According to the manufacturing mold disclosed by the utility model, the arc-shaped pipe is integrally manufactured and molded by utilizing thermal expansion properties of the silica gel stick and an external sizing function of a glass mold. The manufacturing mold disclosed by the utility model has the positive effects that the operation steps are simple, a product has a good-looking appearance and the high intensity, the structural performance is good, the arc shape error is small, and the work efficiency is high.
Description
Technical field
The utility model belongs to composite production technical field, is specifically related to a kind of making mould of composite curved pipe.
Background technology
The method of blowing bag is mainly used in the making of curved pipe in the market, and its preparation method is first to make soft bag, and guarantees that soft bag is air tight, by the pre-atmosphere of soft bag, then material is wrapped on soft bag, and places it in mould, after matched moulds again to inflating increase pressure in soft bag.The shortcoming of this method is that program is many, and the pressure of air is inadequate, and product strength is low, and the inner surface of pipe has fold rough, and structural behaviour is low.And blowing bag method makes mould used and mostly be metal die, die cost is high, and large-scale curved pipe mould cannot be made.
Summary of the invention
The purpose of this utility model is to provide a kind of making mould of composite curved pipe, to solve the problems of the technologies described above.
The making mould of composite curved pipe described in the utility model is mainly comprised of fiberglass mold, fiberglass bed die, bolt, the technical scheme that solves its technical problem employing is that fiberglass mold and fiberglass bed die are semicircle, adopts bolt to fix; Between fiberglass mold and fiberglass bed die, silica gel stick is set, silica gel stick is cylindrical, and external diameter is than the little 1.5-2mm of the internal diameter of curved pipe, and length is greater than curved pipe length 180-220mm; Between fiberglass mold, fiberglass bed die and silica gel stick, form dies cavity, dies cavity diameter is curved pipe external diameter, and length is greater than silica gel stick length 18-22mm.
Preferably, the thermal coefficient of expansion of described silica gel stick is 2%-3%.
The main material that composite curved pipe described in the utility model is made is prepreg, prepreg is with resin matrix impregnating continuous fibres or fabric under the strict condition of controlling, making the composition of resin matrix and reinforcement, is the material of manufacturing composite products.
The utility model utilizes hot expansibility and the outer shapping function of glass mold of silica gel stick, by the moulding of curved pipe integral manufacturing.Adopting good effect of the present utility model is that operating procedure is simple, and product design is attractive in appearance, and product strength is high, and structural behaviour is strong, and arc error is little, and operating efficiency is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the structural representation of the making mould of composite curved pipe described in the utility model;
1 fiberglass mold, 2 dies cavities, 3 bolts, 4 fiberglass bed dies, 5 silica gel sticks in figure.
The specific embodiment
As shown in Figure 1: fiberglass mold 1 and fiberglass bed die 4 are semicircle, adopt bolt 3 fixing; Between fiberglass mold 1 and fiberglass bed die 4, silica gel stick 5 is set, silica gel stick 5 is cylindrical, and external diameter is than the little 1.5-2mm of the internal diameter of curved pipe, and length is greater than curved pipe length 180-220mm; Between fiberglass mold 1, fiberglass bed die 4 and silica gel stick 5, form dies cavity 2, dies cavity 2 diameters are curved pipe external diameter, and length is greater than silica gel stick 5 length 18-22mm.
Adopt the method for above-mentioned Mold Making composite curved pipe: prepreg material webs, on silica gel stick 5, is guaranteed to compacting between prepreg material layer in the process of volume; After be placed in fiberglass bed die 4, fiberglass mold 1 matched moulds is on fiberglass bed die 4, fastening with bolt 3, heat, curing molding, the demoulding, takes out silica gel stick 5, curved pipe completes.
Concrete preparation method is as follows:
1, make silica gel stick 5: according to the internal diameter of curved pipe, make silica gel stick 5, the external diameter of silica gel stick 5 requires than the little 1.5-2mm of the internal diameter of curved pipe, the thermal coefficient of expansion of silica gel stick 5 is 2%-3%, and the length of silica gel stick 5 is greater than curved pipe length 180-220mm, so that silica gel stick takes out.
2, adopt VARI technique, fiberglass mold 1 and fiberglass bed die 4 complete respectively: fiberglass mold 1 and fiberglass bed die 4 are semicircle, adopt bolt 3 fixing, between fiberglass mold 1, fiberglass bed die 4 and silica gel stick 5, form dies cavity 2; Dies cavity 2 diameters are curved pipe external diameter, and length is greater than silica gel stick 5 length 18-22mm.
3, moulding: according to design laying thickness by prepreg material webs on silica gel stick 5, in the process of volume, guarantee compacting between prepreg material layer; After be placed in fiberglass bed die 4, fiberglass mold 1 matched moulds is on fiberglass bed die 4, fastening with bolt 3, according to the composition of prepreg, determine that heating schedule heats, curing molding, the demoulding, takes out silica gel stick 5, curved pipe completes.
Claims (2)
