Description
Technical field
The utility model relates to a kind of forging mold, particularly relates to a kind of forging mold of powder.
Background technology
Forging is a kind of low-cost high-density powdered metal parts near-net-shape technology.Engine link carries and the rectilinear motion of piston is converted to gyration by crank, and not only require tension, bending resistance but also require wear-resisting, antifatigue and shock-resistant, its comprehensive mechanical performance requires very harsh.Have based on PM technique the advantages such as material-saving, energy-conservation, efficient and optimizing tissue structure and powder forging process can make the uniform in material of sintered article, anisotropy and fine and close after its performance meet or exceed steel alloy, propose and adopt powder forging process to produce engine link.Power forging is due to its particularity, high to the performance requirement of mould, and burn failure rate is high.
Utility model content
The utility model is to solve above-mentioned deficiency, provides a kind of cost of manufacture low, the connecting rod powder forging mold of fast changeable.
In order to solve the problem, the utility model provides connecting rod powder forging mold, comprise upper die and lower die, patrix comprises cope match-plate pattern, guide pin bushing, punch, counterdie comprises lower bolster, die socket, die, backing-out punch, push rod, it is characterized in that: described punch is fixed on cope match-plate pattern by punch pressure ring, punch pressure ring is screwed, and its convex mould is provided with the upper impression of mould, described lower bolster is provided with die socket, core rod is provided with in die socket, core rod retainer plate, backing-out punch, lower gasket, die, described core rod is fixed in die socket by core rod retainer plate, core rod is through backing-out punch, the top of backing-out punch is provided with die, die is fixed in die socket by die pressure ring, push rod contacts with backing-out punch with core rod retainer plate through lower bolster, after pressing mold terminates, backing-out punch can be promoted and eject workpiece, described core rod, backing-out punch, lower gasket, die together constitutes the lower impressions of mould, when wherein any portion is damaged, can change at any time, reduce the cost of production mould, and die pressure ring plays the effect of destressing simultaneously, prevent die socket from bearing more stress and the life-span shorter.
Preferably, described punch skin is nitriding layer.
Preferably, described die skin is nitriding layer.
Preferably, described backing-out punch skin is nitriding layer.
The utility model advantage is compared with prior art: broken traditional Design of Dies mode, provide a kind of connecting rod powder forging mold being convenient for changing mould, its structure is simple, mold cavity is made up of multiple part, after each part breaks down, can change at any time for the part damaged, saved production cost, improve the service life of mold integral.
