[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a pneumatic plate stabilizing device for the upper die of an automobile mold as shown in Figure 1 - Figure 6 . It includes an upper die 1, which is mainly used for forming automobile molds and is prior art, so no more description will be given here. Demolding holes 2 for facilitating demolding are respectively penetrated through both ends of the upper die 1. U-shaped plates 3 are fixedly provided at both ends of the upper die 1. A first-stage plugging block 4 for sealing the demolding holes 2 is movably arranged inside the U-shaped plates 3. The demolding holes 2 and the first-stage plugging block 4 have the same shape. A second-stage plugging block 5 for secondarily plugging the demolding holes 2 is fixedly provided at one end of the first-stage plugging block 4 away from the upper die 1 to secondarily plug the demolding holes 2 and ensure the pressure inside the upper die 1.

[0028] A first electric cylinder 6 is fixedly provided at one end of the U-shaped plate 3 away from the upper die 1. The output end of the first electric cylinder 6 is fixedly provided with a moving block 8. One end of the moving block 8 is fixedly connected to one end of the second-stage plugging block 5.

[0029] Through the arrangement of the first-stage plugging block 4 and the demolding holes 2, when forming automobile parts, during demolding, holes are generated inside the upper die 1, and air enters the inside of the upper die 1, changing the contact situation between the product and the upper die 1, so as to prevent the difficulty of demolding caused by negative pressure between the upper die 1 and the product, and thus facilitate the demolding operation.

[0030] Two guide rods 16 are fixedly provided at one end of the second-stage plugging block 5 away from the upper die 1. The guide rods 16 movably pass through the U-shaped plates 3 to strengthen the connection strength of the second-stage plugging block 5 through the guide rods 16.

[0031] One end of the U-shaped plate 3 corresponding to the first electric cylinder 6 is fixedly provided with a second electric cylinder 7. Both the first electric cylinder 6 and the second electric cylinder 7 are prior arts and will not be described in detail here. The output end of the second electric cylinder 7 is fixedly provided with a triangular block 11. Both ends of the triangular block 11 are fixedly provided with inclined plates 12. One end of the moving block 8 is provided with a locking groove 9. A locking block 10 is movably arranged inside the locking groove 9. An inclined groove 13 is arranged inside the locking block 10. The inclined plates 12 slide inside the inclined groove 13.

[0032] Through the setting of the locking block 10, when the primary plugging block 4 plugs the demolding hole 2, the stability of the primary plugging block 4 is improved, the service strength of the primary plugging block 4 is ensured, and the use of the upper mold 1 is prevented from being affected when forming products.

[0033] Both ends of the locking block 10 are fixedly provided with limiting rods 15. Both ends of the moving block 8 are fixedly provided with vertical plates 14. A rectangular groove for the up and down sliding of the limiting rod 15 is arranged on one side of the vertical plate 14 corresponding to the limiting rod 15. Through the setting of the vertical plate 14 and the limiting rod 15, the moving direction of the locking block 10 is shown.

[0034] A plurality of vibration transmission plates 17 are fixedly arranged at both ends of the upper mold 1. Vibration plates 18 are fixedly arranged at both ends of the secondary plugging block 5. An inclined surface 19 is arranged on one side of the vibration transmission plate 17 close to the vibration plate 18. Through the setting of the inclined surface 19, when the position of the vibration plate 19 is farther from the upper mold 1, the pressure between the vibration plate 18 and the vibration transmission plate 17 is higher, so as to gradually increase the vibration intensity;

[0035] When the primary plugging block 4 is inside the demolding hole 2, the vibration plate 18 only contacts the smooth inclined surface 19 of the vibration transmission plate 17. A plurality of semi-circular rods 20 are fixedly arranged on the mutually close surfaces of the vibration transmission plate 17 and the vibration plate 18. When the primary plugging block 4 is not inside the demolding hole 2, the vibration plate 18 contacts the vibration transmission plate 17 through the semi-circular rods 20.

[0036] Through the setting of the vibration plate 18 and the vibration transmission plate 17, when the product fails to demold by changing the air negative pressure, it is prevented that the product fails to be completely demolded and drops. Then, through the forced vibration method, the product is processed for falling off here. When demolding by negative pressure, vibration demolding is automatically carried out in time;

[0037] Through the setting of the first electric cylinder 6, after successful demolding by negative pressure, when it is not necessary to use vibration for secondary demolding, only the stroke of the first electric cylinder needs to be controlled to control the demolding method. Its demolding method has high selectivity and high practicability.

[0038] Working principle: The operator controls the first electric cylinder 6 to work, so that the first electric cylinder 6 drives the moving block 8 to move towards the upper mold 1, and then the moving block 8 drives, and then the moving block 8 drives the secondary plugging block 5 to move. The secondary plugging block 5 drives the primary plugging block 4 to move, so that the primary plugging block 4 blocks the demolding hole 2, and the secondary plugging block 5 blocks the edge of the demolding hole 2 for double sealing. Then, the second electric cylinder 7 is started, so that the second electric cylinder 7 drives the triangular block 11 to move, and then the triangular block 11 drives the inclined plate 12 to move. Then, through the cooperation of the inclined plate 12 and the inclined groove 13, the inclined plate 12 drives the locking block 10 to move towards the locking groove 9, so that the locking block 10 completely enters the inside of the locking groove 9 to increase the plugging strength of the primary plugging block 4, and then the product is formed;

[0039] After the product is formed, first control the second electric cylinder 7 to drive the triangular block 11 away from the upper mold 1, so that the triangular block 11 drives the inclined plate 12 to move. The inclined plate 12 then drives the locking block 10 to disengage from the inside of the locking groove 9 through the inclined groove 13. Then, due to the arrangement of the limiting rod 15 and the vertical plate 14, the locking block 10 can only move up and down, so that the locking block 10 is always directly above the locking groove 9, and then the moving block 8 is unlocked. Control the first electric cylinder 6 so that the first electric cylinder 6 drives the moving block 8 away from the upper mold 1, and the moving block 8 drives the secondary plugging block 5 to move, so that the primary plugging block 4 disengages from the demolding hole 2, which is convenient for the operator to perform the demolding operation on the product;

[0040] When the negative pressure does not drop the product, just control the first electric cylinder 6 to continue working, drive the secondary plugging block 5 to move away from the upper mold 1, so that the secondary plugging block 5 drives the two vibrating plates 18 to move, and then the vibrating plates 18 contact and move the vibration transmitting plate 17. Then, through the mutual contact and sudden fall of the semi-circular rods 20 on the vibrating plates 18 and the vibration transmitting plate 17, the vibration effect is completed, and the vibration force is conducted to the upper mold 1 through the vibration transmitting plate 17 for vibration demolding.
