[0035] Referring to Figures 1-4 The utility model proposes a kind of clamping device for cast aluminium rotor production, for clamping iron core, comprising:

[0036] Frame body 100, including first frame body 110 and second frame body 120, first frame body 110 and second frame body 120 are distributed with interval, and the gap between the two forms sliding path 130;

[0037] Connecting plate 200, it is connected first frame body 110 and second frame body 120, and connecting plate 200 avoids sliding path 130;

[0038] Clamping unit, it includes fixed support block 310, sliding clamping block 320, fixed support block 310 is fixedly connected with second frame body 120, and sliding clamping block 320 is located in sliding path 130, and the clamping block 324 of sliding clamping block 320 is moved along sliding path 130 and has the clamping position of abutting with fixed support block 310 and the blanking position away from fixed support block 310, and sliding clamping block 320 is symmetrically arranged on the two sides of fixed support block 310.

[0039] The scheme provides a clamping device for cast aluminum rotor production, which is mainly used in the process of cast aluminum rotor pressure casting. The clamping device is installed in the movable mold part of the mold closing mold. During pressure casting, the iron core needs to be fixed at the accurate position in the pouring cavity for the pouring of aluminum strip. First, the iron core is placed at the fixed supporting block 310, and the fixed supporting block 310 coarsely positions and supports the iron core. Then, the clamping block 324 gradually approaches the fixed supporting block 310 along the sliding path 130, and the clamping block 324 abuts against the iron core to finely position and strongly support the iron core. Since the position of the fixed supporting block 310 and the clamping block 324 when they are enclosed is fixed, the position of the iron core after being clamped is also determined, which can ensure that the iron core is located at the accurate position in the mold during pouring, ensuring the final pouring effect and improving the accuracy of the clamping position of the iron core in the mold closing mold. In addition, the sliding clamping blocks 320 are symmetrically distributed on both sides of the fixed supporting block 310, and the clamping blocks 324 on both sides move synchronously towards the fixed supporting block 310, synchronously contact the iron core and produce clamping to prevent the iron core position from being offset due to unilateral clamping.

[0040] Optionally, the sliding clamping blocks 320 can be provided with 2n, where n is an integer. In a preferred embodiment, the sliding clamping blocks 320 are provided with two, which are symmetrically arranged on both sides of the fixed supporting block 310. The fixed supporting block 310 is a non-moving member, so when the iron core is placed on the fixed supporting block 310, the fixed supporting block 310 will support the lower area of the iron core. If the iron core is clamped on both sides at this moment, it may cause the iron core to move on the fixed supporting block 310. Therefore, the two sliding clamping blocks 320 are arranged at a certain degree of inclination. When the inclined sliding clamping blocks 320 exert a pressing force on the iron core, the fixed supporting block 310 can generate a supporting force in the opposite direction of the pressing force of the sliding clamping blocks 320, avoiding the position offset of the iron core.

[0041] To further ensure the accurate enclosure of the clamping blocks 324 on both sides, a positioning protrusion 329 is provided on one of the two clamping blocks 324, and a positioning groove 328 is provided on the other. When the positioning protrusion 329 completely extends into the positioning groove 328, the enclosure of the two clamping blocks 324 is completed.

[0042] Specifically, the sliding clamping block 320 includes a track block 321, a sliding block 322, a connecting block 323, a clamping block 324, a coupling 325, and a hydraulic cylinder (not shown). The track block 321 is connected with the connecting plate 200, and one side of each sliding block 322 is slidably connected with a track block 321 to ensure the accuracy of the movement path of the clamping block 324. In addition, the coupling 325 is provided to connect the hydraulic cylinder and the clamping block 324, which can compensate for the alignment error and further improve the movement accuracy of the clamping block 324.

[0043] In addition, since the casting process is high-pressure casting, and more molten aluminum than the required amount is pressed into the casting cavity during the casting process (for example, 50 kg of molten aluminum is cast, more than 50 kg of molten aluminum is pressed into the casting cavity), the remaining molten aluminum needs to be treated, and the high-temperature molten aluminum needs to be prevented from spattering due to high pressure at the gap between the two molds. To solve the above problems, the anti-spatter plate 400 is provided, and the anti-spatter plate 400 has continuous corrugated protrusions. When the molten aluminum flows to the anti-spatter plate 400 and contacts the corrugated protrusions, the flow rate is greatly reduced, so that it is difficult for the molten aluminum to flow through the corrugated protrusions to the outside of the mold.

[0044] Generally, when the molten aluminum flows through the first corrugated protrusion, the flow rate is greatly reduced, so that the overflow hole 500 is provided on the side of the anti-spatter plate 400 close to the fixed support plate, providing a channel for the molten aluminum to overflow, so that the molten aluminum can flow to a specific area.

[0045] In addition, the overflow half-groove 327 is also provided on the clamp block 324, and the two overflow half-grooves 327 are combined to form an overflow groove after the two clamp blocks 324 are enclosed. The excess molten aluminum can flow out through the overflow groove and flow to a specific area for treatment.

[0046] During the molten aluminum overflow process, only when the molten aluminum flows to the edge of the frame body 100, there is a risk of spattering, so the anti-spatter plate 400 is arranged at the edge of the frame body 100, and there is a certain distance between the clamping unit and the anti-spatter plate 400. In order to be able to provide comprehensive protection, the clamping unit and the anti-spatter plate 400 are provided with a link plate 600, and the link plate 600 is provided with a receiving groove, and the receiving groove is also provided with an overflow hole 500. The molten aluminum between the clamping unit and the anti-spatter plate 400 is collected.

[0047] In addition, since the first frame body 110 and the second frame body 120 are independent components, a connecting plate 200 is required to connect and fix them. In addition to the connecting plate 200, a support 700 is also provided to connect the two. Specifically, the two ends of the support 700 are connected with the first frame body 110 and the second frame body 120, respectively. At the same time, the support 700 is also a support component of the hydraulic cylinder.

[0048] In addition to the above functions, the connecting plate 200 also has a thimble plate 210, and the thimble plate 210 is provided with thimble holes 211. The thimble holes 211 are uniformly and spaced apart along the ring direction of the thimble plate 210. After the casting is completed, the thimble passes through the thimble hole 211 to separate the rotor from the mold, which is convenient for the mechanical hand to clamp and unload.

[0049] The frame body 100 is further provided with a buckling groove 140, which is used for limiting the position of the two molds in cooperation with the limiting rod during the closing process of the fixed mold and the movable mold, so as to ensure the accurate buckling of the two molds. In addition, after the mold is closed, the locking block 326 is further arranged to prevent the accidental sliding of the clamping block 324. After the mold is closed, the locking block 326 extends into the locking groove of the opposite mold, so as to lock the clamping block 324, and ensure the fixed position of the clamping block after the mold is closed.

[0050] The above is only an optional embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by the utility model specification and the drawings, or direct / indirect application in other related technical fields under the inventive concept of the utility model is included in the patent protection range of the utility model.
