Claims

[Scope of utility model registration request]

The inner tube is inserted into the outer tube, which is inserted and fixed in a watertight manner into the blind hole of the mold, so as to form a flow path along the axial direction on the outer peripheral surface of the outer tube. a portion protrudes toward the distal end side of the outer cylinder;
A coolant discharge pipe is connected to the rear end of the outer cylinder so as to communicate with the flow path, a coolant supply pipe is connected to the rear end of the inner pipe, and a coolant supply pipe is connected to the rear end of the outer cylinder to communicate with the flow path. A variable cooling range characterized in that a cylindrical body that shields the inner wall surface of the blind hole from the flow of cooling liquid is attached so as to be movable in the axial direction so as to change the length of protrusion toward the tip of the outer cylinder. mold cooling tube.
