Description
Technical field
The utility model relates to field of mechanical die, specially a kind of machine die ejecting structure.
Background technique
Currently, the ejecting mechanism of the stamping die used on punching machine is generally the spring handle base by being mounted below mandril
Material ejection.Due to the effect of diaphragm flexures under mandril, mandril is made to remain ejection state in a free state.Upper mold is transported downwards
It is dynamic, two lower mould sliders are subjected to molding and form lower die, and are also pressed downward mandril while completing blank forming, to upper
Mould is depressed into backhaul behind designated position, as upper mold is applied to the elimination of the upper power of mandril, under the action of the spring mandril to
Upper movement ejects blank, completes a blank forming.The shortcomings that prior art is to keep pushing up in a free state due to mandril
It does well, when upper mold moves downward, keeps two lower mould sliders of mandril influence of ejection state to carry out molding and form lower die, in turn
Influence component shaping quality.In addition, the spring below mandril is compressed when workpiece is formed, when upper mold backhaul under mandril
The spring in face extends, and spring is in compression and elongation transition state for a long time, influences spring force, so that mandril work is influenced,
Reduce the stability of ejecting mechanism.
For this purpose, those skilled in the technology concerned improve this, such as Chinese Patent Application No. is
