Plastic flooring has been used in the construction industry for a long time, and its form, color and utilization are also very rich and extensive. Usually, the plastic floor is obtained by hot pressing the plastic mixture, and then punched according to the required size, so as to obtain a brick-shaped plastic floor with an appropriate size. Generally, the punching method for plastic flooring is to place the large-sized plastic flooring master piece on a whole piece of polypropylene (PP, Polypropylene) plastic chopping board, and then use the knife die to directly punch and cut the plastic flooring master piece. , to form M×N (M, N is a positive integer) matrix multiplier number of plastic floors. However, under repeated punching, the surface of the PP plastic cutting board is prone to damage or serious dents. When the PP plastic cutting board is old and damaged, the entire PP plastic cutting board must be discarded, resulting in increased cost.

Please refer to FIG. 1 and FIG. 2. FIG. 1 is an exploded perspective view of a conventional cutting board and die for punching plastic flooring.

Sheet 20 is punched into multiple plastic floors of appropriate size. As shown in FIG. 2 , one plastic floor mother sheet can be punched into four plastic floors. The chopping board 100 has a surface 101 for placing the plastic floor master piece 20 . The surface 101 refers to the surface of the chopping board 100 in contact with the cutting boards 11 and 12 . The entire piece of cutting board 100 is a flat plate directly extruded or injection-molded from polypropylene (PP, Polypropylene) plastic material, so once the cutting board 100 is damaged or dented, it cannot be repaired, so it is a consumable used in the process . Please refer to FIG. 1 and FIG. 2 , during the punching process, the knife die 10 will press down on the chopping board 100 , so that the knife boards 11 and 12 cut through the vinyl flooring mother sheet 20 . When the cutting boards 11 and 12 are cutting through the plastic flooring mother sheet 20 , the cutting boards 11 and 12 will also cut into the cutting board 100 a little to form cutting dents. Under repeated punching, the cutting dents formed on the surface 101 of the cutting board 100 will become more and more obvious, and even cause the surface of the cutting board 100 to be uneven, and another whole cutting board must be replaced, resulting in an increase in cost.
