The device is placed stably through the two support mechanisms. Step 2: Pull the lever (36) to disengage the locking block (37) from the corresponding slot, and push the mounting plate (8) to rotate the sleeve (7) half a turn on the second column (4). Under the elastic force of the spring (35), the locking block (37) extends into the slot directly below, thereby fixing the position of the mounting plate (8) and the spraying mechanism.

The release agent is sprayed down to the left edge of the mold cavity through multiple first nozzles (19) on the first mounting tube (17) and up to the left edge of the mold cavity through multiple second nozzles (20) on the second mounting tube (18). Then, the stepper motor (23) is automatically started to drive the first mounting tube (17) and the second mounting tube (18). Rotate a certain angle so that the first nozzle (19) and the second nozzle (20) face the upper mold and the lower mold, and continue to spray the release agent on them. After a certain period of time, the stepper motor (23) is automatically started to reverse, which drives the first mounting tube (17) and the second mounting tube (18) to rotate in the opposite direction by a certain angle, so that the first nozzle (19) sprays the release agent on the right edge of the lower mold cavity, and the second nozzle (20) sprays the release agent on the right edge of the upper mold. Then turn off the infusion pump (9) so that the release agent is fully sprayed on the edge of the upper mold and the edge of the lower mold cavity, so that the workers can easily remove the molded car foam seat. Step 4: The stepper motor (23) is automatically controlled by the controller (46) to restore the first nozzle (19) and the second nozzle (20) to their initial angles, in preparation for spraying the release agent onto the next mold.
