[0029] The working principle of the above embodiment is:

[0030] When demolding the rubber boot mold with the top-middle-frame structure, the front and rear cylinders are started to lift the upper cover plate 44 and the upper inner core 47, so that the upper inner core 47 is separated from the middle frame 43, and then the left and right cylinders are started to lift the middle frame 43 and the lower inner core 46, so that the ejector rod 3 passes through the lower inner core 46 and pushes the rubber boot out, thereby completing the demolding operation. In addition, when replacing the mold 4, the electric push rods in the two feeding components 54 are started, and the electric push rods are contracted and driven to move the positioning frames 53, and the two positioning frames 53 are controlled to move to opposite sides, thereby releasing the fixation of the mounting plate in the mold 4, until the connecting bracket 52 squeezes the pressure sensor and triggers the shutdown of the electric push rod, so as to facilitate the staff to quickly disassemble and replace the mold 4.
