Abstract
A stationary board adapted to support a metal die and a frame adapted to support an injection cylinder are formed as an integral hollow structure. A sleeve teemed with molten metal extends through the board coaxially with the injection cylinder, and the molten metal in the cylinder is injected into the die by a plunger operated by the injection cylinder. With this construction, the weight of the apparatus is decreased and the rigidity can be increased. Further, not only centering of the injection cylinder is facilitated but also the length of the sleeve can be decreased.
