Description

Technical Field

[0001] This invention belongs to the field of molds, specifically a forging mold for producing fan shafts. Background Technology

[0002] A fan is a type of driven fluid machinery that works by inputting mechanical energy to increase the pressure of gas and then expel it from other machinery.

[0003] The operation of a fan is inseparable from its shaft. The main shaft of a fan is a component that transmits torque and is usually made of stainless steel.

[0004] The processing of fan shafts usually involves molds. The use of molds generally involves pouring molten iron into the mold, waiting for it to cool, demolding it, and then forging it to produce the finished fan shaft. However, with existing molds, a lot of iron filings will appear inside the mold after demolding. The presence of these iron filings will affect the next mold processing.

[0005] Therefore, the present invention provides a forging die for producing a fan shaft. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A forging mold for producing a fan shaft, comprising a first base; four symmetrically arranged electric telescopic rods are fixedly connected to the four corners of the bottom of the first base; a second base is fixedly connected to the end of each electric telescopic rod; a first water tank is fixedly connected to the bottom of the second base; a top rod is connected to the top of the first water tank; the top rod extends through the middle of the second base to the bottom of the first base; multiple water outlet holes are opened in the middle of the top rod; the water outlet holes are arranged in an array; two symmetrically arranged support rods are fixedly connected to the inner side wall of the top rod; the symmetrically arranged support rods... A fixing block is fixedly connected to the middle of the mold; an auger is rotatably connected to the top of the fixing block; the length of the auger extends to the position of the water outlet; a top block is fixedly connected to the top of the top rod; the top block and the first base slide together; the top block extends into the interior of the mold; a third base is fixedly connected to the bottom of the first water tank. With this structure, not only can the mold be removed more easily, but the iron filings generated inside the mold after the finished product is ejected can also be sprayed and washed in time. At the same time as spraying and washing, the interior of the mold can be cooled down quickly, thereby cleaning the interior of the mold and reducing the impact of falling iron filings on the next molding.

[0008] Preferably, the top of the top block is fixed with two sets of symmetrically arranged plastic plates; the top of the second base has two symmetrically arranged through holes; the top of the first water tank is connected to two first water pipes; and both first water pipes extend to the top of the second base through the through holes; a grid plate is fixed to the water outlet of the first water pipe; and a first conical cylinder is fixed to the end of the first water pipe. With this structure, the sliding joint between the first water tank and the first base can be fixed by plastic. After the mold cools down, the plastic cup blocked inside the sliding joint can be torn by activating the electric telescopic rod, thus preventing molten iron from leaking out along the sliding joint after being poured into the mold.

[0009] Preferably, the top of the third base is fixedly connected to two symmetrical second water tanks; the side walls of the second water tanks are connected to second water pipes; the second water pipes are directly opposite the top of the second base; the outlet of the second water pipes is fixedly connected to a perforated plate. With this structure, the electric telescopic rod can be lubricated at any time, thereby reducing the friction generated when the electric telescopic rod is working and increasing the service life of the electric telescopic rod.

[0010] Preferably, a second conical cylinder is fixedly connected to the end of the second water pipe; an annular baffle is fixedly connected to the inner wall of the second conical cylinder near the end. With this structure, the blocked lubricating fluid can be re-flowed into the interior of the second water pipe, thereby reducing the waste of lubricating fluid.

[0011] Preferably, the top of the second base has multiple guide channels; the multiple guide channels are equidistantly distributed, so this structure can prevent excessive accumulation of waste liquid on the top of the second base, which could lead to equipment damage.

[0012] Preferably, the bottom of the second base is provided with a groove; the groove is located below the multiple guide channels; the opposite surfaces of the groove are provided with sliding grooves; a slider is slidably connected inside the sliding groove; a liquid collection box is fixed between two sliding grooves. With this structure, waste liquid can be collected and treated uniformly, reducing the environmental pollution caused by waste liquid turbulence.

[0013] Preferably, the second base has support plates fixedly connected to both sides of the second water pipe; the end of the support plate is fixedly connected to a collar; the collar is sleeved on the outside of the second water pipe. This structure can protect the second water pipe and prevent the lubricant remaining inside the second water pipe from flowing erratically.

[0014] Preferably, a guide plate is fixedly connected to the end of the chute; the guide plates are symmetrically arranged. This structure allows the liquid collection box to slide more conveniently and quickly to the bottom of the second base, thereby reducing the problem of falling off due to unstable fixing.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The forging die for producing a fan shaft as described in this invention uses coolant sprayed into the interior of the ejector rod, where the end of the ejector rod is inside the die, and the water outlet is also inside the die. The coolant is sprayed into the die through the water outlet. When the coolant passes through the auger, the auger is driven by the coolant, causing it to rotate. This rotation of the auger causes a portion of the coolant to rotate as well, giving the coolant a force that helps to eject the die more easily. It also allows for timely cleaning of iron filings generated inside the die after the finished product is ejected. Simultaneously, the cleaning process rapidly cools the interior of the die, thus cleaning the interior and reducing the impact of falling iron filings on the next casting process.

[0017] 2. The forging mold for producing a fan shaft described in this invention involves rapidly melting a plastic plate. The molten plastic liquid falls down along the sliding seam. At this time, by activating the water pump inside the first water tank, the liquid is sprayed out through the end of the first water pipe. Coolant is sprayed onto the flowing plastic liquid, allowing it to quickly solidify. This structure allows the sliding seam between the first water tank and the first base to be fixed by the plastic. After the mold has cooled down, the plastic cup blocking the sliding seam can be torn apart by activating the electric telescopic rod. This prevents molten iron from leaking out along the sliding seam after being poured into the mold. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 7As shown in the embodiment of the present invention, a forging die for producing a fan shaft includes a first base 1; four symmetrically arranged electric telescopic rods 2 are fixedly connected to the four corners of the bottom of the first base 1; a second base 12 is fixedly connected to the end of each electric telescopic rod 2; a first water tank 19 is fixedly connected to the bottom of the second base 12; a top rod 13 is connected to the top of the first water tank 19; the top rod 13 extends through the middle of the second base 12 to the bottom of the first base 1; a plurality of water outlet holes 14 are provided in the middle of the top rod 13; the water outlet holes 14 are arranged in an array. The inner wall of the top rod 13 is fixed with two symmetrically arranged support rods 15; a fixing block 16 is fixedly connected to the middle of the symmetrically arranged support rods 15; an auger 17 is rotatably connected to the top of the fixing block 16; the length of the auger 17 extends to the position of the water outlet 14; a top block 18 is fixedly connected to the top of the top rod 13; the top block 18 and the first base 1 are in sliding fit; the top block 18 extends into the interior of the mold; a third base 110 is fixedly connected to the bottom of the first water tank 19. During operation, when the mold processing is completed, the four corner electric motors can be activated. When the telescopic rod 2 retracts downwards, the stationary push rod 13 protrudes relatively. Simultaneously, the push rod 13 moves the push block 18 upwards, ejecting the finished mold. At the same time, coolant is filled into the first water tank 19. Then, the water pump inside the first water tank 19 is activated. Since the push rod 13 is hollow, coolant is sprayed into its interior. At this point, the end of the push rod 13 is inside the mold, and the water outlet 14 is also inside the mold. The coolant is then sprayed through the water outlet 14. When the coolant is sprayed into the mold, it rotates as it passes through the auger 17. This rotation causes some of the coolant to rotate as well, creating a force that propels the coolant outwards. This structure not only facilitates mold ejection but also allows for the timely cleaning of iron filings generated inside the mold after the finished product is ejected. Simultaneously, the cleaning process rapidly cools the mold's interior, effectively cleaning the inside and reducing the impact of falling iron filings on subsequent casting processes.

[0029] like Figure 2As shown, two sets of symmetrically arranged plastic plates 21 are fixed to the top of the top block 18; two symmetrically arranged through holes 22 are opened on the top of the second base 12; two first water pipes 23 are connected to the top of the first water tank 19; and both first water pipes 23 extend to the top of the second base 12 through the through holes 22; a mesh plate 25 is fixed to the water outlet of the first water pipe 23; a first conical cylinder 24 is fixed to the end of the first water pipe 23. During operation, since the top block 18 and the first base 1 are in a sliding fit, a very small slip gap will be generated in the middle; these small slip gaps will cause the molten iron poured into the mold to flow out. At this time, by installing plastic plates 21 on the top of the top block 18, and at the same time, the first... The top of the water tank 19 is connected to two first water pipes 23. When molten iron is poured into the mold, it will first come into contact with the plastic plate 21. At this time, due to the material of the plastic plate 21, it will be melted quickly. The molten plastic liquid will fall down along the sliding joint. At this time, by activating the water pump inside the first water tank 19, the liquid is sprayed out through the end of the first water pipe 23. The coolant is sprayed onto the flowing plastic liquid, which will make the plastic liquid quickly solidify. Through this structure, the sliding joint between the first water tank 19 and the first base 1 can be fixed by the plastic. After the mold has cooled down, the plastic cup blocked inside the sliding joint can be torn by activating the electric telescopic rod 2. This can prevent the molten iron from leaking out along the sliding joint after being poured into the mold.

[0030] like Figures 1 to 3 As shown, two symmetrical second water tanks 3 are fixedly connected to the top of the third base 110; the side walls of the second water tanks 3 are connected to second water pipes 31; the second water pipes 31 are directly opposite the top of the second base 12; a perforated plate 32 is fixedly connected to the outlet of the second water pipes 31. During operation, frequent starting of the electric telescopic rod 2 will cause some wear on the electric telescopic rod 2. At this time, by filling the inside of the second water tanks 3 with lubricating fluid, and then starting the water pump placed inside the second water tanks 3, the lubricating fluid is sprayed onto the surface of the electric telescopic rod 2 along the second water pipes 31. Through this structure, the electric telescopic rod 2 can be lubricated at any time, thereby reducing the friction generated by the electric telescopic rod 2 during operation and increasing the service life of the electric telescopic rod 2.

[0031] like Figure 3As shown, a second conical cylinder 4 is fixedly connected to the end of the second water pipe 31; an annular baffle 41 is fixedly connected to the inner wall of the second conical cylinder 4 near the end. During operation, when the lubricating fluid is sprayed out along the second water pipe 31, the water pump placed in the second water tank 3 is turned off. At this time, the lubricating fluid will stop spraying out. However, the lubricating fluid has a certain viscosity and will not stop immediately. At this time, by installing the second conical cylinder 4 at the end of the second water pipe 31 and then installing the annular baffle 41 at the outlet of the second conical cylinder 4, the lubricating fluid that drips out afterward can be blocked by the annular baffle 41 inside the second conical cylinder 4. Through this structure, the blocked lubricating fluid can be backflowed into the second water pipe 31, thereby reducing the waste of lubricating fluid.

[0032] like Figures 1 to 6 As shown, the top of the second base 12 has multiple guide channels 5. The multiple guide channels 5 are equidistantly distributed. During operation, when the lubricating fluid is sprayed onto the surface of the electric telescopic rod 2, and when the coolant sprayed from the first water pipe 23 and the top rod 13 falls, the waste liquid can flow into the guide channels 5 and then flow out of the top of the second base 12. Because there are many devices on the top of the second base 12, this structure can prevent the waste liquid from accumulating too much on the top of the second base 12, which could lead to equipment damage.

[0033] like Figure 5 As shown, the bottom of the second base 12 is provided with a groove 6; the groove 6 is located below the multiple guide channels 5; the opposite surfaces of the groove 6 are provided with sliding grooves 61; a slider 62 is slidably connected inside the sliding groove 61; a liquid collection box 63 is fixedly connected between two sliding grooves 61. During operation, when the waste liquid flows to the outside through the guide channel 5, it can flow into the interior of the liquid collection box 63 by slidingly connecting it to the bottom of the second base 12. With this structure, the waste liquid can be collected and treated uniformly, reducing the environmental pollution caused by the turbulent flow of waste liquid.

[0034] like Figure 5 As shown, the second base 12 has support plates 7 fixedly connected to both sides of the second water pipe 31; the end of the support plate 7 is fixedly connected to a collar 71; the collar 71 is sleeved on the outside of the second water pipe 31. When the second water pipe 31 is not working, it is often placed on both sides of the equipment, which makes it easy to be damaged by external forces. At this time, the second water pipe 31 when not working can be sleeved inside the auger 17. Through this structure, the second water pipe 31 can be protected, and at the same time, the residual lubricating fluid inside the second water pipe 31 can be prevented from flowing erratically.

[0035] like Figures 1 to 6As shown, a guide plate 8 is fixedly connected to the end of the slide 61. The guide plates 8 are symmetrically arranged. During operation, the liquid collection box 63 needs to be slidably connected to the bottom of the second base 12. If it is not aligned, it may become unstable and fall off, or it may not be able to slide into the bottom of the second base 12. By installing guide plates 8 on both sides, the liquid collection box 63 can be guided. With this structure, the liquid collection box 63 can slide to the bottom of the second base 12 more conveniently and quickly, thereby reducing the problem of falling off due to unstable fixation.

[0036] like Figures 1 to 6 As shown, a handle 9 is fixedly attached to the side wall of the liquid collection box 63; multiple anti-slip particles 91 are fixedly attached to the middle of the handle 9. During operation, by installing the handle 9 on the side wall of the liquid collection box 63, it is easier to pull out and push the liquid collection box 63. Subsequently, by installing anti-slip particles 91 on the surface of the handle 9, the friction force when pulling the handle 9 can be increased. With this structure, not only can the waste liquid be treated uniformly more conveniently, but it can also prevent the waste liquid from spilling due to insufficient friction between the hand and the handle 9.

[0037] During operation, when the mold processing is complete, the four corner electric telescopic rods 2 can be activated. The electric telescopic rods 2 retract downwards, causing the stationary ejector rod 13 to protrude relatively. Simultaneously, the ejector rod 13 drives the ejector block 18 to move upwards, allowing the processed mold to be ejected. Simultaneously, coolant is filled into the first water tank 19. Then, the water pump placed inside the first water tank 19 is activated. At this time, the ejector rod 13 is hollow, and coolant is sprayed into its interior. The end of the ejector rod 13 is inside the mold, and simultaneously... Water hole 14 is also inside the mold. At this time, the coolant is sprayed into the mold through water outlet hole 14. When the coolant passes through auger 17, auger 17 will be driven by the coolant, thus generating rotation. At this time, the rotation of auger 17 will drive a part of the coolant to rotate together, thus giving the coolant a force to be thrown out. Since the top block 18 and the first base 1 are in sliding fit, a very small slip gap will be generated in the middle. These small slip gaps will cause the molten iron poured into the mold to flow out. At this time, by installing a plastic plate 21 on the top of the top block 18.Simultaneously, two first water pipes 23 are connected to the top of the first water tank 19. When molten iron is poured into the mold, it will first come into contact with the plastic plate 21. Due to the material of the plastic plate 21, it will be melted quickly. The molten plastic liquid will then fall down along the sliding seam. At this time, by activating the water pump inside the first water tank 19, the liquid is sprayed out through the end of the first water pipe 23. The coolant sprayed onto the flowing plastic liquid will allow the plastic liquid to quickly solidify. Frequent operation of the electric telescopic rod 2 will cause some wear to the electric telescopic rod 2. At this time, lubricant is filled inside the second water tank 3, and then the water pump placed inside the second water tank 3 is activated to allow the lubricant to be sprayed onto the surface of the electric telescopic rod 2 along the second water pipe 31. After the lubricant is sprayed out along the second water pipe 31, the water pump placed inside the second water tank 3 is turned off. At this time, the lubricant will stop spraying. However, the lubricant has a certain viscosity and will not stop immediately. At this time, a second conical cylinder 4 is installed at the end of the second water pipe 31, and then a water outlet of the second conical cylinder 4 is installed... An annular baffle 41 is installed to block the subsequent dripping lubricant inside the second conical cylinder 4. When the lubricant is sprayed onto the surface of the electric telescopic rod 2, and when the coolant sprayed from the first water pipe 23 and the top rod 13 falls, the waste liquid can flow into the guide channel 5 and then out of the top of the second base 12. Because there are many devices on the top of the second base 12, when the waste liquid flows to the outside through the guide channel 5, it can be slidably connected to the bottom of the second base 12 by a collection box 63, allowing the waste liquid to flow into the inside of the collection box 63. When the second water pipe 31 is not working, it is often placed on both sides of the equipment, which makes it easy to be damaged by external forces. At this time, the second water pipe 31 can be fitted inside the auger 17 when it is not working. The collection box 63 needs to be slidably connected to the bottom of the second base 12 frequently. If it is not aligned, it may be unstable and fall off, or it may not slide into the bottom of the second base 12. By installing guide plates 8 on both sides, the collection box 63 can be guided.
