Detailed implementation manners

[0019] The present invention will be further described below in conjunction with the accompanying drawings and implementation manners.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , where Figure 1 is the main structure perspective view of the die-casting device and method for column cap production provided by the present invention; Figure 1 ; Figure 2 is the schematic structure diagram of the swing arm provided by the present invention; Figure 1 ; Figure 3 is the schematic structure diagram of the swing arm provided by the present invention; Figure 2 ; Figure 4 is Figure 3 the schematic enlarged structure diagram of A shown; Figure 5 is the main structure perspective view of the die-casting device and method for column cap production provided by the present invention; Figure 2 ; Figure 6 is Figure 5 the schematic enlarged structure diagram of B shown.

[0021] In the specific implementation process, as Figures 1 - 6As shown in the figure, it includes a die-casting machine body 1. A swing arm 2 is arranged on one side of the die-casting machine body 1. A support platform 3 is installed on the swing arm 2. A support column 5 driven by a first motor 4 is movably arranged on the support platform 3. When clamping the column cap, the first motor 4 can be started to drive the rotating seat 6 to rotate to a position horizontal to the swing arm 2. After clamping the column cap, the first motor 4 is started to move the rotating seat 6 to a vertical position, reducing the rotation radius of the rotating seat 6 on the swing arm 2 and reducing its floor space. A support frame 20 is arranged on one side of the die-casting machine body 1. A support shaft 21 is movably arranged on the support frame 20. The support shaft 21 is fixedly connected to the swing arm 2. A steering gear 22 is installed on the support shaft 21. An electric telescopic rod 23 is arranged on one side of the support frame 20. The output end of the electric telescopic rod 23 is connected to a rack 24. The rack 24 meshes with the steering gear 22. After the moving die of the die-casting machine body 1 completes the die-casting process and resets, at this time, the electric telescopic rod 23 is started to drive the rack 24 to move. Under the driving action of the rack 24 and the steering gear 22, the support shaft 21 rotates to drive the swing arm 2 to rotate.

[0022] A rotating seat 6 is fixed on one side of the support column 5. A first chute 7 is opened on the rotating seat 6. Two support seats 8 are slidably arranged inside the first chute 7. A bidirectional adjustment screw rod 9 is movably arranged inside the first chute 7. Both ends of the bidirectional adjustment screw rod 9 respectively penetrate through the two support seats 8. A second chute 10 is opened on one side of each of the two support seats 8. Two clamping seats 11 are slidably arranged inside the second chute 10. A bidirectional clamping screw rod 12 is movably arranged inside the second chute 10. Both ends of the bidirectional clamping screw rod 12 respectively penetrate through the two clamping seats 11. The bidirectional adjustment screw rod 9 is threadedly connected to the support seat 8, and the bidirectional clamping screw rod 12 is threadedly connected to the clamping seat 11. The bidirectional adjustment screw rod 9 and the bidirectional clamping screw rod 12 are both galvanized. The ejecting device at the moving die of the die-casting machine body 1 is started to eject the column cap. At the same time, the output end of the second motor 18 rotates. Under the driving action of the first bevel gear 17 and the second bevel gear 19, the bidirectional clamping screw rod 12 rotates to drive the two clamping seats 11 to approach each other to firmly fix the edge of the column cap. The opposite surfaces of the clamping seats 11 are respectively set as a convex surface 13 and a concave surface 14. Since most of the edges of the existing column caps during demoulding are circular rings, the two clamping seats 11 respectively set as the convex surface 13 and the concave surface 14 can further reduce the damage to the surface of the column cap when clamping the column cap.

[0023] One end of the bidirectional adjustment screw rod 9 extends out of the rotating seat 6 and is fixed with a hexagonal block 15. The support seat 8 and the rotating seat 6 are fixedly connected by a number of screws. When installing the support seat 8, the wrench can be used to rotate the hexagonal block 15 according to the actual situation (such as the actual production size of the column cap and other factors) to drive the bidirectional adjustment screw rod 9 to rotate. When the bidirectional adjustment screw rod 9 rotates, the distance between the two support seats 8 can be adjusted. After the adjustment is completed, the rotating seat 6 is fixed on the support seat 8. An adjustment sleeve 16 is arranged between the two support seats 8. One end of each of the two bidirectional clamping screw rods 12 extends into the adjustment sleeve 16 and is fixedly connected to it by bolts. After adjusting the distance between the two support seats 8, the relative ends of the two bidirectional clamping screw rods 12 need to be fixedly connected to the adjustment sleeve 16 by bolts.

[0024] One end of one of the bidirectional clamping screw rods 12 extends out of the support seat 8 and is equipped with a first bevel gear 17. A second motor 18 is installed on the support seat 8, and a second bevel gear 19 is installed at the output end of the second motor 18. The first bevel gear 17 meshes with the second bevel gear 19. When the ejecting device at the moving die of the die-casting machine body 1 is started to eject the column cap, at the same time, the output end of the second motor 18 rotates. Under the transmission of the first bevel gear 17 and the second bevel gear 19, the bidirectional clamping screw rod 12 rotates to drive the two clamping seats 11 to move closer to firmly fix the edge of the column cap. At this time, the electric telescopic rod 23 is started to make the swing arm 2 reset.

[0025] On one side of the die-casting machine body 1, there is a frame 25. A chain plate conveyor 37 is installed on the frame 25. Side seats 26 are fixed on both sides of the frame 25. A first lifting rod 27 and a second lifting rod 28 are slidably arranged on the two side seats 26 respectively. A first connecting seat 29 is fixed at the top of the first lifting rod 27. A second connecting seat 30 is fixed at the top of the second lifting rod 28. A receiving table 31 is arranged between the first connecting seat 29 and the second connecting seat 30. The first connecting seat 29 is movably connected to one side of the receiving table 31. A connecting shaft 32 is movably arranged on the other side of the receiving table 31. The connecting shaft 32 is fixedly connected to the second connecting seat 30. A support ring 33 is fixed on one side of the receiving table 31. A scroll spring 34 is arranged inside the support ring 33. One end of the scroll spring 34 is fixed on the inner wall of the support ring 33, and the other end of the scroll spring 34 is fixed on the connecting shaft 32. After the swing arm 2 is reset, the second motor 18 is started to cancel the fixation of the column cap by the clamping seat 11. The column cap falls into the receiving table 31 under the action of gravity. A ejector rod 35 is fixed on the frame 25. The ejector rod 35 is located below the receiving table 31. When the receiving table 31 moves downward, under the action of the ejector rod 35, the receiving table 31 will rotate around the connecting shaft 32. A cylinder 36 is installed on the frame 25. The output end of the cylinder 36 is connected to the bottom of the second lifting rod 28 through a coupling. The cylinder 36 is started to drive the receiving table 31 to move downward. When the receiving table 31 moves downward, under the action of the ejector rod 35, the receiving table 31 rotates, so that the column cap falls onto the chain plate conveyor 37 and is conveyed to other processes. The scroll spring 34 can ensure that the receiving table 31 is reset after discharging.

[0026] The embodiment of the present application also provides a method for a die-casting device for producing column caps. The method includes the following steps: After the moving die of the die-casting machine body 1 completes the die-casting process and resets, at this time, the electric telescopic rod 23 is started to drive the rack 24 to move. Under the driving action of the rack 24 and the steering gear 22, the support shaft 21 rotates to drive the swing arm 2 to adjust from a horizontal posture relative to the die-casting machine body 1 to a vertical posture. At this time, the support seat 8 is located on one side of the moving die of the die-casting machine body 1; Start the first motor 4 to drive the rotating seat 6 to rotate to a position horizontal with the swing arm 2; Start the ejecting device at the moving die of the die-casting machine body 1 to eject the column cap. At the same time, the output end of the second motor 18 rotates. Under the driving action of the first bevel gear 17 and the second bevel gear 19, the bidirectional clamping lead screw 12 rotates to drive the two clamping seats 11 to approach each other to firmly fix the edge of the column cap. At this time, start the electric telescopic rod 23 to reset the swing arm 2; After the swing arm 2 is reset, start the second motor 18 to cancel the fixation of the column cap by the clamping seat 11. The column cap falls into the receiving table 31 under the action of gravity; Finally, the starting cylinder 36 drives the material receiving table 31 to move downward. When the material receiving table 31 moves downward, under the action of the ejector rod 35, the material receiving table 31 rotates, causing the column cap to fall onto the chain plate conveyor 37 and be conveyed to other processes.
