ーブ潤滑装置。[Claims for Utility Model Registration] An injection sleeve into which molten metal is injected, a plunger tip that injects the molten metal from the injection sleeve into a mold cavity, and a sleeve lubricant injection device that injects lubricant onto the inner surface of the injection sleeve. In the injection sleeve lubrication device for a die casting machine, one or more notches are cut on the outer periphery of the plunger tip from the end on the plunger rod side to the middle of the plunger tip in the cylindrical direction, leaving a land portion. The plunger tip is pushed out toward the mold cavity side of the injection sleeve, and the plunger rod side of the plunger tip is left inside the injection sleeve, so that the injection is carried out through the gap formed between the notch and the inner diameter of the injection sleeve. The inside of the sleeve is communicated with the mold cavity side, and lubricant is injected onto the inner surface of the injection sleeve by the sleeve lubricant injection device provided at the injection cylinder side opening of the injection sleeve. Features: Injection sleeve lubrication device for die-casting machines.
