Description

Shaping mould

Technical field

It the utility model is related to mould applications, more particularly to a kind of shaping mould.

Background technology

The stamping process planning of automobile panel is to determine shaping according to product structure shape and technical requirements, repair The sequencing of the processes such as side, punching, flange, shaping and the particular content of each operation, with the extensive application of high-strength plate, it zero Part trimming is essential, and its shaping effect suppresses guarantee mainly by R angles.

Its stamping parts type face of some inner beam reinforcement plates is U-shaped moulding, and because part material is high-strength plate, it sets after shaping Meter trimming carries out shaping, and shaping mould is as shown in Figure 1.In the shaping mould structure, retainer core is with cavity plate cut-off rule in R Angle ensure precision at, as above line journey is less than design runlength, especially on toggle joint press, punch-pin with can not be complete at cavity plate R angles Fitting, shaping effect is poor, and retainer core can not ensure zero clearance with cavity plate segmentation portion, impression be present at R angles after its part forming, Part retainer has push rod, increase mould closure height, increase mold design constraint simultaneously.

Conventional cosmetic mould structure is as shown in figure 1, including part 1 ', shaped insert 2 ', insert set 3 ', retainer core 4 ', pad Plate 5 ', two level push rod 6 ', feet 7 ', supporting plate 8 '.Retainer core ensures at precision that as above line journey is small with cavity plate cut-off rule at R angles In design runlength, especially on toggle joint press, for punch-pin with can not be bonded completely at cavity plate R angles, shaping effect is poor, and retainer core with Cavity plate segmentation portion can not ensure zero clearance, impression after its part forming at R angles be present, while part retainer has push rod, increase Add mould closure height, increase mold design constraint.

The conventional cosmetic mould, its shaping effect are constrained by mold stroke requirement, and precision is difficult to ensure that；And retainer core with Cavity plate segmentation portion can not ensure zero clearance, impression be present at R angles after part forming；Part retainer has push rod, increases mould Closure height, increase mold design constraint.
