Low pressure casting pieces

Solutions for low pressure casting parts are designed to solve various problems that may be encountered in the low pressure casting process and improve casting quality and production efficiency.

Ⅰ. Low pressure casting solutions overview

Low pressure casting is a special casting method between gravity casting and pressure casting, which uses gas pressure to hydraulic metal into the mold, and makes the casting crystallize under a certain pressure. The method has the advantages of high casting quality, complex thin wall casting and high metal utilization rate. However, in the actual production process, low-pressure casting parts may also face a series of problems, such as ejecting deformation, casting defects, etc. Therefore, a range of solutions is required to optimize the low pressure casting process.

Ⅱ. Low pressure casting parts common problems and solutions

1. Ejection deformation problem description: After the casting is opened, part of the structure can not fall off smoothly, resulting in deformation and scrap of the casting.

Solution: Using the principle of "guide column guide sleeve", the force is redistributed, and the convex top rod or casting convex is made to balance the unbalanced wrapping force. Optimize the mold design to ensure a good connection between the mold and the lifting mechanism to avoid poor ejecting caused by oil pressure, stroke state and other problems.

2. Casting defect problem description: the surface of the casting has defects such as sticky sand, flow hanging, insufficient pouring or choking.

Solution: Before using the mold, clean the paint on the surface of the mold before production. According to the different casting materials, choose the appropriate paint, and use special spraying equipment for uniform spraying. Optimize the casting process, ensure that the production equipment meets the low pressure mold casting needs, and carry out special training for the production personnel.

3.Dynamic instability problem description: The power output of the traditional power source is unstable during the low-pressure die casting process, resulting in poor flow of metal liquid in the mold and unstable casting quality.

Solution: Introduce servo motor power system to achieve accurate and stable control of power output. The use of hydraulic hybrid power system, combined with the powerful power of hydraulic and electric precision control, to improve the strength and accuracy of power supply. The intelligent power control system is introduced to monitor various parameters in the die casting process in real time, and adjust the power supply according to the data to ensure that the die casting process is carried out in the best dynamic state.

Ⅲ. Supporting measures

1. Maintenance of power equipment Regular maintenance of servo motor, hydraulic system and other power equipment to ensure that the equipment is in good condition.

Check line aging, bearing wear, oil leakage and other problems, and timely treatment.

2. Operator training Professional training for operators, so that they are familiar with the new power system operation methods and precautions.

Upgrade the skill level of operators to ensure they can take full advantage of the performance benefits of the new powertrain.

IV. Summary

Low pressure casting solutions need to consider a number of aspects, including ejection deformation, casting defects, dynamic instability and other issues. By optimizing mold design, selecting suitable coating and spraying equipment, introducing new power systems, and strengthening equipment maintenance and operator training, the quality and production efficiency of low-pressure casting parts can be effectively improved. At the same time, these solutions also provide enterprises with the motivation and support for sustainable development.
