Automatic vacuumized negative pressure molding machine

Abstract

The invention discloses an automatic vacuumized negative pressure molding machine. The automatic vacuumized negative pressure molding machine is provided with a rack, wherein a guide rail and at leasttwo molding sand feeding hoppers are arranged on the rack, and a film laminating machine and a molding mould are arranged at the front side of the rack; a gear rack is arranged on the guide rail; thefilm laminating machine is provided with a support platform, a left side supporting seat and a right side thin film cutting device are arranged on the support platform, a transverse movement supporthung on the guide rail is arranged at the upper side of the support platform, a driving motor and a longitudinal movement support are arranged on the transverse movement support, a gear meshed with the gear rack is arranged at the output terminal of the driving motor, and a negative pressure frame is arranged at the lower end of the longitudinal movement support; and a transmission mechanism is arranged between the molding mould and the molding sand feeding hoppers, and a baking mechanism is arranged at the front side of each molding sand feeding hopper. The automatic vacuumized negative pressure molding machine disclosed by the invention is simple in structure, high in automation degree and easy to operate, molding sand in a sand box is compacted by adopting a vacuumizing manner, the smoothness of the surface of a cavity of a sand mould is guaranteed, and further the yield of cast and moulded castings is guaranteed.

Description

technical field [0001] The invention relates to a molding machine, in particular to a vacuum negative pressure automatic molding machine. Background technique [0002] A molding machine is a casting device used to make sand molds. Its main functions include: filling sand, filling loose molding sand into the sand box; compacting sand, compacting the loose molding sand in the sand box through different methods such as vibration compaction, compaction, shock pressure, and injection pressure, so as to make the sand mold It has the necessary strength in the process of handling and pouring; the mold is lifted, and the pattern is taken out of the compacted sand mold by using different mechanisms. Based on the above functions, the existing molding machines are mainly classified into compacting molding machines, vibration compacting molding machines, vibration pressing molding machines and injection molding machines. However, during use, it is found that the above-mentioned molding...
