The middle both sides of fixed plate 3 are respectively equipped with mould 8 in an enlarging, the upper mould and are additionally provided with loading and unloading material machine
Structure；
The lower mould includes bottom plate 14, lower bolster 15 and the lower template 17 being fastenedly connected successively from top to bottom；It is described
The bosom both sides of bottom plate 14 are respectively equipped with mould 10 under an enlarging, the lower mould and are additionally provided with lower shedding mechanism；
Stopping means is provided between the upper mould and lower mould；
Enlarging station in the enlarging of described the same side under mould 8 and enlarging between mould 10 for a product.
The die head of mould 10 is respectively classified into three sections under mould 8 and enlarging in the enlarging, is enlarging leading portion, expansion respectively from top to bottom
Mouth stage casing and enlarging back segment, enlarging leading portion form enlarging positioning ladder with enlarging stage casing, and enlarging leading portion is smaller than enlarging stage casing diameter
0.2mm, enlarging back segment is reduced to each enlarging than the enlarging stage casing small 0.5mm of diameter, and by effective enlarging length of mould in enlarging 8
The enlarging length of section is 9mm.Thus equivalent to enlarging has been carried out to product, secondary (i.e. enlarging leading portion first carries out pre- to product
Enlarging, then enlarging stage casing is again to the whole enlarging of product progress), so as to reduce mould stripping force, product is not bound in enlarging
On mould 8.
The loading and unloading material mechanism includes loading and unloading material plate 7, discharging spring 6 and limited block 5, and the loading and unloading material plate 7 is arranged on
The lower section of fixed plate 3, provided with six limited blocks 5 between loading and unloading material plate 7 and upper mounted plate 3, the centre of upper padding plate 2 and surrounding are uniformly set
