[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] A machine for cutting excess material of injection molded fast food boxes, such as Figure 1-Figure 3 As shown, it includes a support table 1, an injection molding block 11, a mold 12, a cutting knife 2, a cylinder 21, a motor 22 and a screw rod 23. The injection molding block 11 is installed on the support table 1. The mold 12 is slidably connected to the support table 1. The melted plastic flows out of the injection molding block 11 and is formed between the injection molding block 11 and the mold 12. A guide rod is provided inside the support table 1, and the mold 12 slides on the guide rod. A cylinder 21 is installed on the right side of the support table 1. The output end of the cylinder 21 is connected to the cutting knife 2. The size of the cutting knife 2 is the size of a standard fast food box. The cutting knife 2 is used to cut off the residual material at the corners of the plastic model. A motor 22 is installed on the left side of the support table 1. The output shaft of the motor 22 is connected to the screw rod 23, and the mold 12 slides on the screw rod 23.

[0023] First, the injection block 11 is started to move downward to the mold 12, and then the melted plastic flows out of the injection block 11 and is formed between the injection block 11 and the mold 12. At this time, excess residue may overflow from the corners. In order to remove the excess residue, after the injection block 11 moves upward, the motor 22 is started to drive the screw rod 23 to rotate. The rotation of the screw rod 23 can move the mold 12 to the right. When the mold 12 moves to the rightmost end, the cylinder 21 is started to drive the cutting knife 2 to move downward. The cutting knife 2 can cut off the excess residue, and then the cut plastic model can be taken out.

[0024] On the basis of Example 1, Figure 3 As shown, it also includes a cleaning brush 3, a pressure rod 31, a rotating shaft 32, a connecting rod 33 and a guide rod 34. The pressure rod 31 is fixedly connected to the rear side of the injection block 11, and the bottom of the pressure rod 31 is rotatably connected to the rotating shaft 32. The rotating shaft 32 is fixedly connected to the connecting rod 33, and the connecting rod 33 is rotatably connected to the cleaning brush 3. The cleaning brush 3 is a soft brush. The cleaning brush 3 can brush along the surface of the mold 12 to clean the residual material on the mold 12. A guide rod 34 is provided on the left part of the support table 1, and the cleaning brush 3 slides on the guide rod 34. The guide rod 34 is used to guide the cleaning brush 3.

[0025] After taking out the plastic model, some sticky residues may remain on the mold 12, and the presence of the residues will affect the next round of injection molding. To avoid this situation, when the injection molding block 11 moves downward, the injection molding block 11 will drive the pressure rod 31 to move downward, and the pressure rod 31 can squeeze the connecting rod 33. At this time, the rotating shaft 32 rotates, and the connecting rod 33 pushes the cleaning brush 3 forward. The cleaning brush 3 slides forward along the guide rod 34, and the cleaning brush 3 can brush off the residues on the mold 12. When the injection molding block 11 moves down to the bottom, the cleaning brush 3 just slides to the front end, thereby It will not affect the normal operation of the injection molding block 11. After the plastic model is initially cooled on the mold 12, the injection molding block 11 moves upward, the pressure rod 31 pulls the connecting rod 33, and the connecting rod 33 begins to pull the cleaning brush 3 backward. When the injection molding block 11 just rises to a certain distance above the mold 12, the injection molding block 11 is suspended from rising. At this time, the cleaning brush 3 is still located in front of the mold 12. Then, the motor 22 is started to drive the mold 12 to move to the right. When the mold 12 moves to the rightmost end, the injection molding block 11 is started to move upward again. At this time, the cleaning brush 3 moves backward and resets.

[0026] like Figure 5 and Figure 6 As shown, it also includes a hot air box 4, a connecting rod 41, a pressing button 42 and a compression spring 43. The hot air box 4 is installed on the rear side of the support platform 1. The hot air blown out by the hot air box 4 can make the residual material on the mold 12 easier to be cleaned by the cleaning brush 3. The rear side of the support platform 1 is connected with a connecting rod 41, the connecting rod 41 is connected to the hot air box 4, and a pressing button 42 is slidably connected to the side away from the hot air box 4. The pressing button 42 is pressed by the pressing rod 31 under normal conditions. The connecting rod 41 is a hollow structure. An electric wire is arranged in the connecting rod 41. The two ends of the electric wire are respectively connected to the hot air box 4 and the pressing button 42. A compression spring 43 is arranged between the pressing button 42 and the connecting rod 41. The two ends of the compression spring 43 are respectively connected to the connecting rod 41 and the pressing button 42. The pressing button 42 can control the opening and closing of the hot air box 4.

[0027] Some of the residual materials on the mold 12 may be tightly adhered, and it may be difficult to completely remove the residual materials only by the cleaning brush 3. In order to avoid this situation, when the injection block 11 moves downward, the pressure rod 31 moves downward. At this time, the pressure rod 31 disengages from the pressure button 42, and the compression spring 43 is reset from the compressed state, so that the pressure button 42 is pushed downward, thereby starting the hot air box 4. The hot air box 4 can blow hot air to the mold 12, thereby assisting the cleaning brush 3 to clean the residual materials.

[0028] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments may be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
