Features of green sand casting production line

The complete green sand casting production line is mainly divided into: core shooting machine, molding equipment, molding sand conveying equipment, casting equipment, sand recovery equipment, dust removal equipment, surface shot blasting equipment, etc. Through rationalized layout, the whole green sand casting can be operated efficiently; different casting production lines are selected according to the characteristics of castings, production efficiency, degree of automation, environmental requirements, etc., so as to produce sound and high-quality castings.

The core shooting machine is mainly divided into cold core box core shooting machine and hot core box core shooting machine. At the same time, according to the characteristics of the core box, it can be divided into horizontal type and vertical type. Constrained by the cost, the hot core box core shooting machine is currently widely used. . In order to improve the production efficiency, the core shooting head and core box of the core shooting machine have been upgraded, and the core shooting machine with double shooting heads and double core boxes can be operated by one person, which can make multiple sets of sand cores at the same time, saving labor costs and improving production efficiency.

The molding equipment is mainly divided into: semi-automatic manual molding (Jolt-squeezing moulding machines, Hydraulic multi-piston moulding machine) and automatic molding (removable flask molding machine, Vertical parting boxless molding machine), and different types of molding machines are selected according to the size of the castings. , If the casting is small, it can be designed with multiple pieces in one box, but it is necessary to design a perfect mold plate according to the external dimensions of the casting to ensure a reasonable layout of the casting, and at the same time to ensure the fluidity of molten iron during casting, and the permeability of the sand. High quality castings can be obtained.

The molding sand conveying equipment is mainly used in conjunction with the molding equipment. The semi-automatic manual molding (Jolt-squeezing moulding machines, Hydraulic multi-piston moulding machine) is mainly transported by the electric hoist after the mold is lifted, which can cooperate with the ground rail line for sand conveying; automatic molding ( The removable flask molding machine mainly uses the ground rail line and the open line. Of course, if the output is relatively small, a pneumatic trolley can also be used to manually transport the sand molds and place them on the floor of the workshop for arrangement. The vertical parting boxless molding machine has a matching casting line and cooling section) .

Casting equipment can be divided into manual casting and automatic casting by casting machine according to the degree of automation. Manual casting can use annular ladle casting and orbital ladle casting. equipment.

The sand recovery equipment is mainly to save the casting cost and improve the use efficiency of green sand, and realize the separation of the casting sand through the shakeout machine; the magnetic separator removes the iron bean flash burrs caused by casting in the old sand, and prevents damage to the sand recovery equipment. Sand machine and molding machine; sand screening machine removes the clay blocks condensed by casting to ensure uniform thickness of old sand, preventing sand mold hardness and uneven air permeability during the molding process, resulting in irregular shape of castings; fluidized cooling bed is mainly used for large-scale casting production lines , which can ensure the rapid cooling of the old sand and prevent the sand mold from breaking due to insufficient sand compaction due to high sand temperature; the sand mixer is mainly used for the mixing of green sand, and can be equipped with electronic scales or grid quantizers to achieve quantitative mixing. The quantitative water adding device ensures the humidity of the green sand; the belt conveyor is mainly used for conveying the molding sand and conveying the mixed green sand to the molding equipment.

Dust removal equipment is mainly divided into pulse bag filter and filter cartridge dust collector. The most used in green sand foundry is pulse bag filter combined with centrifugal fan. Dust collector is mainly used for dust removal in casting area and dust removal of old sand recovery equipment. A large amount of smoke and dust will be generated to pollute the working environment of the workshop. When the old sand is regenerated, a large amount of dust will be generated due to the screening and crushing of the old sand. Air permeability, hardness and moisture of sand molds.

The surface shot blasting equipment is mainly selected according to the size of the casting and the amount of cleaning. It is mainly used to improve the smoothness of the surface of the casting. At present, the hook shot blasting machine and the inclined drum shot blasting machine are the most used. The shot blasting machine is equipped with a separate shot blasting machine. Dust removal equipment is used to filter the dust generated by the friction of the steel shot against the casting during the shot blasting process.
