Injecting head promotion is proceeded to pouring position above shoes mould by head forward-reverse oil cylinder；3. injection stage；Spiral shell is pushed by injection cylinder
Raw material is poured into shoes mould by bar from the intracavitary extrusion of injection head, and raw material vulcanizes in shoes mould or forms after cooling.
Each technological actions such as preformed, head advance and retreat, the injection of injection machine for sole currently on the market are using hydraulic
Control mode, to can guarantee that injection head carries out quantitative injection in the different segmentations of shoes mould, using electro-hydraulic proportional valve or servo electricity
The output oil mass of machine control oil pump is to control the different astern speeds and different injection speeds of head, but due to hydraulic system
Itself is influenced to cause head cannot be accurately in the presence of the intrinsic characteristic such as pulsation, inertia and by oil temperature, oil pressure etc. are more multifactor
Each injection position of shoes mould is rested on, injection speed cannot be controlled accurately, and Repetitive controller precision is not high, therefore in production
A possibility that substandard products occur is very high, to guarantee that the quality of product needs to reserve certain surplus when setting doses to expend
Certain additional doses increases production cost.
