Abstract
The invention discloses a press molding technological process which comprises the following steps of material preparation, manufacture of powder and ingredients, powder modification, wax melting, press die entering, rapid heating, demolding, appropriate repairing of a green body and hot braising. The press molding technological process is high in molding size accuracy, almost free of subsequent process, short in molding time and high in production efficiency. Compared with other ceramic molding technology, production cost is relative low, and requirements for production equipment and operating environment are not high.
Description
Technical field
The present invention relates to a kind of press-molding technological process.
Background technology
At present, pottery is seen everywhere in living environment, the technique of Production of Ceramics also constantly updates, mostly adopt the method for compression molding to prepare ceramic articles for use, the weak point of compression molding is that the mould manufacturing is complicated, invest greatlyr, add limited by press, be best suited for the middle-size and small-size composite product of batch production.Updating and develop along with metalworking technology, press manufacture level and synthetic resin processing performance, press tonnage and mesa dimensions constantly increase, the forming temperature of molding compound and pressure is relative reduce also, so that the size of compression molding goods is progressively to large scale development, provide the technological forming time short in the urgent need to us, production efficiency is high; Compare other ceramic molding, production cost is relatively low, to production equipment and the less demanding ceramic preparation technology of operating environment.
Summary of the invention
For the problems referred to above, the invention provides that a kind of automation is complete, ask the press-molding technological process short, that production efficiency is high during technological forming.
Technical scheme of the present invention is as follows:
A kind of press-molding technological process comprises the steps:
(1) gets the raw materials ready, purchase the versicolor ceramic material for the production of the ceramic articles for use of preparation;
(2) be processed into powder and batching, the material of selecting by being machined into powder and carrying out mix according to proper proportion;
(3) powder modification adds surface modifier in the ceramic powder;
(4) melt wax, the powder after the modification is added mix in the paraffin of fusing to evenly;
(5) press enters mould, and the powder that just proportioning is good adds in the hot die-casting molding machine, and heating adds pressure injection
Enter mould molding;
(6) Quick-pressing;
(7) demoulding and base substrate suitably repaired;
(8) heat is stewing, under the condition of secluding air, will carry out scorching hot through the demoulding and trimmed base substrate.
Proper proportion refers to the ratio of different colours powder described in the step (2), regulates and control to realize by intelligence control system.
Modifier is oleic acid, stearic acid etc. described in the step (3), make it to have lipophile, and wax liquid merges well.
Be provided with apparatus for distributing in the mould described in the step (5), make the ceramic articles for use with required pattern, pattern by apparatus for distributing.
Press-molding technological process provided by the invention possesses following advantage:
Plastic complex-shaped ceramic, dimensional accuracy is high, needs hardly following process; Molding time is short, and production efficiency is high; Compare other ceramic molding, production cost is relatively low, and is less demanding to production equipment and operating environment; Strong to adaptability to raw materials, all applicable such as oxide, non-oxidized substance, compound material and various raw mineral materials.
The specific embodiment
A kind of press-molding technological process comprises the steps:
(1) gets the raw materials ready, purchase the versicolor ceramic material for the production of the ceramic articles for use of preparation;
(2) be processed into powder and batching, the material of selecting by being machined into powder and carrying out mix according to proper proportion;
(3) powder modification adds surface modifier in the ceramic powder;
(4) melt wax, the powder after the modification is added mix in the paraffin of fusing to evenly;
(5) press enters mould, and the powder that just proportioning is good adds in the hot die-casting molding machine, and mould molding is injected in the pressurization of heating;
(6) Quick-pressing;
(7) demoulding and base substrate suitably repaired;
(8) heat is stewing, under the condition of secluding air, will carry out scorching hot through the demoulding and trimmed base substrate.
Proper proportion refers to the ratio of different colours powder described in the step (2), regulates and control to realize by intelligence control system.
Modifier is oleic acid, stearic acid etc. described in the step (3), make it to have lipophile, and wax liquid merges well.
Be provided with apparatus for distributing in the mould described in the step (5), make the ceramic articles for use with required pattern, pattern by apparatus for distributing.
