Technology for casting motor shell

Abstract

The invention discloses a technology for casting a motor shell. The technology comprises the following steps of: mounting a sand core forming die on a core shooting machine; adding die coverage sand into a material storage box of the core shooting machine; heating the sand core forming die; shooting the die coverage sand into the sand core forming die to manufacture a sand core; sintering and forming the sand core; opening the sand core forming die, and taking out the sand core; assembling sand cores of all parts of the shell to form an integrated sand core, so as to obtain a sand shell die; putting the sand shell die into a pouring box to be fixed, pouring iron liquid, and cooling the iron liquid to form a casting; opening the pouring box, and taking out the casting. The technology has the beneficial effects that the working efficiency and the working quality are improved; the working amount of a worker and the labor cost are greatly reduced; the environment pollution is reduced; the waste is avoided.

Description

technical field [0001] The invention relates to a casting process, in particular to the casting process of a motor casing. Background technique [0002] There are two types of casting molding techniques for traditional motor casings: manual molding and machine molding. [0003] The manual molding technology mold is a ground mold (split wooden mold or aluminum mold), and the molding technology is that sand tightening and mold removal are done by people; the machine molding technology mold is a machine mold (medium-plate aluminum mold), and the molding technology is tight sand The molding machine assists people to complete the mold drawing and molding; whether it is manual molding or machine molding, there are some problems in the process, such as: [0004] 1. In the production process, there are high requirements for its personnel modeling technology and auxiliary materials, often due to human uncertain factors or instability of modeling auxiliary materials, resulting in a s...

AI Technical Summary

Problems solved by technology

[0004] 1. In the production process, there are high requirements for its personnel modeling technology and auxiliary materials, often due to human uncertain factors or instability of modeling auxiliary materials, resulting in a substantial increase in the defective rate of its products;

[0005] 2. The mold is easy to wear, which increases the labor intensity in the production process, resulting in low production efficiency, high product defect rate, and high requirements for the control of each process flow in the entire process;

[0006] 3. In the traditional motor casing and end cover casting industry, in order to avoid the increase in the defective rate of products during the production process, the processing reserve of its products must be kept above 2mm, but its yield rate is also kept at about 95% at most, so that it causes Large waste of material and molten iron smelting energy;

[0007] 4. In the production process of surface sand, the environment is often polluted due to heavy dust and difficulty in recycling waste sand;

[0008] In addition, due to factors such as poor production environment and high labor intensity in the traditional motor shell casting industry, the shortage of modeling technicians has become larger and larger. Although the labor cost is continuously increasing every year, the lack of modeling technicians is still serious. The main reason is Because of the excessive labor intensity in the usual production process, the older generation of modeling technical workers must withdraw from this industry early due to the excessive physical strength as they grow older, and the group of young people is unwilling to enter this industry, so the traditional motor industry will be formed.
