Fastener Main Die Sleeve: The Core Component in Precision Mold - Making
Material Advantages
The Fastener Main Die Sleeve is made of high - quality alloy steel, such as Cr12MoV. This type of alloy steel has excellent hardness, wear - resistance, and toughness. The high hardness ensures that it is not easily deformed or worn under high - pressure and high - friction working conditions. Good toughness enables it to withstand a certain amount of impact load, effectively extending its service life.
Manufacturing Process
1. Raw Material Inspection: Strictly control the quality of raw materials.Test the alloy steel for hardness, to ensure that the material meets the standards.
2. Forging: Use the forging process to refine the grain size, improve the distribution of metal flow lines, and enhance the comprehensive properties of the material.
3. Rough Machining: Use CNC lathes and other equipment for preliminary turning to machine out the approximate shape and size.
4. Heat Treatment: Quenching and tempering treatments are carried out to improve hardness and wear - resistance and eliminate internal stress.
5. Finish Machining: Use high - precision grinders and other equipment to finely grind the key parts such as the inner hole and outer circle of the bushing to ensure dimensional accuracy and surface finish.
6. Surface Treatment: Surface treatment processes such as hard chromium plating can be selected to further improve wear - resistance and corrosion - resistance.
Machining Difficulties
1. Dimensional Accuracy: The dimensional accuracy requirements for the inner hole and outer circle of the Fastener Main Die Sleeve are extremely high. Minor deviations may affect the assembly and performance of the mold. During the machining process, factors such as tool wear and machine - tool accuracy need to be strictly controlled.
2. Surface Quality: The surface finish requirements for the inner hole and outer circle are high. Defects such as scratches and chatter marks are likely to occur during machining, so it is necessary to reasonably select cutting parameters and machining processes.
3. Deformation during Heat Treatment: Deformation is likely to occur during the heat - treatment process. Process parameters such as heating rate, holding time, and cooling rate need to be precisely controlled.
Application Scenarios and Precautions
Application Scenarios It is widely used in mold - making for industries such as automotive parts, electronic communications, and home appliances. For example, in the molds for automotive engine cylinder blocks and mobile phone shell injection - molding, it plays a role in guiding, positioning, and supporting the mold components during the molding process.
Precautions
During installation, it is necessary to strictly follow the design requirements to ensure the assembly accuracy with other mold components and avoid the decline of mold performance due to improper installation.
During use, monitor the running status of the mold. If abnormal vibration, noise, or product quality problems are found, stop the machine in time to check whether the Fastener Main Die Sleeve is worn or damaged.
After - sales Maintenance
Regularly clean the Fastener Main Die Sleeve to remove surface oil stains, metal debris, and other impurities to prevent the impurities from entering the inner hole and accelerating wear. Regularly check the wear condition, which can be carried out by measuring the dimensions of the inner hole and outer circle and observing the surface wear marks. If the wear exceeds the specified range, repair or replace it in time. For the Fastener Main Die Sleeves that are idle for a long time, do a good job in anti - rust treatment, such as applying anti - rust oil and wrapping anti - rust paper, and store them in a dry and ventilated environment.
