Technical Field

The utility model relates to the technical field of pressure plate casting molds, in particular to a pressure plate vertical line casting mold.

Background

The pressure plate is formed by casting, and the traditional gray cast iron pressure plate casting has the problems that a pouring system is solidified before casting, so that solidification shrinkage of the casting cannot be fed, and shrinkage porosity and shrinkage cavity defects are generated. In the prior art, feeding of shrinkage cavity parts of a gray cast iron pressure plate is generally carried out by arranging a riser in a pouring channel. The prior China patent with publication number of CN220278222U discloses a gray cast iron pressure plate pouring structure, which reduces the speed of casting liquid flowing into a pressure plate casting mould by properly increasing the cross section area of a cross runner, reduces the scouring force of the casting liquid, ensures that the filling is more stable, is beneficial to eliminating the sand washing defect of the casting, and can realize the feeding of the casting while the cross runner is used as a runner, so that the final solidification part of the casting is positioned in the cross runner, is beneficial to eliminating the shrinkage cavity defect of the casting, and basically does not reduce the utilization rate of materials.

However, the prior art solution described above has the following drawbacks:

The riser is not easy to fill during casting of the existing casting mold, the hot feeding effect is general, and the casting system cannot effectively improve appearance defects of the surface of a casting, so that the product quality is affected.
