What are the structural components of injection mold processing?
Injection mold processing is composed of two parts, moving mold and fixed mold, the moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the moving mold and the fixed mold are closed to form the casting system and cavity, and the moving mold and the fixed mold are separated when the mold is opened to remove the plastic products.
Injection molds are divided into thermosetting plastic molds and thermoplastic molds according to molding characteristics; According to the molding process, it is divided into plastic transfer mold, blow molding mold, casting mold, thermoforming mold, hot pressing mold (compression molding mold), injection mold, etc., of which the hot pressing mold can be divided into three types: overflow, semi-overflow, and non-overflow by overflow, and the injection mold can be divided into two types: cold runner mold and hot runner mold by pouring system; According to the loading and unloading mode, it can be divided into two types: mobile and fixed.
Injection mold processing is a tool for the production of plastic products; It is also a tool to give plastic products a complete structure and size. Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to the heated melted plastic injected into the mold cavity by injection molding machine at high pressure, and the molded product is obtained after cooling and solidification.
Injection mold processing
Although the structure of the mold may vary depending on the variety and performance of plastics, the shape and structure of plastic products, and the type of injection machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature regulation system, forming parts and structural parts. Among them, the pouring system and molded parts are the parts that are in direct contact with the plastic, and change with the plastics and products, which is a complex and large part of the plastic mold that requires high processing finish and precision.
The gating system refers to the part of the flow channel before the plastic enters the cavity from the nozzle, including the main channel, cold material cavities, manifolds and gates. Molded parts refer to various parts that make up the shape of the product, including moving molds, fixed molds and cavities, cores, forming rods and exhaust ports.
Injection mold processing is composed of two parts, moving mold and fixed mold, the moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. The mold is moved during injection molding
1. When disassembling the mold, avoid bumps and water, and move smoothly.
2. Spray hot mold, and then spray a small amount of mold release agent
3. To carry out a comprehensive inspection of the mold and carry out anti-rust treatment: carefully wipe the moisture and debris in the cavity, core, ejection mechanism and row position, etc., and spray the mold rust inhibitor and apply butter.
In the continuous working process of the mold, mold maintenance is required due to the wear of parts, lubricant deterioration, water leakage, crush injury of plastic materials and other problems caused by the movement process.
Daily mold maintenance generally includes the following aspects:
1. Regular rust removal (appearance, PL surface, mold cavity, core, etc.)
2. Re-add lubricant regularly (ejection mechanism, row position, etc.)
3. Regularly replace wear parts (tie rods, bolts, etc.)
4. Other points to pay attention to
The lower mold maintenance of the mold needs to be professionally tested and protected by professional maintenance personnel after the mold is removed and the mold cavity, ejector pin, etc. are carried out.
