Description

  The present invention relates to a method for manufacturing a resin game board used in a gaming machine using a pachinko ball such as a pachinko, an arrangement ball, or a sparrow ball as a game medium.

  As is well known, game boards such as pachinko, arrange balls, sparrow balls, etc. are made of plywood or synthetic resin and formed into a flat plate shape, with nails, windmills, regular prize openings, variable prize openings in the game area on the front. An electronic display or the like is arranged. A game ball launched from the launching device flows down the game area while colliding with a nail, a windmill, etc., and flows into a winning opening or an outlet at the lower end. Enjoy watching the movement. Such a game board is made of synthetic resin instead of plywood from the viewpoint of defective product generation due to deformation of wood, and from the viewpoint of environmental protection and design, and was especially molded by transparent synthetic resin Since the game board can arrange a symbol display device and various decorative members on the back side, it has an advantage that a novel design can be taken and the interest is enhanced.

By the way, generally, game boards need to form mounting holes in various shapes according to the size of the variable prize opening, electronic display, or their arrangement position, shape, etc. Accordingly, it is necessary to manufacture a variety of game boards. For this reason, when trying to mold these various kinds of game boards by injection molding of synthetic resin, there is a problem that a large number of molds are required and the manufacturing cost is remarkably increased.
On the other hand, Patent Document 1 below shows a game board manufacturing method in which a flat synthetic resin plate is formed by an extrusion molding method, and a mounting hole and a nail hole are cut using the router processing machine. Has been.
Moreover, the following patent document 2 has a description of a manufacturing method in which a mounting opening is integrally formed when a game board is molded by an injection molding method.
Furthermore, in Patent Document 3 below, by providing a frame fitting portion in a molding die used in the injection molding method and providing a frame (nesting) so that it can be mounted and replaced, the shape of an opening such as a display window of a display device The game board manufacturing method is shown in which an opening of a winning device or the like, an out-ball discharge port, a nail hole, and the like are formed by subsequent machining.

However, since the manufacturing method shown in Patent Document 1 is to form all openings in a flat synthetic resin plate by cutting, there is a disadvantage that it takes processing time and the production efficiency is not good. Since all resin material in the opening becomes waste as cutting waste, the material yield is poor, especially when manufacturing a game board that requires a large opening for mounting a large electronic display or accessory. Therefore, there is a problem that the cost of disposing it as a waste material increases, and resources are wasted.
Moreover, although the manufacturing method shown in Patent Document 2 does not waste material as in Patent Document 1, a dedicated mold must be prepared for each model of gaming machine, which is as large as a gaming board. A mold that can mold a molded product takes time and cost to manufacture, and has a problem that it cannot cope with a sudden design change or a trend of models in a short time.
In addition, the manufacturing method disclosed in Patent Document 3 has a problem in that it tends to cause molding defects because the cooling effect and temperature distribution of the entire molding die that affect the fluidity of the molten resin vary depending on the shape of the piece. In addition, since a groove-like line is formed on the game board surface of the molded product at the part that hits the boundary between the piece fitting part and the piece of the molding die, it looks bad and the transparency necessary for the game board is also impaired. There is a problem of being.
The present invention is intended to solve such problems.

Therefore, in the invention described in claim 1, in order to attach various types of board components having different shapes and sizes to specific parts of the resin game board, openings corresponding to the board parts are formed in the specific parts in advance. When manufacturing various types of resin game boards, the size of the openings of specific parts of the various types of resin game boards is the smallest, and the outer peripheral edge of the opening is another resin game board one kind of resin game board by one of the injection molding die so that the reference aperture is formed by injection molding only to the common opening region which does not protrude the outer peripheral edge of the opening of the specific part number is molded, after its required shape cutting to the reference opening peripheral edge of the reference opening by router machining, and extended to the required size, characterized in that the board parts in an opening extended is to be attached.
Further, in the invention of the method for manufacturing a resin game board according to claim 2, the specific part is one part that forms the largest opening among a plurality of openings formed in the resin game board. It is characterized by.

  A variety of game boards can be manufactured easily and quickly at low cost, and the production efficiency is improved.
