A kind of ultra-long aluminum alloy beam low-pressure casting mold and casting method thereof

Abstract

The invention discloses an ultra-long aluminum alloy beam low-pressure casting mold, which comprises a mold body, the mold body is composed of a top mold, a bottom mold and two side molds, a sand core is arranged in the bottom mold, and the sand core Steel pipes are arranged inside, and the surface of the sand core is sprayed and baked. The mold support includes a counterweight bottom plate and a vertical plate. The invention adds a steel pipe inside the sand core, and sprays and bakes the surface of the sand core, which can well solve the problems of deformation and gas generation in the manufacturing process of the product, and effectively solve the problems of poor surface quality, low production efficiency, and product scrap rate. For high-level problems, after the casting is cooled, the sand core is shattered and taken out. The mold bracket is easy to move, and it is suitable for different sizes of molds to carry out the mold lifting work, which improves the efficiency of the mold lifting. The disassembly and installation between the mold bracket and the mold is convenient, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy casting, and more specifically relates to a low-pressure casting mold for an ultra-long aluminum alloy beam and a casting method thereof. Background technique [0002] With the continuous improvement of energy saving and emission reduction and the conversion of new and old kinetic energy, aluminum alloy has been widely used in the field of industrial product manufacturing due to its light weight, high specific strength, oxidation and corrosion resistance and other advantages. The aluminum alloy beam is the bearing part of the track of mechanical equipment, and it is also the core component. The traditional material of the beam is cast iron, which is easy to corrode, especially the heavy weight, which largely causes high energy consumption during the operation of the product, and the production process is traditional wood. Mold foundry technology and gravity casting technology have low produ...

AI Technical Summary

Problems solved by technology

The aluminum alloy beam is the bearing part of the mechanical equipment track, and it is also the core component. The traditional beam is made of cast iron, which is easy to corrode, especially the heavy weight, which largely causes high energy consumption during the operation of the product, and the production process is traditional wood. Mold foundry process and gravity casting process, low production efficiency, poor product surface quality, low pass rate, high cost

[0003] Since the length of the beam product is relatively long, generally more than 2 meters, it is easy to cause product deformation during the production process, especially the production process using traditional wood mold foundry and gravity casting technology, making the product difficult to manufacture and waste. The efficiency is very high, resulting in a large degree of waste, and the existing low-pressure casting mold ejection device has difficulty in ejecting the mold, cannot be adjusted according to different size molds, and has the disadvantages of not being widely applicable
