With the continuous development of automobile industry and other industries, die casting purchasers have increasingly strict requirements for castings. Therefore, die casting enterprises will put forward higher requirements for die casting machines today and in the future.
From the perspective of yield and efficiency of die casting production, this paper briefly introduces several die casting machines.
High yield in die casting production
The key to the yield of die castings lies in the injection performance and the stability of die casting production.
1. In terms of injection performance
The high performance of air compression speed can reach 8-10m / s, and the low-speed injection speed can be adjusted from tens of millimeters per second to hundreds of millimeters per second. It has multi-stage injection control. Generally, it is required to reach 10 sections, making the process setting more flexible
The speed reduction function can prevent flash and ensure the service life of the machine and die. The pressure building time can be shortened to more than ten milliseconds, or even 10ms.
2. From the stability of die casting production
With the rapid growth of computer operation speed and the continuous improvement of the performance of corresponding hydraulic system, hydraulic components and electronic components, real-time control technology has become more and more perfect. Improve the furnace and supporting equipment, such as "suction casting" soup taking and closed holding furnace, smaller accumulator pressure drop, independent control of injection and mold closing, which can better ensure the stability of mold closing and injection, make the distribution of mold locking force more uniform, and reduce formwork deformation and product flash low failure rate.
3. Efficiency of die casting production
Die casting pre filling technology, such as hot chamber machine alloy liquid can stay in the nozzle body (material pipe), rapid die change technology, shorten the shutdown time, optimize the oil circuit and motor, and increase the pressure and speed, so as to shorten the production beat. Automatic peripheral support, no shift change, 24-hour production.
