Kakšna so načela in mehanske strukture strojev za brizganje plastike?

First, let's understand the principle of plastic injection molding machine. Plastic injection molding machine is based on the principle of melt injection, that is, solid plastic material is heated and melted, and then injected into the mold by pressure to finally form the desired plastic product. The whole process can be divided into the following key steps: plastic feeding and melting, injection molding and cooling, Odpiranje in zapiranje plesni ter odstranjevanje izdelka .

Glede na mehansko strukturo je stroj za brizganje plastike običajno sestavljen iz naslednjih glavnih delov:

4. Šoba: Šoba je komponenta, ki v šobo povezuje ogrevalni valj in kalup ., staljena plastika se pritiska in spiralno premakne, da še izboljšata enotnost in pretočnost plastike .

5. Mold: The mold is a key component used for plastic injection molding. It usually consists of two half molds and can be designed and customized according to the shape and size of the required product. The mold contains a cavity for receiving the injected molten plastic and forming the required product shape.

6. hidravlični sistem: Hidravlični sistem se uporablja za zagotavljanje tlaka in moči, ki jo zahteva stroj za oblikovanje vbrizgavanja . Vključuje komponente, kot so hidravlična črpalka, hidravlični cilinder in krmilni ventil, ki nadzoruje tlak in gibanje, da med vbrizgavalnim procesom.}}}}}
