A support platform is fixedly mounted on the top of the two connecting plates. A movable box is fixedly installed on the top of the support platform. A drive cylinder is connected through the interior of the movable box. A limit block is fixedly connected to the bottom of the drive cylinder. A push plate is fixedly connected to the bottom of the limit block. Four connecting columns are fixedly connected to the bottom of the push plate. A fixing block is fixedly connected to the bottom of each connecting column. A die head is fixedly mounted at the bottom of the fixing block. A limit telescopic rod is fixedly mounted at the bottom of the push plate. A hot press fixing plate is fixedly connected to the bottom of the limit telescopic rod. The inner cavity of the hot press fixing plate has a first through hole adapted to the die head. The inner cavity of the base plate has a second through hole adapted to the die head. A sliding sleeve is provided through the inner cavity of the support platform. A buffer sliding rod is movably connected to the inner cavity of the sliding sleeve. Both ends of the buffer sliding rod are through... Extending to the outside of the sliding sleeve, the bottom of the buffer slide rod is fixedly connected to the top of the push plate. The die head is equipped with a heating structure inside. During drilling, the material is conveyed to the bottom plate, and then the drive cylinder is activated. The drive cylinder moves downward, causing the limit block to move downward. The limit block moves downward, causing the push plate to move downward. The push plate moves downward, causing the connecting column and the limit telescopic rod to move downward. The connecting column and the limit telescopic rod move downward, causing the fixing block and the hot-pressing fixing plate to move downward. At this time, the hot-pressing fixing plate is in close contact with the bottom plate to limit the material. Then, the fixing block moves downward, causing the die head to move downward, so that the die head passes through the first through hole and the second through hole. At the same time, with the cooperation of the heating structure inside the die head, the material can be hot-pressed, cut, and drilled. The edges of the holes formed after the material is melted at high temperature are smooth, reducing burrs and improving the appearance quality of the handle holes. At the same time, the hot-pressing drilling process is stable, the handle hole diameter is consistent, ensuring processing accuracy and improving product quality.

[0006] This utility model discloses a hot press punching machine for cutting and heat-sealing double-layer handle holes. Support blocks are fixedly installed at the four corners of the bottom of the base plate. A movable shaft mounting seat is fixedly connected to the bottom of each support block. A movable shaft is fixedly installed inside the movable shaft mounting seat. A limit rod is connected through the inner cavity of the movable shaft. Limit plates are fixedly connected to both ends of the limit rod. Fastening mounting plates are fixedly installed on the outer sides of the two limit plates. A fastening adjustment rod is connected through the two fastening mounting plates.

[0012] 1. In this invention, during the punching process, the material is conveyed to the bottom plate, and then the drive cylinder is activated. The drive cylinder moves downward, causing the limiting block to move downward, which in turn causes the push plate to move downward, which in turn causes the connecting column and the limiting telescopic rod to move downward, which in turn causes the fixing block and the hot-pressing fixing plate to move downward. At this time, the hot-pressing fixing plate is in close contact with the bottom plate to limit the material. Then, the fixing block moves downward, causing the die head to move downward, allowing the die head to pass through the first and second through holes. Simultaneously, with the cooperation of the heating structure inside the die head, the material can be hot-pressed, cut, and punched. The edges of the holes formed after the material is melted at high temperature are smooth, reducing burrs and improving the appearance quality of the handle holes. At the same time, the hot-pressing punching process is stable, the handle hole diameter is consistent, ensuring processing accuracy and improving product quality.
