Water pipe link is a mould production uses grade stock engineering ，adopt pairs of side edge make distance, suppress, unload material, natural blanking large Engine .
This mould unique feature:
(1) the mould retainer plate has a high precision：A long macrobiotic life: the lower mould retainer plate like as protruding model's retainer plate。It's better to select quench sex kind quenching and out of shape light Mould steel products material of alloy to use。Heat treatment reaches to HRC50-55, cut and processed the line, so as to ensure the high precision of the mould retainer plate and macrobiotic life.
(2) Change the concave model of blanking and inlay one quickly: while changing the concave mould, fall with one pin from die mould waste material of backing board hole inlay carry out, produce from the retainer plate concave mould, needn't dismantle screw and pin。Sometimes there is no need to unload the mould from high-speed puncher sometimes, so it is fast to change the concave mould, and can guarantee the repeated assembly precision of the mould, improve the use of the service life of the mould.
