How does the injection molding machine work?



According to the plasticization method, automatic injection molding machine can be divided into plunger injection molding machines and screw-type injection molding machines. And in terms of the transmission method, they can be divided into hydraulic, mechanical, and hydraulic-mechanical types.
 

● Horizontal Injection Molding Machine

This is the most common type of injection molding machine. The clamping part and the injection part are on the same horizontal centerline, and the mold is opened in the horizontal direction.
 
Its characteristics are: the body is short, easy to operate and maintain; the machine has a low center of gravity, and the installation is relatively stable; after the product is ejected, it can automatically fall under the action of gravity, and it is easy to realize fully automatic operation.
 

● Vertical Injection Molding Machine

Its clamping part and injection part is on the same vertical centerline, and the mold is opened in the vertical direction. Therefore, it occupies a small area, and it is easy to place the inserts. Moreover, it is convenient to load and unload the mold, and the material falling from the hopper can be plasticized more evenly.

However, the product is not easy to automatically fall after being ejected and must be removed by hand, which is not easy to realize automatic operation. Vertical injection molding machines are suitable for small injection molding machines. Generally, it is recommended to choose  injection molding machines which are below 60 tons (60 tons refers to the clamping force).
 

● Angel Type Injection Molding Machine

Its injection direction and the mold interface are on the same surface. It is especially suitable for flat products that are not allowed to leave gate marks in the machining center. It occupies a smaller area than a horizontal injection molding machine, but the inserts placed in the mold are prone to tilt and fall.
 

● Multi-mode turntable injection molding machine

Multi-mode turntable injection molding machine: It is a special injection molding machine with the multi-station operation. Its characteristic is that the mold clamping device adopts a turntable structure, and the mold rotates around the shaft. This type of injection molding machine gives full play to the plasticizing ability of the injection device, which can shorten the production cycle and increase the production capacity of the machine, so it is particularly suitable for large quantities of products that take a long time to cool. However, due to the large and complex mold clamping system, the clamping force of the mold clamping device is usually small, so this type of injection molding machine is often used in the production of plastic shoe soles.
