Abstract

The utility model discloses a pipe fitting straight tube casting forming die, which comprises a pipe fitting straight tube inner shell core die and a pipe fitting straight tube outer shell core die. The inner shell core die is formed by an inner shell core upper die and an inner shell core lower die. The pipe fitting straight tube outer shell core die is formed by an outer shell core upper die and an outer shell core lower die. After the die closing process, the die cavity of the inner shell core is formed by a gap between the recessed part of the inner shell core upper die and the protrudent part of the inner shell core lower die. The die cavity of the outer shell core is formed by a gap between the recessed part of the outer shell core upper die and the protrudent part of the outer shell core lower die. The pipe fitting straight tube inner shell core upper die and the pipe fitting straight tube inner shell core lower die are a set of dies. The pipe fitting straight tube outer shell core upper die and the pipe fitting straight tube outer shell core lower die are a set of dies. Two sand cores are produced by each set of the dies, so that a complete sand mold is formed by the combination of two of the sand cores. Then the sand mold is buried in a sandbox for the casting operation. By utilizing the pipe fitting straight tube casting forming die, the surface of a final casting is high in smoothness and precision. The casting has less casting defects and the quality of the casting is greatly improved.

Further technical scheme also comprises:
Shell core patrix one end is provided with the sand-spraying hole groove in said, and the cavity behind said sand-spraying hole groove and the upper and lower mould matched moulds of interior shell core is connected; Interior shell core patrix die cavity two ends are provided with the core print chamber, and the corresponding core print of said interior shell core counterdie chamber is provided with corresponding lug boss.
Chamber, said core print chamber wall comprises that the circular arc chamber wall on both sides and the planar cavity wall of bottom constitute.
The shell core patrix is provided with the positioning hole groove that is used for upper and lower mould mould assembly location in said.
The inside of shell core patrix is provided with the heating tube hole slot in said, is used to install heating tube.
Said outer shell core patrix one end is provided with the sand-spraying hole groove, is connected with cavity behind the upper and lower mould matched moulds of outer shell core.
The interior shell core counterdie of shell core patrix and pipe fitting straight tube is one group of mould in the pipe fitting straight tube; Outer shell core patrix of pipe fitting straight tube and the outer shell core counterdie of pipe fitting straight tube are one group of mould; Two cores of every group of die production, after the combination, outer shell core and interior shell core are formed a complete pipe fitting straight tube sand mold in twos; After imbedding sandbox, can pour into a mould.The size of sand-spraying hole groove can be penetrated the sand ability according to core shooter and confirmed.
The utility model has solved the low phenomenon of pipe fitting straight tube casting yield effectively, has improved pipe fitting straight tube finished casting rate, and the cast(ing) surface of producing is highly polished, precision is high, can greatly improve the class of foundry goods.
