Working principle and application of right angle injection molding machine
Date：2024-11-15
Working principle of angle injection molding machine
Angle injection molding machine is a special structure of injection molding machine, whose injection direction is at a certain angle to the clamping surface, usually 90 degrees. This design gives corner injection molding machines unique advantages in certain specific applications. The basic workflow includes the following steps:
1. Plasticization
Plastic particles enter the heating cylinder through the hopper and are pushed and melted into a viscous state by the screw under high temperature and pressure.
2. Injection
Molten plastic is injected into the mold cavity under high pressure by the push of the screw. Due to the angle between the injection direction and the mating surface, angle injection molding machines can more effectively fill the corners and details of complex molds.
3. Maintain pressure
After the injection is completed, the screw maintains a certain pressure to ensure that the plastic can fully fill all corners of the mold cavity and compensate for the shrinkage caused by cooling.
4. Cooling
Plastic cools and solidifies inside the mold, forming the shape of the final product. The duration of the cooling process depends on the thickness and material properties of the product.
5. Mold opening and ejection
The mold is opened, and the ejector pin pushes the finished product out of the mold, completing one production cycle.
3、 Structural characteristics of angle injection molding machine
1. Injection system
The injection system of angle injection molding machines usually adopts a screw design, where the screw rotates inside the heating cylinder, heats and melts plastic particles, and injects them into the mold. The design of the screw can be adjusted according to different plastic materials to achieve the best plasticizing effect.
2. Mold closing system
The mold clamping system consists of templates, pull rods, and clamping mechanisms. The unique design of the clamping system of the angle injection molding machine enables rapid opening and closing of the mold, improving production efficiency. At the same time, the mold clamping system is also equipped with safety protection devices to ensure the safety of operators.
3. Hydraulic system
The hydraulic system provides power for various actions of the injection molding machine, including mold closing, injection, pressure holding, and ejection. The control accuracy of hydraulic systems directly affects the quality and production efficiency of products.
4. Electrical control system
The electrical control system is responsible for controlling and managing the entire injection molding process, including temperature control, pressure control, action control, etc. Modern electrical control systems usually use PLC (Programmable Logic Controller) for control, which has the characteristics of high automation and intelligence.
5. Heating/cooling system
The heating system is used to heat plastic above its melting point to achieve a flowing state; The cooling system is used for the cooling of molds, allowing plastic products to quickly solidify and form. The temperature control accuracy of heating and cooling systems has a significant impact on the quality of products.
