Description

Technical Field

[0001] This invention relates to the field of non-ferrous metal casting technology, and in particular to a gear production mold with impurity removal function. Background Technology

[0002] In the field of gear manufacturing, metal casting has become one of the main processes for mass production of gears due to its high efficiency, low cost and good adaptability to complex structures. Among them, mold casting is the most widely used technical route. This process usually uses precision-machined upper and lower molds. After the two are closed, they form a cavity that closely matches the shape of the target gear. Molten metal (such as various alloy steels, cast iron or non-ferrous metals) is injected into the cavity under pressure or gravity. After cooling and solidification, the mold is opened to obtain the gear casting. Gears cast from non-ferrous metals have advantages such as corrosion resistance, friction reduction and low noise.

[0003] This mature process has long faced a stubborn technical bottleneck in the production of non-ferrous metal gears: before each gear casting, a release agent needs to be sprayed into the mold. After the gear is cast, some of the release agent adheres to the mold. Furthermore, under the repeated washing and thermal cycling of the high-temperature molten metal, the surface of the mold will oxidize. The resulting oxide scale will also cause impurities to adhere to the mold, especially in the part of the gear mold located outside the pitch circle. When cleaning the impurities in this part, each tooth needs to be cleaned in turn, which is a tedious process. If the cleaning is not thorough, it will affect the production quality of subsequent gears. Summary of the Invention

[0004] This invention provides a gear production mold with a cleaning function for testing sealing performance, thereby overcoming the disadvantage that impurities in the tooth area of ​​the mold are difficult to clean.

[0005] The technical solution is as follows: A gear production mold with impurity removal function includes an operating table, a fixed plate on the operating table, a first power module for driving the fixed plate to move longitudinally, a rotating shaft rotatably connected to the fixed plate, a second power module for driving the rotating shaft to rotate on the fixed plate, an upper mold fixedly connected to the rotating shaft, an upper mold having a feed inlet and an exhaust hole, a lower mold fixedly connected to the operating table via a mounting bracket, and circumferentially evenly spaced sliding plates slidably connected to both the upper and lower molds, the evenly spaced sliding plates being fixedly connected to a fixed ring, tension springs being provided between the upper fixed ring and the upper mold and between the lower fixed ring and the lower mold, and a scraper hinged to the side of the sliding plate away from the fixed ring.

[0006] Preferably, the thickness of the outer edge of the scraper is less than the thickness of the middle part.

[0007] Preferably, the scraper is fixedly connected to an arc-shaped plate, the sliding plate is fixedly connected to a semi-circular plate via a support plate, the arc-shaped plate is fixedly connected to a blocking block for limiting the adjacent semi-circular plates, and the sliding plate is provided with a rectangular groove for the adjacent arc-shaped plates to pass through.

[0008] Preferably, the side of the arc-shaped plate away from the adjacent scraper is provided with an arc-shaped surface.

[0009] Preferably, the thickness of the arc-shaped plate gradually increases from the side closest to the adjacent semicircular plate to the side closest to the adjacent scraper, and the semicircular plate is made of an elastic material.

[0010] Preferably, the arc-shaped plate is fixedly connected to a limiting block for pressing adjacent semicircular plates, and the scraper is provided with a magnetic block.

[0011] Preferably, a cleaning component is also included, which is installed on the upper mold and the lower mold. The cleaning component is used to clean impurities on adjacent scrapers. The cleaning component includes two connecting rings symmetrically distributed vertically. The upper connecting ring is fixed to the upper mold, and the lower connecting ring is fixed to the lower mold. Annular airbags are fixed to opposite sides of the two connecting rings. Each annular airbag is provided with circumferentially spaced exhaust pipes that communicate with adjacent annular airbags. The two annular airbags compress each other.

[0012] Preferably, the rotating shaft is rotatably connected to a connecting plate, the connecting plate is fixedly connected to an air storage bladder, the air storage bladder is connected to a connecting pipe, the air storage bladder is connected to the upper annular bladder through a conduit, the conduit passes through the upper connecting ring, a first solenoid valve is provided inside the conduit, and the connecting pipe is used to connect to the feed inlet.

[0013] Preferably, the connecting pipe is slidably connected to a sealing sleeve, a second solenoid valve is provided inside the connecting pipe, and a spring is fixed between the sealing sleeve and the connecting pipe. The sealing sleeve is used to seal the connecting pipe and the feed port.

[0014] Preferably, the connecting plate is fixedly connected with a sealing post for sealing the vent hole of the upper mold.

[0015] The beneficial effects of the present invention using the above structure are as follows: The present invention uses a scraper to uniformly scrape away impurities located on the outer part of the pitch circle of the upper and lower molds, eliminating the need to clean the outer part of the upper and lower molds one by one, thus improving the cleaning efficiency of the upper and lower molds. Furthermore, the mutual compression of the arc plate and the semi-circular plate increases the pressure between the scraper and the upper and lower molds, further improving the cleaning effect on the outer part of the upper and lower molds located on the pitch circle. The mutual compression of the two annular airbags causes the exhaust pipe to discharge gas, blowing off impurities on the adjacent scrapers and cleaning the scrapers. During the mutual compression of the two annular airbags, the air storage airbag is inflated to check whether the upper and lower molds are sealed before casting. Attached Figure Description

Detailed Implementation

[0018] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0019] Example 1

[0020] Currently, impurities on gear molds are typically cleaned by rinsing with water or brushing with a brush. However, when cleaning the part of the mold located outside the pitch circle, it is necessary to clean each tooth of the mold. The cleaning process is tedious, and if the cleaning is not thorough, it will affect the production quality of subsequent gears.

[0021] A gear production mold with impurity removal function, such as Figure 1-Figure 5 and Figure 7As shown, the system includes an operating platform 1, with a fixed plate 2 positioned above it. The operating platform 1 has a first power module that drives the fixed plate 2 to move longitudinally. Two symmetrically distributed connecting frames are fixedly attached to the operating platform 1. The first power module includes an electric slide rail mounted on the connecting frames, with an electric slider slidably connected to the slide rail. Both electric sliders are fixedly connected to the fixed plate 2. A rotating shaft 3 is rotatably connected to the center of the fixed plate 2. The fixed plate 2 also has a second power module for driving the rotating shaft 3 to rotate. The second power module includes a servo motor mounted on the fixed plate 2. The output shaft of the servo motor drives the rotating shaft 3 to rotate via a gear set. The servo motor and its gear set are not shown in the figure. The lower end of the rotating shaft 3 is fixedly connected to... The upper mold 4 has an inlet 401 on its right side and an vent on its left side. Molten metal is injected between the upper mold 4 and the lower mold 5 through the inlet 401, and the gas between the upper mold 4 and the lower mold 5 is discharged through the vent of the upper mold 4. The lower mold 5 is fixed to the operating table 1 by a mounting bracket. Both the upper mold 4 and the lower mold 5 are shells with the same shape. Both the upper mold 4 and the lower mold 5 are slidably connected by circumferentially evenly spaced sliding plates 6. The upper sliding plate 6 is located between two adjacent teeth of the upper mold 4, and the lower sliding plate 6 is located between two adjacent teeth of the lower mold 5. The evenly spaced sliding plates 6 are all fixedly connected to a fixing ring 7. The upper fixing ring 7 is connected to the upper mold 5. Tension springs are provided between molds 4 and between the lower fixing ring 7 and the lower mold 5. A scraper 8 is hinged to the side of the sliding plate 6 away from the fixing ring 7. The shape of the scraper 8 is the same as the shape of the part of the gear teeth located outside the pitch circle after casting. Subsequently, the part of the teeth of the upper mold 4 and the lower mold 5 located outside the pitch circle is named the cleaning area. The thickness of the outer edge of the scraper 8 is less than the thickness of the middle part, which facilitates the scraping of impurities in the cleaning area of ​​the upper mold 4 and the lower mold 5. An arc plate 9 is fixed to the scraper 8. A semi-circular plate 10 is fixed to the sliding plate 6 through the support plate. A blocking block 902 for limiting the adjacent semi-circular plates 10 is fixed to the arc plate 9. The sliding plate 6 is provided with a rectangular groove for the adjacent arc plate 9 to pass through. The arc plate 9 is located away from the fixed ring 7. An arc-shaped surface is provided on one side of the adjacent scraper 8. The thickness of the arc plate 9 gradually increases from the side near the adjacent semi-circular plate 10 to the side near the adjacent scraper 8. The semi-circular plate 10 is made of elastic material. Taking the arc plate 9 of the upper sliding plate 6 as an example, during the counterclockwise rotation of the arc plate 9, the arc plate 9 will gradually squeeze the semi-circular plate 10 and cause the semi-circular plate 10 to deform. The resistance of the counterclockwise rotation of the arc plate 9 increases, so that the right side of the scraper 8 is in close contact with the bottom of the lower mold 5. The arc plate 9 is fixedly connected to a limiting block 901 for squeezing the adjacent semi-circular plate 10. When the scraper 8 is rotated to a horizontal state, the semi-circular plate 10 limits the adjacent arc plate 9 through the adjacent limiting block 901. The scraper 8 is provided with a magnetic block 801.

[0022] In the initial state, the toothed parts of the upper mold 4 and the lower mold 5 are misaligned. The blocking block 902 limits the adjacent semicircular plates 10, causing the scraper 8 to be tilted relative to the adjacent sliding plate 6, as shown in the following state. Figure 5 As shown, when this mold is used to produce gears, the operator first sprays a release agent into the upper mold 4 and lower mold 5 to assist the gears in detaching from the upper mold 4 and lower mold 5 after cooling. After the release agent is sprayed, the operator first moves the fixing plate 2 downward through the first power module. The fixing plate 2 moves the upper mold 4 downward through the rotating shaft 3. The upper mold 4 moves the upper fixing ring 7 and its upper parts downward simultaneously through the tension spring. The scraper 8 on the upper fixing ring 7 gradually enters the adjacent tooth position in the lower mold 5. At the same time, the scraper 8 on the lower fixing ring 7 enters the adjacent tooth position in the upper mold 4. Taking the scraper 8 moving downward on the right as an example, when the scraper 8 contacts the bottom of the lower mold 5, the state is as follows. Figure 4 As shown, at this time, the right side of the scraper 8 first contacts the bottom of the lower mold 5 and is limited by the lower mold 5 and cannot continue to move downward. As the sliding plate 6 continues to drive the left side of the scraper 8 to move downward, the scraper 8 rotates counterclockwise around its left side. The scraper 8 drives the arc plate 9 to rotate counterclockwise around the left side of the scraper 8. Since the thickness of the arc plate 9 gradually increases from the side near the adjacent semicircular plate 10 to the side near the adjacent scraper 8, during the counterclockwise rotation of the arc plate 9, the arc plate 9 will gradually squeeze the semicircular plate 10 and cause the semicircular plate 10 to deform. The resistance of the counterclockwise rotation of the arc plate 9 increases, so that the right side of the scraper 8 is in close contact with the bottom of the lower mold 5. When the sliding plate 6 drives the scraper 8 to move downward, the scraper 8 scrapes away the impurities in the right side of the area to be cleaned in the lower mold 5 and pushes them to the right. Since the thickness of the outer edge of the scraper 8 is less than the thickness of the middle part, the impurities in the right side of the area to be cleaned in the lower mold 5 will move to the upper side of the scraper 8.

[0023] As the arc plate 9 rotates counterclockwise around the left side of the scraper 8, the arc plate 9 drives the limiting block 901 to rotate counterclockwise. When the limiting block 901 is engaged with the left side of the semicircular plate 10, the lower end of the sliding plate 6 contacts the bottom of the lower mold 5. The operator stops the first power module, and the sliding plate 6 no longer moves downward. The scraper 8 is flush with the bottom of the lower mold 5. At this time, the scraper 8 on the lower sliding plate 6 is flush with the top of the upper mold 4. All the impurities in the right side of the lower mold 5 to be cleaned are moved onto the scraper 8. Subsequently, the operator uses the first power module to... The force module drives the fixed plate 2 to move upward. The upward-moving scraper 8 scrapes away the impurities in the area to be cleaned of the lower mold 5 and moves it upward. The scraper 8 on the lower sliding plate 6 scrapes away the impurities in the area to be cleaned of the upper mold 4 and moves it downward. When the upward-moving scraper 8 moves out of the adjacent area to be cleaned of the lower mold 5, the impurities in the areas to be cleaned of the upper mold 4 and the lower mold 5 are scraped away, ensuring the strength of the gear teeth in subsequent production. When the upward-moving scraper 8 is higher than the scraper 8 on the lower sliding plate 6, the operator stops the fixed plate 2 through the first power module.

[0024] After the fixed plate 2 stops moving upward, the operator drives the rotating shaft 3 to rotate via the second power module. The rotating shaft 3 drives the upper mold 4 and the parts on it to rotate. When the projections of the upper mold 4 and the lower mold 5 in the horizontal direction coincide, the operator controls the second power module to stop driving the rotating shaft 3 to rotate. Subsequently, the operator drives the fixed plate 2, the rotating shaft 3, and the upper mold 4 to move downward via the first power module. The upper scraper 8 moves downward. Taking the two scrapers 8 on the right as an example, when the upper scraper 8 contacts the lower scraper 8, the magnetic blocks 801 inside the two scrapers 8 attract each other, as shown in the state. Figure 7 As shown, the two scrapers 8 no longer have relative displacement. As the upper mold 4 continues to move downward, the tension spring on the upper mold 4 is stretched. At the same time, the spring on the lower mold 5 is also stretched. When the upper mold 4 contacts the lower mold 5 and completes the seal, the operator stops the first power module.

[0025] After the upper mold 4 and lower mold 5 are sealed, the operator injects molten metal between the upper mold 4 and lower mold 5 through the feed port 401. Excess gas between the upper mold 4 and lower mold 5 is discharged through the vent of the upper mold 4. When the space between the upper mold 4 and lower mold 5 is filled with molten metal, the operator stops injecting molten metal between the upper mold 4 and lower mold 5. After the molten metal between the upper mold 4 and lower mold 5 cools down, the operator controls the first power module to move the fixed plate 2, rotating shaft 3, and upper mold 4 upward. The tension of the springs on the upper mold 4 and lower mold 5 is gradually released. When the tension of the springs on the upper mold 4 and lower mold 5 returns to its initial state, the upper mold 4 continues to move upward, driving the upper fixed ring 7 and the upper sliding plate 6 upward through its tension springs, so that the right side... Taking two sliding plates 6 as an example, the upper sliding plate 6 drives the upper scraper 8 to move upward. Since the two magnetic blocks 801 attract each other, the left side of the upper scraper 8 will move upward relative to the left side of the lower scraper 8. The right sides of the two scrapers 8 contact and the left sides separate. The upper scraper 8 rotates clockwise around its left side, and the lower scraper 8 rotates counterclockwise around its left side. Taking the upward movement of the right scraper 8 as an example, the scraper 8 drives the arc plate 9 and the limiting block 901 to rotate clockwise around the left side of the scraper 8. After the limiting block 901 presses the semicircular plate 10, the semicircular plate 10 deforms and resets. When the left side of the arc plate 9 is limited by the semicircular plate 10 and cannot continue to rotate clockwise around the left side of the scraper 8, as the upper scraper 8 continues to move upward, the two scrapers 8 separate, and the deflection angle of the scraper 8 relative to the adjacent sliding plate 6 returns to the initial angle.

[0026] When the distance between the upper mold 4 and the lower mold 5 is sufficient to remove the cast gear, the operator controls the first power module to stop moving the upper mold 4 upward. Subsequently, the operator removes the gear from the lower mold 5, completing the production process of one gear. The operator cleans the impurities in the middle of the upper mold 4 and the lower mold 5. When cleaning the impurities in the middle of the upper mold 4 and the lower mold 5, the operator uses a brush or a rotating electric brush. The impurities in the areas to be cleaned in the upper mold 4 and the lower mold 5 need to be cleaned sequentially. Therefore, before the next casting of the gear, the scraper 8 scrapes away the impurities in the areas to be cleaned in the upper mold 4 and the lower mold 5. The arc plate 9 and the semi-circular plate 10 press against each other, increasing the pressure between the scraper 8 and the upper mold 4 and the lower mold 5, thus improving the cleaning effect on the areas to be cleaned in the upper mold 4 and the lower mold 5.

[0027] Example 2

[0028] Based on Example 1, a gear production mold with impurity removal function, such as Figures 2-4 and Figure 6As shown, it also includes a cleaning assembly, which is installed on the upper mold 4 and the lower mold 5. The cleaning assembly is used to clean impurities on adjacent scrapers 8. The cleaning assembly includes two symmetrically distributed connecting rings 11. The upper connecting ring 11 is fixed to the outside of the upper mold 4, and the lower connecting ring 11 is fixed to the outside of the lower mold 5. Annular airbags 12 are fixed to opposite sides of the two connecting rings 11. The thickness of the annular airbags 12 is greater than the thickness of the upper mold 4, ensuring that the two annular airbags 12 are mutually compressed when the upper mold 4 and the lower mold 5 are sealed. The annular airbags 12 are provided with circumferentially evenly spaced exhaust pipes 13. The gas discharged from the exhaust pipes 13 is used to blow off impurities on adjacent scrapers 8. The exhaust pipes 13 are connected to adjacent annular airbags 12. The two annular airbags 12 are mutually compressed. A connecting plate 14 is rotatably connected to the rotating shaft 3. An air storage airbag 15 is fixed to the right side of the connecting plate 14. The lower side of the tube is connected to a connecting pipe 16. In the initial state, the connecting pipe 16 is connected to the feed inlet 401. The air storage bladder 15 is connected to the upper annular air bladder 12 through a conduit 17. The conduit 17 is a flexible tube. The lower side of the conduit 17 passes through the upper connecting ring 11. A first solenoid valve is installed inside the conduit 17. In the initial state, the first solenoid valve is in the open state. The connecting pipe 16 is used to connect to the feed inlet 401. A sealing post for sealing the vent hole of the upper mold 4 is fixedly connected to the left side of the connecting plate 14. When the connecting pipe 16 is connected to the feed inlet 401, the sealing post of the connecting plate 14 seals the vent hole of the upper mold 4. A sealing sleeve 18 is slidably connected to the lower side of the connecting pipe 16. A second solenoid valve is installed inside the connecting pipe 16. In the initial state, the second solenoid valve of the connecting pipe 16 is in the closed state. A spring is fixed between the sealing sleeve 18 and the connecting pipe 16. The sealing sleeve 18 is used to seal the connecting pipe 16 and the feed inlet 401.

[0029] After the scraper 8 removes the impurities from the areas to be cleaned in the upper mold 4 and lower mold 5, the operator still needs to clean the impurities adhering to the scraper 8 in sequence. The cleaning process is tedious. In order to clean the impurities adhering to the scraper 8, the following operations are performed: In the initial state, the sealing column of the connecting plate 14 blocks the vent hole of the upper mold 4, the connecting pipe 16 is connected to the feed port 401, the sealing sleeve 18 seals the connection between the connecting pipe 16 and the feed port 401, the first solenoid valve in the guide tube 17 is in the open state, and the second solenoid valve in the connecting pipe 16 is in the closed state. When the upper scraper 8 enters the lower mold 5 and contacts the bottom of the lower mold 5, the two annular airbags 12 and Before contact, when the upper mold 4 and the lower mold 5 are projected to overlap in the horizontal direction, as the upper mold 4 moves downward, the upper mold 4 drives the upper annular airbag 12 to move downward through the upper connecting ring 11. When the two annular airbags 12 come into contact, the upper mold 4 has not yet come into contact with the lower mold 5. As the annular airbag 12 moves downward, the two annular airbags 12 squeeze each other. Taking the upper annular airbag 12 as an example, part of the gas in the annular airbag 12 is discharged through the exhaust pipe 13, blowing off the impurities on the scraper 8 and cleaning the scraper 8. Another part of the gas in the annular airbag 12 enters the gas storage airbag 15 through the conduit 17 and causes the gas storage airbag 15 to expand.

[0030] After the upper mold 4 and lower mold 5 come into contact and seal with each other, the operator closes the first solenoid valve in the conduit 17 and opens the second solenoid valve in the connecting pipe 16. If the upper mold 4 and lower mold 5 are not completely sealed (impurities or objects stuck on the contact surfaces of the upper mold 4 and lower mold 5 will cause gaps between the upper mold 4 and lower mold 5, affecting the subsequent pouring process), the operator observes that the volume of the air bladder 15 has decreased, indicating that the upper mold 4 and lower mold 5 are not completely sealed. The operator then checks and readjusts the upper mold 4 and lower mold 5 until they reconnect. After contact and sealing, if the volume of the air reservoir 15 remains unchanged, it proves that the sealing process of the upper mold 4 and the lower mold 5 is complete. The operator moves the sealing sleeve 18 upward, and the spring on the sealing sleeve 18 is compressed. When the lower side of the sealing sleeve 18 is higher than the upper surface of the feed inlet 401, the operator rotates the connecting plate 14. The connecting plate 14 drives the air reservoir 15, the connecting pipe 16, the sealing sleeve 18, and the sealing post on the left to rotate. The sealing post of the connecting plate 14 moves away from the exhaust hole of the upper mold 4 and no longer blocks the exhaust hole of the upper mold 4. When the connecting pipe 16 is no longer connected to the feed inlet 401, the operator continues... Continuing the gear casting process, as the upper mold 4 moves upward away from the lower mold 5, the upper mold 4 drives the upper annular airbag 12 upward through the upper connecting ring 11. The two annular airbags 12 no longer press against each other and return to their original positions. External gas enters the adjacent annular airbag 12 through the exhaust pipe 13. After the gear casting is completed, the operator moves the sealing sleeve 18 upward, compressing the spring on the sealing sleeve 18. Then, the connecting plate 14 is rotated in the opposite direction. The connecting plate 14 drives the air storage airbag 15, the connecting pipe 16, the sealing sleeve 18, and the sealing column on the left to rotate in the opposite direction. When the connecting pipe 1... After the connection with the feed inlet 401 is established, the operator releases the sealing sleeve 18. The spring force on the sealing sleeve 18 is released, causing the sealing sleeve 18 to move downward, sealing the connecting pipe 16 and the feed inlet 401. At the same time, the sealing post on the left side of the connecting plate 14 seals the exhaust port of the upper mold 4. The two annular airbags 12 squeeze each other, causing the exhaust pipe 13 to discharge gas, blowing off the impurities on the adjacent scraper 8 and cleaning the scraper 8. During the process of the two annular airbags 12 squeezing each other, the air storage airbag 15 is inflated to check whether the upper mold 4 and the lower mold 5 have been sealed before pouring.
