Have and stretch out the consistent hole of hexahedral one side shape, cylinder top edge also has two small sircle holes, for installing suspension hook；
In the shaping outer punching include being inverted in empty three layers of estrade, upper two layers are round platforms, below one layer be punch, rush
Head cross section has stretching hexahedral face shape of cross section consistent with flower-drum plate, has roundlet in the side of middle one layer of round platform
Hole, for being vented；
Optimization, there is chamfering at one layer of the centre round platform edge of outer punching in shaping；
In the shaping interior punching include being inverted in empty three layers of estrade, upper two layers are round platforms, below one layer be punch, rush
Head cross-sectional profile has stretching hexahedral one side cross section internal via shape consistent with flower-drum plate, in the side of middle one layer of round platform
There is small sircle hole, for being vented, diameter of bore is consistent with flower-drum plate circular hole face diameter of bore；
The next punching of shaping includes three layers of estrade and is composed, and lower two layers are round platforms, above one layer be punch, punch
Cross-sectional profile size has stretching hexahedral step upper surface appearance and size consistent with flower-drum plate, and diameter of bore and flower-drum plate are justified
The outside diameter of hole face is consistent；
Optimization, there is chamfering at one layer of the centre round platform edge for being molded next punching；
It is described shaping following two punch be composed including three layers of round platform, above one layer be cylindrical shape punch, punch outside diameter and flower
Cylinder outside diameter is consistent above clappers, and punch internal diameter is consistent with cylinder diameter of bore above flower-drum plate, and lower two layers are round platforms,
One layer of round platform is used for spacing above, below one layer of round platform be used to demould；
The forming core rod includes the barred body of three sections of cylinders composition, above one section be lead segment, middle one section is profiled section,
Profiled section diameter is consistent with flower-drum plate diameter of bore, below one section be spacing section, be provided with square key groove.
The utility model is designed according to flower-drum plate shape, suitable for the batch production of flower-drum plate, improves production efficiency.
Brief description of the drawings：
Attached drawing 1 is the explosive decomposition schematic diagram of the utility model；
