An outlet 901 is opened at the bottom of the storage rack 90. ​​The height of the outlet 901 is not less than the thickness of one mold and not greater than the thickness of two molds, so that only one mold can be discharged from the outlet 901 at a time. A pusher assembly is fixedly installed on the storage rack 90. When the support plate 20 is in the feeding area, the track block 311 slides in the lower track 62. At this time, the top height of the first clamping plate 30 is not higher than the height of the upper surface of the support plate 20. The pushing assembly pushes the bottom mold of the storage rack 90 to the upper surface of the support plate 20. The second motor 21 causes multiple support plates 20 to rotate, so that the track block 311 slides from the lower track 62 into the upper track 61. During this process, the moving plate 31 slides on the first slide rod 203, so that the first clamping plate 30 moves upward, and the top of the first clamping plate 30 is higher than the height of the upper surface of the support plate 20. Before the support plate 20 enters directly below the drill bit, the air pump 70 is started, and the air is extracted from the moving plate 31, the first fixed sleeve 41 and the second fixed sleeve 51 through the air extraction pipe group, so that the first clamping plate 30 and the third clamping plate 50 move relative to each other, and the two second clamping plates 40 also move relative to each other, clamping and fixing the mold on the surface of the support plate 20. After the mold is fixed and moved directly below the drill bit, the mold is opened. At this time, before the track block 311 leaves the lower track 62, the second valve 812 is closed, and both the first pressure relief valve 35 and the second pressure relief valve 44 are open, allowing outside air to enter the interior of the moving plate 31 and the two first fixed sleeves 41. Under the elastic force of the second spring 43, the two second clamping plates 40 move in opposite directions; under the elastic force of the first spring 34, the first clamping plate 30 moves towards the other end of the moving plate 31. Then, the second motor 21 continues to rotate the multiple support plates 20, causing the support plates 20 to move to the unloading area. The track block 311 then slides from the upper track 61 into the lower track 62, and drives the moving plate 31 to slide on the first slide rod 203. The first clamping plate 30 moves together with the moving plate 31, so that the top height of the moving plate 31 is not higher than the height of the upper surface of the support plate 20. The vacuum pump 70 continues to extract air from the second fixed sleeve 51 through the vacuum pipe assembly, causing the third clamping plate 50 to continue sliding in the first sliding port 201. During the movement of the third clamping plate 50, the mold can be pushed onto the conveyor belt 100, and the mold with the hole completed is then transported to the next process by the conveyor belt 100. After the mold is transferred onto the conveyor belt 100, the vacuum pump 70 stops working, and the third pressure relief valve 54 opens. Under the elastic force of the third spring 53, the third clamping plate 50 moves and resets. In the above process, workers only need to replenish the molds in the storage rack 90 periodically. The whole process is highly automated, and the equipment has advantages such as simple structure and low manufacturing cost. It can continuously open the molds and has high processing efficiency. It should be noted that the pusher assembly includes an electric telescopic rod 91 and a pusher plate 92. The fixed end of the electric telescopic rod 91 is fixedly installed on the storage rack 90, and the pusher plate 92 is fixedly installed on the movable end of the electric telescopic rod 91.
