Double-wall pipe mold inner wall die transition sleeve and its disassembly tool

Abstract

The invention discloses a transition sleeve for an inner wall die of a double-wall pipe mold and a disassembly tool thereof. The double-wall pipe mold includes an inner wall die and an outer wall die, and the inner wall die includes an inner wall die connecting sleeve and an inner wall die transition sleeve arranged in sequence in the axial direction. And the inner wall die, the inner wall die transition sleeve is installed on the inner wall die connection sleeve, the inner wall die is installed on the inner wall die transition sleeve, and the outer peripheral wall of the inner wall die transition sleeve is provided with a plurality of axially extending card slots , one end of the inner wall die transition sleeve has a transition surface capable of smoothly transitioning to the inner wall surface of the inner wall die. The assembly and disassembly tool is in the shape of a cylinder, one end of which is axially extended and provided with an extension part matching the slot on the transition sleeve of the inner wall die, and the other end has an operating part. When adjusting the thickness of the inner wall, the mold only needs to rotate the inner wall die to enter and exit, but the transition surface can still smoothly transition to the inner wall surface of the inner wall die, avoiding gaps and material leakage in the traditional technology, thereby avoiding downtime for repairs. Effectively guarantee the production efficiency.

Description

technical field [0001] The invention relates to a transition sleeve for an inner wall die of a double-wall pipe die and a disassembly tool thereof. Background technique [0002] The double-wall pipe mold includes an inner wall mold for forming the inner wall and an outer wall mold for forming the outer wall. The inner wall mold in the traditional technology includes an inner wall die connecting sleeve and an inner wall die connected axially. The inner wall die passes through The internal thread is screwed tightly on the outer wall at the end of the connecting sleeve of the inner wall die, and the two are assembled through the concave platform and the convex platform. When adjusting the thickness of the inner wall, it is necessary to rotate the inner wall die so that the inner wall die is relative to the inner wall. The die connecting sleeve moves axially, so that there is a gap between the concave platform and the convex platform, and the inner wall material will leak from t...

When adjusting the thickness of the inner wall, it is necessary to rotate the inner wall die so that the inner wall die is relative to the inner wall. The die connecting sleeve moves axially, so that there is a gap between the concave platform and the convex platform, and the inner wall material will leak from this gap, which will affect the normal production
