What are the components of injection mold

Injection mold is an important tool for the production of plastic products, and its components cover many aspects, which we will introduce one by one below.

The material choice of injection mold is the key. Commonly used mold materials include H13 steel, P20 steel, etc. These materials have good wear resistance, corrosion resistance and high temperature properties, and can meet the requirements of injection molding. In addition, in order to improve the life of the mold and reduce wear, some manufacturers will also use tungsten carbide, ceramics and other high-performance materials.

The processing technology of injection mold is very critical. In general, the mold manufacturing process includes design, processing, inspection and other links. In the design stage, it is necessary to determine the structure and design details of the mold according to the shape, size, material and other factors of the product. In the processing stage, it is necessary to create qualified molds by cutting, grinding, EDM and other means. In the inspection stage, it is necessary to check the accuracy, surface quality and structure of the mold to ensure that the quality of the mold meets the requirements.

In addition to the material and processing technology, the structural parts of the injection mold are also very important. The structural parts include guide post, thimble, cylinder, etc., which play the role of guiding, ejecting, driving and so on during the injection molding process. The guide column can ensure the accuracy and stability of the mold, the thimble can push the product out of the mold smoothly, and the oil cylinder can provide power to drive the opening and closing of the mold. The selection and use of these structural parts have a direct impact on the quality and efficiency of injection molding.

The electrical parts in the injection mold are also a part that cannot be ignored. Electrical components include solenoid valves, electrical components, etc., which control the action of the mold and the execution of the program. The solenoid valve can control the opening and closing of the mold, injection, pressure holding and other actions, and the electrical components can provide signals to control the execution of the program. The selection and use of these electrical components have an important impact on the automation and accuracy of injection molding.

In addition to the above aspects, injection molds have other components, such as cooling systems, drainage, and so on. The cooling system can control the temperature of the mold within a suitable range to ensure the efficiency of injection molding and the quality of the product. The drainage system can discharge the water in the mold to avoid affecting the use of the mold. The rational design and use of these systems play an important role in improving the service life and stability of injection molds.
