Abstract
The invention provides a die sleeve. A die is located in a cavity formed by the die sleeve. The die sleeve protrudes out of an extruder head so that the die can get away from the extruder head conveniently for quick replacement, and safety of the die is ensured. The die sleeve comprises a secondary die sleeve. An inner cavity of the secondary die sleeve is used for containing the die. The secondary die sleeve is mounted in a die mounting cavity of the extruder head in a stuffed mode. The outer ring surface of the secondary die sleeve is attached to the inner wall of the extruder head. The inner ring surface of the front end of the secondary die sleeve is provided with an internal thread. A die sleeve fixing flange sleeve is mounted on a locating outer ring surface of the secondary die sleeve. An external thread of the locating end of the die sleeve fixing flange sleeve is used for fastening the locating end of the thread of the inner ring surface of the extruder head. An external thread of the rear end of a pull sleeve of the secondary die sleeve is connected with the internal thread of the inner ring surface of the front end of the secondary die sleeve. A locating sleeve structure is mounted in a space between the outer ring surface of the front end of the secondary die sleeve and the inner ring surface of a die sleeve fixing flange.
