[0025] Reference Figures 1 to 4The injection molded part runner separation mechanism of the utility model embodiment includes a bracket 100, a three-coordinate moving mechanism 200 and a clamp 300. The bracket 100 is rotatably connected to a rotating arm 110, and the rotating arm 110 can pivot on a vertical plane; the three-coordinate moving mechanism 200 and the ends of the rotating arm 110 are fixedly connected; the clamp 300 includes a main body 310, a driving rod 320 and two clamping claws 330, the lower end of the main body 310 is provided with a rotating groove 311, the upper end of the main body 310 is provided with a sliding groove 312, and the sliding groove 313 is provided on the upper end of the main body 310. The groove 312 is arranged along the vertical direction, the driving rod 320 is inserted into the sliding groove 312 and extends into the rotating groove 311, the driving rod 320 and the sliding groove 312 are slidably connected, one end of the clamping jaw 330 and the end of the driving rod 320 extending into the rotating groove 311 are rotatably connected, and the other end is provided with a clamping portion 331, and the middle part of the clamping jaw 330 is rotatably connected to the rotating groove 311; wherein, the clamp 300 is connected to the three-coordinate moving mechanism 200, and the three-coordinate moving mechanism 200 drives the clamp 300 to move in space.

[0026] In the specific use process of this embodiment, the bracket 100 is arranged between two adjacent injection molding machines. After one of the injection molding machines completes the injection molding process, the three-coordinate moving mechanism 200 is used to drive the clamp 300 to extend between the upper mold and the lower mold of the injection mold, and the clamp 300 is attached to the molding surface. The runner is clamped out by the clamp 300, and the clamp 300 is returned to the original position along the original route, and the runner is abandoned. At this time, the other injection molding machine is performing the injection molding process; after the other injection molding machine completes the work, the previous injection molding machine restarts the injection molding work, and at the same time, the three-coordinate moving mechanism 200 is used to drive the clamp 300. 0 extends between the upper mold and the lower mold of the injection mold that has completed the injection molding process at this time, and makes the clamp 300 fit the molding surface, uses the clamp 300 to clamp out the runner, and returns the clamp 300 to the original position along the original route, and abandons the runner; specifically, in the position where the three-coordinate moving mechanism 200 cannot be directly moved to, the clamp 300 can be extended obliquely into the injection molding machine by rotating the rotating arm, so as to adapt to the injection molding machine with large volume and wide width. Accordingly, two or more injection molding machines can be separated by the runner separation mechanism of the injection molded part of the present embodiment, which effectively improves the use efficiency and reduces the production cost.

[0027] In summary, by utilizing the three-coordinate moving mechanism 200 and cooperating with the rotating arm 110 on the bracket 100 , the clamp 300 can be driven to move to any position to take out or discard the flow channel, thereby improving automation.

[0028] It should be mentioned that the clamping jaw 330 rotates to make the two clamping parts 331 approach or move away from each other to clamp or discard the flow channel, and specifically, the clamping parts 331 are arranged on opposite sides of the clamping jaw 330. The clamping parts 331 clamp the main flow channel by directly contacting the flow channel, and further, in order to improve the clamping stability, the clamping part 331 is composed of a plurality of clamping teeth to increase the friction between the clamping part 331 and the main flow channel and improve the clamping stability.

[0029] As can be seen from the above, the driving rod 320 synchronously drives the clamping jaw 330 to rotate by lifting and lowering to clamp the flow channel, wherein the driving rod 320 is a rack rod, and the main body 310 is built with a mounting groove 313, and the mounting groove 313 is rotatably connected to the driving gear 321, and the driving gear 321 is meshed with the rack rod. By utilizing the meshing between the driving gear 321 and the rack rod, the rotation of the driving gear 321 can drive the rack rod to rise and fall. Furthermore, the outer side of the main body 310 is fixedly connected to a driving motor, and the output shaft of the driving motor is fixedly connected to the center of the driving gear 321.

[0030] It should be mentioned that the three-coordinate moving mechanism 200 includes an X-axis rail 210, a Y-axis rail 220, a Z-axis rail 230 and a moving part 240. The X-axis rail 210 is fixedly connected to the end of the rotating arm 110, the Y-axis rail 220 is slidably connected to the X-axis rail 210 and can slide along the X-axis rail 210, the Z-axis rail 230 is slidably connected to the Y-axis rail 220 and can slide along the Y-axis rail 220, the moving part 240 is slidably connected to the Z-axis rail 230 and can slide along the Z-axis rail 230, and the main body 310 is connected to the moving part 240. The Y-axis rail 220, the Z-axis rail 230 and the moving part 240 move on the X-axis rail 210, the Y-axis rail 220 and the Z-axis rail 230 respectively, so that the moving part 240 can reach any position in the space covered by the length of the X-axis rail 210, the Y-axis rail 220 and the Z-axis rail 230, and combined with the rotation of the rotating arm, the clamp 300 can reach a farther position.

[0031] It should be mentioned that the movable member 240 is in the shape of an elongated strip and is parallel to the Z-axis track 230. The end of the main body 310 away from the clamp 330 is rotatably connected to the end of the movable member 240 so that the main body 310 can pivot around the length direction of the movable member 240, so that the direction of the two clamps 330 can be changed, which is convenient for discarding the flow channel.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
