Embodiment Construction

[0023] The present invention will be further explained below in conjunction with the accompanying drawings. The accompanying drawings are for illustrative purposes only, and cannot be construed as limiting the present invention; in order to better illustrate this embodiment, some parts in the accompanying drawings will be omitted, enlarged or reduced; for those skilled in the art, certain parts in the accompanying drawings It is understandable that some well-known structures and descriptions thereof may be omitted.

[0024] like figure 1 As shown, a PP-R pipe mold includes a mold connecting part, a mold plasticizing part and a mold forming part, and the mold connecting part, the mold plasticizing part and the mold forming part are sequentially connected. The plasticizing part of the mold includes a mold base 1, an outer mold body 3 and a spiral body 2 arranged on the mold base 1, a splitter plate 4 arranged on the outer mold body 3 and the spiral body 2, and the outer mold bo...

Abstract

The invention relates to a PP-R pipe mould which comprises a mould connecting part, a mould plastifying part and a mould forming part; the mould connecting part, the mould plastifying part and the mould forming part are sequentially connected. The mould connecting part, the mould plastifying part and the mould forming part are formed into an integer, plastic melt enters the mould from the mould connecting part and spirally moves in an axial direction in the mould plastifying part, so that plastic melt plastifying effect is strengthened, and finally formed pipe blank leaves the mould from the mould forming part. The PP-R pipe mould is compact in structure, is simple in production operation, effectively improves the problem that a PP-R pipe easily generates confluence lines, air pores and crystal points, can be suitable for production use of PP-R pipe products of the same type, is extremely high in production stability, effectively improves product quality and reduces a production rejection rate.

Description

technical field [0001] The invention relates to the technical field of plastic pipe production, more specifically to a PP-R pipe mold. Background technique [0002] At present, the production mold of PP-R pipes generally adopts a spiral mold or a blue mold. When the plastic melt is formed and plasticized in the mold, because the flow direction of the plastic melt always makes a single movement, the flow of the plastic melt in the mold Plasticization is often insufficient, which causes pipe products to easily have crystal points or merge lines that cannot be eliminated, especially for some added color masterbatches, which cannot achieve a better dispersion effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a PP-R pipe mold in which the plastic melt spirals in the axial direction and solves the problem of insufficient plasticization of the plastic melt in the mold...
