Abstract
The pin mounting hole used to insert and mount the pin member having a pin-like shape is formed on, among the inner wall surfaces of the cavity, the second side-wall surface that is an inner wall surface other than the inner wall surfaces perpendicular to the mold-removal direction of the injection-molded article. On the second side-wall surface, the protruding portion protruding from the second side-wall surface is formed in the surface area located on the opposite side in the mold-removal direction with respect to the pin mounting hole.
Claims14
A mold for injection molding comprising a stationary-side mold plate and a movable-side mold plate, in which a cavity is formed between the stationary-side mold plate and the movable-side mold plate, and an injection-molded article is injection-molded by charging the cavity with a melted resin, wherein
- a pin mounting hole in which a pin-shaped pin member is inserted and mounted is formed in a side-wall surface, the side-wall surface being an inner wall surface other than an inner wall surface perpendicular to a mold-removal direction of the injection-molded article among inner wall surfaces of the cavity, and
- on the side-wall surface in which the pin mounting hole is formed, a protruding portion protruding from the side-wall surface is formed in a surface area located on an opposite side in the mold-removal direction with respect to the pin mounting hole.
An injection molding machine comprising:
- a mold for injection molding, the mold comprising:
- a stationary-side mold plate and a movable-side mold plate, in which a cavity is formed between the stationary-side mold plate and the movable-side mold plate, and an injection-molded article is injection-molded by charging the cavity with a melted resin, wherein
- a pin mounting hole in which a pin-shaped pin member is inserted and mounted is formed in a side-wall surface, the side-wall surface being an inner wall surface other than an inner wall surface perpendicular to a mold-removal direction of the injection-molded article among inner wall surfaces of the cavity, and
- on the side-wall surface in which the pin mounting hole is formed, a protruding portion protruding from the side-wall surface is formed in a surface area located on an opposite side in the mold-removal direction with respect to the pin mounting hole;
- means for clamping and opening the mold for injection molding;
- and
- melted-resin supply means for supplying a melted resin into the mold for injection molding.
