Description

Technical Field

[0001] The invention belongs to the technical field of demoulding mechanisms, and in particular relates to a rapid demoulding mechanism for castings with complex shapes. Background Art

[0002] The die-casting island is a die-casting operation area formed in the die-casting operation site. It is an important link in the die-casting process. It is usually composed of a die-casting machine, mold, lubrication system, cooling system, furnace and auxiliary equipment. These equipment and tools together constitute a complete production system for injecting molten metal into the mold to form castings.

[0003] For example, the national patent publication number CN211518384U discloses a demoulding plate for a demoulding device, comprising a base plate, a hydraulic cylinder, a constraint plate, a push rod, a push rod, a demoulding base plate, an aluminum alloy plate, a push rod hole, a liquid cooling pipe, a support plate, a water tank, a booster pump 1, a conduit 1, a conduit 2 and a conduit 3, the other end of the conduit 3 extending to the inside of the water tank, a mold opening agent box is provided on the side of the constraint plate away from the booster pump 1, a booster pump 2 is provided on the upper end of the mold opening agent box, a conduit 4 is provided on one side of the booster pump 2, a conduit 5 is provided on the other side of the booster pump 2, the other end of the conduit 4 extends to the lower end of the mold opening agent box, a mold opening agent pipe is provided at the front end of the push rod hole of the demoulding base plate, the other end of the conduit 5 extends to the inside of the demoulding base plate and is connected with the mold opening agent pipe, and a spray hole for cooperating with the mold opening agent pipe is provided on the demoulding base plate and the aluminum alloy plate. Compared with the prior art, the advantages are: easy operation, liquid cooling and improved demoulding effect.

[0004] However, the conventional device still has the following problems when used:

[0005] Liquid cooling is used to cool the demolding plate to accelerate cooling and improve demolding effect. However, due to the liquid flow impact characteristics, the liquid flow rate at the center of the water flow layer will be faster than the liquid flow rate at the surrounding areas that are close to the inner wall of the condenser. Different flow rates will lead to insufficient heat exchange in the condenser. There is a possibility that the liquid at the center of the water flow layer may not be able to completely exchange heat with the inner wall of the condenser. Therefore, the performance of the condenser mechanism can be further improved, so that complex-shaped castings can be demolded more quickly. Summary of the invention

DETAILED DESCRIPTION

[0035] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For example, see Figures 1 to 14The present invention provides a technical solution: a rapid demoulding mechanism for castings of complex shapes, comprising a die-casting frame 1, a top outer wall of one side of the die-casting frame 1 is fixedly connected to a support column 2, a top outer wall of the support column 2 is fixedly connected to a top plate hydraulic press 3, a top outer wall of the top plate hydraulic press 3 is fixedly connected to a feeder 4, an outer wall of one side of the feeder 4 is fixedly connected to a melting furnace, a bottom of the feeder 4 is fixedly connected to a feeder telescopic pipe 7 through the outer wall of the top plate hydraulic press 3, a hydraulic rod 5 is fixedly connected to the bottom outer wall of the top plate hydraulic press 3, an upper die seat 6 is fixedly connected to the bottom outer wall of the hydraulic rod 5, the feeder 4 is connected to the bottom inner wall of the upper die seat 6 through the feeder telescopic pipe 7, a guide rail 9 is fixedly installed on the inner wall of the die-casting frame 1, an outer wall of the guide rail 9 is slidably connected to an electric control guide table 10, a lower die seat 13 is provided on the top outer wall of the electric control guide table 10, and a top outer wall of the lower die seat 13 is movably clamped with the bottom outer wall of the upper die seat 6 Next, the inner wall of the electric control platform 10 is also provided with a circulating water cooling mechanism, and a central control console 8 is fixedly installed on the outer wall of one side of the die-casting frame 1. The circulating water cooling mechanism includes a refrigerator 34, two flow pipes 35, multiple groups of outer rotating rods 15 and fan blades 16. A condensation channel 14 is opened on the top outer wall of the electric control platform 10, and the refrigerator 34 is embedded in the bottom inner wall of the electric control platform 10. The two flow pipes 35 are fixedly connected with the output end and the input end of the refrigerator 34 respectively. A flow port 36 is opened on the outer wall of one end of the flow pipe 35 away from the refrigerator 34, and the flow ports 36 at both ends are respectively connected with the inner walls at both ends of the condensation channel 14. It should be noted that the refrigerator 34 is an existing device on the market, and the present invention does not emphasize the introduction. The bottom outer wall of the outer rotating rod 15 is rotatably connected to the bottom inner wall of the condensation channel 14, and the outer wall of one end of the fan blade 16 is fixedly connected to the outer walls around the outer rotating rod 15.

[0037] In the present invention, the staff drives the electric control guide table 10 to slide on the outer wall of the guide rail 9 through the central control console 8. When the electric control guide table 10 is completely moved to the rear end, the upper die seat 6 will be vertically aligned with the lower die seat 13. At this time, the hydraulic rod 5 is driven to drive the upper die seat 6 to be pressed down and fully engaged with the lower die seat 13. The molten material is conducted into the mold through the feeder 4 and the feed telescopic tube 7 for die casting and shaping. Then, the refrigerator 34 discharges the condensed water into the condensation channel 14 through the flow pipe 35 at the output end, and then the condensed water is discharged from the flow pipe 35 at the input end and flows back into the refrigerator 34, thereby completing the condensation cycle. , the bottom outer wall of the lower die base 13 is cooled, so that the casting shrinks and takes shape when it is cooled, thereby breaking away from the adhesion to the inner wall of the lower die base 13. In the present invention, the flow of condensed water in the condensation channel 14 will impact the outer wall of the fan blade 16, thereby driving the fan blade 16 to rotate. In this way, the liquid flow characteristics of the condensed water are disturbed, so that the condensed water at the center of the water flow layer that fails to exchange heat with the outer wall of the lower die base 13 impacts the bottom outer wall of the lower die base 13 as the fan blade 16 rotates, thereby ensuring complete heat exchange of the water flow, accelerating the rapid cooling of the casting, and allowing the staff to more conveniently demold the casting quickly.

[0038] Embodiment 2, on the basis of embodiment 1, the outer wall of the fan blade 16 is fixedly mounted with a mounting seat 17 connected on the upper and lower sides, the top outer wall of the mounting seat 17 is provided with a through hole connected to the bottom outer wall, the inner wall of the through hole is movably connected with a connecting shaft 18, the bottom outer wall of the connecting shaft 18 is rotatably connected with a connecting magnet 19, the top outer wall of the guide rail 9 is fixedly inlaid with a plurality of limiting magnets 25, the plurality of limiting magnets 25 are distributed in an array, and the bottom outer wall of the condensation channel 14 separated by the connecting magnet 19 is electromagnetically connected to the limiting magnet 25.

[0039] In the present invention, after the casting is finalized, the upper mold base 6 moves up and disengages from the lower mold base 13, and the electric control guide platform 10 moves forward along the guide rail 9 to facilitate demolding by the staff. When the electric control guide platform 10 moves forward, it will pass through multiple limiting magnetic blocks 25 on the guide rail 9, and the connecting magnetic blocks 19 on the single-sided fan blades 16 will produce strong magnetic adsorption with the limiting magnetic blocks 25 on the path. At this time, the movement of the electric control guide platform 10 will synchronously cause the single fan blade 16 to rotate more than 120° around the outer rotating rod 15 as the axis. The array arrangement of multiple limiting magnetic blocks 25 can drive the continuous rotation of multiple groups of fan blades 16, thereby driving the curved rotation of the water flow, impacting the bottom outer wall of the lower mold base 13 for heat exchange, and facilitating the rapid demolding of the casting.

[0040] Embodiment three, on the basis of embodiment two, the top outer wall of the connecting shaft 18 is fixedly connected with a pressure plate 22, the outer walls around the connecting shaft 18 are sleeved with a return spring 23, the bottom outer wall of the return spring 23 is fixedly connected to the top outer wall of the mounting seat 17, the top outer wall of the return spring 23 is fixedly connected to the bottom outer wall of the pressure plate 22, the top outer wall of the pressure plate 22 is fixedly connected with a vibration block 24, the top outer wall of the vibration block 24 is movably fitted with the bottom outer wall of the lower mold seat 13, the connecting magnetic block 19 is provided with a mounting groove 20 connected at the upper and lower ends, the inner wall of the mounting groove 20 is rotatably connected with a roller 21, and the diameter of the roller 21 is slightly higher than the height of the mounting groove 20.

[0041] In the present invention, the distance between the mounting seat 17 and the pressure plate 22 is ensured by the elastic support of the connecting shaft 18. When the connecting magnetic block 19 and the limiting magnetic block 25 generate strong magnetic adsorption, the connecting magnetic block 19 will move downward to fit the bottom inner wall of the condensation channel 14, driving the pressure plate 22 to move downward to press the connecting shaft 18. When the fan blade 16 rotates more than 120°, the connecting magnetic block 19 will be out of the strong magnetic adsorption range with the limiting magnetic block 25. At this time, the compressed connecting shaft 18 will rebound instantly, driving the vibration block 24 to knock down. The bottom outer wall of the mold base 13 has been firmly attached to the inner wall of the lower mold base 13 because the casting in the lower mold base 13 has been cooled and fixed. At this time, the knocking vibration of the vibration block 24 is transmitted to the adhesion position, so that the casting can be completely demoulded by vibration, thereby facilitating the rapid demoulding of the casting, and through the rotation of the fan blades 16, a dot matrix range vibration is achieved, thereby further improving the demoulding effect of the casting, and the installation groove 20 is installed to facilitate the angle deflection of the connecting magnetic block 19 when it is attached to the inner wall of the condensation channel 14, thereby reducing friction resistance.

[0042] Embodiment 4, on the basis of embodiment 1, the outer rotating rod 15 is provided with an active hole connected at both ends, the inner wall of the active hole is provided with a fixed seat 29, the bottom outer wall of the fixed seat 29 is fixedly connected to the bottom inner wall of the condensation channel 14, the top outer wall of the fixed seat 29 is fixedly connected with the inner layer adjustment rod 30, a middle layer active rod 27 is provided between the outer wall of the active hole and the inner layer adjustment rod 30, the outer wall of the middle layer active rod 27 is movably connected to the inner wall of the active hole, a connecting groove 28 is provided on the bottom inner wall of the middle layer active rod 27, the inner wall of the connecting groove 28 is movably connected to the outer wall of the middle layer active rod 27, driving the top outer wall of the middle layer active rod 27 to be fixedly connected with a vibrating ring plate 26, the outer wall of the vibrating ring plate 26 is provided with an overflow groove 11 connected up and down, The outer walls on both sides of the middle movable rod 27 are fixedly connected with limiting blocks 39, and slots connected to the movable hole are provided on both sides of the top outer wall of the middle movable rod 27. The limiting blocks 39 are movably connected with the slots. Adjustment grooves 31 are provided on the outer walls around the inner adjusting rod 30, and the inner wall of the connecting groove 28 is fixedly connected with an adjusting block 32. The outer wall of the adjusting block 32 is slidably engaged with the inner wall of the adjusting groove 31. A return spring 2 33 is provided in the movable hole, and the inner wall of the return spring 2 33 is movably engaged with the outer wall of the middle movable rod 27. The outer wall of the middle movable rod 27 is fixedly connected with a limiting ring 37, and the top outer wall of the return spring 2 33 is fixedly connected to the bottom outer wall of the limiting ring 37, and the bottom outer wall of the return spring 2 33 is fixedly connected to the top outer wall of the fixing seat 29.

[0043] In the present invention, the movable clamping connection between the limiting plug block 39 and the slot is utilized, and the rotation of the fan blade 16 drives the vibration ring plate 26 and the middle movable rod 27 to rotate. At the same time, the inner layer adjustment rod 30 is in a fixed state, and the limiting of the adjustment block 32 causes the rotation of the middle layer movable rod 27 to drive the adjustment block 32 to slide on the inner wall of the adjustment groove 31. The adjustment block 32 rotates one circle on the top side of the adjustment groove 31 to the bottom side of the adjustment groove 31, and then returns to the top side through the rebound of the reset spring 2 33. In this cyclic motion, the rotation of the outer layer rotating rod 15 drives the vibration ring plate 26 to continuously knock on the bottom outer wall of the lower mold base 13, so that the casting can be completely demolded by vibration, thereby facilitating the rapid demolding of the casting.

[0044] Embodiment 5, on the basis of embodiment 4, the outer walls on both sides of the top of the electric control guide table 10 are fixedly connected with the slide rails 12, the outer walls on both sides of the lower mold base 13 are slidably connected with the outer walls of the slide rails 12, and the bottom outer wall of the lower mold base 13 and the condensation channel 14 are fixedly installed with a waterproof sealing rubber strip. The outer walls of the electric control guide table 10 on both sides of the lower mold base 13 are provided with elliptical adjustment rods 38, the outer walls of the elliptical adjustment rods 38 are in contact with the outer walls of the lower mold base 13, and the installation angles of the two elliptical adjustment rods 38 differ by 90°. The inner walls of the die-casting frame 1 are fixedly connected with limiting plug blocks 39 on both sides, the elliptical adjustment rod 38 is provided with a threaded groove connected at both ends, the inner wall of the threaded groove is threadedly connected with the outer wall of the elliptical adjustment rod 38, the outer wall of the electric control guide table 10 is provided with a through hole, and the outer wall of the elliptical adjustment rod 38 is movably connected with the inner wall of the through hole.

[0045] In the present invention, the movement of the electric control guide table 10 will drive the two elliptical adjustment rods 38 to move synchronously on the outer wall of the limit plug 39. Since the cross-section of the two elliptical adjustment rods 38 is elliptical and the installation angles differ by 90°, the rotation of the elliptical adjustment rods 38 will fit and squeeze the lower mold base 13, causing the lower mold base 13 to move slightly laterally on the top outer wall of the electric control guide table 10. The lateral movement is used to apply inertia to the casting, so that the casting can shake and loosen the adhesion position under the change of inertial pressure, thereby facilitating the rapid demolding of the casting. Through this lateral movement, the vibration range of the vibration block 24 and the vibration ring plate 26 in the condensation channel 14 is expanded, thereby further improving the demolding effect of the casting. Through this multi-directional movement pressure, even if the shape of the casting is complex, a better demolding effect can be produced.

[0046] Working principle and use process of the present invention: In the present invention, the staff drives the electric control guide table 10 to slide on the outer wall of the guide rail 9 through the central control console 8. When the electric control guide table 10 is completely moved to the rear end, the upper die seat 6 will be vertically aligned with the lower die seat 13. At this time, the hydraulic rod 5 is driven to drive the upper die seat 6 to be pressed down and fully engaged with the lower die seat 13. The molten material is conducted into the mold through the feeder 4 and the feed telescopic tube 7 for die casting and shaping. Subsequently, the refrigerator 34 discharges the condensed water into the condensation channel 14 through the flow pipe 35 at the output end, and then discharges the condensed water from the flow pipe 35 at the input end and flows back into the refrigerator 34, thereby completing the condensation cycle, cooling the bottom outer wall of the lower die seat 13, causing the casting to shrink and shape when it is cooled, thereby breaking away from the adhesion to the inner wall of the lower die seat 13. Attached, in the present invention, the flow of condensed water in the condensation channel 14 will impact the outer wall of the fan blade 16, thereby driving the fan blade 16 to rotate, and in this way disrupting the flow characteristics of the condensed water, so that the condensed water at the center of the water flow layer that fails to exchange heat with the outer wall of the lower mold base 13 impacts the bottom outer wall of the lower mold base 13 as the fan blade 16 rotates, thereby ensuring the complete heat exchange of the water flow, accelerating the rapid cooling of the casting, and allowing the staff to more conveniently demold the casting quickly. In the present invention, after the casting is finalized, the upper mold base 6 moves up and disengages from the lower mold base 13, and the electric control guide table 10 moves forward along the guide rail 9 to facilitate the staff to demold, and when the electric control guide table 10 moves forward, it will pass through multiple limiting magnetic blocks 25 on the guide rail 9, and the connecting magnetic block 19 on the single-side fan blade 16 will contact with the path The limiting magnetic block 25 on the diameter generates strong magnetic adsorption. At this time, the movement of the electric control guide table 10 will synchronously cause the single fan blade 16 to rotate more than 120° around the outer rotating rod 15 as the axis. The array arrangement of multiple limiting magnetic blocks 25 can drive the continuous rotation of multiple groups of fan blades 16, thereby driving the curved rotation of the water flow, impacting the bottom outer wall of the lower mold base 13 for heat exchange, and facilitating the rapid demoulding of the casting. In the present invention, the spacing between the mounting seat 17 and the pressure plate 22 is guaranteed by the elastic support of the connecting shaft 18. When the connecting magnetic block 19 and the limiting magnetic block 25 generate strong magnetic adsorption, the connecting magnetic block 19 will move downward to fit the bottom inner wall of the condensation channel 14, driving the pressure plate 22 to move downward to press the connecting shaft 18. When the fan blade 16 rotates within a range of 120° After the casting is put on, the connecting magnetic block 19 will be separated from the strong magnetic adsorption range of the limiting magnetic block 25. At this time, the compressed connecting shaft rod 18 will rebound instantly, driving the vibration block 24 to knock the bottom outer wall of the lower mold base 13. Since the casting in the lower mold base 13 has been cooled and fixed, the adhesion to the inner wall of the lower mold base 13 is already strong. At this time, the knocking vibration of the vibration block 24 is transmitted to the adhesion position, so that the casting can be completely demolded by vibration, thereby facilitating the rapid demolding of the casting, and through the rotation of the fan blade 16, a dot matrix range vibration is achieved, thereby further improving the demolding effect of the casting. By installing the installation groove 20, the angle deflection of the connecting magnetic block 19 when it is attached to the inner wall of the condensation channel 14 is facilitated, thereby reducing friction resistance. In the present invention, the movable clamping of the limiting plug block 39 and the slot is utilized.The rotation of the fan blades 16 drives the vibration ring plate 26 and the middle movable rod 27 to rotate. At the same time, the inner adjusting rod 30 is in a fixed state. The limit of the adjusting block 32 will cause the rotation of the middle movable rod 27 to drive the adjusting block 32 to slide on the inner wall of the adjusting groove 31. The adjusting block 32 rotates one circle on the top side of the adjusting groove 31 to the bottom side of the adjusting groove 31, and then returns to the top side through the rebound of the return spring 23. In this cyclic motion, the rotation of the outer rotating rod 15 drives the vibration ring plate 26 to continuously knock on the bottom outer wall of the lower mold base 13, so that the casting can be completely demolded by vibration, thereby facilitating the rapid demolding of the casting. In the present invention, the movement of the electric control guide table 10 will drive the two elliptical adjusting rods 38 to limit The outer wall of the plug block 39 moves synchronously with the thread. Since the cross-section of the two elliptical adjustment rods 38 is elliptical and the installation angles differ by 90°, the rotation of the elliptical adjustment rods 38 will fit and squeeze the lower die seat 13, causing the lower die seat 13 to move slightly laterally on the top outer wall of the electric control guide table 10. The lateral movement is used to apply inertia to the casting, so that the casting shakes and loosens the adhesion position under the change of inertial pressure, thereby facilitating the rapid demoulding of the casting. Through this lateral movement, the vibration range of the vibration block 24 and the vibration ring plate 26 in the condensation channel 14 is expanded, thereby further improving the demoulding effect of the casting. Through this multi-directional movement pressure, even if the shape of the casting is complex, it can produce a better demoulding effect.
