Embodiment Construction
[0021] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.
[0022] Die-casting mold vacuum device embodiment:
[0023] like figure 1 Shown, the present invention comprises frame 11, and frame 11 comprises frame top plate 11.1, frame foot 11.2, and frame 11 is provided with the frame bottom plate 11.3 that is used to place operating tool at the lower end of frame foot 11.2. The top plate 11.1 of the frame is provided with a vacuum tank 9, a water storage tank 6, a lift pump not shown in the figure and corresponding devices supporting the lift pump. The top of the vacuum tank 9 is provided with a water spray head 7 , one end of the water pipe 8 is connected with the water storage tank 6 , the other end of the water pipe 8 is connected with the water spray head 7 , and the lift pump is located on the water pipe 8 . The upper end of the vacuum tank 9 is connected...

The invention relates to a pressure casting die vacuumizing device which comprises a rack, a vacuum can, a water storage tank, a lift pump, a water spray head, a water pipe, a steam switch valve, a vacuumizing pipe, a slag removal door and a die vacuumizing valve, wherein the vacuum can is connected with a steam exhaust pipe. The vacuum can communicates with a water inlet pipe, and cold water injected into the vacuum can submerges corresponding parts of an electric heating pipe and a slag receiving tank. An upper platen of the rack is provided with a water receiving tank coaming, the water storage tank communicates with a water receiving tank, cooling water sprayed to the vacuum can drops in the water receiving tank and flows back into the water storage tank through the water receiving tank. A vacuumizing operation process comprises the steps: injecting the cold water and turning on an electric heater for heating water in the vacuum can; starting the lift pump to spray the cold water to the vacuum can, and thus forming certain negative pressure in the vacuum can; closing the lift pump and stopping spraying, and thus enabling the vacuum can to be at negative pressure; opening the die vacuumizing valve to vacuumize a die; and when air pressure in the vacuum can is over a certain value, starting a new round of vacuumizing operation.
Description
technical field [0001] The invention relates to a novel die-casting mold vacuuming device used for vacuuming and exhausting the die-casting mold in die-casting production and a corresponding vacuuming operation process. Background technique [0002] During the die-casting process, if the air in the die-casting mold is not completely excluded, the die-casting products obtained through die-casting production are prone to defects such as pores and cold shuts. Therefore, the die-casting mold vacuum device has become an important production auxiliary equipment device for die-casting casting production. The main function of this important production auxiliary equipment device is to vacuumize the gas in the die-casting mold through the corresponding die-casting mold. The equipment is vacuumed and exhausted, so that the die-casting operation can be completed well, and then the products obtained through die-casting are avoided from defects such as pores and cold shuts. But the die-c...
