DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a shoe sole for golf, and the golf ball is manufactured without performing insert molding.
Attach the resin plate to the hook, inject the resin, and put the core on the shoe sole
It is an object of the present invention to provide a method of manufacturing a shoe sole for golf in which water is prevented from penetrating from the ground contact surface to the inner surface of the shoe sole by fixing and fixing the hook .

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional golf shoe sole is manufactured by a golf stud 3 having a pin 2 projecting from a buried seat plate 1. As shown in FIG.
The pin 2 is fitted into a rivet setting recess 6 engraved in the bottom surface 5 of the molding space of the lower sole forming die 4 and a plurality of fixing members that penetrate through the upper sole forming die (not shown). After the tip surface of the rod 8 is in contact with the buried seat plate 1 of the golf tack 3,
This is performed by a method in which a shoe sole molding resin material is injected into a molding space. In addition, the real sho 59-8569
Improves waterproofness from the viewpoint of prevention of peeling in the layer of the tack.
The golf tack was integrated by insert molding
Thereafter, the method is performed by a method of further forming the coating layer.

[0003]

As shown in FIG. 4, a golf shoe sole manufactured by the conventional method shown in FIG . 3 has a plurality of fixing rods 8 which penetrate through a shoe sole forming upper die. After the tip surface of the golf stud 3 is in contact with the buried seat plate 1 of the golf tack 3,
Since the shoe sole molding resin material has been injected into the molding space, a part of the buried seat plate 1 of the golf tack 3 is exposed at the bottom of the hole 11 where the fixing rod 8 of the shoe sole 10 is pulled out. The buried outline of the golf tack 3 is moved from the sole contact surface 12 to the hole 11.
Are formed in communication with each other up to the bottom. For this reason, when the sole molding material is deformed due to bending of the sole, a gap is formed in the buried outline, and the sole contact surface 12 and the sole inner surface 13 are formed.
Is in a communicating state, and there is a drawback that water permeates from the portion. In addition, Japanese Utility Model Publication No.
The core material is inserted first to prevent
After forming, to further form a coating layer, increase the number of processing steps,
Increase in the number of molds due to the increase in the type of soles (size of soles)
In addition, there is a disadvantage that the cost increases significantly.

[0004]

SUMMARY OF THE INVENTION A method of manufacturing a golf shoe sole according to the present invention is characterized in that a pin of a golf tack having a pin protruding from a buried seat plate is provided on a bottom surface of a molding space of a lower mold for molding a shoe. A resin plate that fits into the recess and is fused to the sole forming material is laid on the seat plate embedded with the golf tack, and the tips of a plurality of fixing rods that penetrate the resin plate through the upper mold for forming the sole. After the surfaces are brought into contact with each other, the shoe sole molding resin material is injected into the molding space.

[0005]

As described above, the resin plate to be fused to the shoe sole molding material is superimposed on the golf seat buried seat plate, and the tip surfaces of the plurality of fixing rods are brought into contact with the resin plate. When the shoe sole molding resin material is injected into the molding space, the resin plate is fused and integrated with the molding resin material, the entire circumference of the seat plate is surrounded by the resin, and the fixing seat is pulled out. Some will not be exposed. For this reason, when the sole forming material is deformed due to bending of the sole, etc., even if a gap is formed in the buried outline, it is blocked by the resin plate part, so that the sole contact surface and the sole The communication with the inner surface is prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the method for manufacturing a golf shoe according to the present invention will be described with reference to FIG. 1. Pins 2 made of hardened steel or ceramic, whose base is held by a buried seat plate 1, protrude. The pin 2 of the golf stud 3 is fitted into the stud setting recess 6 formed in the bottom surface 5 of the molding space 5 of the shoe sole lower die 4, and the resin plate 7 made of urethane resin is mounted on the buried seat plate 1 of the golf stud 3. Are placed on the resin plate 7 so that the tip surfaces of a plurality of fixing rods 8 that penetrate and protrude into and out of the shoe sole forming upper mold (not shown) are brought into contact with each other. It is manufactured by injecting.

The golf shoe sole manufactured by the above method is
As shown in FIG. 2, a resin plate 7 made of urethane resin is fused and integrated with a urethane resin material 9 to surround the entire circumference of the buried seat plate 1. The buried seat plate 1 is not exposed at the bottom. For this reason, the sole 10
Even if a gap is formed in the buried outline by deformation or the like due to bending or the like, it is blocked by the resin plate portion, thereby preventing the shoe sole grounding surface 12 and the shoe sole inner surface 13 from communicating with each other. Is done.

[0008]

According to the first aspect of the present invention, a resin plate to be fused to a shoe sole molding material is superimposed on a seat plate for burying a golf tack, and the tip surfaces of a plurality of fixing rods are brought into contact with the resin plate. After injecting the shoe sole molding resin material into the molding space, the resin plate is fused and integrated with the molding resin material, the entire circumference of the seat plate is surrounded by resin, and the hole after the fixing rod is pulled out Since a part of the seat plate is not exposed at the bottom, even when a gap is formed in the buried outline, in the case where the sole molding material is deformed due to bending of the sole or the like, it is blocked by the resin plate portion. As a result, the sole contact surface and the sole inner surface do not communicate with each other, so that water penetration can be prevented. A shoe sole molding material according to claim 2 of the present invention.
And because the resin plate is a similar urethane resin,
The sole molding material and the resin plate are fused and integrated, and the sole is grounded.
The surface and the inner surface of the sole do not communicate with each other, preventing water penetration
be able to. In addition, the spa according to
The sole of the shoe is covered with a thermoplastic synthetic resin core material and a foam resin.
Constructed with a cover layer and insert-molded mounting brackets in the core material
This prevents the mounting bracket from directly contacting the coating layer.
With improved waterproofness and durability.
It is necessary to have a mold for inserting
Insert molds are also required depending on the size of the shoe.
However, the present invention requires only a sole forming mold,
Cost reduction.
