[0028] Working principle: In the existing hole-punching device for mold production, debris will be generated during the hole-punching process. In order to avoid dust flying, the debris often needs to be collected and cleaned. During the debris cleaning and collection process, the debris sucked into the collection box is easy to cause the filter to be blocked, resulting in poor air flow in the cavity, thereby affecting the effect of debris collection and cleaning; therefore, in view of the above problems, a hole-punching device for mold production is proposed; when cleaning the debris generated during the hole-punching process, the second motor 18 is operated to make the rotating shaft 19 drive the fan 20 and the scraper 21 The fan 20 rotates at a high speed, so that the debris generated in the hole-opening process is sucked into the dust box 15 through the dust suction pipe 16. At the same time, the scraper 21 rotates to scrape off the debris adsorbed on the surface of the filter plate 17. The scraped debris finally falls into the collection bag 23, so that the debris generated in the hole-opening process can be cleaned and collected, and the filter plate 17 can also be scraped and cleaned, so as to avoid the phenomenon that the filter plate 17 is blocked by the debris, thereby ensuring the smooth flow of air in the cavity, thereby ensuring the effect of subsequent debris collection and cleaning;

Through the cooperation of the movable rod 30 and the spring 32, the pressing plate 31 can press the mold, so that the mold can be pressed and fixed to avoid the displacement of the mold during the hole drilling process. During the hole drilling process, the first motor 7 is operated to make the screw drive the I-shaped slide block 8 to move along the slide groove 6, so that the cavity drill bit 13 can move horizontally, and move along the T-shaped slide rail 2 through the sliding sleeve 3, so that the support frame 5 drives the cavity drill bit 13 to move longitudinally, so that the hole drilling operation can be performed at different positions of the mold.
