Horizontal injection molding machine The working principle of plastic injection molding machine is a common injection molding equipment, which is widely used in the production industry of plastic products. It heats, melts and injects the plastic materials into the mold through the cooperation of the control system and various mechanical parts, and finally obtains the required injection products.
The working principle of horizontal injection molding machine can be simply summarized as the following steps:
1. Feeding: First, input the prepared plastic particles or granular materials into the feeding device of the injection molding machine through the feeding port. The feeding device usually includes a hopper and a screw, which will push the plastic material from the hopper to the heating cylinder of the injection molding machine.
2. Heating and melting: Once the plastic material enters the heating cylinder, the injection molding machine will raise the temperature in the heating cylinder to the appropriate melting temperature through the heating system. The heating methods commonly used include electric heating and oil heating. When the plastic material is heated to a high enough temperature, it will gradually melt and become viscous.
3. Injection: Once the plastic material has completely melted and reached the required melting state, the injection molding machine will inject it into the mold. The injection molding machine is usually equipped with an injection system, including an injection cylinder and a piston. The piston will push forward to press the molten plastic material from the injection cylinder into the injection port of the mold.
4. Cooling and curing: After the injection molding machine injects molten plastic materials into the mold, the cavity in the mold will be cooled and cured. The cooling time will be determined according to the size and requirements of injection molded products. Once the plastic material has solidified, the mold will open and the finished product will be taken out of the mold.
The working principle of horizontal injection molding machine is relatively simple and intuitive, but many factors need to be considered in actual operation, such as temperature control, pressure control, injection speed and mold design. The reasonable adjustment and control of these factors will directly affect the quality and production efficiency of injection molding products.
Injection molding machine manufacturer To sum up, the horizontal injection molding machine realizes the production of plastic products by heating and melting plastic materials and injecting them into the mold. The process is simple and efficient, and is widely used in various fields, such as daily necessities, auto parts, electronic products, etc. With the continuous development and innovation of injection molding machine technology, horizontal injection molding machine plays an important role in improving production efficiency and product quality.
