Description

Technical Field

[0001] The present invention relates to the technical field of die-casting machines, and particularly to a gantry of a die-casting machine. Background Art

[0002] During the use of the gantry of a die-casting machine, usually after the gantry is installed, half of the mold, crucible, and extrusion equipment are installed on the gantry. Subsequently, the gantry is moved by a cylinder or hydraulic propulsion equipment. The gantry slides along the chute on the base of the die-casting machine. Finally, the two molds are docked. After docking, the molten metal in the crucible is pressurized and extruded into the two docked molds by the extrusion equipment for die-casting.

[0003] However, usually during this process, the crucible needs to always contain molten metal, which requires continuous feeding of materials into the crucible for melting. Since the feeding hopper of the crucible is relatively large in volume and has a relatively large weight when storing materials inside, it is not convenient to move along with the crucible. After the metal in the crucible is used up, when the metal in the crucible is used up, the gantry needs to move the crucible to the lower part of the feeding hopper for feeding. This not only reduces the remaining temperature in the crucible, but also requires reheating and melting the metal after re-feeding, and to a certain extent reduces the production efficiency.

[0019] As an alternative solution for the gantry of the die-casting machine described in the present invention, the following is provided: an inclined surface is provided on the outer wall of the storage hopper, and the inclined surface is always in contact with the outer wall of the metal braided belt.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In the present invention, in the process of the movement of the crucible, the crucible will drive the metal braided belt to move together, and the movement of the metal braided belt will cause it to continuously slide between the first horizontal pipe and the second horizontal pipe. When the first mold moves towards the second mold, the angle between the metal braided belt and the surface of the crucible gradually decreases. When the first mold moves away from the second mold during demolding, the angle between the metal braided belt and the surface of the crucible gradually increases. And no matter how the crucible moves, the metal braided belt is always clamped between the first horizontal pipe and the second horizontal pipe, so that the outer wall of the metal braided belt is always in contact with the inclined surface. Therefore, when the storage hopper discharges materials, no matter where the crucible is located, the dropped raw materials will slide along the surface of the metal braided belt into the first groove for use.

[0022] In the present invention, the gantry of the die-casting machine has a smaller angle between the metal braided belt and the surface of the crucible as the crucible is closer to the second mold. The up and down reciprocating movement of the second slider will cause the first transverse tube and the second transverse tube of the outer wall to move up and down together. The up and down movement of the first transverse tube and the second transverse tube will cause the metal braided belt between them to shake up and down. The up and down shaking of the metal braided belt can shake the raw material that cannot fall into the first groove due to the gentle slope of the surface into the first groove, and because the lowest point of the wave bend of the track groove gradually increases from right to left, it means that the closer the crucible is to the second mold, although the slope of the metal braided belt will become gentler, the shaking amplitude of the metal braided belt will be greater, which is convenient for feeding into the crucible.

[0023] In the present invention, in the process of the fourth horizontal axis sliding along the inner wall of the track groove, the gantry of the die-casting machine will pass through the contact plate. At this time, the shift plate on the outer wall of the fourth horizontal axis will resist the outer wall of the contact plate, causing the shift plate to be forced to rotate. The shift plate is forced to rotate with the fourth horizontal axis. The rotation of the fourth horizontal axis causes the second slider at one end to rotate. At this time, the second slider is forced to rotate along the inner wall of the fixed ring with the second sliding plate, and the torsion spring is twisted during the rotation, so that the torsion spring is in a twisted state for subsequent resetting. Therefore, the rotation of the second slider at this time will cause the first transverse tube and the second transverse tube to rotate synchronously. At this time, the rotation of the first transverse tube and the second transverse tube will shift the metal braided belt between them, making the metal braided belt tighter.

[0049] A first groove 15 is formed on the inner wall of the crucible 12. A second groove 16 is formed on the inner wall of the first groove 15. A third groove 17 is further formed on the outer wall of the crucible 12. The third groove 17 is communicated with the second groove 16. A first mold 13 is fixed to the outer wall of the second gantry 6, and the third groove 17 is communicated with the first mold 13;

[0050] A second cylinder 9 is installed on the outer wall of the second gantry 6. A plug 10 is fixed to the output end of the second cylinder 9, and the outer contour of the plug 10 matches the inner contour of the third groove 17;

[0051] A support plate 11 is fixedly connected to the outer wall of the die-casting machine main body 1, and a second mold 14 is fixed to the outer wall of the support plate 11;

[0052] An inclined surface 18 is formed on the outer wall of the storage hopper 8, and the inclined surface 18 is always in contact with the outer wall of the metal braid 22.

[0053] In this embodiment: During the use of the existing gantry of the die-casting machine on the market currently, usually after the gantry is installed, half of the mold, crucible, and extrusion equipment are installed on the gantry. Subsequently, the gantry is moved by using a cylinder or a hydraulic propulsion device. The gantry slides along the chute on the base of the die-casting machine. Finally, the two molds are docked. After docking, the molten metal in the crucible is pressurized and extruded into the space where the two docked molds are located by using the extrusion equipment for die-casting. However, usually during this process, there needs to be always molten metal in the crucible, which requires continuous feeding of materials into the crucible for melting. Since the feeding hopper of the crucible is relatively large in volume and the weight during internal storage is also relatively large, it is not convenient to move along with the crucible. After the metal in the crucible is exhausted, when the metal in the crucible is used up, the gantry needs to move the crucible to the lower part of the feeding hopper for feeding. This not only reduces the remaining temperature in the crucible, but also requires reheating and melting the metal after re-feeding, and to a certain extent, reduces the production efficiency;

[0054] To avoid the occurrence of the above situation, when using the gantry of the die-casting machine, first add the metal raw materials into the storage hopper 8 for storage. Subsequently, the motor 20 can be started at any time to drive the first cross shaft 19 to rotate. The rotation of the first cross shaft 19 drives the blocking door 21 to release the blockage of the lower port of the storage hopper 8, so that the raw materials in the storage hopper 8 can fall along the metal braided belt 22 into the first groove 15. Subsequently, the crucible 12 can be continuously started to melt and heat the raw materials in the first groove 15. The melted metal in the first groove 15 enters the third groove 17 through the second groove 16;

[0055] At this time, start the first cylinder 3. The first cylinder 3 drives the second gantry 6 at the output end to move along the chute 5. The second gantry 6 drives the crucible 12 to move synchronously until the first mold 13 on the outer wall of the crucible 12 is tightly docked with the support plate 11. At this time, start the second cylinder 9. The second cylinder 9 drives the plug 10 to press downward into the third groove 17. Since the outer contour of the plug 10 matches the inner contour of the third groove 17, the molten iron in the third groove 17 will be pressurized and pushed into the space at the docking part of the first mold 13 and the second mold 14 during the downward pressing process, thus completing the die-casting;

[0056] In order to supplement the metal raw materials in the crucible 12 at any time during the die-casting process, during the movement of the crucible 12, the crucible 12 will move together with the metal braided belt 22, and the movement of the metal braided belt 22 will cause it to continuously slide between the first horizontal pipe 39 and the second horizontal pipe 40. When the first mold 13 moves towards the second mold 14, the angle between the metal braided belt 22 and the surface of the crucible 12 gradually decreases. When the first mold 13 moves away from the second mold 14 during demolding, the angle between the metal braided belt 22 and the surface of the crucible 12 gradually increases. And no matter how the crucible 12 moves, the metal braided belt 22 is always clamped between the first horizontal pipe 39 and the second horizontal pipe 40, prompting the outer wall of the metal braided belt 22 to always fit on the inclined surface 18. Therefore, when the storage hopper 8 discharges materials, no matter where the crucible 12 is located, the dropped raw materials will slide along the surface of the metal braided belt 22 into the first groove 15 for use;

[0057] Moreover, when the metal braided belt 22 moves with the crucible 12, the metal braided belt 22 will generate a certain pulling force due to sliding between the first horizontal pipe 39 and the second horizontal pipe 40. At this time, the second horizontal shaft 26 at one end of the metal braided belt 22 will be stressed and drive the first slider 24 to slide along the inner wall of the first fixed frame 23, and compress or stretch the first return spring 25 during the sliding process to facilitate subsequent springback and reset;

[0058] During the demolding process, as the crucible 12 moves farther away from the second mold 14, the angle between the metal braided belt 22 and the surface of the crucible 12 becomes smaller. At this time, when the material storage hopper 8 discharges materials onto the surface of the metal braided belt 22, due to the gradually gentler slope, it may cause the raw materials to stay on the surface of the metal braided belt 22 and not fall into the first groove 15. To avoid this situation, when the crucible 12 moves the metal braided belt 22 towards the second mold 14, it will also drive the support frame 7 to move synchronously. However, since the material storage hopper 8 is fixed in place at this time, the movement of the support frame 7 will cause the fourth horizontal shaft 44 and the ball 47 to continuously slide along the inner wall of the track groove 48 opened on the outer wall of the support frame 7. And because the track groove 48 is set as a wavy contour track, at this time, the fourth horizontal shaft 44 and the ball 47 will be guided by the track groove 48 to continuously move up and down reciprocally, so that the fourth horizontal shaft 44 drives the second slider 38 to slide up and down along the outer wall of the second guide rod 36, compressing or stretching the third return spring 37 during the sliding process for subsequent reset. The up and down reciprocating movement of the second slider 38 will drive the first horizontal pipe 39 and the second horizontal pipe 40 on its outer wall to move up and down together. The up and down movement of the first horizontal pipe 39 and the second horizontal pipe 40 will cause the metal braided belt 22 between them to vibrate up and down. The up and down vibration of the metal braided belt 22 can shake the raw materials on the surface that cannot fall into the first groove 15 due to the gentle slope into the first groove 15. And because the lowest point of the wavy bend of the track groove 48 gradually increases from right to left, it means that the closer the crucible 12 is to the second mold 14, although the slope of the metal braided belt 22 will become gentler, the vibration amplitude of the metal braided belt 22 will be larger, facilitating the feeding into the crucible 12;

[0059] During the use of the metal braided belt 22, because the first transverse tube 39 and the second transverse tube 40 move up and down reciprocatingly, the metal braided belt 22 may become loose when moving downward. This will cause the loosened metal braided belt 22 to deform when the raw material falls on the surface of the metal braided belt 22, causing the raw material to sink into the deformed surface of the metal braided belt 22, making it impossible to unload the material. In order to avoid this situation, when the fourth transverse axis 44 slides along the inner wall of the track groove 48, it will pass through the resistance plate 46. At this time, the paddle plate 45 on the outer wall of the fourth transverse axis 44 will resist the outer wall of the resistance plate 46, causing the paddle plate 45 to be forced to rotate. The paddle plate 45 is forced to rotate with the fourth transverse axis 44, and the rotation of the fourth transverse axis 44 drives one end The second slider 38 has a tendency to rotate. At this time, the second slider 38 is subjected to force and drives the second sliding plate 33 to rotate along the inner wall of the fixing ring 32, and the torsion spring 34 is twisted during the rotation, so that the torsion spring 34 is in a twisted state for subsequent reset. Therefore, the rotation of the second slider 38 at this time will drive the first transverse tube 39 and the second transverse tube 40 to rotate synchronously. At this time, the rotation of the first transverse tube 39 and the second transverse tube 40 will move the metal braided belt 22 between them, making the metal braided belt 22 tighter. It should be noted that when the fourth transverse axis 44 rises, the length of the dial plate 45 is sufficient to ensure that the angle between the dial plate 45 and the contact plate 46 is always less than ninety degrees, which is convenient when the fourth transverse axis 44 is subsequently lowered, and can cause the dial plate 45 to rotate after the contact with the contact plate 46;

[0060] In order to make the raw materials passing through the surface of the metal braided belt 22 to be discharged more smoothly, when the fourth horizontal axis 44 and the ball 47 slide along the track groove 48, the ball 47 will continuously contact the hemispherical protrusion 49, and because the hemispherical protrusion 49 is set to a hemispherical shape, the contact will cause the fourth horizontal axis 44 to move a distance away from the track groove 48, which prompts the fourth horizontal axis 44 to press the second sliding plate 33 with the second slider 38, so that the second sliding plate 33 is forced to slide along the inner wall of the second fixed frame 29 with the first sliding plate 30, and compress the second reset spring during the sliding process. The spring 31 is pressed to facilitate subsequent resetting. At this time, the sliding of the second slider 38 will move the first transverse tube 39 and the second transverse tube 40 together, which will cause the two pairs of first transverse tubes 39 and second transverse tubes 40 on both sides to move toward each other, compressing the fourth resetting spring 41 so as to cause the end of the third transverse axis 43 to slide into the inner wall of the first transverse tube 39 and the second transverse tube 40. At this time, the second sliders 38 on both sides also move in opposite directions, and the two second sliders 38 approach each other for a distance to squeeze the metal braided belt 22, so that both sides of the metal braided belt 22 are squeezed at the same time. Since the initial state of the metal braided belt 22 is attached Figure 11As shown, it is in a state where both ends are slightly bent upwards. Therefore, when both ends of the metal braided belt 22 are squeezed, they will continue to bend upwards along the initial bending points. Such repeated bending prompts the raw materials on both sides of the metal braided belt 22 to be shaken, assisting them to fall into the crucible 12 and preventing the raw materials from rubbing against the outer wall of the crucible 12 on the metal braided belt 22 and thus being unable to fall.
