形金型のスライドコア。 A slide core of an injection mold consisting of a core, a female mold, etc. is comprised of first and second slide cores that are slidable relative to the core and also slidable in directions away from each other. The slide core is provided with a tunnel gate portion, and the first slide core is partially inserted into a cavity formed in the core, and the tunnel gate portion is provided on the slide surface in contact with the opening edge of the cavity. A runner portion communicating with the tunnel gate portion is formed separately at the contact portion where the first and second slide cores can be separated, and a runner portion communicating with the tunnel gate portion is formed separately at the contact portion where the first and second slide cores can separate. is the first when opening the mold.
A slide of an injection mold, characterized in that the slide is provided with holes that are respectively engaged with angular pins that slide one slide core toward the cavity of the core and slide a second slide core in the opposite direction. core.
