At this time, the ejector sleeve 18 on the ejector plate 6 can be extended into the lower mold cavity of the movable template 3 to lift the finished product 25 (two-way joint) to facilitate the subsequent removal of the finished product 25. Since the guide column 10 passes through the fixed template 2, the movable template 3, the upper fixing plate 4 of the thread core and the lower fixing plate 5 of the thread core, the guide column 10 can play a limiting role to prevent the fixed template 2, the movable template 3, the upper fixing plate 4 of the thread core and the lower fixing plate 5 of the thread core from shifting in position, and the ejector rod 27 passes through the fixed template 2, the movable template 3, the upper fixing plate 4 of the thread core and the lower fixing plate 5 of the thread core and is connected to the ejector plate 6 to drive the ejector plate 6 to move, and the ejector rod 27 can play a limiting role to prevent the position of the ejector plate 6 from shifting, so that the concentricity and size of the finished product remain consistent.
