Turbocharger blank wax casting mold with pneumatic ejector mechanism

Abstract

The invention discloses a turbine blank wax pattern casting mold for a turbosuperchager with a pneumatic jacking mechanism. The turbine blank wax pattern casting mold comprises an upper mold and a lower mold, wherein the upper mold consists of a jacking plate, a wax injection nozzle, a lining ring, a lining plate and a sleeve hoop; the sleeve hoop is arranged on the lining plate through a screw; the lining ring is arranged in a lining ring mounting hole in the lining plate through a screw; the lining plate is arranged on the jacking plate through a screw; the wax injection nozzle is arranged in a wax injection nozzle mounting hole in the jacking plate through a screw; the lower mold consists of a module, a guide plate, a positioning ring, an unlocking plate, a base plate, a handle, a central column with an air flow channel, an air nozzle, a plug screw and a core sleeve; and the pneumatic jacking mechanism is arranged on the lower mold. After a turbine blank wax pattern is cast, high-pressure air directly upwards jacks the turbine blank wax pattern through the air flow channel, so that the adhesive force between the turbine blank wax pattern and the mold is reduced; therefore, when the turbine blank wax pattern is taken out by a user with a hand, the user can easily take out the turbine blank wax pattern perpendicularly with low strength; and the turbine blank wax pattern cannot deform.

Description

technical field [0001] The invention relates to a casting mold, in particular to a wax-type casting mold of a turbine blank of a turbocharger. Background technique [0002] The wax-type casting of the turbo blank of the ordinary turbocharger adopts the method of direct casting of the mold, and the existing wax-type casting mold of the turbo blank figure 1 As shown, it includes upper mold and lower mold. [0003] The upper die is composed of a top plate 1, a wax injection nozzle 2, a lining ring 3, a lining plate 4 and a collar 6, the collar 6 is installed on the lining plate 4 by screws, and the lining ring 3 is installed on the lining plate 4 by screws. In the installation hole of the lining ring, the lining plate 4 is installed on the top plate 1 by screws, and the wax injection nozzle 2 is installed in the installation hole of the wax injection nozzle on the top plate 1 by screws, and the front end of the wax injection nozzle 2 protrudes outside the lining ring 3 .

AI Technical Summary

Problems solved by technology

[0006] This method of taking out the wax-up is simple and convenient, but it has major defects

When taking out the turbine blank wax-type 14, because the turbine blank wax-type 14 is fixed in the mold cavity of the core sleeve 10, and the turbine blank wax-type 14 has not been completely cooled, the wax is relatively soft, such as taking out the direction is not perpendicular to the mold body, but If it has a slope, it may cause the deformation of the turbine blank wax pattern 14 during the removal process, which will affect the positioning datum and dynamic balance in the later processing.
