DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mass-producing a product in which a metal plate and a synthetic resin material are integrated using a flat metal hoop.

[0002]

2. Description of the Related Art Using a conventional flat metal loop material,
A method of mass-producing a product in which a metal plate material and a synthetic resin material are integrated is a method in which two or more metal plate materials are formed in a flat metal hoop material that is conveyed in the longitudinal direction with its width direction being horizontal. A synthetic resin mold that presses the width direction to the vertical direction and the longitudinal direction to the feed direction, and then moves up and down. Insert molding of these two or more metal plate materials and the synthetic resin material together By cutting and separating the product integrating the metal plate and synthetic resin material from the metal hoop material,
This integrated product was being manufactured.

However, in the above-mentioned conventional method, since the width direction of the metal plate to be cut is oriented in the vertical direction,
It was necessary to make the moving direction of the cutting die for cutting and separating the integrated product horizontal. Further, if the moving direction of the press die for cutting and separating is to be the vertical direction, the width direction of the metal plate is horizontally adjusted in the step of integrally insert-molding two or more metal plates and the synthetic resin material. The direction of movement of the synthetic resin mold must be horizontal. In any case, if the product has two or more metal plates and the width direction of the metal plates is parallel, the direction of movement of the synthetic resin mold should be horizontal or the press mold for cutting and separating. It is necessary to make the moving direction horizontal, and in both cases, there is a problem that the mold structure becomes complicated.

[0004] Further, a flat metal loop material is pressed to form a metal plate material, which is cut and separated from the metal loop material, and then inserted into a mold to form a synthetic resin. In the past, insert molding was also performed integrally with the material, but in this case, the parts were cut and separated from the metal loop material during the manufacturing process of the product, making supply and feeding of the parts complicated. And the positioning cannot be performed with high accuracy.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a very simple mold structure for positioning an integrated product of two or more metal plates and a synthetic resin material from a hoop material. An object of the present invention is to provide a manufacturing method capable of mass production with high accuracy and high speed.

[0006]

According to the present invention, there is provided a method for solving the above-mentioned problems.
And a method of manufacturing a product in which two or more metal plate-like materials and a synthetic resin material described in (1) are integrated. This manufacturing method
Between the step of integrally insert-molding the metal plate and the synthetic resin material, and the step of cutting and separating the integrated product from the metal hoop material, the width direction of the metal plate is oriented horizontally. Is provided with a step of bending 90 ° to the entire surface of the product, so that the entire manufacturing process, that is, a press working device, a synthetic resin molding device, and a bending process and a cutting process are performed over the entire process of the product manufacturing process. The apparatus for separating and processing can be of a type that moves in the vertical direction, and the structure is simplified. Further, since the manufacturing process is performed without cutting and separating the product from the metal hoop material until the final stage, the supply and feeding of the parts are easy, and the positioning can be performed with high accuracy.
