ABSTRACT:
A die casting machine is provided with a mold, which comprises stationary and movable mold halves between which a mold cavity is formed and which is clamped by a horizontal clamping force and a molten bath is injected vertically, and the die casting machine comprises an injection sleeve secured to parting surface portions of the stationary and movable mold halves, an injection plunger device disposed below the injection sleeve concentrically therewith for injecting the molten bath into the injection sleeve and press-feeding the molten bath into the mold cavity, and connecting tie rods operatively connecting the injection plunger device to the mold halves. The connecting tie rods each has one end engaged with the parting surface portions of the stationary and movable mold halves so as to suspend the injection plunger device by the stationary and movable mold halves. The tie rods are disposed on the same plane as the location of the parting surface portions of the mold halves symmetrically with respect to a center line of the injection sleeve. The tie rods each have one end formed as an engaging portion having bilaterally expanded portions so as to exhibit substantially T-shaped expanded portions in longitudinal section and the expanded portions are engaged with grooves formed to the parting surface portions of the stationary and movable mold halves.
