The injection mold manufacturing process is a complex and delicate process, which involves multiple stages to ensure the precision, durability and production efficiency of the mold. The following are the detailed steps of the injection mold manufacturing process:
Preliminary design stage:
According to the needs and design of the product, the structural design of the mold is carried out. This includes cavity layout, pouring system design, demoulding mechanism design, cooling system design, etc.
Use CAD software for design, and fully consider factors such as product shape, size, precision requirements, materials, etc.
Mold material selection:
According to the use requirements and processing technology of the mold, select appropriate mold materials. Commonly used mold materials include steel, aluminum alloy, copper alloy, etc. Steel is suitable for the processing of high-precision and long-life molds due to its good wear resistance and toughness.
Mold part processing:
Rough processing: Rough processing of mold parts, such as milling, planing, drilling, etc., removes excess material and preliminarily forms the shape of mold parts.
Semi-finishing: On the basis of rough processing, semi-finishing is carried out to further correct the shape and size of mold parts and prepare for finishing.
Finishing: Fine processing of mold parts, such as grinding, turning, milling, etc., to achieve the final precision requirements of mold parts. This stage may also involve precision processing technologies such as mirror sparks and slow wire walking.
Assembly and debugging:
Assemble the processed mold parts and debug them to ensure that the overall performance and precision of the mold meet the requirements.
During the assembly process, it is necessary to ensure the matching accuracy and position accuracy between the parts, and at the same time test the assembled mold to check for leakage, jamming and other problems.
Delivery and acceptance:
After assembly and debugging, the qualified mold is packaged and delivered after sorting and cleaning.
During the acceptance stage, the appearance, size, accuracy, assembly, etc. of the mold need to be fully inspected to ensure that the quality of the mold meets the requirements. At the same time, the corresponding technical documents and qualification certificates need to be provided.
In summary, the injection mold manufacturing process includes preliminary design, mold material selection, mold part processing, assembly and debugging, and delivery and acceptance. Each stage needs to strictly follow the process and specifications to ensure the quality and performance of the mold.
