The forging die has the advantages of being convenient to operate and replace, meeting the forging precision requirement of a high-precision product, greatly prolonging service life of the die, reducing energy consumption of equipment and the like.

Description

A kind of valve forging mold

Technical field

The utility model relates to a kind of automobile valve inside and makes the field, refers in particular to a kind of valve forging mold.

Background technology

In the prior art, the former die holder of valve forging mold, die sleeve reach up and down, and the mould guiding principle is that Upper Die-sleeve imports lower die-sleeve, the drawback of this structure: Upper Die-sleeve and lower die-sleeve guiding have increased the error link, the contact of upper and lower mould high frequency time, the phase mutual friction, impact, fatiguability lost efficacy, namely delay work and easily produce waste product.

Summary of the invention

Goal of the invention: provide 1. finish forge valves to forge precision, reduced the machined production link; 2. guide frame is safe and reliable, has improved the axiality requirement of valve retainer end face pit, has reduced percent defective; 3. the structure innovation of alloy model cavity makes the device that improves in service life of mould more than ten times.

Technical scheme: a kind of valve forging mold of the present utility model, formed by upper module and lower module, described upper module is made up of upper molded plate, upper bolster, die shank, upper bolster backing plate, upper bolster trim ring, upper molded plate, upper bolster, upper bolster backing plate are fixedly linked successively, the upper bolster trim ring is between upper bolster, upper bolster backing plate, and die shank is arranged at upper molded plate and upper bolster central authorities;

Described lower module is by the die shoe backing plate, bolt, die shoe, press down template, the valve counterdie, the counterdie pad, the die shoe trim ring, ejector beam, the liftout spring, the liftout support set is formed, the die shoe backing plate, die shoe, pressing down template is fixedly connected sequentially, be provided with the die shoe trim ring between die shoe and the die shoe backing plate, the die shoe backing plate is connected by bolt with die shoe, the valve counterdie is positioned at the central authorities of die shoe, the centre is provided with the groove that is complementary with the valve shape, valve counterdie below is provided with the counterdie pad, counterdie pad below is provided with ejector beam, ejector beam and liftout spring, the liftout support set is connected.

Novel alloy die device design innovation has satisfied the propelling of alloy mold and has used, and guide frame is that patrix directly imports, and guide frame is extremely simple, the cost less investment, patrix only needs normal reparation can guarantee guiding accuracy, and install and operation very convenient.

The utility model advantage: 1. operation and replacing are convenient, satisfy the high accuracy product and forge precision; 2. special die sleeve structure configuration makes the impulsive force that forges directly not impact mould, carries greatly and has done die life; 3. reduce the energy resource consumption of equipment, improved the service life of equipment.
