The body 1 is equipped with an infeed mechanism 2, a fixture mechanism 3, a loading mechanism 4, a feeding mechanism 5, a drain mechanism 6, a discharge mechanism 7, and a finished product collection mechanism 8. The loading mechanism 4, feeding mechanism 5, discharge mechanism 7, and fixture mechanism 3 form a transmission loop for transmitting a fixture 9. The infeed mechanism 2 is used to load wires into the unloaded fixture 9. The loading mechanism 4 is used to transfer the fixture 9 loaded with wires to the discharge mechanism 8. The feeding mechanism 5 is used to transfer the jig 9 loaded with wire to an external injection molding machine for injection molding; the sprue removal mechanism 6 is used to remove the sprues on the injected wire; the unloading mechanism 7 is used to transfer the jig 9 loaded with finished wire to the finished product collection mechanism 8; the finished product collection mechanism 8 is used to remove the finished wire from the jig 9; the jig mechanism 3 is used to transfer the jig 9 after removing the wire to the loading mechanism 4, and the wire is loaded by the feeding mechanism 2 during the transfer process.
[0039] During operation, the feeding mechanism 2 first transfers the external wire to the empty fixture 9 until the fixture 9 is completely filled with wire. Then, the loading mechanism 4 moves the fixture 9 containing the wire laterally to the feeding mechanism 5. The feeding mechanism 5 then moves the fixture 9 longitudinally to the external injection molding machine, where the wire loaded in the fixture 9 is injection molded. Next, the sprue removal mechanism 6 removes the sprues from the molded wire, forming a finished wire. Finally, the unloading mechanism 7 transfers the fixture 9 containing the finished wire to the finished product collection mechanism 8. The finished product collection mechanism 8 removes the finished wire from the fixture 9 and transfers it to an external working mechanism for further processing. The fixture mechanism 3 is located between the loading mechanism 4 and the unloading mechanism 7. The fixture mechanism 3 can transfer the empty fixture 9 after removing the wire back to the loading mechanism 4, so that the loading mechanism 4 can start a new round of injection molding production, thereby realizing uninterrupted injection molding production. Since each mechanism is electrically connected to the PLC control system, the operation is efficient and easy to manage.
