Abstract

PURPOSE:To give up the use of the plunger rod, and to greatly shorten the length of whole of the metal mold casting machine, by attaching the plunger tip to the tip of the piston rod being slidably fitted into the inner tube within the cylinder, and by cooling these parts in one body. CONSTITUTION:The molten metal, in the plunger sleeve 6 of the metal mold casting machine, is poured into the mold by the reciprocating motion of the plunger tip 5. The plunger tip 5 is attached to the tip of the piston rod 4 rigidly attached to the piston 3 sliding in the cylinder 2. In the cylinder 2, the hollow inner tube 7 is installed, and along its outer surface, the inner hole of the piston rod 4 slides. Besides, in the inner tube 7, the cooling tube 8 is arranged so as to reach the spot nearest to the inmost position of the retreated plunger tip 5; this cooling tube 8 cools the piston rod 4, inner tube 7, and plunger tip 5, in one body. In this apparatus, the plunger rod is unnecessary to be interposed between the piston rod 4 and the plunger tip 5, so that the whole length of the apparatus can be greatly shortened.
