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.
