Plastic injection molding machine from China, China plastic injection molding machine, injection molding machine of plastic, plastic injection molding machine in China, China machine of plastic molding
Plastic injection molding machine assembling parts:
Plastic injection molding machine main function is cycling it from melt the thermoplastic material ,then injection, then pressurize and last cooling ,then got the products. There are the normal parts assembling: Hydraulic system, injection system, mold system and clamping system.
Plastic injection molding machineincluding hopper, rotating screw and nozzle, injection system main function is to responsibility feeding material, pressure, venting, melt, injection and pressurize.
- Hopper from plastic injection molding machine: particle thermoplastic material install inside the hopper, then feed to the barrel and screw by the weight pressure
- Barrel from plastic injection molding machine: the barrel loaded the rotating screw and heated by the heating ring.
- The rotating screw from plastic injection molding machine: It function is for pressure, melting and delivery the material, and it formed with feed zone, transition zone and metering zone.
When the screw outside diameter is stable, the depth of rotating screw’s thread will be cut down from feed zone to metering zone, and then the material will be melt by it. The heating ring outside the barrel could keep the material with melting status. Generally, one set of plastic injection molding machine will have 3 zones or more heating rings for keeping the temperature, the heating rings with different temperature due to it in different zones.
- Nozzle from plastic injection molding machine: the nozzle connected with barrel and main spurge bushing of the mold, and made the apace with sealing.
The nozzle temperature should be the same with the plastic material melting temperature or a little lower than it, it could suggest by the material supplier, because they have more professional ideas.
When the barrel in a status of full material and will be injection, the head of the nozzle should be in a correct position. When clean the barrel, should remember to backward the barrel, should take part of the spurge, then the material will falling directly.
Plastic injection molding machine could supplier a force for open and close the mold, rotating and drive the screw, push the ejector pin and made the core moving. This step need the pump, valve and motor, connector and so on parts cooperation.
Control system could promise the equipments keep working for a long time, could administrate and control the date like temperature, pressure, injection speed and the screw speed, position, and the hydraulic system status.
Plastic injection molding machine function of the clamping unit:
- Support the mold – Supporting the mold together with the leading it opening and closing, then it required the clamping system have enough force to moving the movable platen.
- Clamping the mold – When the melting plastic material is injection to the mold cavity should keep the mold with sealing status, so need it to clamping the mold.
- Provide ejection – When the products molding, mould opening, need it provide ejection force.
