Described lower template includes upper plate and lower plate, and the two is bolted, and spacer, described red seat are cased with bolt
It is fixedly mounted between the upper and lower plates.
Spring B is provided between the lower surface of the epimere of described material discharging rod and drift.
The beneficial effects of the utility model are：1st, the utility model is provided with the source of two de- material power, and one is spring
A pretightning force passes to the de- material power formed after the de- material conical surface, when another is upper mould return, the upper end of material discharging rod and punch press
Frame hit after glide so that de- material head push down on box hat formation de- material power.Apply de- material from the both sides up and down of box hat
Power, box hat is not allowed yielding, and de- material percent defective is remarkably reduced.
2nd, the utility model is combined into lower template using upper plate and lower plate, compared with the lower template of integral type, under guarantee
While the depth of template, the weight of mould is lighter.
3rd, the setting of spring B, can keep geo-stationary between material discharging rod and drift, so as to reduce when upper mould is descending
During mold work, the unnecessary abrasion of material discharging rod, while reducing noise.

Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodiment
Scheme some parts to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
Some known features and its explanation may be omitted and will be understood by accompanying drawing.
With reference to each figure, a kind of Thin-wall battery case stretch die lamps structure, including upper mounting plate 8, cope plate 7, lower template
With lower installation board 1, cope plate 7 is fixedly mounted on upper mounting plate 8, and drift 12 is fixedly mounted on cope plate 7, and lower template is fixed
On lower installation board 1, red seat 16 is fixedly mounted in lower template, and the downside of described cope plate 7 is provided with stripper plate 6,
Spring A11 is provided between stripper plate 6 and cope plate 7, the downside of stripper plate 6 is provided with to be matched with the horn mouth at the top of box hat 13
The de- material conical surface 15, the de- material conical surface 15 is inserted in horn mouth, and stripper plate 6 applies downwards in the presence of spring A11 to box hat 13
Pressure, so as to provide a part de- material power, the middle part of described drift 12, which is provided with through hole, through hole, is provided with material discharging rod 9, takes off
Expect that the epimere of bar 9 is thicker, the epimere of material discharging rod 9 passes through upper mounting plate 8 and protrudes from the upper surface of upper mounting plate 8, the hypomere of material discharging rod 9
