Claims

[Scope of Claim for Utility Model Registration] An upper mold 5 and a lower mold 6 are arranged horizontally, and a discharge lever operating roller 9 is rotatably mounted on the ram 4.
A discharge lever 11 equipped with a cam 10 corresponding to the roller is pivotally attached to the press body, and a discharge lever actuation spring 13 is tensioned between the press body and the discharge lever, so that the discharge lever is activated when the upper die is raised. The ejection lever is rotated by the force of the spring, and the working end 14 of the ejection lever projects into the mold surface.
When the upper mold is lowered, the ejection lever operating roller rotates the ejection lever in the opposite direction and pushes the working end of the ejection lever out of the mold surface, and there are receiving plate actuation rods 1 on both sides of the ram 4, respectively.
7 is attached, and receiving plate shafts 18 are arranged on both sides of the lower mold, and receiving plates 20 having approximately L-shaped guides 19 are fixed to each receiving plate shaft so as to face each other. Fix the corresponding receiving plate operating lever 21,
Furthermore, a strike plate return spring 22 is provided that always pulls each strike plate inward, so that when the upper die is raised, both strike plates are rotated inward by the force of the strike plate return spring, so that both strike plates are approximately L. A character-shaped guide is located above both edges of the lower mold, and when the upper mold is lowered, each receiving plate actuating rod pushes down each receiving plate operating lever so that each receiving plate opens outside the mold surface. An automatic discharge device for processed products in a press.
