[0020] The following elaborates on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0021] The present utility model provides a cutting machine for plastic injection products, as Figures 1-5As shown in the figure, the connecting end of the driving mechanism penetrates through the housing 2 and is connected with a blade 5. A control system 3 is arranged at the top of the front end of the housing 2. A control button 7 electrically connected to the driving mechanism is arranged on the top surface of the base 1. A tool rest 8 is arranged on the top surface of the base 1 directly below the blade 5, and the tool rest 8 is flush with the top surface of the base 1.

[0022] The driving mechanism is used to drive the blade 5 to move up and down, and then cooperate with the tool rest 8 to cut the inserted plastic product. During cutting, the redundant edges of the product are manually pushed onto the tool rest 8 by hand so that the edges correspond to the blade 5 above. At this time, pressing the control button 7 with the other hand can start the driving mechanism to drive the blade 5 to move downward until it contacts and cooperates with the tool rest 8 to cut off the edges. This replaces the pure manual cutting method with a small knife or scissors, greatly reducing the working intensity and ensuring the trimming efficiency during long-term labor work.

[0023] Furthermore, guide rails 4 are arranged on both sides of the blade 5 on the top surface of the base 1, and both ends of the blade 5 are placed inside the guide rails 4 and are slidably connected to the guide rails 4. A safety light curtain 6 is fixedly connected to the front end of the guide rail 4, and the installation light curtain is electrically connected to the control system 3.

[0024] Two guide rails 4 are arranged on both sides of the blade 5. When the blade 5 moves up and down, the two guide rails 4 are used for sliding and limiting, ensuring the stability of the blade 5 during movement. At the same time, safety light curtains 6 are respectively arranged in front of the guide rails 4. The safety light curtains 6 are used to monitor the limbs of the staff. When the limbs of the staff enter the range of the safety light curtains 6, at this time, the safety light curtains 6 immediately send signals into the control system 3, and the control system 3 controls the driving mechanism to stop working immediately, greatly improving the safety of the cutting equipment and avoiding some unnecessary dangers during long-term work.

[0025] Furthermore, a blanking groove 9 is opened on the top surface of the base 1 at the back of the tool rest 8. A collection box 10 is arranged at the bottom of the base 1 directly below the blanking groove 9. An inclined surface 91 is arranged in front of the blanking groove 9, and the top of the inclined surface 91 extends to the top end of the back of the tool rest 8 and is flush with the tool rest 8.

[0026] The cut edges smoothly fall from the blanking groove 9 along the inclined surface 91 and finally fall into the collection box 10 for collection, realizing the automatic collection of the edge waste, avoiding the accumulation of waste on the base 1 and affecting the subsequent cutting work, and at the same time ensuring the smoothness of the top surface of the base 1 and improving the aesthetics.

[0027] Further, the driving mechanism includes a cylinder 11 fixedly installed inside the housing 2, a connecting rod fixedly connected to the piston end of the cylinder 11, and a guide rod 13 fixedly installed at the bottom of the other end of the connecting rod 12. Among them, the guide rod 13 is designed to be vertically parallel to the cylinder 11, and the bottom of the guide rod 13 penetrates the housing 2 and is connected to the blade 5. The cylinder 11, the connecting rod 12, and the guide rod 13 form a U-shaped structure. Its driving principle is that the cylinder 11 drives the connecting rod 12 to move up and down, so that the guide rod 13 moves up and down to drive the blade 5 to move up and down.

[0028] Further, the seat includes a bottom plate 101, a column 102, and a top plate 103. The bottom plate 101 is spaced from the top and is supported by four columns 102. The blanking chute 9 is opened on the top plate 103, and the collection box 10 is placed between the bottom plate 101 and the top plate 103.

[0029] The working principle of the present utility model: Place the product to be trimmed on the top surface of the base 1, and then push the product to push the edge of the product onto the blanking chute 8 and correspond to the blade 5 up and down. At this time, press the control button 7 with the other hand to start the cylinder 11. The cylinder 11 works to drive the guide rod 13 to move up and down through the connecting rod 12, so that the blade 5 moves downward until it contacts and cooperates with the tool rest 8 to cut off the edge. Subsequently, release the control button 7, and the cylinder 11 drives the blade 5 to reset. The cut edge smoothly falls from the blanking chute 9 along the inclined surface 91 and finally falls into the collection box 10 for collection;

[0030] During the cutting process, when the staff's limb enters the range of the safety grating 6, at this time, the safety grating immediately sends a signal to the control system 3, and the control system 3 controls the driving mechanism to stop working immediately, greatly improving the safety of the cutting equipment and avoiding some unnecessary dangers during long-term work.

[0031] The following points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, and can also be the communication inside two components. It can be directly connected. "Up", "down", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the described object changes, the relative position relationship may change;

[0032] The above is only the preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the content disclosed by the present utility model should be included in the protection scope recorded in the claims.
