The utility model discloses a kind of
trepanning devices for automobile switch plastic production, it is related to the field of automobile switch, including base, four holes are connected in base interior, the air outlet of manual
air pump is connected with gas distribution
pipe one, both ends of gas distribution
pipe one are connected with gas distribution
pipe two, gas distribution pipe two port is through connection with hole, the top end of electric push rod is connected with push block, the side of push block is fixed with limit block.The
trepanning device for automobile switch plastic production, gas distribution pipe one can be shunted again by gas distribution pipe two and discharged, the gas discharged can blow the
processing position of plastic part, accelerate the heat dissipation efficiency after plastic part
punching, and the blow during
punching process can reduce the adhesion of plastic debris, improve the
punching precision indirectly, when top piece moves up to the bottom of plastic part,
extrusion can be carried out, plastic part can be separated after being extruded with base, prevent plastic part from sticking on the surface of base and affect discharging efficiency.
