1. 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.
