Abstract
A ceramic moulding technology with ethyl silicate and self-hardening sand features lower powder/liquid ratio, that is, the ratio of refractory to hydrolyzed liuqid of ethyl silicate is lower than that used in existing techniques. The moulding process includes directly attaching ceramic to mould, adding water glass and sand, shaping and demoulding. Its advantages are simple process, low cost, and high productivity and quality of casting.
Description
The invention belongs to casting technique, be specifically related to ceramic precision casting technology.
The ceramic mould precision process is all used the Shore grouting method both at home and abroad at present.This method is to give using alcohol prepare silicon hydrolysis of ethyl acetate liquid earlier, prepare slurry again, and paste layer is made the sand cover on model, at last grouting.Go back GPRS gum deposit " young plant " during grouting, casting mold also needs torch firing and fuses.Technology is tediously long, complexity, and in only being applicable to, the production of smallclothes.(the organic solvent-free mixed hydrolysis casting technique that N86100313 proposes, powder liquor ratio are 100 grams: 25 milliliters-100 grams: 36 milliliters, when making ceramic mould, need to adopt slurry molding, and consumption is big.
The objective of the invention is to based on CN86100313, propose low powder liquor ratio, adopt and directly on model, adhere to ceramic mould, to overcome above-mentioned water foot.
For realizing the object of the invention, following scheme is proposed, technology comprises batching, moulding and casting mold drying.Wherein the proportioning of refractory material and silicate hydrolyzate liquid is 100 grams in the blending process: 14 milliliters-100 grams: 22 milliliters.Modeling process, with the preparation the silester compound be powder liquid compound directly in the attached one deck ceramic mould of model surface, treat its sclerosisization after, hold glass sand moulding molding its back side Chinese toon and get final product.Modeling process can realize finishing the superthin layer ceramic mould.
This technology has following advantage than prior art:
1, simplified technological process.Shorten the production cycle, improve work efficiency.And the processing ease of similar common sand mold is grasped.
2, owing to make the superthin layer ceramic mould earlier, back Chinese toon water-glass sand helps these two and combines closely.
What 3, make is the superthin layer ceramic mould, so casting mold body contraction distortion amount is little, has reduced the generation of crackle greatly, has improved casting quality.
4, the liquid consumption significantly reduces, and ceramic mould is attenuate greatly again, and production cost is low, than phenolic sand molding economy.
5, modeling process is not subjected to time restriction, can carry out intermittently, therefore is particularly suitable for making the ceramic mould of especially big piece.

Embodiment:
Select different refractory materials for use according to different metal castings, it comprises quartz, mullite, zirconium English and corundum.Silicate hydrolyzate liquid comprises that silicic acid second is joined, water, hydrochloric acid, adopts different refractory materials, and proportion of composing is also different in the silicate hydrolyzate liquid, specifically as shown in Table 1:
Its process for preparation is as shown in Figure 1: promptly earlier refractory material and silester are puddled evenly, added acidifying water again and mix, add industrial magnesium oxide rapidly.Stand-by.
Moulding is as shown in Figure 2: in the thick ceramic mould 2 of surperficial attached one deck 4-6mm of model 1, oneself prepares ceramic moulding mixture 2 above-mentioned.Adherence method is as the cement mud wall.Treat ceramic mould 2, after the sclerosis, at its back side Chinese toon water-glass sand 3, blow carbon dioxide, moulding 4 is promptly finished in molding after the moulding.
Mould drying:
Because what make is the ceramic mould of superthin layer, mould drying is just fairly simple, and it does not need very high temperature to carry out roasting.For the enterprise that does not possess drying plant, the even torch firing of available oxygen welding gun gets final product, if dry its stoving process such as Fig. 3.
