It sets.
Background technology
Existing depth cavity mould, product package power is big, and mold die sinking action often has some setbacks, because push plate can not with male template
Die sinking, it is that smooth can not be vented since exhaust structure is unreasonable, while causing injection pressure excessive to cause this phenomenon, pressure
Conference reduces the service life of injection molding machine movable device, Hydraulic System for Injection Moulding Machine can be made unstable for a long time, also easily cause flash, excessively fills
It fills out, the bad phenomenons such as stress concentration near cast gate.
That there is also cooling effects is poor for existing depth cavity mould, causes product starved, influences the intensity of product, to influence to produce
Moral character energy.It is excessively high that cooling effect difference also causes mold temperature, and high temperature makes machinery generate thermal deformation, and each section uses in injection molding machine
Material is different, therefore the different moving component of coefficient of thermal expansion causes action to be lost because that its fit clearance becomes smaller is stuck in Hydraulic Elements
Spirit, the transmission accuracy for influencing hydraulic system, lead to component working degradation, also lead to the increase of bad products.High temperature is also led
Rubber seal deformation, many places of injection molding machine is caused to have rubber ring, injection molding machine temperature liter is excessively high so that rubber seal is deformed, and add
Fast ageing failure reduces sealing performance and service life, causes to leak.
