The traditional way is manual placement. On the automatic production line, it is not suitable for automatic production operation to convey individual plug mould strips, so a carrier is needed to carry the plug mould strip, and the power plug is sent to different stations to complete the corresponding actions. Finally, the injection molding of the plug is completed at the injection molding station. The molded plugs are collected, and the carrier needs to return to the front end station of the production line for continuous use. The existing technology has a discontinuous cycle of plug mould strips, which has an interrupting link realized by manual handling. This way is low in production efficiency, high in labor intensity of workers, and wastes labor cost.

[0021] At this time, the carrier up-down moving mechanism at the end of the upper conveying line is located at the end of the upper conveying line, a carrier is pushed to the upper part thereof, the carrier up-down moving mechanism drives the carrier to move downward to the end of the lower conveying line, the left carrier pushing mechanism pushes the carrier to the lower conveying line, while the carriers on the lower conveying line move forward in sequence as a whole under the pushing of the left carrier pushing mechanism; then, the carrier up-down moving mechanism at the starting end moves downward to the end of the lower conveying line, so that the circulation conveying of the carrier is realized.

[0022] In summary, the carrier up-down moving mechanism at the starting end conveys the carrier from the lower part to the upper part, the carrier up-down moving mechanism at the end conveys the carrier from the upper part to the lower part, the carrier on the upper conveying line is pushed by the right carrier pushing mechanism, and the carrier on the lower conveying line is pushed by the left carrier pushing mechanism.

The carrier follow-up wheel mechanism is provided with support rollers and side sliding rollers of the carrier. The carrier limiting mechanism, the blocking mechanism, and the side sliding rollers position the carrier in front, back, left, and right directions, respectively.

[0027] The carrier on the conveying line moves to the carrier up-and-down moving mechanism through the rolling of the support rollers and the side sliding rollers. The carrier is positioned in front and back directions by the side sliding rollers, and in left and right directions by the carrier limiting mechanism and the blocking mechanism. In this way, the carrier is accurately positioned.

[0028] Further optimization scheme, the carrier limiting mechanism comprises a limiting block, a limiting guide rail block, and a limiting moving cylinder. The limiting block is provided with limiting moving rollers on both sides. The guide rail block is provided with a limiting guide rail groove with a height difference. The piston rod end of the limiting moving cylinder is movably connected to the limiting block. The limiting moving rollers move in the limiting guide rail groove.

[0029] The piston rod of the limiting moving cylinder is extended to drive the limiting block to move to a high position in the limiting guide rail groove and abut against the left inner wall of the plug carrier. The right blocking mechanism blocks the right inner wall of the plug carrier. The two mechanisms cooperate to position the plug carrier in left and right directions. The piston rod of the limiting moving cylinder is retracted to drive the limiting block to move to a low position in the limiting guide rail groove, releasing the plug carrier.

After moving inward simultaneously, they position and support the carrier from the inner and outer sides, respectively.

[0031] The outer side carrier pushing mechanism and the inner side carrier pushing mechanism move outward simultaneously to leave space for the upward movement of the carrier. Then, the carrier up-and-down moving mechanism moves the carrier upward to the end of the upper conveying line. The outer side carrier pushing mechanism and the inner side carrier pushing mechanism move inward simultaneously to hold the bottom of the carrier. In this way, the carrier up-and-down moving mechanism can move downward to continue conveying another carrier.

[0032] Further optimization scheme, the upper conveying line and the lower conveying line are respectively provided with a carrier positioning mechanism at the end of the conveying direction. The carrier positioning mechanism limits the carrier from moving forward and positions the carrier.

[0033] In a further optimized design, the right-push carrier mechanism includes a push rod assembly, a push guide rail assembly, and a push drive assembly. The push drive assembly connects to the push rod assembly and drives it to move back and forth on the push guide rail assembly. The end of the push rod assembly abuts against the middle of the carrier's push end. After pushing the carrier forward one carrier station on the upper conveyor line, it stops, returns to the starting position, and waits to push the next carrier.

[0034] In a further optimized design, the upper conveyor line's plug injection molding area is equipped with any of the aforementioned vehicle lifting mechanisms.

[0035] In a further optimized design, the left-pushing carrier mechanism includes a push rod assembly, a push guide rail assembly, and a push drive assembly. The push drive assembly is connected to the push rod assembly and drives it to move back and forth on the push guide rail assembly.

[0036] In a further optimized design, the push rod assembly includes a push rod seat, a second elastic element, and a push head. The end of the push rod seat is U-shaped with the opening facing downwards. One end of the upper part of the push head has a protrusion, which is movably hinged to the U-shaped opening of the push rod seat. The other end is provided with the second elastic element, which elastically presses against the U-shaped opening of the push rod seat. The protrusion on the push head abuts against the surface of the U-shaped opening of the push rod seat. The end of the push head opposite the push end has an end face that is inclined towards the push end.

[0037] The push head of the push rod assembly pushes the carrier in the conveying direction against the side of the carrier. After being pushed into place, the push rod assembly resets. At the end of the lower conveyor line in the conveying direction, the push head of the reset push rod assembly needs to cross one end of the carrier and abut against the inner side of that end. The carrier abuts against the inclined end face of the push head at that end and pushes it upward. This action crosses that end of the carrier. After the push rod assembly resets, the push head moves down under the action of the second elastic element and abuts against the inner side of that end to push the carrier.

[0038] A plug injection molding line includes a carrier circulation mechanism for any of the above-described automatic plug injection molding lines.

[0039] This utility model has the following technical advantages compared with the prior art:

[0040] The plug mold strip carrier, carrier lifting mechanism, plug injection molding line carrier circulation mechanism, and plug injection molding line all use a carrier to carry the plug mold strip. An automated carrier conveyor line is formed by an upper conveyor line, a lower conveyor line, a carrier up-and-down moving mechanism, a right-push carrier mechanism, and a left-push carrier mechanism. The automated conveyor line connects the carrier end to end without interruption, eliminating the need for manual handling and achieving automatic cyclical transport of the carrier.
