The invention discloses a self-positioning type pour plug. The self-positioning type pour plug comprises a pour plug plate, pour plug bodies and bolts. The pour plug plate is provided with a plurality of first holes, and the first ends of the bolts penetrate through the first holes and are connected with the pour plug bodies. The aperture of the first holes is 0.1-0.5 mm larger than the diameter of rod parts of the bolts. A movable clearance is reserved between each pour plug body and the pour plug plate. The pour plug bodies can be in clearance fit with material cups on molds. The self-positioning type pour plug can effectively prevent the phenomenon that the pour plug bodies get stuck, thereby being beneficial for improving production efficiency. 本发明公开了种自定位式注塞，包括注塞板、注塞和螺栓。注塞板上设有多个第孔，螺栓的第端穿过第孔并与注塞连接。第孔的孔径比螺栓杆部的直径大0.1-0.5mm。注塞与注塞板之间设有活动间隙。注塞可与模具上的料杯间隙配合。本发明能够有效防止注塞卡死的现象，有利于提高生产效率。
