The so-called injection molding refers to the method in which the material melted by heat is injected into the mold cavity by high pressure, and after cooling and solidification, the molded product is obtained. This method is suitable for mass production of complex-shaped parts, and is one of the important processing methods.
The so-called injection molding mold refers to a device that obtains a product with a certain shape after the resin material is injected into the metal mold. Although it is not indicated in the figure, in fact, in order to control the temperature of the mold, there are cooling holes and heaters for the passage of the refrigerant (warm water or oil) on the mold.
The material that has become a melt enters the main runner, passes through the runner, and the gate is injected into the cavity. After the cooling stage, the mold is opened, and the ejector device on the molding machine will eject the ejector rod and push out the product.
