Description

Technical Field

[0001] This invention belongs to the field of casting cleaning technology, specifically a casting cleaning device for stainless steel pipe fittings casting processing. Background Technology

[0002] In the field of stainless steel pipe casting processing, after the casting is formed, there will still be some adhesion between the casting and the cast pipe opening. Therefore, by using casting cleaning equipment for stainless steel pipe casting processing, this adhesion is cut off, thereby completing the casting production of stainless steel pipe fittings.

[0003] A patent with publication number CN110788307A discloses a casting cleaning device for stainless steel pipe fittings casting processing, including a box body. The box body has an internal partition, which is fixedly connected to the inner side wall of the box body. The partition divides the box body into a working chamber and a miscellaneous chamber. A fixing rod is fixedly installed on the inner top of the working chamber. There are three sets of fixing rods arranged in parallel on the inner top of the working chamber. An installation block is fixedly installed on the bottom of the fixing rod. A connecting block is fixedly installed on the front side wall of the installation block. The connecting block is located in the center of the front side wall of the installation block. A blower nozzle is fixedly installed on one side wall of the connecting block. The blower nozzle is arc-shaped and the blower nozzle is directly below the installation block. A fixing block is fixedly installed on the bottom of the installation block. An arc-shaped groove is opened on the bottom of the fixing block. A limit clamp and a cleaning clamp are fixedly installed in the two sets of arc-shaped grooves in sequence.

[0004] However, existing methods for cleaning stainless steel pipe fittings involve first pouring molten stainless steel into the mold, then waiting a considerable amount of time for the molten steel to cool and solidify. This process is inefficient and prolongs the overall production cycle. When the molten steel cools and separates from the mold to remove the stainless steel fitting, the interaction between the molten steel and the mold during the cooling process easily causes steel to stick to the mold casting area. This is then removed manually by cutting and scraping. However, this method is labor-intensive, and the precision of the cutting and scraping is difficult to guarantee, which can easily damage the surface of the stainless steel fitting, affecting its quality and appearance, and also leading to low production efficiency.

[0005] Therefore, the present invention provides a casting cleaning device for stainless steel pipe fitting casting processing. 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 the present invention to solve its technical problem is as follows: The present invention provides a casting cleaning device for stainless steel pipe fittings casting steel processing, including a machine body, a top plate fixedly connected to the top of the machine body, a first hydraulic cylinder fixedly connected to the upper surface of the top plate, an upper mold plate provided at the output end of the first hydraulic cylinder, a lower mold plate fixedly connected to the upper surface of the machine body, a cooling assembly provided on the upper surface of the machine body, the cooling assembly including a second hydraulic cylinder fixedly connected to the upper surface of the machine body, a sealing plate fixedly connected to the output end of the second hydraulic cylinder, a rack plate fixedly connected to one side of the sealing plate, a plurality of connecting holes opened on one side of the rack plate, a fixing groove opened at the bottom end of the lower mold plate, a compression spring fixedly connected to the inner wall of the fixing groove, a plurality of positioning holes opened on the top wall of the fixing groove, a fixing plate fixedly connected to one end of the compression spring, and a plurality of auxiliary holes opened inside the fixing plate; A water outlet is provided on one side of the sealing plate, and a fixing hole is provided on one side of the upper mold plate. The fixing hole is located at the same position as the water outlet.

[0008] Preferably, the output end of the first hydraulic cylinder is fixedly connected to a first guide rail, a slider is slidably connected inside the first guide rail, and an upper mold plate is fixedly connected to the lower surface of the slider.

[0009] Preferably, a connecting pipe is fixedly connected to one side of the sealing plate, a fixing plate is fixedly connected to one end of the connecting pipe, an injection hole is opened on one side of the sealing plate, and mold grooves are opened on both the upper mold plate and the lower mold plate, with the injection hole facing the mold groove.

[0010] Preferably, a second guide rail is fixedly connected to one side of the sealing plate, a slide plate is slidably connected inside the second guide rail, a positioning frame is fixedly connected to one side of the slide plate, a positioning groove is provided inside the positioning frame, and a plurality of rotating columns are provided inside the positioning groove. The rotating columns are used to apply the release agent to one side of the sealing plate and the lower mold plate of the sealing plate.

[0011] Preferably, the side wall of the positioning groove is provided with a plurality of rotating grooves, and the bottom wall of each rotating groove is provided with a sliding groove. A spring is fixedly connected to the inner wall of the sliding groove, and a positioning block is fixedly connected to one end of the spring. The upper surface of the positioning block is rotatably connected to the rotating column, and a micro motor is provided inside the positioning block.

[0012] Preferably, a cutter is fixed to one side of the positioning frame, and the cutter is used to separate the sealing plate from the stainless steel pipe after casting is completed.

[0013] Preferably, a gear is rotatably connected to one side of the positioning frame, a transmission belt is driven to one side of the gear, a rotating disk is driven to one end of the transmission belt, and one side of the rotating disk is sandpaper.

[0014] Preferably, during the stainless steel pipe casting process, the first hydraulic cylinder is activated to drive the first guide rail and the upper mold plate to move downwards, causing the upper mold plate to merge with the lower mold plate. Then, the second hydraulic cylinder is activated, causing its output end sealing plate to approach the opening of the upper and lower mold plates, thereby sealing the mold groove and casting the stainless steel pipe fitting. Molten steel is then poured into a fixed plate, and the molten stainless steel flows along the injection plate into the connecting pipe, and then flows from the injection hole into the mold groove for casting the stainless steel pipe fitting. The process continues until the sealing plate approaches... During the process, the rack plate on one side of the sealing plate presses against the fixing plate on one side of the mold plate. The fixing plate moves into the fixing groove to compress the spring. After the fixing plate is pressed into the fixing groove, the auxiliary hole at the top of the fixing plate aligns with the positioning hole on the top wall of the fixing groove, and one end of the auxiliary hole aligns with the connecting hole on one side of the rack plate. After casting is completed, the pressure pump inside the machine is started to inject water. The water flows along the positioning hole, auxiliary hole and connecting hole to the water outlet on the sealing plate, and then flows into the fixing hole of the upper mold plate through the water outlet, thereby cooling the upper mold plate and the lower mold plate.

[0015] Preferably, with the assistance of the cooling components, after the stainless steel pipe fitting is cast, the second hydraulic cylinder is activated to retract the sealing plate. After the sealing plate retracts, the second guide rail on one side of the sealing plate is activated. The positioning frame on one side of the second guide rail can then clean one end of the sealing plate and the stainless steel pipe fitting. First, the positioning frame moves towards the sealing plate driven by the second guide rail. As the positioning frame approaches the sealing plate, the cutter at the end of the positioning frame pushes along the side of the sealing plate, thereby separating the stainless steel pipe fitting from the sealing plate. In addition, the rotating roller set inside the positioning frame is squeezed by the sealing plate and slides into the rotating groove, so that the rotating roller always fits against the sealing plate. Then, the bottom positioning block is activated. The micro motor built into the positioning block is activated, driving the rotating roller to rotate, so that the rotating roller coats the entire sealing plate with a release agent during its movement.

[0016] Preferably, a gear is provided on one side of the positioning frame. As the positioning frame moves toward the sealing plate, the gear meshes with the rack plate. The gear rotates under the drive of the rack plate. The rotation of the gear drives the transmission belt to rotate. The rotating belt drives the rotating disk to rotate. The rotation of the rotating disk thus performs a sanding operation on one end of the stainless steel pipe fitting.

[0017] The beneficial effects of this invention are as follows: 1. The stainless steel pipe fitting casting cleaning equipment of the present invention uses a first hydraulic cylinder and a second hydraulic cylinder to sequentially drive the mold closing and sealing plate to achieve mold closure and sealing at the opening, effectively avoiding problems such as molten steel leakage and pipe fitting dimensional deviation during casting, and improving casting forming accuracy and product qualification rate. In addition, the built-in flow channel casting structure allows molten steel to flow into the mold groove through the fixed plate, connecting pipe and injection hole, making the casting process more uniform and smooth, reducing defects such as air holes and looseness inside the pipe fitting. When the sealing plate is pressed, the rack plate squeezes the fixed plate to compress the compression spring, which can automatically realize the alignment of the positioning hole, auxiliary hole and connecting hole. After casting, the pressure pump injects water into the mold through the preset channel to cool the upper mold plate and the lower mold plate, which greatly shortens the casting cooling and forming cycle and improves the production efficiency and product quality of stainless steel pipe fitting casting.

[0018] 2. The stainless steel pipe fitting casting cleaning equipment of the present invention, after the pipe fitting is cast by the cooling component, automatically demolds and cleans the mold in conjunction with the second hydraulic cylinder and the second guide rail. After the sealing plate retracts, the positioning frame moves along the second guide rail, and the end cutter can separate the formed stainless steel pipe fitting from the sealing plate, avoiding pipe deformation, scratches and mold damage caused by manual demolding, ensuring the appearance and dimensional accuracy of the casting. The rotating roller in the positioning frame is squeezed and retracts adaptively, always in close contact with the surface of the sealing plate. With the built-in motor driving the rotation, the release agent can be evenly applied during the movement, without the need for separate machine stoppage for manual brushing, simplifying the process and improving the continuity of operation, increasing production efficiency, and ensuring uniform application of the release agent, reducing the risk of subsequent mold sticking, extending the service life of the mold, and improving the automation level of pipe fitting casting.

[0021] 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.

[0022] Example 1: As Figures 1 to 7 As shown in the embodiment of the present invention, a casting cleaning device for stainless steel pipe fittings is provided. A top plate is fixedly connected to the upper part of the machine body. A first hydraulic cylinder is fixedly connected to the upper surface of the top plate. An upper mold plate is provided at the output end of the first hydraulic cylinder. A lower mold plate is fixedly connected to the upper surface of the machine body. A cooling assembly is provided on the upper surface of the machine body. The cooling assembly includes a second hydraulic cylinder fixedly connected to the upper surface of the machine body. A sealing plate is fixedly connected to the output end of the second hydraulic cylinder. A rack plate is fixedly connected to one side of the sealing plate. Several connecting holes are opened on one side of the rack plate. A fixing groove is opened at the bottom end of the lower mold plate. A compression spring is fixedly connected to the inner wall of the fixing groove. The top wall of the fixed groove has several positioning holes, and one end of the compression spring is fixedly connected to a fixed plate. The fixed plate has several auxiliary holes inside. One side of the sealing plate has a water outlet hole, and one side of the upper mold plate has a fixed hole. The fixed hole and the water outlet hole are in the same position. The output end of the first hydraulic cylinder is fixedly connected to the first guide rail. A slider is slidably connected inside the first guide rail. The lower surface of the slider is fixedly connected to the upper mold plate. One side of the sealing plate is fixedly connected to a connecting pipe. One end of the connecting pipe is fixedly connected to a fixed plate. One side of the sealing plate has an injection hole. Both the upper mold plate and the lower mold plate have mold grooves. The injection hole is directly opposite the mold groove.

[0023] Specifically, in the existing stainless steel pipe fitting casting cleaning equipment, after the stainless steel liquid is poured into the mold, a long time is required for the molten steel to cool and solidify. This process is inefficient and prolongs the overall production cycle. When the molten steel is cooled and separated from the mold to remove the stainless steel pipe fitting, due to the interaction between the molten steel and the mold during the cooling process, steel tends to stick to the mold casting area. Therefore, it is removed by manual cutting and scraping. However, this method consumes a lot of labor costs, and the accuracy of cutting and scraping is difficult to guarantee. It is easy to damage the surface of the stainless steel pipe fitting, affecting the quality and appearance of the pipe fitting, and also leading to low production efficiency. Therefore, this invention solves the above problems by setting the above structure. First, during the stainless steel pipe casting process, the first hydraulic cylinder is activated to drive the first guide rail and the upper mold plate to move downwards, so that the upper mold plate and the lower mold plate merge. Then, the second hydraulic cylinder is activated, so that the sealing plate at the output end of the second hydraulic cylinder moves close to the opening end of the upper mold plate and the lower mold plate, and then the mold groove is sealed to cast the stainless steel pipe. Then, by pouring molten steel into the fixed plate, the stainless steel liquid flows along the fixed plate into the interior of the connecting pipe, and then flows into the mold groove from the injection hole to cast the stainless steel pipe. During casting, as the sealing plate approaches, the rack plate on one side of the sealing plate presses against the fixing plate on one side of the mold plate. The fixing plate moves into the fixing groove to compress the spring. After the fixing plate is pressed into the fixing groove, the auxiliary hole at the top of the fixing plate aligns with the positioning hole on the top wall of the fixing groove, and one end of the auxiliary hole aligns with the connecting hole on one side of the rack plate. After casting is completed, the pressure pump inside the machine is started to inject water. The water flows along the positioning hole, auxiliary hole and connecting hole to the water outlet on the sealing plate, and then flows into the fixing hole of the upper mold plate through the water outlet, thereby cooling the upper mold plate and the lower mold plate. The mold closing and sealing plate are driven sequentially by the first and second hydraulic cylinders to achieve mold closure and sealing at the opening, effectively avoiding problems such as molten steel leakage and pipe fitting dimensional deviation during casting, thus improving casting accuracy and product qualification rate. In addition, the built-in flow channel casting structure allows molten steel to flow into the mold groove through the fixed plate, connecting pipe and injection hole, making the casting process more uniform and smooth, reducing defects such as air holes and looseness inside the pipe fitting. When the sealing plate is pressed, the fixed plate is squeezed by the rack plate to compress the compression spring, which can automatically align the positioning hole, auxiliary hole and connecting hole. After casting, the pressure pump injects water into the mold through the preset channel to cool the upper mold plate and the lower mold plate, which greatly shortens the casting cooling and forming cycle and improves the production efficiency and product quality of stainless steel pipe fitting casting.

[0024] Example 2: Figures 1 to 7As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a second guide rail is fixedly connected to one side of the sealing plate, a slide plate is slidably connected inside the second guide rail, a positioning frame is fixedly connected to one side of the slide plate, a positioning groove is opened inside the positioning frame, and several rotating columns are opened inside the positioning groove. The rotating columns are used to coat the release agent on one side of the sealing plate and the lower mold plate of the sealing plate; several rotating grooves are opened on the side wall of the positioning groove, and a sliding groove is opened on the bottom wall of each rotating groove. A spring is fixedly connected to the inner wall of the sliding groove, and a positioning block is fixedly connected to one end of the spring. The upper surface of the positioning block is rotatably connected to the rotating column, and a micro motor is installed inside the positioning block; a cutter is fixedly connected to one side of the positioning frame. The cutter is used to separate the sealing plate from the stainless steel pipe after casting.

[0025] Specifically, with the assistance of the cooling components, after the stainless steel pipe is cast, the second hydraulic cylinder is activated to retract the sealing plate. After the sealing plate retracts, the second guide rail on one side of the sealing plate is activated. The positioning frame on one side of the second guide rail can then clean one end of the sealing plate and the stainless steel pipe. First, the positioning frame moves towards the sealing plate driven by the second guide rail. As the positioning frame approaches the sealing plate, the cutter at the end of the positioning frame pushes along the side of the sealing plate, thereby separating the stainless steel pipe from the sealing plate. In addition, the rotating roller set inside the positioning frame is squeezed by the sealing plate and slides into the rotating groove, so that the rotating roller is always in contact with the sealing plate. Then, the bottom positioning block is activated. The micro motor built into the positioning block is activated, driving the rotating roller to rotate, so that the rotating roller coats the entire sealing plate with a release agent during its movement. After the pipe casting is completed by the cooling assembly, automatic demolding and mold cleaning are achieved in conjunction with the second hydraulic cylinder and the second guide rail. After the sealing plate retracts, the positioning frame moves along the second guide rail, and the end cutter can separate the formed stainless steel pipe from the sealing plate. This avoids pipe deformation, scratches and mold damage caused by manual demolding, ensuring the appearance and dimensional accuracy of the casting. The rotating roller in the positioning frame is squeezed and retracts adaptively, always in close contact with the surface of the sealing plate. With the built-in motor driving the rotation, the release agent can be evenly applied during the movement. There is no need to stop the machine to apply it manually, which simplifies the process and improves the continuity of operation, increases production efficiency, and makes the release agent evenly applied, reducing the risk of subsequent sticking, extending the service life of the mold, and improving the automation level of pipe casting.

[0026] like Figure 7 As shown, in this embodiment, a gear is rotatably connected to one side of the positioning frame, a transmission belt is connected to one side of the gear, a rotating disk is connected to one end of the transmission belt, and one side of the rotating disk is sandpaper.

[0027] Specifically, a gear is provided on one side of the positioning frame. As the positioning frame moves toward the sealing plate, the gear meshes with the rack plate. The gear rotates under the drive of the rack plate. The rotation of the gear drives the transmission belt to rotate, and the transmission belt drives the rotating disk to rotate. The rotation of the rotating disk thus performs a sanding operation on one end of the stainless steel pipe fitting. By using gears and racks to mesh and form a linkage transmission during the movement of the positioning frame, the displacement of the positioning frame can drive the gears to rotate, which in turn drives the rotating disk to rotate via the transmission belt. This achieves synchronous sanding of the ends of stainless steel pipe fittings, allowing the demolding and cleaning processes and end-face sanding processes to be carried out simultaneously. This eliminates the need for a separate grinding station and additional start-stop operations, enhancing the reliability of the equipment and the continuity of production.

[0028] The working principle is as follows: First, during the stainless steel pipe casting process, the first hydraulic cylinder is activated to drive the first guide rail and the upper mold plate downwards, causing the upper and lower mold plates to merge. Then, the second hydraulic cylinder is activated, causing its output end sealing plate to approach the opening of the upper and lower mold plates, thus sealing the mold groove and casting the stainless steel pipe fitting. Molten steel is then poured into a fixed plate, and the molten stainless steel flows along the injection plate into the connecting pipe, and then flows from the injection hole into the mold groove to cast the stainless steel pipe fitting. The sealing plate then... During the process, the rack plate on one side of the sealing plate presses against the fixing plate on one side of the mold plate. The fixing plate moves into the fixing groove to compress the compression spring. After the fixing plate is pressed into the fixing groove, the auxiliary hole at the top of the fixing plate aligns with the positioning hole on the top wall of the fixing groove, and one end of the auxiliary hole aligns with the connecting hole on one side of the rack plate. After casting is completed, the pressure pump inside the machine is started to inject water. The water flows along the positioning hole, auxiliary hole and connecting hole to the water outlet on the sealing plate, and then flows into the fixing hole of the upper mold plate through the water outlet, thereby cooling the upper mold plate and the lower mold plate. The mold closing and sealing plate are driven sequentially by the first and second hydraulic cylinders to achieve mold closure and sealing at the opening, effectively avoiding problems such as molten steel leakage and pipe forming size deviation during casting, thus improving casting forming accuracy and product qualification rate. In addition, the built-in flow channel casting structure allows molten steel to flow into the mold groove through the fixed plate, connecting pipe and injection hole, making the casting process more uniform and smooth, reducing defects such as air porosity and looseness inside the pipe. When the sealing plate is pressed, the rack plate squeezes the fixed plate to compress the compression spring, which can automatically realize the alignment of the positioning hole, auxiliary hole and connecting hole. After casting is completed, the pressure pump injects water into the mold through the preset channel to cool the upper mold plate and the lower mold plate, which greatly shortens the casting cooling and forming cycle and improves the production efficiency and product quality of stainless steel pipe casting. Additionally, with the assistance of the cooling components, after the stainless steel pipe fitting is cast, the second hydraulic cylinder is activated to retract the sealing plate. After the sealing plate retracts, the second guide rail on one side of the sealing plate is activated. The positioning frame on one side of the second guide rail can then clean one end of the sealing plate and the stainless steel pipe fitting. First, the positioning frame moves towards the sealing plate driven by the second guide rail. As the positioning frame approaches the sealing plate, the cutter at the end of the positioning frame pushes along the side of the sealing plate, thereby separating the stainless steel pipe fitting from the sealing plate. In addition, the rotating roller set inside the positioning frame is squeezed by the sealing plate and slides into the rotating groove, so that the rotating roller always fits against the sealing plate. Then, the bottom positioning block is activated. The micro motor built into the positioning block is activated, driving the rotating roller to rotate, so that the rotating roller coats the entire sealing plate with release agent during its movement. After the pipe casting is completed by the cooling assembly, automatic demolding and mold cleaning are achieved in conjunction with the second hydraulic cylinder and the second guide rail. After the sealing plate retracts, the positioning frame moves along the second guide rail, and the end cutter can separate the formed stainless steel pipe from the sealing plate. This avoids pipe deformation, scratches and mold damage caused by manual demolding, ensuring the appearance and dimensional accuracy of the casting. The rotating roller in the positioning frame is squeezed and retracts adaptively, always in close contact with the surface of the sealing plate. With the built-in motor driving the rotation, the release agent can be evenly applied during the movement. There is no need to stop the machine to apply it manually, which simplifies the process and improves the continuity of operation, increases production efficiency, and makes the release agent evenly applied, reducing the risk of subsequent sticking, extending the service life of the mold, and improving the automation level of pipe casting.

A casting cleaning device for stainless steel pipe fittings casting processing according to claim 6, characterized in that: With the assistance of the cooling components, after the stainless steel pipe fitting is cast, the second hydraulic cylinder (2) is activated to drive the sealing plate (21) to retract. After the sealing plate (21) retracts, the second guide rail (28) on one side of the sealing plate (21) is activated. The positioning frame (210) on one side of the second guide rail (28) can then clean the sealing plate (21) and one end of the stainless steel pipe fitting. First, the positioning frame (210) moves towards the sealing plate (21) driven by the second guide rail (28). As the positioning frame (210) approaches the sealing plate (21), the positioning frame (210)... The cutter (217) at the end of the stainless steel pipe is pushed along the side of the sealing plate (21) to separate the stainless steel pipe from the sealing plate (21). In addition, the rotating roller set inside the positioning frame (210) is squeezed by the sealing plate (21) and slides into the rotating groove (212) so that the rotating roller is always in contact with the sealing plate (21). Then the bottom positioning block (216) is started to rotate. The micro motor built into the positioning block (216) is started to drive the rotating roller to rotate, so that the entire sealing plate (21) is coated with release agent during the movement of the rotating roller.

10. A casting cleaning device for stainless steel pipe fittings casting processing according to claim 7, characterized in that: A gear (218) is provided on one side of the positioning frame (210). During the movement of the positioning frame (210) toward the sealing plate (21), the gear (218) meshes with the rack plate (22). The gear (218) rotates under the drive of the rack plate (22). The rotation of the gear (218) drives the transmission belt (219) to rotate. The transmission belt drives the rotating disk (220) to rotate. The rotation of the rotating disk (220) thus performs sanding work on one end of the stainless steel pipe fitting.
