Molding mold and method for producing molded article

A mold for molding comprising a first split mold and a second split mold which are configured to open and close relative to each other, comprising:

• a cavity, a pinch-off portion, a burr accommodating space, and an ejector member,
• wherein the cavity is a space for molding a desired molded product, and an outer surface of the cavity is configured by mating cavity surfaces provided on each of the first and second split molds,
• the pinch-off portion is provided on a mating surface of the first and second split molds so as to surround the cavity,
• the burr accommodating space is a space provided outside the pinch-off portion for accommodating a burr formed around the molded product,
• the first split mold comprises a guide hole at a portion facing the burr accommodating space,
• the ejector member is configured to be able to advance and retract with respect to the burr accommodating space through the guide hole,
• the second split mold comprises a groove-shaped recess provided facing the burr accommodating space and along the pinch-off portion,
• the groove-shaped recess comprises an inner side surface extending from the pinch-off portion toward a bottom of the groove-shaped recess,
• the inner side surface has a first and a second portion, and
• the second portion is provided at a position farther from the pinch-off portion than the first portion and has an inclination angle with respect to a reference plane perpendicular to an opening/closing direction of the first and second split molds that is larger than that of the first portion.
