Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, specifically a positioning device for die casting molds. Background Technology

[0002] In modern industrial production, die casting is a highly efficient metal forming process. The die casting mold is a key tool in die casting production, and its performance directly affects the quality, production efficiency, and cost of die-cast products. During the die casting process, the moving and fixed molds need to be precisely positioned to ensure the dimensional accuracy, surface quality, and internal structural integrity of the die-cast parts. Existing die casting mold positioning devices mostly use a single guide column or bolt fixing structure, which suffers from insufficient positioning stability and poor adjustment flexibility. When changing to different mold specifications, traditional positioning structures require adjusting the fixing components one by one, which is cumbersome and time-consuming, making it difficult to meet the rapid switching requirements of multiple mold types in mass production. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a positioning device for die-casting molds to solve the problems mentioned in the background. This utility model has a novel structure. By using four clamping blocks to simultaneously clamp the stationary mold from all four sides, combined with the buffering effect of the clamping pads, it can effectively reduce the displacement of the stationary mold caused by force during the die-casting process. The cooperation between the auxiliary positioning cone and the cone groove further improves the mold closing accuracy of the moving and stationary molds. The cooperation between the adjusting plate and the fixing bolts can quickly lock the clamping angle without adjusting the fixing components one by one, shortening the mold change time and meeting the needs of rapid switching between multiple molds in mass production.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for a die-casting mold, comprising a die-casting platform, a stationary mold above the die-casting platform, two opposing first clamping blocks and a second clamping block above the die-casting platform, the two first clamping blocks and the second clamping block being respectively disposed on the four sides of the stationary mold, a positioning component being disposed between the first clamping blocks and the second clamping blocks and the die-casting platform, uprights being fixedly connected to the four corners above the die-casting platform, lifting plates being slidably fitted on the four uprights, and a moving mold cooperating with the stationary mold being fixedly installed at the bottom of the lifting plates.

[0005] Furthermore, support legs are fixedly connected to the four corners of the bottom of the die-casting platform, and fixed plates are fixedly connected to the top of the four uprights. A hydraulic rod is fixedly installed in the middle of the fixed plate, and one end of the telescopic shaft of the hydraulic rod is fixedly connected to the top of the lifting plate.

[0006] Furthermore, both sides of the moving mold are fixedly connected with fixing strips, and the bottom of both fixing strips is fixedly connected with auxiliary positioning cones. The two sides of the stationary mold are provided with auxiliary positioning cone grooves that cooperate with the auxiliary positioning cones.

[0007] Furthermore, clamping pads are fixedly connected to the two first clamping blocks and the second clamping block on the side facing the stationary mold. Slide grooves are opened downward on the upper side of the die-casting table corresponding to its four sides. Slider blocks that slide in cooperation with the slide grooves are fixedly connected to the bottom of the two first clamping blocks and the second clamping block. A rotating groove that communicates with the slide grooves is opened upward on the bottom of the die-casting table.

[0008] Furthermore, the positioning component includes a first rotating disk and a second rotating disk that are rotatably fitted on the inner wall of the rotating groove. Both sides of the first rotating disk and the second rotating disk have two strip-shaped grooves arranged in a circumferential array. The other two sides of the first rotating disk and the second rotating disk have through slots, and the through slots on the first rotating disk and the second rotating disk correspond to the strip-shaped grooves on them.

[0009] Furthermore, the bottom of the slider is fixedly connected with connecting posts, two of which rotate and slide with two strip grooves on the first rotating disk, and the other two connecting posts rotate and slide with two strip grooves on the second rotating disk. The first and second rotating disks are stacked, and the rotation of the first and second rotating disks in the rotating grooves does not affect each other.

[0010] Furthermore, a fixed frame is fixedly connected to the bottom of the die-casting table, and an adjusting block is slidably fitted below the fixed frame. An adjusting screw is rotatably fitted to one side of the adjusting block. A threaded sleeve is fixedly connected to one of the support legs, which is fitted around the adjusting screw and threadedly fitted thereto. Both ends of the adjusting block are rotatably fitted with strip-shaped groove frames. The inner wall of one strip-shaped groove frame is rotatably and slidably fitted with the connecting post below the first clamping block, and the inner wall of the other strip-shaped groove frame is rotatably and slidably fitted with the connecting post below the second clamping block.

An adjusting disc is fixedly connected to the end of the rotating shaft, and a fixing bolt is threaded onto the adjusting disc. Both ends of the adjusting block are provided with multiple fixing slots that engage with the fixing bolts.

[0012] The beneficial effects of this utility model are:

[0013] 1. The positioning device of this die-casting mold uses four clamping blocks to simultaneously clamp the stationary mold from all four sides. Combined with the buffering effect of the clamping pad, it can effectively reduce the displacement of the stationary mold caused by force during the die-casting process. The cooperation between the auxiliary positioning cone and the cone groove further improves the mold closing accuracy of the moving and stationary molds. The cooperation between the adjusting plate and the fixing bolt can quickly lock the clamping angle without adjusting the fixing components one by one, shortening the mold change time and meeting the needs of rapid switching of multiple molds in mass production.

[0014] 2. The positioning device of this die-casting mold adjusts the angle of the strip frame by rotating the adjusting disc around the rotating shaft, and then screws the fixing bolt into the corresponding fixing groove to lock it. The position of the clamping block can be adjusted simultaneously to adapt to molds of different sizes. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 5This utility model provides a technical solution: a positioning device for a die-casting mold, including a die-casting table 1, a stationary mold 3 above the die-casting table 1, two opposing first clamping blocks 4a and second clamping blocks 4b above the die-casting table 1, the two first clamping blocks 4a and second clamping blocks 4b respectively arranged on the four sides of the stationary mold 3, a positioning component 5 between the first clamping blocks 4a and second clamping blocks 4b and the die-casting table 1, and uprights 6 fixedly connected to the four corners above the die-casting table 1, with lifting plates 9 slidably fitted on the four uprights 6, and a moving mold 10 cooperating with the stationary mold 3 fixedly installed at the bottom of the lifting plates 9.

[0023] In this embodiment, support legs 2 are fixedly connected to the four corners of the bottom of the die-casting table 1. Fixed plates 7 are fixedly connected to the top of the four uprights 6. A hydraulic rod 8 is fixedly installed in the middle of the fixed plate 7. One end of the telescopic shaft of the hydraulic rod 8 is fixedly connected to the top of the lifting plate 9. Fixed strips 11 are fixedly connected to both sides of the moving mold 10. Auxiliary positioning cones 12 are fixedly connected to the bottom of the fixed strips 11 on both sides. Auxiliary positioning cone grooves 13 that cooperate with the auxiliary positioning cones 12 are opened downward on both sides of the stationary mold 3. Clamping pads 14 are fixedly connected to the side of the two first clamping blocks 4a and the second clamping blocks 4b facing the stationary mold 3. Sliding grooves 15 are opened downward on the upper side of the die-casting table 1 corresponding to its four sides. Sliding blocks 16 that slide and cooperate with the sliding grooves 15 are fixedly connected to the bottom of the two first clamping blocks 4a and the second clamping blocks 4b. A rotating groove 17 that communicates with the sliding grooves 15 is opened upward on the bottom of the die-casting table 1.

[0024] Specifically, when the hydraulic rod 8 is activated, its telescopic shaft pushes the lifting plate 9 down along the upright 6, causing the moving mold 10 to descend. The auxiliary positioning cones 12 at the bottom of the fixing strips 11 on both sides of the moving mold 10 precisely match the auxiliary positioning cone grooves 13 of the stationary mold 3, correcting the mold closing deviation and achieving precise alignment and fitting of the moving and stationary molds.

[0025] In this embodiment, the positioning component 5 includes a first rotating disk 501 and a second rotating disk 502 rotatably fitted on the inner wall of the rotating groove 17. Two strip-shaped grooves 503 are arranged in a circumferential array on both sides of the first rotating disk 501 and the second rotating disk 502. Through slots 504 are provided on the other two sides of the first rotating disk 501 and the second rotating disk 502. The through slots 504 on the first rotating disk 501 and the second rotating disk 502 correspond to the strip-shaped grooves 503 on them. Connecting posts 505 are fixedly connected to the bottom of the slider 16. Two of the connecting posts 505 rotate and slide with the two strip-shaped grooves 503 on the first rotating disk 501, and the other two connecting posts 505 rotate and slide with the two strip-shaped grooves 503 on the second rotating disk 502. The first rotating disk 501 and the second rotating disk 502 are stacked, and their rotation within the rotating groove 17 does not affect each other. The bottom of the die-casting table 1 is fixed... A fixed frame 506 is fixedly connected to the support 2. An adjusting block 507 is slidably fitted below the fixed frame 506. An adjusting screw 508 is rotatably fitted to one side of the adjusting block 507. A threaded sleeve 509 is fixedly connected to one of the support legs 2, sleeved around the adjusting screw 508 and threadedly fitted thereto. Both ends of the adjusting block 507 are rotatably fitted with strip-shaped groove frames 510. The inner wall of one of the strip-shaped groove frames 510 is rotatably and slidably fitted with the connecting post 505 below the first clamping block 4a. The inner wall of the other strip-shaped groove frame 510 is rotatably and slidably engaged with the connecting post 505 below the second clamping block 4b. One side of each end of the two strip-shaped groove frames 510 is fixedly connected with a rotating shaft 511 that is rotatably engaged with both ends of the adjusting block 507. An adjusting disc 512 is fixedly connected to the end of the rotating shaft 511. A fixing bolt 513 is threaded onto the adjusting disc 512. Both ends of the adjusting block 507 are provided with multiple fixing grooves 514 that engage with the fixing bolts 513.

[0026] Specifically, by rotating the adjusting screw 508, which helically drives within the threaded sleeve 509, the adjusting block 507 slides along the fixed frame 506. The strip-shaped groove frames 510 at both ends of the adjusting block 507 respectively drive the corresponding connecting column 505 to move. The connecting column 505 slides along the slide groove 15 via the slider 16, simultaneously driving the first rotating disk 501 and the second rotating disk 502 to rotate within the rotating groove 17. Since the connecting column 505 slides in conjunction with the strip groove 503 on the rotating disk, the rotation of the rotating disk causes the two first clamping blocks 4a and the two second clamping blocks 4b to move closer synchronously along the four sides of the stationary mold 3 until the clamping pad 14 is tightly attached to the outer wall of the stationary mold 3 to complete the fixation. If it is necessary to adapt to molds of different specifications, the angle of the strip-shaped groove frame 510 can be adjusted by rotating the adjusting disk 512, and then the fixing bolt 513 can be screwed into the corresponding fixing groove 514 to lock.

[0027] When using this die-casting mold positioning device, first place the stationary mold 3 on the die-casting table 1, then rotate the adjusting screw 508, which drives the screw screw 509 in a spiral motion, pushing the adjusting block 507 to slide along the fixed frame 506. The strip-shaped groove frames 510 at both ends of the adjusting block 507 respectively drive the corresponding connecting column 505 to move. The connecting column 505 drives the slider 16 to slide along the slide groove 15, and at the same time drives the first rotating disk 501 and the second rotating disk 502 to rotate in the rotating groove 17. Since the connecting column 505 slides in the strip-shaped groove 503 on the rotating disk, the rotation of the rotating disk causes the two first clamping blocks 4a and the two second clamping blocks 4b to move along the stationary mold 3. The four sides move closer together until the clamping pad 14 is tightly attached to the outer wall of the stationary mold 3 and fixed. If different mold specifications need to be adapted, the angle of the strip frame 510 can be adjusted by rotating the adjustment plate 512 (around the rotation axis 511), and then the fixing bolt 513 can be screwed into the corresponding fixing groove 514 to lock. After the stationary mold 3 is fixed, the hydraulic rod 8 is started, and its telescopic shaft pushes the lifting plate 9 to slide down along the upright 6, which drives the moving mold 10 to descend. The auxiliary positioning cone 12 at the bottom of the fixing strip 11 on both sides of the moving mold 10 and the auxiliary positioning cone groove 13 of the stationary mold 3 are precisely matched to correct the mold closing deviation. Finally, the precise alignment and fitting of the moving and stationary molds are achieved, and the positioning preparation before die casting is completed.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
