Description
Technical field
The present invention relates to mould manufacturing field, relate in particular to a kind of preparation method of five-pointed star mould.
Background technology
Mould, in industrial production in order to injection moulding, blowing, extrude, various moulds and instrument that the method such as die casting or forging forming, smelting, punching press obtains required product.In brief, mould is the instrument for formed article, and this instrument is made up of various parts, and different moulds is made up of different parts.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.Have the title of " mother of industry ".The research of existing five-pointed star mould is few, and production technology is perfect not, has all problems.Based on this, the preparation method of studying a kind of perfect five-pointed star mould seems especially important.
Summary of the invention
In order to overcome the defect of above-mentioned prior art existence, the invention provides the preparation method of the five-pointed star mould that a kind of operating condition is simple, perfect.
Technical problem solved by the invention can adopt following technical scheme to realize:
A preparation method for five-pointed star mould, is characterized in that, comprises following sequential steps:
(1) size as required, on a formation plate, uses mechanical drawing method, draws the figure of a five-pointed star;
(2) in the center of five-pointed star, the thin stick of a perpendicular desired height;
(3) mould a three-dimensional five-pointed star with sculpture clay or plasticine by the figure of five-pointed star, the summit that should note wooden stick while moulding and most advanced and sophisticated five ribs that are connected of five-pointed star, to form ten faces maintenances of these five ribs smooth and be in line;
(4) with harder paperboard or veneer, enclose wall in the surrounding of five-pointed star apart from the place of 1-2 centimetre, make gypsum be limited in this scope, unlikely loss waste.Simultaneously can be according to designing requirement, make gypsum condense into the plaster block of various shapes;
(5) stir gypsum, general available enameled basin and enamel bowl.Land plaster is sprinkled in water equably, until land plaster and water is when substantially equal, spreading land plaster must be rapidly evenly, must wait again land plaster all after permeable point of suctions, could stir otherwise easily produce pimple after spreading.When stirring, as use is little bowl, as long as just can with two fingers, as use is washbasin, support and use to and fro exhausted stirring with the whole hand that struts the five fingers, calcium plaster must be after abundant stirring toughness, the calcium plaster being stirred, some foams are often floating on surface, must manage to remove, otherwise the surface of mould will leave pore that foam produces, affect the bright and clean of mould and the finished product of casting out, and process must make the best use of time, make the lower step Production Time can be more abundant, and shorten the time of making, because the setting time after land plaster and water are met is conditional,
(6) by the land plaster being stirred, pour into lightly above a part of five-pointed star, make it own to current downflow, do not have mobile place, can fall again some calcium plasters, or touch lightly with pointing, calcium plaster is flooded whole five-pointed star, also note not leaving air in calcium plaster, then at leisure calcium plaster is poured into gently in " enclosure wall ", and the mould equally high, small-sized like this with " enclosure wall ", general alone gypsum is just passable; As its fastness of need increase, can add some cement, but must, with more than No. 500, in ratio, be no more than 30 percent, large-scale mould also need to add some lead bullion silks or reinforcing bar and flax silk in the middle of mould, to increase intensity and the pulling force of mould;
(7) through about 15-20 minute, when gypsum a bit warm, gypsum reach due hardness time, mud is cut out, can obtain five-pointed star mould.
Preferably, in described step (4), the distance of the surrounding of optimum distance five-pointed star is 1.5cm.
Preferably, in described step (7), Best Times is 18 minutes.
Beneficial effect of the present invention is: simple in production process operation of the present invention, perfect, rationally control various reaction time and condition well in the process of making, and the five-pointed star mould and die accuracy of producing in the time reaching optimum is higher, is widely used in various machinery production processing.
Detailed description of the invention
Below in conjunction with specific embodiment, technical scheme of the present invention is further described in detail:
