Abstract
The invention relates to an inclined ejecting mechanism used in a mold. The inclined ejecting mechanism comprises an inclined ejecting part, an inclined ejecting rod, a guiding block and an inclined ejecting base. The two ends of the inclined ejecting rod are hinged to the inclined ejecting part and the inclined ejecting base respectively. A through hole is formed in the guiding block. The inclined ejecting rod penetrates the through hole in the guiding block and can move in the axial direction of the through hole. A ball or roller is arranged in the through hole of the guiding block. The inclined ejecting rod makes contact with the ball or roller. Sliding friction between an inclined ejecting rod and a guiding block of a traditional inclined ejecting mechanism is changed into rolling friction, abrasion of the inclined ejecting rod is greatly reduced, and the service life of the inclined ejecting mechanism is prolonged.
