Abstract

The invention provdies a die casting machine, which can properly applying pressure to a solid-liquid coexisting metal, and includes a clamping device 7 which opens and closes and clamps a pair of die halves 101, an injection apparatus 9 which performs injection to the pair of die halves by making a plunger 41 move forward in a sleeve 39 communicated with a space between the pair of die halves, and a control device 47 which controls the clamping device 7 and injection apparatus 9. The control device 47 includes an injection control part 93 and press-use clamping control part 95. The injection control part controls the injection apparatus so as to start the injection in a state where the pair of die halves face each other through a gap. The press-use clamping control part controls the clamping device so that the die contact and clamping are carried out after the start of injection. Further, the injection control part performs control for decelerating the plunger before the plunger stops.

Description

technical field

[0001] The invention relates to a die-casting machine and a forming method of a solid-liquid coexisting state metal. It should be noted that the solid-liquid coexisting state metal may be either semi-solidified metal in which liquid metal is cooled to a solid-liquid coexisting state, or semi-molten metal in which solid metal is heated to become a solid-liquid coexisting state. Background technique

[0002] A technique for shaping a metal in a solid-liquid coexistence state is known. For example, in Patent Document 1, in a die-casting machine having the same structure as a normal die-casting machine for forming liquid metal (melt), semi-solidified metal is supplied to a sleeve passing between molds after mold clamping, and a plunger Forming is performed by injecting the semi-solidified metal inside the sleeve between the molds. In addition, in Patent Document 2, semi-molten metal is conveyed between open molds (injection is not performed), and then the molds...
