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.

[0024] Please see Figure 1-2 The embodiments of this utility model include:

[0025] A cutting mechanism for plastic parts includes: a cutting frame 1, a cutting platform 2, a guide seat 3, a guide channel 4, an opening 5, a cutting assembly, a lifting platform 6, a lifting guide 7, and a cutting drive mechanism 8.

[0026] The cutting platform is set on the cutting machine frame, and the guide seat is set on the cutting platform. The guide seat is provided with a guide groove with openings at both ends to limit and guide the material belt 18 when it passes through, to prevent the material belt from shifting in the left and right direction or warping or bending in the up and down direction, to improve the flatness of the material belt and facilitate subsequent cutting. The top of the guide seat is provided with an opening that communicates with the guide groove so that the cutting component can extend in to cut.

[0027] In a further preferred embodiment, the guide seat is detachably connected to the cutting platform via fasteners such as screws, allowing the width of the guide channel to be adjusted according to the width and thickness of the material strip, or a guide seat that meets the requirements can be directly replaced.

[0028] Further preferably, the cutting platform can be lifted and mounted on the cutting machine frame to connect with different injection molding or conveying equipment.

[0029] The lifting guide is set on the cutting platform, and the lifting platform is movably connected to the lifting guide. The cutting drive mechanism is set on the top of the cutting frame, and its output end is connected to the lifting platform to drive the lifting platform to move up and down along the lifting guide. The cutting component is set on the lifting platform.

[0030] More preferably, the lifting guide includes a lifting guide rod, a lifting slide rail, etc.

[0031] The cutting assembly includes a cutting protective cover 9, a limiting guide groove 10, a mounting bracket 11, a limiting guide post 12, a reinforcing member 13, a first cutting blade 14, a second cutting blade 15, and a cutting opening 16.
