Abstract

PURPOSE:To provide the captioned structure capable of removing a side core from a mold plate on the movable side by its horizontal sliding by a method wherein the mold is opened, a return pin support is drawn from a long hole and an angular pin is drawn from an inclined hole. CONSTITUTION:Under a die clamped state molding material is injected into a cavity 12 and a return pin 6 is protruded from an ejector plate 16. The upper end part of the return pin 6 is protruded to the long hole 4, a return pin support 5 is pushed by a pin 6 and a fixed mold part 14 and a movable mold part 9 are separated from a mold-opening surface PL along a guide pin. At this time, the side core 2 slides by l toward the a direction as the side core is guided by an angluar pin 19. The die is opened, the return pin support 5 is taken out of the long hole 4, the pin 19 is taken out of an inclined hole 20 and the side core 9 is slided in the a direction. After that, the side core 2 can be removed from the mold plate 1 on the movable side.
