Hot plate welding die

The hot plate welding die comprises a machine body, the upper portion and the lower portion of the interior of the machine body are each provided with a base, a lower die is fixedly installed on the upper portion of the lower base, and an upper die is fixedly installed on the lower portion of the upper base. Through the arrangement of the cleaning mechanisms, after the upper and lower heating plates heat and melt the upper and lower plastic products, the upper and lower heating plates retreat from the space between the upper and lower molds, and then in the process that the two heating plates move towards the back of the machine body, the two heating plates are scraped by upper and lower scrapers of the two cleaning mechanisms; the problem that plastic attached to the heating plates is removed is solved, the heating plates are continuously heated for a long time, therefore, the attached plastic cannot be severely bonded with the heating plates, the two scrapers can conveniently scrape the two heating plates,
