Abstract
The utility model discloses a kind of mold heating device, comprise heating plate and the reflecting plate being fixed on heating plate surrounding; Described reflecting plate is even width and end to end stripe board in the form of a ring; Mold heating device of the present utility model, the reflecting plate of its ring-type contact mould is made mould, forms closed heating chamber between heating plate and reflecting plate, for heating fiberglass wind power cabin cover mould, and then make heat be passed to die cavity, keep the temperature of resin adhesive liquid in die cavity, guarantee compactedness and forming quality of products, in heating process, heat-energy losses is less.
Description
Technical field
The utility model relates to heater, particularly relates to a kind of mold heating device.
Background technology
When adopting resin transfer molding (RTM) process to carry out processing wind power engine room cover, resin adhesive liquid needs flowing in narrow and small die cavity and is full of die cavity gradually, final curing is shaping, resin adhesive liquid is emulsion liquid, viscosity is large, the mobility of the reduction resin adhesive liquid along with temperature in filling process is deteriorated gradually, affects compactedness, cannot ensure forming quality of products.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of mold heating device, for heating fiberglass wind power cabin cover mould, and then makes heat be passed to die cavity, keeps the temperature of resin adhesive liquid in die cavity, guarantees compactedness and forming quality of products.
Mold heating device of the present utility model, comprises heating plate and the reflecting plate being fixed on heating plate surrounding; Described reflecting plate is even width and end to end stripe board in the form of a ring;
Further, described reflecting plate is arranged between reflecting plate and heating plate in obtuse angle in the side of heating plate;
Further, described heating plate and reflecting plate are flexibility;
Further, described heating plate is also fixed with warming plate; Described warming plate is fixed on the opposite side of heating plate relative to reflecting plate, and warming plate covers the whole side of heating plate;
Further, described warming plate is cystosepiment.
The beneficial effects of the utility model are: mold heating device of the present utility model, the reflecting plate of its ring-type contact mould is made mould, forms closed heating chamber between heating plate and reflecting plate, for heating fiberglass wind power cabin cover mould, and then make heat be passed to die cavity, keep the temperature of resin adhesive liquid in die cavity, guarantee compactedness and forming quality of products, in heating process, heat-energy losses is less.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure: the mold heating device of the present embodiment, comprises heating plate 1 and the reflecting plate 2 being fixed on heating plate 1 surrounding, described reflecting plate 2 is even width and end to end stripe board in the form of a ring, heating plate 1 can be electrothermal structure, comprise high-temperature insulation substrate and the heating wire being layed in substrate surface, by producing heat to heating wire energising, heating plate 1 also can be the high temperature resistant plate being provided with air intake duct and return-air road, the cavity that air intake duct and return-air road all surround with reflecting plate 2 and heating plate 1 communicates, therefore mould is heated constantly passing into thermal current in air intake duct by carrying out heat exchange between thermal current and mould, and the air-flow after heat exchange flows out along return-air road, circulation like this is heated mould, mould, closed heating chamber is formed between heating plate 1 and reflecting plate 2, heat-energy losses is less, be adhesively fixed between reflecting plate 2 and heating plate 1.
In the present embodiment, described reflecting plate 2 is in the side of heating plate 1 and arrange in obtuse angle between reflecting plate 2 and heating plate 1, is held in mold surface energy and forms stable annular seal space, be convenient to the installation of heater and make stable connection between heater and mould.
In the present embodiment, described heating plate 1 and reflecting plate 2 are flexibility, die surface structure can be adapted to, applicability is good, utilize the distortion of reflecting plate 2 and rebound performance to improve mould simultaneously, the sealing of the heating chamber formed between heating plate 1 and reflecting plate 2, outer edge along reflecting plate 2 is provided with the groove of annular, reflecting plate 2 is made to be fastened on mould by this groove, form sucker structure, extrude reflecting plate 2 along the direction on vertical mold surface when therefore installing and the air in this groove is extruded, make to form vacuum in this groove, negative pressure of vacuum effect is utilized to make reflecting plate 2 be fixed on die surface, and ensure the sealing between reflecting plate 2 and mould.
In the present embodiment, described heating plate 1 is also fixed with warming plate 3; Described warming plate 3 is fixed on the opposite side of heating plate 1 relative to reflecting plate 2, warming plate 3 covers the whole side of heating plate 1; Warming plate 3 can not only play heat insulation effect, reduce thermal loss, and can play certain reinforcement effect to heating plate 1, is convenient to the use of heater, and warming plate 3 and heating plate 1 surface are adhesively fixed.
In the present embodiment, described warming plate 3 is cystosepiment, and cystosepiment not only quality is light, easy to use, and cost is low.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
