Description

Technical Field

[0001] This invention relates to the field of stainless steel investment casting technology, and more specifically, to a heat treatment device for stainless steel investment casting and its usage method. Background Technology

[0002] Investment casting is a relatively new method of casting metals. It is also known as whole-mold casting, evaporation casting, and cavityless casting. The prototype is made of foam plastic. When the molten metal is poured into the mold, the negative mold left by the casting sand is filled with the molten metal.

[0003] There are many existing technologies for heat treatment equipment used in stainless steel investment casting, such as:

[0004] Chinese Patent Publication No. CN216151010U discloses a device for casting high-boron wear-resistant stainless steel, including a U-shaped frame. A casting component and a feeding component are arranged within the U-shaped frame, with the casting component located below the feeding component. The casting component includes several first sliding rods fixed within the U-shaped frame, and several sets of casting molds are mounted on the first sliding rods. The feeding component includes a mounting frame and a first motor. Two second sliding rods are symmetrically fixed within the U-shaped frame. A lead screw is rotatably connected within the U-shaped frame. The two second sliding rods and the lead screw respectively pass through the mounting frame. A round rod is rotatably connected within the mounting frame. One end of the round rod passes through the mounting frame and is fixed with a handwheel. A placement cylinder is fixed to the circumference of the round rod, and a pressure ring is provided at the top of the placement cylinder. A crucible is placed inside the placement cylinder. A control panel is located on one side of the mounting frame. This invention, through the arrangement of the casting component and the feeding component, enables the addition of molten metal to the casting mold with mechanical assistance, reducing the labor intensity of the user.

[0005] However, in actual use, there are still some problems that urgently need to be solved:

[0006] 1. When casting the mold shell, it is usually necessary to move the container filled with molten material to the top of the mold shell for casting. Due to the large weight of the container, the labor intensity of the workers is high. Moreover, when the flow rate of the molten metal is too fast during casting, it will rush into the mold cavity with a large impact force, causing the molten metal to be violently agitated and splashed in the mold cavity, thereby drawing air into the molten metal to form bubbles, which affects the quality of the casting.

[0007] Therefore, a heat treatment device for stainless steel investment casting and its usage method are proposed. Summary of the Invention

[0008] The purpose of this invention is to provide a heat treatment device for stainless steel investment casting and its usage method, so as to solve the problems mentioned in the background art.

[0009] To address the aforementioned technical problems, one objective of this invention is to provide a heat treatment device for stainless steel investment casting, comprising a movable frame, a hollow rotating base rotatably mounted on the surface of the movable frame, an anti-foaming component inside the rotating base, upright plates on both sides of the rotating base, and a position adjustment component on the inner wall of the upright plates. The position adjustment component automatically adjusts a mold shell placed on the surface of the rotating base to position the mold shell at the center of the rotating base. A pouring component is positioned above the rotating base, and the pouring component moves horizontally to pour the mold shell placed on the surface of the rotating base. A fixing component is positioned above the position adjustment component; when the pouring component moves above the mold shell for pouring, the fixing component limits and fixes the pouring component to maintain the stability of the mold shell.

[0010] As a further improvement to this technical solution, the casting assembly includes a rotating motor disposed on the side wall of the movable frame, a lead screw disposed at the output end of the rotating motor, a moving block disposed on the surface of the lead screw, the moving block moving horizontally when the lead screw rotates, and a casting tank rotating below the moving block.

[0011] As a further improvement to this technical solution, the top of the casting tank is provided with a toothed block, and a movable rack is provided between the toothed block and the movable block, so as to drive the movable rack to move horizontally and drive the toothed block to mesh and rotate.

[0012] As a further improvement to this technical solution, cylinders and elastic telescopic rods are provided on both sides of the bottom of the moving block. The piston rod at the end of the cylinder pushes the end of the moving rack to move it. The end of the elastic telescopic rod is connected to the other end of the moving rack. After the push on the moving rack disappears, the elastic telescopic rod drives the moving rack to move in the opposite direction.

[0013] As a further improvement to this technical solution, baffles are provided on both sides of the movable block to block the flying material generated during casting, and the bottom of the baffles is provided with toothed strips.

[0014] As a further improvement to this technical solution, the position adjustment component includes a column cylinder disposed on the inner wall of the upright plate, a slide rod slidably disposed on the inner wall of the column cylinder, a return spring disposed between the column cylinder and the slide rod, and a clamping block disposed at the end of the slide rod, the clamping block being arc-shaped and fitting against the surface of the shell.

[0015] As a further improvement to this technical solution, a sliding groove is provided at the top of the column, and a toothed block is provided at the top of the end of the sliding rod away from the clamping block, and the toothed block slides on the inner wall of the sliding groove.

[0016] As a further improvement to this technical solution, the defoaming component includes a servo motor disposed inside a rotating base. The output shaft of the servo motor is provided with a belt shaft, and rotating rods are provided on both sides of the belt shaft. A transmission belt is provided between the belt shaft and the rotating rods. A swing arm is rotatably provided on the surface of the rotating rod, and a torsion spring is provided between the swing arm and the rotating rod.

[0017] As a further improvement to this technical solution, the fixing component includes an extension block disposed on the top of the upright plate, a T-shaped plate slidably disposed at the end of the extension block, a toothed plate disposed at the end of the T-shaped plate, a compression spring disposed between the toothed plate and the extension block, an eccentric wheel disposed above the T-shaped plate, and a gear rod disposed at the end of the eccentric wheel. When the baffle moves above the gear rod, the toothed strip drives the gear rod to mesh and rotate.

[0018] The second objective of this invention is to provide a processing method for a heat treatment device for stainless steel investment casting, comprising the heat treatment device for stainless steel investment casting described in any one of the above-mentioned embodiments, and including the following steps:

[0019] S1. By pressing the clamping block provided on the inner wall of the column, the slide rod provided at the end of the clamping block slides on the inner wall of the column. During the movement of the slide rod, the return spring is pressed. When the diameter between the clamping blocks is greater than the diameter of the shell, the shell is placed between the clamping blocks and the pressing is stopped. At this time, the slide rod is driven by the force of the return spring to move the clamping blocks relative to each other, so that the clamping blocks push and limit the shell placed in the middle.

[0020] S2. Control the output end of the rotating motor to drive the lead screw to rotate. The lead screw drives the moving block on its surface to move horizontally. When the moving block moves to the top of the shell, it pushes the casting tank to rotate below the moving block. Control the piston rod at the end of the cylinder to push the end of the moving rack. The moving rack moves horizontally under the force. When the moving rack moves, it drives the toothed block to rotate. The casting tank rotates around the toothed block to perform the casting operation.

[0021] S3. When the casting tank moves above the mold shell, the baffle drives the toothed strip to move on the surface of the gear rod. The toothed strip drives the gear rod to mesh and rotate, so that the eccentric part of the eccentric wheel at the end presses against the T-shaped plate, and the toothed plate at the end of the T-shaped plate limits the tooth block, thereby fixing the clamping position of the clamping block.

[0022] S4. When the pouring is completed, the output shaft of the servo motor drives the belt shaft to rotate. The output shaft of the servo motor rotates 90 degrees back and forth, and drives the rotating rod to rotate through the transmission belt. The rotating rod has a swing arm on its surface that drives the torsion spring to rotate coaxially. When the swing arm rotates to the vertical direction, it knocks and vibrates the bottom of the rotating base, thereby causing the shell to vibrate and expel the air.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This heat treatment equipment for stainless steel investment casting controls the output of a rotating motor to drive a lead screw to rotate. The lead screw drives a moving block on its surface to move horizontally. When the moving block moves above the mold shell, it pushes the casting tank to rotate below the moving block. The piston rod at the end of the control cylinder pushes the end of the moving rack, causing the moving rack to move horizontally under force. As the moving rack moves, it drives the toothed block to rotate. Since the toothed block is fixed at the top of the casting tank, the casting tank rotates around the toothed block, allowing the molten material inside the casting tank to be poured into the casting tank for casting. No operator intervention is required during the casting process, thus improving operational safety.

[0025] 2. In this heat treatment equipment for stainless steel investment casting, when the pouring tank moves above the mold shell, the baffle moves the toothed strip on the surface of the gear rod. The toothed strip drives the gear rod to mesh and rotate, causing the eccentric part of the eccentric wheel at the end to press against the T-shaped plate. The toothed plate at the end of the T-shaped plate limits the tooth block, thereby fixing the clamping position of the clamping block. When the solution impacts the inner wall of the mold shell, the clamping block can block the impact force generated by the solution, thereby improving the stability of the mold shell, reducing the difficulty of post-processing, and increasing the casting speed.

[0026] 3. In this heat treatment equipment for stainless steel investment casting, the mold shell is placed between the clamping blocks. At this time, the slide bar is driven by the force of the return spring to move the clamping blocks relative to each other, so that the clamping blocks push and limit the mold shell placed in the middle, thereby making the opening of the mold shell and the pouring gate of the pouring tank coaxial, avoiding the displacement of the molten material during the pouring process, thereby improving the utilization rate of the molten material.

[0041] 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.

[0042] One of the objectives of this invention is to refer to Figures 1-8 As shown, a heat treatment device for stainless steel investment casting is provided, including a movable frame 100, a rotating base 200 rotatably mounted on the surface of the movable frame 100, the rotating base 200 being hollow, an anti-foaming component inside the rotating base 200, upright plates 201 on both sides of the surface of the rotating base 200, and a position adjustment component 400 on the inner wall of the upright plate 201. The position adjustment component 400 is used to automatically adjust the mold shell placed on the surface of the rotating base 200 so that the mold shell is in the center position of the rotating base 200. A pouring component 300 is provided above the rotating base 200. The pouring component 300 moves horizontally to pour the mold shell placed on the surface of the rotating base 200. A fixing component 500 is provided above the position adjustment component 400. When the pouring component 300 moves above the mold shell for pouring, the fixing component 500 limits and fixes the pouring component 300 to keep the mold shell stable.

[0043] When casting the mold shell, it is usually necessary to move the workpiece and the container filled with molten material to the top of the mold shell for casting. Due to the large weight of the container, the labor intensity for workers is high. Therefore, the casting assembly 300 includes a rotary motor 301 mounted on the side wall of the moving frame 100. The output end of the rotary motor 301 is equipped with a lead screw 302, and a moving block 303 is provided on the surface of the lead screw 302. When the lead screw 302 rotates, the moving block 303 moves horizontally. A casting tank 304 is rotatably mounted below the moving block 303 for casting the mold shell. At the same time, the output end of the rotating motor 301 drives the lead screw 302 to rotate. The lead screw 302 drives the moving block 303 on its surface to move horizontally. When the moving block 303 moves above the mold shell, it pushes the casting tank 304 to rotate below the moving block 303, so that the molten material inside the casting tank 304 is poured into the mold shell. This allows multiple mold shells placed on the surface of the rotating base 200 to be cast quickly, avoiding the need for operators to repeatedly move and cast the tank, thereby reducing the labor intensity of the operators.

[0044] The high temperature of the molten material during pouring poses a safety hazard as it can easily cause burns to workers due to splashing. Therefore, the top of the pouring tank 304 is equipped with a toothed block 305, and a movable rack 306 is positioned between the toothed block 305 and the movable block 303. Pushing the movable rack 306 horizontally moves the toothed block 305, causing it to mesh and rotate. Cylinders 307 and elastic telescopic rods 308 are located on both sides of the bottom of the movable block 303. The piston rod at the end of the cylinder 307 pushes the end of the movable rack 306, causing it to move. The end of the elastic telescopic rod 308 is connected to the other end of the movable rack 306, and the movable rack 306 elastically extends and retracts after the push is removed. Rod 308 drives the moving rack 306 to move in the opposite direction. When the injection nozzle of the casting tank 304 moves to the top of the mold shell, the piston rod at the end of the control cylinder 307 pushes the end of the moving rack 306. The moving rack 306 moves horizontally under force. When the moving rack 306 moves, it drives the toothed block 305 to rotate. Since the toothed block 305 is fixed on the top of the casting tank 304, the toothed block 305 drives the casting tank 304 to rotate around the toothed block 305, so that the molten material inside the casting tank 304 is poured into the casting tank 304 for casting. No operator intervention is required during the casting process, thereby improving the safety of the operation.

[0045] When the pouring is completed, the piston rod at the end of the control cylinder 307 is reset. At this time, the end of the moving rack 306 away from the cylinder 307 is moved by the traction force of the elastic telescopic rod 308, so that the pouring tank 304 is once again in a state perpendicular to the horizontal plane, which facilitates the secondary pouring operation.

[0046] During the pouring of molten material, in order to avoid splashing of molten material, baffles 309 are provided on both sides of the moving block 303. The baffles 309 block the flying material generated during pouring. The bottom of the baffles 309 is provided with toothed strips 310. By placing the baffles 309 on the moving block 303 twice, the baffles 309 block the pouring area, preventing molten material from splashing and causing burns to nearby workers, thus improving the safety of the operation.

[0047] During the casting of the mold shell, since the casting tank 304 moves horizontally in a straight line, in order to facilitate quick adjustment of the mold shell's position and ensure that the opening of the mold shell is aligned with the gating gate of the casting tank 304, thus avoiding waste caused by spillage of molten material during casting, the position adjustment component 400 includes a column 401 mounted on the inner wall of the vertical plate 201. A sliding rod 402 is slidably mounted on the inner wall of the column 401, and a return spring 403 is provided between the column 401 and the sliding rod 402. A clamping block 404 is provided at the end of the sliding rod 402, and the clamping block 404 is arc-shaped and fits against the surface of the mold shell. A groove is provided at the top of the column 401, and a toothed block 405 is provided at the top of the sliding rod 402 away from the clamping block 404. The toothed block 405 slides on the inner wall of the groove. When placing the mold shell, the position adjustment component 400 controls the movement of the mold shell. Rotate the base 200 to 90°, and squeeze the clamping block 404 on the inner wall of the squeezing cylinder 401. The slide rod 402 at the end of the clamping block 404 slides on the inner wall of the cylinder 401. During the movement of the slide rod 402, it squeezes the return spring 403. When the diameter between the clamping blocks 404 is larger than the diameter of the mold shell, the mold shell is placed between the clamping blocks 404 and the squeezing is stopped. At this time, the slide rod 402 is driven by the force of the return spring 403 to drive the clamping blocks 404 to move relative to each other, so that the clamping blocks 404 push and limit the mold shell placed in the middle, so that the mold shell is at the center position of the clamping blocks 404, so that the opening of the mold shell is on the same axis as the gate of the casting tank 304, avoiding the displacement of the molten material during the casting process, thereby improving the utilization rate of the molten material.

[0048] When the flow rate of molten metal is too fast during casting, it will rush into the mold cavity with a large impact force, causing violent agitation and splashing within the cavity. This will draw air into the molten metal, forming bubbles and affecting the quality of the casting. Therefore, the defoaming component includes a servo motor 202 located inside the rotating base 200. The output shaft of the servo motor 202 is equipped with a belt shaft 203. Rotating rods 204 are located on both sides of the belt shaft 203. A transmission belt is provided between the belt shaft 203 and the rotating rods 204. A swing arm 205 is rotatably mounted on the surface of the rotating rod 204. The swing arm 205 and the rotating rod... A torsion spring 206 is provided between 204. When the casting of the shell is completed, the output shaft of the servo motor 202 drives the belt shaft 203 to rotate. The output shaft of the servo motor 202 rotates 90 degrees and reciprocates. The transmission belt drives the rotating rod 204 to rotate. Since the surface of the rotating rod 204 is provided with a swing arm 205, the swing arm 205 and the torsion spring 206 rotate coaxially. When the toothed block 305 rotates to the vertical direction, it knocks and vibrates the bottom of the rotating base 200 multiple times, thereby causing vibration inside the shell to be generated and air to be discharged, thereby improving the casting quality of the shell.

[0049] In practical use, when placing the mold shell, the rotating base 200 is controlled to rotate to 90° and be parallel to the operator, squeezing the clamping block 404 on the inner wall of the squeezing cylinder 401. The sliding rod 402 at the end of the clamping block 404 slides on the inner wall of the cylinder 401. During the movement of the sliding rod 402, it squeezes the return spring 403. When the diameter between the clamping blocks 404 is larger than the diameter of the mold shell, the mold shell is placed between the clamping blocks 404 and the squeezing is stopped. At this time, the sliding rod 402 is driven by the force of the return spring 403 to drive the clamping blocks 404 to move relative to each other, so that the clamping blocks 404 push and limit the mold shell placed in the middle, so that the opening of the mold shell is on the same axis as the pouring tank 304, avoiding the displacement of the molten material during the pouring process, thereby improving the utilization rate of the molten material. When the mold shell is placed, the rotating base 200 is controlled to return to its original position.

[0050] The output of the control motor 301 drives the lead screw 302 to rotate. The lead screw 302 drives the moving block 303 on its surface to move horizontally. When the moving block 303 moves above the mold shell, it pushes the casting tank 304 to rotate below the moving block 303. The piston rod at the end of the control cylinder 307 pushes the end of the moving rack 306. The moving rack 306 moves horizontally under force. When the moving rack 306 moves, it drives the toothed block 305 to rotate. Since the toothed block 305 is fixed on the top of the casting tank 304, the casting tank 304 rotates with the toothed block 305 as the center, so that the molten material inside the casting tank 304 is poured into the casting tank 304 for casting. No operator intervention is required during the casting process, thereby improving the safety of the operation.

[0051] When the casting tank 304 moves above the mold shell, the baffle 309 drives the toothed strip 310 to move on the surface of the gear rod 505. The toothed strip 310 drives the gear rod 505 to mesh and rotate, so that the eccentric part of the eccentric wheel 506 at the end squeezes the T-plate 502, and the toothed plate 503 at the end of the T-plate 502 limits the tooth block 405, thereby fixing the clamping position of the clamping block 404. When the solution impacts the inner wall of the mold shell, the clamping block 404 can block the impact force generated by the solution, thereby improving the stability of the mold shell, reducing the difficulty of post-processing, and increasing the casting speed.

[0052] When the casting of the mold shell is completed, the output shaft of the servo motor 202 drives the belt shaft 203 to rotate. The output shaft of the servo motor 202 rotates 90 degrees back and forth, which drives the rotating rod 204 to rotate through the transmission belt. Since the surface of the rotating rod 204 is provided with a swing arm 205, the swing arm 205 and the torsion spring 206 rotate coaxially. When the toothed block 305 rotates to the vertical direction, it knocks and vibrates the bottom of the rotating base 200 multiple times, thereby causing vibration inside the mold shell to be generated and air to be discharged, thereby improving the casting quality of the mold shell.

[0053] When casting the mold shell, if a large amount of solution impacts the inner wall of the mold shell, it can easily cause the solution inside the mold shell to slosh, resulting in solution splashing onto the surface of the mold shell and forming "cold beans" of unfused metal particles or "burrs," increasing the difficulty of post-processing. Therefore, the fixing component 500 includes an extension block 501 located at the top of the upright plate 201. A T-shaped plate 502 is slidably provided at the end of the extension block 501. A toothed plate 503 is provided at the end of the T-shaped plate 502. A compression spring 504 is provided between the toothed plate 503 and the extension block 501. An eccentric wheel 506 is provided above the T-shaped plate 502. A gear rod 505 is provided at the end of the eccentric wheel 506. The baffle 309 moves onto the gear rod 505. When the casting tank 304 moves above the mold shell, the baffle 309 moves the toothed strip 310 onto the surface of the gear rod 505, causing the toothed strip 310 to mesh and rotate. This causes the eccentric part of the eccentric wheel 506 at the end to press against the T-plate 502, and the toothed plate 503 at the end of the T-plate 502 to limit the tooth block 405, thereby fixing the clamping position of the slide bar 402. When the solution impacts the inner wall of the mold shell, the clamping block 404 can block the impact force generated by the solution, thereby improving the stability of the mold shell, reducing the difficulty of post-processing, and increasing the casting speed.

[0054] The second objective of this invention is to provide a processing method for a heat treatment device for stainless steel investment casting, comprising the heat treatment device for stainless steel investment casting as described above, and including the following steps:

[0055] S1. By pressing the clamping block 404 provided on the inner wall of the column cylinder 401, the slide rod 402 provided at the end of the clamping block 404 slides on the inner wall of the column cylinder 401. During the movement of the slide rod 402, it presses the return spring 403. When the diameter between the clamping blocks 404 is greater than the diameter of the shell, the shell is placed between the clamping blocks 404 and the pressing is stopped. At this time, the slide rod 402 is driven by the force of the return spring 403 to drive the clamping blocks 404 to move relative to each other, so that the clamping blocks 404 push and limit the shell placed in the middle.

[0056] S2. The output end of the control rotation motor 301 drives the lead screw 302 to rotate. The lead screw 302 drives the moving block 303 on its surface to move horizontally. When the moving block 303 moves to the top of the mold shell, it pushes the casting tank 304 to rotate below the moving block 303. The piston rod at the end of the control cylinder 307 pushes the end of the moving rack 306. The moving rack 306 moves horizontally under force. When the moving rack 306 moves, it drives the toothed block 305 to rotate. The casting tank 304 rotates with the toothed block 305 as the center to perform the casting operation.

[0057] S3. When the casting tank 304 moves above the mold shell, the baffle 309 drives the toothed strip 310 to move on the surface of the gear rod 505. The toothed strip 310 drives the gear rod 505 to mesh and rotate, so that the eccentric part of the eccentric wheel 506 at the end presses against the T-shaped plate 502, so that the toothed plate 503 at the end of the T-shaped plate 502 limits the tooth block 405, thereby fixing the clamping position of the clamping block 404.

[0058] S4. When the pouring is completed, the output shaft of the servo motor 202 drives the belt shaft 203 to rotate. The output shaft of the servo motor 202 rotates 90 degrees and reciprocates. The transmission belt drives the rotating rod 204 to rotate. The surface of the rotating rod 204 is provided with a swing arm 205, which drives the torsion spring 206 to rotate coaxially. When the swing arm 205 rotates to the vertical direction, it knocks and vibrates the bottom of the rotating base 200, thereby causing vibration inside the shell and expelling air.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.

The position adjustment assembly includes a column cylinder mounted on the inner wall of the upright plate, a slide rod slidably mounted on the inner wall of the column cylinder, a return spring between the column cylinder and the slide rod, a clamping block at the end of the slide rod, the clamping block being arc-shaped and fitting against the surface of the shell, a groove being opened at the top of the column cylinder, and a toothed block at the top of the end of the slide rod away from the clamping block, the toothed block sliding on the inner wall of the groove; the fixing assembly includes an extension block mounted on the top of the upright plate, a T-shaped plate slidably mounted at the end of the extension block, a toothed plate at the end of the T-shaped plate, a compression spring between the toothed plate and the extension block, an eccentric wheel above the T-shaped plate, and a gear rod at the end of the eccentric wheel; when the baffle moves above the gear rod, the toothed strip drives the gear rod to mesh and rotate.

2. The heat treatment equipment for stainless steel investment casting according to claim 1, characterized in that: The top of the casting tank is equipped with a toothed block, and a movable rack is provided between the toothed block and the movable block. Pushing the movable rack to move horizontally causes the toothed block to mesh and rotate.

3. The heat treatment equipment for stainless steel investment casting according to claim 2, characterized in that: The bottom of the moving block is equipped with cylinders and elastic telescopic rods on both sides. The piston rod at the end of the cylinder pushes the end of the moving rack to move it. The end of the elastic telescopic rod is connected to the other end of the moving rack. After the push on the moving rack disappears, the elastic telescopic rod drives the moving rack to move in the opposite direction.

4. The heat treatment equipment for stainless steel investment casting according to claim 3, characterized in that: The defoaming component includes a servo motor located inside a rotating base. The output shaft of the servo motor is equipped with a belt shaft, and rotating rods are located on both sides of the belt shaft. A transmission belt is provided between the belt shaft and the rotating rods. A swing arm is rotatably mounted on the surface of the rotating rod, and a torsion spring is provided between the swing arm and the rotating rod.

5. A method of using a heat treatment device for stainless steel investment casting, implemented by the heat treatment device for stainless steel investment casting according to any one of claims 4, characterized in that: Includes the following steps: S1. By pressing the clamping block provided on the inner wall of the column, the slide rod provided at the end of the clamping block slides on the inner wall of the column. During the movement of the slide rod, the return spring is pressed. When the diameter between the clamping blocks is greater than the diameter of the shell, the shell is placed between the clamping blocks and the pressing is stopped. At this time, the slide rod is driven by the force of the return spring to move the clamping blocks relative to each other, so that the clamping blocks push and limit the shell placed in the middle. S2. Control the output end of the rotating motor to drive the lead screw to rotate. The lead screw drives the moving block on its surface to move horizontally. When the moving block moves to the top of the shell, it pushes the casting tank to rotate below the moving block. Control the piston rod at the end of the cylinder to push the end of the moving rack. The moving rack moves horizontally under force. When the moving rack moves, it drives the toothed block to rotate. The casting tank rotates with the toothed block as the center to perform the casting operation. S3. When the casting tank moves above the mold shell, the baffle drives the toothed strip to move on the surface of the gear rod. The toothed strip drives the gear rod to mesh and rotate, so that the eccentric part of the eccentric wheel at the end presses against the T-shaped plate, and the toothed plate at the end of the T-shaped plate limits the tooth block, thereby fixing the clamping position of the clamping block. S4. When the pouring is completed, the output shaft of the servo motor drives the belt shaft to rotate. The output shaft of the servo motor rotates 90 degrees back and forth, and drives the rotating rod to rotate through the transmission belt. The rotating rod has a swing arm on its surface that drives the torsion spring to rotate coaxially. When the swing arm rotates to the vertical direction, it knocks and vibrates the bottom of the rotating base, thereby causing the shell to vibrate and expel the air.
