Description

Technical Field

[0001] The invention belongs to the technical field of die-casting equipment, and in particular relates to a die-casting mold for aluminum castings. Background Art

[0002] Aluminum die casting technology has many advantages, which make aluminum die casting an important manufacturing technology in many industries such as automobiles, aerospace, electronics, and communications. Aluminum die casting can produce a large number of complex-shaped parts in a short time, which is suitable for large-scale production. Die castings usually have high dimensional accuracy and good surface finish, which enables them to meet the requirements of tight fit during assembly. Aluminum alloy die casting can produce parts with complex geometric shapes. Waste materials (such as runners, flash, etc.) in the die casting process can be recycled and reused, which improves the utilization rate of materials. Although the initial investment cost of the die casting mold is high, once the mold is ready, the subsequent cost of each part is relatively low, especially in large-scale production.

[0003] Aluminum die-casting is inseparable from die-casting molds. Usually, a one-piece die-casting mold needs to be designed when die-casting small aluminum castings, so that multiple aluminum castings can be cast at one time to improve production efficiency. However, in the actual application of this one-piece die-casting mold, due to the high temperature of the one-piece casting after it is ejected from the mold, a robotic arm is required to take out the die-casting, the one-piece casting is cooled first, and then the aluminum casting is manually broken apart, and then the aluminum casting and the one-piece runner and flash are recovered separately, the one-piece runner and flash are returned to the furnace for reuse, and the aluminum castings are collected and sent to the next production process, which greatly reduces production efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an aluminum casting die-casting mold. The present invention automatically separates the aluminum casting from the flash and the one-piece runner immediately after the one-piece casting is ejected from the mold, and can collect the aluminum casting and the flash separately. The flash can be quickly returned to the furnace for reuse, thereby effectively improving production efficiency.

[0005] The technical solution adopted to solve the above technical problems is: an aluminum casting die-casting mold, comprising a fixed mold assembly, a movable mold assembly and a flipping frame, one side of the fixed mold assembly is fixedly provided with an injection component, the fixed mold assembly is fixedly provided on the ground, the movable mold assembly is provided on the other side of the fixed mold assembly, the other side of the movable mold assembly is fixedly provided with a bottom plate, the bottom plate is symmetrically provided with guide columns, the other end of the guide columns is fixedly connected to the fixed mold assembly, the guide columns penetrate the movable mold assembly, the movable mold assembly is slidably connected to the guide columns, the bottom plate is also fixedly connected with a hydraulic push rod, the other end of the hydraulic push rod is fixedly connected to the movable mold assembly, and the flipping frame is rotatably connected to the fixed mold assembly;

[0006] The horizontal displacement of the movable mold assembly can drive the turning frame;

[0007] A material receiving mechanism is provided below the fixed mold assembly and the movable mold assembly;

[0008] Material collecting mechanisms are arranged on both sides of the material bearing mechanism, and the horizontal displacement of the movable mold assembly can drive the material collecting mechanisms;

[0009] A material distribution mechanism is arranged below the material receiving mechanism, and the horizontal displacement of the movable mold assembly can drive the material distribution mechanism.

[0010] Through the above technical scheme, at the beginning of die casting, the movable mold assembly slides horizontally and closes the mold with the fixed mold assembly, and the injection component injects aluminum alloy liquid into the mold cavity after the mold is closed. After the aluminum alloy liquid is solidified and finalized, the movable mold assembly slides horizontally away from the fixed mold assembly to realize mold opening. During the mold opening process, the movable mold assembly drives the material turning frame to rotate, so that the one-piece casting falls on the material receiving mechanism, and then the inside of the movable mold assembly and the fixed mold assembly are cleaned. The water flow generated by the cleaning can cool the one-piece casting on the material receiving mechanism, and then the mold release agent is sprayed on the inside of the movable mold assembly and the fixed mold assembly. The movable mold assembly and the fixed mold assembly are closed again. During the mold closing process, the collecting mechanism presses the flash of the one-piece casting on the material receiving mechanism, the dividing mechanism rises to separate the aluminum casting, and the aluminum casting falls and is collected and recovered. Finally, the next batch of one-piece castings in the movable mold assembly and the fixed mold assembly are solidified and formed, and the mold is opened again. The collecting mechanism takes away the flash for unified recovery, and the new one-piece casting falls on the material receiving mechanism. Such a cycle can effectively improve production efficiency.

[0011] Furthermore, a first rack is fixedly connected to the rear side of the movable mold assembly, a driven gear is fixedly connected to the rotating shaft of the flipping frame, and the first rack is meshed with the driven gear.

[0012] Through the above technical solution, since the first rack is meshed with the driven gear, the horizontal sliding of the movable mold assembly can drive the flipping frame to rotate. When the movable mold assembly slides horizontally toward the fixed mold assembly, the flipping frame flips toward the fixed mold assembly. When the movable mold assembly slides horizontally toward the fixed mold assembly, the flipping frame flips toward the movable mold assembly.

[0013] Furthermore, the material collecting mechanism includes a first conveyor belt, a second conveyor belt, a first material pulling frame, a second material pulling frame and a transmission gear. The first conveyor belt is arranged on one side of the material receiving mechanism, and the second conveyor belt is arranged on the other side of the material receiving mechanism. The first material pulling frame is arranged above the first conveyor belt, and the second material pulling frame is arranged above the second conveyor belt. The second conveyor belt is symmetrically rotated on both sides thereof and is connected with a transmission gear.

[0014] Through the above technical solution, the first conveyor belt and the second conveyor belt can be arranged to convey away the flash under the first material drawing frame and the second material drawing frame, so as to facilitate unified recovery.

[0015] Furthermore, the fixed mold assembly is fixedly connected to a track groove on the side away from the material receiving mechanism, the second material pulling frame is fixedly connected to a guide rail on the side away from the material receiving mechanism, the guide rail is slidably connected to the track groove, and the first material pulling frame is fixedly connected to the movable mold assembly.

[0016] Through the above technical solution, since the guide rail is slidably connected to the track groove, the first drawing frame is fixedly connected to the movable mold assembly, so that the first drawing frame can slide horizontally with the movable mold assembly, and the second drawing frame can slide horizontally in the track groove.

[0017] Furthermore, a third rack is fixedly connected to the lower part of the guide rail, a second rack is fixedly connected to the lower part of the movable mold assembly, the third rack is meshed with the upper part of the transmission gear, and the second rack is meshed with the lower part of the transmission gear.

[0018] Through the above technical solution, since the third rack is meshed with the upper part of the transmission gear and the second rack is meshed with the lower part of the transmission gear, the horizontal sliding of the second rack can drive the transmission gear to rotate, and the rotation of the transmission gear can drive the third rack to slide horizontally;

[0019] That is, when the first material drawing frame slides horizontally with the movable mold assembly toward the fixed mold assembly, the second rack slides horizontally toward the fixed mold assembly, the second rack drives the transmission gear to rotate forward, and the transmission gear rotates forward to drive the third rack to slide horizontally toward the movable mold assembly, so that the first material drawing frame and the second material drawing frame are brought closer to each other;

[0020] On the contrary, when the first material pulling frame slides horizontally toward the movable mold assembly along with the movable mold assembly, the second rack slides horizontally toward the movable mold assembly, the second rack drives the transmission gear to reverse, and the reverse transmission gear drives the third rack to slide horizontally toward the fixed mold assembly, thereby separating the first material pulling frame from the second material pulling frame.

[0021] Furthermore, the material supporting mechanism includes a loading platform and a material receiving box, the loading platform is fixedly connected to the top of the material receiving box, the material receiving box is fixedly connected to the ground, the top of the loading platform is rotatably connected to multiple rollers, the top of the loading platform is symmetrically provided with inner slopes on the front and rear sides, and the two sides of the loading platform are symmetrically provided with outer slopes.

[0022] Through the above technical scheme, since the top of the loading platform is rotatably connected with multiple rollers, the inner slopes are symmetrically arranged on the front and rear sides of the top of the loading platform, and the outer slopes are symmetrically arranged on both sides of the loading platform, so that the one-piece casting can easily fall into the top of the loading platform, and the cut flash can easily slide on the top of the loading platform, and then be discharged through the outer slope for unified recovery.

[0023] Furthermore, a baffle is hingedly connected on one side of the first material pulling frame and the second material pulling frame close to the material receiving mechanism, and a friction groove is arranged at the bottom of the first material pulling frame and the second material pulling frame.

[0024] Through the above technical scheme, since the first material drawing frame and the second material drawing frame are hinged with a baffle plate on one side close to the material receiving mechanism, and a torsion spring is arranged at the hinge of the baffle plate, when the one-piece casting falls onto the loading platform, the baffle plate and the inner slope can limit the one-piece casting on the top of the loading platform, and when the first material drawing frame and the second material drawing frame slide horizontally close to each other, the flipping of the baffle plate does not hinder the first material drawing frame and the second material drawing frame from approaching each other, and then the first material drawing frame and the second material drawing frame can press down the flash of the one-piece casting, so as to facilitate the rising and cutting of the material dividing mechanism;

[0025] When the first pulling frame and the second pulling frame slide horizontally away from each other, the friction groove and the roller can cooperate to pull the cut flash from the top of the loading platform to the outer slope, and finally fall on the first conveyor belt and the second conveyor belt for convenient unified recovery.

[0026] Furthermore, a crossbeam is fixedly connected to the top of the material receiving box, a gear ring is rotatably connected to the crossbeam, vertical rails are symmetrically fixedly arranged on both sides of the material receiving box, and a discharge slope is fixedly arranged at the bottom of the material receiving box.

[0027] Through the above technical solution, since a discharge slope is fixedly arranged at the bottom of the receiving box and an opening is arranged at the front side of the receiving box, the aluminum castings dropped into the receiving box can be discharged through the opening for easy collection.

[0028] Furthermore, the material dividing mechanism includes a base plate, a slitting cylinder, a slitting tool, a vertical rod and a threaded rod, the slitting cylinder is symmetrically arranged on the top of the base plate, the slitting tool is fixedly connected in the middle of the top of the base plate, the base plate is symmetrically fixedly connected with vertical rods on both sides, the threaded rod is fixedly connected in the middle of the bottom of the base plate, the threaded rod passes through the gear ring and the cross beam, the threaded rod is threadedly connected to the gear ring, the vertical rod is slidably connected to the vertical rail, and an avoidance groove is arranged in the middle of the loading platform, and the avoidance groove can allow the slitting tool to pass through.

[0029] Through the above technical solution, since the slitting cylinder is symmetrically arranged on the top of the base plate, and the slitting tool is fixedly connected to the middle of the top of the base plate, the slitting cylinder rises to separate the conjoined casting pressing the flash, and the aluminum casting falls into the receiving box through the slitting cylinder;

[0030] Since the threaded rod passes through the gear ring and the crossbeam, the threaded rod is threadedly connected to the gear ring, and the vertical rod is slidably connected to the vertical rail, the rotation of the gear ring can drive the threaded rod to rotate, and the rotation of the threaded rod can drive the base plate to rise and fall;

[0031] Since the avoidance groove allows the slitting tool to pass through, the slitting tool can separate the flash and facilitate the discharge of the flash.

[0032] Furthermore, a fourth rack is fixedly connected to the bottom of the movable mold assembly, and the fourth rack is meshed with the gear ring.

[0033] Through the above technical solution, since the fourth rack is fixedly connected to the bottom of the movable mold assembly, the fourth rack is meshed with the gear ring, so that when the fourth rack slides horizontally with the movable mold assembly toward the fixed mold assembly, the fourth rack drives the gear ring to rotate forward, the gear ring rotates forward and drives the threaded rod to rotate forward, and the threaded rod rotates forward and drives the base plate to rise, so that the slitting cylinder and the slitting tool rise and separate the conjoined casting;

[0034] On the contrary, when the fourth rack slides horizontally toward the movable mold assembly along with the movable mold assembly, the fourth rack drives the gear ring to reverse, the gear ring reverses to reverse the threaded rod, and the threaded rod reverses to drive the substrate to descend, thereby realizing the slitting cylinder and the slitting tool to descend.

[0035] The beneficial effects of the present invention are as follows:

[0036] (1) In the present invention, the movable mold assembly slides horizontally to close the mold with the fixed mold assembly, and the injection component injects aluminum alloy liquid into the mold cavity after closing the mold. After the aluminum alloy liquid solidifies and takes shape, the movable mold assembly slides horizontally away from the fixed mold assembly to open the mold. During the mold opening process, the movable mold assembly drives the material turning frame to rotate, so that the one-piece casting falls onto the material receiving mechanism, and then the inside of the movable mold assembly and the fixed mold assembly are cleaned. The water flow generated by the cleaning can cool the one-piece casting on the material receiving mechanism, which not only effectively reduces the energy required for cooling, but also saves the need for a mechanical arm to take the material, effectively reducing costs;

[0037] (2) In the present invention, the first material pulling frame and the second material pulling frame are close to each other, and then the first material pulling frame and the second material pulling frame can press the flash of the one-piece casting. At the same time, since the fourth rack is fixedly connected to the bottom of the movable mold assembly, the fourth rack is meshed with the gear ring, so that when the fourth rack slides horizontally with the movable mold assembly toward the fixed mold assembly, the fourth rack drives the gear ring to rotate forward, and the gear ring drives the threaded rod to rotate forward, and the threaded rod drives the base plate to rise, so that the slitting cylinder and the slitting tool can rise and separate the one-piece casting, and the aluminum casting can be automatically separated from the flash immediately after the one-piece casting is ejected from the mold, thereby effectively improving production efficiency;

During the mold closing process, the collecting mechanism 5 presses the flash of the one-piece casting on the receiving mechanism 4, and the dividing mechanism 6 rises to separate the aluminum castings, and the aluminum castings fall and are collected. Finally, the next batch of one-piece castings in the movable mold component 2 and the fixed mold component 1 are solidified and formed, and the mold is opened again.

[0070] When the first pulling frame 53 and the second pulling frame 54 slide horizontally away from each other, the friction groove and the roller 411 cooperate to pull the cut burrs from the top of the loading platform 41 to the outer slope 413, and finally drop them onto the first conveyor belt 51 and the second conveyor belt 52 for convenient unified recovery.

[0073] A fourth rack 23 is also fixedly connected to the bottom of the movable mold assembly 2 , and the fourth rack 23 is meshed with the gear ring 421 .

[0074] In this embodiment, since the slitting cylinder 62 is symmetrically arranged on the top of the base plate 61, and the slitting tool 63 is fixedly connected to the middle of the top of the base plate 61, the slitting cylinder 62 rises to separate the conjoined castings pressing the flash, and the aluminum castings fall into the receiving box 42 through the slitting cylinder 62;

[0075] Since the threaded rod 65 passes through the gear ring 421 and the crossbeam, the threaded rod 65 is threadedly connected to the gear ring 421, and the vertical rod 64 is slidably connected to the vertical rail 43, the rotation of the gear ring 421 can drive the threaded rod 65 to rotate, and the rotation of the threaded rod 65 can drive the base plate 61 to rise and fall;

[0076] Since the avoidance groove 414 allows the slitting tool 63 to pass through, the slitting tool 63 can separate the flash, making it easier to discharge the flash.

[0077] When the fourth rack 23 slides horizontally with the movable mold assembly 2 toward the fixed mold assembly 1, the fourth rack 23 drives the gear ring 421 to rotate forward, the gear ring 421 rotates forward to drive the threaded rod 65 to rotate forward, and the threaded rod 65 rotates forward to drive the base plate 61 to rise, so that the slitting cylinder 62 and the slitting tool 63 rise to separate the conjoined casting;

[0078] On the contrary, when the fourth rack 23 slides horizontally with the movable mold assembly 2 toward the movable mold assembly 2, the fourth rack 23 drives the gear ring 421 to reverse, the gear ring 421 reverses and drives the threaded rod 65 to reverse, the threaded rod 65 reverses and drives the base plate 61 to descend, so that the slitting cylinder 62 and the slitting tool 63 descend.

[0079] Working principle:

[0080] During operation, the movable mold assembly 2 slides horizontally to close the mold with the fixed mold assembly 1, and the injection component 11 injects aluminum alloy liquid into the mold cavity after the mold is closed. After the aluminum alloy liquid is solidified and fixed, the movable mold assembly 2 slides horizontally away from the fixed mold assembly 1 to open the mold;

[0081] During the mold opening process, the movable mold assembly 2 slides horizontally away from the fixed mold assembly 1, and the turning frame 3 turns over toward the movable mold assembly 2, so that the conjoined casting falls onto the material receiving mechanism 4, and then the movable mold assembly 2 and the fixed mold assembly 1 are cleaned inside. The water flow generated by the cleaning can cool the conjoined casting on the material receiving mechanism 4, and then the mold release agent is sprayed inside the movable mold assembly 2 and the fixed mold assembly 1, and the movable mold assembly 2 and the fixed mold assembly 1 are molded again;

[0082] During the mold closing process, the first material drawing frame 53 slides horizontally with the movable mold assembly 2 toward the fixed mold assembly 1, and the second rack 22 slides horizontally toward the fixed mold assembly 1. The second rack 22 drives the transmission gear 55 to rotate forward, and the transmission gear 55 rotates forward to drive the third rack 542 to slide horizontally toward the movable mold assembly 2, so that the first material drawing frame 53 and the second material drawing frame 54 are brought closer to each other.

[0083] When the one-piece casting falls onto the loading platform 41, the baffle 56 and the inner slope 412 can limit the one-piece casting on the top of the loading platform 41, and when the first drawing frame 53 and the second drawing frame 54 slide horizontally toward each other, the baffle 56 flips and does not prevent the first drawing frame 53 and the second drawing frame 54 from approaching each other, and then the first drawing frame 53 and the second drawing frame 54 can press the flash of the one-piece casting;

[0084] At this time, the fourth rack 23 slides horizontally with the movable mold assembly 2 toward the fixed mold assembly 1, and the fourth rack 23 drives the gear ring 421 to rotate forward, and the gear ring 421 rotates forward to drive the threaded rod 65 to rotate forward, and the threaded rod 65 rotates forward to drive the base plate 61 to rise, so that the slitting cylinder 62 and the slitting tool 63 rise to separate the conjoined casting;

[0085] The aluminum castings fall into the receiving box 42 through the slitting cylinder 62. Since a discharge slope 422 is fixedly provided at the bottom of the receiving box 42 and an opening is provided at the front side of the receiving box 42, the aluminum castings falling into the receiving box 42 can be discharged through the opening for easy collection.

[0086] Then, the next batch of conjoined castings in the movable mold assembly 2 and the fixed mold assembly 1 are solidified and formed, and the mold is opened again. During the mold opening process, the first pulling frame 53 and the second pulling frame 54 slide horizontally away from each other, and the friction groove and the roller 411 cooperate to pull the cut flash from the top of the loading platform 41 to the outer slope 413, and finally fall on the first conveyor belt 51 and the second conveyor belt 52, which is convenient for unified recycling, and the new conjoined casting falls onto the material receiving mechanism 4, and this cycle can effectively improve production efficiency.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
