AI Technical Summary
Technical Problem
In the current process of vacuuming and dust removal of die-casting molds, the Roots pump needs to be started frequently, resulting in energy waste and failure to effectively utilize the compressed gas generated by vacuuming.
Method used
Design a mold vacuuming device that divides the vacuum tank into a vacuum stabilizing chamber and a compressed gas chamber to store the compressed air generated during vacuuming. This air can be directly used for chip blowing and dust removal, reducing the need for a Roots pump.
Benefits of technology
By storing compressed air, energy consumption is reduced, achieving a highly efficient dust removal effect. At the same time, it facilitates the cleaning of the vacuum tank, reducing energy consumption and equipment maintenance costs.

Abstract
The utility model relates to a die vacuumizing device which comprises an outer box body of a vacuum pump set, a horizontal vacuum tank is arranged in the outer box body, the upper side of the vacuum tank is respectively and fixedly connected with a front-stage vacuum pump and a roots pump through a mounting bracket, and an air outlet of the front-stage vacuum pump is connected with an air inlet of the roots pump through a connecting pipe; a vertical partition plate is inserted and fixed to the inner side of the vacuum tank and divides a cavity in the vacuum tank into a vacuum pressure stabilizing cavity and a compressed gas cavity. An air inlet of the forestage vacuum pump is communicated with a vacuum pressure stabilizing cavity in the vacuum tank through a pipeline, the vacuum tank is fixedly connected with a compressed air inlet pipe and a compressed air outlet pipe which are communicated with the compressed air cavity, and an inlet of the compressed air inlet pipe is connected with an air outlet of the roots pump. According to the vacuum device, the compressed air generated by vacuumizing can be stored in the vacuum tank, so that the stored compressed air can be used during chip blowing and dust removal, the energy consumption can be reduced, and meanwhile, the compressed air can be used for conveniently removing dirt in the vacuum tank.
