The application belongs to the technical field of medical dilatation tube manufacturing, and discloses a full-automatic medical dilatation tube hot melting forming device, which comprises a hot melting box and a screw extruder, the hot melting box is connected with the screw extruder through a
discharge pipe, a controller is arranged on the hot melting box, an inclined angle
machine head is connected to the
discharge end of the screw extruder, a forming die sleeve is threadedly connected to the end of the inclined angle
machine head, a die core is arranged in the forming die sleeve, a cooling box is arranged on one side of the hot melting box, through holes are formed in the two sides of the cooling box, the forming die sleeve extends into the cooling box through the through holes, and a cold gas spraying
assembly is arranged in the cooling box and is on the same straight line as the center of the forming die sleeve. According to the scheme, the cold gas output mechanisms are arranged on the inner wall and the outer wall of the forming dilatation tube extruded from the forming die sleeve and the die core to perform cooling, on the one hand, the
cooling efficiency can be further improved, and on the other hand, the
processing technology of the dilatation tube is simplified, and subsequent
drying treatment is not needed, so that the
cooling time is saved.
