Technical Field

[0001] This utility model relates to the field of aluminum die casting processing technology, specifically to an aluminum die casting gate separation device. Background Technology

[0002] The gate separation structure for aluminum die castings is a key part of the die casting mold design. Its purpose is to efficiently and stably separate the gate from the casting after die casting is completed.

[0003] Chinese Patent No. CN211464780U discloses a fully automatic zinc die-casting gate separator. The separator uses a hook to pick up the die-casting material head from the stripper plate and transfer it to a conveyor belt. The hooked material head is then transported to a designated location. A feeding hook then picks up the material head from the designated location and transfers it to a rotating platform. The rotating platform rotates, and a flipping component senses and picks up the material, transferring it to a working position. The clamping and flipping mechanism then places the material head onto a placement platform. An ultrasonic device is activated to separate the product and the material head. The product falls freely into a placement box, and the material head is automatically returned to the furnace via a return conveyor belt. This method allows for the orderly placement of products and material heads, reduces costs, and improves production efficiency.

[0004] In actual use, the gate separation device of the above-mentioned patent cannot guarantee the accuracy of the gate position by using a material-picking hook, which affects the separation effect. Utility Model Content

[0025] Hydraulic cylinder 2 is installed on one side of base 1. Hydraulic cylinder 2 is fixed to the upper end of fixed frame 101 and connected to fixed frame 101 and base 1 by fixing bolts. A push rod 201 is installed at one end of hydraulic cylinder 2. One end of push rod 201 is fixedly connected to die-cast plate 3, and the lower end of die-cast plate 3 is slidably connected to fixed frame 101. The position of saw head 302 moves with die-cast plate 3 to perform linear displacement punching, avoiding the problem of other drive structures causing cumbersome structure and affecting actual punching operation.

[0026] In fact, a reinforcing frame 301 is welded to the front end of the die-casting plate 3. The reinforcing frame 301 is welded to the sawing head 302. The inner cutting surface of the sawing head 302 is set as a bevel structure. The cutting position of the sawing head 302 corresponds to the position of the gate part 401. During the die-casting process, the hydraulic cylinder 2 drives the push rod 201 to extend and push the die-casting plate 3 to squeeze and fix the mold 4. During the pushing process, the die-casting plate 3 drives the reinforcing frame 301 and the sawing head 302 to punch the upper end of the gate part 401, so that the material head at the upper end of the gate part 401 is cut off.

[0027] In addition, the fixed mold 4 has an integrally formed aluminum die-casting groove 402 inside, which is connected to the gate part 401. The front end of the fixed mold 4 is fixedly installed with a limiting support plate 403, and the die-casting plate 3 is embedded in the outside of the limiting support plate 403 and abuts against the fixed mold 4.

[0028] Specifically, the aluminum die-casting gate separation device performs separation work through dual processing of saw head 302 and cutting head 502. During the die-casting process, the hydraulic cylinder 2 drives the push rod 201 to extend and push the die-casting plate 3 to squeeze and fix the mold 4. During the pushing process, the die-casting plate 3 drives the reinforcing frame 301 and saw head 302 to punch the upper end of the gate part 401, so that the material head at the upper end of the gate part 401 is cut off. The position of saw head 302 moves with the die-casting plate 3 to perform linear displacement punching, avoiding the problem of other driving structures causing cumbersome structure and affecting the actual punching operation.

[0029] Example 2:
