Problems solved by technology

[0002] The diversion casing of submersible pumps widely used at present has been manually making the sand mold of the core box of the diversion casing blade and extracting the blade manually. In the molding process, there are defects such as high labor intensity, long time consumption, low production efficiency, and high scrap rate. Unnecessary waste of materials and energy
The coated sand molding method is faster than the manual molding method, not easy to deform, has a high degree of smoothness, and has no pollution to the environment. It mainly solves the existing problems of high labor efficiency, low production efficiency, high scrap rate, cumbersome process, and large capital investment. Problem, in order to overcome the defects and deficiencies of the above-mentioned prior art, coated sand casting has been widely used in products in other industries, but when making sand molds for submersible pump diversion shell blade core boxes, due to the particularity of multi-angle distortion of blades, making During the molding process, the blades are difficult to pull out, so the sand mold making of the coated sand diversion shell blades has not been realized by any unit or individual

Embodiment Construction

[0024] Such as Figure 1-3 As shown, the present invention includes a shell core sand mold 1 that is compatible with the inner cavity of the submersible pump diversion shell, at least two blade passages 2 that are arranged on the shell core sand mold 1 and are adapted to the blades, and corresponding to the blade passages 2 The blade mould, the blade channels 2 are arranged in a circular array based on the axis line of the shell core sand mold 1.

[0025] Further, the riser is arranged on the lower end surface of the shell core sand mold 1, so as to optimize the process and facilitate casting.

[0026] Furthermore, the median line of the shell core sand mold 1 is the parting line, thereby optimizing the process and facilitating box closing and unpacking.

[0027] Such as figure 2 , 3 As shown, the auxiliary tooling used to manufacture the present invention includes an upper mold 5 arranged on the sand injection machine 3 and corresponding to the shell core sand mold 1, a l...

Abstract

The invention relates to a submersible pump guide shell vane precoated sand mold and a manufacture method thereof, comprising a shell-core sand mold matching with a submersible pump guide shell inner cavity, at least two vane passages arranged on the shell-core sand mold and matching with vanes and vane molds corresponding to the vane passages, the vane passages being peripherally arrayed based on an axis of the shell-core sand mold; the method is reasonable in process, and the sand mold is high in molding speed, free of deformation, high in gloss, environment-friendly, low in cost, ingenious in design, reasonable in structure and solid and durable.

Description

technical field [0001] The invention relates to a submersible pump diversion shell vane film-coated sand mold and a manufacturing method thereof. Background technique [0002] The diversion casing of submersible pumps widely used at present has been manually making the sand mold of the core box of the diversion casing blade and extracting the blade manually. In the molding process, there are defects such as high labor intensity, long time consumption, low production efficiency, and high scrap rate. Cause unnecessary waste of materials and energy. The coated sand molding method is faster than the manual molding method, not easy to deform, has a high degree of smoothness, and has no pollution to the environment. It mainly solves the existing problems of high labor efficiency, low production efficiency, high scrap rate, cumbersome process, and large capital investment. Problem, in order to overcome the defects and deficiencies of the above-mentioned prior art, coated sand cast...
