SZ-250/2000KN injection machine

SZ-250/2000KN injection machine
This design studied the hydraulic system of the SZ-250/2000KN injection    machine primarily. The injection machine includes injecting device and molding device. In the process of injection machine injection model, the plastic will be infused into the charging barral in injection molding machine, in the function of screw the plastic are turn to the plasticfying liquid posture ,then they are injected into mold antrum and become the produce, which will be crest out finally. Therefore the injection model model process of injection machine is a course as to shuttling the mold,injection seat froward leading , injection , protecting to press , defending to flow to postpone ,opening the mold , driving out manufacture piece and injection seat backspace . This is a series of action process will be complete by the hydraulic pressure system in this design . The hydraulic pressure system in this design includes other then injection ,still have every kind of value,hydraulic pump,hydraulic motor and different kinds of assistant component etc.For satisfaction with the action of injection machine design every hydraulic pressure loop,in consideration of making each action fast to
                                                     change and act steady, used a type of the doubt unite pump with vane ,design the 3-rated pressure loop and throttle timing loop,and increase many assistance in hydraulic pressure system.       In addition this designe still designed the assistant a-oil tank.The parameters of the hydraulic cylinder include every cylinder’s inner diameter, piston pole diameter, cylinder’s wall thickness,piston width,guide length and parttion cover length . In this design also have the strength checking of every cylinder and piston pole linking bolts checking adopting the open type,rectangle construction.    Key words:  hydraulic system  hydraulic cylinder  oil tank
anting guide, slide and other derivative.
