Cope match-plate pattern is provided with the location hole for locked with bolts, and bolt is locked mutually through screw hole and location hole, by the adjustment of rectangular screw, patrix is aimed at counterdie, fits completely, zero deflection; Guarantee the apparent size quality of shaping rear material.Inner for shaping rear aluminium film redundance cutting knife excision is reserved the condition that can encapsulate and is placed in aluminium film by battery core by staff, by patrix and counterdie pressing, under the state of high temperature, make the pp layer in aluminium film carry out fusion shaping, the open slot of patrix and counterdie makes encapsulation leave a place in pressing to inject electrolyte notch for rear operation.
Cope match-plate pattern and upper bolster are all in rectangular-shaped.
Adopt above structure, be conducive to improving the stationarity between cope match-plate pattern and upper bolster, immovability when avoiding upper bolster to be fixed on cope match-plate pattern, facilitates the adjustment of staff, ensure patrix and counterdie just to property.
The external diameter of covering cutter is 45mm, and internal diameter is 40mm.
The external diameter of interior envelope cutter is 18.5mm, and internal diameter is 13.5mm.
Only when the external diameter of external diameter and interior envelope cutter that the external diameter of covering cutter is greater than battery core is less than the internal diameter of battery core, covering cutter and interior envelope cutter just can play it and act on accordingly, and its outer sealing of the annular lithium battery after pressing is good has apart from battery core the space that certain need inject electrolyte.
The width of described otch is 5mm.
The width of otch is not easily excessive, and the notch that two otch are formed relatively mates mutually with the instrument injecting electrolyte.
Described covering cutter and interior envelope cutter are all fastenedly connected on upper bolster.By heat transfer, reach encapsulation condition.
Adopt above structure, during work, avoid covering cutter and interior envelope cutter to rock on upper bolster, improve covering cutter, concentricity, the depth of parallelism and stability between interior envelope cutter and upper bolster.
Compared with prior art, the advantage of the inside and outside encapsulating mould of this annular lithium battery be this annular lithium battery inside and outside encapsulating mould its achieve lithium battery and present in the mode of abnormity, break the market of quadrate lithium battery in the past, there is good prospect, high financial profit, structure is simple, and cost of manufacture is low.
