During the product ejection process, the first inclined ejector rod moves obliquely upward and separates from the buckle position. Since the stopper has no inclination, it can only move in the vertical direction Z. The stopper and the product move vertically upward synchronously, so that the stopper can effectively block the buckle position of the product, avoid the product from following the inclined ejector rod to move horizontally, and prevent the product from sticking to the inclined ejector rod during the ejection process, causing the buckle position of the product to be deformed and difficult to remove. When the mold is closed, the stopper moves downward together with the first inclined ejector rod, and the stopper is reset to the inside of the mold core to complete the mold closing.
