Mold Failure and Prevention Measures
Moulds are widely used in manufacturing industry to shape parts of complex configurations and obtain desired products. Mould failure is common in the production process and often has a serious impact on the production capacity and product quality. In order to improve the quality and efficiency of moulds, it is essential to analyze the reasons for mould failure and develop corresponding measures to prevent it.
At present, the common mould failure is mainly caused by mould design, mould manufature and process parameters and other reasons. Thus, the following measures need to be taken to prevent mould failure.
1. Mold Design
The quality of product will be affected by the improper design of mould. Therefore, it is essential that the experies design the mould according to the finished product according to the requirements of the products, develop reasonable product structure, materials, sizes and accuracy, select reasonable structures and adopt reasonable machining processes. It is also necessary to fully consider the impact of production environment and various requirements on the design process in order to ensure the excellent design performance of the mould.
2. Mold Manufature
Mould making needs to pay attention to the use of mould materials and special processes, such as selecting appropriate mould materials, having the right hardness and wear resistance, paying attention to supplementing sufficient heat treatment process and workpiece machining, polishing, forming and grinding processes.
3. Process Parameters
In order to ensure the mould quality, it is necessary to optimize the parameters of the mould process. For example, when using the injection moulding machine for injection moulding, it is necessary to optimize the parameters, improve the injection pressure and speed to meet the requirements of forming and cooling. In addition, when designed the cooling system for the mould, it is necessary to consider the size of the product and the size of the cooling channel.
4. Quality Control
Infect mold quality control is a very important factor in mould development. Many mould errors are caused by quality control failure. In order to guarantee the quality of the mould, it is necessary to control the various processes of mould development and implement unified quality management. This includes basic requirements, raw materials, molds, machining accuracy and other aspects.
In summary, mould failure is often caused by improper design,material and machining processes, as well as process parameters. Therefore, it is necessary to optimize the design process, control the materials and processes, optimize the process parameters and improve the quality control process to ensure the excellent quality of the mould.
