[0026] The working principle of the utility model is as follows: the bottom of the ejector rod 5 is fixedly connected to the ejector plate. When the formed product needs to be ejected, the ejector rod at the bottom lifts up the ejector plate, thereby pushing the ejector rod 5 to move upward, and the connecting block 501 at the top of the ejector rod 5 cooperates with the T-slot 301 to push the movable slide block 3 to slide along the surface of the fixed slide block 2, exit the buckle position, and then complete the ejection of the product, and then take the product out.
