Tin inlay mold and method for producing tin inlay technique pattern

Abstract

The invention relates to a method for producing handicraft articles, in particular to a method for manufacturing a tin-embedded die and a tin-embedded technological pattern. The tin-embedded die is made of silica gel. The step for manufacturing the tin-embedded technological pattern comprises the following steps: manufacturing a stone die, engraving the stone die according to layout work, and arranging a liquid casting flow passage; melting passivated tin into a tin liquid; injecting the tin liquid into the stone die, and taking out a pattern after solidification; removing redundant parts of the pattern, and using sand paper to grind the surface of the pattern; manufacturing a master die; manufacturing a silica gel die blank; placing the master die on the surface of the silica gel die blank, and placing the silica gel die blank on a press molding machine for heating and compression molding; taking out the master die from a silica gel die after cooling, and obtaining the silica gel die; melting passivated tin into a tin liquid; and injecting the tin liquid into the silica gel die, taking out the pattern after the tin liquid is solidified, and obtaining the tin-embedded technological pattern after edging. The method has the advantages that due to adoption of the silica gel die, the finely chiseled master die can be preserved and used permanently after compression molding; die turnover for a plurality of times is not required; and the method can meet the requirements of scale and industrialization of the handicraft articles.

Description

Technical field: [0001] The invention relates to a production method of handicrafts, in particular to a tin-inlaid mold and a method for making tin-inlaid technical patterns. Background technique: [0002] As we all know, tin inlay crafts and tin inlay crafts were created at the end of the 19th century. The founder of tin inlay crafts, Gu Nianhe, was born in Gujiatuan, Weihai City, Shandong Province. ), due to wars and social turmoil over the years, the tin inlay technology was almost lost. After the reform and opening up, Gu Zuwei, the grandson of Gu Nianhe, excavated and sorted out the secret recipes, stone molds and production utensils kept at home and put them into production. This tradition Craft products have sprung up like bamboo shoots after rain and developed rapidly, forming factory production and registering the "Xinhecheng" brand trademark. [0003] The first step of the tin inlay process is to make a stone mold, engrave the stone mold according to the design pa...

Problems solved by technology

[0003] The first step of the tin inlay process is to make a stone mold, engrave the stone mold according to the design pattern, and open the liquid pouring channel, and the second step is to paste the mold on the flat stone plate or flat iron plate with an angle of 20-30 degrees. Put a layer of filter paper or kraft paper in the middle. The third step is to dissolve the blunt tin to form tin liquid. The heating temperature is 260-300°C. The fourth step is to inject the tin liquid into the stone mold. After solidification, a rough pattern can be taken out Type, the fifth step is to remove the excess part, and then use an iron file to flatten the surface of the pattern, and then use 150#, 220#, 320#, 400# sandpaper to polish the surface of the pattern in turn, and the sixth step is to use various The chisel chisels the pattern to form a qualified product, and then inlays it on the tea set or vase with other patterns. The disadvantage is that each pattern has to go through this cumbersome process, which can be described as labor-intensive, time-consuming and labor-intensive, and the work efficiency is low. The cost increases, the sales unit price is higher,
