Automobile sheet metal pressing die

Abstract

The application discloses a kind of automobile sheet metal metal pressing mould, it is related to pressing mould technical field, including upper die holder and lower die holder, the upper die holder is provided with large mould and small mould, the inside fixed connection of the upper die holder has oil pipe one and oil pipe two, the bottom of the upper die holder is fixedly connected with four guide columns, the mutual cooperation between the above structure, when replacing mould, covering area adjusting component automatically switches oil pipe working state, so that the spraying range of lubricating oil is adaptively adjusted according to metal pieces of different sizes, when mould is closed, stepping drive component drives extrusion plate to quantitatively intermittently extrude lubricating oil of oil storage cavity into guide sleeve, periodically self-maintaining guide sleeve, ensuring the mould guiding accuracy under long-term use condition, when extrusion plate resets, early warning component triggers warning block to move, so that conductive block is separated from abutment, and blocking mechanism blocks the top of guide sleeve, further provides guarantee for the guiding accuracy of mould closing.
