Die Casting Mold Cooling Unit (Spot Cooler Mold Cooler)
- Each pipeline is equipped with a flow monitoring system and can output alarm signals to the die casting machine.
- The equipment has two different pressure outputs: spot cooling 0.6–1.2MPa; mold cooling 0.4–0.8MPa.
- The PID control module can automatically detect system pressure, so that when cooling water is shut off, the pump stops operating.

- Dual Pressure Output
The equipment provides two different pressure outputs: spot cooling 0.6–1.2MPa; mold cooling 0.4–0.8MPa.
- Rapid Pressurization and Constant Pressure Control
The equipment uses Xinyu’s self-developed PID control module, which controls the high-pressure pump through a frequency converter to achieve rapid pressurization. Once the set pressure is reached, it maintains constant pressure regardless of the number of pipelines opened, ensuring stable operation.
- Smart Water Shut-Off and Pump Stop Function
The PID control module can automatically detect system pressure, so when cooling water is shut off, the pump stops running, maximizing energy savings.
- Independent Control of Each Pipeline
Each group of pipelines can be controlled independently. Delay time and water supply duration can be set for each pipeline, enabling intermittent water supply.
- Reverse Air Blowing for Spot Cooling Pipelines
After all spot cooling pipelines have completed water supply, the system can be set to blow air, drying residual water in the pipelines to prevent scaling.
- Real-Time Display of Water Flow in Each Branch
Each pipeline is equipped with a flow monitoring system, allowing real-time display of water flow in the HMI. Alarm ranges can be set, and when flow is below the lower limit or above the upper limit, the unit triggers an alarm and can output alarm signals to the die casting machine.
- Flow Record Saving Function
Water supply records, flow curves, and mold process recipe information can be saved in the equipment.
The die casting mold cooling unit from Xinyu Intelligent Technology is a dual-pressure output device that integrates spot cooling and standard cooling functions. The dual pressure output and spot cooling functions precisely address local high-temperature areas of die casting molds (such as gates and cores). By rapidly cooling these areas, it reduces defects such as product scuffing and mold sticking.
For example, in automotive engine cylinder head die casting, this equipment can quantitatively manage the flow and pressure of each cooling circuit to ensure mold thermal balance and avoid casting deformation caused by uneven temperature. In addition, the mold pin break alarm function can promptly detect failures such as broken locating pins, preventing mold damage and production interruptions. It is particularly suitable for high-cycle die casting island production lines.
