[0002] Casting, also known as (static) casting, is the process of injecting the prepared casting raw materials into a mold to solidify it, and obtaining a product similar to the mold cavity. The raw materials for casting can be monomers, slurries that have undergone preliminary polymerization or polycondensation, or solutions of polymers and monomers. Polymerization or polycondensation reactions usually occur during the solidification process. In recent years, some new casting methods have emerged based on traditional casting, including embedded casting, centrifugal casting, cast casting, slush molding, rotational molding, etc.

[0003] In the existing aluminum liquid casting process, either a certain amount of aluminum liquid is taken from the furnace by a clamp container and poured into the mold, or a certain amount of aluminum liquid is taken from the furnace by a robot and automatically poured into the mold. No matter which of the above methods is used, it is necessary to hold the container to take a certain amount of aluminum liquid from the furnace and then move it to the mold to complete the pouring. When the container is filled with aluminum liquid and moved to the pouring position, it is inevitable that some of the aluminum liquid will splash or drip onto the ground and the assembly line processing table.

DETAILED DESCRIPTION

[0035] use Figure 1-Figure 3 The automatic molten aluminum casting machine described in the present invention is described as follows.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.

[0037] The example of the present invention provides a method for improving the existing aluminum liquid casting process, in which either a clamp is used to hold a container manually to take a certain amount of aluminum liquid from the furnace and pour it into a mold, or a robot is used to hold a container to take a certain amount of aluminum liquid from the furnace and automatically pour it into the mold. No matter which of the above methods is used, it is necessary to hold the container to take a certain amount of aluminum liquid from the furnace and then move it to the mold to complete the pouring. When the container is filled with aluminum liquid and moved to the pouring position, it is inevitable that part of the aluminum liquid will splash or drip onto the ground and the assembly line processing table. The dripping or splashing of the hot aluminum liquid will not only pose a huge threat to the safety of personnel, but may also damage other production equipment on site, causing waste of resources and increasing the burden of personnel in the subsequent cleaning.

[0038] The technical solution in the embodiment of the present invention is to solve the above-mentioned technical problems, and the overall idea is as follows: a container containing molten aluminum is clamped by setting a clamping assembly, and then the clamping assembly is driven to move upward by the lifting assembly. The clamping assembly moves to a certain height and pours the molten aluminum inside the container directly into the feed trough, thereby reducing the process of manual or robotic clamping of the container to contain the molten aluminum and moving it to the pouring position, thereby preventing the molten aluminum from splashing or dripping onto the ground and the assembly line processing table.

[0039] The present invention provides an automatic aluminum casting machine, comprising a cover body 1, a mold cover body 2 arranged below the cover body 1 and a base 3 at the bottom, and further comprising:

[0040] A material trough 4, which is annularly connected to the outside of the mold cover 2 and communicates with the inside of the mold cover 2;

[0041] A housing 5, wherein the housing 5 is disposed below the mold cover 2 and connected to the base 3;

[0042] A clamping assembly, which is arranged on both sides of the housing 5 and is used to clamp and fix the holding furnace containing molten aluminum;

[0043] Lifting components, which are arranged on both sides of the housing 5 and connected to the clamping components, and are used to drive the clamping components to rise or rotate;

[0044] When it is necessary to cast molten aluminum, the operator pushes the holding furnace containing molten aluminum directly to the side of the casting machine using a trolley. Under the control of the electrical system, the motor in the lifting assembly is started. The lifting assembly changes the height from the bottom surface upward or downward under the drive of the motor, and then, with the assistance of the electronic positioning system, the clamping assembly connected to the front end of the lifting assembly is adjusted from top to bottom to a suitable position from the clamping point of the holding furnace. After that, the motor in the clamping assembly is powered on and started, so that the clamping assembly can complete the process from opening and releasing to contracting and clamping. With the help of the lifting assembly, the clamping assembly is sleeved on the outer wall of the holding furnace from top to bottom, and as the clamping assembly is tightened, the holding furnace is clamped. Then, the lifting assembly uses the clamping assembly to lift the holding furnace to a position where the furnace mouth is slightly higher than the material trough 4, and then stops. At this time, the clamping assembly is tilted at a certain angle under the action of the flip motor in the lifting assembly, so that the aluminum liquid in the holding furnace can be poured out from the furnace mouth and enter the material trough 4, thereby completing the automatic pouring process of the aluminum liquid;

[0045] Compared with the prior art, in the process of molten aluminum casting, either a clamp is used to hold a container manually to take a certain amount of molten aluminum from the furnace and pour it into the mold, or a robot is used to hold a container to take a certain amount of molten aluminum from the furnace and automatically pour it into the mold. No matter which of the above methods is used, it is necessary to hold the container to take a certain amount of molten aluminum from the furnace and then move it to the mold to complete the pouring. When the container is filled with molten aluminum and moved to the pouring position, it is inevitable that some of the molten aluminum will splash or drip onto the ground and the assembly line processing table. The dripping or splashing of hot molten aluminum will not only pose a huge threat to personnel safety, but may also damage other production equipment on site, causing waste of resources and increasing the burden of personnel in the later cleaning.

[0046] The present invention realizes clamping and dumping of the holding furnace containing molten aluminum by arranging a clamping component, and controls the longitudinal movement of the holding furnace by a lifting component, thereby realizing the position adjustment of the holding furnace to complete the automatic pouring process of the molten aluminum;

[0047] Firstly, the present invention only requires manual labor to move the holding furnace containing aluminum liquid into the range of the lifting assembly, and then the clamping assembly and the lifting assembly, under the action of the electrical control system, complete the automatic pouring of aluminum liquid, thereby reducing manual labor, improving production efficiency, and reducing safety risks;

[0048] Secondly, the present invention can not only ensure the longitudinal displacement of the lifting assembly, but also realize that the lifting assembly can rotate with the center of the base 3 as the center of the circle. Therefore, when the casting is large in volume and irregular in shape, the rotating lifting assembly can drive the insulation furnace to perform multi-directional annular pouring on the casting in the mold cover 2 along the annular material trough 4 fixedly installed on the outside of the mold cover 2 and connected to the inside of the mold cover 2. While being able to adapt to the pouring of castings with large volume and irregular shape, it also avoids the poor fluidity of aluminum liquid and uneven pouring in a single direction.

[0049] Thirdly, the present invention directly connects the holding furnace containing molten aluminum with the pouring machine through the clamping assembly and the lifting assembly, thereby eliminating the need to use a container to hold molten aluminum little by little from the furnace outside the pouring machine and move it to the pouring point in the traditional molten aluminum pouring process, thereby avoiding the splashing and dripping of molten aluminum that may occur during the movement, improving the utilization rate of molten aluminum, reducing safety risks, and reducing the time required for manual cleaning of molten aluminum residue on the bottom surface in the later stage;

[0050] As a specific embodiment of the present invention, the lifting assembly includes:

[0051] A lifting motor 14, wherein the lifting motor 14 is disposed inside mounting grooves provided on both sides of the housing 5;

[0052] A lifting screw rod 12, wherein the lifting screw rod 12 is connected to an output shaft of a lifting motor 14;

[0053] The lifting slider 10 is threadedly engaged with the lifting screw rod 12 .

[0054] The lifting assembly is installed in the mounting grooves on both sides of the housing 5, and the position of the clamping assembly relative to the holding furnace can be adjusted by adjusting its own height;

[0055] When the holding furnace containing aluminum liquid is manually pushed to the travel area of ​​the lifting component, with the assistance of the electrical control system and the electronic positioning system;

[0056] When the lifting motor 14 fixedly installed at the bottom of the mounting grooves on both sides of the housing 5 is energized, the output shaft of the lifting motor 14 rotates, and the rotational force is transmitted to the lifting screw rod 12. One end of the lifting screw rod 12 is fixedly connected to the output shaft of the lifting motor 14, and the other end is rotatably connected to the top of the mounting groove. At this time, the lifting screw rod 12 rotates together with the output shaft of the lifting motor 14. The rotating lifting screw rod 12 drives the lifting slider 10 threadedly engaged with the lifting screw rod 12 to rise through the threaded engagement transmission. Since the lifting slider 10 and the mounting groove are both rectangular, under this shape limitation, the lifting slider 10 will only move longitudinally upward in the mounting groove. During the upward movement of the lifting slider 10, the clamping component fixedly connected to one side of the lifting slider 10 will be driven to move upward;

[0057] When the lifting motor 14 fixedly installed at the bottom of the mounting grooves on both sides of the housing 5 is energized, the output shaft of the lifting motor 14 will be reversed, and the rotational force will be transmitted to the lifting screw rod 12. One end of the lifting screw rod 12 is fixedly connected to the output shaft of the lifting motor 14, and the other end is rotatably connected to the top of the mounting groove. At this time, the lifting screw rod 12 will rotate together with the output shaft of the lifting motor 14. The rotating lifting screw rod 12 will drive the lifting slider 10 threadedly engaged with the lifting screw rod 12 to descend through the threaded engagement transmission. Since the lifting slider 10 and the mounting groove are both rectangular, under this shape limitation, the lifting slider 10 will only move longitudinally downward in the mounting groove. During the downward movement of the lifting slider 10, the clamping assembly fixedly connected to one side of the lifting slider 10 will be driven to move downward;

[0058] Thus, the longitudinal movement of the lifting assembly is completed by the forward and reverse rotation of the lifting motor 14 in the lifting assembly, thereby realizing the height of the clamping assembly relative to the ground and the insulation furnace.

[0059] As a specific embodiment of the present invention, the clamping assembly includes:

[0060] A fixing rod 15, one end of which is connected to the lifting slider 10;

[0061] A clamping arm 16, wherein the clamping arm 16 is connected to the fixing rod 15;

[0062] A second motor 7, wherein the second motor 7 is fixed to the front end of the fixing rod 15;

[0063] A screw rod 17, the screw rod 17 passes through the clamping arms 16 on both sides and is connected to the second motor 7;

[0064] The third motor 8 is arranged at the front end of the fixing rod 15 .

[0065] Under the control of the electrical system and the positioning system, the lifting device adjusts the entire clamping assembly to the top of the insulation furnace mouth through the fixed rod 15, one end of which is fixedly connected to the lifting slider 10. At this time, the No. 2 motor 7 fixedly installed at the front end of the fixed rod 15 rotates, and the rotating No. 2 motor 7 drives the screw rod 17 that runs through the clamp arms 16 on both sides and is fixedly connected to the output shaft of the No. 2 motor 7 at one end to rotate through the output shaft. The two clamp arms 16 are slidably connected to one end of the L-shaped fixed rod 15, and the screw rod 17 is threadedly engaged with the two clamp arms 16 respectively. In addition, the threads in the two clamp arms 16 rotate in opposite directions. Therefore, when the No. 2 motor 7 reverses, the screw rod 17 drives the two clamp arms 16 to move relatively away horizontally along one end of the L-shaped fixed rod 15 through the threaded engagement transmission, that is, the opening of the clamp arms 16 is completed;

[0066] The inner diameter of the opened clamping arm 16 is larger than the diameter of the holding furnace, so under the control of the electrical system, the lifting assembly moves the clamping assembly downward just above the holding furnace until the semi-enclosed space formed by the opened clamping arm 16 surrounds the clamping area of ​​the holding furnace;

[0067] At this time, the second motor 7 rotates forward, and the screw rod 17 drives the two clamping arms 16 to move relatively close horizontally along one end of the L-shaped fixed rod 15 through threaded engagement transmission, until the clamping arms 16 contact the insulation furnace, and continue to apply force, that is, the clamping arms 16 complete the clamping of the insulation furnace;

[0068] Then, the lifting assembly drives the clamping assembly that clamps the holding furnace to rise until the furnace mouth of the holding furnace is higher than the upper end of the material trough 4 and stops;

[0069] The third motor 8 is located on one side of the fixed rod 15, and the fixed rod 15 is divided into a left end close to the casting machine body and a right end close to the clamp arm 16. The body of the third motor 3 is fixedly connected to the left end of the fixed rod 15, and the output shaft of the third motor 3 is fixedly connected to the right end of the fixed rod 15. The fixed rod 15 on the other side is hinged at the position corresponding to the third motor 8, that is, when the third motor 8 rotates forward, the right end of the fixed rod 15 can be rotated upward with the third motor 8 as the axis. The turned-up insulation furnace will pour the molten aluminum in the furnace into the annular material trough 4 through the furnace mouth, thereby completing the automatic pouring of the molten aluminum. When the pouring is completed, the No. 3 motor 8 reverses and the right end of the fixing rod 15 can be turned back clockwise with the No. 3 motor 8 as the axis, thereby driving the holding furnace suspended in the air clamped by the clamp arm 16 to turn back to a horizontal state synchronously, thereby stopping the pouring of the molten aluminum.

[0070] As a specific implementation of the present invention, a No. 4 motor 9 is provided inside the base 3 , a No. 2 gear 11 is connected to the output shaft of the No. 4 motor 9 , and the No. 2 gear 11 meshes with a No. 2 tooth groove 13 provided inside the housing 5 .

[0071] During the pouring of molten aluminum, the No. 4 motor 9 fixedly connected to the inside of the base 3 works, driving the No. 2 gear 11 fixedly connected to the output shaft of the No. 4 motor 9 to rotate, and the No. 2 gear 11 meshes with the No. 2 tooth groove 13 provided in the shell 5, and the No. 2 gear 11 drives the shell 5 connected between the mold cover 2 and the base 3 to rotate, and the rotation of the shell 5 can drive the lifting assembly to rotate, and the rotation of the lifting assembly drives the clamping assembly to rotate, and finally the rotating lifting assembly can drive the insulation furnace along the annular material trough 4 fixedly installed on the outside of the mold cover 2 and connected to the inside of the mold cover 2 to perform multi-directional annular pouring on the casting in the mold cover 2, while being able to adapt to the pouring of castings with large volume and irregular shape, it also avoids the poor fluidity of the aluminum liquid and the uneven pouring in a single direction;

[0072] As a specific implementation of the present invention, a plurality of feed ports 18 are evenly arranged in the material trough 4 .

[0073] When the mold is large or irregular in shape, by evenly opening a plurality of feed ports 18 on the mold cover 2, the molten aluminum can enter the mold from the plurality of feed ports 18 during the process of the clamping assembly rotating and pouring the molten aluminum, so that the molten aluminum entering the mold can be diffused more evenly, reducing the possibility of increasing defective products due to uneven diffusion and ensuring the success rate of the casting process.

[0074] As a specific implementation of the present invention, a shift block 19 is connected to the inner wall of the shell 5 , and an elastic ruler 20 is provided below the mold cover 2 .

[0075] During the rotation of the shell 5, the rotation of the shell 5 drives the shift block 19 fixedly connected to the inside of the shell 5 to rotate. The rotation of the shift block 19 drives the elastic ruler 20 fixedly connected to the bottom of the mold cover 2, so that the elastic ruler 20 swings back and forth. The back and forth swing of the elastic ruler 20 can drive the mold cover 2 to shake slightly. The shaking of the mold cover 2 can accelerate the diffusion speed of the molten aluminum during the aluminum casting process, and can also make the aluminum water diffuse more evenly.

[0076] As a specific implementation of the present invention, the elastic ruler 20 is made of spring steel.

[0077] Since spring steel has good elasticity, the material of the elastic ruler 20 is made of spring steel. When the shift block 19 shifts the elastic ruler 20, the movement amplitude of the elastic ruler 20 can be increased, thereby increasing the shaking of the mold cover 2, further improving the diffusion speed of the aluminum water and the uniformity of the diffusion process.

[0078] As a specific embodiment of the present invention, a baffle 21 connected to the mold cover 2 is provided at the feed port 18 .

[0079] During the process of the clamping assembly pouring the molten aluminum into the feed trough 4, the baffle 21 arranged at the feed port 18 and slidably connected to the mold cover 2 always blocks the feed port 18. When the molten aluminum in the trough 4 reaches a certain amount, the operator pushes the baffle 21 upward to open the feed port 18, and the molten aluminum enters the mold from the feed port 18. The speed of the molten aluminum entering multiple feed ports 18 can be made the same, thereby further ensuring the uniformity of the mold casting process and reducing the occurrence of defective products.

[0080] As a specific implementation of the present invention, the inner wall of the material trough 4 forms a certain slope.

[0081] By setting the bottom surface inside the trough 4 to gradually rise from close to the mold cover 2 to away from the mold cover 2, during the molten aluminum casting process, the molten aluminum can enter the feed port 18 along this slope, reducing the residual amount of molten aluminum inside the trough 4 and improving the utilization rate of the molten aluminum.

[0082] As a specific implementation of the present invention, the diameter of the feed port 18 gradually decreases from the outside of the mold cover body 2 to the inside of the mold cover body 2.

[0083] By gradually reducing the diameter of the feed port 18 from the outside of the mold cover 2 to the inside of the mold cover 2, the pressure inside the feed port 18 gradually increases from the outside to the inside, thereby increasing the flow rate of molten aluminum flowing into the mold cover 2, accelerating the casting speed, and improving work efficiency.

[0084] Working principle: When the holding furnace containing aluminum liquid is manually pushed to the travel area of ​​the lifting component, with the assistance of the electrical control system and the electronic positioning system;

[0085] When the lifting motor 14 fixedly installed at the bottom of the mounting grooves on both sides of the housing 5 is energized, the output shaft of the lifting motor 14 rotates, and the rotational force is transmitted to the lifting screw rod 12. One end of the lifting screw rod 12 is fixedly connected to the output shaft of the lifting motor 14, and the other end is rotatably connected to the top of the mounting groove. At this time, the lifting screw rod 12 rotates together with the output shaft of the lifting motor 14. The rotating lifting screw rod 12 drives the lifting slider 10 threadedly engaged with the lifting screw rod 12 to rise through the threaded engagement transmission. Since the lifting slider 10 and the mounting groove are both rectangular, under this shape limitation, the lifting slider 10 will only move longitudinally upward in the mounting groove. During the upward movement of the lifting slider 10, the clamping component fixedly connected to one side of the lifting slider 10 will be driven to move upward;

[0086] When the lifting motor 14 fixedly installed at the bottom of the mounting grooves on both sides of the housing 5 is energized, the output shaft of the lifting motor 14 will be reversed, and the rotational force will be transmitted to the lifting screw rod 12. One end of the lifting screw rod 12 is fixedly connected to the output shaft of the lifting motor 14, and the other end is rotatably connected to the top of the mounting groove. At this time, the lifting screw rod 12 will rotate together with the output shaft of the lifting motor 14. The rotating lifting screw rod 12 will drive the lifting slider 10 threadedly engaged with the lifting screw rod 12 to descend through the threaded engagement transmission. Since the lifting slider 10 and the mounting groove are both rectangular, under this shape limitation, the lifting slider 10 will only move longitudinally downward in the mounting groove. During the downward movement of the lifting slider 10, the clamping assembly fixedly connected to one side of the lifting slider 10 will be driven to move downward;

[0087] Thus, the longitudinal movement of the lifting assembly is completed by the forward and reverse rotation of the lifting motor 14 in the lifting assembly, thereby realizing the height of the clamping assembly relative to the ground and the holding furnace;

[0088] Under the control of the electrical system and the positioning system, the lifting device adjusts the entire clamping assembly to the top of the insulation furnace mouth through the fixed rod 15, one end of which is fixedly connected to the lifting slider 10. At this time, the No. 2 motor 7 fixedly installed at the front end of the fixed rod 15 rotates, and the rotating No. 2 motor 7 drives the screw rod 17 that runs through the clamp arms 16 on both sides and is fixedly connected to the output shaft of the No. 2 motor 7 at one end to rotate through the output shaft. The two clamp arms 16 are slidably connected to one end of the L-shaped fixed rod 15, and the screw rod 17 is threadedly engaged with the two clamp arms 16 respectively. In addition, the threads in the two clamp arms 16 rotate in opposite directions. Therefore, when the No. 2 motor 7 reverses, the screw rod 17 drives the two clamp arms 16 to move relatively away horizontally along one end of the L-shaped fixed rod 15 through the threaded engagement transmission, that is, the opening of the clamp arms 16 is completed;

[0089] The inner diameter of the opened clamping arm 16 is larger than the diameter of the holding furnace, so under the control of the electrical system, the lifting assembly moves the clamping assembly downward just above the holding furnace until the semi-enclosed space formed by the opened clamping arm 16 surrounds the clamping area of ​​the holding furnace;

[0090] At this time, the second motor 7 rotates forward, and the screw rod 17 drives the two clamping arms 16 to move relatively close horizontally along one end of the L-shaped fixed rod 15 through threaded engagement transmission, until the clamping arms 16 contact the insulation furnace, and continue to apply force, that is, the clamping arms 16 complete the clamping of the insulation furnace;

[0091] Then, the lifting assembly drives the clamping assembly that clamps the holding furnace to rise until the furnace mouth of the holding furnace is higher than the upper end of the material trough 4 and stops;

[0092] The third motor 8 is located on one side of the fixed rod 15, and the fixed rod 15 is divided into a left end close to the casting machine body and a right end close to the clamp arm 16. The body of the third motor 3 is fixedly connected to the left end of the fixed rod 15, and the output shaft of the third motor 3 is fixedly connected to the right end of the fixed rod 15. The fixed rod 15 on the other side is hinged at the position corresponding to the third motor 8, that is, when the third motor 8 rotates forward, the right end of the fixed rod 15 can be rotated upward with the third motor 8 as the axis. The turned-up insulation furnace will pour the molten aluminum in the furnace into the annular material trough 4 through the furnace mouth, thereby completing the automatic pouring of the molten aluminum. When the pouring is completed, the No. 3 motor 8 reverses and the right end of the fixing rod 15 can be turned back clockwise with the No. 3 motor 8 as the axis, thereby driving the holding furnace suspended in the air clamped by the clamp arm 16 to turn back to a horizontal state synchronously, thereby stopping the pouring of the molten aluminum.
