Claims

[Scope of utility model registration request]

(1) A movable mold or a fixed mold that defines a molded product cavity including an undercut portion has an undercut core disposed in a movable manner, and is in contact with the undercut core and has an undercut. A mold for a molded product having an undercut portion, characterized in that an auxiliary core is provided that is displaced in a direction different from the displacement direction of the processing core.

(2) Utility Model Registration The mold according to claim 1, wherein the amplifier-cut core has an undercut portion in which the auxiliary core is fitted.

(3) Utility model registration In the mold according to claim 2, the undercut core has a first inclined surface perpendicular to its displacement direction, while the auxiliary core has a second inclined surface that abuts the inclined surface. , and the displacement of the auxiliary core is the slope of the 2
A portion of the auxiliary core is configured to apply a force to the molded product in a direction different from the direction of displacement of the undercut core. A mold for molded products that has an undercut.
