Description

Technical Field

[0001] This invention relates to the field of gear forging equipment technology, specifically to a precision forging die for mechanical transmission gears. Background Technology

[0002] Mechanical transmission gears are precision parts widely used to transmit precise motion and power. They require high precision, high strength, and high wear resistance. Their processing methods include machining, plastic precision forging, pressure processing, and powder metallurgy forming. Among them, the hot precision forging process for transmission gears has many advantages such as high production efficiency, high material utilization, enhanced gear strength, and energy saving. It is an advanced net forming technology.

[0003] In particular, after the gear is die-cast with high precision, the contact surface between the gear and its surroundings is too large. If a conventional ejector rod is used at this time, the contact surface between the ejector rod and the gear will generate excessive pressure, causing slight deformation at the stress position of the gear and affecting the precision of the gear. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a mechanical transmission gear precision forging forming mold, including a base, a slide rail fixedly connected to the top of the base, a slide frame slidably connected to the inner wall of the slide rail, and an upper mold fixedly connected to the bottom of the slide frame;

[0005] The pneumatic mechanism includes a lower mold, a pneumatic cylinder and piston ring for fixing and supporting the lower mold, and a discharge assembly for discharging the finished product inside the lower mold.

[0006] The top of the base is fixedly connected to the bottom of the air cylinder, the inner wall of the air cylinder is slidably connected to the outer wall of the piston ring, and the inner wall of the piston ring is fixedly connected to the outer wall of the lower mold.

[0007] Preferably, the material discharge assembly includes a gear base plate fixedly connected to the inner wall of the lower mold. The side wall of the gear base plate has several mounting through holes. The inner wall of the several mounting through holes is fixedly connected to a mounting plate. The inner wall of the mounting plate has a sliding through hole. The inner wall of the sliding through hole is slidably connected to a sliding plate. Before use, the base is installed inside the molding equipment, and the sliding frame is fixedly connected to the upper end of the molding device. Then, the molten metal is poured into the top of the gear base plate. The molding device drives the upper mold to squeeze the molten metal downward through the sliding frame, so that the molten metal cools and solidifies.

[0008] Preferably, the discharge assembly further includes a flow groove formed on the inner wall of the sliding plate, a toothed plate fixedly connected to the outer wall of the sliding plate, a gear frame fixedly connected to the top of the mounting plate, and a mounting block fixedly connected to the inner wall of the mounting through hole.

[0009] Preferably, the discharge assembly further includes a blocking rotating plate rotatably connected to the inner wall of the mounting block, a spring is fixedly connected to the top of the blocking rotating plate, the end of the spring away from the blocking rotating plate is fixedly connected to the inner wall of the mounting through hole, and a blocking component is slidably connected to the inner wall of the flow channel.

[0010] Preferably, the discharge assembly further includes a second toothed plate rotatably connected to the bottom of the blocking rotating plate. A limit rod is fixedly connected to the top of the mounting plate, and the outer wall of the limit rod is slidably connected to the outer wall of the second toothed plate. A pressure box is fixedly connected to the bottom of the gear base plate, and a spring telescopic tube is connected through the bottom of the pressure box. An electric telescopic rod is fixedly connected to the top of the base, and the end of the electric telescopic rod away from the base is fixedly connected to the bottom of the spring telescopic tube. When the equipment needs to demold, the power supply to the electric telescopic rod is turned on, causing the electric telescopic rod to drive the lower mold and piston ring to slide downward along the inner wall of the pressure cylinder through the gear base plate. At this time, the inner wall of the pressure cylinder will change from normal air pressure to high air pressure. The thrust generated by the high air pressure will act on the inner wall of the flow channel, forcing the sliding plate to slide upward along the inner wall of the sliding through hole. During this process, the sliding plate drives the first toothed plate to move upward synchronously. The upward-moving first toothed plate forces the second toothed plate to slide downward along the outer wall of the limit rod through the gear frame. The downward movement of the second toothed plate will drive the blocking rotating plate to rotate downward around the mounting block, presenting as follows. Figure 6 In this state, a gap is formed between the blocking rotating plate and the mounting through hole.

[0011] Preferably, the blocking component includes a sliding block slidably connected to the inner wall of the flow channel. The bottom of the sliding block has a groove. A control component is connected through the side wall of the pressure box. As the sliding plate moves upward, the flow channel will exceed the highest position of the sliding through hole, allowing the high-pressure gas inside the pressure cylinder to enter the installation through hole through the gap between the flow channel and the sliding through hole. The gas inside the installation through hole acts on the side wall of the finished product through the gap between the blocking rotating plate and the installation through hole. Through the application of the above components, the adhesion between the product and the lower mold is separated by high-pressure gas, avoiding the slight deformation of the product caused by the traditional push rod. Taking advantage of the characteristic of the flow channel and the upward movement of the sliding plate, a blocking component is set inside the equipment. When the high-pressure gas inside the pressure cylinder acts on the outer wall of the product, the high-pressure gas acts on the outer wall of the finished product, but does not remove the adhesive part in the area. At this time, the adhesive area and the pressure cylinder are in a sealed state. The high-pressure gas is transmitted upward through the gap between the flow channel, the sliding block, and the sliding through hole. At this time, the gas only has pressure and no flow velocity.

[0012] Preferably, the control component includes several pneumatic telescopic tubes fixedly connected to the side wall of the pressure box. A limit block is fixedly connected to the bottom of the gear base plate, and a sliding bracket is slidably connected to the inner wall of the limit block. The high-pressure gas completely breaks through the adhesion area, and the gas in the adhesion position can be discharged outward through the breakthrough position, so that the high-pressure gas inside the pressure cylinder is connected to the external environment. At this time, the high-pressure gas inside the pressure cylinder changes to low pressure. When the gas passes through the gap between the flow groove, the sliding block, and the sliding through hole, since the pressure cylinder is connected to the external environment, the pressure is converted into gas velocity. The air velocity will act on the groove, forcing the groove to slide upward along the inner wall of the flow groove. The upward-moving groove will completely seal the gap between the flow groove and the mounting through hole, presenting as... Figure 7 In the state of F, after the adhesion is completely removed from one of the mounting holes, the air outlet is immediately blocked by the sliding block to prevent the pressure of the high-pressure gas inside other air cylinders from decreasing due to depressurization of a single mounting hole, thus affecting the removal effect at other locations.

[0013] Preferably, the control component further includes an arc-shaped groove formed at the end of the sliding bracket away from the pressure box. The end of the sliding bracket away from the arc-shaped groove is fixedly connected to the side wall of the pneumatic telescopic tube. Utilizing the characteristic of the aforementioned electric telescopic rod driving the gear base plate downwards, a control component is installed inside the equipment. When the electric telescopic rod retracts, as it drives the gear base plate downwards, the downward movement of the electric telescopic rod will cause the spring telescopic tube to extend. This causes the spring telescopic tube to draw gas from the inside of multiple pneumatic telescopic tubes through the pressure box, causing the pneumatic telescopic tubes to contract. The contracted pneumatic telescopic tubes drive the sliding bracket to move along the inner wall of the limiting block towards the pressure box, while the sliding bracket moves the arc-shaped groove away from the sliding block. The top of the arc-shaped groove no longer restricts the sliding block and sliding plate. When the equipment starts casting, the arc-shaped groove is located on the inner wall of the flow channel, restricting the upward movement of the sliding plate and sliding block. When the lower mold is squeezed by the upper mold, the pressure will be transmitted to the blocking rotating plate through the molten metal, causing the blocking rotating plate to rotate downward. The blocking rotating plate forces the toothed plate and the sliding plate to rotate upward through the toothed plate and the gear frame. However, during this process, the arc-shaped groove restricts the upward movement of the sliding plate through the sliding block. Through the application of the above components, it is ensured that the gear base plate and multiple blocking rotating plates are in a parallel state when the equipment is under pressure casting, ensuring that the bottom of the finished product is flat and improving the flatness of the bottom of the product.

[0014] Preferably, the control component further includes a hydraulic telescopic rod 1 fixedly connected to the outer wall of the sliding bracket. The other end of the hydraulic telescopic rod 1 is fixedly connected to the outer wall of the limiting block. A transmission pipe is connected through the side wall of the hydraulic telescopic rod 1. Utilizing the characteristic of the sliding bracket sliding along the inner wall of the limiting block, a limiting ring is set inside the equipment. When the sliding bracket is pulled towards the pressure box by the pneumatic telescopic pipe, the hydraulic telescopic rod 1 will extend. The extended hydraulic telescopic rod 1 draws liquid from the corresponding hydraulic telescopic rod 2 through the transmission pipe, causing several hydraulic telescopic rods 2 to drive the limiting ring upward. During the upward movement of the limiting ring, the limiting ring will restrict the contraction speed and height of multiple hydraulic telescopic rods 2, indirectly controlling the extension efficiency of multiple hydraulic telescopic rods 1, and simultaneously controlling the sliding efficiency of multiple sliding brackets. Through the application of the above components, the sliding speed of multiple sliding brackets is ensured to be equal, avoiding the situation where one of the arc grooves contracts slowly, affecting the sliding speed of the subsequent sliding plate.

[0015] Preferably, a number of hydraulic telescopic rods 2 are fixedly connected to the bottom of the pressure box, and a limiting ring is fixedly connected to the end of each hydraulic telescopic rod 2 away from the pressure box. The end of the transmission pipe away from the hydraulic telescopic rod 1 is connected through to the side wall of the hydraulic telescopic rod 2.

[0016] The present invention has the following beneficial effects:

[0017] (1) This invention addresses the problem of excessive contact area between the finished product and the inner wall of the lower mold. It incorporates a pneumatic mechanism and a discharge assembly inside the equipment. Before use, the base is installed inside the molding equipment, ensuring a fixed connection between the sliding frame and the upper end of the molding device. Then, the molten metal is poured into the top of the gear base plate. The molding device, through the sliding frame, drives the upper mold to press the molten metal downwards, allowing the molten metal to cool and solidify. When demolding is required, the power to the electric telescopic rod is switched on, causing the electric telescopic rod to drive the lower mold and piston ring to slide downwards along the inner wall of the pneumatic cylinder through the gear base plate. At this time, the inner wall of the pneumatic cylinder changes from normal pressure to high pressure. The thrust generated by the high pressure acts on the inner wall of the flow channel, forcing the sliding plate to slide upwards along the inner wall of the sliding through-hole. During this process, the sliding plate drives the toothed plate to move upwards synchronously. The upward-moving toothed plate, through the gear frame, forces the toothed plate to slide downwards along the outer wall of the limiting rod. The downward movement of the toothed plate will cause the blocking rotating plate to rotate downwards around the mounting block, presenting as follows: Figure 6 In this state, a gap is formed between the blocking rotating plate and the mounting through hole; as the sliding plate moves upward, the flow groove will exceed the highest position of the sliding through hole, allowing the high-pressure gas inside the air cylinder to enter the mounting through hole through the gap between the flow groove and the sliding through hole. The gas inside the mounting through hole acts on the side wall of the finished product through the gap between the blocking rotating plate and the mounting through hole. Through the application of the above components, high-pressure gas is used to separate the product from the lower mold, avoiding the slight deformation of the product caused by the traditional push rod.

[0018] (2) This invention utilizes the characteristic of the electric telescopic rod driving the gear base plate downward. A control component is installed inside the equipment. When the electric telescopic rod retracts, it drives the gear base plate downward. This downward movement of the electric telescopic rod causes the spring telescopic tube to extend, allowing it to draw gas from multiple pneumatic telescopic tubes through the pressure box. This causes the pneumatic telescopic tubes to contract. The contracted pneumatic telescopic tubes drive the sliding bracket to move along the inner wall of the limiting block towards the pressure box. The sliding bracket then moves the arc-shaped groove away from the top of the sliding block, so that the arc-shaped groove no longer restricts the sliding block and the sliding plate. Meanwhile, in the design... When casting begins, the arc-shaped groove is located on the inner wall of the flow channel, restricting the upward movement of the sliding plate and sliding block. When the lower mold is squeezed by the upper mold, the pressure is transmitted to the blocking rotating plate through the molten metal, causing the blocking rotating plate to rotate downward. The blocking rotating plate, through the second gear plate and the gear frame, forces the first gear plate and the sliding plate to rotate upward. However, during this process, the arc-shaped groove restricts the upward movement of the sliding plate through the sliding block. Through the application of the above components, it is ensured that the gear base plate and multiple blocking rotating plates are in a parallel state when the equipment is under pressure casting, ensuring the flatness of the bottom of the finished product and improving the flatness effect of the bottom of the product.

[0019] (3) This invention utilizes the characteristic of the sliding bracket sliding along the inner wall of the limiting block. A limiting ring is set inside the equipment. When the sliding bracket is pulled towards the pressure box by the pneumatic telescopic tube, the first hydraulic telescopic rod will extend. The extended first hydraulic telescopic rod draws liquid from the corresponding second hydraulic telescopic rod through the transmission pipe, causing several second hydraulic telescopic rods to drive the limiting ring to move upward. During the upward movement of the limiting ring, the limiting ring will restrict the speed and height of the contraction of multiple second hydraulic telescopic rods, indirectly controlling the extension efficiency of multiple first hydraulic telescopic rods and controlling the sliding efficiency of multiple sliding brackets. Through the application of the above components, the sliding speed of multiple sliding brackets is ensured to be equal, avoiding the slow contraction speed of one arc groove, which would affect the sliding speed of the subsequent sliding plate.

[0020] (4) This invention utilizes the characteristic of the sliding plate of the flow channel moving upwards. A blocking component is installed inside the equipment. When the high-pressure gas inside the pneumatic cylinder acts on the outer wall of the product, two states will occur: First, the high-pressure gas acts on the outer wall of the finished product, but does not remove the adhesive parts in the area. At this time, the adhesive area and the pneumatic cylinder are in a sealed state. The high-pressure gas is transmitted upwards through the gap between the flow channel, the sliding block, and the sliding through hole. At this time, the gas only has pressure and no flow velocity. Second, the high-pressure gas completely breaks through the adhesive area. The gas in the adhesive position can be discharged outwards through the breakthrough position, so that the high-pressure gas inside the pneumatic cylinder is connected to the external environment. At this time, the high-pressure gas inside the pneumatic cylinder changes to low pressure. When the gas passes through the gap between the flow channel, the sliding block, and the sliding through hole, since the pneumatic cylinder is connected to the external environment, the pressure is converted into gas velocity. The air velocity will act on the groove, forcing the groove to slide upwards along the inner wall of the flow channel. The upward-moving groove will completely block the gap between the flow channel and the installation through hole, presenting as follows. Figure 7 In the state of F, after the adhesion is completely removed from one of the mounting holes, the air outlet is immediately blocked by the sliding block to prevent the pressure of the high-pressure gas inside other air cylinders from decreasing due to depressurization of a single mounting hole, thus affecting the removal effect at other locations.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1, please refer to Figure 1 - Figure 6 The present invention is a precision forging mold for mechanical transmission gears, including a base 1, a slide rail 11 fixedly connected to the top of the base 1, a sliding frame 12 slidably connected to the inner wall of the slide rail 11, and an upper mold 13 fixedly connected to the bottom of the sliding frame 12.

[0037] The pneumatic mechanism 2 includes a lower mold 23, a pneumatic cylinder 21 and a piston ring 22 for fixing and supporting the lower mold 23, and a discharge assembly 3 for discharging the finished product inside the lower mold 23.

[0038] The top of the base 1 is fixedly connected to the bottom of the air cylinder 21, the inner wall of the air cylinder 21 is slidably connected to the outer wall of the piston ring 22, and the inner wall of the piston ring 22 is fixedly connected to the outer wall of the lower mold 23.

[0039] The material discharge assembly 3 includes a gear base plate 31 fixedly connected to the inner wall of the lower mold 23. The side wall of the gear base plate 31 is provided with several mounting through holes 32. The inner wall of the several mounting through holes 32 is fixedly connected with a mounting plate 33. The inner wall of the mounting plate 33 is provided with a sliding through hole 34. The inner wall of the sliding through hole 34 is slidably connected with a sliding plate 35. Before use, the base 1 is installed inside the molding equipment, and the sliding frame 12 is fixedly connected to the upper end of the molding device. Then, the molten metal is poured into the top of the gear base plate 31. The molding device drives the upper mold 13 to squeeze the molten metal downward through the sliding frame 12, so that the molten metal cools and forms.

[0040] The discharge assembly 3 also includes a flow groove 36 opened on the inner wall of the sliding plate 35, a toothed plate 37 fixedly connected to the outer wall of the sliding plate 35, a gear frame 38 fixedly connected to the top of the mounting plate 33, and a mounting block 39 fixedly connected to the inner wall of the mounting through hole 32.

[0041] The discharge assembly 3 also includes a blocking rotating plate 310 rotatably connected to the inner wall of the mounting block 39. A spring 311 is fixedly connected to the top of the blocking rotating plate 310. The end of the spring 311 away from the blocking rotating plate 310 is fixedly connected to the inner wall of the mounting through hole 32. A blocking assembly 4 is slidably connected to the inner wall of the flow groove 36.

[0042] The discharge assembly 3 also includes a toothed plate 312 rotatably connected to the bottom of the blocking rotating plate 310. A limit rod 313 is fixedly connected to the top of the mounting plate 33. The outer wall of the limit rod 313 is slidably connected to the outer wall of the toothed plate 312. A pressure box 314 is fixedly connected to the bottom of the gear base plate 31. A spring telescopic tube 315 is connected through the bottom of the pressure box 314. An electric telescopic rod 316 is fixedly connected to the top of the base 1. The end of the electric telescopic rod 316 away from the base 1 is fixedly connected to the bottom of the spring telescopic tube 315. When the equipment needs to demold, the power supply to the electric telescopic rod 316 is turned on, so that the electric telescopic rod... 316 drives the lower mold 23 and piston ring 22 to slide downward along the inner wall of the pneumatic cylinder 21 via the gear base plate 31. At this time, the inner wall of the pneumatic cylinder 21 will change from normal air pressure to high air pressure. The thrust generated by the high air pressure will act on the inner wall of the flow groove 36, forcing the sliding plate 35 to slide upward along the inner wall of the sliding through hole 34. During this process, the sliding plate 35 drives the toothed plate 37 to move upward synchronously. The upward moving toothed plate 37 forces the toothed plate 312 to slide downward along the outer wall of the limit rod 313 via the gear frame 38. The downward movement of the toothed plate 312 will drive the blocking rotating plate 310 to rotate downward around the mounting block 39, presenting as follows. Figure 6In this state, a gap is formed between the blocking rotating plate 310 and the mounting through hole 32.

[0043] Example 2, please refer to Figure 7 - Figure 11 This invention relates to a precision forging die for mechanical transmission gears. Based on Embodiment 1, the blocking component 4 includes a sliding block 41 slidably connected to the inner wall of the flow channel 36. A groove 42 is provided at the bottom of the sliding block 41. A control component 5 is connected through the side wall of the pressure box 314. As the sliding plate 35 moves upward, the flow channel 36 will exceed the highest position of the sliding through hole 34, allowing high-pressure gas inside the pressure cylinder 21 to enter the mounting through hole 32 through the gap between the flow channel 36 and the sliding through hole 34. Meanwhile, the gas inside the mounting through hole 32 acts through the gap between the blocking rotating plate 310 and the mounting through hole 32. On the side wall of the finished product, through the application of the above components, high-pressure gas is used to separate the product from the lower mold 23, avoiding the slight deformation of the product caused by the traditional push rod. Taking advantage of the upward movement of the sliding plate 35 indicated by the flow channel 36, a blocking component 4 is set inside the equipment. When the high-pressure gas inside the air cylinder 21 acts on the outer wall of the product, the high-pressure gas acts on the outer wall of the finished product, but does not remove the adhesive part in the area. At this time, the adhesive area and the air cylinder 21 are in a sealed state. The high-pressure gas is transmitted upward through the gap between the flow channel 36, the sliding block 41, and the sliding through hole 34. At this time, the gas only has pressure and no flow velocity.

[0044] The control component 5 includes several pneumatic telescopic tubes 51 fixedly connected to the side wall of the pressure box 314. A limit block 52 is fixedly connected to the bottom of the gear base plate 31. A sliding bracket 53 is slidably connected to the inner wall of the limit block 52. The high-pressure gas completely breaks through the adhesion area, and the gas in the adhesion position can be discharged outward through the breakthrough position, so that the high-pressure gas inside the pressure cylinder 21 is connected to the external environment. At this time, the high-pressure gas inside the pressure cylinder 21 changes to low pressure. When the gas passes through the gap between the flow groove 36, the sliding block 41, and the sliding through hole 34, since the pressure cylinder 21 is connected to the external environment, the pressure is converted into gas flow velocity. The air flow velocity will act on the groove 42, forcing the groove 42 to slide upward along the inner wall of the flow groove 36. The upward-moving groove 42 will completely block the gap between the flow groove 36 and the mounting through hole 32, presenting as... Figure 7 In the state of F, after the adhesion is completely removed from one of the mounting through holes 32, the air outlet is immediately blocked by the sliding block 41 to prevent the pressure of the high-pressure gas inside other air cylinders 21 from decreasing due to the depressurization of a single mounting through hole 32, thus affecting the removal effect at other positions.

[0045] The control component 5 also includes an arcuate groove 54 formed at the end of the sliding bracket 53 away from the pressure box 314. The end of the sliding bracket 53 away from the arcuate groove 54 is fixedly connected to the side wall of the pneumatic telescopic tube 51. Utilizing the characteristic that the electric telescopic rod 316 drives the gear base plate 31 to move downward, the control component 5 is installed inside the equipment. When the electric telescopic rod 316 retracts, as it drives the gear base plate 31 to move downward, the downward movement of the electric telescopic rod 316 will cause the spring telescopic tube 315 to extend. This causes the spring telescopic tube 315 to draw gas from the multiple pneumatic telescopic tubes 51 through the pressure box 314, causing the pneumatic telescopic tubes 51 to contract. The contracted pneumatic telescopic tubes 51 drive the sliding bracket 53 to move along the inner wall of the limiting block 52 towards the pressure box 314, while the sliding bracket 53 drives the arcuate groove 54 away from the pressure box 314. The top of the moving block 41 allows the arc groove 54 to no longer restrict the sliding block 41 and the sliding plate 35. When the equipment starts casting, the arc groove 54 is located on the inner wall of the flow channel 36, restricting the upward movement of the sliding plate 35 and the sliding block 41. When the lower mold 23 is squeezed by the upper mold 13, the pressure will be transmitted to the blocking rotating plate 310 through the melt, causing the blocking rotating plate 310 to rotate downward. The blocking rotating plate 310 forces the toothed plate 37 and the sliding plate 35 to rotate upward through the toothed plate 2 312 and the gear frame 38. However, during this process, the arc groove 54 restricts the upward movement of the sliding plate 35 through the sliding block 41. Through the application of the above components, it is ensured that the gear base plate 31 and the multiple blocking rotating plates 310 are in a parallel state when the equipment is under pressure casting, ensuring that the bottom of the finished product is flat and improving the flatness of the bottom of the product.

[0046] Control component 5 also includes a hydraulic telescopic rod 55 fixedly connected to the outer wall of the sliding bracket 53. The other end of the hydraulic telescopic rod 55 is fixedly connected to the outer wall of the limiting block 52. A transmission pipe 56 is connected through the side wall of the hydraulic telescopic rod 55. Taking advantage of the characteristic that the sliding bracket 53 slides along the inner wall of the limiting block 52, a limiting ring 58 is set inside the equipment. When the sliding bracket 53 is pulled towards the pressure box 314 by the pneumatic telescopic pipe 51, the hydraulic telescopic rod 55 will extend. The extended hydraulic telescopic rod 55 is then drawn out through the transmission pipe 56. The fluid inside the hydraulic telescopic rod 57 causes several hydraulic telescopic rods 57 to move the limiting ring 58 upward. During the upward movement of the limiting ring 58, the limiting ring 58 restricts the speed and height of the retraction of multiple hydraulic telescopic rods 57, indirectly controlling the extension efficiency of multiple hydraulic telescopic rods 55, and simultaneously controlling the sliding efficiency of multiple sliding brackets 53. Through the application of the above components, the sliding speed of multiple sliding brackets 53 is ensured to be equal, avoiding the situation where the retraction speed of one of the arc grooves 54 is too slow, which would affect the sliding speed of the subsequent sliding plate 35.

[0047] Several hydraulic telescopic rods 57 are fixedly connected to the bottom of the pressure box 314. A limiting ring 58 is fixedly connected to the end of the hydraulic telescopic rods 57 away from the pressure box 314. The end of the transmission pipe 56 away from the hydraulic telescopic rod 55 is connected to the side wall of the hydraulic telescopic rod 57.

[0048] A specific application of this embodiment is as follows: Before use, the base 1 is installed inside the molding equipment, and the sliding frame 12 is fixedly connected to the upper end of the molding device. Then, the molten metal is poured into the top of the gear base plate 31. The molding device drives the upper mold 13 downward to squeeze the molten metal through the sliding frame 12, so that the molten metal cools and solidifies. When the equipment needs to be demolded, the power supply of the electric telescopic rod 316 is turned on, so that the electric telescopic rod 316 drives the lower mold 23 and the piston ring 22 along the air cylinder 21 through the gear base plate 31. As the inner wall slides downwards, the inner wall of the pneumatic cylinder 21 changes from normal air pressure to high air pressure. The thrust generated by the high air pressure acts on the inner wall of the flow groove 36, forcing the sliding plate 35 to slide upwards along the inner wall of the sliding through hole 34. During this process, the sliding plate 35 drives the toothed plate 37 to move upwards synchronously. The upward-moving toothed plate 37 forces the toothed plate 312 to slide downwards along the outer wall of the limiting rod 313 through the gear frame 38. The downward movement of the toothed plate 312 will drive the blocking rotating plate 310 to rotate downwards around the mounting block 39, presenting a shape as shown in the image. Figure 6 In this state, a gap is formed between the blocking rotating plate 310 and the mounting through hole 32; as the sliding plate 35 moves upward, the flow groove 36 will exceed the highest position of the sliding through hole 34, so that the high-pressure gas inside the air cylinder 21 enters the mounting through hole 32 through the gap between the flow groove 36 and the sliding through hole 34. The gas inside the mounting through hole 32 acts on the side wall of the finished product through the gap between the blocking rotating plate 310 and the mounting through hole 32. Through the application of the above components, the adhesion between the product and the lower mold 23 is separated by high-pressure gas, avoiding the slight deformation of the product caused by the traditional push rod.

[0049] Utilizing the characteristic of the electric telescopic rod 316 driving the gear base plate 31 to move downwards, a control component 5 is installed inside the equipment. When the electric telescopic rod 316 retracts, it drives the gear base plate 31 to move downwards. This downward movement of the electric telescopic rod 316 causes the spring telescopic tube 315 to extend, allowing it to draw gas from multiple pneumatic telescopic tubes 51 through the pressure box 314. This causes the pneumatic telescopic tubes 51 to contract. The contracted pneumatic telescopic tubes 51 drive the sliding bracket 53 to move along the inner wall of the limiting block 52 towards the pressure box 314. The sliding bracket 53, in turn, moves the arc groove 54 away from the top of the sliding block 41, so that the arc groove 54 no longer restricts the sliding block 41 and the sliding plate 35. When the equipment starts casting, the arc groove 54 is located on the inner wall of the flow groove 36, restricting the upward movement of the sliding plate 35 and the sliding block 41. When the top lower mold 23 is squeezed by the upper mold 13, the pressure will be transmitted to the blocking rotating plate 310 through the molten liquid, causing the blocking rotating plate 310 to rotate downward. The blocking rotating plate 310 forces the toothed plate 37 and the sliding plate 35 to move upward through the toothed plate 312 and the gear frame 38. However, during this process, the arc groove 54 restricts the upward movement of the sliding plate 35 through the sliding block 41. Through the application of the above components, it is ensured that the gear base plate 31 and the multiple blocking rotating plates 310 are in a parallel state when the equipment is under pressure casting, ensuring that the bottom of the finished product is flat and improving the flatness of the bottom of the product.

[0050] Taking advantage of the sliding support 53 sliding along the inner wall of the limiting block 52, a limiting ring 58 is provided inside the equipment. When the sliding support 53 is pulled towards the pressure box 314 by the pneumatic telescopic tube 51, the hydraulic telescopic rod 1 55 will extend. The extended hydraulic telescopic rod 1 55 draws liquid from the corresponding hydraulic telescopic rod 2 57 through the transmission tube 56, causing several hydraulic telescopic rods 2 57 to drive the limiting ring 58 to move upward. During the upward movement of the limiting ring 58, the limiting ring 58 will restrict the speed and height of the retraction of multiple hydraulic telescopic rods 2 57, indirectly controlling the extension efficiency of multiple hydraulic telescopic rods 1 55, and at the same time controlling the sliding efficiency of multiple sliding supports 53. Through the application of the above components, the sliding speed of multiple sliding supports 53 is ensured to be equal, avoiding the slow retraction speed of one of the arc grooves 54, which would affect the sliding speed of the subsequent sliding plate 35.

[0051] Taking advantage of the upward movement of the sliding plate 35 indicated by the aforementioned flow channel 36, a blocking component 4 is installed inside the equipment. When the high-pressure gas inside the pressure cylinder 21 acts on the outer wall of the product, two states will occur: First, the high-pressure gas acts on the outer wall of the finished product, but does not remove the adhesive parts in the area. At this time, the adhesive area and the pressure cylinder 21 are in a sealed state, and the high-pressure gas is transmitted upward through the gap between the flow channel 36, the sliding block 41, and the sliding through hole 34. At this time, the gas only has pressure and no flow velocity; Second, the high-pressure gas completely breaks through the adhesive area and is in a state of adhesion. The gas in the connected position can be discharged outward through the breakthrough position, allowing the high-pressure gas inside the pneumatic cylinder 21 to communicate with the external environment. At this time, the high-pressure gas inside the pneumatic cylinder 21 changes to low pressure. When the gas passes through the gap between the flow groove 36, the sliding block 41, and the sliding through hole 34, since the pneumatic cylinder 21 is connected to the external environment, the pressure is converted into gas velocity. The air velocity will act on the groove 42, forcing the groove 42 to slide upward along the inner wall of the flow groove 36. The upward-moving groove 42 will completely seal the gap between the flow groove 36 and the mounting through hole 32, presenting as... Figure 7 In the state of F, after the adhesion is completely removed from one of the mounting through holes 32, the air outlet is immediately blocked by the sliding block 41 to prevent the pressure of the high-pressure gas inside other air cylinders 21 from decreasing due to the depressurization of a single mounting through hole 32, thus affecting the removal effect at other positions.
