[0022] 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.
[0023] As Figures 1 to 5 shown, the present utility model provides a forging die for a fire hydrant, including an upper die 1. A fixed frame 4 is fixedly arranged on the top surface of the upper die 1. A motor 3 is fixedly arranged on the top surface of the fixed frame 4. The end of the main shaft of the motor 3 is fixedly provided with a gear disc 5. The outer side of the gear disc 5 is meshed with a small gear 6. The outer side of the small gear 6 is fixedly connected with a lead screw 7. A clamping plate 9 is slidably arranged on the outer side of the lead screw 7. The other end of the clamping plate 9 is interference-connected with a side slider 10. The outer side of the side slider 10 is slidably arranged with a fire hydrant body 15, and the fire hydrant body 15 is fitted with the upper die 1. By driving the slider in the die to slide out by the motor 3, it is ensured that the quality of the product will not be affected during the production process, which not only ensures the quality of the final product, avoids the waste of raw materials caused by defective products, but also avoids the extension of the production cycle.
[0024] Specifically, a fixed block 8 is fixedly arranged on the top surface of the upper die 1, and the lead screw 7 rotates inside the fixed block 8. The function of the fixed block 8 is to support the lead screw 7 and limit it, and at the same time ensure its normal operation.
[0025] Furthermore, an upper slider 13 is slidably arranged inside one side of the fire hydrant body 15, and the side slider 10 is in contact with the upper slider 13. Since the waterway inside the fire hydrant body 15 cannot directly meet the requirements of upper and lower die opening, multiple sliders need to be set to ensure the normal production of the fire hydrant body 15.
[0026] Furthermore, a lower slider 14 is slidably arranged on the other side of the fire hydrant body 15, and the lower slider 14 is in contact with the upper slider 13. The side slider 10, the upper slider 13 and the lower slider 14 form a sealed whole, ensuring the formation of the water path inside the fire hydrant body 15 and preventing the problem of blocked water path.
[0027] It should be noted that a side slider 10 is fixedly connected to the outer side of the clamping plate 9, and a lower mold 2 is slidably arranged on the outer side of the side slider 10. The lower mold 2 is fitted with the fire hydrant body 15. When the clamping plate 9 moves, it drives the side slider 10 to slide out from the inside of the lower mold 2, facilitating the subsequent mechanical operation.
[0028] It should be noted that a hydraulic telescopic device 11 is fixedly arranged on the bottom surface of the lower mold 2, and a push block 12 is fixedly arranged at the end of the main shaft of the hydraulic telescopic device 11. After the sliding plate 16 is pulled out, the hydraulic telescopic device 11 pushes the push block 12, and the push block 12 pushes the fire hydrant body 15, thus completing the demoulding action of the fire hydrant body 15.
[0029] It should be introduced that a cooling water path is arranged inside the lower mold 2, and the water path spreads throughout the inside of the lower mold 2. A large amount of high temperature is generated during the production of the mold, and the function of the water path is to cool the product, thereby accelerating the shaping of the product. At the same time, uneven cooling will also cause the product to deform. Therefore, cooling water paths are arranged on the front and rear brightness and both sides of the fire hydrant body 15.
[0030] Among them, the motor 3 and the hydraulic telescopic device 11 are prior arts and will not be elaborated. At the same time, the present utility model also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated. The "front, rear, left, and right" perspectives of this device are based on Figure 1 the direction shown in the drawing.
[0031] Working principle and process:
[0032] When using a fire hydrant forging die, first, turn on the switch of the motor 3 on the top surface of the fixing frame 4 to start working. When the motor 3 rotates, it drives the gear disc 5 at the end of the main shaft to start rotating. The gear disc 5 then drives the small gear 6 to rotate. On the other side of the small gear 6, there is a screw rod 7 fixedly connected. Therefore, when the small gear 6 rotates, the screw rod 7 also rotates accordingly. When the screw rod 7 rotates, it drives the clamping plate 9 to slide. On the other side of the clamping plate 9, there is a side slider 10 fixedly connected. When the clamping plate 9 moves, it simultaneously pulls out the side slider 10 from the inside of the fire hydrant body 15, thus completing the production of the waterway inside the fire hydrant body 15. Here, the motor 3 is fixedly arranged on the top surface of the upper die 1 through the fixing frame 4. Since the upper die 1 is a moving die in the die, generally, the main structure is installed on the moving die. At the same time, the function of the fixing block 8 is to support the screw rod 7 and limit it, while ensuring its normal operation. There are upper sliders 13 and lower sliders 14 slidably arranged at the upper and lower ends of the fire hydrant body 15. The upper sliders 13 and lower sliders 14 are also for the formation and production of the waterway inside the fire hydrant body 15. When the clamping plate 9 moves, in addition to pulling out the side slider 10, it also drives the sliding plate 16. After the sliding plate 16 slides out, turn on the hydraulic telescopic device 11 on the bottom surface of the lower die 2. The hydraulic telescopic device 11 pushes the push block 12, and the push block 12 simultaneously pushes the fire hydrant body 15, pushing the fire hydrant body 15 out of the inside of the die, thus completing the whole production process. The utility model drives the sliding out of the slider in the die through the motor 3, ensuring that it will not affect the quality of the product during the production process, not only ensuring the quality of the final product, avoiding the waste of raw materials caused by defective products, but also avoiding the extension of the production cycle and the compensation caused by not completing the production amount within the fixed time.
[0033] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
