Abstract
The rectangular rib cladding die of the utility model is formed by sequentially sleeving a die core, a die sleeve, a transition sleeve A, a transition sleeve B, a forming inner sleeve, a forming outer sleeve and a pressing sleeve, and all the components are concentrically matched; the outer circles and the inner sides of the forming inner sleeve and the forming outer sleeve are square; the die sleeve is provided with a hole. The inner square size of the forming inner sleeve and the forming outer sleeve of the utility model is designed according to the size of the square ribbed tube with clearance. The utility model coats the rectangular PP corrugated pipe with the melted HDPE material flow to form a rectangular reinforcing rib belt; the rectangular reinforcing rib belt and the molten HDPE flat belt are hot-melted together on a heated steel roller die to form the HDPE high-rib winding reinforcing pipe which has high rigidity, no cracking and peeling, large current-carrying capacity, environmental protection and no pollution.
Description
Technical Field
The utility model relates to a rectangle rib cladding mould.
Background
The existing PP double-high-rib reinforced polyethylene winding pipe is continuously produced by cold winding, reinforcing ribs of the existing PP double-high-rib reinforced polyethylene winding pipe are arc-shaped, two PP pipes are coated by polyethylene and are bonded by a chemical adhesive, and thus the produced winding pipe is easy to delaminate and peel off and has leakage hidden trouble.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a rectangle rib cladding mould, it lets rectangle PP bellows flow the cladding through fused HDPE, forms rectangle reinforcing rib area. The rectangular reinforcing rib belt and the molten HDPE flat belt are hot-melted together on a heated steel roller die to form the HDPE high-rib winding reinforcing pipe which has high rigidity, no cracking and peeling, large current-carrying capacity, environmental protection and no pollution.
The utility model is realized in such a way that the rectangular rib cladding mould is formed by sequentially sleeving a mould core, a mould sleeve, a transition sleeve A, a transition sleeve B, a forming inner sleeve, a forming outer sleeve and a pressing sleeve, and all the components are concentrically matched; the outer circles and the inner sides of the forming inner sleeve and the forming outer sleeve are square; the die sleeve is provided with a hole.
The inner square size of the forming inner sleeve and the forming outer sleeve of the utility model is designed according to the size of the square ribbed tube with clearance.
The beneficial effects of the utility model are that the HDPE rectangular ribbed pipe produced by the utility model is driven by the rectangular PP corrugated pipe, and is conveyed to the heated steel roller mould to be hot-melted with the hot melting flat belt to form a rectangular reinforcing rib winding pipe; the method is particularly suitable for manufacturing large-caliber high-ring stiffness pipes, and the ribbed pipes with the height of more than 65mm must be adopted when the pipe diameter exceeds 1.2 m.

In the figure: 1. the high-strength HDPE corrugated pipe comprises a mold core, 2 parts of a mold sleeve, 3 parts of a transition sleeve A, 4 parts of a transition sleeve B, 5 parts of a forming inner sleeve, 6 parts of a forming outer sleeve, 7 parts of a pressing sleeve, 8 parts of holes, 9 parts of an HDPE high-rib winding reinforcing pipe, 10 parts of a bell mouth, 11 parts of a rectangular reinforcing ribbed pipe, 12 parts of a socket, 13 parts of a rectangular PP corrugated pipe and 14 parts of an HDPE coating layer.
Detailed Description
The rectangular rib cladding die of the utility model is formed by sequentially sleeving a die core 1, a die sleeve 2, a transition sleeve A3, a transition sleeve B4, a forming inner sleeve 5, a forming outer sleeve 6 and a pressing sleeve 7 as shown in figures 1-6, and all the components are concentrically matched; the outer circles of the forming inner sleeve 5 and the forming outer sleeve 6 are inward; the die sleeve is provided with a melt inlet hole 8.
The inner square size of the forming inner sleeve 5 and the forming outer sleeve 6 is designed to be clearance according to the size of the square ribbed tube. In FIG. 5, HDPE high-rib winding reinforced pipe 9, bell mouth 10, rectangular reinforced ribbed pipe 11 and spigot 12 are marked. The cross-section of figure 6 is indicated by rectangular PP corrugated pipe 13, HDPE cladding 14.
Use the utility model discloses the process of production HDPE rectangle reinforcing rib pipe 11 is, and hot melting HDPE material is extruded to the extruder, and in the melt got into rectangle rib cladding die cavity, along the diffluent diffusion of die cavity gap, extrude in the rectangle gap between shaping endotheca and the shaping overcoat at last, and at the uniform velocity is worn out in the hole of rectangle PP bellows follow shaping endotheca, and the HDPE melt cladding forms certain thickness HDPE rectangle reinforcing rib pipe on rectangle PP bellows 13. The HDPE rectangular reinforcing ribbed pipe is driven by the rectangular PP corrugated pipe to be conveyed to a heated steel roller die to be hot-melted with the hot melting flat belt, and an HDPE high-rib winding reinforcing pipe 9 with a smooth inner surface, a spiral outer wall and an integrally formed spigot-and-socket joint is formed.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
