Mar 12, · The blue rectangular spring is installed next to the ejector return pin, as it has a small inner bore, not suitable to be placed over the pin. Injection Molding Design Deliberations. When cooling of the molten material in the mold, both parts of the metal mold are detached to permit for the elimination of the solid plastic. Therefore, Ejector pin injection molding involves the removal of completed parts from the die molds. Injection molds are built such that when they are opened, the A-side half is lifted, leaving the formed part and the B-side. Shovel wedge is fixed on the plate Slider and clamping block are installed on the B plate. When the mold starts to eject, the ejector pin returns to pin 07 and pushes the stop pin At the same time, the gear pin pushes the B plate 06 forward together.
