Abstract:

Injection molding machine is divided into plunger type injection molding machine and screw type injection molding machine according to the plasticizing method. According to the transmission mode of the machine, it can be divided into hydraulic, mechanical and hydraulic - mechanical (connecting rod) , Semi-automatic, manual injection molding machine.

Injection molding machine is divided into plunger type injection molding machine and screw type injection molding machine according to the plasticizing method. According to the transmission mode of the machine, it can be divided into hydraulic, mechanical and hydraulic - mechanical (connecting rod) , Semi-automatic, manual injection molding machine.

(1) Horizontal Injection Molding Machine: This is the most common type. The mold clamping portion and the injection portion are on the same horizontal center line, and the mold is opened in the horizontal direction. Its characteristics are: the fuselage is short, easy to operate and repair; machine center of gravity is low, the installation is more stable; products can be used after the top of gravity automatically fall, easy to achieve automatic operation. At present, the market of injection molding machine to use this type.

(2) vertical injection molding machine: the mold part and the injection part of the same vertical center line, and the mold is open in the vertical direction. Therefore, its small footprint, easy to install the insert, loading and unloading mold more convenient, since the hopper into the material can be more uniform plastic. But after the product is not easy to automatically drop out, you must remove the hand, not easy to achieve automatic operation. Vertical injection molding machine is suitable for small injection molding machine, usually in 60 tons (60 tons refers to the mold clamping force) the following injection molding machine used more large, medium machine should not be used.

(3) angle injection molding machine: its injection direction and mold interface on the same side, it is particularly suitable for the processing center part of the gate marks are not allowed to leave the flat products. It covers an area smaller than the horizontal injection molding machine, but the inserts placed in the mold are prone to fall. This type of injection molding machine should be used for small machines.

(4) multi-mode rotary disc injection molding machine: it is a multi-station operation of the special injection molding machine, which is characterized by a clamping device with a turntable structure, the mold around the shaft rotation. This type of injection molding machine can give full play to the plasticizing ability of the injection device, which can shorten the production cycle and improve the production capacity of the machine. Therefore, it is particularly suitable for large-volume products that require a lot of auxiliary time The production. However, due to the large and complex mold clamping system, mold clamping force is often smaller, so this injection molding machine in the plastic soles and other products in the production of more applications.

General injection molding machine, including injection device, mold clamping device, hydraulic system and electrical control system and other parts.

The basic requirements for injection molding are plasticization, injection molding and molding. Plasticization is the prerequisite for the realization and assurance of the quality of molded products, and to meet the molding requirements, the injection must ensure that there is sufficient pressure and speed. At the same time, since the injection pressure is high, a high pressure is generated in the mold cavity (the average pressure in the mold cavity is generally between 20 and 45 MPa), and therefore a sufficient clamping force must be obtained. It can be seen that the injection device and the clamping device are the key components of the injection molding machine.
