Vacuum forming device for gypsum mold

Abstract

The invention relates to a gypsum casting mold vacuum forming device. The gypsum casting mold vacuum forming device comprises a positioning base, a vacuum forming cabin, a transfer lifting arm and a gypsum vacuum mixing cabin; the vacuum forming cabin and the transfer lifting arm are both mounted on the positioning base through a positioning mechanism; the gypsum vacuum mixing cabin is respectively connected with the positioning base and the vacuum forming cabin through the transfer lifting arm; the gypsum mixing cabin includes a mixing tank, a support leg, a sealing cover, a stirring device and a stirring driving device; and the vacuum forming cavity includes a vacuum chamber, a sealing door, a positioning table, a support frame, a negative-pressure pump, a drainage pipe and a casting tank. On the one hand, the gypsum casting mold vacuum forming device can effectively improve the working efficiency of gypsum mold forming and the mold forming quality and precision, and overcomes the defect that a traditional gypsum mold cannot prepare a fine mold; and on the other hand, the gypsum casting mold vacuum forming device can effectively improve the gypsum mold machining efficiency and reduce the labor cost, effectively prevents the gypsum powder flying phenomenon in the machining process, greatly improves the gypsum mold forming production environment, and reduces the material loss.

Description

technical field [0001] The invention relates to a gypsum mold vacuum forming device, which belongs to the technical field of casting mold equipment. Background technique [0002] At present, in non-ferrous metal casting molding processing, such as aluminum alloy casting molding processing, in order to improve product processing quality and efficiency and reduce production costs, gypsum mold shells have been widely used in this type of processing. In actual production, In order to meet the needs of casting processing, it is necessary to fully mix the mixed solution of gypsum powder and water, and carry out casting molding according to the processed product parts. Since the gypsum mixture needs to have a certain viscosity, the fluidity of the gypsum mixture is relatively weak. Therefore, it is extremely difficult to process some parts molds with precise structures or small volumes, and the processed The stability of the mold quality is poor, and it is difficult to meet the ne...

[0002] At present, in non-ferrous metal casting molding processing, such as aluminum alloy casting molding processing, in order to improve product processing quality and efficiency and reduce production costs, gypsum mold shells have been widely used in this type of processing. In actual production, In order to meet the needs of casting processing, it is necessary to fully mix the mixed solution of gypsum powder and water, and carry out casting molding according to the processed product parts. Since the gypsum mixture needs to have a certain viscosity, the fluidity of the gypsum mixture is relatively weak. Therefore, it is extremely difficult to process some parts molds with precise structures or small volumes, and the processed The stability of the mold quality is poor, and it is difficult to meet the needs of actual use, which severely limits the reliability and scope of application of the plaster mold. Manual operation by personnel, and the gypsum raw material for gypsum mold shell molding is mostly gypsum powder, so it is easy to cause a large amount of gypsum powder to diffuse into the air of the working environment during the process of gypsum mixture configuration, causing serious damage to the working environment pollution, and lead to an increase in the loss of gypsum powder, so in view of this situation, it is urgent to develop an inventive gypsum mold shell molding processing equipment to overcome the shortcomings in current use and meet the needs of actual use
