Full-automatic series core-making center of inorganic precoated sand

Abstract

The invention discloses a full-automatic series core-making center of inorganic precoated sand, which is suitable for the condition of making a core by using inorganic sand. The full-automatic series core-making center comprises an independent core shooting machine and is characterized in that cooling devices are arranged on a sand storing hopper, a sand shooting cylinder, a sand shooting hopper and a sand shooting plate of the core shooting machine, each cooling device comprises insulating interlayers arranged on the outer walls of the sand storing hopper, the sand shooting cylinder, the sand shooting hopper and the sand shooting plate, a hot gas blowing device used for sending hot air into a mould is arranged on the core shooting machine, and positioned above the mould. The inorganic sand is rapidly hardened under a high-temperature environment, thus the hardness required by a process is rapidly realized, and the efficiency of the whole process is improved.

Description

technical field [0001] The invention relates to a core shooting system. Background technique [0002] The continuous development of today's society requires a more environmentally friendly manufacturing industry technology to ensure, especially for the traditional foundry industry, it is more urgent to solve the environmental emission problem of the whole casting process. Before German engineers developed hot core box core sand technology with phenolic resin as binder in the 1940s, traditional foundry sand mainly used inorganic materials as binder, such as clay and silicate Type, aluminosilicate, phosphate, etc. are used as binders to make molding sand materials. Although the traditional inorganic binder molding sand has less impact on the environment than the hot box phenolic resin sand in the process of molding and pouring, and is better in environmental protection, due to the efficiency requirements of modern industrial development, people finally choose pollution.

Problems solved by technology

[0005] When the current core shooting machine uses inorganic coated sand for core shooting, the entire core shooting system (sand storage bucket, sand shooting cylinder, sand shooting bucket, sand shooting board) is at a relatively high temperature during work due to the influence of the environment. Make the molding sand bond during the core shooting process; and when the molding sand is solidified, hot air needs to be blown. The existing core shooting machine does not have a cooling system, a hot air blowing system and a core shooting system suitable for inorganic sand, so it cannot complete the inorganic coating. sand core shot
