Detailed description of the invention
By explanation the utility model that the following examples can be detailed, open the purpose of this utility model is intended to protect all technological improvements within the scope of the utility model.
Utility model is further described as follows below in conjunction with accompanying drawing: a kind of air-conditioning pad mould, comprises part of the upper die and part of the lower die, and part of the upper die comprises patrix working portion and patrix slave part;
The assembling mode of mould described in the utility model is as described below:
The assembling mode of part of the upper die:
First punch 14 is pressed in punch retainer 10, then ejector block 5 is inserted in punch 14.According to the position, hole on part, load onto die 6, then cover backing plate 12.Guide pin bushing 9 is pressed in upper bolster 8.Screw-in die shank 15 is screwed in upper bolster 8, then stamp spline pin 17.
By push rod 13(tri-) be encased in patrix work component, then push pedal 18 is covered on push rod 13.Assisted by patrix component to cover on patrix work component, with soket head cap screw I 19, both are linked together, after position is adjusted, squeeze into straight pin 11.
The assembling mode of part of the lower die:
By interior hexagonal, die shoe 1 and punch-die 3 are linked together, then squeeze into straight pin I 2.Unloading bolt 22 is encased in die shoe screw bore, loads spring 21, then stripper 4 and unloading bolt 22 are linked together.Then pin stop 20 is arranged on stripper 4.Guide pillar 7 is pressed on die shoe 1.
Under die opening state, the spring 21 of lower mould part is in elastic elongation state, promotes stripper 4 moves, and when plane on stripper 4 keeps concordant with plane on punch-die 3, stripper 4 moves on stopping.Now, spring 21 has certain decrement, to ensure that namely product blank keeps certain pretightning force before stamping-out, makes product stamping-out place's impulse-free robustness and overlap at closed initial period.
Stripper 4 is provided with three pin stop 20, billot is put into the upper surface of stripper 4, with the initial position of pin stop 20 alignment pin determination billot.
When starting working, patrix is descending, first die 6 and stripper 4 acting in conjunction, compresses billot periphery, then the punch cutting edge of punch-die 3 and die 6 acting in conjunction, and meanwhile, the cutting edge of die effect of punch 14 and punch-die 3, carries out blanking, punching stamping-out to billot.
Part of the upper die is continued descending, and to lower dead point position, punching goes out first product.
After stamping-out, part of the upper die is up, and the billot be stuck on punch-die 3 punch cutting edge under the action of the spring 21, ejects by stripper 4.
Part of the upper die is continued up, when beating the crossbeam that bar 16 is encountered on lathe, plays bar stop motion, and part of the upper die is continued up, and static bar of beating promotes push pedal 18, push rod 13 and ejector block 5 by product release, completes the processing of a product.
Promote bar and expect next station, then mould repeats above-mentioned action, completes the shaping of second product.
The non-detailed portion of the utility model is prior art.
