[0022] Embodiment

[0023] Please refer to Figures 1 to 6 As shown: A device for quickly drying the moisture in multiple blind holes on a die-cast part provided in this embodiment includes a horizontally arranged air collecting plate 1. An air inlet pipe 2 is connected to the bottom of the air collecting plate 1. An air outlet plate 4 adapted to the die-cast part 3 to be processed (in this embodiment, taking the die-cast part of an automotive audio support plate as an example, for the structure of the die-cast part of the automotive audio support plate, please refer to Figure 1 and Figure 2 shown) is horizontally provided on the top of the air collecting plate 1. Air outlet holes 41 corresponding one by one to the blind holes 31 on the die-cast part 3 to be processed are provided on the air outlet plate 4. And an air collecting cavity 5 communicating with both the air inlet pipe 2 and the air outlet holes 41 is formed between the air collecting plate 1 and the air outlet plate 4.

[0024] In this embodiment, the number and position of the air outlet holes 41 on the air outlet plate 4 correspond one by one to the number and position of the blind holes 31 on the die-cast part 3 to be processed. As can be seen from Figure 1 shown, there are a total of 15 blind holes 31 on the die-cast part of the automotive audio support plate to be processed in this embodiment. Correspondingly, 15 air outlet holes 41 are also provided on the air outlet plate 4.

[0025] The usage method of the device for quickly drying the moisture in multiple blind holes on a die-cast part according to the present utility model is as follows:

[0026] Flip the die casting 3 to be processed so that the side with the blind hole 31 faces downward, then place the die casting 3 to be processed on the air outlet plate 4, and make the hole positions of the blind holes 31 on the die casting 3 to be processed correspond one by one to the hole positions of the air outlet holes 41 on the air outlet plate 4. Connect the inlet pipe 2 to external compressed air. The compressed air enters the air collection cavity 5 between the air collection plate 1 and the air outlet plate 4 through the inlet pipe 2, and then sprays out from the air outlet holes 41. The sprayed gas enters the blind holes 31 at the corresponding positions. In this way, each blind hole 31 can be accurately dried simultaneously.

[0027] As can be seen from the above, by using the device provided by the present utility model, the moisture in multiple blind holes on the die casting can be quickly dried. Not only is the drying efficiency high, but also the drying effect is good. It can effectively avoid the problem of missed blowing, and ensure that the moisture in each blind hole can be quickly dried. Moreover, the device of the present utility model also has the advantages of simple structure, convenient use, high degree of automation, etc., and has significant practical value for improving the production of die castings with multiple blind holes.

[0028] In this embodiment, please also combine Figure 5 and Figure 6 As shown, a gas collection groove 11 is provided at the top of the gas collection plate 1, and the air outlet plate 4 covers the gas collection groove 11, thereby forming an air collection cavity 5 that is communicated with both the inlet pipe 2 and the air outlet holes 41 between the gas collection plate 1 and the air outlet plate 4. Specifically, an air inlet hole 12 is vertically penetrated through the middle position of the gas collection groove 11 on the gas collection plate 1, and the inlet pipe 2 is communicated with the air inlet hole 12, and then communicated with the air collection cavity 5.

[0029] In this embodiment, the aperture of the air outlet hole 41 is smaller than the aperture of the blind hole 31 on the die casting 3 to be processed, so that the gas can better enter the blind hole 31 through the air outlet hole 41, and then the moisture in the blind hole 31 can be dried centrally.

[0030] In this embodiment, please also combine Figures 1 to 4 As shown, a plurality of positioning pins 6 adapted to the die casting 3 to be processed are vertically provided at the top of the gas collection plate 1. In this embodiment, one end of the die casting 3 to be processed has two mounting holes. Correspondingly, two positioning pins 6 respectively corresponding to the mounting holes are provided on the gas collection plate 1. The die casting 3 to be processed can be fixed and positioned through the positioning pins 6 to effectively prevent the die casting 3 to be processed from shaking during the drying process, thereby ensuring the drying effect.

[0031] In this embodiment, the device further includes a horizontally arranged bottom plate 7. The gas collection plate 1 is horizontally arranged on the top of the bottom plate 7. Brackets 8 are symmetrically provided on both sides of the bottom of the bottom plate 7. The bottom plate 7 and the brackets 8 can play a role in fixing and supporting components such as the gas collection plate 1 and the air outlet plate 4.

[0032] Finally, it is necessary to point out here that the above description is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
