The utility model discloses a multifunctional portable hot-runner spring heating device, comprising a power connector, a wire, an adapter and an electric heating tube. The power connector is connected to the wire, and the wire is connected to an electric heating wire inside the electric heating tube through the adapter. The electric heating tube is a helical spring type, and the structure of the electric heating wire inside is as follows: the same electric heating wire is folded in half and runs through the electric heating tube, with the folding point located inside the end of the electric heating tube away from the adapter. The utility model adopts a helical spring electric heating tube as the heating body, making it elastic and applicable to environments where fixed-shape heating bodies cannot achieve heating, such as hot-runner plastic molds, nozzles and edge sleeves of blow molding machines and extruders, filling the gap in local heating in the existing electric heating field.
