Working principle
The injection molding machine pushes the plastic particles forward through the rotation of the screw.，and heated and melted in a heating cylinder。When the plastic reaches a certain molten state，The injection device of the injection molding machine injects molten plastic into the mold cavity at high pressure。during the injection，The movable mold and the fixed mold of the mold are tightly closed，Provide sufficient clamping force，Prevent plastic spillage。
The mold is mainly composed of two parts: the movable mold and the fixed mold.。The movable mold is installed on the moving platen of the injection molding machine，The fixed mold is installed on the fixed template。When the injection molding machine closes the mold，The movable mold and the fixed mold are closely matched，Form a closed mold cavity。
The pouring system is an important part of the mold，including main channel、Runners and gates, etc.。The main channel is the channel that connects the nozzle and runner of the injection molding machine.，Introducing molten plastic into the mold。Split channels distribute plastic evenly to each cavity。The gate is the entrance for plastic to enter the mold cavity.，Its shape and size have a significant impact on plastic flow and product quality。
Temperature control system is used to control the temperature of the mold，Make sure the plastic cools and solidifies at the right temperature。Molded parts are the parts that are in direct contact with plastic，Determines the shape and size of the product。Structural parts play the role of supporting and fixing the mold。Learn more about the injection molding process
