The ever-changing tire market environment has made tire molds flexible and changeable, and the number of tire molds has increased dramatically. The functional attributes of the mold itself determine that it cannot have the slightest error. In addition, the mold is closely related to product development, sales planning, production mold change, product quality, product traceability, procurement and external repair, and so on. Therefore, it is very important to explore the standardized management mode of molds. important.
The mold information management system is a set of multi-functional operation platform with collaborative participation of multiple departments. It has established a collection of product technical parameters, mold ledger, mold location ledger, vulcanizing press ledger, mold equipment ledger and other data ledger, and It has functions such as machine status monitoring, mold warehousing management, planned mold change management, allocation management, cleaning and maintenance management, purchase acceptance management, mold change first inspection, product quality feedback, data statistics query and other functions. It has passed the EAS system and the tire number system. , OA system interface, implement all-round management of all mold business, in order to realize real-time data collection, release, sharing, business centralized management and monitoring, resource optimization configuration, through the system platform to standardize the business process and management methods of each department, use The information carrier solidifies the lean management model to improve work efficiency, plug management loopholes, improve the stability of product quality, and ultimately enhance the executive power of corporate management.
The following briefly introduces its main functional modules:
(1) Mold ledger and location management
The mold ledger is the core of all mold business operations. The system is established according to the mold composition: mold set ledger, side plate ledger, flower block ledger, movable block ledger, steel ring ledger, chuck ledger, spare parts desk Accounts for 7 types of ledgers, and establishes warehouse areas and locations according to their storage areas and storage methods, implements location management for 7 types of mold parts, and uses wireless handheld terminals for in and out operations for each use and storage. The entire on-site mold 5·S setting work is orderly, coupled with the extensive sharing of mold accounts, greatly improving the quality and efficiency of related work.
(2) Mold combination and data association
Establish the corresponding relationship according to the actual assembly and matching attributes of each mold component, with the EAN product code and side plate as the core, establish the data association relationship between EAN and side plate, side plate and machine, side plate and flower block, mold sleeve and other parts For example, if you want to change the mold of 11.00R20 SAM01 with the EAN of 8165 in the 50# machine, you only need to enter the machine numbers 50# and 8165, the system will automatically associate the side plate, select the side plate and then automatically associate other mold parts, and change the mold for production. It provides great convenience to ensure the accurate matching of mold components, which can effectively prevent assembly errors from occurring.
(3) Production planning and mold change management
With the mold ledger and data association, and in accordance with the actual production mold change business process, the system has established a rigorous electronic approval process, starting with the production plan, mold change plan, mold change task assignment, preparation of mold change construction tables, and implementation of the change. From the mold, to the mold change and acceptance, the entire system process is followed, and the mold change process is interfaced with the tire number system to further realize product traceability.
(4) Machine monitoring and status time statistics
The machine is divided into 10 states such as vulcanization, shutdown, material waiting, mold change, and maintenance. The barcodes are coded separately, and the state of the machine is obtained by scanning the status barcode with a wireless handheld terminal to realize machine monitoring. The vulcanizer scans the machine number bar code and status bar code, selects the reason for shutdown or maintenance and then confirms to change the machine status. The monitoring screen and WEB page can monitor the machine status in real time and display the cause of the shutdown. The system also counts the frequency of status and causes, downtime, and average time, which will provide scientific and accurate decision-making basis for production management and equipment management.
(5) Mould allocation management
In order to make full use of mold resources, the company has a situation of mutual transfer of molds among the three factories of Hualun, Fengli and Baoli, and the transfer of molds involves the comprehensive planning department, the mold management departments of both parties, the financial departments of both parties, and the factory’s security. Therefore, the system has established a mold allocation management module involving the mold demander, mold provider, and comprehensive planning department. Other departments can monitor and inquire about the allocation process.
(6) Product quality feedback
The mold information system has established two quality feedback modules for mold change first inspection and product inspection. It provides timely feedback and treatment of product quality problems caused by molds, and records which machine and mold produced a certain product defect. For the information of who assembled the mold, the system will also perform statistics on the recorded information to provide a solution for accurately grasping the source of the problem, and ultimately improve the overall quality of the product.
(7) Plan mold washing, plan repair, plan maintenance
The mold ledger comes with three status attributes: “Whether to be washed”, “Whether to be repaired”, and “Whether to be maintained”. According to the mold’s waiting to be washed, to be repaired, and to be maintained, the production arrangement is planned in a planned way, and the planned cleaning, repair and maintenance of the mold is realized in a true sense.
(8) Outsourcing maintenance and procurement acceptance management
Due to the large number of external mold repairs and purchases of new molds, whether molds are shipped out, whether they are repaired, whether they are purchased back to the factory, whether they are accepted, are closely related to production and mold changes, so the mold information system has established outbound maintenance and procurement acceptance The management module, the return status and acceptance status of the mold can be published and shared on the Internet in real time, which is convenient for all relevant departments to make production arrangements.
