Working principle of injection mould with consistent basic structure
Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and accurate size. Injection mold is a part that gives shape and size to plastics during molding. Although the structure of the mold may vary greatly due to different types and properties of plastics, shapes and structures of plastic products, and types of injection machines, the basic structure is the same.
Injection molding is a processing method used in the mass production of some complex shaped parts. Specifically, the heated melted plastic is injected into the mold cavity by the injection molding machine under high pressure, and the molded products are obtained after cooling and curing. Among them, the gating system and molding parts are the parts that directly contact with the plastic and change with the plastic and products. They are the most complex parts in the plastic mold with the greatest change, and require the highest processing finish and precision.
The plastic is first heated and melted in the heating barrel at the bottom of the injection machine, and then driven by the screw or plunger of the injection machine, enters the mold cavity through the nozzle of the injection machine and the gating system of the mold. The plastic is cooled, hardened, molded, and demoulded to obtain products. Its structure is usually composed of forming parts, gating system, guiding parts, pushing mechanism, temperature regulating system, exhaust system, supporting parts, etc.
Plastic mold steel modules are usually used as manufacturing materials, and the commonly used materials are mainly carbon structural steel, carbon tool steel, alloy tool steel, high-speed steel, etc. The injection molding processing method is usually only applicable to the production of hot plastic products. The plastic products produced by the injection molding process are very extensive. From daily necessities to various complex machinery, electrical appliances, transportation tool parts, etc. are all molded by injection molds. It is the most widely used processing method in the production of plastic products
Injection molding is a manufacturing process used to produce a wide range of plastic parts and products. The injection mould, which is a critical component of the injection molding machine, has a consistent basic structure and works on a simple yet effective principle. Here is an overview of the working principle of the injection mould with a consistent basic structure:
The injection mould is designed with two main halves, the core and cavity. The core and cavity are placed together to form the mould cavity. The molten plastic material is then injected into the cavity through a small opening in the injection mould.
The injection mould works on the principle of pressure and heat. The plastic material is heated to a melting point and then injected into the mould cavity under high pressure. Once the molten plastic is injected into the cavity, it takes on the shape of the mould cavity as it cools and solidifies.
The mould cavity is designed to be slightly larger than the final product size, allowing for shrinkage during the cooling and solidification process. The mould cavity is also designed to allow for the easy removal of the finished product from the mould.
The injection mould with consistent basic structure has a simple design that allows for easy assembly and disassembly. The core and cavity are designed to be interchangeable, allowing for the production of different parts using the same mould.
The injection mould is also designed to be durable and withstand the high temperatures and pressures involved in the injection molding process. The mould is typically made from high-quality materials, such as hardened steel, to ensure long-lasting performance.
In conclusion, the injection mould with consistent basic structure works on a simple yet effective principle of pressure and heat. The molten plastic material is injected into the mould cavity under high pressure and takes on the shape of the mould as it cools and solidifies. The injection mould is designed to be durable and withstand the high temperatures and pressures involved in the injection molding process, and its simple design allows for easy assembly and disassembly.
