In order to achieve the above purposes, the technical scheme adopted by the utility model is as follows:
the utility model provides a novel mould stagnant water bolt, includes a work piece and b work piece, a work piece side is middle to run through and has seted up the circular cone hole, and circular cone hole left side and a work piece surface handing-over department are provided with the circular cone aperture, and circular cone hole right side and a work piece surface handing-over department are provided with the circular cone macropore, are provided with the b work piece in the circular cone hole, and the unilateral tapering of circular cone hole is 5 ~ 10 degrees, and the unilateral tapering of b work piece equals with the unilateral tapering of circular cone hole.
Preferably, the workpiece b is in a shape of a truncated cone, and the conical hole is in a shape of a truncated cone.
Preferably, the diameter of the right end of the workpiece b is 0.2-0.25 mm larger than that of the large hole of the cone, and the diameter of the left end of the workpiece b is 0.2-0.25 mm larger than that of the small hole of the cone.
Preferably, the length of the a workpiece is consistent with that of the b workpiece.
Preferably, the material of the workpiece a is red copper.
Preferably, the workpiece b is made of stainless steel.
Preferably, the a workpiece is in the shape of a cylinder.
Compared with the prior art, the utility model provides a novel mold water stop bolt, which has the following beneficial effects:
through setting up a work piece and b work piece, arrange the position that needs the stifled water with a work piece in, strike in the circular cone hole that b work piece got into a work piece, make a work piece inflation, thereby a work piece can wholly rise greatly, stop up the water shutoff hole completely, because the contact surface in a work piece and water shutoff hole is big, and because this expanding structure, make the butt very firm between a work piece and the water shutoff hole, water pressure is big again also can not influenced, and simultaneously, this structure is very simple, it is very convenient that the workman operates, high efficiency, therefore, this water stop has processing simply, high durability, little space benefit such as also good usefulness.
