Abstract
An intermediate mold is disposed between a stationary side mold and a movable side mold in a mold unit of an injection molding machine, the intermediate mold includes: a mold section that performs mold opening and closing operations with a facing mold of the stationary side mold and the movable side mold; a rotating frame body that is rotated together with the mold section by a rotary shaft; a support section that supports both sides of the rotating frame body via shaft bodies; and a rotation drive section that transmits a rotational force to the rotating frame body, in which the support section accommodates at least a part of the rotation drive section.

An intermediate mold that is disposed between a stationary side mold and a movable side mold in a mold unit of an injection molding machine, the intermediate mold comprising:
- a mold section that performs mold opening and closing operations with a facing mold of the stationary side mold and the movable side mold;
- a rotating frame body that is rotated together with the mold section by a rotary shaft;
- a support section that supports both sides of the rotating frame body via shaft bodies;
- and
- a rotation drive section that includes a rotational force transmitting portion and transmits a rotational force to the rotating frame body via the rotational force transmitting portion,
- wherein the support section accommodates the rotational force transmitting portion at a position deviated from an extension line of the rotary shaft in a radial direction, and
- a rotational axis of the rotation drive section is parallel to the rotary shaft.
A mold unit of an injection molding machine, the mold unit comprising:
- an intermediate mold disposed between a stationary side mold and a movable side mold,
- wherein the intermediate mold includes
- a mold section that performs mold opening and closing operations with a facing mold of the stationary side mold and the movable side mold,
- a rotating frame body that is rotated together with the mold section by a rotary shaft,
- a support section that supports both sides of the rotating frame body via shaft bodies, and
- a rotation drive section that includes a rotational force transmitting portion and transmits a rotational force to the rotating frame body via the rotational force transmitting portion,
- the support section accommodates the rotational force transmitting portion at a position deviated from an extension line of the rotary shaft in a radial direction, and
- a rotational axis of the rotation drive section is parallel to the rotary shaft.
An injection molding machine comprising:
- a mold unit that includes a stationary side mold, a movable side mold, and an intermediate mold disposed between the stationary side mold and the movable side mold, the mold unit being mounted in the injection molding machine,
- wherein the intermediate mold includes
- a mold section that performs mold opening and closing operations with a facing mold of the stationary side mold and the movable side mold,
- a rotating frame body that is rotated together with the mold section by a rotary shaft,
- a support section that supports both sides of the rotating frame body via shaft bodies, and
- a rotation drive section that includes a rotational force transmitting portion and transmits a rotational force to the rotating frame body via the rotational force transmitting portion,
- the support section accommodates the rotational force transmitting portion at a position deviated from an extension line of the rotary shaft in a radial direction, and
- a rotational axis of the rotation drive section is parallel to the rotary shaft.
