DETAILED DESCRIPTION

[0025] Reference Figure 1-Figure 4 A forging device capable of automatically ejecting parts comprises a processing table 1, a lower die 2, a hydraulic cylinder 4 and an upper die 5. The hydraulic cylinder 4 is coaxially arranged above the lower die 2 through a mounting frame 3. The output end of the hydraulic cylinder 4 is coaxially fixedly connected with the upper die 5. A connecting cavity 13 is arranged in the lower die 2. A through hole 12 is provided at the bottom of the lower die 2. A plurality of jacks 11 are evenly provided at one end of the lower die 2 close to the through hole 12. An automatic ejection mechanism is arranged at the bottom of the lower die 2. The automatic ejection mechanism is used to eject the preformed rough parts in the lower die 2.

[0026] The automatic ejection mechanism includes a driving motor 22, a driving gear 23, a turntable 16, a plurality of fixed rods 18, a plurality of limit blocks 19, a plurality of telescopic rods 20 and a plurality of insertion rods 21. The driving motor 22, the driving gear 23, the turntable 16 and the plurality of telescopic rods 20 are all arranged in the installation cavity. The output end of the driving motor 22 is coaxially fixedly connected with the driving gear 23. The outer wall of the turntable 16 is provided with teeth meshing with the driving gear 23. The turntable 16 is coaxially arranged in the installation cavity. The turntable 16 is evenly provided with a plurality of arc holes 17, and the plurality of arc holes 17 are distributed on the turntable 16 in a circular array. The driving gear 23 is driven by the output end of the driving motor 22 to cooperate with the teeth on the outer wall of the turntable 16 to realize the rotation of the turntable 16. When the turntable 16 rotates, the arc holes 17 will cooperate with the slide bar and the limit block 19 on the telescopic rod 20.

[0027] A plurality of fixed rods 18 are distributed on the turntable 16 in a circular array, and a slide groove is provided on the fixed rod 18. The telescopic rod 20 is arranged in the slide groove. The telescopic rod 20 is fixedly connected to the limit block 19 through a slide rod. The slide rod is arranged in the arc hole 17. The telescopic rod 20 and the limit block 19 are respectively arranged on both sides of the turntable 16. One end of the telescopic rod 20 away from the fixed rod 18 is fixedly connected to the insertion rod 21. The arc hole 17 cooperates with the slide rod and the limit block 19 on the telescopic rod 20, so that the telescopic rod 20 contracts in the slide groove in the fixed rod 18, so that the insertion rod 21 is separated from the insertion hole 11 in the lower mold 2.

[0028] The automatic ejection mechanism also includes an electric push rod 15 and a base 14. The electric push rod 15 is coaxially fixedly arranged below the through hole 12. The output end of the electric push rod 15 is coaxially fixedly connected to the base 14. An installation cavity is provided in the base 14. The base 14 is pushed by the output end of the electric push rod 15 to automatically eject the preformed rough parts in the lower mold 2 from the lower mold 2. The staff does not need to remove the lower mold 2 from the processing table 1. The operation is simple and convenient, which reduces the labor intensity of the staff.

[0029] Reference Figure 1 and Figure 4 The connecting cavity 13 is connected to a cooling mechanism, and the cooling mechanism is used to perform heat exchange on the preformed wool accessories in the lower mold 2 to accelerate the molding of the preformed wool accessories;

[0030] The cooling mechanism includes a water pump 6 and a cold water tank 7. The water pump 6 is connected to the cold water tank 7 through a pumping pipe. The water pump 6 is connected to the connecting cavity 13 of the lower mold 2 through a water supply pipe. The end of the connecting cavity 13 away from the water supply pipe is connected to the water storage tank 8 through a drain pipe 9. The cold water in the cold water tank 7 is sucked into the connecting cavity 13 in the lower mold 2 by the water pump 6. The cold water entering the connecting cavity 13 finally enters the water storage tank 8 through the drain pipe 9. Due to the continuous delivery of cold water by the water pump 6, heat is exchanged with the preformed rough accessories in the lower mold 2, thereby accelerating the cooling of the preformed rough accessories.

[0031] Reference Figure 1 and Figure 4 The connecting cavity 13 is evenly wound in the lower mold 2, and the connecting cavity 13 is arranged at one end close to the inner wall of the lower mold 2. The effect of this arrangement is to facilitate the continuous circulation of cold water in the connecting cavity 13, and continuously exchange heat for the preformed wool accessories in the lower mold 2.

[0032] Reference Figure 3The width of the limit block 19 is greater than the width of the arc hole 17. The effect of this arrangement is that when the turntable 16 rotates, the arc hole 17 rotates with the turntable 16. Since the width of the limit block 19 is greater than the width of the arc hole 17, the slide bar is restricted in the arc hole 17. As the turntable 16 rotates, the telescopic rod 20 is telescoped in the slide groove of the fixed rod 18. A plurality of support legs 10 for supporting the processing table 1 are provided at the bottom of the processing table 1.

[0033] The working principle of the utility model is as follows:

[0034] The cold water in the cold water tank 7 is sucked into the connecting cavity 13 in the lower mold 2 by the water pump 6. The cold water in the connecting cavity 13 finally enters the water storage tank 8 through the drain pipe 9. Due to the continuous delivery of the cold water by the water pump 6, the cold water continues to flow in the connecting cavity 13, and heat is exchanged with the preformed rough parts in the lower mold 2, thereby accelerating the cooling of the preformed rough parts.

[0035] When it is necessary to lift the preformed blank in the lower mold 2, the output end of the driving motor 22 drives the active gear 23 to cooperate with the teeth on the outer wall of the turntable 16 to realize the rotation of the turntable 16. When the turntable 16 rotates, the arc hole 17 will cooperate with the slide bar and the limit block 19 on the telescopic rod 20, so that the telescopic rod 20 will shrink in the slide groove in the fixed rod 18, so that the insertion rod 21 will be separated from the socket 11 in the lower mold 2, and then the base 14 will be pushed by the output end of the electric push rod 15 to automatically eject the preformed blank in the lower mold 2.
