[0036] Next, the telescopic end of the first stroke cylinder 85 in the first inner molding component 8 is driven to extend outward so as to drive the inner cone head 83 to move toward the upper end opening of the curved tube-shaped chamber with the help of the extension rod 86, so that each first positioning strip 831 is embedded in a corresponding first positioning groove 8212, and at the same time, each second positioning strip 8222 is embedded in a corresponding second positioning groove 832, so that the inner cone head 83 and the outer cone sleeve 82 are mutually fitted, so as to drive the first slider 81 to move synchronously with the help of the outer cone sleeve 82 until the first molding head 84 extends into the upper end of the curved tube-shaped chamber; at the same time, the telescopic end of the second stroke cylinder 93 in the second inner molding component 9 is driven to extend outward so as to drive the second molding head 92 to move toward the lower end opening of the curved tube-shaped chamber with the help of the second slider 91 until the second molding head 92 extends into the lower end of the curved tube-shaped chamber, and finally the limiting protrusion 842 on the first molding head 84 is embedded in the limiting concave cavity 943 on the second molding head 92.

[0037] Afterwards, the molten material enters the movable module 2 through the gate provided in the feed plate 1, and then enters between the first molding cavity 31 on the movable mold core 3 and the second molding cavity 51 on the fixed mold core 5 through the runner provided in the movable module 2, and wraps the first arc-shaped turning portion 841, the straight cylinder portion 921 and the second arc-shaped turning portion 921, and forms a quick-plug connector 11 after cooling; then, the feed plate 1 is driven to move forward by means of the action mechanism, thereby driving the movable module 2 away from the fixed module 4, so that the first molding cavity 31 is separated from the second molding cavity 51, and then the molded quick-plug connector 11 is ejected forward by means of the ejection mechanism 7 (prior art); in the process of moving forward, the movable module 2 will force the third slider 101 to move in the opposite direction to reset by means of the driving rod 102 in the same way; each molding notch 1012 will form each arc-shaped buckle strip 111 on the outer wall of the quick-plug connector 11 with a corresponding first arc-shaped molding groove 33 or second arc-shaped molding groove 53.

[0038] The utility model divides the originally integral inner core into two to form a first molding head 84 and a second molding head 92, and provides a first inner molding component 8 and a second inner molding component 9 which can independently drive the first molding head 84 and the second molding head 92 to move. Since the lengths of the first molding head 84 and the second molding head 92 almost evenly divide the length of the originally integral inner core, the first molding head 84 and the second molding head 92 can easily avoid collision with the inner wall of the curved tube-shaped chamber, thereby dividing the originally integral inner core moving stroke into two, and there is no need to adjust the moving direction, thereby reducing the demolding difficulty and greatly shortening the time required for mold positioning and demolding, while simplifying the structure to simplify the manufacturing process.
