A dry method production process of multi-mode double-sided convex Go pieces

Abstract

A multi-die dual-convex chess piece drying production technology includes pelleting, die forming, burning, shaping and grinding, and detection. The multi-die dual-convex chess piece drying productiontechnology can achieve mechanical production of dual-convex chess pieces; the size, the shape and the concentricity of each chess piece can be controlled well through compression of dies; and the acquired chess pieces are consistent in size and shape. The die has a multi-die structure, and can produce a plurality of chess pieces at the same time.

Description

technical field [0001] The invention relates to the technical field of production and preparation of go pieces, in particular to a multi-mode double-sided convex go piece dry production process. Background technique [0002] It is known that there are basically two shapes of chess pieces, called single-sided convex and double-sided convex. With the development and popularization of Go, Go pieces are not only a kind of cultural activity supplies, but more are used and collected by players as handicrafts. Single-sided convex is commonly used in mainland China, and it is also the most commonly used under the "Chinese Rules". This kind of chess piece is flat on one side and convex on the other, and falls on the board. There are disadvantages such as picking and picking, the sound of playing is loud and fragile, and the formation of noise, and because the chess is flat and thin, it is easy to fall and break when used. [0003] Double-sided convex is an ancient chess shape that ...

Problems solved by technology

[0004] At present, the production and molding process of double-sided convex go pieces is generally divided into two types. One is the cold processing method of mechanical cutting of natural materials. This method is mostly combined with manual and mechanical processing. Only one piece can be processed at a time. The labor cost and The cost of equipment is relatively high, and it is not easy to produce on a large scale

Another method is the convex-concave extrusion molding method, but because the upper and lower sides of the chess pieces are convex surfaces, the process requirements for the forming and demoulding of the chess pieces are very high, and no effective regular forming and molding methods have been found in the prior art. Release process

[0005] The national invention patent with the application number of 200410060485 and the title of the invention is "Fine Porcelain Go and Its Dry Production Process". Firing and other technical processes, but no explanation is given for the production process of double-sided convex chess pieces and multi-mode production

[0006] The national invention patent with the application number of 87102491.8, the invention name is "Double-sided Convex Go Pieces Forming Technology", the patent discloses a double-sided convex structure Go Pieces molding process, which is based on the surface radian of the upper arc of the Go Pieces, using graphite To make a concave mold with the same radian, the liquid molten material is dropped into the concave curved surface mold to form a raised chess piece below, and the upper convex surface is the surface formed naturally when the liquid molten material is cooled. The shape mold is made according to the naturally formed upper convex surface, but when the molten material of each chess piece has no abrasive tools on the upper surface, the cooling environment for each production of chess pieces will be different, relying on the surface formed by natural cooling It is extremely uncertain, and in the actual use of double-sided convex Go pieces, there are very high requirements for the consistency of the two convex surfaces. It must be the same radian and high concentricity, otherwise it will seriously affect the use state

[0007] The molding process disclosed in this invention, first, due to the difference in kiln temperature and ingredients, the quality of the finished product will be different, because the liquid melt relies on manual tools to contact the glass water, drops in the mold, and the liquid melt naturally drops, with different sizes ;In addition, due to the high temperature of glass water, the temperature of glass water cannot be stabilized, which will cause the viscosity of glass water liquid to be different. Under the influence of kiln temperature and room temperature, the finished product is in the mold, and the cooling time is different. The explosion happened

Therefore, this method has low efficiency, high energy consumption, is not easy to form, the size of the finished product is different in thickness, and the yield is extremely low.
