。 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 a slide core for forming the undercut portion is attached slidably in a direction transverse to the moving direction, and the slide core is attached to the cavity die in a direction transverse to the moving direction. The drive block, which is now slidable and is slidable along the extrusion block, and the slid core are engaged with each other by an inclined guide formed on the drive block at an angle with respect to the moving direction, and the drive block An injection molding mold characterized in that the slide core is separated from the undercut portion by sliding the slide core against the extrusion block.
