Claims40
A lubrication apparatus for lubricating a feed mechanism of a forming machine, comprising:
- (a) a conversion mechanism for converting rotational motion to rectilinear motion or converting rectilinear motion to rotational motion;
- and
- (b) a lubrication oil circulation pipe including a lubrication oil supply pipe for supplying lubrication oil to the conversion mechanism and a lubrication oil discharge pipe for collecting the supplied lubrication oil.
A lubrication method for lubricating a feed mechanism of a forming machine, comprising:
- supplying lubrication oil through a lubrication oil supply pipe to a conversion mechanism for converting rotational motion to rectilinear motion or converting rectilinear motion to rotational motion;
- and
- collecting the supplied lubrication oil through a lubrication oil discharge pine.
An injection molding machine, comprising:
- (a) a motor,
- (b) a conversion mechanism being configured to convert rotational motion of the motor to rectilinear motion, and
- (c) a lubrication oil circulation pipe including a lubrication oil supply pipe connected to the upper part of the conversion mechanism, and a lubrication oil discharge pipe connected to the lower part of the conversion mechanism.
An injection molding machine, comprising:
- (a) a motor,
- (b) a conversion mechanism being configured to convert rotational motion of the motor to rectilinear motion, and
- (c) a lubrication oil circulation pipe including a lubrication oil supply pipe connected to the conversion mechanism in a direction perpendicular to the axis thereof, and a lubrication oil discharge pipe connected to the conversion mechanism in a direction perpendicular to the axis thereof.
