1、 Working principle:
The working principle of different types of fully automatic ceramic core machines varies. Taking the equipment for manufacturing ceramic cores by hot pressing injection method as an example, it is controlled by PLC and touch screen program, and has fully automatic processes such as ceramic core slurry preparation, vacuum pumping, high-pressure mold closing, and slurry injection. Firstly, ceramic raw materials are mixed with binders to form a slurry, which is then placed in a slurry tank. Under pressure, the slurry is injected into the mold cavity, and through heating, cooling, and other processes, the ceramic core is solidified and formed.
2、 Structural composition
1. Power system: usually includes a hydraulic system and a pneumatic system. The hydraulic system provides clamping force, injection pressure, etc., such as a two-stage vane pump providing a high flow and high pressure interconversion oil supply system, and the pneumatic system is used for some auxiliary actions, such as partial actions of the sand injection and blowing exchange device.
2. Mold system: including upper and lower molds, with heating and cooling devices on the workbench that can control the temperature of the upper and lower molds separately to meet different process requirements.
3. Control system: It consists of a programmable controller, a touch screen human-machine interface, and electrical standard components. The operation of the core making machine is controlled by sensors such as travel switches and actuators such as air valves and hydraulic valves installed on the equipment. The operator can set operating parameters through the human-machine interface.
4. Slurry conveying system: including slurry tank, injection device, etc. The slurry tank is used to store the slurry, and the injection device precisely injects the slurry into the mold under pressure.
5. Auxiliary system: such as the central lubrication system, which consists of a lubricating oil pump, distributor, cycle switch, pipeline, etc., and can automatically distribute lubricating medium to various moving objects in a centralized manner; There is also an exhaust gas recovery system used to recover and treat the waste gas during the core making process.
3、 Equipment features
1. High degree of automation: By adopting electrical control automation, the automatic core making process can be achieved, reducing manual intervention, improving production efficiency and product quality stability.
2. Precise control: The control center is controlled by PLC and touch screen program, which can accurately control parameters such as mold clamping force, injection pressure, temperature, etc., to meet the production process requirements of different ceramic cores.
3. Stable performance: The hydraulic system is stable, using imported hydraulic oil pumps, valve groups, electrical components, etc. to ensure long-term stable operation of the equipment.
