Abstract
The invention relates to the field of manufacturing of dies, in particular to an autoclave die for improving the surface quality of a workpiece and a method. The autoclave die for improving the surface quality of the workpiece comprises a die body, a frame, a pressing plate, a pressing block, a demoulding bolt and a fastening bolt, wherein an annular groove is formed in the periphery of the workpiece on the die body, and the frame is embedded in the annular groove and provided with a demoulding bolt hole and a fastening bolt hole. According to the autoclave die, the die body guarantees the inner surface quality of the workpiece, and the frame, the pressing plate and the pressing block guarantee the outer surface quality of the workpiece. Accordingly, the autoclave die guarantees the roughness of the inner and outer surfaces of the workpiece and is simple in structure and low in cost.
Description
Technical field
The present invention relates to Mold Making field, specifically, is a kind of autoclave mould and method of improving article surface quality.
Background technology
Mould, in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press obtains required product, in brief, mould is used to the instrument of formed article, this instrument is made up of various part, different moulds is made up of different parts, and it realizes the processing of article profile mainly through the change of institute's moulding material physical state.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank be separated (stamping-out) by outline line shape.Application cavity shape can make blank obtain corresponding three-dimensional shape.
Autoclave forming process refers to puts into autoclave with vacuum bag sealed composite material blank combination part, under the condition of heating, pressurization, be cured the shaping a kind of process preparing composite product.
When utilizing autoclave technological forming product, general mould is one side mould, can only ensure the surface quality in pad pasting face, and outer surface requires that smooth product commonly uses former, otherwise, then use formpiston.And the product one side of some autoclave molding is fitting surface, another side is appearance, and the surface quality on two sides all requires higher.
Summary of the invention
The object of this invention is to provide a kind of autoclave mould improving product surfaces externally and internally quality, solve the problem of non-pad pasting face surface quality difference in prior art.The technical scheme that the present invention discloses is a kind of autoclave mould improving article surface quality, comprise die main body, frame, stripper bolt, fastening bolt, rectangular die main body arranges cannelure around accommodation product position, cannelure is embedded with two frames, some stripper bolt holes and fastening bolt holes is provided with in frame, also comprise rectangle pressing plate, pressing plate is arranged at the inner circumference of cannelure to sealing function, pressing plate is also provided with some briquettings, briquetting centre position is provided with screwed hole, is provided with stripper bolt in screwed hole.
Further improvement of the present invention, pressing plate adopts steel plate to make, and the thickness of pressing plate is 1-5mm, is preferably 2mm.
Specific embodiment of the invention step, product surfaces externally and internally quality can be improved: use above-mentioned autoclave mould, first assemble die main body, frame, then prepreg is laid, successively by briquetting after laying completes, platen cover is at prepreg upper surface, put airfelt etc. again and beat vacuum bag, mould is moved to autoclave be cured, curing and demolding, demoulding order is: the fastening bolt first dismantling frame, then the stripper bolt on frame is utilized to be deviate from by frame, utilize the stripper bolt on briquetting to apply knockout press briquetting is taken out, take away pressing plate again, finally by product break away from moulds main body.
Beneficial effect of the present invention: the present invention is a kind of autoclave mould improving product surfaces externally and internally quality, adopts pressing plate and briquetting to ensure the surface quality of outer surface, utilizes simple mould structure to solve the ropy problem in traditional moulds non-pad pasting face.
