Due to the action of the limit screw, the buffer plate will not separate from the fixed die seat. Under the action of the guide block, the bending forming block moves upward and also moves backward, separating from the right-angle bending area of ​​the injection-molded plastic panel. The formed plastic panel is completely brought out by the passive mold, effectively protecting the plastic buckle formed in the bending area of ​​the plastic panel;

[0032] (2) By setting ejector pins and inclined ejectors, the product can be ejected from the movable mold quickly and effectively while ensuring the integrity of the product;

[0033] (3) Simple structure and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
