Abstract
A press die includes a lower die with a main molding surface having first and second molding surfaces that define two symmetrical product areas. A blank holder is arranged along an outer edge of the main molding surface and configured to hold a pair of blanks at a proper processing position. Additionally, a rising core is located at a center of the main molding surface between the two product areas. The rising core protrudes upward and is configured to assist in the molding process. The press die enables simultaneous production of symmetrical products as well as a one-sided mold processing.
Claims13
A press die configured to perform a symmetrical molding process and a one-sided molding process, the press die comprising:
- a lower die having an upper surface that defines a main molding surface, the main molding surface being configured to form a pair of products that are symmetric in a left-and- right direction, the main molding surface comprising (i) a first molding surface being configured to form one of the pair of products, and (ii) a second molding surface being configured to form the other of the pair of products;
- a blank holder arranged along an outer circumference of the main molding surface of the lower die, the blank holder being configured to position a pair of blanks to a processing position at the lower die;
- and
- a rising core that is disposed at a central portion of the main molding surface between the first and second molding surfaces and protrudes upward from the main molding surface.
