Abstract: A method and apparatus for injecting and mold clamping control of an injection blow molding machine, wherein a parison injected downward from a die between mold halves defining a cavity is detected to thereby determine the dynamic locus of its free end. In every run the mold clamping is commanded to start before the end of injection is commanded and is effected according to the clamping operational conditions determined based on the parison locus determined in the instant or preceding run. In one method a clamping starting time is determined by a calculation with a predetermined clamping stroke speed. In another alternative method an initial clamping stroke speed is determined by a calculation with a predetermined clamping starting time and following stroke speed.

Abstract: In a method and apparatus for casting an engine block, a core holding portion located below an open upper mold located above a lower mold fixed on a stationary platen is caused to hold a water jacket formation destructive core surrounding a cylinder bore formation portion. Slide molds divided in a circumferential direction, located between the upper mold and the lower mold, and supported by the upper mold to be opened/closed in a horizontal direction is closed. Mold clamping is performed upon downward movement of the upper mold. A molten metal is injected at a high casting pressure of not less than 300 kg/cm.sup.2 from a molten metal injection sleeve open to a portion at which the lower mold is brought into direct contact with the upper mold.
