Description

Technical Field

[0001] This application relates to the field of casting technology, and in particular to a casting forming apparatus for a cover-opening pump seat joint casting. Background Technology

[0002] The cap-opening machine pump seat connector is a connecting component in the hydraulic system of the cap-opening machine, used to connect the hydraulic pump to the pump seat, pipeline, or related fixed structure, and serving to provide installation positioning, oil circuit connection, and sealing support. During the manufacturing process, the cap-opening machine pump seat connector is often formed using a casting method.

[0003] In existing technology, when casting the pump seat connector of the cover-opening machine, two molds are usually closed to form a complete molding cavity. Molten metal is then injected into the molding cavity through the injection port. After the molten metal cools and solidifies, the casting is obtained. The casting is then removed from the molding cavity, and this cycle is repeated to achieve mass casting production.

[0004] However, during continuous casting, mold release agents, metal oxides, carbon deposits, and small amounts of adhered metal debris can easily remain on the inner wall of the mold cavity. As these residues accumulate, the surface quality and dimensional accuracy of the mold cavity gradually decline, leading to problems such as rough surfaces, unclear contours, sticking to the mold, or dimensional deviations in subsequent castings. In severe cases, it can also cause defects such as porosity and shrinkage cavities inside the casting, reducing the casting yield and shortening the mold's service life. Summary of the Invention

A gear is fixedly fitted on the rotating end of the connecting rod 2, and the two gears mesh with each other. A motor 1 for driving the connecting rod 2 on one side to rotate is fixedly mounted on the mounting housing.

[0011] Preferably, the inner cavity of the rigid tube is provided with a motor five for driving the rotating cylinder to rotate, and a lead screw one is threadedly connected to the inner side of the threaded cylinder. One end of the lead screw one is rotatably disposed in the inner cavity of the rotating cylinder, and the inner cavity of the rotating cylinder is provided with a motor four for driving the lead screw one to rotate.

[0012] Preferably, the telescopic plate is threadedly connected to a second lead screw, one end of which is rotatably mounted on an adjustment plate. The adjustment plate is equipped with a second motor for driving the second lead screw to rotate, and the telescopic plate is equipped with a third motor for driving the mounting shell to rotate.

[0013] Preferably, the base is fixedly connected to multiple guide rods, the mounting plate is slidably disposed on the multiple guide rods, the base is provided with a lead screw linear module one along the vertical edge, the mounting plate is fixedly disposed on the moving end of the lead screw linear module one, and the top of the multiple guide rods is fixedly connected to a top plate.

[0014] Preferably, the rigid tube is provided with an annular region elimination component;

[0015] The annular area elimination component includes a conical cover fixedly fitted at the opening of the rigid pipe, the conical cover being made of an elastic material.

[0016] Preferably, the outer wall of the conical cover is uniformly distributed and fixedly connected with multiple traction plates along the circumference, and a sliding rod is fixedly connected to the traction plate. The outer wall of the rigid tube is uniformly distributed and fixedly connected with multiple limiting rods along the circumference. Each sliding rod slides through a limiting rod in the transverse direction. A transmission ring is slidably sleeved on the outer wall of the rigid tube. Multiple connecting rods are uniformly distributed and rotatably connected to the transmission ring along the circumference. The end of each connecting rod away from the transmission ring is rotatably connected to the end of a sliding rod. An electric push rod is fixedly provided on the lifting plate. The piston end of the electric push rod is fixedly connected to one end of the transmission ring.

[0017] Preferably, a rotating plate is fixedly connected to the bottom of the rotating cylinder, and a scraper is slidably inserted into the inner cavity of the rotating plate along the transverse direction. One end of the scraper is fixedly connected to a spring, and the other end of the spring is fixedly connected to the inner wall of the rotating plate.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The casting and forming device for a capping machine pump seat joint casting of the present invention utilizes a cavity maintenance component to realize the automatic cleaning and centralized recycling of residues on the inner wall of the cavity, avoids the continuous accumulation of residues in the cavity, ensures the surface quality and dimensional accuracy of the cavity, reduces the risk of subsequent castings having defects such as surface roughness, unclear contours, sticking to the mold, porosity and shrinkage cavities, improves the casting qualification rate, and extends the service life of the mold.

[0020] 2. The casting and molding device for a cover-opening pump seat connector of the present invention utilizes an adaptive adjustment structure to achieve adaptive adjustment of the copper wire brush position to adapt to the specifications of the lower mold after replacement. This improves the adaptability to different cavity sizes, ensuring that the copper wire brush can still accurately extend into the cavity after mold replacement, guaranteeing that the bristles can effectively adhere to the bottom and sidewalls of the cavity, and ensuring that the cleaning effect does not decrease due to changes in mold specifications. Furthermore, even if the position of the copper wire brush is adapted, the rigid tube can still cover the cavity, thus ensuring that the residue stirred up during the cleaning process is always confined within the relatively closed space formed by the rigid tube and the cavity, preventing residue from splashing outwards, and ensuring that the dust collection and recovery effect is not affected by the adjustment of the copper wire brush position.

[0021] 3. The casting and forming device for a cover-opening pump seat joint of the present invention utilizes an annular area elimination component to simultaneously pull the edge of a conical cover through multiple traction plates, thereby changing the size of the conical cover to match the diameter of the cavity. Then, the conical cover covers the cavity. Since the edge of the conical cover coincides with the edge of the cavity, the conical cover can effectively cover the cavity regardless of whether the diameter of the rigid pipe is larger or smaller than the diameter of the cavity, avoiding exposed areas on the outside of the cavity. This prevents residue buildup on the upper surface of the lower mold due to the mismatch between the rigid pipe and the cavity size, ensuring that the suction airflow is concentrated inside the cavity, improving the suction and removal effect of residues, and ensuring that the upper surface of the lower mold remains clean after cleaning. This facilitates accurate mold closing between the upper and lower molds, thereby improving the casting quality.

[0022] Furthermore, after the conical hood covers the cavity, its conical inner wall can guide and concentrate the rising airflow, causing the airflow containing residue to converge along the inner wall of the conical hood towards the center of the rigid pipe, preventing the airflow from diffusing outward, increasing the flow rate and concentration of the suction airflow, thereby enhancing the ability to trap and remove residue inside the cavity, making the cleaning process more efficient and thorough.

[0023] 4. The casting and molding device for a cap-opening machine pump seat joint as described in this invention ensures that, when the size of the conical cover changes, the scraper remains in close contact with the inner surface of the conical cover under the action of a spring. As the rotating cylinder rotates, the scraper simultaneously scrapes the inner surface of the conical cover, causing residues adhering to the inner wall to fall off. The fallen residues are sucked into the rigid pipe along with the rising airflow and ultimately enter the industrial vacuum cleaner. This prevents the continuous accumulation of residues on the inner surface of the conical cover from affecting the airflow guidance effect and dust collection efficiency, further ensuring the cleanliness of the cavity and the quality of the casting.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0037] Example 1:

[0038] like Figures 1-11 As shown, a casting molding device for a cover-opening pump seat joint casting includes a base 1 and a mounting plate 7. A lower mold 4 is detachably provided on the base 1, and an upper mold 37 is detachably provided on the mounting plate 7. When the lower mold 4 and the upper mold 37 are combined, a complete molding cavity is formed. A cavity maintenance component is provided on the base 1.

[0039] The cavity maintenance assembly includes two copper wire brushes 36 and an industrial vacuum cleaner 3 mounted on a base 1. The air inlet of the industrial vacuum cleaner 3 is connected to a flexible hose 11, and one end of the flexible hose 11 is connected to a rigid tube 16. The rigid tube 16 has an adapter adjustment structure inside for driving the copper wire brushes 36 to move along the cavity.

[0040] In this embodiment, as Figure 2 , Figures 5-7 , Figure 9 As shown, a second linear screw module 8 is provided horizontally along the base 1. A transverse sliding plate 9 is fixedly provided at the moving end of the second linear screw module 8. A third linear screw module 10 is provided vertically along the transverse sliding plate 9. A lifting plate 12 is fixedly provided at the moving end of the third linear screw module 10. A rigid pipe 16 is fixedly provided on the lifting plate 12.

[0041] The adaptive adjustment structure includes a rotating cylinder 22 rotatably disposed inside the rigid tube 16. A threaded cylinder 21 is slidably disposed vertically inside the rotating cylinder 22. An adjustment plate 28 is fixedly connected to the bottom of the threaded cylinder 21. A telescopic plate 31 is slidably inserted into the inner side of the adjustment plate 28. A mounting shell 33 is rotatably disposed at one end of the telescopic plate 31. Two sets of connecting rods are symmetrically disposed on the mounting shell 33 for driving the two copper wire brushes 36 to move.

[0042] The linkage assembly includes two connecting rods 34 rotatably mounted on the mounting housing 33. A connecting rod 35 is rotatably mounted at the end of the connecting rod 34 away from the mounting housing 33. The end of the connecting rod 35 away from the connecting rod 34 is rotatably connected to the copper wire brush 36. A gear 26 is fixedly fitted on the rotating end of the connecting rod 34. The two gears 26 mesh with each other. A motor 27 for driving the rotation of one side of the connecting rod 34 is fixedly mounted on the mounting housing 33.

[0043] The inner cavity of the rigid tube 16 is equipped with a motor 40 for driving the rotating cylinder 22 to rotate. The inner side of the threaded cylinder 21 is threadedly connected to a lead screw 20. One end of the lead screw 20 is rotatably located in the inner cavity of the rotating cylinder 22. The inner cavity of the rotating cylinder 22 is equipped with a motor 39 for driving the lead screw 20 to rotate.

[0044] The telescopic plate 31 is threadedly connected to a second lead screw 29. One end of the second lead screw 29 is rotatably mounted on an adjusting plate 28. The adjusting plate 28 is equipped with a second motor 30 for driving the second lead screw 29 to rotate. The telescopic plate 31 is equipped with a third motor 32 for driving the mounting shell 33 to rotate.

[0045] Multiple guide rods 5 are fixedly connected to the base 1. The mounting plate 7 is slidably mounted on the multiple guide rods 5. A lead screw linear module 6 is provided vertically along the upper edge of the base 1. The mounting plate 7 is fixedly mounted on the moving end of the lead screw linear module 6. The top of the multiple guide rods 5 is fixedly connected to a top plate 2.

[0046] Specifically, the cover-opening pump seat joint casting in this embodiment is a cylindrical structure, and this type of cover-opening pump seat joint is quite common.

[0047] By using the lead screw linear module 6 to drive the mounting plate 7 to slide on multiple guide rods 5, the upper mold 37 can be moved up and down, allowing the upper mold 37 to merge or separate from the lower mold 4.

[0048] When the upper mold 37 and the lower mold 4 are combined, they work together to form a complete molding cavity. Then, molten metal is injected into the molding cavity through the injection port on the upper mold 37. After the molten metal cools and solidifies, the casting can be obtained.

[0049] Next, the upper mold 37 separates from the lower mold 4, and the casting is removed from the cavity.

[0050] Before the next casting operation begins, the linear actuator 8 drives the transverse plate 9 to move laterally, moving the rigid tube 16 above the lower mold 4, with the rigid tube 16 aligning with the cavity axis. Then, the linear actuator 10 drives the lifting plate 12 to descend, allowing the two copper wire brushes 36 to simultaneously extend into the cavity, with the bristles of the copper wire brushes 36 adhering to the inner wall of the cavity. At this time, the rigid tube 16 covers the top of the cavity. Then, motors 32 and 40 are simultaneously activated, causing the mounting shell 33 to rotate both on its own axis and around the central axis, thus cleaning the residue in the cavity. Simultaneously, industrial vacuuming is activated. When machine 3 starts, the raised residue is sucked into the dust box of industrial vacuum cleaner 3 through rigid pipe 16 and flexible pipe 11. Since rigid pipe 16 is attached to the upper surface of lower mold 4 and covers the cavity, the raised residue will not splash to the surrounding area, but can only enter the dust box along the pipe. This realizes automatic cleaning and centralized collection of residue on the inner wall of the cavity, avoids the continuous accumulation of residue in the cavity, ensures the surface quality and dimensional accuracy of the cavity, reduces the risk of defects such as surface roughness, unclear contours, sticking, porosity and shrinkage cavities in subsequent castings, improves the casting qualification rate, and extends the service life of the mold.

[0051] In addition, since both the lower mold 4 and the upper mold 37 are detachable, after replacing the lower mold 4 and the upper mold 37, the cavity can be covered by the rigid tube 16 first. Then, the motor 20 drives the lead screw 29 to rotate, so that the telescopic plate 31 slides inside the adjusting plate 28, making the mounting shell 33 aligned with the cavity. Subsequently, according to the depth of the cavity, the motor 49 drives the lead screw 1 to rotate, so that the threaded cylinder 21 slides inside the rotating cylinder 22, causing the two copper wire brushes 36 to descend and extend into the cavity, so that the bristles on the copper wire brushes 36 fit against the bottom of the cavity. Then, according to the width of the cavity, the motor 127 drives the connecting rod 24 on one side to rotate, so that multiple connecting rods 24 can rotate simultaneously under the transmission of the two gears 26. Through the connecting rods 24 and 35, the two copper wire brushes 36 move laterally at the same time, so that the bristles of the copper wire brushes 36 fit against the side wall of the cavity.

[0052] This completes the adaptation adjustment of the copper wire brush 36's position to accommodate the changed lower mold 4 specifications, thereby improving its adaptability to different cavity sizes. This ensures that the copper wire brush 36 can still accurately extend into the cavity after mold replacement, guaranteeing that the bristles effectively conform to the bottom and sidewalls of the cavity, and ensuring that the cleaning effect does not decrease due to changes in mold specifications. Furthermore, even with the adaptation adjustment of the copper wire brush 36's position, the rigid tube 16 still covers the cavity, ensuring that any residue stirred up during cleaning is always confined within the relatively closed space formed by the rigid tube 16 and the cavity, preventing residue from splashing outwards and ensuring that the dust collection effect is not affected by the adjustment of the copper wire brush 36's position.

[0053] Example 2:

[0054] In this embodiment, as Figures 2-4 , Figure 11 As shown, the rigid tube 16 is provided with an annular area elimination component;

[0055] The annular area elimination component includes a conical cover 15 fixedly sleeved at the opening of the rigid tube 16, the conical cover 15 being made of elastic material.

[0056] Multiple traction plates 19 are evenly distributed and fixedly connected to the outer wall of the conical cover 15. Slide rods 18 are fixedly connected to the traction plates 19. Multiple limiting rods 38 are evenly distributed and fixedly connected to the outer wall of the rigid tube 16. Each slide rod 18 slides laterally through a limiting rod 38. A transmission ring 14 is slidably sleeved on the outer wall of the rigid tube 16. Multiple connecting rods 17 are evenly distributed and rotatably connected to the transmission ring 14. The end of each connecting rod 17 away from the transmission ring 14 is rotatably connected to the end of a slide rod 18. An electric push rod 13 is fixedly provided on the lifting plate 12. The piston end of the electric push rod 13 is fixedly connected to one end of the transmission ring 14.

[0057] Specifically, in the above embodiments, although the cavity can be covered by the rigid tube 16 during residue adsorption to prevent residue from splashing outwards and thus ensure adsorption effect, when the cavity diameter is smaller than the rigid tube 16 diameter, there will be a certain gap between the cavity edge and the inner wall of the rigid tube 16, resulting in a portion of the upper surface of the lower mold 4 being within the coverage area of ​​the rigid tube 16. During residue adsorption, some of the lifted residue easily falls into this area and adheres to the upper surface of the lower mold 4. Since this area is located outside the cavity, within the annular space between the inner wall of the rigid tube 16 and the cavity edge, the suction airflow mainly flows along the inside of the cavity and the central channel of the rigid tube 16, resulting in a weak suction effect on this annular edge area. Therefore, the residue adhering to the upper surface of the lower mold 4 cannot be effectively sucked in. As the residue in this area continues to accumulate, it will gradually form a buildup on the upper surface of the lower mold 4, affecting the fitting accuracy of the upper mold 37 and the lower mold 4 when they are closed, thereby reducing the casting quality. When the diameter of the rigid tube 16 is smaller than the diameter of the cavity, it cannot cover the cavity, which also affects the normal cleaning of the cavity and the adsorption of residues.

[0058] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0059] Based on the changed cavity diameter, the electric actuator 13 drives the transmission ring 14 to slide vertically along the outer wall of the rigid tube 16, causing multiple connecting rods 17 to rotate simultaneously. Each connecting rod 17 then drives its corresponding sliding rod 18 to slide laterally on the limiting rod 38. This allows multiple traction plates 19 to simultaneously pull the edge of the conical cover 15, thereby changing the size of the conical cover 15 to match the cavity diameter. The conical cover 15 then covers the cavity. Since the edge of the tube 16 coincides with the edge of the cavity, the conical cover 15 can effectively cover the cavity regardless of whether the diameter of the tube 16 is larger or smaller than the cavity diameter, thus preventing exposed areas on the outside of the cavity. This ensures that no residue accumulates on the upper surface of the lower mold 4 due to the mismatch between the tube 16 and the cavity size, and ensures that the suction airflow is concentrated inside the cavity, improving the suction and removal effect of residues. This also ensures that the upper surface of the lower mold 4 remains clean after cleaning, which is conducive to the accurate mold closing of the upper mold 37 and the lower mold 4, thereby improving the casting quality.

[0060] Furthermore, after the conical hood 15 covers the cavity, its conical inner wall can guide and concentrate the rising airflow, causing the airflow containing residue to converge along the inner wall of the conical hood 15 towards the center of the rigid pipe 16, preventing the airflow from diffusing outward, increasing the flow rate and concentration of the suction airflow, thereby enhancing the ability to trap and extract residue inside the cavity, making the cleaning process more efficient and thorough.

[0061] Example 3:

[0062] like Figure 8 and Figure 10 As shown, a rotating plate 23 is fixedly connected to the bottom of the rotating cylinder 22. A scraper 25 is slidably inserted into the inner cavity of the rotating plate 23 along the transverse direction. A spring 24 is fixedly connected to one end of the scraper 25, and the other end of the spring 24 is fixedly connected to the inner wall of the rotating plate 23.

[0063] Specifically, in the above embodiments, although the conical cover 15 can cover the cavity and guide and concentrate the rising airflow, because the conical cover 15 is made of elastic material, its inner surface is prone to adhering to impurities such as release agent and metal dust after prolonged contact with residues and airflow. Furthermore, the elastic material itself has a certain degree of adhesion, making it easier for residues to adhere to its inner wall, resulting in the gradual accumulation of dirt on the inner surface of the conical cover 15, affecting the airflow guidance effect and dust collection efficiency. If not cleaned for a long time, the already adhered residues may fall back into the cavity, affecting the cleanliness of the cavity and the quality of the casting.

[0064] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0065] When the dimensions of the conical shroud 15 change, the scraper 25 remains in close contact with the inner surface of the conical shroud 15 under the action of the spring 24. As the rotating cylinder 22 rotates, the scraper 25 simultaneously scrapes the inner surface of the conical shroud 15, causing residues adhering to the inner wall to fall off. The fallen residues are drawn into the rigid pipe 16 along with the rising airflow and ultimately enter the industrial vacuum cleaner 3. This prevents the continuous accumulation of residues on the inner surface of the conical shroud 15 from affecting the airflow guidance effect and vacuuming efficiency, further ensuring the cleanliness of the cavity and the quality of the casting.
