Description

Technical Field

[0001] The invention belongs to the technical field of die casting, and in particular relates to an automatic feeding die casting mould. Background Art

[0002] With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, die-casting technology has achieved extremely rapid development. The high-tech of die-casting has continuously put forward higher and newer requirements for die-casting machines. Die-casting production not only dominates non-ferrous alloy casting, but has also become an important part of modern industry.

[0003] Traditional die-casting machines often require manual loading when working. Due to the high temperature of the die-casting machine and the poor working environment, the high temperature can easily affect the operator's work efficiency, and there is a risk of scalding when loading, which has low safety. In the prior art, some die-casting machines use conveyor belts to automatically load solid melts. However, due to the irregular shape of the solid melt, it is easy to accumulate and clog at the outlet, and the solid melt is easy to roll and slip on the surface of the conveyor belt during transportation, and thus the stable feeding of the solid melt cannot be guaranteed. When the feed amount of the solid melt is unstable, it is easy to cause changes in the furnace temperature in the melting furnace, thereby reducing the die-casting work efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic feeding die-casting mold with stable feeding amount and high efficiency in view of the problems raised in the above background technology.

[0006] The feeding mechanism includes a first roller and a second roller rotatably connected to the inner wall of the conveying box, a conveyor belt I is sleeved on the outer side walls of the first roller and the second roller, a third roller and a fourth roller are arranged directly below the first roller and the second roller, the third roller and the fourth roller are both rotatably connected to the inner wall of the conveying box, and a conveyor belt II is sleeved on the outer side walls of the third roller and the fourth roller, protrusion bags are equidistantly arranged on the outer side walls of the conveyor belt I and the conveyor belt II, and the protrusion bags are filled with electrorheological fluid, a positive electrode plate is arranged between the first roller and the second roller, a negative electrode plate is arranged between the third roller and the fourth roller, and the positive electrode plate and the negative electrode plate are respectively connected to the positive and negative electrodes of an external power supply through a power connection component.

[0007] Furthermore, the feeding mechanism also includes a motor installed on the side wall of the conveying box, the output shaft of the motor is connected to a driving gear through a coupling, the driving gear is fixedly connected to the first roller, the third roller is connected to a driven gear, and the driving gear is meshed with the driven gear.

[0008] Furthermore, the power connection component includes a turntable fixedly connected to the fourth roller, a plurality of centrifugal cylinders are equidistantly fixed on the peripheral side wall of the turntable, a centrifugal ball is slidably arranged in the centrifugal cylinder, and the centrifugal ball is movably connected to the inner wall of the centrifugal cylinder through an elastic rope.

[0009] Furthermore, the power connection assembly also includes a fixed block fixedly connected to the outer side wall of the conveying box, the fixed block is connected to a movable block via a reset spring, two guide rods are fixedly connected to the bottom of the movable block, the lower ends of the guide rods are inserted through the fixed block, and conductive heads are fixedly connected to the side walls of the fixed block and the movable block that are close to each other, and the conductive heads are connected to an external power supply. When the two conductive heads are in contact, the positive plate and the negative plate are energized.

[0010] Furthermore, the lower surface of the movable block is an arc-shaped surface, and the center of the arc-shaped surface falls on the center of the turntable, so that the centrifugal ball can slide on the arc-shaped surface of the movable block when rotating.

[0011] Furthermore, rotating shafts are fixedly provided on both sides of the feed pipe, and the rotating shafts are rotatably connected to the side walls at the bottom opening of the discharge channel through bearings. One end of the feed pipe extends into the discharge channel and is connected to the bottom of the discharge channel through a vibration spring, and the other end of the feed pipe extends to the input ends of conveyor belts I and II.

[0015] 1. By setting up a material discharge box, a material discharge channel and a material feeding pipe, an appropriate amount of solid melt can be stored in the material discharge box at one time. When in use, the solid melt enters the material feeding pipe from the material discharge channel and rolls down to the space between conveyor belts I and II through the material feeding pipe. There is no need for manual approach to material loading, which reduces labor intensity and improves safety.

[0016] In addition, the feed pipe can reciprocate and vibrate during feeding. On the one hand, it can continuously push the solid melt at the bottom of the discharge channel to move, preventing the solid melt from accumulating and clogging at the bottom outlet end of the discharge channel. On the other hand, it can cause the solid melt in the feed pipe to roll down quickly, further avoiding blockage problems and improving feeding efficiency.

[0017] 2. By setting up a feeding mechanism, conveyor belt I and conveyor belt II rotate synchronously in opposite directions, and the solid melt between the two is stably transported. The electrorheological fluid in the protruding capsules located at the front end of conveyor belts I and II is liquid, and the protruding capsules can be deformed to wrap the solid melt. As the conveyor belts run, when the solid melt wrapped in the protruding capsules moves to the positive plate and the negative plate, it is affected by the electric field between the positive plate and the negative plate, and the electrorheological fluid changes from liquid to solid under the action of the electric field, so that the protruding capsules are shaped and the solid melt is fixed, thereby making the transportation of the solid melt more stable, preventing the solid melt from rolling and accumulating on the conveyor belt, and facilitating the staff to control the feed amount, so that the feed amount is stable and avoids causing changes in the furnace temperature in the melting furnace.

[0018] 3. By setting up the power connection components, the positive plate and the negative plate are powered on when the conveyor belts I and II are running, and the power is automatically cut off after the feeding stops. There is no need for manual control of the on and off, which reduces labor costs and saves energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] like Figure 1-5 As shown, an automatic feeding die-casting mold includes a workbench 1, a die-casting box 2 is fixedly arranged on the workbench 1, a conveying box 3 is fixedly arranged on the die-casting box 2, a feed port 4 is arranged at the upper end of the die-casting box 2, a guide plate 5 is arranged at the output end of the conveying box 3, the guide plate 5 is inclined, and the lower end of the guide plate 5 extends to above the feed port 4, a discharge box 6 is fixedly arranged on the conveying box 3, and the discharge box 6 contains solid molten material 7, the bottom of the discharge box 6 is connected with a discharge channel 8, the lower end of the discharge channel 8 extends into the conveying box 3, the side wall of the discharge channel 8 is connected with a feed pipe 9, and the output end of the feed pipe 9 is provided with a feeding mechanism.

[0026] The feeding mechanism includes a first roller 10 and a second roller 11 rotatably connected to the inner wall of the conveying box 3, a conveyor belt Ⅰ12 is sleeved on the outer side walls of the first roller 10 and the second roller 11, a third roller 13 and a fourth roller 14 are arranged directly below the first roller 10 and the second roller 11, the third roller 13 and the fourth roller 14 are both rotatably connected to the inner wall of the conveying box 3, and a conveyor belt Ⅱ15 is sleeved on the outer side walls of the third roller 13 and the fourth roller 14, protrusion capsules 16 are equidistantly arranged on the outer side walls of the conveyor belt Ⅰ12 and the conveyor belt Ⅱ15, and the protrusion capsules 16 are filled with electrorheological fluid, a positive plate 17 is arranged between the first roller 10 and the second roller 11, and a negative plate 18 is arranged between the third roller 13 and the fourth roller 14, and the positive plate 17 and the negative plate 18 are respectively connected to the positive and negative poles of an external power supply through a power connection component.

[0027] It should be noted that the positive plate 17 and the negative plate 18 are arranged opposite to each other, and insulating plates are fixedly connected to the side walls of the positive plate 17 and the negative plate 18 that are away from each other. The insulating plates are fixedly installed on the inner wall of the conveying box 3. The insulating plates play a role in shielding the electric field, so that the positive plate 17 and the negative plate 18 only form an electric field in the area between the two sides. The electrorheological fluid is a liquid suspension in an electric field-free environment. In an electric field environment, when the electric field strength reaches a critical value, the electrorheological fluid is solid, that is, when the protrusion capsule 16 moves with the conveyor belt to the area between the positive plate 17 and the negative plate 18, the electrorheological fluid is solid, so that the protrusion capsule 16 is shaped, the solid melt is fixed, and the transportation of the solid melt is more stable.

[0028] The feeding mechanism also includes a motor 19 installed on the side wall of the conveying box 3. The output shaft of the motor 19 is connected to a driving gear 20 through a coupling. The driving gear 20 is fixedly connected to the first roller 10. A driven gear 21 is connected to the third roller 13. The driving gear 20 meshes with the driven gear 21. When the motor 19 is running, it drives the first roller 10 and the driving gear 20 to rotate, and the driving gear 20 drives the driven gear 21 to rotate in the opposite direction, thereby realizing the relative rotation of the conveyor belt I12 and the conveyor belt II15, and stably conveying the solid melt therebetween.

[0029] The power connection assembly includes a turntable 22 fixedly connected to the fourth roller 14, and a plurality of centrifugal cylinders 23 are fixed at equal intervals on the peripheral side wall of the turntable 22. A centrifugal ball 24 is slidably arranged in the centrifugal cylinder 23. The centrifugal ball 24 is movably connected to the inner wall of the centrifugal cylinder 23 through an elastic rope. When the fourth roller 14 drives the turntable 22 to rotate, the centrifugal ball 24 can extend out of the centrifugal cylinder 23 under the action of centrifugal force.

[0030] The power connection assembly also includes a fixed block 26 fixedly connected to the outer wall of the conveying box 3, and a movable block 28 is connected to the fixed block 26 through a reset spring 27. Two guide rods 29 are fixedly connected to the bottom of the movable block 28, and the lower ends of the guide rods 29 are inserted through the fixed block 26. Conductive heads 30 are fixedly connected to the side walls of the fixed block 26 and the movable block 28 that are close to each other. The conductive heads 30 are connected to an external power supply. When the two conductive heads 30 are in contact, the positive plate 17 and the negative plate 18 are energized.

[0031] The lower surface of the movable block 28 is an arc-shaped surface, and the center of the arc-shaped surface falls on the center of the rotating disk 22 , so that the centrifugal ball 24 can slide on the arc-shaped surface of the movable block 28 when rotating.

[0032] A rotating shaft is fixedly arranged on both sides of the feed pipe 9, and the rotating shaft is rotatably connected to the side wall at the bottom opening of the discharge channel 8 through bearings. One end of the feed pipe 9 extends into the discharge channel 8 and is connected to the bottom of the discharge channel 8 through a vibration spring 25. The other end of the feed pipe 9 extends to the input end of the conveyor belt I12 and the conveyor belt II15.

[0033] A cam 31 is fixedly connected to the second rotating roller 11 , a pin 32 is fixedly connected to the side wall of the cam 31 , and a transmission rod 33 is rotatably connected to the pin 32 .

[0034] An arc groove is provided on the side wall of the conveying box 3 , and a connecting rod 34 slides in the arc groove. One end of the connecting rod 34 is fixedly connected to the feed pipe 9 , and the other end is hinged to the transmission rod 33 .

[0035] When the present invention is working, an appropriate amount of solid melt 7 is stored in the discharge box 6, and the solid melt 7 enters the feed pipe 9 through the discharge channel 8, and rolls down to the space between the conveyor belt Ⅰ12 and the conveyor belt Ⅱ15 through the feed pipe 9, and the first roller 10 and the driving gear 20 are driven by the motor 19 to rotate, and the driving gear 20 drives the driven gear 21 to rotate in the opposite direction, thereby realizing the relative rotation of the conveyor belt Ⅰ12 and the conveyor belt Ⅱ15, and stably conveying the solid melt therebetween. After the solid melt 7 is conveyed to the ends of the conveyor belt Ⅰ12 and the conveyor belt Ⅱ15, it passes through the guide plate 5 and the feed port 4 and enters the die casting box 2, realizing automatic loading.

[0036] The electrorheological fluid in the protruding capsule 16 located at the front end of the conveyor belt I 12 and the conveyor belt II 15 is in liquid state. The protruding capsule 16 can be deformed to wrap the solid melt 7. As the conveyor belt runs, when the solid melt wrapped in the protruding capsule 16 moves between the positive plate 17 and the negative plate 18, it is affected by the electric field between the positive plate 17 and the negative plate 18, and the electrorheological fluid changes from liquid to solid, so that the protruding capsule 16 is shaped and the solid melt is fixed, thereby making the transportation of the solid melt more stable and preventing the solid melt from rolling and accumulating on the conveyor belt, which is convenient for the staff to control the feed amount, making the feed amount stable and avoiding changes in the furnace temperature in the melting furnace.

[0037] When the conveyor belts I 12 and II 13 are running to transport the solid melt, the second roller 11 rotates, driving the cam 31 to rotate. The cam 31 drives the feed pipe 9 to reciprocate and vibrate through the transmission rod 33 and the connecting rod 34. On the one hand, it can continuously push the solid melt at the bottom of the discharge channel 8 to move, preventing the solid melt from accumulating and clogging at the bottom outlet end of the discharge channel 8. On the other hand, it can promote the solid melt in the feed pipe 9 to roll down quickly, further avoiding blockage problems and improving feeding efficiency.

[0038] When the conveyor belt I 12 and the conveyor belt II 15 are running to transport the solid melt 7, the fourth roller 14 drives the turntable 22 to rotate. When the turntable 22 drives the centrifugal cylinder 23 to rotate, the centrifugal ball 24 extends out of the centrifugal cylinder 23 under the action of centrifugal force, contacts and slides with the arc surface of the movable block 28, and pushes the movable block 28 to move closer to the fixed block 26. The reset spring 27 is compressed. At this time, the two conductive heads 30 are in contact, so that the positive plate 17 and the negative plate 18 are energized. When the feeding is stopped, the fourth roller 14 and the turntable 22 stop rotating, and the centrifugal ball 24 is pulled back into the centrifugal cylinder 23 by the elastic rope. The movable block 28 is reset under the elastic force of the reset spring 27, so that the two conductive heads 30 are far away from the disconnected contact, and then the positive plate 17 and the negative plate 18 are automatically powered off, without the need for manual control of the on and off, reducing labor costs and saving energy consumption.
