とする射出成形金型。 In an injection molding mold for molding a resin product having an undercut portion such as a hole, a core die forming a product molding portion between the cavity die and the core die is installed so as to be movable toward and away from the cavity die,
A slide core for forming the undercut portion is attached to an extrusion block slidably attached to the core die in the moving direction, and the slide core is slidably attached to the extrusion block in a direction transverse to the moving direction, and is inclined with respect to the moving direction. The slide core is connected to a cam block that slides along an inclined guide surface formed on the core die, and the slide core is separated from the undercut by sliding of the extrusion block with respect to the core die. injection mold.
