Die for die casting
专利汇可以提供Die for die casting专利检索，专利查询，专利分析的服务。并且PURPOSE: To prevent the ejection of molten metal to the outside surely by providing a movable liner which presses objects to be cast axially freely slidably by means of a metallic bar to at least either one of a stationary die and a movable die.
CONSTITUTION: A cylindrical liner 11 is fixed to a movable side die plate 15 by means of lock bolts 11a, and a movable liner 12 contacting the liner 11 tightly and slidably is fitted to said liner. A metallic bar 13 is fixed to the liner 12. In the stage of inserting objects to be cast into cavities 7 and performing die casting, if the laminated thickness of laminated iron cores 2 is larger than prescribed thickness, the die clamping between the movable die and the stationary die is transmitted to the bar 13 to elastically deform the bar 13, which in turn slides the liner 12 in a direction X, thereby holding the liner 11 and the die plate 15 tightly by having clearances l
4 , l
5 . Since the micro-difference in the thickness of the laminated layers of the iron cores 2 is absorbed by the liner 12 through the bar 13 having elastic force, the operation is progressed smoothly.
