Abstract
PURPOSE: To obtain castings having no cavities and shrinkage by moving the lower counter of a vertical die casting machine upward thereby filling molten metal into the product cavity.
CONSTITUTION: For example, the molten metal M in a supplying device 17 is pressurized and is supplied from a pouring port 15 into a chamber S1 via a pipe 16. Next, a counter 12 and a plunger 19 are moved synchronously upward; the pouring port 15 is closed by the counter 12 and the air pressure for molten metal supply is turned off by a limit switch 20. The plunger 9 ascends to open a runner opening 7, then stops. Next, the counter 12 ascends to flow the molten metal into a runner 8 through the opening 7. Along with the ascending of the counter 12, the molten metal fills in a cavity 4. The plunger 9 is lowered to perform final pressurizing. Upon freezing, the upper die 2 is moved upward to open the dies and the product W is pushed out by ejector pins 19. This yields the product having no blowholes and cavities to inclusion of air.
