Abstract

PURPOSE: To prevent the defects by scattering of the time when molten metal flows into runners and cold shuts by opening and closing runners by a lower sleeve and injecting molten metal into cavities by the operation of a plunger tip and a counter tip.
CONSTITUTION: A cylinder mechanism 31 is operated to lower a lower sleeve 29 and to open runners; at the same time, a counter tip 35 is moved upward by a cylinder mechanism 37 to inject molten metal (a) into cavities 26 by the pressure force of the tip 35. The molten metal (a) injected into the cavities 26 is further pressurized by the tip 35, and the solidification of the molten metal progresses under the pressure thereof. Then, the molten metal (a) once stops on the tip 35; thereafter, runners 27 are opened by descending of the sleeve 29 and therefore the molten metal (a) goes gently into the runners 27 without running fast or scattering into the cavities 26, whereby the formation of cold shuts when the molten metal is later poured by the counter tip 35 is prevented.
