Abstract
The utility model relates to a cold extrusion forming mold of a piston pin oil press, which is used in cold extrusion forming of piston pins and comprises an upper cushioning plate, a lower cushioning plate, an upper mold pressing plate, an upper mold holder, a guide sleeve, a guide post, a lower mold holder, a pressing cover, a matrix, a lower pressing plate, a lower bearing pressing plate, an upper punch bar and a lower punch bar. The upper cushioning plate and the lower cushioning plate are respectively fixed onto the upper mold holder; the upper mold pressing plate is fixed onto the lower cushioning plate; the guide sleeve is fixed onto the upper mold holder; one end of the guide post is fixed onto the guide sleeve while the other end is fixed onto the lower mold holder; the pressing cover and the lower bearing pressing plate are respectively fixed onto the lower mold holder; the matrix and the lower pressing plate are fixed inside the lower mold holder; one end of the upper punch bar is in a round-table shape and fixed onto the upper mold pressing plate, and the other end of the upper punch bar extends into the matrix; and one end of the lower punch bar is in a round-table shape and fixed onto the lower pressing plate, and the other end of the lower punch bar extends into the matrix. Since the fixed ends of the upper punch bar and the lower punch bar adopt the round-table shapes, the cold extrusion forming mold has the advantages of easy adjustment, simple disassembly and convenient maintenance.
Description
Technical field
The utility model relates to a kind of piston pin hydraulic press cold extrusion molding mould, is used for the cold extrusion shaped of piston pin.
Background technology
The piston pin hydraulic press cold extrusion molding mould of prior art comprises rim plate, following rim plate, upper punch rod, patrix cushion block, upper molded plate, upper bolster, guide pin bushing, guide pillar, stop collar, gland, die, the pre-collar of die, die backing plate, cushion cover, liftout cover, following rod, die shoe, following bearing plate, gasket ring, lower platen, ejector beam and the pressure ring of dashing.One end of upper punch rod adopts screw thread to fix or be weldingly fixed on the upper molded plate, and an end that dashes rod down adopts screw thread to fix or be weldingly fixed on the lower platen, and this makes that the dismounting of hydraulic press extrusion die is loaded down with trivial details, consuming time long, causes inconvenient maintenance.
The utility model content
The technical problems to be solved in the utility model overcomes above shortcomings in the existing structure exactly, and a kind of reasonable in design, piston pin hydraulic press cold extrusion molding mould easy to maintenance are provided.
The technical scheme in the invention for solving the above technical problem is: a kind of piston pin hydraulic press cold extrusion molding mould comprises rim plate, following rim plate, upper molded plate, upper bolster, guide pin bushing, guide pillar, die shoe, gland, die, lower platen, following bearing plate; Last rim plate and following rim plate are separately fixed on the upper bolster; Upper molded plate is fixed on down on the rim plate; Guide pin bushing is fixed on the upper bolster; One end of guide pillar is fixed on the guide pin bushing, and the other end is fixed on the die shoe; Gland and following bearing plate are separately fixed on the die shoe; Die and lower platen are fixed in the die shoe; It is characterized in that: also comprise the upper punch rod and dash rod down; Described upper punch rod one end is a truncated cone-shaped, and this end is fixed on the upper molded plate, and the other end of upper punch rod puts in the die; Described is truncated cone-shaped towards an excellent end down, and this end is fixed on the lower platen, and the other end that dashes rod down puts in the die.
Have the cavity of truncated cone-shaped on the upper molded plate described in the utility model, an end of upper punch rod truncated cone-shaped is fixed in this cavity.
Have the cavity of truncated cone-shaped on the lower platen described in the utility model, the end towards excellent truncated cone-shaped is fixed in this cavity down.
The utility model compared with prior art has following advantage and effect: 1, reasonable in design; 2, upper punch rod and the following stiff end that dashes rod all adopt truncated cone-shaped, so easy adjustment, and dismounting is simple, and is easy to maintenance.
