[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a tool for automatically cutting off the material opening of an injection molded part, comprising:

[0021] Bracket 1;

[0022] Cutting assembly; the cutting assembly includes a rotating column 6 that can rotate on the bracket 1 at a fixed angle, a driving box 3 is installed on the bracket 1, a motor 4 is installed on the driving box 3, the rotating column 6 passes through the driving box 3 and is rotatably connected thereto, a direction-changing member connecting the motor 4 and the rotating column 6 is installed in the driving box 3, an encoder 5 is installed on the direction-changing member, wherein the encoder 5 is connected to a corresponding controller, wherein the encoder 5 is explained: the encoder 5 converts angular displacement or linear displacement into an electrical signal, the former is called a code disk, and the latter is called a yardstick, and the encoder can be divided into contact and non-contact types according to the reading method; according to the working principle, the encoder can be divided into incremental and absolute types, the incremental encoder converts the displacement into a periodic electrical signal, and then converts the electrical signal into a counting pulse, and the number of pulses is used to represent the size of the displacement, the encoder 5 is a prior art, each position of the absolute encoder corresponds to a certain digital code, so its indication is only related to the starting and ending positions of the measurement, but not to the intermediate process of the measurement, the encoder 5 is a prior art;

[0023] The direction-changing member includes a worm that rotates in the drive box 3 and is fixed to the output end of the motor 4. A worm wheel is fixed on the rotating column 6. The worm and the worm wheel are meshed. The encoder 5 is fixedly connected to the worm. Further explanation: the motor 4 drives the worm and the worm wheel to rotate, thereby realizing the rotation of the rotating column 6. The number of circles or angular displacement of the worm can be known through the encoder 5, so that the rotation angle of the rotating column 6 can be known. For example, in the utility model, the discharge plate 7 is a regular octagon and has two cutters 14, so the rotating column 6 stops after rotating 90°, thereby realizing the rotation of the rotating column 6 at a fixed angle;

[0024] A coaxial discharge plate 7 is fixed on the rotating column 6, and a plurality of placement grooves 8 are provided on the outer wall of the discharge plate 7. The injection molded parts are placed in the placement grooves 8. The shapes of the placement grooves 8 and the discharge plate 7 can be selected according to the shapes of the injection molded parts, which is not shown in the figure; at this time, the injection molded parts are against the inner walls of the placement grooves 8 and the outer walls are flush with the outer walls of the discharge plate 7. A material taking groove 9 connected to the placement grooves 8 is penetrated at the upper end of the discharge plate 7, and the injection molded parts can be conveniently taken out through the material taking groove 9;

[0025] An electric push rod 2 is fixed on the bracket 1, and a V-shaped plate 11 is fixed on the output end of the electric push rod 2. The discharge plate 7 is a regular polygonal shape. The V-shaped plate 11 is matched with the outer wall of the discharge plate 7. When the V-shaped plate 11 moves down and faces the discharge plate 7, the V-shaped plate 11 and the outer wall of the discharge plate 7 slide against each other; an inclined surface 12 is provided at the bottom of the V-shaped plate 11. Due to the rotation of the discharge plate 7, the injection molded part is offset outward in the placement groove 8. The electric push rod 2 drives the V-shaped plate 11 to move down, and the inclined surface 12 contacts the injection molded part. As the V-shaped plate 11 moves down, the injection molded part can be limited under the limit of the V-shaped plate 11, so that it can be stably stuck in the placement groove 8, thereby ensuring the quality of cutting;

[0026] Two knife grooves 13 are provided on the V-shaped plate 11, and a cutter 14 is installed in the knife groove 13. Since the injection molded part is limited by the V-shaped plate 11, as the V-shaped plate 11 continues to move downward, the cutter 14 can cut the material mouth of the injection molded part. When working, the staff stands outside and away from the cutter 14, which is safe. In the process of cutting, the staff can place and remove the injection molded part without affecting the cutting work, which can improve the work efficiency.

[0027] A collection box 10 is placed on the bracket 1 below the V-shaped plate 11, and the material cut off by the cutter 14 can be collected through the collection box 10 for recycling.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
