At the beginning of 2020, Aode responded to customer needs and developed an integrated die-casting intelligent temperature control system for large-scale automobile structural parts to help the lightweight development of new energy automobile enterprises. So far, several sets of services have been provided to well-known new energy automobile enterprises. Let me share with you Principles and solutions of integrated die-casting intelligent temperature control system for large automobile structural parts.
With zero emission and light weight becoming the development trend of the global automobile industry, it is also an important way to save energy and reduce emissions. At the same time, China's new energy automobile market is developing rapidly, and the demand for mold temperature balance of large-scale automobile die-casting structural parts is clear. Automobile lightweight is mainly divided into material lightweight and structural lightweight. Considering factors such as cost and production difficulty, aluminum alloy and structural parts die-casting are the preferred materials and optimal processes. When automobile structural parts are converted to large light alloy thin-walled castings, on the one hand, it can effectively achieve light weight; on the other hand, because the structure is highly integrated and integrally formed, the forming and connection links are reduced, the process is simplified, and the cost is reduced.
The temperature control in the integrated die-casting process of large automobile structural parts is the key link. The temperature control includes the temperature balance control of the mold, the pressure chamber and the punch, the split cone and the sprue sleeve, etc. The mold temperature control system is continuously working through the mold temperature unit. Control the temperature of the movable and fixed mold, mold meat and mold base, use the atmospheric cooling device to continuously work to control the temperature of the pressure chamber, the punch splitter cone and the sprue sleeve, and use the high pressure mold cooler to intermittently work to control the temperature of the mold core and module. The fine core point cooler intermittently works to control the temperature of the core pin and the small insert.
Among them, the mold temperature machine is used to adjust the balance of the mold temperature, which can increase or decrease the temperature. The mold temperature machine uses a heat-conducting medium with high thermal conductivity to increase the temperature in the mold or send away excess heat in a short period of time. After setting the thermal equilibrium temperature, the temperature can be automatically controlled within a very small error and the fixed value can be maintained. Using the mold temperature machine to adjust the balance temperature of the mold can preheat the production temperature of the mold, optimize the cycle time, better promote product shaping, and reduce the majority of defective products when starting up.
The trend of automobile structural parts will be integrated: integrated and combined
Large-scale automobile die-casting structural parts put forward higher requirements for mold temperature balance, and mold temperature control has become a rigid demand. Based on the close relationship with the automobile/communication and die-casting markets in the past two decades, Aode is based on the integration of large-scale automobile die-casting structural parts. To meet the temperature control requirements, we have developed and designed a systematic solution, and launched a series of products (200℃ water temperature controller, 320℃ oil temperature controller, hot and cold temperature control station, and more Channel mold cooler, multi-channel point cooler).
We believe that the process of ultra-large automobile die-casting structural parts is long and thin, so the mold temperature is required to accurately control the temperature of different mold areas according to different flow patterns during the long process. Therefore, the width of mold temperature control is known and Unknown demand, therefore, on this basis, Aode, drawing on previous design and application experience, designed a wide temperature range from 20°C to 320°C to provide a stable and controllable temperature source output for the mold temperature balance, and at the same time a large temperature The output can not only control the temperature balance of the mold, but also extend to control the temperature of the pressure chamber, punch, split cone, sprue bushing, etc., thus leaving enough room for the on-site die-casting product technologists.
Intelligent integrated control mold temperature central integrated control management is an inevitable trend in the production and management of large and super large die casting machines. Now the number of mold temperature control equipment required for the application of 5000T/6000T/7200T/8000/9000T in the market is huge , The temperature output point required to control the temperature is several times of the actual machine quantity. A single control will increase the workload of process debugging, which is not conducive to rapid production. Therefore, centralized control of all temperature control equipment is required. The control system includes the setting monitoring of temperature, flow, pressure and other settings and data collection of a single unit to achieve digitalization. At the same time, the control system can facilitate the addition or reduction of oil, water, point and other temperature control equipment according to different casting configuration requirements, and quickly optimize the adjustment of temperature/flow/pressure data in each mold temperature zone during production.
