Embodiment 1
[0095] Here we take circular chess pieces as an example, such as Figure 4 As shown, the chess pieces 2 include sheet-shaped chess pieces made of non-magnetic materials such as wood materials, and the chess pieces 2 are embedded with soft magnetic spherical particles 4. Specifically, the chess pieces are embedded with soft magnetic materials with a diameter less than half the thickness of the chess pieces. 18 iron ball granules (here, the number can be more or less, as long as the volume does not exceed the limit, it can be at least one grain or only one flake or one piece is not limited, and it is only an example here). Chess pieces have 9 grains on the upper half and 9 grains on the lower half. One of the 9 grains on the upper half is located on the upper half of the geometric center axis perpendicular to the positive end face 5 of the chess piece, and the other 8 grains are evenly distributed on the center of the circle on the geometric center axis, and half the radius of t...
Embodiment 2
[0098] Such as Figure 5 Shown are go chess pieces, and the shogi chess pieces and mahjong boards mentioned later also include Figure 6 Another mahjong brand in , its structure is the same as Figure 5 Go chess piece is identical, and difference is only that appearance is different, and function is also different to some extent; Making thickness is in the scope of 0.5-3mm, also can expand to the method for the go chess piece of 0.1-7.5mm thickness, chess piece, mahjong board, embodiment here Just for a brief description, the specific production size and production method of chess pieces can be adjusted according to the actual production process conditions and method operations. Method process: the magnetic material is soft ferrite powder, and the non-magnetic material is thermoplastic or thermosetting plastic: polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyoxymethylene, polycarbonate, polyamide, acrylic plastic , other polyolefins and their copolymers, po...
Embodiment 3
[0100] The difference from Example 2 is that the magnetic material is uniformly mixed soft magnetic ferrite powder and a small amount of unmagnetized hard magnetic material powder, and the hard magnetic material powder can be hard magnetic ferrite powder , such as AlNiCo alloy, TiCo alloy, BaFe12O19 of barium ferrite, etc. The difference from Example 2 is that before the solidification of the injection-molded mahjong blanks, a process of adding N and S polar magnetization to all the same specification mahjong blanks along the thickness direction of the mahjong is required, so as to obtain the same direction after curing. Mahjong tiles with extremely weak magnetic attraction or magnetic repulsion between tiles when stacked or reversely stacked together.
[0101] And these mahjong tiles are magnetized to the same polarity in the vertical direction on the front end or the opposite end face, so that when the same end faces are stacked together in sequence, mahjong tiles with sligh...
