Pump housing casting equipment

Abstract

The invention provides pump housing casting equipment. The pump housing casting equipment comprises a small chamber, leakage holes, a guide tube and an electrical appliance cabinet, wherein a bottom plate is of a cross structure; a base for supporting ground is mounted at each of four sections of the bottom surface of the bottom plate; two slide slots are formed in the top surface in the horizontal direction of the bottom plate; the bottom plate is in sliding connection with a slide block on the bottom surface through the two slide slots and a slide base; a first bracket is positioned at the rear side of the top surface of the bottom plate, and casting liquid is injected into the first bracket and flows in a switching mode, so that liquid uniformly flows more sufficiently in a mould cavity, and the liquid can flow into each forming corner of the mould cavity more comprehensively, and therefore, the quantity of vapor bubbles is reduced, the pump housing casting equipment is suitable forcasting and forming production of a pump housing with a relatively complex structure; and vapor bubbles are reduced, so that the quantity of sand holes after the housing is formed can be effectivelyreduced, and therefore, quality of products is improved.

Description

technical field [0001] The invention belongs to the technical field of casting equipment, and in particular relates to casting equipment for a pump casing. Background technique [0002] Casting is a kind of metal thermal processing technology mastered by human beings earlier, with a history of about 6,000 years. China has entered the heyday of bronze castings between 1700 BC and 1000 BC, and the craftsmanship has reached a very high level. Casting is a method in which liquid metal is poured into a casting cavity adapted to the shape of the part, and after it is cooled and solidified, the part or blank is obtained. [0003] Some casting devices for pump casing casting, such as application number: 201720089720.9 provides a high-pressure pump body casting mold, including the mold body, the mold body is also equipped with an adjustment device and a negative pressure pump. The spring, the end and the top of the lifting column are respectively connected to the upper surface of t...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a pump casing casting equipment to solve the existing casting method of injecting pouring liquid into the cavity mold embryo, so that the liquid can be melted according to the shape of the model in the cavity mold to form the required parts products , when applied to the manufacture of pump casings, because the shape of the pump casing is relatively complex, and there are many structures involving bending and drafting, so in the process of liquid injection into the mold with this fixed structure, it is not enough to just wait for it to stand still. Because it is difficult to control the flow of liquid in the mold, the liquid flowing into the complex structure will be uneven, and bubbles will be formed, which will cause trachoma in the formed shell, resulting in defects in product quality
