tube is moved. The one-touch joint according to claim 1, further comprising a pressing piece that pushes the wedge-shaped body against the urging force of the urging means to release the wedged connection between the guide tube and the tongue piece. . 3. Connecting a tube that connects to a cooling water circuit provided in a molding die and passing cooling water therethrough to a plug part constituting the one-touch joint according to claim 1 or 2, and cooling the molding die. A molding die, characterized in that a socket portion constituting the one-touch joint according to claim 1 or 2 is provided at the opening of the water circuit, and the end surface of the socket portion on the insertion port side does not protrude from the surface of the mold. Cooling water circuit mounting structure.
