Abstract
The completion of this subject 250g small injection molding machine
hydraulic system. Plastic injection molding is a thermoplastic products,
processing equipment, it will heat melting plastic particles, high speed
injection mold cavity, after some time packing, cool molding for the plastic
products. This design was completed for the following design elements:
principles and theoretical study of injection molding and injection molding
process analysis; SZ-250 injection molding machine, low power and highly
efficient energy-saving hydraulic system design, schematic drawing of work;
hydraulic structure design and drawing. Hydraulic cylinder design, the
cylinder block and cylinder head connection with external half-ring, piston rod
and piston screw thread used to connect modular structure. The structure of
hydraulic control unit integrated with block block design, made of 6-sided
universal manifold block (Manifold). This design uses vertical installation of
the bell jar, pump the shaft through the pump flange to achieve the connection
with Bell, Bell again and vertical motors with flange connection, relying on
the only bell-shaped hood hydraulic pump and motor mouth to ensure
concentricity.
