As preferably, described sealing retaining and patrix termination constitute step-like.The patrix termination is that drift is convenient to workpiece machine-shaping, and the sealing retaining constitutes the step-like final molding state that can control the workpiece actinal surface effectively with the patrix termination, guarantees that the product actinal surface is smooth.
As preferably, patrix is a punch, and counterdie is a die, and the bottom of counterdie die cavity is provided with backing plate, and the middle part of counterdie die cavity bottom surface has the through hole that runs through counterdie, is inserted with push rod in the through hole, the lower surface of the upper end contact backing plate of push rod.For ease of Workpiece shaping and depanning, in counterdie, be provided with backing plate and push rod, during the forging moulding, backing plate is the part of entire die, after moulding finished, patrix was up, and push rod also moves upward under the drive of pull bar and promotes backing plate and upwards and with workpiece eject die cavity simultaneously.
As preferably, patrix termination and counterdie die cavity have all designed draw taper, and the draw taper of patrix termination is greater than 0.1 ° ~ 0.3 ° of the draw taper of counterdie die cavity.In order to prevent that workpiece is bonded at patrix and causes difficulty to the demoulding, different draw tapers is arranged in the upper die and lower die design.
As preferably, the gap of backing plate and counterdie die cavity sidewall is 0.1 ~ 0.15mm, and the via clearance of push rod and counterdie die cavity bottom surface is 0.1 ~ 0.15mm.Be provided with like this and be convenient to backing plate and push rod easy on and off motion in counterdie, be convenient to the workpiece depanning.
The beneficial effects of the utility model are: patrix is provided with the sealing retaining around patrix, the bottom surface of described sealing retaining flushes with the counterdie actinal surface, can guarantee that like this workpiece processing back product actinal surface is smooth, product appearance be improved significantly, significantly improved follow-up machined efficient, save raw material, reduced product cost; The diameter d of sealing retaining can prevent the mould explosion less than the diameter D of counterdie actinal surface; Workpiece shaping and depanning are convenient in the setting of backing plate and push rod.
