Abstract
The present invention discloses a mold for producing hot melt glass and a method for making the mold. The mold for producing hot melt glass comprises a forming surface by which the hot melt glass can be formed; the mold is made by firing a ceramic blank, with AL2O3 contained more than 20%. The method for making the mold comprises: a steel mold is made firstly; then the steel mold is used as a mother plate, and a plurality of ceramic blank plates are made by firing according to a method for producing ceramic; the mold for producing hot melt glass can be obtained after paint for improving smoothness is sprayed on the surfaces of the ceramic blank plates. Compared with the steel mold, the mold for producing hot melt glass of the present invention has the advantages of low cost, easy processing, lightness, rapid heat radiation during producing, small deformation of products, high rate of finished products, possibility of recycling and favorableness for mass production.
Description
Technical field
The present invention relates to a kind of manufacture method of production mould and this mould of hot melt glass.
Background technology
The mould that the hot melt glass technological process of production of the prior art adopts all is the mould that iron and steel is made, technical process mainly be with sheet glass open be situated between into suitable specification after, lie on the mould made from iron and steel, put into again and heat in the electric heating stove to glass remollescent temperature, make the softening back of glass by the pattern of mould natural shaped after, the You electric heating stove is lowered the temperature naturally again, and whole process of production needs 7-8 hour.Because the cost of steel mold is higher, and use the electric heating stove temperature difference big, yield poorly, product quality guarantees that not enough the harvest rate is again low, and is both consuming time, and power consumption is big again, and production cost is higher, lacks competitiveness in market.And when adopting the steel die of prior art not only since its weight can't in roller kilns, use too greatly, simultaneously its heat radiation time longer, several steel mold are arranged in to be used in the roller kilns, its cost is high.
Summary of the invention
The object of the present invention is to provide that a kind of cost is low, the yield rate height of product, save energy and reduce the cost, increase income and economize on spending, and the manufacture method of the mfg. moulding die of a kind of hot melt glass that can be mass-produced and this mould.
The present invention realizes above-mentioned purpose by following proposal: the mfg. moulding die of hot melt glass of the present invention comprises a forming face that hot melt glass is shaped, and this mould is fired by ceramic blank and made, its AL
2O
3Content more than 20%.
The present invention realizes above-mentioned purpose by following method: the manufacture method of the production mould of hot melt glass of the present invention is, at first makes a steel die, then take this steel die as motherboard, utilizes AL according to the method for producing pottery
2O
3Content burns out some ceramic blank daughter boards at the ceramic blank raw material more than 20%, and adds spray on its surface and can improve bright and clean coating, namely gets described hot melt glass production mould.
The invention has the advantages that: be ceramic mold tool because the hot melt glass of tradition use originally steel die is used instead, replaced steel die cost height, heaviness, dispelled the heat slowly in process of production, both consuming time, power consumption is big again, and influences the backward phenomenon of quality product, the ceramic mold tool that replaces, cost is low, easily processing, light and handy and rapid heat dissipation, product distortion are little in process of production, harvest rate height, and can circulate and repeatedly use.
Owing to adopt the ceramic blank mould to replace steel mold, thereby the process of producing the hot melt glass product also can correspondingly be improved, on the mode of the production of original traditional Yun Yong electric heating stove, reform and innovation are for using the roller kilns production of combustion gas, the production advantage of roller kilns is: can produce uninterruptedly, furnace temperature is controlled automatically, product is from advancing stove, heat up, cool to product and come out of the stove, the overall process temperature can be controlled automatically, and the production process of every stove product only needs 80-120 minute, and production efficiency height, the output of product is big, and quality is good, and the harvest rate can reach more than 98%, not only energy-conservation but also lower consumption, reach the purpose of increasing income and economizing on spending.
Specific embodiment
The mfg. moulding die of hot melt glass of the present invention comprises a fish shape forming face that hot melt glass is shaped, and this mould is to be fired by ceramic blank to make its AL
2O
3Content more than 20%, purpose is for the hardness that improves it and resistant to elevated temperatures characteristic.
The manufacture method of the mfg. moulding die of hot melt glass of the present invention is as follows: at first, require to make a steel die according to Production design, then take this steel die as motherboard, burn out some ceramic blank daughter boards according to the method for producing ceramic, the material that adds exotic material and the ceramic porcelain base hardness of enhancing before firing in the ceramic blank raw material is such as the AL more than 20%
2O
3, add spray on its surface at last and can improve bright and clean coating, namely get described hot melt glass production mould.
During practical application, not re-using steel die of the prior art is that template is produced glass, but directly uses the mfg. moulding die of hot melt glass of the present invention to produce glass as template; Do not re-use the mode of production of electric heating stove formula of the prior art yet, but improved on this basis, use the production of combustion type roller kiln; Lie on the mfg. moulding die of hot melt glass of the present invention opening the good required specification glass that is situated between, it is put into roller kiln, in roller kiln, heat, lower the temperature, promptly get the hot melt glass finished product after coming out of the stove, above whole process needs 80-120 minute, and the whole process temperature is automatic control.
Claims (2)
1, a kind of production mould of hot melt glass comprises a forming face that hot melt glass is shaped, and it is characterized in that this mould is fired by ceramic blank and formed, its AL
