DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing different types of golf soles using the same mold.

[0002]

2. Description of the Related Art On a sole of a golf shoe, a central grounding member and an outer peripheral grounding member made of a different material are formed on a grounding surface of a front tread portion and a heel portion. A point-type golf shoe sole in which a point formed of a central ground member is integrally formed, and a spike-type golf shoe in which a nut is inserted into the central ground member and a replaceable spike is screwed and fixed to the nut. There is a bottom.

[0003] The former point type golf soles are:
In several places on the bottom surface of the center grounding member forming recess of the mold for forming the center grounding member, the center grounding member is formed using a lower mold having a point recess formed in the same shape as the point,
The center grounding member is pointed at the sole-forming recess of the sole-forming mold comprising a sole-forming lower mold having a sole-shaped recess having a point-shaped recess and a sole-forming upper mold having a sole contact surface. And the outer peripheral grounding member is formed by injection molding means or heat and pressure molding means.

In the case of the latter spike type golf shoe sole, pins for supporting nuts for inserts are set up at several locations on the bottom surface of the central grounding member forming recess of the mold for molding the central grounding member. Using the inserted lower mold for the insert, after molding the center grounding member into which the nut is inserted, from the sole-forming lower mold having the shoe sole concave portion and the sole-forming upper mold having the sole contact surface. A center grounding member is provided in the sole type concave portion of the shoe sole forming die, and the outer peripheral grounding member is formed by injection molding means or heating / pressing molding means;
It is manufactured by screwing a spike made of an arbitrary material onto an inserted nut after forming the shoe sole.

[0005]

According to each of the above-mentioned methods for manufacturing a golf shoe sole, the lower mold for molding the central ground contact member has a point recess having the same shape as the point. In the latter case, a lower mold for inserts having pins upright for supporting nuts for inserts must be used.

[0006] Also, in the shoe sole forming die, the former uses a sole forming lower mold having a sole-shaped recess having a point-shaped recess, and the latter uses a sole forming recess having no point-shaped recess. The lower mold had to be used.

[0007] For this reason, point-type golf soles and spike-type golf soles cannot be manufactured without preparing various types of expensive molds. There is a problem to be solved in that the production efficiency is low and the cost is high because it is necessary to replace and install.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems. A point type golf shoe sole and a spike type golf shoe sole can be efficiently and inexpensively formed by using the same mold. It is an object of the present invention to provide a method of manufacturing different types of golf soles using the same mold.

5) is closed, resin is injected, and the outer peripheral grounding member (4) is formed by injection molding means or heat and pressure molding means. In the case of the spike type golf shoe sole, it is optional after molding the shoe sole. A spike (7) made of the above material is screwed and fixed to an inserted nut (6), and different types of golf soles are manufactured using the same mold.

[0010]

According to the present invention described above, the lower mold and the upper mold for molding the center grounding member are commonly used, and a point having the same shape as the point is provided at several locations on the bottom surface of the central grounding member forming recess of the lower mold. A point-type golf shoe sole and a spike type are formed by forming a concave portion for the point and fitting a point-shaped supporting member having the same head as a point supporting the nut for the insert into the concave portion for the point. A common lower mold can be used for the golf sole of the present invention, and the sole forming includes a bottom forming lower mold and a bottom forming upper mold.
Using a mold in common, a sole mold recess having a point-shaped recess is formed in the bottom mold, a sole contact surface is formed in the bottom mold, and the sole mold of the sole mold is used. Since the point or the point-shaped support member of any one of the center grounding members can be disposed in the concave portion, the shoe sole molding die also has a point type golf shoe sole and a spike type golf shoe. The bottom can be used in common.
