Abstract
In an injection molding machine, a locking mechanism of a safety cover of the injection molding machine is operated to be in a locked state in a case where injection pressure inside an injection device is equal to or higher than a predetermined value. Accordingly, a maintenance work of the injection molding machine can be performed only in a state in which pressure inside an injection cylinder is sufficiently lowered, so that a risk of jetting of resin is lowered and safety of an operator can be secured.
