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.

The invention discloses a novel whole set structure of a door plate, a door sleeve and hinges. The novel whole set structure comprises a right side frame, a left side frame, an upper side frame and a door plate body. The right side frame is mainly composed of a right outer frame body, a right frame plate and a right inner frame body. The left side frame is mainly composed of a left outer frame body, a left inner frame body and a left frame plate. The upper side frame is mainly composed of an upper outer frame body, an upper frame plate and an upper inner frame body. The door plate body is mainly composed of surrounding columns, side seal plates, a face plate, a core plate and end seal plates. Hinge assemblies are arranged at the upper and lower ends between the door plate body and the left side frame. According to the structure, the large number of labor costs is saved, the large amount of mounting time is saved, and excessive waste of materials is avoided; the strength of the door plate is increased, the cost is reduced, and mounting is better facilitated; the connecting mode of the door plate and the door frames is concealed, and overall attractiveness is achieved; and the structure utilizes a novel assembling mode, the labor intensity of workers and the technical requirement are reduced, the strength of the door structure is strengthened, and the production period is shortened.
