Optimization Design for MA5300 Injection Molding Machine’s Clamping Unit’s Hydraulic System

Abstract:

Focusing on PET perform molding features, working principles of MA5300 Injection Molding Machine’s clamping unit’s hydraulic system has been analyzed in this paper. Based on previous hydraulic system, magnetic exchange valve has been added on the demoulding hydraulic circuit, demolding speed has been fastened; energy accumulator has been added on the control circuit so as to stabilize controlled oil-source, improve time of opening and clamping mould and response speed. In addition, common one-way valve in core oil circuit is replaced with hydraulic control one-way valve, in order to realize pressure maintaining function; hydraulic insurance structure is changed into inner circulation, and two-way cartridge valve is used as security valve, so as to realize faster response, and largely improved equipment security. Through adopting common hydraulic components, under the premise of limited increasing cost, the injection molding cycle for PET perform product has been reduced, and enterprise’s productivity has been improved.
