Whyneed SMED Quick Die-Change System:
With the increasing competition in themarket, plastic products faster replacement, the coexistence of more and morevarieties, many varieties, small batch production, Francis production willbecome the mainstream, especially for the automotive industry supportingenterprises, whether it is or will be interior trim, parallel, for differentmodels of complete. Provide qualified products. Therefore, the time interval ofthe mould replacement will become increasingly short, that is to say the mouldreplacement frequency will be higher and higher, the corresponding injectionmolding machine downtime will greatly increase, seriously affect the productionefficiency and machine utilization rate, the delivery period is prolonged,large investment can not be effectively return. This situation has caused thedomestic production and use of injection molding machine manufacturersattention, in the injection molding processing automation if not effectivelysolve the problem of quick die change, other production automation degree highis difficult to fully To improve the utilization rate of equipment, improveproduction efficiency, the whole set of equipment can only be regarded asstrong, flexible response to "lame". And this problem in Westernindustrialized countries has been basically solved, namely: the quick diechange system.
(1)Pull type rotary machinery
This is a quick die change system early,typical products from the Swiss company "Staubli". The characteristicsof the system are: die clamping back center, suitable for small andmedium-sized injection molding machine. The mechanical structure is morecomplex, in the rear part of the mould clamping force back center. Theadvantages of this system are: die around completely open, no any clampingelement for external pipe plug. The system's weakness is: die back shall beinstalled with uniform clamping mechanism. The clamping force and no backaround, wear large mold deformation work, clamping parts of the component wearserious, no clamping element state feedback signal supply system installation,host. Maintenance is difficult, not suitable for retrofitting existingequipment.
(2) Hydraulic press plate
This is the most widely used rapid diechange system, typically from Enerpac, US Aerostar, Pascal from Japan.
Now in Ningbo China,we R&Dourselves,and develop our own hydraulic press plate,widely applied in injectionand stamping/punching/die casting facilities during the process of diechange/mold change.
(3) Magnetic chuck type
This is the rapid development in recentyears, American industrial developed countries is widely accepted and adoptedthe quick die change system, typical products from Italy TECNOMAGNETE(tecnomagnet) company, has more than 10 years of development of this product,production and application experience of nearly 10000 system is applied to allover the world, especially for the automotive industry supportingmanufacturers. In recent years, the Swiss Staubli company and Pascal company ofJapan also started from the traditional hydraulic steering system for molddevelopment and sales force system. The system is characterized by structureand control is very simple, without any mechanical clamping elements andmovement in the mold plate and the suction pole on the contact surface, nomatter is the heart or peripheral, all permanent magnetic clamping, injectionmolding machine is suitable for various types and specifications. Theadvantages of this system are: convenient installation, hydraulic and fullyelectric injection molding machine is suitable for various specifications,clamp Force from the permanent magnetic materials, without electrical work, aclamping state real-time signal feedback to the host, to ensure absolute safetyclamping; full contact surface due to uniform clamping force, mold indeformation and wear a small, precision injection molding and good consistency,prolong service life of moulds; die around without any actuator the utility,periphery pipeline. Without mechanical movement of the system, mechanical,electrical transient electrical, therefore in use without maintenance, life isvery long. The weaknesses of this system is: magnetic template thickness (54mm54mm) has a certain effect on the small mould opening stroke.
