Abstract
PURPOSE: To provide a titled injection pump of enhanced thermal efficiency of a heat insulating furnace and high accuracy in the rate of charging of molten metal by so constituting the same that the molten metal is fed into a die casting machine by a piston immersed in the molten metal in the heat insulating furnace by way of a sleeve in a tightly closely coupled upper part.
CONSTITUTION: A pinion 23 is rotated by driving of an electric motor and a cylinder 19 is moved upward via a guide 21 with rack by using a piston 17 as a guide. As a result, the molten metal 16 flowed in through the hole 26 of the cylinder 19 is supplied into an injection sleeve 12 through the inside hole 17a of the piston 17 with the ascending of the cylinder 19. In this case, the rate of supply of the molten metal 16 into the sleeve 12 is regulated by controlling the moving stroke of the cylinder 19.
