[0008] The top surface of the side plate at the left side of the vibrating feeding disc is formed with a downward-extending finished product outlet. The bottom surface of the finished product outlet has downward-extending grooves on the left and right sides. The middle of the two guide troughs is inserted into the corresponding grooves, and their outer walls are welded and fixed to the inner walls of the corresponding grooves. The outer ends of the two guide troughs extend out of the outer wall of the side plate at the left side of the vibrating feeding disc, and the inner ends of the two guide troughs are located in the outermost discharge channel of the disc.

[0015] Figure 3 This is a partial structural diagram of the combination of injection molded products and waste materials;

[0016] Figure 4 yes Figure 3 A schematic diagram of the local structure from a different angle. Detailed implementation method:

[0017] For example, see below. Figures 1 to 4As shown, an automatic separation device for injection molded products and sprue includes a base 10. A vibrating feeding plate 20 is fixed in the middle of the top surface of the top plate of the base 10. A receiving and fixing support frame 30 is fixed in the top surface of the top plate of the base 10 at the right side of the vibrating feeding plate 20. A receiving hopper 40 is fixed in the upper part of the receiving and fixing support frame 30. A horizontal discharge guide trough 50 extending to the left is provided below the bottom discharge port of the receiving hopper 40. The discharge port at the left end of the horizontal discharge guide trough 50 faces the upper part of the material discharge point in the middle of the top plate of the vibrating feeding plate 20, and the upper part of the right end of the horizontal discharge guide trough 50 faces the bottom discharge port of the receiving hopper 40.

[0018] The outer wall of the vibrating feeding plate 20 has a downwardly extending waste discharge port 21 formed on the top surface of the middle part of the outer wall of the vibrating feeding plate 20. A waste discharge trough 22 extending outward and downward is fixed in the middle of the outer wall of the vibrating feeding plate 20. The inner end of the waste discharge trough 22 is connected to the waste discharge port 21.

[0019] The top surface of the side plate at the left part of the vibrating feeding plate 20 is formed with a downwardly extending finished product outlet 23. The left and right sides of the bottom surface of the finished product outlet 23 are formed with downwardly extending grooves. The middle part of the two guide troughs 24 is inserted into the corresponding grooves, and their outer side walls are welded and fixed to the inner side walls of the corresponding grooves. The outer ends of the two guide troughs 24 extend out of the outer wall surface of the side plate at the left part of the vibrating feeding plate 20, and the inner ends of the two guide troughs 24 are in the outermost discharge channel of the plate.

[0020] In this embodiment, the distance between the left and right side walls of the waste outlet 21 is less than the outer diameter of the injection molded product 100, and the distance between the left and right side walls of the waste outlet 21 is greater than the maximum width or maximum length of the waste 101 in the middle of the injection molded product 100. The distance between the left and right sides of the finished product outlet 23 is greater than the outer diameter of the injection molded product 100. The injection molded product 100 is a ring body, and its outer diameter is greater than the distance between the left and right side walls of the waste outlet 21. Its waste 101 includes a vertical central axis, and three transverse rods are formed on the outer side wall of the middle part of the vertical central axis. All transverse rods are evenly distributed on the outer side wall of the vertical central axis with the vertical central axis as the center. During casting, the outer ends of the three transverse rods of the waste 101 are formed on the inner side wall of the injection molded product 100.

[0021] Furthermore, a connecting frame is fixed on the top surface of the top plate of the base 10 on the left side of the vibrating feeding plate 20. A left discharge trough 60 extending diagonally downward from right to left is fixed on the top of the connecting frame. The outer ends of the two guide troughs 24 are located above the right end of the left discharge trough 60 and correspond to the left discharge trough 60.

[0022] Furthermore, the receiving and fixing support frame 30 includes two vertical bending members 31, one at the front and one at the back. Above the top bending plate of each of the two vertical bending members 31, an upper bending plate is fixed to the bottom surface of the front and rear of the receiving hopper 40. Multiple rubber elastic blocks 1 are clamped between the upper bending plate and the top bending plate. A vertical through hole is formed in the center of each rubber elastic block 1. A connecting shaft is inserted into the vertical through hole. The top and bottom of the connecting shaft are inserted into the corresponding through holes of the corresponding upper bending plate or top bending plate. The bottom threaded portion of the connecting shaft extends out of the bottom surface of the top bending plate and is fixed with a first fixing nut. The top surface of the first fixing nut presses against the bottom surface of the corresponding top bending plate. The top threaded portion of the connecting shaft extends out of the top surface of the upper bending plate and is threaded with a second fixing nut. The bottom surface of the second fixing nut presses against the top surface of the corresponding upper bending plate. (See attached diagram) Figure 2 The first and second fixing nuts are shown in the image; the rest are omitted and not shown.

[0023] This structure allows for shock absorption when material falls from the receiving hopper 40 via the rubber elastic block 1.

[0024] Furthermore, an intermediate support frame 11 is fixed on the top surface of the top plate of the base 10 between the two vertical bending members 31. A linear vibrating feeder 12 is fixed on the top plate of the intermediate support frame 11, and a horizontal discharge guide groove 50 is fixed on the top plate of the linear vibrating feeder 12. A rectangular extension sleeve is formed at the bottom discharge port of the receiving hopper 40, which is inserted into the horizontal discharge guide groove 50. The linear vibrating feeder 12 and the vibrating loading plate 20 are both existing conventional components and will not be described in detail here.

[0025] In this embodiment, the feeding box containing the injection-molded product 100 and waste material 101 is tilted, allowing the injection-molded product 100 and waste material 101 to enter the receiving hopper 40. Then, they enter the horizontal discharge guide trough 50. As the linear vibrating feeder 12 vibrates, the injection-molded product 100 and waste material 101 in the horizontal discharge guide trough 50 enter the discharge point in the middle of the top of the vibrating feeding plate 20. As the vibrating feeding plate 20 operates, the injection-molded product 100 and waste material 101 are conveyed along the spiral discharge channel of the vibrating feeding plate 20. All the way to the outermost discharge channel, the waste discharge port 21 blocks the injection molded product 100, while the waste 101 can come out from the waste discharge port 21 and be discharged along the waste discharge trough 22 (a waste box can be placed below its outer end for receiving the waste, which is a standard setting and is not shown in the attached figure). The injection molded product 100 comes out from the finished product discharge port 23 along the two guide troughs 24 and enters the left discharge trough 60, and falls along the left discharge trough 60 into the finished product receiving box placed below its discharge port (the finished product receiving box is a standard setting and is not shown in the attached figure).

[0026] When waste material 101 does not exit from waste material outlet 21 but enters finished product outlet 23, its vertical central axis will be between the two guide troughs 24, and it will not be able to exit from finished product outlet 23, ensuring that the finished product outlet 23 only produces injection molded products 100. When waste material 101 is stuck in the two guide troughs 24, it needs to be manually removed.

[0027] This embodiment can separate injection molded product 100 and waste material 101, greatly reducing manual labor, improving sorting efficiency, and achieving good results.
