Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings.

As depicted in figs. 1 and 2, convex by barostat 4 and cylinder of the utility model Mould 1 and die 2 etc. form, and are provided with alignment pin 11 and hole 12, location on described punch 1, On described die 2, the position in corresponding first alignment pin 11 and the first hole 12, location sets respectively There is the second hole, location 21 and the second alignment pin 22；The most equal at the middle part of described die 2 Even it is provided with four struts flushed 23.

As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, it is fixed to be installed with in the periphery of described die 2 Position ring 3, is provided with groove in described locating ring 3, rotates and be provided with rotation in described groove Dish 34, described locating ring 3 is along the circumferential direction uniformly provided with six chutes 31, each described The bottom of chute 31 is equipped with one section of groove, each described groove all recessed with in locating ring 3 Groove connects through；It is uniformly provided with six guide fingers 35 in the upper surface of described rotation dish 34, Each described guide finger 35 is upwards fed through the groove of correspondence position, at described limited block 32 Bottom be provided with one section of skewed slot, the traversing through end on described guide finger 35 top is spacing at correspondence position It is slidably connected in skewed slot on block 32；Gear all it is installed with in the upper end of each described chute 31 Plate 33, described limited block 32 is arrow shaped ramp structure towards the top of die 2 one end, The upper surface of described arrow shaped ramp structure flushes with the upper surface of baffle plate 33.
