Abstract
The present invention relates to a manufacture process for a novel silicon rubber pipe and a special mold core thereof. The manufacture process is characterized in that the manufacture process includes the following steps: a, a rubber pipe stock is directly formed on the surface of a rubber bag of which the inner diameter corresponds to that of the rubber pipe; b, the shaped rubber pipe stock and the rubber bag are together placed in a mold cavity of a mold; c. the mold is closed, and internal pressure is filled in the rubber bag to carry out vulcanization; d, the vulcanization is completed, pressure is relieved, the rubber bagis drawn out, and the rubber pipe is obtained. In addition, the special mold core of the manufacture process for a novel silicon rubber pipe of the present invention is characterized in that the mold core is the rubber bag. The manufacture process for a novel silicon rubber pipe not only solves the problems that a reinforced layer is easy to press to break in the production of silicon rubber pipes and demoulding is difficult existing in the prior art, but also produces products with good quality and without burrs and deckle edges.
Description
Technical field
The present invention relates to a kind of New Type Silicone Rubber Hose Production Process.
Background technology
Existing silicon rubber sebific duct production technology mainly adopts (as iron core, aluminium core etc.) preformed of hard core or direct blowing (silicon rubber) in mould cavity, pressurizes on mould then, makes silicon rubber be full of die cavity by external pressure and vulcanizes.There is following critical defect in this production technology when producing sebific duct: the one, when making the bellows sebific duct, the ripple projection consistent with die cavity must be arranged on the core rod, therefore producing the later stage exists the problem of demoulding difficulty, the demoulding for convenience during production, core rod is linked together (as shown in Figure 1) by several sections core rod sections, but because there is seam in core rod section junction, cause on the product inwall of producing and leave burr, burr (as shown in Figure 3), if will have burr, the sebific duct of burr is brought in the diesel engine supporting with it and is used, will cause diesel engine piston to damage in early days, have a strong impact on the service life of diesel engine; The 2nd, the sebific duct enhancement layer when the matched moulds pressurized (as shown in Figure 2, arrow is a direction of exerting pressure) easily by the mould extrusion fracture, the product section of production is inhomogeneous, fold often occurs, has had a strong impact on the quality of product.Therefore, utilize existing manufacturing technique to produce the silicon rubber sebific duct of silicon rubber sebific duct, particularly many ripples, not only comparatively difficult, and also the product quality of producing can not be guaranteed.
Summary of the invention
The invention provides a kind of New Type Silicone Rubber Hose Production Process, the problem that it has not only solved the easy extrusion fracture of enhancement layer in the production of existing in prior technology silicon rubber sebific duct and has been difficult to the demoulding, and the good product quality of producing, no burr, burr.
One of technical scheme of the present invention provides a kind of New Type Silicone Rubber Hose Production Process, it is characterized in that, its processing step is as follows:
A. coat interleaving agent on the surface of the capsule that adapts with the sebific duct internal diameter, with the surface of sizing material attached to the capsule that has interleaving agent on, be wrapped with water cloth after the moulding again, thereby straight forming sebific duct blank;
B. the sebific duct blank of forming is put into mould cavity together with capsule;
C. matched moulds is squeezed into interior pressure to capsule, vulcanizes;
D. sulfuration is finished, and capsule is extracted in release, obtains sebific duct.
Two of technical scheme of the present invention provides a kind of special-purpose core rod of New Type Silicone Rubber Hose Production Process, it is characterized in that, described core rod is a capsule.
Compared to prior art, press to vulcanize in the present invention applies preformed sebific duct blank by capsule and produce the silicon rubber sebific duct, because the capsule material is soft, neither can be expressed to the enhancement layer of product during matched moulds, can make pressure distribution even again, and the demoulding easily, core rod does not need to adopt multistage to connect when producing many bellowss, therefore the problem that has not only solved the easy extrusion fracture of enhancement layer in the production of existing in prior technology silicon rubber sebific duct and be difficult to the demoulding, and it is good that the product of producing has outward appearance, inner wall smooth (no burr, burr), section is even, enhancement layer is neat and orderly, enhancement layer and silicon rubber adhesive strength height, anti-advantage such as subdue.

Label declaration:
Existing technology: 1 core rod, 2 core rod seams, 3 sebific duct blanks, 4 upper and lower moulds, 5 sebific duct products, 6 burr or burr;
Technology of the present invention: 7 capsules, the interior pressure tube connector of 8 capsules, 9 sebific duct blanks, 10 moulds, 11 sebific duct products.
The specific embodiment
The embodiment of the invention is characterised in that, it is characterized in that, its processing step is as follows:
A. straight forming sebific duct blank on the surface of the capsule 7 that adapts with sebific duct 11 internal diameters;
B. the sebific duct blank 9 of forming is put into mould 10 die cavitys together with capsule;
C. matched moulds is squeezed into interior pressure to capsule, vulcanizes;
D. sulfuration is finished, and capsule is extracted in release, obtains sebific duct.
Because sebific duct has certain shrinkage in preparation process, therefore the external diameter of described capsule should be slightly less than the internal diameter of sebific duct.
Described core rod is a capsule.
Not only technology is simple, easy to operate in the present invention, production efficiency is high, and the product appearance of producing is good, inner wall smooth (no burr, burr), section is even, enhancement layer is neat and orderly, enhancement layer and silicon rubber adhesive strength height, anti-subduing.The silicon rubber sebific duct of explained hereafter of the present invention is mainly used in Diesel engine and uses Diesel engine flexibly connecting as the water flowing of the automobile of power, engineering machinery, steam pipe road.
