Description

Technical Field

[0001] This invention relates to the technical field of casting equipment, and in particular to a cam bearing cover casting device and its usage method. Background Technology

[0002] A camshaft bearing cap is a component used to fix and support a camshaft. It is mainly used to ensure the coaxiality and stability of the camshaft during high-speed operation. Camshaft bearing caps are usually manufactured with the assistance of casting equipment to improve the casting efficiency.

[0003] Currently, casting equipment employs various methods to cast cam bearing covers. For example, a flip casting mold for an automotive cam front bearing cover, with publication number CN221515998U, belongs to the field of aluminum alloy casting technology. It includes a base, with a casting table fixedly connected to the upper surface of the base. The upper surface of the casting table has a groove, and the inner wall of the groove has four mounting slots. Each mounting slot has a compression spring fixedly connected to its inner wall, and a compression plate is fixedly connected to one end of each of the four compression springs that are close to each other.

[0004] In existing casting equipment, when casting cam bearing caps, the casting liquid is usually cooled and formed by natural cooling with vent holes. This cooling efficiency is low and cannot achieve efficient casting of cam bearing caps. For example, in the aforementioned prior art, the equipment only uses vent holes to release the hot gas from the molten liquid. This heat dissipation method is inefficient and requires a long waiting time. At the same time, the equipment does not treat the air bubbles in the molten liquid during the pouring process, resulting in a large number of air bubbles in the formed cam bearing cap and poor quality of the formed part.

[0005] Therefore, there is an urgent need to design a cam bearing cover casting device and its usage method to solve the above problems. Summary of the Invention

[0030] 3. When casting cam bearing caps, this casting device can simultaneously achieve heat absorption and cooling of the upper and lower casting molds by using a condensate circulation method.

It can also directly blow air to dissipate heat from the lower casting mold, thereby rapidly dissipating heat from the lower casting mold and effectively improving the cooling and forming efficiency of the casting liquid.

[0032] In summary, this invention can effectively remove air bubbles in the casting liquid by using micro-vibration during the casting process, thus preventing pores from appearing in the molded cam bearing cover.

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0053] Example 1: Refer to Figures 1-3 A cam bearing cover casting device includes a casting base 1 and a casting box 7 for casting cam bearing covers disposed on the casting base 1. The casting base 1 is used to place and support the casting box 7 to achieve stable casting of the cam bearing cover.

[0054] This casting apparatus also includes:

[0055] A lifting assembly is installed on the casting box 7. The upper casting mold 12 is installed inside the lifting assembly. The lifting assembly is used to lift the upper casting mold 12. The upper casting mold 12 is equipped with a pouring pipe 11 for pouring casting liquid.

[0056] The casting pipe 11 is connected to the casting liquid input pipe, which is used to input the casting liquid into the upper casting mold 12 to realize the casting of the cam bearing cover.

[0057] The casting unit is set inside the casting box 7. The casting unit is used to cast the cam bearing cover. At the same time, it removes air bubbles in the casting liquid during the pouring process, improves the density and flow rate of the liquid, and effectively removes the pores in the cam bearing cover after molding.

[0058] The casting unit uses a combination of air cooling and liquid cooling to efficiently cool the casting liquid after casting, thereby improving the cooling and forming efficiency of the cam bearing cover.

[0059] The casting base 1 is equipped with a protective shield 2 for shielding, and the casting base 1 is equipped with a lifting assembly and a control panel 3 for controlling the operation of the casting unit. The control panel 3 automatically controls the flexible operation of the lifting assembly and the casting unit to realize automated casting.

[0060] Example 2: Refer to Figures 1-3 The difference between this embodiment and embodiment one is that the lifting assembly includes multiple limiting slide rods 8 fixedly installed on the casting box 7, and a fixed top plate 6 is fixedly installed on the upper part of the multiple limiting slide rods 8, and a control box 4 for controlling the operation of the entire device is provided on the fixed top plate 6.

[0061] The control box 4 is used in conjunction with the control panel 3 to improve the control precision of the lifting assembly and the casting unit, realize the automatic pouring and cooling of the cam bearing cover, and improve the efficiency and precision of casting.

[0062] A hydraulic drive rod 5 is installed through the fixed top plate 6. A sliding lifting plate 9 is slidably installed in the middle of multiple limit slide rods 8. The upper part of the sliding lifting plate 9 is fixedly installed on the drive end of the hydraulic drive rod 5. The casting upper mold 12 is fixedly installed on the lower part of the sliding lifting plate 9.

[0063] When the hydraulic drive rod 5 is started, it will drive the sliding lifting plate 9 below it to rise and fall, which in turn can drive the upper casting mold 12 to rise and fall.

[0064] Multiple limiting slide bars 8 serve to limit the sliding lifting plate 9, ensuring that the sliding lifting plate 9 can only move vertically and stably without deviating.

[0065] Example 3: Refer to Figures 3-8 The difference between this embodiment and embodiment two is that the casting unit includes a micro-vibration component and a cooling component. The micro-vibration component is used to improve the density and flow rate of the original liquid during pouring, and the cooling component is used to improve the cooling and molding speed of the original liquid after pouring.

[0066] The micro-vibration component is provided with a lower casting mold 17 that cooperates with the upper casting mold 12, and both the upper casting mold 12 and the lower casting mold 17 are provided with a forming cavity 13 for forming the cam bearing cover.

[0067] A bearing plate 19 is fixedly installed inside the casting box 7. A micro-vibration table 10 is fixedly installed on the bearing plate 19, and the lower casting mold 17 is slidably installed inside the micro-vibration table 10. This allows the lower casting mold 17 to undergo fine reciprocating vertical vibration within the micro-vibration table 10, thereby improving the filling density of the casting liquid inside.

[0068] During casting, the hydraulic drive rod 5 is activated to drive the sliding lifting plate 9 to descend, which in turn drives the upper casting mold 12 to move down and engage with the lower casting mold 17. At this time, the lower casting mold 17 and the forming cavity 13 in the upper casting mold 12 will form a whole, that is, form the shape of the cam bearing cover.

[0069] Multiple positioning pins 14 are fixedly installed on the upper casting mold 12, and multiple positioning holes 16 that cooperate with the positioning pins 24 are opened on the lower casting mold 17. When the upper casting mold 12 moves down, the multiple positioning pins 14 on it will engage with the multiple positioning holes 16 in the lower casting mold 17, thus completing the tight engagement and fixation between the upper casting mold 12 and the lower casting mold 17.

[0070] The outlet end of the pouring pipe 11 is connected to the forming cavity 13 in the upper casting mold 12, and a control valve is installed inside it. After the lower casting mold 17 and the upper casting mold 12 are engaged, the casting liquid can be poured into the forming cavity 13 in the upper casting mold 12 and the lower casting mold 17 through the pouring pipe 11. After the casting liquid is filled, the control valve can be closed to isolate the pouring pipe 11 from the forming cavity 13 in the upper casting mold 12 and complete the isolation of the pouring liquid. At this time, the pouring liquid in the forming cavity 13 in the lower casting mold 17 and the upper casting mold 12 cools and solidifies to form the cast cam bearing cover.

[0071] Example 4: Refer to Figures 4-16 The difference between this embodiment and embodiment three is that the casting unit includes a servo motor 18 fixedly installed in the casting box 7, and a drive roller 22 is fixedly installed on the drive end of the servo motor 18. When the servo motor 18 is started, it will drive the drive roller 22 to rotate, so the speed and direction of rotation of the drive roller 22 can be controlled by the servo motor 18.

[0072] The micro-vibration assembly also includes a rotating disk 24 fixedly mounted on the drive roller 22, and a pushing mechanism is provided on the rotating disk 24. The pushing mechanism includes a lifting limit box 23 provided in the casting box 7, and a sliding seat 28 is slidably mounted in the lifting limit box 23. A pushing rod 26 that cooperates with the bottom of the casting lower mold 17 is fixedly mounted on the upper part of the sliding seat 28. An eccentric drive rod 29 is fixedly mounted on the rotating disk 24. A positioning shaft is fixedly mounted on the lower part of the sliding seat 28, and a traction rod 30 is rotatably mounted between the positioning shaft and the eccentric drive rod 29.

[0073] When pouring the casting liquid, the servo motor 18 is started to drive the drive roller 22 to rotate. The rotation of the drive roller 22 will drive the rotating disk 24 to rotate, which in turn will drive the eccentric drive rod 29 on it to rotate. Since the eccentric drive rod 29 is rotatably connected to the positioning shaft through the traction rod 30, when the eccentric drive rod 29 rotates from the upper part to the lower part, it will pull the traction rod 30 to move down, which will drive the positioning shaft and the sliding seat 28 to move down. When the eccentric drive rod 29 rotates from the lower part to the upper part, it will pull the traction rod 30 to move up, which will drive the positioning shaft and the sliding seat 28 to move up. The continuous rotation of the rotating disk 24 can realize the reciprocating lifting and lowering of the sliding seat 28, so that the sliding seat 28 can reciprocate within the lifting limit box 23.

[0074] Multiple micro-vibration springs 25 for vibration are fixedly installed between the micro-vibration table 10 and the lower casting mold 17. An exhaust pipe is provided on the upper casting mold 12. When the sliding seat 28 moves upward, it will drive the push rod 26 to move upward and lift the lower casting mold 17. At this time, multiple micro-vibration springs 25 will be stretched. When the sliding seat 28 moves downward, the push rod 26 separates from the lower casting mold 17. At this time, multiple micro-vibration springs 25 will automatically retract and reset, thereby driving the lower casting mold 17 to move downward. Repeating the above steps can realize the reciprocating lifting and lowering vibration of the lower casting mold 17.

[0075] While the casting liquid is being poured, the micro-vibration components can be used to reciprocate the micro-vibration of the lower casting mold 17, which can vibrate and compact the casting liquid inside, making the casting liquid fill more tightly. At the same time, the air in the casting liquid can be shaken out and discharged through the exhaust pipe, thereby effectively improving the density of the casting liquid and eliminating the porosity in the cam bearing cover after molding.

[0076] In a further embodiment, a water-cooled box 20 filled with condensate is provided in the cooling assembly, and a drive roller 22 passes through the water-cooled box 20 and is rotatably connected to the water-cooled box 20. Multiple upper cooling pipes 15 and lower cooling pipes 32 for condensate flow are respectively provided in the upper casting mold 12 and the lower casting mold 17.

[0077] The cooling assembly includes a water-cooled box 20 fixedly installed inside the casting box 7. A partition plate 36 is fixedly installed inside the water-cooled box 20, and condensate is filled between the partition plate 36 and the right side wall of the water-cooled box 20. The partition plate 36 is used to separate the condensate so that the condensate can only be stored on the right side of the partition plate 36. A water guiding mechanism and an air guiding mechanism are provided inside the water-cooled box 20.

[0078] The water guiding mechanism includes a pressure plate 38 that is slidably installed between the partition plate 36 and the side wall of the water cooling box 20 away from the drive roller 22. The side wall of the lifting limit box 23 is provided with a lifting groove. The sliding seat 28 passes through the lifting groove and is fixedly installed with a linkage lifting frame 27. The lower end of the linkage lifting frame 27 is fixedly installed on the pressure plate 38. Two elastic water guiding pipes 33 are fixedly installed in the water cooling box 20 for water supply and water return respectively. Both elastic water guiding pipes 33 are slidably connected to the pressure plate 38. One-way valves are provided in both elastic water guiding pipes 33 for the upward pressure of condensate and the downward return of condensate respectively.

[0079] When the sliding seat 28 is raised or lowered, it will drive the linkage lifting frame 27 to rise or fall. When the linkage lifting frame 27 is raised or lowered, it will drive the pressure plate 38 to rise or fall. When the pressure plate 38 moves down, it will squeeze the condensate at the bottom and force it out through the elastic water guide pipe 33 used for water supply, thus realizing the automatic discharge of condensate.

[0080] A water guide tube is fixedly installed inside the upper casting mold 12, and the water guide tube is fixedly connected to multiple upper cooling pipes 15. A water distribution pipe 34 is fixedly installed inside the lower casting mold 17, and the water distribution pipe 34 is connected to two elastic water guide pipes 33. The water distribution pipe 34 is fixedly connected to multiple lower cooling pipes 32. Each lower cooling pipe 32 is provided with a connecting pipe port that cooperates with the corresponding upper cooling pipe 15.

[0081] The upper cooling pipes 15 located on both sides of the water guide tube are used for water inlet and water return, respectively. The lower cooling pipes 32 located on both sides of the water distribution pipe 34 are used for water inlet and water return, respectively. The upper cooling pipe 15 used for water inlet and the lower cooling pipe 32 used for water inlet are interlocked and connected. The upper cooling pipe 15 used for water return and the lower cooling pipe 32 used for water return are interlocked and connected.

[0082] When the upper casting mold 12 and the lower casting mold 17 are engaged, the multiple upper cooling pipes 15 on the upper casting mold 12 will be engaged into the corresponding connecting pipes 32, so that the multiple upper cooling pipes 15 are connected to the corresponding multiple lower cooling pipes 32.

[0083] The condensate pumped out by the upward flexible water guide pipe 33 enters the water distribution pipe 34 and flows into multiple lower cooling pipes 32 for water supply. The condensate in the lower cooling pipes 32 enters the upper cooling pipe 15 for water supply in the upper casting mold 12 through the connecting pipe. The condensate in the upper cooling pipe 15 enters the water guide cylinder and then enters the upper cooling pipe 15 for water discharge. It then enters multiple lower cooling pipes 32 for water recovery through the upper cooling pipe 15, and finally returns to the water cooling box 20 through the water distribution pipe 34 and the flexible water guide pipe 33 for water return, thus completing the condensate circulation.

[0084] With the help of the water guiding mechanism, the condensate can circulate in the lower casting mold 17, the upper casting mold 12 and the water cooling box 20. During the circulation, the heat in the lower casting mold 17 and the upper casting mold 12 can be absorbed and carried away, thereby achieving rapid cooling of the casting liquid and improving the cooling efficiency.

[0085] In a further embodiment, the air guiding mechanism includes an impeller 35 fixedly installed on the part of the drive roller 22 located inside the water-cooled box 20, and an air-guiding mesh plate 39 for supplementing air is provided on the side wall of the water-cooled box 20 near the drive roller 22. Two condensing spiral tubes 37 for guiding air are fixedly connected between the partition plate 36 and the side wall of the water-cooled box 20 away from the drive roller 22, and the two condensing spiral tubes 37 are respectively located at the lower part of two elastic water guiding tubes 33. The two condensing spiral tubes 37 are fixedly connected to the micro-vibration table 10 by an air-guiding pipe 31 for upward airflow.

[0086] When the servo motor 18 drives the drive roller 22 to rotate, the drive roller 22 will drive the impeller 35 to rotate. When the impeller 35 rotates, it will draw in cold air through the air intake screen 39 and discharge it through the condenser spiral tube 37. Since the condenser spiral tube 37 is located in the condensate, it can absorb and remove the heat in the condensate during ventilation, thereby realizing the automatic heat absorption and cooling of the condensate, thus reducing the temperature of the condensate and preventing it from overheating, thereby further improving the heat absorption and cooling effect of the condensate and improving the water cooling effect.

[0087] The micro-vibration stage 10 is provided with multiple exhaust holes 21 for ventilation, and the casting box 7 is provided with multiple ventilation openings for heat exchange. The air discharged from the condenser spiral tube 37 is injected into the micro-vibration stage 10 through the air duct 31, which can directly blow air to cool the lower part of the casting mold 17, thereby further improving the cooling efficiency of the casting mold 17. The air in the micro-vibration stage 10 is discharged through the exhaust holes 21 and replaced by air through the ventilation openings, thereby effectively improving the heat exchange rate between the micro-vibration stage 10, the casting box 7 and the external cold air, realizing efficient heat dissipation of the micro-vibration stage 10 and the casting box 7, further improving the overall heat dissipation efficiency, and increasing the cooling and forming speed of the cam bearing cover.

[0088] Simultaneous vibration of the lower mold 17 during water cooling and air cooling can increase the flow rate of condensate and the airflow rate through vibration, thereby further improving the heat dissipation rate within the mold without affecting the normal operation of the air cooling and water cooling processes.

[0089] The working principle of this casting device is as follows:

[0090] During casting, the hydraulic drive rod 5 is activated to lower the sliding lifting plate 9, which in turn moves the upper casting mold 12 downward and engages with the lower casting mold 17. At this time, the lower casting mold 17 and the forming cavity 13 in the upper casting mold 12 become a whole. After the lower casting mold 17 and the upper casting mold 12 are engaged, the casting liquid is poured into the forming cavity 13 in the upper casting mold 12 and the lower casting mold 17 through the pouring pipe 11. After the casting liquid is filled, the control valve is closed to isolate the pouring pipe 11 from the forming cavity 13 in the upper casting mold 12, thus blocking the pouring liquid. At this time, the pouring liquid in the forming cavity 13 in the lower casting mold 17 and the upper casting mold 12 cools and solidifies, which is the cast cam bearing cover.

[0091] When pouring the casting liquid, the servo motor 18 is started to drive the drive roller 22 to rotate. With the cooperation of the micro-vibration component, the casting lower mold 17 is reciprocated and vibrated, which can vibrate and compact the casting liquid inside, making the casting liquid fill more tightly. At the same time, the air in the casting liquid can be shaken out and discharged through the exhaust pipe, thereby effectively improving the density of the casting liquid and eliminating the air holes in the cam bearing cover after molding.

[0092] When the micro-vibration component is activated, it will drive the sliding seat 28 to rise and fall. When the sliding seat 28 rises and falls, it will drive the linkage lifting frame 27 to rise and fall. When the linkage lifting frame 27 rises and falls, it will drive the pressure plate 38 to rise and fall. When the pressure plate 38 moves down, it will squeeze the condensate at the bottom and force it out through the elastic water guide pipe 33 used for water supply, thus realizing the automatic discharge of condensate.

[0093] Furthermore, with the assistance of the water guiding mechanism, the condensate can circulate within the lower casting mold 17, the upper casting mold 12, and the water cooling box 20. During circulation, the heat in the lower casting mold 17 and the upper casting mold 12 can be absorbed and carried away, thereby achieving rapid cooling of the casting liquid and improving cooling efficiency.

[0094] When the servo motor 18 drives the drive roller 22 to rotate, the drive roller 22 will drive the impeller 35 to rotate. When the impeller 35 rotates, it will draw in cold air through the air intake screen 39 and discharge it through the condenser spiral tube 37. Since the condenser spiral tube 37 is located in the condensate, it can absorb and remove the heat in the condensate during ventilation, thereby realizing the automatic heat absorption and cooling of the condensate, thus reducing the temperature of the condensate and preventing it from overheating, thereby further improving the heat absorption and cooling effect of the condensate and improving the water cooling effect.

[0095] The air drawn out from the condenser spiral tube 37 is injected into the micro-vibration stage 10 through the air duct 31, which can directly blow air to cool the lower part of the casting mold 17, thereby further improving the cooling efficiency of the casting mold 17. The air in the micro-vibration stage 10 is discharged through the exhaust hole 21 and replaced by air through the ventilation opening, thereby effectively improving the heat exchange rate between the micro-vibration stage 10, the casting box 7 and the external cold air, realizing efficient heat dissipation of the micro-vibration stage 10 and the casting box 7, further improving the overall heat dissipation efficiency, and increasing the cooling and forming speed of the cam bearing cover.

[0096] This invention also provides a method for using a cam bearing cap casting apparatus, which includes the following steps:

[0097] S1. When casting the cam bearing cover, start the lifting assembly to drive the upper casting mold 12 to move down and engage it with the lower casting mold 17 inside the casting box 7.

[0098] S2. Start the pouring pipe 11 to pour the casting liquid into the forming cavity 13 inside the upper casting mold 12 and the lower casting mold 17;

[0099] S3. While the casting liquid is being poured, the micro-vibration assembly is activated to perform micro-vibration on the upper casting mold 12 and the lower casting mold 17 to improve the density and flow rate of the liquid.

[0100] S4. After pouring is completed, the cooling components are activated to cool the pouring liquid in the upper casting mold 12 and the lower casting mold 17 with water and air, thereby increasing the cooling and forming speed of the cam bearing cover.

[0101] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
