Abstract
A kind of high-precision Compound Extrusion piston pin mold, it is provided with backing plate and lower pressure plate, the lower end of backing plate is provided with lower pressure plate, cushion block is provided between lower pressure plate and backing plate, the upper end of backing plate is provided with cavity plate, it is provided with low punch on the inside of the cavity plate, liftout set is provided in low punch, lower die holder is connected with by the lower pressure plate.Mold using when low punch can be allowed without breakage phenomenon, no bending phenomenon is improving Product Precision, reduces production finished product, has in terms of extending punch service life and is obviously improved, the use enhanced convenience of mold can carry out high-precision operation.
Description
Technical field
The utility model is related to a kind of molds, and in particular to a kind of high-precision Compound Extrusion piston pin mold.
Background technology
Piston pin it is more demanding, at present for environmental protection, the higher and higher standard of engine emission makes each part manufacture essence
Degree is significantly promoted.The technique that piston pin mainly produces is blanking, annealing, phospholeum, cold extrusion, heat treatment, grinding, spy
Wound.Cold extrusion is particularly significant in this several procedure, and our company is coordinated up and down plus lower die holder with four-column type hydraulic press
Two punches made with 6542 materials opposite extrusion forming mutually, intermediate there are gross weight holes, be separately to want in extrusion process
Ensure the concentricity of both ends pin endoporus, single-ended concentricity, total length.Since upper and lower caput length is inconsistent, and lead to two
Intensity, toughness causes lower opening concentricity deviation occur less than cause when punch stress.And present engine is to high-performance, big
Horsepower, low emission transition, piston pin extrusion moulding process has been unable to meet working condition requirement at present.
Invention content
The purpose of this utility model is to provide a kind of a kind of indeformable, high-precision high-precision Compound Extrusion piston pin mould
Tool.
The technical solution of the utility model is：A kind of high-precision Compound Extrusion piston pin mold, is provided with backing plate and pushing
Power plate is provided with lower pressure plate in the lower end of backing plate, cushion block is provided between lower pressure plate and backing plate, set in the upper end of backing plate
It is equipped with cavity plate, low punch is provided on the inside of the cavity plate, is provided with liftout set in low punch, by the lower pressure plate
It is connected with lower die holder.
It is provided with guide post on the lower die holder.
The both sides of the cavity plate are provided with cavity plate trim ring, and cavity plate trim ring screw is provided on cavity plate trim ring.
It is provided with punch insert on the downside of the cavity plate, pin joint component is provided between the punch insert and backing plate.
The pin joint component is straight pin.
It is provided with ejection block on the downside of the low punch, the fast downside of liftout is provided with bottom knockout bar.
It is provided with ejector beam on the inside of the cushion block.
The utility model has the advantages that：Mold using when low punch can be allowed without breakage phenomenon, no bending is existing
As improving Product Precision, reducing production finished product, have in terms of extending punch service life and be obviously improved, the use of mold is more
The convenience added can carry out high-precision operation.
