Abstract
The invention shows a method of producing grinding pencil wheel in vacuo and its mould. It pumps the air, covers top sheet, fills sand, tamp it, covers backing film, pumps the air and gets the moulds, lower model and upper model of the grinding pencil wheel. Then it closes the mould and forms the cavity of the mould. Finally, it pours it into shape, cools it and gets the intact mould. The invention's advantages lie in: the method of producing grinding pencil wheel in vacuo can increases the work efficiency greatly; the work efficiency of the single cargo is increased by scores of times; the manufacturing rate reaches 95%; the defective index is decreased greatly and can realize the mechanized production. The mould of the grinding pencil wheel is featured by reasonable construction and simple operation.
Description
Technical field
The present invention relates to produce the method for abrading-ball, is that the abrading-ball method is produced in a kind of vacuum seal, and it is specially adapted to produce the abrading-ball that ball mill is used.
Background technology
The existing abrading-ball method of producing mainly adopts forming methods such as metal mold, tide mould sand moulding.Tide mould sand moulding and metal mold only can be produced 3-5 ball one the case, and main process is manually-operated, and product yield is below 70%, and input personnel are many, and the technical process controllability is relatively poor, the labour intensity height, and production efficiency is low, the percent defective height.
Summary of the invention

In like manner, at first abrading-ball upper mould case is bled, next is at the die face clad can film of abrading-ball upper mould case, then abrading-ball frock top box is placed on the abrading-ball upper mould case, back-up sand and carry out jolt ramming in abrading-ball frock top box, cover notacoria and bleed at the abrading-ball frock top box face of jolt ramming, last molding obtains model on the abrading-ball;
Second step, above-mentioned abrading-ball frock nowel and the above-mentioned abrading-ball frock top box that makes model on the abrading-ball that makes the abrading-ball drag carried out mould assembling, form the abrading-ball model cavity;
In the 3rd step, carry out the abrading-ball that moulding by casting, cooling, molding obtain moulding.
The film that can cover needs earlier before above-mentioned clad can film or notacoria heats.
The face temperature of above-mentioned heating is controlled at 50 ℃ to 80 ℃.
Two of technical scheme of the present invention is that a kind of abrading-ball mould that is used for vacuum seal production abrading-ball method is achieved like this: this abrading-ball mould can comprise abrading-ball lower mould case, abrading-ball upper mould case and abrading-ball frock case;
Above-mentioned abrading-ball lower mould case comprises the counterdie casing, in the front of counterdie casing abrading-ball counterdie, ingate and well are arranged, the front of counterdie casing have with the counterdie casing in the passage that communicates, the side of counterdie casing or bottom surface have with the counterdie casing in the exhaust tube that communicates.
Outer side surface at above-mentioned counterdie casing can be useful on the self-clinching of location or/and dowel hole.
Above-mentioned abrading-ball upper mould case comprises the patrix casing, abrading-ball patrix, ingate, main cross gate are arranged in the front of patrix casing and pay cross gate, the front of patrix casing have with the patrix casing in the passage that communicates, the side of patrix casing or bottom surface have with the patrix casing in the exhaust tube that communicates.
Outer side surface at above-mentioned patrix casing is useful on the self-clinching of location or/and dowel hole.
Above-mentioned abrading-ball frock case comprises abrading-ball frock nowel and abrading-ball frock top box, is useful on the breather line of bleeding in the frock casing, and passage is arranged on breather line, and there is the exhaust tube that communicates with breather line the side of frock casing.
On above-mentioned breather line, can have and to prevent that sand is inhaled into the screen pack of breather line.
Can there be hangers the side of above-mentioned frock casing or/and buckle.
Characteristics of the present invention are: the abrading-ball method is produced in this vacuum seal can increase substantially production efficiency, and single case production efficiency is carried tens of times, and product yield reaches 95%, and percent defective reduces significantly, also can realize mechanization production; This abrading-ball forming die structure rationally, the advantage being convenient to operate.
