Hydraulic pumps play a vital role in die casting machines, which are used to produce metal parts with complex shapes and precision. Following are some key applications of hydraulic pumps in die casting machines: 1. Injection system: The hydraulic pump is used to power the injection system in the die casting machine. The injection system consists of hydraulic cylinders and plungers, which are responsible for injecting molten metal into the mold cavity. The hydraulic pump generates the necessary high-pressure hydraulic oil to drive the hydraulic cylinder, thus precisely controlling the injection speed and pressure. 2. Clamping system: Die casting machines require a strong clamping system to securely hold the mold together during the casting process. A hydraulic pump powers the clamping system, which usually consists of a hydraulic cylinder and a toggle mechanism. A hydraulic pump applies the force required to hold the mold in place with enough pressure to withstand the high forces and pressures involved in the casting process. 3. Ejection system: After the metal is solidified in the cavity, the casting needs to be ejected from the mold. A hydraulic pump is used to drive the ejection system, which may include hydraulic cylinders or ejector rods. A hydraulic pump provides the force needed to eject the casting from the mold, ensuring smooth and efficient part removal. 4. Cooling system: The die casting machine is equipped with a cooling system to control the temperature of the mold and regulate the solidification process of the molten metal. A hydraulic pump drives a cooling fluid, such as water or oil, to circulate through cooling channels within the mold. This helps dissipate the heat generated during casting, maintaining optimum mold temperatures and ensuring consistent part quality. 90-L-130-KA-5-NN-80-L-3-C8-F-03-GBA-42-42-24 90L130KA5NN80L3C8F03GBA424224 90-L-130-KA-5-NN-80-L-3-C8-H-03-GBA-14-14-24 90L130KA5NN80L3C8H03GBA141424 90L130-KA-5-NN-80-L-3-C8-H-03-GBA-23-23-24 90L130KA5NN80L3C8H03GBA232324 90-L-130-KA-5-NN-80-L-3-C8-H-03-GBA-23-23-24 90L130KA5NN80L3C8H03GBA232324 90L130-KA-5-NN-80-L-3-C8-H-03-GBA-35-35-24 90L130KA5NN80L3C8H03GBA353524 90-L-130-KA-5-NN-80-L-3-C8-H-03-GBA-35-35-24 90L130KA5NN80L3C8H03GBA353524 90L130-KA-5-NN-80-L-3-C8-H-03-GBA-38-38-24 90L130KA5NN80L3C8H03GBA383824 90-L-130-KA-5-NN-80-L-3-C8-H-03-GBA-38-38-24 90L130KA5NN80L3C8H03GBA383824 90L130-KA-5-NN-80-L-3-C8-H-03-GBA-42-14-30 90L130KA5NN80L3C8H03GBA421430 90-L-130-KA-5-NN-80-L-3-C8-H-03-GBA-42-14-30 90L130KA5NN80L3C8H03GBA421430 5. Lubrication system: In order to minimize the friction and wear between moving parts, the die casting machine needs a lubrication system. Hydraulic pumps deliver lubricant to various components such as slides, rails and other moving parts to reduce friction and improve operating efficiency. Proper lubrication is essential for smooth motion and long component life. 6. Auxiliary functions: Hydraulic pumps can also power various auxiliary functions in the die casting machine, such as the operation of safety systems, core puller slides, hydraulic core pullers, or other auxiliary operations involved in the die casting process. These auxiliary functions support the overall operation of the machine and contribute to its productivity and versatility. 7. Pressure control: The hydraulic pump provides the necessary pressure control during the die-casting process. They can adjust injection pressure, clamping force and ejection force to meet the specific requirements of different casting materials, part geometries and production parameters. Precise pressure control ensures consistent part quality, minimizes defects and optimizes the entire casting process. 8. Energy Efficiency: Modern die casting machines strive to improve energy efficiency in order to reduce operating costs and environmental impact. Energy-efficient operation with state-of-the-art hydraulic pumps such as variable displacement pumps or servo-driven pumps. These pumps adjust flow and pressure according to actual demand, reducing energy consumption during idle or low load conditions. 9. Speed and Responsiveness: Hydraulic pumps with fast response times and high-speed capabilities are critical for efficient and productive die casting operations. Fast injection speeds and fast clamping and ejection motions help reduce cycle times and increase productivity. Hydraulic systems including pumps, valves and actuators must be designed and optimized to provide the required speed and responsiveness. 10. System integration: The hydraulic pump in the die casting machine is integrated into a larger hydraulic system, which includes valves, actuators, sensors and control units. The pump works in conjunction with other components to ensure the coordinated and synchronized operation of various machine functions. Effective system integration requires careful design, hydraulic circuit optimization and proper calibration for efficient and reliable performance. 11. Maintenance and troubleshooting: In order to ensure its best performance and service life, the hydraulic pump in the die-casting machine must be regularly maintained and monitored. This includes regular inspections, lubrication, filter changes and fluid analysis to detect potential problems and prevent breakdowns. Additionally, a comprehensive troubleshooting program should be in place to quickly identify and resolve any pump-related issues, minimizing downtime and production interruptions. 90L130-KA-5-NN-80-L-3-F1-F-03-GBA-42-42-24 90L130KA5NN80L3F1F03GBA424224 90-L-130-KA-5-NN-80-L-3-F1-F-03-GBA-42-42-24 90L130KA5NN80L3F1F03GBA424224 90L130-KA-5-NN-80-L-3-F1-H-03-GBA-26-26-24 90L130KA5NN80L3F1H03GBA262624 90-L-130-KA-5-NN-80-L-3-F1-H-03-GBA-26-26-24 90L130KA5NN80L3F1H03GBA262624 90L130-KA-5-NN-80-L-4-C8-F-05-GBA-30-30-24 90L130KA5NN80L4C8F05GBA303024 90-L-130-KA-5-NN-80-L-4-C8-F-05-GBA-30-30-24 90L130KA5NN80L4C8F05GBA303024 90L130-KA-5-NN-80-L-4-C8-H-03-GBA-42-42-24 90L130KA5NN80L4C8H03GBA424224 90-L-130-KA-5-NN-80-L-4-C8-H-03-GBA-42-42-24 90L130KA5NN80L4C8H03GBA424224 90-L-130-KA-5-NN-80-L-4-F1-F-00-GBA-20-20-24 90L130KA5NN80L4F1F00GBA202024 90L130-KA-5-NN-80-L-4-F1-H-03-GBA-14-35-24 90L130KA5NN80L4F1H03GBA143524 12.
