The inner core mold is sleeved inside the rubber pipe, and it is not easy to remove the inner core mold. In addition, the temperature of the mold itself is still very high after vulcanization, making the demolding operation more difficult. The rubber pipe is often damaged during the demolding process. The damaged pipe is cut into small sections by a cutting machine and reheated and edge-sealed for secondary use.
[0003] The existing heating edge sealing is done by placing the heating cover on the surface of the heating roller and pressing it tightly, which can easily cause burns to the operator, and wrinkles will appear at the joints when the interface is pressed and sealed manually, affecting the later use of the heated pipe. To this end, we provide a pipe mold heating edge sealing equipment to solve the above problems. Utility Model Content

After the heating is completed, the mold body 8 after heating and pressing can be taken out through the gap in the middle by disassembling the fixing component 5, which is more convenient for personnel to operate and can avoid burns to a certain extent. A rotating motor 3 is fixedly arranged on the fixing frame 2. The output shaft of the rotating motor 3 is fixedly connected to the heating cover 6 on the surface of the heating roller 13 through the fixing rod 4. The heating cover 6 can be rotated and opened by the rotating motor 3 in cooperation with the fixing rod 4, avoiding manual opening by personnel and reducing burns. Compared with traditional manual pressing, the pressing force of the heating cover 6 on the mold body 8 can be effectively improved to avoid falling off during edge sealing, and it is also convenient for later heating edge sealing.
[0025] Specifically, Figure 1-3 and Figure 5As shown, a groove 12 is provided in the base 1, and a tensioning mechanism 11 is provided inside the groove 12. The tensioning mechanism 11 also includes a tensioning motor 111 provided in the groove 12. Threaded rods 112 with opposite threads are fixed at both ends of the tensioning motor 111.
