Sand coating mold module for casting and sand coating casting technique

Abstract

The invention discloses a casting section sand hanging mold assembly, which comprises a mold main body, a mold bottom, a mold cover, a molding tray and a casting section mold core. The main body of the mold is a cylindrical iron mold with a sunken platform at one end, and several axially penetrating mold holes are arranged in the cylindrical iron mold. The mold bottom is a circular iron plate, and the mold bottom is provided with a circular depression corresponding to the position of the mold hole of the mold main body. The mold-making plate is also a mold cover-like iron plate, and a small through hole is arranged corresponding to the concave part of the mold bottom. The mold core of the casting section is also a cylindrical steel core, which is composed of a large mold core and a small mold core. The diameter of the large mold core is slightly smaller than the circular mold hole, and an axial through hole is set in the center. In the through hole, the number is the same as the number of circular die holes of the mold main body. The mold cover is a circular iron plate with the same diameter as the concave platform of the mold main body. The mold cover is provided with a circular hole corresponding to the position of the circular die hole of the mold main body, and a handle is provided on the mold cover.

Description

Technical field [0001] The present invention relates to a casting section mold, in particular to a casting section hanging sand mold assembly capable of using a sand hanging process to produce a casting section. The present invention also relates to the hanging sand casting section process of the above-mentioned mold assembly. Background technique [0002] The casting section is a grinding medium used in metallurgy, energy, building materials, chemical and other industries. It is a small cylindrical rod with specifications from to There are more than a dozen kinds. However, the traditional production process is simple and backward. It is to drill corresponding holes in the cast iron plate, which is the mold, such as figure 2 As shown, a die hole 16 is provided on the cast iron block 15, and then molten iron is sequentially injected into the hole to form. Turn over the iron plate again, and the casting section will fall due to its own weight and the casting slope. At present, h...

Problems solved by technology

This will waste a lot of non-renewable resources every year

[0006] At the same time, the existing casting section cannot open the international market. Foreign businessmen have very strict requirements on the appearance of the casting section, and products produced by traditional techniques cannot meet their requirements.
