Description

Technical Field

[0001] The utility model mainly relates to the technical field of die castings, and in particular to a clamping device for producing die castings. Background Art

[0002] Die casting is a kind of pressure casting part, which is made by using a pressure casting machine equipped with a casting mold to die-cast liquid metal through a casting machine.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] The clamping device of the prior art usually clamps by pushing the clamping plates against each other through the electric push rods on both sides, but thin-walled aluminum die-castings usually need to be processed at different positions during processing. After clamping in the prior art, the thin-walled aluminum die-castings are fixed, and it is difficult to adjust the processing angle of the thin-walled aluminum die-castings. The flexibility and convenience during use are low, and the practicality is poor. Patent No. 202321461422.X discloses a clamping device suitable for thin-walled aluminum die-castings, including: a main body mechanism, an adjustment clamping mechanism and a waste collection mechanism, the adjustment clamping mechanism is located at the left end of the main body mechanism, the waste collection mechanism is located on the right side of the adjustment clamping mechanism, the main body mechanism includes a fixed base, a support foot and a support plate, the support foot is fixedly mounted on the lower end of the fixed base, the support plate is fixedly mounted on the upper end of the fixed base, the adjustment clamping mechanism includes an adjustment motor and a transmission rod, and the adjustment motor is fixedly mounted on the left end of the support plate. The clamping device suitable for thin-walled aluminum die-castings can adjust the angle of the clamped thin-walled aluminum die-castings by installing an adjustable clamping mechanism, so that the thin-walled aluminum die-castings can be adjusted to different angles according to the processing requirements during processing, making them more practical during use. Although the application achieves the clamping and fixing of die-castings, some die-castings are relatively heavy. During the processing of die-castings, the die-castings are easy to move downward by clamping at one position alone; secondly, the waste chips generated by the processing automatically slide downward through the guiding inclined plate, but the waste chips are also easily adsorbed on the inclined plate due to static electricity and cannot slide down autonomously, resulting in incomplete waste chip treatment.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0032] In this embodiment, the first clamping mechanism 3 includes a cylinder 301, which is fixedly installed above the inner wall of the mounting frame 2. The end of the cylinder 301 actuator rod is connected to a push plate 302, and the push plate 302 is connected to a first clamping plate 304 through multiple springs 303. The first clamping plate 304 realizes the clamping and fixing of the two ends of the die-casting.

[0033] It should be noted that the die-casting is placed between the two first clamping plates 304, and the two push plates 302 are pushed toward the ends of the die-casting by extending the actuator rod of the cylinder 301 until the first clamping plates 304 clamp the two ends of the die-casting. Under the recovery of the compression force of the spring 303, the first clamping plates 304 are more stably clamped on the two ends of the die-casting.

[0034] In this embodiment, the second clamping mechanism 4 includes a fixed plate 401, which is fixedly connected to the lower rear side of the inner wall of the installation frame 2. A fixed cylinder 402 is connected to the middle of the top wall of the fixed plate 401, and a threaded column 403 is threadedly connected to the inner side of the fixed cylinder 402.

The outer side of the bidirectional screw 406 is symmetrically threadedly connected to a movable block 408, and the bottom of the movable block 408 slides on the inner side of the limiting groove 405. The top wall of the movable block 408 is connected to a second clamping plate 409, and the second clamping plate 409 realizes the clamping and fixing of the front and rear side walls of the middle part of the die casting.

[0035] It should be noted that the rotation of the threaded column 403 drives the limit plate 404 to be lifted horizontally upward, so that the two second clamping plates 409 are located on the front and rear side walls of the die-casting. At the same time, the first motor 407 is turned on to drive the bidirectional screw 406 to rotate. The bidirectional screw 406 drives the two movable blocks 408 to slide inside the limit groove 405 and approach the side wall of the die-casting until the second clamping plates 409 are stably clamped on the front and rear side walls of the die-casting, thereby improving the firmness of the clamping of the die-casting.

[0036] In this embodiment, the cleaning mechanism 5 also includes a second motor 502, which is installed at the lower part of one side of the outer wall of the installation frame 2. The output end of the second motor 502 is connected to a rotating rod 503, one end of the rotating rod 503 rotates on the inner wall of the installation frame 2, and both ends of the rotating rod 503 are connected to gears 504. The inner bottom wall of the installation frame 2 is symmetrically slidably connected to a rack 505, and the gear 504 and the rack 505 are meshed with each other. The two ends of the cleaning plate 501 are respectively connected to the ends of the two racks 505.

[0037] It should be noted that, when the second motor 502 is turned on, the rotating rod 503 is driven to rotate, the rotating rod 503 drives the two gears 504 to rotate, the gear 504 drives the rack 505 meshing with it to move forward, and the rack 505 drives the cleaning plate 501 to move forward. The movement of the cleaning plate 501 can push out the waste debris that falls on the bottom wall of the installation frame 2.

[0038] In this embodiment, an inclined plate 6 is connected to the bottom of the front side wall of the mounting frame 2, a fixed box 7 is fixedly connected to the front side wall of the bottom plate 1, a movable collecting box 8 is movably installed on the inner side of the fixed box 7, one side of the inclined plate 6 extends to an opening on one side of the movable collecting box 8, a pull rod 9 is fixedly connected to the upper part of the front side wall of the movable collecting box 8, baffles 10 are movably connected on both sides of the fixed box 7, and the inner wall of the baffle 10 abuts against the lower part of the front side wall of the movable collecting box 8.

[0039] It should be noted that the waste chips fall into the movable collection box 8 through the inclined plate 6. When the waste chips are fully collected, the baffles 10 on both sides can be moved outward, and then the pull rod 9 is pulled to move the movable collection box 8 out from the fixed box 7 to complete the collection and transfer of the waste chips.

[0040] In this embodiment, a spray pipe 11 is installed on one side of the top wall of the fixing box 7 , and the spray pipe 11 can be connected to an external pipeline. A plurality of spray heads 1101 are evenly arranged at the bottom of the spray pipe 11 .

[0041] It should be noted that by conveying water to the inside of the spray pipe 11 and spraying water mist onto the movable collection box 8 through multiple spray heads 1101, the flying of waste debris and dust can be effectively suppressed.

[0042] The working principle of the utility model is as follows: the die casting is placed between the two first clamping plates 304, and the two push plates 302 are pushed toward the ends of the die casting by extending the actuator rod of the cylinder 301 until the first clamping plates 304 clamp the two ends of the die casting, and under the recovery of the compressed elastic force of the spring 303, the first clamping plates 304 are more stably clamped at the two ends of the die casting, and then the limiting plates 404 are lifted upward horizontally by the rotation of the threaded column 403, so that the two second clamping plates 409 are located at the front and rear side walls of the die casting, and at the same time, the first motor 407 is turned on to drive the bidirectional screw 406 to rotate, and the bidirectional screw 406 drives the two movable blocks 408 to slide inside the limiting groove 405 and approach the side wall of the die casting, until the second clamping plates 409 are stably clamped on the front and rear side walls of the die casting, thereby improving the firmness of clamping the die casting; after the die casting is processed The waste generated after the completion will fall on the inner bottom wall of the installation frame 2. At this time, the second motor 502 is turned on to drive the rotating rod 503 to rotate, and the rotating rod 503 drives the two gears 504 to rotate. The gear 504 drives the rack 505 meshing with it to move forward, and the rack 505 drives the cleaning plate 501 to move forward. The movement of the cleaning plate 501 can push the waste debris that has fallen on the inner bottom wall of the installation frame 2 out, and it falls into the inside of the movable collecting box 8 through the inclined plate 6. At the same time that the waste debris enters the inside of the movable collecting box 8, by conveying water to the inside of the spray pipe 11 and spraying water mist on the top of the movable collecting box 8 through multiple spray heads 1101, the waste debris and dust can be effectively suppressed from being raised. When the waste debris is fully collected, the baffles 10 on both sides can be moved outward, and then the pull rod 9 is pulled to move the movable collecting box 8 out from the inside of the fixed box 7 to complete the collection and transfer of the waste debris.

[0043] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
