Prionsabal oibre an mheaisín mhúnlú insteallta

Meaisín múnlaithe instealltatugtar meaisín insteallta air freisin, arb é an príomh-threalamh múnlaithe a úsáideann múnlaí múnlaithe plaisteacha chun plaistigh teirmeaplaisteacha nó teirmeaséadaithe a dhéanamh i cruthanna éagsúla táirgí plaisteacha. Lena n-áirítear ingearach, cothrománach agus uile-leictreach. Is féidir leis an meaisín múnlaithe insteallta an plaisteach a théamh agus ardbhrú a chur ar an plaisteach leáite chun é a instealladh chun an cuas múnla a líonadh.

Tá prionsabal oibre réasúnta cosúil leis an meaisín múnlaithe insteallta agus an steallaire a úsáidtear le haghaidh instealladh. Is próiseas é ina ndéantar an plaisteach stáit leáite phlaisteach (ie, staid sreafa slaodach) a instealladh isteach sa chuas múnla dúnta trí sá an scriú (nó an plunger), agus faightear an táirge tar éis soladú agus múnlú.

Ar dtús, cuir plaisteach gráinneach nó púdraithe i mbairille anmeaisín múnlaithe insteallta. Leádh an plaisteach leis an rothlú of the screw and the outer wall of the barrel. Then the machine closes the mold and moves the injection seat forward, and the nozzle is close to the gate of the mold. , And then pass the pressure oil through the injection cylinder and push the screw forward. Thus, the molten material is injected into the closed mold with a lower temperature at a high pressure and a faster speed. After a certain period of time and pressure holding (also called pressure holding), cooling, solidification and molding, the product can be opened and the product can be taken out. (To ensure that the product has a certain density and dimensional tolerances, it is the purpose of maintaining pressure to supplement the material in the cavity to avoid the reflux of the melt in the cavity). Plasticization, injection and molding are the basic requirements of injection molding. The prerequisite for the quality of the formed product to be achieved and guaranteed is plasticization, and there is a high pressure response in the cavity (20-45MPa is usually the average pressure in the cavity), so the meaisín múnlaithe insteallta has enough Large clamping force. It can be seen that the injection device and clamping device of the key part of the meaisín múnlaithe insteallta.
