Problems solved by technology

[0002] In the past, the material of rotary castings was ductile iron, and there were many hot nodes in the casting mold. The valve core hole inside the casting was small and long, which was prone to hole deformation defects, and the casting was prone to shrinkage cavity and shrinkage porosity.
[0003] And because the casting is high, the wall thickness is relatively unable to meet the main feeding requirements. We put the riser on the end face of the casting and use gravity feeding to solve the shrinkage cavity and porosity defects of the casting, but the result is not very ideal. Although it can solve the shrinkage of the casting Loose defects, but does not guarantee the size requirements between casting valve holes

Abstract

The invention relates to a multi-rubber rotary body casting. The multi-rubber rotary body casting comprises a base and a matrix. The base is in a cube shape. The matrix is in a two-step columnar shape. The second step of the matrix is connected with one end face of the base. Four oil outlets are evenly arranged on the second step of the matrix by a circle, and the four oil outlets are distributedin a staggered manner in the axial direction of the matrix. Four oil inlets are evenly arranged on the other end face of the base. The oil inlets and the oil outlets are in one-to-one correspondence and are connected through runner holes formed in the rotary body casting. Design is reasonable, the structure is simple, the defect of shrinkage porosity of the casting is overcome, and meanwhile the size of each runner hole in the rotary body casting can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of pouring, in particular to a multi-channel rotary body casting, a multi-channel rotary body and a pouring mold for pouring the multi-channel rotary body casting. Background technique [0002] In the past, the material of the rotary casting was nodular cast iron, and there were many hot nodes in the casting mold. The valve core hole inside the casting was small and long, which was prone to hole deformation defects, and the casting was prone to shrinkage cavity and shrinkage. [0003] And because the casting is high, the wall thickness is relatively unable to meet the main feeding requirements. We put the riser on the end face of the casting and use gravity feeding to solve the shrinkage cavity and porosity defects of the casting, but the result is not very ideal. Although it can solve the shrinkage of the casting Loose defects, but does not guarantee the size requirements between the valve holes of the cast...
