The post-injection molding cutting device for plastic products according to claim 5, wherein a pair of U-shaped material storage frames (7) are fixedly connected to the machine table (1), a material storage station is formed between the two material storage frames (7), the material discharge station is arranged below the cutting assembly (2), and the cut plastic plates automatically fall and stack on the material storage station.
7. A post injection molding cutting method for plastic products using a post injection molding cutting apparatus for plastic products according to claim 6, comprising the steps of:
firstly, placing a plastic plate to be cut on a cutting table (6), and pressing the plastic plate by a pressing roller (604); the pushing cylinder (602) pushes the plastic plate to move towards the cutting assembly (2), and one side of the plastic plate is exposed out of the side of the cutting table (6) for a designated length;
step two, the driving mechanism (4) drives the cutting assembly (2) to move, and the cutting assembly (2) moves from one end of the plastic plate to the other end, so that the cutting of the plastic plate is completed; in the cutting process, a section of the cut plastic plate is bent downwards under the guiding action of a first guide wheel (309) and a second guide wheel (310), and moves between two polishing wheels (302), and a polishing motor (303) drives the two polishing wheels (302) to rotate so as to polish two sides of the cut plastic plate;
step three, after finishing one-time cutting and polishing of the plastic plate, the driving mechanism (4) drives the cutting assembly (2) to move back to the original position, and the pushing cylinder (602) pushes the plastic plate to move forwards for a designated length continuously, and then the plastic plate is cut next time;
and step four, the cut plastic plates are well placed in a storage station, stacked and placed in a discharge station, and are taken away manually or mechanically.
