Abstract
The invention discloses an aluminum alloy oil pump shell trimming die. The trimming die comprises a movable die base, a fixed die base, a fixed plate, a first floating plate, a second floating plate,a floating frame, a punch mounting plate and a plurality of trimming punches, a first spring connected with the first floating plate is arranged at the bottom of the fixed plate; the trimming punchesare respectively fixed below the punch mounting plate; a waist-shaped hole is formed in the top of each trimming punch, a shell pressing block is arranged below the second floating plate, a shell supporting block is arranged on the fixed die base, through grooves corresponding to the bottoms of the trimming punches are formed in the shell supporting block, and floating block extending into the through grooves are arranged in the floating frame. By means of the mode, according to the invention, when the movable die base is pressed downwards, the shell pressing block makes contact with the upperportion of the aluminum alloy oil pump shell to be pressed and fixed, the trimming punches cooperate with the through grooves to cut off burrs, and the cut burrs fall into the through grooves.
