The die casting process is characterized in that high pressure is applied to molten metal by utilizing the inner cavity of a die, a die casting machine is a machine for pressure casting and comprises a hot pressing chamber and a cold pressing chamber, the die casting machine hydraulically shoots molten metal into the die under the action of pressure to be cooled and molded, and a solid metal casting can be obtained after the die is opened.
After the existing die casting machine is opened, a manipulator is generally adopted to control the spray head to move, and cooling water is sprayed on the die, so that the water spray cooling of the die is realized. Because the temperature of the die is too high, water is gasified to form a large amount of water vapor, and the water vapor is mixed with some waste gas generated by substances such as a release agent. The water vapor can cause excessive moisture in the workshop, thereby causing easy rusting of equipment, polluting the workshop environment and affecting the health of staff.
In order to solve the technical problem, a mechanism (201922301819.2) for collecting oil mist and waste gas of a die casting machine is proposed, comprising a supporting seat arranged on the die casting machine, a collecting cover is arranged on the supporting seat and is of a funnel-shaped structure with a downward opening, the collecting cover is divided into a fixing part and a moving part from the middle part, the fixing part is fixed on the supporting seat, a flange opening is arranged at the top of the fixing part, a sliding block and a guide rail are arranged below the moving part, the sliding block and the guide rail are respectively fixed on the moving part and the supporting seat, and the sliding block is in sliding connection with the guide rail. The flange port is for connection to an external exhaust treatment system.
The die casting machine oil mist exhaust gas collection mechanism can reduce exhaust gas diffusion, but still has some defects: 1. exhaust gas and water mist easily leak from between the fixed part and the moving part, thereby affecting the water mist and exhaust gas collection rate. 2. The flange opening is positioned on the top wall of the fixed part, the fixed part is usually arranged above the fixed machine head of the die casting machine, and a large amount of water mist and waste gas can be generated when the fixed die and the movable die are cooled; and when the cooling is performed, the die is in an open state, the distance between the movable die and the flange opening is larger, so that a large amount of water mist and waste gas generated by cooling the movable die overflow, and the water mist and waste gas collection rate is influenced. 3. The pipe diameter of the flange opening is usually smaller and is generally not more than 30cm; the pressure difference between the flange opening area and other areas is large, namely, the pressure of the collecting cover is uneven, dead zones are very easy to generate, water mist and waste gas are very easy to overflow, and the water mist and waste gas collecting rate is further affected. 4. The collecting cover is connected with an external waste gas treatment system through a pipeline, so that the flow resistance of air flow can be increased, the water mist and the waste gas collecting rate are affected, the water mist is condensed on the inner wall of the pipeline, a large amount of water drops downwards at the flange opening, and then drops on the die casting machine.
