Wrapped type pipe manufacturing mold core assembly

Abstract

The invention relates to a wrapped type pipe manufacturing mold core assembly. The wrapped type pipe manufacturing mold core assembly comprises two end molds, two or more upright rods, one or more telescopic mechanisms and a wrapping layer, wherein the two end molds are coaxially arranged in a spaced mode; the upright rods are inserted on the inner sides of the two end molds and parallel to the center axes of the end molds; the telescopic mechanisms are used for unfolding the upright rods with the center axes of the end molds being centers towards the outer sides; and the wrapping layer is wrapped on the part, between the two end molds, of the peripheries of the upright rods and forms a continuous pipe-shaped structure. The provided wrapped type pipe manufacturing mold core assembly is convenient to demold and reusable. The wrapped type pipe manufacturing mold core assembly has the advantages that materials are sprayed on the vertical surfaces of a pipe-shaped mold plate formed by the wrapping layer through the spraying assembly, forming of a pipe body can be completed rapidly, and the forming quality is high; moreover, after the pipe body is solidified, the mold core assembly can be taken out by being contracted, and repeated utilization is achieved; and in addition, the wrapping layer can be made of disposable materials and do not need to be recycled, and time and effort are saved.

Description

technical field [0001] The invention relates to a pipe manufacturing equipment, in particular to a packaged pipe-making mold core assembly. Background technique [0002] At present, pipes (flue pipes or exhaust pipes) are usually made of manual pouring filling, which has low production efficiency and difficult to unify quality standards. Contents of the invention [0003] The object of the present invention is to provide a reusable wrapped pipe-making core assembly which is easy to demould. [0004] The purpose of the present invention is achieved through the following technical solutions: a wrap-type pipe-making mold core assembly, which includes two coaxial end dies arranged at intervals, two or more end dies inserted inside the end dies and connected to the central axis of the end dies. Parallel vertical rods, more than one telescopic mechanism for expanding each vertical rod to the outside with the central axis of the end mold as the center, and a wrapping layer wrapp...
