[0007] A mandrel is inserted into the gap at the end of the molding die cylinder away from the fixing seat, and a sealing cover is fixed to the mandrel;

[0008] The sealing cover is connected with a driving mechanism, which is installed on a molding workbench. The driving mechanism drives the sealing cover to move horizontally, so that the sealing cover is automatically drawn out of or pushed into the mold shell with the mandrel.

[0009] A cooling mechanism for cooling is installed outside the molding die cylinder.

[0010] The cooling mechanism comprises a water pipe attached to the outside of the forming mold cylinder, the water pipe is connected to a water tank through a water pump, and the water tank is supported and embedded in the inner surface of the bottom of the forming workbench through a fixed plate.

[0011] The forming mold barrel is provided with a hopper; the water tank far from the hopper is connected with the end of the water pipe through a return pipe, and the water tank close to the hopper is connected with the end of the water pipe through a water pump.

[0012] The water pipe is in a fishbone shape and is evenly attached to and wrapped around the outside of the forming mold cylinder.

[0013] The driving mechanism comprises a moving plate fixed to the sealing cover, a sliding plate fixed to the lower part of the moving plate, a limiting plate with a T-shaped cross section fixed to the top surface of the sliding plate, and the limiting plate and the bottom surface of the fixed plate can only be slidably matched;

[0014] It also includes a threaded rod, the sliding plate and the threaded rod are screwed together through a thread pair, and the threaded rod is located below the fixed plate;

[0015] The drive motor is also included, which is fixed to the shell and the forming workbench. One end of the threaded rod is connected to the drive motor. The drive motor rotates the output shaft to drive the threaded rod to rotate. The other end of the threaded rod is rotatably mounted with a fixed frame through a bearing. The fixed frame is fixed on the forming workbench. The drive motor drives the threaded rod to rotate. When the threaded rod rotates, the sliding plate drives the sealing cover to perform horizontal displacement through the moving plate under the action of the sliding cooperation between the limit plate and the bottom surface of the fixed plate, so that the sealing cover can be automatically pulled out or pushed in from the mold shell with the core shaft.

[0016] The beneficial effect of the present invention is that the sealing cover can be horizontally displaced by the driving mechanism on the forming workbench, so that the sealing cover can be automatically pulled out of or pushed into the mold shell with the mandrel, thus solving the problem of high labor intensity and low efficiency in the prior art in which personnel twist the sealing cover to pull out the mandrel.
