ダイカスト装置。[Scope of Claim for Utility Model Registration] A vacuum die casting device that maintains a vacuum in the cavity and injects molten metal in an injection cylinder sleeve into the cavity with a plunger tip, the plunger sliding inside the injection cylinder sleeve. A back pressure adjustment chamber is provided on the outer periphery of a plunger tip, and is integrally connected to an injection cylinder in a vacuum die casting machine in which vacuum pressure is introduced into the back pressure adjustment chamber during injection molding with a plunger tip;
A flat part 8A is provided at the end on the injection cylinder sleeve side, a male screw part 8B protrudes from the flat part 8A, and is bored inside the injection plunger, with one end opening into the flat part and the other end connecting to the vacuum source P. 2nd contacted
An injection plunger 8 equipped with a vacuum pressure introduction path 8C; has a flat part 6A at the end opposite to the flat part 8A of the injection plunger 8, and a male screw part 8B of the injection plunger 8 is screwed into the center of the flat part 6A. A plunger tip 6 is provided with a female thread 6B for mounting, and a back pressure adjustment chamber 7 provided annularly on the outer periphery has a first vacuum pressure introduction path 6C opening at the other end to the rear end flat portion 6A; Furthermore, the rear end flat portion 6A of the plunger tip 6 or the injection plunger 8
A vacuum die-casting device is provided with a ring-shaped vacuum pressure transmission path 9 that opens to both the first vacuum pressure introduction path 6C and the second vacuum pressure introduction path 8C on one of the flat portions 8A.
