technical field

The utility model relates to the technical field of injection molding machines, in particular to a vertical injection molding machine with an upper mold that automatically rotates.

Background technique

Vertical injection molding machine usually consists of injection system, mold clamping system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system, etc. The injection system is one of the most important components of the injection molding machine. Generally, there are three main forms: plunger type, screw type, and screw pre-molded plunger injection type. The most widely used is the screw type. Its function is that in a cycle of the injection molding machine, a certain amount of plastic can be heated and plasticized within a specified time, and then the molten plastic can be injected into the mold cavity through the screw under a certain pressure and speed.

We all know that a traditional single injection molding machine can only mold injection molded parts of a single size and type, such as cups.
