Description

Molding demolding device of sequential processing material

The present invention relates to a molding demolding apparatus of a sequential processing material, and more particularly, to a molding demolding apparatus of a sequential processing material which allows the sequential processing material to be demolded smoothly from the lower mold part to the upper part after compression molding of the material.

In general, forging is a molding method that gives plastic deformation by pressing a material such as iron or nonferrous metal. In this way, the forging operation for compressing the material is performed by a press machine (hereinafter, referred to as a "press") including upper and lower molds.

In the past, when a plastic material is processed through forging, a single molding method is known in which a single material is compressed to form a forged molded product.In addition, a long plate material is put into a progressive press to sequentially process the material. A sequential molding method for molding a forged molded article is known.

Hereinafter, as an example of the conventional sequential forming method, look at the "sequential transfer processing apparatus" (hereinafter, "the conventional sequential transfer processing apparatus") of the Republic of Korea Patent Registration No. 0417939 as follows.
