Static pressure Moulding Line
Product Detail:
Static pressure moulding technical refers to airflow with hydraulic multi-piston squeeze compaction technology, according to the difficulty of compaction, can choose only hydraulic multi-piston squeeze compaction or airflow and hydraulic multi-piston squeeze compaction. Static Pressure has following advantages.
● High ability for compaction sand, rigid and dense mould, suitable to manufacture of complex castings.
● Dimensional stability and better surface roughness ,high efficiency of moulding
● Mould plate with high rate of utilization. Good working condition and labour saving
General Process ：
Layout Example
1 Process of molding machine
A. Empty Flask is indexed into the molding machine molding station
B. Pattern bolsters rotate or shuttle
C. The lifting cylinder rises, and the formwork, sand box and pre-sand frame rise
D. Quantitative sand adding
E. Move the sand bucket out while moving the multi-contacts in and clean the upper surface of the pre-sand frame
F. The lifting cylinder goes up again to top tight
G. Air pre-compacting and compaction
H. The lifting cylinder falls down while drafting
