Game cards and making method thereof

Abstract

A piece for chess or mahjong is composed of the thick layer which is a rectangular shell with an open internal cavity, the core put in said internal cavity of said shell, and the thin layer which is injected in the gap between said shell and core. It is made of polymethyl methyl acrylate (PMMA). Its advantages are simple structure, high hard, beautiful appearance and low cost.

Description

technical field [0001] The invention relates to an entertainment product and a manufacturing method thereof, in particular to a chess and card and a manufacturing method thereof. technical background [0002] There are various styles of entertainment products used by people now, among which the entertainment of chess and cards is especially favored by people. Such as mahjong tiles, mahjong tiles on the market are all made of organic materials, and wherein, solid mahjong is still used by most people, for saving organic materials, also have to adopt to fill the board body with other substances. For example, Chinese patent ZL: No. 00117369.3 discloses a solid mahjong tile and its production method. It consists of a tile body, a tile name and a solid body in the tile body. The card body completely wraps the solid body and is firmly integrated with the solid body. The tile body of the solid mahjong tile is a whole, which is formed at one time. At this time, the position of the ...

AI Technical Summary

Problems solved by technology

However, plexiglass is not only costly, but also a polymer with high strength and deformation resistance, so it often brings trouble to its processing

And the board body of this mahjong tile is a whole, once made and shaped, the mahjong tile can only be a single color, lacking the kind of aesthetic feeling of a two-color tile body

What's more, when the board body of mahjong tiles is composed of the surface layer and the bottom layer, its contact point adopts a buckle structure that interlocks with each other. If it is made of a relatively hard material such as plexiglass, it is difficult to snap or damage the tile body when snapping, resulting in Waste products; if soft materials are used, although the above problems can be solved, the texture is not as good as that of organic materials, and mahjong tiles often collide during use and are prone to cracking and other problems

What's more, when manufacturing the solid mahjong tiles, it is necessary to carefully insert the solid body into the positioning post. This process affects the production speed, and in the process of high-pressure injection of the injection molding machine, it is easy to break the positioning post and damage the mold. Increased the difficulty of the process
