The buckle machine 17 is mainly used to increase the mold opening resistance between the fixed and movable molds to ensure that the runner plate, the panel and the fixed mold plate are opened before the fixed mold plate and the movable mold plate are opened. The safety buckle 18 prevents the movable and fixed molds from opening during the lifting, loading and unloading and transportation of the mold to protect the mold. The water transport hole 19 is used for effective cooling of the mold to keep the mold temperature within a certain range. The inclined guide block 2 5 The slider is pulled forward and backward by the oil cylinder, which is used to move the slider repeatedly. When the slider seat 26 passes through the front and rear molds and opens the mold horizontally, it moves sideways to make it out of the product buckle position.
