Integrated molding mould of dead head and casting cavity

Abstract

The invention discloses an integrated molding mould of a dead head and a casting cavity. The integrated molding mould comprises a core injection machine, an upper mould of a casting mould, a molding template of an upper mould closing box of the casting mould, a dead head molding mould, an upper core, and a lower core on the molding template, wherein an injection nozzle of the core injection machine is connected with a sand injection hole of the upper mould of the casting mould; the dead head molding mould is arranged on the upper mould of the casting mould and is provided with a molding hole; the upper mould of the casting mould is provided with a mould hole communicated with the molding hole; the top of the upper core is fixed on the upper end of the dead head molding mould; the bottom end of the upper core and the top of the lower core respectively stretch into the molding hole or the mould hole to be in butt joint; a dead head molding cavity is formed by a cavity among the upper core, the lower core, the molding hole and the mould hole. According to the integrated molding mould disclosed by the invention, the integrated molding of the dead head and the casting cavity is realized, the defects in transportation and installation processes of the dead head are overcome, time and labor are saved, the cost is low, and the quality of a casting product can be guaranteed.

Description

technical field [0001] The present invention relates to the thermal processing technology of metal materials, and relates to the technological equipment of the casting and forming of the wear-resistant material medium. Background technique [0002] With the continuous improvement of the technical level of the smelting and casting industry, a considerable part of mechanized or intelligent production lines are gradually applied to the smelting and casting industry to replace manual operations. Especially in the horizontal parting casting production mode, the pouring riser technology is still at the stage of manual operation, which seriously restricts the development of mechanized or intelligent production lines. [0003] Riser is one of the essential processes for smelting and casting. At present, in the smelting and casting industry, several manufacturing methods commonly used in the production of pouring risers are: [0004] 1. The use of wet film sand is formed by simple ...

AI Technical Summary

Problems solved by technology

It is easy to cause damage to the riser during the handling and installation of the riser, and there is waste. At the same time, a large amount of loose sand is likely to be generated during the installation of the riser. Necessary cleaning must be carried out, which is time-consuming and labor-intensive; especially when the loose sand is not cleaned thoroughly. During pouring, loose sand will be brought into the pouring system by molten metal, directly affecting the quality of casting products
