Abstract
In an injection molding machine including a base, a pivot pin provided on the base, and an injection unit supported by the pivot pin so as to be pivotable relative to the base in a pivoting direction, the injection molding machine is equipped with a rod-shaped member configured to cause the injection unit to pivot in the pivoting direction by pushing the injection unit, and a first support member provided on the base and configured to be screw-engaged with the rod-shaped member.
Claims13
An injection molding machine comprising:
- a base,
- a pivot pin provided on the base, and
- an injection unit supported by the pivot pin so as to be pivotable relative to the base in a pivoting direction, wherein the injection unit includes a heating cylinder and the pivot pin is arranged on an axial line of the heating cylinder,
- a rod-shaped member configured to cause the injection unit to pivot in the pivoting direction by pushing the injection unit;
- and
- a first support member provided on the base and configured to be screw-engaged with the rod-shaped member,
- wherein the rod-shaped member includes a distal end part that pushes the injection unit when the pivot pin is in a state of being off an axial line of the rod-shaped member in plan view;
- the first support member comprises a rotating shaft provided so as to be rotatable relative to the base in the pivoting direction, and a rod-supporting member supported by the rotating shaft and having, formed therein, a through hole through which the rod-shaped member penetrates;
- and
- in the rod-supporting member, a threaded groove configured to be screw-engaged with the rod-shaped member is formed on an inner surface of the through hole.

An injection molding machine comprising:
- a base slidably provided above a machine base,
- a pivot pin provided on the machine base, and
- an injection unit supported by the pivot pin so as to be pivotable relative to the base in a pivoting direction, wherein the injection unit includes a heating cylinder and the pivot pin is arranged on an axial line of the heating cylinder,
- a rod-shaped member configured to cause the injection unit to pivot in the pivoting direction by pushing the injection unit;
- and
- a first support member provided on the base and configured to be screw-engaged with the rod-shaped member,
- wherein when the pivot pin is in a state of being off an axial line of the rod-shaped member in plan view, the rod-shaped member is displaced with respect to the machine base, thereby pushing the injection unit, and
- the first support member comprises a rotating shaft provided so as to be rotatable relative to the base in the pivoting direction, and a rod-supporting member supported by the rotating shaft and having, formed therein, a through hole through which the rod-shaped member penetrates;
- and
- in the rod-supporting member, a threaded groove configured to be screw-engaged with the rod-shaped member is formed on an inner surface of the through hole.
