Description
Technical field
The utility model relates to a kind of reusable GRC mould, particularly relates to a kind of vacuum forming quick shaping process of reusable GRC mould.
Background technology
Glass fiber reinforced cement (GRC) take alkali-resistant glass fibre as reinforcing material, cement is a kind of composite that Binder Materials matrix is formed, give prominence to its high-strength light, decorative effect, be easy to build the characteristics such as polymorphic structure, application in building curtain wall ornament materials obtains a very wide range of concern, meets the application demand of modern architecture exterior wall.The strong plasticity of GRC gives building designers more wide free writing space, for creationary architectural design provides feasible way, thus according to architectural design needs, can mould various profile; Groove, broken line can be selected arbitrarily in architectural design to change or various curve modeling; Both may be used for the decoration of classicism building, may be used for again going along with sb. to guard him of smartness building.In addition, GRC also by a large amount of among Landscape Design, build various unusual decoration and the view with different shaping, as fountain, flowerpot, resting chair decoration etc.
Although GRC can realize the manufacture of Complex Different Shape structure, depend critically upon the preparation of mould in the production of GRC, GRC mould plays vital effect in well shaping, the excellent artistic expression of goods.Not only to prepare the mould of original size, form in production, and have higher requirement to the surface of mould.Die surface must be guaranteed smooth, smooth, indefectible, surface layer just can be made to prepare evenly, form uniform texture finishes when later stage GRC surface layer process.Traditional moulds mainly adopts in producing and comprises fiber reinforced plastic mold, silica gel mould, gypsum mold etc., especially for complex component mould, needs the human and material resources resource of at substantial.The mould preparation work cycle is long, seriously constrains quick production and the cost control of GRC.On the other hand, for special-shaped GRC component, the repeatability of mould is poor, causes the scrappage of mould high; The mould adopting the material such as fiberglass, silica gel to produce is difficult to the cycling and reutilization realizing material, just becomes building waste, not only how to process the production problem that mould becomes serious, and consume a large amount of materials and equipment resources after completing GRC production.How fast preparation can meet Production requirement and reusable mould, is the key technology of GRC cleaner production.
In model manufacturing, molding sand, paraffin or clay are that a class is reusable, and than being easier to moulding material, can meet reusable object.But, molding sand model surface not easily sanding and polishing, and paraffin, the polishing of clay model surface need to consume a large amount of man-hours.Therefore, such material can not form effective smooth die surface fast, to meet the production of GRC.In quick shaping process, thermoplastic sheets can form the goods of given shape fast by vacuum forming technology, and high, the smooth zero defect of surface smoothness.Prior, thermoplastic sheets after shaping pulverize after can more again mixing extrusion obtain the plastic uptake sheet material that recycles.
Summary of the invention
The utility model object is for above-mentioned weak point, a kind of vacuum forming is provided to prepare the GRC mould that can be recycled fast, prepare gas permeability pattern and modify with thermoplastic sheet vacuum forming accelerated surface the forming method combined easily to mould, can be recycled material specifically, realize GRC mould molding fast, can be recycled.
Vacuum forming prepares the GRC mould that can be recycled fast, comprises GRC pattern and surface layer decorative layer, and surface layer decorative layer is covered in GRC pattern surface;
GRC swage inside described in the utility model has gas permeability duct, coordinates vacuumize process to pattern with pump-line;
Plastic uptake sheet material stretching is pasted, shapes at pattern on the surface by vacuum forming technology by the decorative layer of surface layer described in the utility model.
