Description

Technical Field

[0001] The invention relates to the technical field of die-casting machines, and in particular to an automobile parts die-casting machine capable of reducing residual heat. Background Art

[0002] The die-casting machine is the most basic equipment for pressure casting production. Its working principle is to pour liquid or semi-liquid metal into the injection chamber of the die-casting machine, and then use the injection piston of the die-casting machine to press it into the pouring system and mold cavity of the die-casting mold at high speed and high pressure, and make it crystallize and solidify under a certain pressure to form, and then open the die-casting mold to obtain the casting.

[0003] Die-casting machines are widely used in the production of automotive parts. In the process of die-casting parts, in order to improve the cooling effect of the mold, coolant is often used to cool the mold before opening the mold, thereby reducing the residual heat of the mold and the die-casting when opening the mold, avoiding deformation of the die-casting, and improving the yield rate of the die-casting.

[0004] For example, a circulating die-casting machine with Chinese patent publication number CN113814370B includes a support table and a workbench on one side of the support table, a rotating table is installed inside the workbench, the rotating table is fixedly connected to a support plate, the side of the support plate away from the rotating table is fixedly connected to lower molds with equal spacing and circumferential distribution, the mold groove of the lower mold faces the axial direction of the support plate, the side of the support plate away from the rotating table is provided with an upper mold, the mold groove of the upper mold faces downward, the side of the upper mold away from the support plate is connected to a lifting platform, and the lifting platform is fixedly connected to the support table. This solution can cool the mold before opening the mold and preheat the mold before die-casting through the circulating coolant flow, making full use of the heat.

[0005] However, this solution cannot easily control the flow direction of the coolant. Since the liquid is affected by gravity, the higher the mold rises, the faster the coolant falls, which shortens the contact time between the mold and the coolant and prevents sufficient heat exchange. In addition, the mutual circulation between the coolants causes heat exchange between the coolants in contact with different molds, resulting in poor cooling and preheating effects, which needs to be improved. Summary of the invention

[0036] like Figures 1 to 11 As shown: A die-casting machine for reducing heat residue in automobile parts comprises a die-casting machine body 1, the die-casting machine body 1 comprises a base 10, a machine body 11 and a die-casting assembly 12, the bottom of the machine body 11 is fixedly connected to one end of the top of the base 10, the die-casting assembly 12 comprises an upper die 120, a turntable 121 and a plurality of lower die 122, the upper die 120 is vertically movably installed on the machine body 11, the turntable 121 is horizontally rotatably installed on the top of the base 10, a plurality of lower die 122 are circumferentially distributed on the turntable 121, the bottom of the lower die 122 passes through the turntable 121 and is fixedly connected thereto, the turntable 121 is rotated, and the lower die 122 is driven to rotate to the bottom of the upper die 120, then the upper die 120 is moved down and fits with the lower die 122 for die-casting, then the upper die 120 is reset, the turntable 121 continues to rotate, and the lower die 122 is counterclockwise exchanged, so that continuous die-casting operation can be performed, and it is also convenient to perform operations such as taking out parts and cleaning. It also includes a heat conversion component 2, a drive component 3 and a cleaning component 4. The heat conversion component 2 includes an operating table 20, a chassis 21 and a reverse linkage mechanism 22. The bottom of the operating table 20 is fixedly connected to the top of the base 10, the bottom of the chassis 21 passes through the operating table 20 and is rotatably connected thereto, an annular groove 210 and a plurality of water tanks 211 are provided on the top of the chassis 21, the annular groove 210 is communicated with the water tank 211, and the water tank 211 is located at the bottom of the annular groove 210. When die-casting, the upper mold 120 squeezes the lower mold 122 and pushes the turntable 121 downward, so that the turntable 121 and the chassis 21 fit each other, and the bottom of the lower mold 122 is immersed in the water tank 211. The lower mold 122 is quickly cooled by the coolant in the water tank 211, so that the die-casting is quickly finalized, which can not only improve the die-casting efficiency, but also prevent the die-casting from sticking when the mold is separated. At the same time, the coolant is heated, and then while the turntable 121 rotates counterclockwise, the chassis 21 rotates clockwise following the turntable 121 through the reverse linkage mechanism 22, so that the lower mold 122 with the die-casting part leaves the die-casting station, and the heated coolant leaves the die-casting station in the opposite direction, which can preheat the lower mold 122 to be die-casted, improve the die-casting effect of the liquid metal, and then the cooled coolant continues to rotate and returns to the die-casting station from the other side to form a cycle. In this process, the lower mold 122 can be further cooled to prevent adhesion and deformation when taking out the parts. The coolant adsorbed on the bottom of the lower mold 122 is collected by the annular groove 210 and flows back into the water tank 211 to prevent splashing. The reverse linkage mechanism 22 is installed on the chassis 21. The reverse linkage mechanism 22 is used to drive the turntable 121 and the chassis 21 to rotate in the opposite direction at the same time. The driving component 3 and the cleaning component 4 are both installed on the base 10. The driving component 3 is used to drive the heat conversion component 2 to work, and the cleaning component 4 is used to clean the lower mold 122. When the bottom of the turntable 121 is in contact with the top of the chassis 21, the bottom of the lower mold 122 is located in the water tank 211. At this time, the lower mold 122 exchanges heat with the coolant in the water tank 211.When the rotating disk 121 is separated from the bottom plate 21, the lower mold 122 is separated from the water tank 211. At this time, the lower mold 122 can rotate along the annular groove 210 to change the working position.

[0037] like Figures 1 to 8 As shown: The reverse linkage mechanism 22 includes a transmission shaft 220, an internal gear 221, a fixed gear 222, a rotating shaft 223 and a gear ring 224. The top of the transmission shaft 220 is coaxially connected to the bottom of the turntable 121, the internal gear 221 is coaxially connected to the periphery of the transmission shaft 220, the fixed gear 222 is rotatably connected to the periphery of the rotating shaft 223, one side of the fixed gear 222 is meshed with the internal gear 221, a through cavity 212 is opened at the bottom of the chassis 21, the bottom of the rotating shaft 223 passes through the cavity 212 and is fixedly connected to the top of the base 10, the gear ring 224 is fixedly connected to the inner wall of the cavity 212, and the gear ring 224 is meshed with the other side of the fixed gear 222. When the transmission shaft 220 rotates, it drives the internal gear 221 to rotate, and through the meshing transmission between it and the fixed gear 222, the fixed gear 222 rotates around the rotating shaft 223, and through the meshing transmission between the fixed gear 222 and the gear ring 224, the gear ring 224 drives the chassis 21 to rotate horizontally on the operating table 20, and the internal gear 221 and the gear ring 224 rotate coaxially and in opposite directions, so that the chassis 21 and the turntable 121 rotate in opposite directions, thereby driving the lower mold 122 and the water tank 211 to move in opposite directions.

[0038] like Figures 1 to 6 As shown: The heat conversion assembly 2 also includes a plurality of stirring mechanisms 23, which are installed in the water tank 211. The stirring mechanism 23 includes a fan blade 230 and a spur gear 231. The bottom of the fan blade 230 passes through the bottom wall of the water tank 211 and is rotatably connected thereto. The top of the spur gear 231 is coaxially connected to the bottom of the fan blade 230. The spur gear 231 is located at the top of the fixed gear 222, and the spur gear 231 is meshed with the inner gear 221. When the inner gear 221 rotates, the chassis 21 drives the plurality of fan blades 230 and the spur gear 231 to rotate around the transmission shaft 220. Through the meshing transmission between the inner gear 221 and the spur gear 231, the spur gear 231 also rotates in the opposite direction when rotating around the transmission shaft 220, thereby driving the fan blade 230 to rotate and stir the coolant to make it flow, thereby improving the contact heat conduction efficiency between the coolant and the lower mold 122.

[0039] like Figures 1 to 7 As shown: The heat conversion assembly 2 further includes a limit rod 24 and a return spring 25. The limit rod 24 passes through the top of the transmission rod and is fixedly connected thereto. A circular groove 1210 is provided at the bottom of the turntable 121.

One end of the return spring 25 is fixedly connected to the top of the transmission rod, and the other end of the return spring 25 is fixedly connected to the top wall of the circular groove 1210. When the upper mold 120 squeezes the lower mold 122, the turntable 121 is pushed down and squeezes the return spring 25 to compress it. The limit rod 24 slides upward in the circular groove 1210. After the mold is separated, the turntable 121 moves up under the push of the rebound force of the return spring 25. Then, when the transmission shaft 220 rotates, the limit rod 24 is engaged with the inner wall of the circular groove 1210 to drive the turntable 121 to rotate.

[0040] like Figures 1 to 8 As shown: The heat conversion assembly 2 also includes a plurality of anti-backflow mechanisms 26, which are distributed circumferentially on the turntable 121. The anti-backflow mechanisms 26 are located between the two lower molds 122. The anti-backflow mechanisms 26 include a baffle 260 and a pair of tension springs 261. The baffle 260 passes through the turntable 121 and is slidably connected thereto. The bottom of the baffle 260 is slidably connected to the annular groove 210. The two tension springs 261 are respectively located on both sides of the baffle 260. One end of the tension spring 261 is fixedly connected to the top of the baffle 260, and the other end of the tension spring 261 is fixedly connected to the top of the turntable 121. When the turntable 121 is in contact with the chassis 21, the bottom of the baffle 260 is supported by the annular groove 210 and the tension spring 261 is stretched. When the turntable 121 moves up and separates from the chassis 21, the tension spring 261 rebounds, so that the bottom of the baffle 260 is always in contact with the inner wall of the annular groove 210. When the turntable 121 rotates, the baffle 260 rotates with the turntable 121, and the rotation direction is opposite to that of the chassis 21, thereby preventing the coolant brought out by the lower mold 122 from flowing into the next workstation and causing heat loss.

The bottom of the other end of the cleaning roller 43 fits with the top of the lower mold 122. One end of the motor 44 is fixedly connected to the support seat 42. The output shaft of the motor 44 passes through the support seat 42 and is coaxially connected to the cleaning roller 43. The motor 44 is powered on and its output shaft drives the cleaning roller 43 to rotate. At the same time, the tension spring 41 is in a stretched state. The rebound force of the tension spring 41 drives the support rod 40 to slide down, so that the bottom of the cleaning roller 43 fits with the lower mold 122. Even if the lower mold 122 moves down during mold closing, the fit can be maintained, thereby cleaning the lower mold 122. The rotation direction of the cleaning roller 43 is opposite to that of the lower mold 122, further improving the cleaning effect.

[0042] like Figures 1 to 9 As shown: The cleaning assembly 4 further includes a plurality of brackets 45, which are arranged circumferentially on the turntable 121, and the brackets 45 are located on the side of the baffle 260 away from the center of the turntable 121, and the bottom of the brackets 45 is fixedly connected to the top of the turntable 121. When the turntable 121 rotates, the brackets 45 rotate with the turntable 121, and when the brackets 45 contact the cleaning roller 43, as the rotation continues, the cleaning roller 43 is pushed up by the brackets 45, and the tension spring 41 is further stretched, so that the cleaning roller 43 does not contact the baffle 260 to prevent wear.
