Casting device for box body type casting of refrigerator liner mold

Abstract

The invention discloses a casting device for a box body type casting of a refrigerator liner mold. The casting device comprises a feed bin which is of a hollow structure; stirring paddles are vertically installed inside the hollow structure; the inner walls of the two sides of the feed bin are each provided with a heating plate; four supporting columns are arranged at the lower end of the feed bin; a part, between the supporting columns, of the feed bin is provided with a material charging hole; a hooping device is arranged at one side of the material charging hole; the hooping device comprises a rotating shaft; the rotating shaft is fixedly installed at one side of the material charging hole and is connected with a first hooping arc and a second hooping arc. The casting device disclosed by the invention is provided with the feed bin so that casting materials are remained inside the feed bin and are uniformly stirred to release air, and thus generation of air bubbles inside a finished product after casting formation is ended can be prevented; casting parts are movably installed inside a casting bin, and a feeding hole communicates with the material charging hole through the hooping device so that the cast parts can be changed by replacing the casting parts, and thus the production cost of a manufacturer can be lowered.

Description

technical field [0001] The invention relates to the technical field of casting devices, in particular to a casting device for refrigerator liner mold box castings. Background technique [0002] Casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold, cooling and solidifying, and cleaning to obtain a casting with a predetermined shape, size and performance. Because the casting blank is almost formed, the purpose of free machining or a small amount of machining reduces the cost and reduces the production time to a certain extent. Casting is one of the basic processes of modern device manufacturing industry. [0003] However, most of the existing casting devices for refrigerator liner mold box castings are simple in structure, high in cost, and poor in casting effect. Traditional casting devices are prone to produce ball bubbles, which make the finished product unqualified, and because the refrigerator liner There are ...

Problems solved by technology

[0003] However, most of the existing casting devices for refrigerator liner mold box castings are simple in structure, high in cost, and the casting effect is not good. There are many types of casting parts required, and the manufacturer needs to prepare multiple sets of casting devices to complete the casting, which increases the casting cost of the production parts. For this reason, we have designed a casting device for refrigerator inner tank mold box castings to solve the above problems. question
