[0040] When this solution works, it includes the following steps:

[0041] S1. After the male and female parts of the injection molded parts are buckled together, they are placed on the feeding conveyor line 2. When the injection molded parts move to the end of the feeding conveyor line 2, the injection molded parts encounter the two-way cylinder 507, the two-way cylinder 507 contracts, and the two clamping blocks 508 approach each other to clamp the injection molded parts; then the feeding slide cylinder 504 is actuated, and the injection molded parts move upward; the slider of the first rodless cylinder 501 moves backward, and the feeding slide cylinder 504 and the injection molded parts are moved to the lower pressure platform 421, and then the clamping blocks 508 are released to place the injection molded parts on the lower pressure platform 421;

[0043] S3, the pressure mechanism 410 is actuated to drive the pressing table 414 downward to press the male part and the female part together, and then the second linear cylinder 415 is actuated to press the stripping frame 418 onto the pressed injection molded part, and the pressure mechanism 410 is actuated to drive the pressing table 414 upward to separate the pressing table 414 from the surface of the injection molded part, and then the stripping frame 418 is upward; the purpose of the stripping frame 418 is mainly to prevent the pressing table 414 from lifting the injection molded part after the bottom of the pressing table 414 is adhered to the surface of the injection molded part;

[0044] S4, the lifting frame 422 moves upward until it is flush with the surface of the conveyor belt of the unloading conveyor line 3. The functions of the lifting frame 422 are to lift the injection molding platform to be flush with the surface of the conveyor belt of the unloading conveyor line 3 and to separate the injection molding from the lower pressure platform 421;

[0045] S5, repeat step S1, but before the slider of the first rodless cylinder 501 moves backward, the slider of the unloading slide cylinder 505 moves downward so that the unloading fork 509 is aligned with the front side of the injection molded part. As the slider of the first rodless cylinder 501 moves backward, the unloading fork 509 moves the injection molded part on the lifting frame 422 to the unloading conveyor line;

[0046] Repeat the above steps.
