Abstract
An injection molding machine includes: a mold clamping unit; an injection unit; and a safety cover that surrounds the mold clamping unit and the injection unit. The safety cover includes a detachable panel that is attached to an opening. The safety cover includes a door portion that moves between a position where the door portion blocks a second portion of the opening and a position where the door portion does not cover the opening. The safety cover has a size that is smaller than the opening but greater than the second portion. A detachable panel has a first stopper that restricts an opening motion of the door portion when only the second portion is open. The safety cover is provided with a second stopper that restricts the opening motion of the door portion when the opening is entirely open and the detachable panel is removed.
Claims5
An injection molding machine comprising:
- a mold clamping unit that opens and closes a mold;
- an injection unit that injects a molding material into the mold;
- and
- a safety cover that surrounds the mold clamping unit and the injection unit,
- wherein the safety cover includes a removable panel that is attached so as to be removable from or attachable to a structure surrounding an opening from which at least one of the mold clamping unit and the injection unit is exposed to an exterior and that blocks a first portion, which is a portion of the opening in a width direction thereof, and a door portion that is supported so as to be movable, along the width direction of the opening, between a first position at which the door portion blocks a second portion, which is a remaining portion of the opening, and a third position at which the door portion does not cover the opening, and that has a size that is smaller than the opening and greater than the second portion,
- the removable panel has a first stopper that restricts a movement of the door portion in an opening direction as a result of the door portion abutting against the first stopper at a second position at which only the second portion is open, and
- the safety cover is provided with a second stopper that restricts the movement of the door portion in the opening direction as a result of the door portion abutting against the second stopper at the third position at which the first portion and the second portion are open in a state in which the first stopper together with the removable panel is removed.
