Sand spraying device for shell coating assembly line

Abstract

The invention provides a sand spraying device for a shell coating assembly line, belongs to the technical field of machinery, and solves the problem that a conventional sand spraying device of the shell coating assembly line is not provided with a sand uniformization assembly. The sand spraying device for the shell coating assembly line comprises a box body, a plurality of sand inlet assemblies, the sand uniformization assembly, and a sand circulating assembly, wherein the plurality of sand inlet assemblies are arranged on the box body; sand inlets which communicate with the sand inlet assemblies are formed in the box body; the sand uniformization assembly is arranged on the box body and comprises a sand unloading plate arranged inside an accommodating cavity; a plurality of sand unloading holes used for allowing sand to fall are formed in the sand unloading plate; a plurality of sand uniformization parts are movably arranged on the sand unloading plate; the sand uniformization parts can circumferentially rotate on the sand unloading plate and enable sand to uniformly fall into the accommodating cavity through the sand unloading holes; and the sand circulating assembly is arranged on the box body and communicates with the accommodating cavity. The sand spraying device for the shell coating assembly line has the advantages that the structure is simple, and the sand uniformization assembly is arranged.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a sand shower device, in particular to a sand shower device used in a casing shell production line. Background technique [0002] In the actual production process, precision casting needs to make the mold shell first. The mold shell is specifically made by wax mold dipping-sanding-curing-cleaning and other processes. The production process requires multiple dipping and sanding, layer by layer. Layer covering, this process is called enamel. [0003] In the existing shell enamel process, a sand shower machine is usually used to complete the sand spreading process. The sand shower machine includes a box body. During the working process, the sand can be directly introduced into the containing cavity through the sand feeding component, and falls naturally through the gravity of the sand and covers the surface of the mold. The sand machine is not equipped with a sand leveling compone...

[0003] In the existing shell enamel process, a sand shower machine is usually used to complete the sand spreading process. The sand shower machine includes a box body. During the working process, the sand can be directly introduced into the containing cavity through the sand feeding component, and falls naturally through the gravity of the sand and covers the surface of the mold. The sand machine is not equipped with a sand leveling component, which will lead to the following situations: 1. The sand introduced by the sand feeding component will accumulate at the discharge port on the box body; 2. The sand will naturally fall to the surface of the mold Can lead to uneven sand coverage

[0004] In summary, in order to solve the problem that the existing sand shower device is not equipped with a sand smoothing component in structure, it is necessary to design a sand shower device with a simple structure and a sand smoothing component for the shell lining assembly line
