Abstract
The invention discloses a mold locking mechanism for an injection molding machine. The mold locking mechanism comprises a base, a movable mold plate, a fixed mold plate, pull rod components, a mold moving oil cylinder, mold locking sleeves, locking holes and locking teeth. A round of flange is arranged on the periphery of each mold locking sleeve. The mold locking mechanism further comprises pressing covers fixedly arranged on the mold locking sleeves. Each pressing cover is provided with an end surface portion abutting against the corresponding flange. Each end surface portion comprises inclined block parts and plane parts, wherein the inclined block parts are uniformly arranged in the circumferential direction of the end surface portion at intervals, and the plane parts are connected with all the inclined block parts. Each flange is provided with an inclined top part matched with the corresponding inclined block part. The number of the pull rod components is two, and the two pull rod components are arranged in a spaced mode. A gear is arranged behind the movable mold plate. A tooth part engaged with the gear is arranged in the circumferential direction of each mold locking sleeve. According to the mold locking mechanism for the injection molding machine, when a mold is opened, the inclined top parts arranged on the mold locking sleeves slide into the plane parts along the inclined block parts of the pressing covers, and accordingly the mold locking sleeves move backwards by a distance so that the locking hole instant impulse received by the locking teeth during mold opening can be reduced.
