Technical Field

[0001] The utility model relates to the technical field of automobile parts die-casting, in particular to a die-casting device for an automobile chassis. Background Art

[0002] Die casting is a metal casting process that applies high pressure to molten metal within a mold cavity, causing the liquid or semi-liquid metal to fill the die cavity at a high rate. The metal then forms and solidifies under pressure, ultimately producing a casting.

Below the mold 4, a transverse tube 18 is fixedly installed in the cooling box 12, and a porous support plate 14 is fixedly installed in the cooling box 12 above the transverse tube 18, which is used to hold the automobile chassis workpiece after die-casting, and the porous design can greatly increase the area of ​​the lower surface of the workpiece that can be blown by the wind, thereby increasing the cooling speed. A booster fan 15 is fixedly installed on the base 1, and an air outlet pipe 16 is fixedly installed at its air outlet end. In order to ensure the stability of the air outlet pipe 16, a reinforcing rib is fixedly installed on one side of the top beam 3, and its bottom end is fixed to the air outlet pipe 16. The air outlet duct 16 is connected, and an air outlet scoop 17 is fixedly installed at the end of the air outlet duct 16, the opening of the air outlet scoop 17 faces downward, and one end of a bellows 19 is fixedly installed on the air outlet duct 16, and the other end of the bellows 19 extends into the cooling box 12 and is fixedly connected to the transverse tube 18, and a plurality of longitudinal tubes 20 are fixedly installed on the transverse tube 18, and a plurality of air nozzles 21 are fixedly installed on the plurality of longitudinal tubes 20. By arranging a plurality of air nozzles 21 on each longitudinal tube 20, a more comprehensive blowing and cooling work can be performed on the lower surface of the workpiece.

[0025] In the above method, in order to allow the molten metal to enter between the die 4 and the punch 6, a pressurized pipe 9 is fixedly installed on the die 4, on which a casting port is opened, and a second hydraulic cylinder 10 is fixedly installed on the mounting plate 2, on whose output shaft a shot punch 11 is fixedly installed, and one end of the shot punch 11 extends into the pressurized pipe 9 and contacts the inner wall of the pressurized pipe 9.

[0026] In this method, in order to reduce the influence of gravity on the output shaft of the first hydraulic cylinder 7, a sliding opening is opened on the top beam 3, and the linkage plate 5 passes through it and contacts its inner wall, and a support rod is fixedly installed in the sliding opening.

[0028] The working principle of the die-casting device for automobile chassis provided by the utility model is as follows:

[0029] During die casting, the output shaft of the first hydraulic cylinder 7 is first activated to retract, so that the die 4 and the punch 6 are engaged. Then, the molten metal is poured into the pressurized pipe 9 through the casting port on the pressurized pipe 9, and the output shaft of the second hydraulic cylinder 10 is activated to extend. The molten metal can then be pushed into the die casting space between the die 4 and the punch 6 by the injection punch 11. After a period of time, the initial part of the automobile chassis can be formed.

[0030] Then the output shaft of the first hydraulic cylinder 7 is started to extend, so that the die 4 and the punch 6 are separated, and the die-casting ejector assembly 8 is started again, and the ejector therein is used to eject the cast workpiece and drop it directly into the cooling box 12. At this time, the output shaft of the first hydraulic cylinder 7 is started again to retract, so that the die 4 and the punch 6 are buckled again and the next die-casting work can be continued;

[0031] At the same time, the output shaft of the third hydraulic cylinder 13 is started to extend, and the cooling box 12 is pushed to the bottom of the air outlet scoop 17. At this time, the booster fan 15 starts to run, and the booster fan 15 generates a relatively strong airflow. These airflows enter the air outlet pipe 16, and a part of them is directly ejected through the air outlet scoop 17 and sprayed on the upper surface of the workpiece, and the other part enters the horizontal pipe 18 through the bellows 19, and then enters multiple longitudinal pipes 20, and finally is ejected through multiple air nozzles 21 and sprayed on the lower surface of the workpiece through the porous support plate 14, so that a comprehensive blowing cooling work can be formed on the workpiece. When the next workpiece has not yet completed the die-casting, the workpiece has completed the cooling work, and then the output shaft of the third hydraulic cylinder 13 is started to retract, and the cooling box 12 is brought back to the bottom of the die 4, and the workpiece in it is immediately taken out, waiting for the next workpiece to be ejected, and this reciprocating process can be carried out.

[0033] The utility model provides a die-casting device for an automobile chassis. The cooling box 12 is provided to temporarily receive the die-cast automobile chassis workpiece.
