Description
Technical field
The utility model belongs to LCD backboard punching techniques field, and in particular to a kind of backboard die for punching.
Background technology
The following process of experience is usually required in LCD backboard process：Blanking, punching, trimming, punching, sprout, upper folding
Curved, lower hook, lower bending, trimming, marking, punching, trimming and offset shaping.Wherein, punching is one extremely heavy to backboard processing
The process wanted.
Punching blanking mould is needed to use during backboard punching.Existing mold structure is excessively simple, causes punching and blanking process
Relative position between middle mould and backboard to be processed can not ensure, and then cause the hole site on backboard undesirable, drop
Low yield rate.Existing backboard punch pattern also exist it is less efficient, in face of a large amount of backboards need processing when, its efficiency
It is not enough more obvious.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art that there is provided a kind of backboard die for punching.
A kind of backboard die for punching, including：Drift, spring, upper mould, upper mould fixed plate, lower mould, lower mold fixed plate, institute

Mould is fixed in lower mold fixed plate, and lower mold fixed plate is fixed on die shoe, and lower mold fixed plate is right provided with several with lower mould
Neat material-dropping hole, several material-dropping holes have common center line with corresponding drift.
Preferably, the bottom of the upper bolster is provided with positioning sleeve, and the top of die shoe is provided with locating rod, positioning sleeve and positioning
Bar has common center line.
Preferably, the center on the depression bar top is provided with depression bar, and depression bar passes through upper bolster centre bore.
Compared with prior art, the beneficial effects of the utility model：
The utility model realizes falling automatically for punched scrap by setting material-dropping hole and drift with common center line
Material, while by setting spring, punching complete back punching head can automatic rebounding, with easy to use, efficiency high, speed is fast, production
The measured advantage of quality.
