  • Publication number: 20200078994
    Abstract: A spacer (1) is injection molded by using an injection molding die having resin flow channels that are designed such that a plurality of gates (6) are arranged along the longitudinal direction at a position corresponding to the outer peripheral surface of a side wall part (4) in which a plurality of arc-like peripheral surface parts (2) are connected through a waist part (3). After opening the mold and ejecting the spacer, the spacer is cooled with a runner (7) being connected to the gate (6), and thereafter, the runner (7) is cut off. As a result, when producing a water jacket spacer that is assembled to the inside of the water jacket and controls the flow of cooling water by injection molding, while producing with a high productivity without being affected by design constraints caused by draft angle, deformation in the post-molding cooling step is prevented.
