The role of fully automatic injection molding machine pressure switch

by:FUHONG     2020-09-28
When fully automatic injection molding machine injection process is complete, the cavity is filled with melt. At this time, the location of the injection screw has been moved to the front. Due to the effect of cooling of the fully automatic injection molding machine mould at low temperature, the melt injection cavity contraction. In order to produce high quality products, prevent the reverse flow of melt in cavity, compensate the shrink of the product, to suppress the injection pressure cylinder. Must maintain a certain pressure, and constantly push the screw, the melt in die pressure, until the gate melt cooling seal. At this point, the effect on the melt pressure screw called maintain pressure, also known as the secondary stress. In keeping the pressure, the screw will move forward a little bit because of the feed. When automatic injection molding machine molten material in the cavity door lose the possibility of a return, internal pressure can be deleted ( Close the high-pressure hydraulic cylinder can also be deleted) ( The door closed) Oil cylinder, and injection can be used for cooling and death shape products. All the above is to introduce the content, hope to be of help. If you want to learn more knowledge, you can visit our website, we will provide you with more professional information.
