Description

A kind of mah-jong pieces

Technical field

The utility model relates to a kind of mah-jong pieces, especially relates to a kind of solid mah-jong pieces.

Background technology

The employed mah-jong pieces of people are all made with organic material now, and for saving expensive organic material, mah-jong pieces have employing hollow, and still, this mah-jong pieces do not have the weight sense of solid mahjong, thereby feel are bad owing to hollow and light.So the someone adopts with other material the board body is filled.As the applying date be the China Patent No. ZL:00238072.2 on August 28th, 2000, open day be May 30 calendar year 2001, is called the patent of " solid mah-jong pieces ", it comprises board body and board name, the board name is engraved in the one side of board body, and the board body can be as a whole, also can be made up of surface layer and bottom.Wherein, the one side of solid has locating hole, and the board body wraps solid fully, and is integral with the solid strong bonded, and the pit of mah-jong pieces bottom and the pit of surface layer are engaged, in they are withheld jointly solid is wrapped in by injection moulding.These mah-jong pieces have been saved pmma material, and quality is heavier, comfortable feel during use.

But there is following defective in the solid mah-jong pieces of this structure: 1), the board body of mah-jong pieces is an integral body, the shaping of producing once, mah-jong pieces can only be solid colors, lack the sort of aesthetic feeling of double-colored board body.2), the board body of mah-jong pieces is made up of surface layer and bottom, the structure of withholding of mutual interlock is adopted in its contact position, current mah-jong pieces generally are with harder materials such as lucite, so, mah-jong pieces are difficult to interlock or damage the board body easily when interlocks during fabrication, produce waste product; If use soft material, though solve the above problems, texture is not as the effect of organic material.3), the surface layer of mah-jong pieces and the structure of withholding that bottom is the mutual interlock of gradation injection moulding, contact area is very little between them, and mah-jong pieces are in use, tend to bump, and are easy to generate the crack absciss layer, the phenomenon of scrapping.4), when making this solid mah-jong pieces, need carefully on the solid insertion reference column, this process influence speed of production, and in the process that the injection machine high pressure shoots material, easily break reference column and mold damage, so, increased the difficulty of technology.

Summary of the invention

The purpose of this utility model be to address the aforementioned drawbacks and a kind of rational in infrastructure, hard durable is provided, technology difficulty is little and the mah-jong pieces of good looking appearance.

Technology solution of the present utility model is as follows:

A kind of mah-jong pieces comprise at the bottom of board name, board face, the board and the board core, and the board name is engraved on the board face, is provided with boss at the bottom of the board, has groove on the boss, and the board core places in the groove, and board bread wraps boss periphery at the bottom of the board, and combine securely with at the bottom of the board.

Embodiment 1: described boss is cuboid.

Embodiment 2: described boss is cylinder.

The position of corresponding pit can exchange on boss at the bottom of the described board and the board face.

Described board face is to be injection-moulded in plastic material at the bottom of with board.

Scribble one deck crosslinking agent between at the bottom of described board face and the board.

Described board name and board face are together injection mo(u)ldings.

Outstanding effect of the present utility model is:

1), mah-jong pieces of the present utility model utilize the boss that is provided with at the bottom of the board, increase at the bottom of the board and the contact area of board face, combine securely at the bottom of making board face and board, therefore, mah-jong pieces are sturdy and durable, especially be coated with the last layer crosslinking agent between them, solved the absciss layer problem of gradation injection moulding, its effect is better.2), at the bottom of the board and the board face be injection mo(u)lding respectively, again the board core is placed in the groove of boss at the bottom of the board, be board face corresponding in the injection moulding at last, its technology difficulty is little, helps improving the speed that mah-jong pieces are produced.3), make double-colored mahjong by the plastic material of different colours, its good looking appearance at the bottom of board face and the board.

The specific embodiment

See Fig. 1, Fig. 2 and a kind of mah-jong pieces shown in Figure 3, comprise at the bottom of board name 1, board face 2, the board 3 and board core 4, board name 1 is engraved on the board face 2,3 are provided with boss 5 at the bottom of the board, have groove 6 on the boss 5, board core 4 places in the groove 6, and board face 2 wraps at the bottom of the board 3 boss 5 peripheries, and with 3 combine securely at the bottom of the board.Described boss 5 is cuboid.

As shown in Figure 4, described boss 5 is cylinder.

The position of corresponding pit can exchange on boss 5 at the bottom of the above-mentioned board and the board face 2.

Above-mentioned board face 2 is with 3 being to be injection-moulded in plastic material at the bottom of the board.

Scribble one deck crosslinking agent 7 between 3 at the bottom of above-mentioned board face 2 and the board.

Above-mentioned board name 1 is together injection mo(u)ldings with board face 2.

At the bottom of the board of said structure mah-jong pieces 3 and board face 2 are respectively injection mo(u)ldings, again board core 4 is placed in the groove 6 of 3 boss 5 at the bottom of the board, be board face 2 corresponding in the injection moulding at last, its technology difficulty is little, helps improving the speed that mah-jong pieces are produced.In addition, by being provided with boss 5 on 3 at the bottom of the board, increase at the bottom of the board 3 with the contact area of board face 2, make board face 2 and 3 combine securely at the bottom of the board, therefore, mah-jong pieces are sturdy and durable, especially between them, be coated with last layer crosslinking agent 7, solved the defective of gradation injection moulding absciss layer.Its effect is more durable, more firm.3 make double-colored mahjong, its good looking appearance by the plastic material of different colours at the bottom of above-mentioned board face 2 and the board.

So that mah-jong pieces of the present utility model have is rational in infrastructure, hard durable, technology difficulty The advantage of little and good looking appearance.
