The invention discloses a cast anchor cup, a cable and a process for manufacturing the same, and relates to a cast anchor cup, a hot-cast anchor cable and a process for manufacturing the same. The cast anchor cup comprises an anchor cup body, a lengthening sleeve and a constraint positioning ring. An end of the lengthening sleeve extends into the anchor cup body and is connected with the anchor cup body in a threaded manner, and the constraint positioning ring is arranged in the lengthening sleeve and is positioned at the lower end of the lengthening sleeve. The cable comprises a cable body, the cast anchor cup and cast anchors. The cast anchor cup and the cast anchors are fixedly connected with two ends of the cable body. The process for manufacturing the cable includes casting the lengthening sleeve and the anchor cup body with each other. The cast anchor cup, the cable and the process have the advantages that the structure of the cast anchor cup is improved, the lengthening sleeve and the constraint positioning ring are designed, accordingly, the cast anchor cup and the cable body can be accurately positioned relative to each other, casting tools do not need to be designed, manufactured and mounted, and the cable manufacturing efficiency can be improved; the lengthening sleeve and the anchor cup body are cast with each other, the steel wire anchorage lengths can be prolonged, steel wires can be prevented from being broken away, and accordingly the quality of the cable can be improved.
