Abstract

The invention relates to a stamping mould, in particular to a reverse stamping type unloading forming tool. The unloading forming tool comprises an unloading plate arranged on an upper mould and serving as the first unloading plate, an unloading plate arranged on a lower mould and serving as the second unloading plate, an ejection rod, a rotary semicircle and a punch, wherein the ejection rod, the rotary semicircle and the punch are sequentially connected, the upper end of the ejection rod is fixed to the upper mould, the other end of the ejection rod penetrates to the lower portion of the lower mould, the rotary semicircle is installed on a lower mould frame, one end of the upper surface of the rotary semicircle abuts against the lower end of the ejection rod, the other end of the upper surface of the rotary semicircle abuts against the lower end of the punch, the punch penetrates through the lower mould, the first unloading plate and the second unloading plate, the upper end of the punch corresponds to a groove hole in the upper mould in shape and position, and the rotary semicircle is hinged to the lower mould frame and semispherical. The unloading forming tool overcomes the defects that adjustment and positioning of a lever in the prior art are not accurate, and is accurate in positioning when fast operating.

Description

technical field [0001] The invention relates to a die for stamping processing, in particular to a backflushing type unloading forming tool. Background technique [0002] Existing stamping forming process mostly adopts the mode of cooperation of die and punch to carry out punching process, such as Chinese patent CN202411221 discloses a kind of lever mechanism for forwarding die bending and shaping process, on the base of upper die there is a vertical The upper end of the vertical dowel bar has a wedge-shaped adjustment slider, and the outside of the wedge-shaped adjustment slider has adjustment bolts. The vertical dowel bar passes through the stripper plate; the axis of the vertical dowel bar and the lower die The axis of the force bearing column on the base is on the same vertical line, the lower end of the movable force bearing column installed on the base of the lower mold is in contact with one end of the lever installed in the base of the lower mold, and the upper end of...
