Method for producing two-sided bicolor go pieces and gobang pieces through compression molding

Abstract

The invention discloses a method for producing two-sided bicolor go pieces and gobang pieces through compression molding. Urea formaldehyde plastic powder or melamine-formaldehyde plastic powder with added coloring agent and filler with high density is compressed to form go pieces or gobang pieces the same as the go pieces by adopting a compression molding machine and a compression molding mold; black pieces and white pieces are integrated as a whole; the upper and lower surfaces of the pieces have two colors; and one set of the pieces only has two-sided bicolor pieces. The method has the advantages of high production efficiency, simple and cheap mold and cheap and easily-obtained material, and the obtained products have the advantages of high hardness, wear resistance, durability, aging resistance and beautiful color and appearance.

Description

technical field [0001] The invention discloses a method for manufacturing double-faced double-color go pieces and backgammon by compression molding, which belongs to the chess manufacturing method in cultural and sporting goods. Background technique [0002] Go has a high degree of popularity in Greater China, Japan, and South Korea. In recent years, it has begun to spread to foreign countries. Backgammon is available both at home and abroad, and its spread is wider. The Gobang pieces are the same as Gobang pieces. The chess pieces are all single black or white. When playing chess, the two players hold black and white chess pieces respectively, and place pieces on the board in turn. After a game of chess, they have to sort the black and white chess pieces and put them into two boxes, which is a waste of time; 1992 When I was a high school student, I played Go for the first time.

[0002] Go has a high degree of popularity in Greater China, Japan, and South Korea. In recent years, it has begun to spread to foreign countries. Backgammon is available both at home and abroad, and its spread is wider. The Gobang pieces are the same as Gobang pieces. The chess pieces are all single black or white. When playing chess, the two players hold black and white chess pieces respectively, and place pieces on the board in turn. After a game of chess, they have to sort the black and white chess pieces and put them into two boxes, which is a waste of time; 1992 When I was a high school student, I played Go for the first time. At that time, I thought of making the Go pieces into the shape of sugar-coated pills (the top view and the bottom view are all round, and the front view is oblate). The upper and lower sides are white and black respectively. There is only one kind of two-sided two-color chess pieces. When playing chess, the two players can put their own chess pieces on top of the chess pieces. Because the chess pieces are all the same, they don’t need to be sorted after playing chess. They are packed in a chess box; more than 20 years have passed , I haven’t seen this kind of two-sided two-color chess pieces in the market. I searched for patents and found that someone had applied for a patent for black and white two-color Go pieces in 1986, but no one had made this kind of chess pieces. The main reason is that there are 361 chess pieces in a pair. Many white chess pieces are prone to paint falling off when one side is dyed black. The black and white half pieces are bonded or snapped together. It takes too much effort and is easy to fall off and separate. For the production of this kind of chess pieces, the patent of this double-sided and double-color chess piece itself has expired; the invention patent I am applying for now is a high-efficiency and low-cost double-sided double-color Go piece and Gobang chess piece manufacturing method, using this innovative manufacturing method , can push this kind of chess pieces to the society as soon as possible, and inspire innovative thinking for users. The unity of black and white chess pieces conforms to the philosophical law of the unity of opposites, and can also increase the cultural atmosphere of Go itself.
