In the state of fig. 6, the output end of the blocking cylinder 194 is retracted, and the blocking wheel 193 is higher than the height of the two timing belt rails, so that the mold device 20 placed on the timing belt rails can be blocked. When the output end of the blocking cylinder 194 extends, the blocking member 192 is pushed to rotate, and the blocking wheel 193 at one end is driven to rotate to a height lower than the upper surface of the timing belt rail, so that the loaded mold device 20 can be released.

Based on the structure, the situation of assembly product switching can be dealt with. When the automobile door plates of the same type are continuously assembled, the mold receiving unit 61 of the fifth station descends under the control of the industrial personal computer, and the vacant mold device 20 is directly conveyed back to the first station through the backflow conveying device 71 to be reused. When the assembled product is switched, the used mold device 20 at the fifth station is stored in the temporary mold storage device 100, and then an assembling worker can put another mold device 20 of a corresponding type into the first station, or the assembling worker is controlled by an industrial personal computer to take out the mold device 20 of the corresponding type stored in the temporary mold storage device 100 and put the mold device into the lower layer of the fourth station, and then the mold device is conveyed to the first station for use through the backflow conveying device 71.
