[0002] After the injection molded product body and sprue are opened, they need to be demolded and removed, and then the mold is closed to carry out the subsequent injection molding production of injection molded products.

[0003] During injection molding, the molded part and the sprue are connected. They can be separated during mold opening using a demolding mechanism, and then removed and sorted. To improve production efficiency and operational safety, a robotic arm can be used to grip and sort the molded parts and sprues. However, in some cases, the separation of the molded part and the sprue is incomplete, with occasional remnants preventing them from falling separately during sorting, leading to mixed-assembly issues. This requires improvement. Utility Model Content

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please see Figures 1-2 The embodiments of this utility model include:

[0019] like Figure 1 The jig shown is for separating the sprue from the injection molded product body. It includes a mounting plate 1 and a clamping and separating assembly. The clamping and separating assembly is disposed on the mounting plate 1. In this embodiment, the mounting plate 1 is a rectangular plate. There are two sets of clamping and separating assemblies, which are spaced apart along the length of the mounting plate 1. This allows for the simultaneous gripping and separation of two sets of sprues from the injection molded product body.

[0020] A C-shaped connecting plate 11 is provided on the back of the mounting plate 1. The mounting plate 1 is mounted on the robotic arm via the C-shaped connecting plate 11. It is moved into the injection mold and the sprue and the injection molded product body are gripped by the clamping and separating component, and the sprue and the injection molded product body are removed from the injection mold. The C-shaped connecting plate 11 and the mounting plate 1 can be fixed with screws, and the structure is sturdy.

[0021] The clamping and separating assembly includes a first pneumatic finger 5, a second pneumatic finger 2, a third pneumatic finger 8, and a lifting drive mechanism. The lifting drive mechanism is located on the back of the mounting plate 1 and does not occupy the space on the front of the mounting plate 1.

[0022] The first pneumatic finger 5 is mounted on the lifting drive mechanism and points vertically toward the mounting plate 1. In this embodiment, the lifting drive mechanism includes a telescopic cylinder 7 and a connecting member 6. The telescopic cylinder 7 is vertically mounted on the back of the mounting plate 1, and the connecting member 6 is located between the end of the telescopic cylinder 7 and the side of the first pneumatic finger 5. By extending and retracting the telescopic cylinder 7, the connecting member 6 and the first pneumatic finger 5 are driven to move linearly along the direction perpendicular to the mounting plate 1.

[0023] In this embodiment, the connector 6 is an L-shaped bent plate, which can be fixed to the telescopic cylinder 7 and the first pneumatic finger 5 with screws, making disassembly and assembly convenient. Figure 2 As shown, a clearance groove 12 corresponding to the first pneumatic finger 5 is provided on the mounting plate 1. The clearance groove 12 can avoid affecting the movement of the first pneumatic finger 5 in the direction perpendicular to the mounting plate 1.

[0024] A first gripper 4 extending to the front of the mounting plate 1 is provided at the end of the first pneumatic finger 5, which can clamp the sprue 10. The second pneumatic finger 2 and the third pneumatic finger 8 are provided on the mounting plate 1 and located on both sides of the first gripper 4. The ends of the second pneumatic finger 2 and the third pneumatic finger 8 are respectively provided with second grippers 3 corresponding to the first gripper 4, which can clamp the injection molded product body 9 located at both ends of the sprue 10.

[0025] After the sprue 10 and the injection molded product body 9 are clamped by the first gripper 4 and the second gripper 3 respectively, the first pneumatic finger 5 is driven to extend and retract by the lifting drive mechanism to ensure the complete separation of the sprue 10 and the injection molded product body 9, avoiding the problem of tangled threads. Finally, they are moved to the top of the finished product frame and the sprue frame in sequence to drop the injection molded product body 9 and the sprue 10 separately, avoiding the problem of mixed assembly.

[0026] like Figure 1 As shown, the second pneumatic finger 2 is located on the side of the mounting plate away from the other set of clamping and separating components, and the third pneumatic finger 8 is located on the front or back of the mounting plate 1. One of the third pneumatic fingers of the two sets of clamping and separating components is located on the front of the mounting plate 1, and the other third pneumatic finger is located on the back of the mounting plate 1, which improves space utilization and makes the structure compact.

[0027] In summary, the sprue and injection molded product body separation fixture disclosed in this utility model can separately clamp the sprue and injection molded product body, ensuring complete separation of the sprue and injection molded product body and separate unloading.
