In the precision field of mold manufacturing, a highly adaptable and high - performance cold forming main mold push tube is of utmost importance. Our customized cold formingmain mold push tube is specifically designed to meet the needs of various complex molds, dedicated to enhancing your production efficiency and product quality.
I. Meticulous Material Selection for Exceptional Quality
1.The basic materials we select are high - quality die steels, such as SKD61 and H13. SKD61 has good toughness and high - temperature strength, enabling it to operate stably in complex environments like die - casting and injection molding. H13, with its excellent balance of hardness and toughness, can effectively resist impacts and friction, ensuring the long - term durability of the push tube.
2.For special working conditions, we offer customized alloy addition services. To enhance corrosion resistance, chromium and nickel elements are added; to improve high - temperature performance, molybdenum, vanadium, etc. are included. Through precise alloy ratios, the push tube can maintain optimal performance under various harsh conditions.
II. Exquisite Process for Precision and Reliability
1. Precision Forging: The raw materials are forged multiple times. The upsetting and drawing - out processes make the grain structure inside the steel more uniform and dense. This not only improves the strength and toughness of the material but also optimizes its machinability, laying a solid foundation for subsequent processing. After forging, the material performance is enhanced by approximately 20% compared to the original state.
2. CNC Precision Machining: Advanced CNC equipment is used to perform operations such as turning, drilling, and grinding on the forged steel. During turning, with the help of high - precision tools and the CNC system, the outer diameter dimensional tolerance is controlled within ±0.005mm; laser positioning is used for drilling to ensure the positional accuracy of the internal runner reaches ±0.01mm; mirror grinding makes the surface roughness reach Ra0.1 - 0.2μm, greatly reducing friction and improving demolding efficiency.
3. Precision Heat Treatment: The vacuum quenching and tempering process is adopted to precisely control heating, holding, and cooling. The quenching temperature is controlled between 1020 - 1050℃, and tempering is carried out multiple times at 580 - 620℃ to eliminate quenching stress and achieve the best balance between hardness and toughness. The hardness of the push tube is stably maintained at HRC48 - 52.
4. Personalized Surface Treatment: According to different requirements, surface treatment options such as nitriding and hard chromium plating are provided. The high - hardness nitride layer formed by nitriding significantly enhances wear resistance and corrosion resistance; hard chromium plating makes the surface of the push tube smooth, reducing the friction coefficient and enhancing rust - prevention ability. For special requirements, PVD coating treatment can also be carried out.
III. Overcoming Technical Challenges to Ensure Product Quality
1. Ultra - High - Precision Dimensional Control: The customized main mold push tube has extremely high requirements for dimensional accuracy. Tool wear, cutting - heat deformation, and machine tool vibration during processing can all affect accuracy. Therefore, we adopt a real - time monitoring system to dynamically monitor the processing dimensions and automatically compensate and adjust through the CNC system to ensure minimal dimensional tolerances.
2. Complex Internal Runner Processing: With the innovation of mold design, the shapes of the internal runners of the push tube are diverse and complex. For special - shaped runners, we introduce five - axis linkage machining centers and special processing technologies such as electrical discharge machining and electrolytic machining. At the same time, simulation software is used for simulation analysis to optimize processing parameters and ensure the accuracy and surface quality of the runner.
3. Guarantee of Material Performance Consistency：The customized push tubes have diverse specifications and shapes, and it is challenging to ensure the material performance of each push tube is consistent. Different batches of raw materials, processing differences, and uneven heat treatment can all lead to performance fluctuations. We establish a strict quality control system to strictly control the whole process from raw material inspection to final product inspection, ensuring stable and consistent performance.
IV. Operation and Maintenance Guidelines for Extended Service Life
1. Installation Guidance: Before installation, ensure that the surface of the mold mounting base is flat and clean. Measure the mating dimensions of the push tube and the mounting base with high - precision measuring tools to ensure they meet the design requirements. During installation, use special tools to slowly and smoothly press it in, avoiding knocking and collision to prevent the push tube from deforming or being damaged. After installation, check the installation position and perpendicularity to ensure good coordination with other components.
2. Demolding Key Points: After the product is formed, the push tube is driven to demold through the ejection system of the mold. According to the shape, size, and material of the product, reasonably adjust the ejection speed and pressure. For thin - walled and fragile products, low - speed and low - pressure ejection is adopted; for products with complex structures, multiple or segmented ejections may be required. Closely observe the movement of the push tube during operation. If there are any abnormal situations such as jamming or skewing, stop immediately to troubleshoot.
3. Maintenance and Upkeep: Clean the residual materials on the surface of the push tube in a timely manner after each use. Wipe it with a special cleaning agent and a soft cloth to avoid scratching. Clean the internal runner with high - pressure air or special equipment. Regularly lubricate the moving parts of the push tube, applying an appropriate amount of high - temperature - resistant and wear - resistant lubricant every 200 - 500 hours. Conduct a comprehensive inspection every 3 - 6 months, measure the dimensions, check the surface and internal runner, and repair or replace problem components in a timely manner to ensure that the push tube is always in good working condition.
