This utility model discloses an electric telescopic tool for hot water bag production. It relates to the field of hot water bags and aims to solve the problem that when the mold core is removed from the bag opening, the lack of air or even negative pressure inside the hot water bag leads to high friction between the mold core and the bag opening, making removal very difficult. The key technical point is that it includes a positioning cylinder and a telescopic cylinder. The telescopic cylinder is slidably positioned at one end of the positioning cylinder. A first fork is vertically arranged at the end of the positioning cylinder away from the telescopic cylinder, and a bent second fork is fixedly arranged at the end of the telescopic cylinder away from the positioning cylinder. The second fork is parallel to the first fork and fits against it. During the separation of the hot water bag, the tool achieves easy and effortless separation of the hot water bag and the mold core by disrupting the internal negative pressure environment and assisting in opening the bag opening.
