The molding machine, also known as the unpacking machine, refers to the automatic unpacking, forming, and bending of the lower bottom flap. At present, the lower part of the tape is pasted, and the box board which is stacked into cardboard is opened, and the bottom of the box is folded according to a certain procedure, and sealed with a tape and then delivered to the special equipment of the boxing machine. The automatic carton forming machine and automatic cartoning machine are the assembly line for automatic unpacking of large-volume carton, automatic folding of the lower cover and automatic sealing of the bottom tape. The machines are all controlled by PLC+ display, which is very convenient for operation and is essential for automated scale production. device of.
The working principle of the molding machine is similar to that of the syringe for injection. It uses the thrust of the screw (or plunger) to inject the plasticized molten state (ie, the viscous flow state) into the closed cavity. The process of obtaining the product after curing and setting.
Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding - melt plasticizing - pressure injection - filling mold cooling - mold extraction. After removing the plastic part, the mold is closed again and the next cycle is performed.
