Generally speaking, the lead time of mold-scale enterprises is about 18 days, mold manufacturing is about 15 days, and electrode manufacturing and electric discharge processing is about 11 days. It can be seen that electrode manufacturing and electric discharge machining account for 62% of the mold delivery cycle, and strengthening the management of the electrode processing manufacturing process and improving the level of automation is the key to shortening the mold manufacturing cycle and improving the technical level of mold manufacturing. Information management of the electrode life cycle is very important, and it is also the key technical content of mold Internet of Things technology.

The current situation of small precision mold manufacturing workshop is: the number of tools and electrodes is large, the replacement is frequent, and the equipment operation rate is low; Large number of devices, complex systems, and difficult networking; With an average of 2 workers per equipment, the working experience and working status of workers are particularly important, and the quality of molds completely depends on personnel and experience management, and it is difficult to achieve high standards and high quality.

The application process of mold Internet of Things in small precision mold manufacturing workshop is as follows: automatic transmission of processing parameters for tool electrode labels, automatic positioning of tool points, automatic tool change for batch processing, CNC automatic machining start, automatic import of EDM machining offset, unattended machining of multiple electrodes, automatic execution of EDM machining requirements, CMM multi-point modeling detection, automatic comparison of quality data, automatic extraction of offset data. A large amount of data is concentrated in the background server software and hardware integration system to achieve barrier-free transmission.

The use of mold Internet of Things technology in small precision mold manufacturing workshops has produced good results: the equipment operation rate has increased by 10% and 20%, the personnel has been reduced by 50%, the mold development and manufacturing cycle has been shortened by about 3 days, and the mold manufacturing cost has been reduced by about 20%.

The characteristics and status quo of large-scale precision mold manufacturing are: the need for transportation tool scheduling, many types of special equipment, and difficult system integration; The quality control of each process needs to be monitored online; The process control is difficult, and the mold delivery cycle is difficult to guarantee; There are many processes, the working hours are not accurate, and the cost quotation is difficult to control.

(1) CNC machining. A variety of equipment data is automatically assigned through tags and acquisition equipment, batch equipment tools are automatically assigned, and NC programs are automatically diverted and recognized.

(2) Flexible manufacturing system. CNC and EDM and CMM as well as warehouses and distribution intelligent integration, based on the flexibility of the Internet of Things to achieve the overall flexible platform.

(3) Distribution system. Self-distribution of tools, electrodes and workpieces, wireless laser rail making multi-point distribution, palletizing truck material transportation. The use of mold IoT technology in large-scale precision mold workshops has also produced good results: the overall production efficiency of the workshop has increased by 20%, and the order delivery cycle has been shortened by 30%.
