Description
Technical field
The utility model is related to a kind of balancer simultaneously compressing for multimode cavity on a hydraulic press.
Background technology
In composite material moulded shaping, the press power acted on material determines the density of product.In a master cylinder
When suppressing multiple die cavitys simultaneously, the charge error of each die cavity can influence the density of product.But want precise control charge
Be it is difficult, so people often with single cylinder correspondence one-mode cavity, or on master cylinder increase balancer method make each die cavity
Stress is equal.This method is referred to as level specific pressure compacting.
Prior art such as (ZL 200920094282.0) each pressing station has 4 diameter identical master cylinders, each master cylinder
Interior fluid pressure is identical and only corresponds to a die cavity, realizes that level specific pressure is suppressed.Increase fluid communication device formula on a master cylinder
Balancer realizes that the method for level specific pressure compacting is more common.
Above two mode is all the principle of fluid communication device dynamic balance.On the premise of sealing ring frictional resistance is ignored,
Each (post) living plug power output is equal.But in fact the hermetic resistance of each (post) living beyond the Great Wall has very big difference.This
Species diversity has often had a strong impact on the uniformity of product density.In hot forming, fluid communication device formula balancer is also existed
Resistance to heat problem.Too high temperature can make seal failure cause oil leak, restricted lifetime.
Fluid communication device formula balancer requires that machining accuracy is high, thus manufacturing cost is also higher.In addition the pressure-resistant limit of sealing ring
System, balancer piston can not be too small, causes die size to be had to larger, and then also increases the cost of mould.
The content of the invention
The purpose of this utility model is exactly to overcome the shortcoming of existing fluid communication device formula balancer, propose a kind of pure machine
The seesaw type balancer of tool formula structure, to realize level specific pressure pressing process.
The utility model four-point seesaw type balancer, including pressure-bearing flat board, be arranged on by the longitudinal heart axle pressure-bearing and put down
Lower floor's seesaw on plate, two upper strata seesaws being arranged on by horizontal spindle on lower floor's seesaw, longitudinal heart axle
In the longitudinal semi-circular section elongated slot for being arranged on longitudinal semi-circular section elongated slot on pressure-bearing flat board top and lower floor's seesaw bottom, under making
Layer seesaw can be swung using longitudinal heart axle as axle center, and the horizontal spindle is arranged on the horizontal semicircle on lower floor's seesaw top
In section elongated slot and the horizontal semi-circular section elongated slot of two upper stratas seesaw bottom, make upper strata seesaw using horizontal spindle as axle center
Can swing；It is respectively arranged between pressure-bearing flat board and lower floor's seesaw between lower floor's seesaw and upper strata seesaw
The spring of auxiliary balance.
The two ends of described longitudinal heart axle are fixedly connected with by heart axle location-plate and lower floor seesaw respectively, and are installed in and are held
Lower floor's seesaw limiting plate longitudinal spacing of locating back front and back end；Described horizontal spindle is fixed by screws in upper strata seesaw
In the horizontal semi-circular section elongated slot of bottom, and it is installed in the upper strata seesaw limiting plate transverse direction limit of lower floor's seesaw left and right ends
Position.
The operation principle of the balancer is：
The pressure-bearing flat board of the seesaw balancer is arranged on hydraulic press main cylinder piston-rod upper end, by four moulds pair that work
Title is arranged on the upper strata seesaw of the seesaw balancer, when forcing press master cylinder picking-up balancer is up, to the core rod of mould
Pressurization, when four core rod stress are different, lower floor's seesaw and upper strata seesaw in the presence of power difference around mandrel swings, finally
Reach that active force is essentially equal on each core rod, balancer is in poised state, reach the purpose of level specific pressure compacting.
The utility model is simple in construction, low manufacture cost, effectively overcomes the shortcoming of existing fluid communication device formula balancer.
