Abstract
The utility model relates to a mould core used for manufacturing a composite material pipe, which solves the problem of demoulding. The mould core for manufacturing a composite material pipe comprises a core rod and a brush object. The mould core is characterized in that the outer part of the core rod is provided with the brush object, and the brush object is a transportable material. The mould core is used for manufacturing thin pipe products with various shapes.
Description
The utility model relates to the tubulation core rod, refers to a kind of making composite material tube especially, comprises the minimum tubule of ips, special pipe etc., has solved the core rod that a demoulding difficult problem is used by this.
In the existing composite material tube manufacture craft, generally adopt the metal core rod, its method is earlier by tubing products internal diameter requirement processing metal core rod, makes tubing products with it again, after completing, adopts mechanical means that core rod is extracted from type tubing products.Use this process, comprise with this metal core rod and make tubing products, if ips small-sized (as several millimeters), even if pipe is the band tapering, and length is little, and it also is very difficult making the metal core rod, and the cost height, quality is difficult to guarantee, even if like this, the demoulding is also very difficult, as if making not with the tapering straight tube in this way or having crooked special pipe, even the tubing products internal diameter is big, also can't realize.For example: making internal diameter 4mm, a length is the tubule of the zero draft of 1.5mm, adopts metal bar through the external diameter 4mm of strict alignment as core rod, after completing, can't the demoulding obtain tubing products.Using which type of core rod in the technology, is a key technical problem.
The purpose of this utility model is exactly to disclose a kind of new effective core rod of process making composite that is used to adopt.
The purpose of this utility model is achieved in that composite material tube manufacture craft core rod, comprises plug, brushing thing, it is characterized in that being provided with the brushing thing in this plug outside, and this brushing thing is transportable material.
The external diameter that adopts above-mentioned core rod utilizes the transportable characteristic of plug outside coating thing less than the plug of the tubing products internal diameter liner portion as the tubing products core rod, just can produce the tubing products of various requirement easily.
The utility model is described in further detail below by embodiment and accompanying drawing.
Fig. 1, be one of the utility model embodiment schematic diagram; Fig. 2, be two schematic diagrames of the utility model embodiment; Fig. 3, be three schematic diagrames of the utility model embodiment; Fig. 4, be four schematic diagrames of the utility model embodiment; Fig. 5, be five schematic diagrames of the utility model embodiment;
As shown in the figure, plug can be straight-bar shape 1 or taper 2 or arc 3 or abnormity 4 or variable cross-section shape 5, and is provided with brushing thing 6 respectively in the outside of these plugs.It is worthy of note that thereby plug can be made by flexible material and have proper flexibility.The meaning of this patent just is to have solved the demoulding difficult problem of straight tube and special pipe like this, and especially when the internal diameter of tubing products was very little, this method just more demonstrated its advantage.It is the requisite critical product that a kind of easy, practical demoulding new technology is used.
