Embodiment
The application is described in further detail below by specific embodiment and with reference to accompanying drawing." preceding " in text,
" rear ", "left", "right", " on ", " under " using the laying state of the mould in accompanying drawing as reference.
Existing mold is when the aluminium metal plate 5 to progressive thickness carries out bending and molding, due to being between upper mould 1 and lower mould 2
Vertical relative motion, the two is distributed in vertical direction for what the active force of aluminium metal plate 5 was more concentrated, thus in wrap direction
Enough power can not be provided bending and molding is carried out to aluminium metal plate 5, therefore existing mould is bent into aluminium metal plate 5
During type, there is larger resilience and can not overcome, cause the aluminium metal plate 5 after bending can not meet the requirement of bending angle, be
Overcome resilience and be adjusted in place bending angle, existing moulding process can carry out after bending and molding to aluminium metal plate 5
Bent reshaping, but because aluminium metal plate 5 is softer, and be the local shaping for bending part, therefore, shaping process is easily
The corresponding bending transition face in bending angle is caused press back, impression and galled spots, and then the outward appearance of influence aluminium metal plate 5 occur,
Cause the lifting of bad order rate, so as to increase production cost.
In order to solve the problem of existing mold is easily caused aluminium 5 surface damage of metal plate, as Figure 1-3, the application is implemented
Example provides a kind of mould, including upper mould 1 and lower mould 2,
