JPS5940407B2 - Method for manufacturing artificial bait fishing hooks - Google Patents

Description

[Detailed Description of the Invention] Traditionally, this type of fishhook was made with a serration part and a fishhook part made separately, and in particular, the fishhook was formed in a V-shape, and the attachment was fixed with a band or the like at the bottom of the serration part. Because of this, mass production has been considered impossible.

The present invention relates to a method for manufacturing an artificial fishing hook that overcomes these drawbacks and enables mass production.

To explain the present invention with reference to the drawings, as shown in FIG.
Artificial bait forming part mold body a, fishhook fixing part mold body and sprue part mold body C
Each of them is constructed into a split mold, and especially the fishhook fixing part mold is
In principle, the number of split molds is determined according to the number of fishhooks, and as shown in the exploded view of the fishhook fixing part mold in FIG. 4, when there are four fishhooks, the mold is composed of four molds.

The number of hooks will be determined as necessary. The four mold bodies are constructed such that the main mold body b' is split into two, and the auxiliary mold body b'' can be freely inserted into the center of the main mold body b' from both the left and right sides.

In addition, the main mold body b' has a fishhook receiving cavity 1 in the center,
A lid body 3 having a fishhook receiver 2 is fixed at a position corresponding to the fishhook receiver cavity so as to cover the fishhook receiver cavity, and a material guide hole 4 is passed through the center of the main mold body b'. I'll keep it.

In addition, the fishhook receivers 2 of the lid body 3 are each provided with a reinforcing material filling groove 5.

An L-shaped fishhook 6 is inserted into the fishhook hole 2 from the tip of the fishhook so that the tip does not hit anywhere on the mold.

The configuration of the auxiliary mold body b// is such that the auxiliary mold main body 7 is formed into a U-shaped cross section, a second lid body 9 having a second fishhook receiving hole 8 is fixed thereto, and a second lid body 9 having a second fishhook receiving hole 8 is fixed to the auxiliary mold main body 7. A fishhook receiving cavity 10 is provided.

The L-shaped fishhook 6 is inserted into the second fishhook receiving hole 8 from the tip of the fishhook, making sure that the tip does not hit anywhere on the mold.

To explain the method of carrying out the present invention using such a mold, first, the fishhook 6 is set in the fishhook fixing molding part molding part, the bait molding part mold a is fixed to one side, the sprue part C is fixed to the other, and the sprue part is fixed. Add the material, let it solidify, and remove each mold to make an L-shaped fishhook fixed to the bottom of the bait, then raise the L-shaped fishhook and form it into a fishhook with the desired angle. do.

The material used in this case is a thermoplastic synthetic resin, a thermosetting synthetic resin, or a metal such as lead.

The method of fixing the bait 11 and the fishhook 6 is to use the reinforcing material filling groove 5 of the fishhook fixing molding part mold body to put extra material into the base of the fishhook 6 so as to cover it. It may be fixed as a thick reinforcement part 12, or it may be fixed with threads 13 as shown in FIG. 8 or 9 of the drawing.

In the present invention, a part of a split mold is used as a bait forming part mold body, the other part is used as a fishhook fixing part mold body, and one part is connected to a sprue part mold body to form a mold body, and the mold body A fishhook is set in the fishhook fixing part mold body, and a material is introduced through the sprue part mold body, the material is solidified, and then the solidified material and the fishhook integrated with the material are separated by the mold body. , Next, since the fishhook is raised at the desired angle, the bait and the hook can be fixed during molding of the bait, making it possible to produce in large quantities and reduce production costs. In addition, the material can be freely selected, and a robust artificial bait fishing hook can be obtained.

Claims (1)

[Claims] 1 The mold body is molded into a split mold consisting of a bait molding part mold, a fishhook fixing part mold, and a sprue part mold, and the fishhook fixing part mold is divided into a main mold with a fishhook receiving cavity and an auxiliary mold. It consists of a split mold body and a lid body that covers the cavity and has a fishhook receiver, and the tip of the L-shaped fishhook is inserted into the fishhook receiver and the tip is inserted into the cavity. At the same time, the base of the fishhook is set along the lid body, and after that, the material is introduced from the sprue mold body, the material is solidified, and the L-shaped fishhook integrated with the solidified material is molded. A method for producing an artificial bait fishhook, which comprises separating the fishhook further and then raising the tip of the L-shaped fishhook to a desired angle.
