Cold Chamber Die Casting Machine Aluminum New Energy Vehicle 3-in-1 Power Module Shell Machine

Developed for producing integrated liquid-cooled aluminum EV high voltage power distribution housings and OBC enclosures, this 400-ton cold chamber die casting machine realizes one-piece forming of complex internal cooling flow channels for 3-in-1 on-board power units. High-power new energy vehicle power modules generate significant heat during operation; traditional assembled cooling channel structures carry leakage risks and high thermal resistance. This 400T equipment forms intricate liquid cooling channels in a single die casting step, eliminating assembly seams, reducing thermal resistance and greatly improving heat dissipation efficiency and operational reliability of on-board power systems.

Constructed with a precision reinforced frame system matched with high-strength tie bars, precision positioning steel pins and extra-thick machine platens, the machine delivers ultra-high mold positioning accuracy at 400 tons of clamping force. This stable, rigid structure ensures accurate alignment of slender cooling channel core pins during high-pressure injection, preventing core pin deflection and channel blockage. For liquid-cooled new energy vehicle power module shells, it guarantees consistent flow channel cross-section dimensions, smooth inner walls and uniform wall thickness, achieving stable coolant flow and even heat dissipation across the entire 3-in-1 power unit housing.

Adopting a German PLC intelligent closed-loop control system and high-definition color human-machine interface, the machine supports multi-stage variable-speed injection parameter customization for complex flow channel structures. Optimized slow exhaust followed by high-speed uniform filling completely eliminates cold shuts and blockages inside narrow cooling channels, ensuring unobstructed coolant flow. The one-click parameter storage function enables rapid switching between different liquid-cooled housing specifications, while maintaining consistent forming quality. The simplified electrical circuit runs stably in high-temperature environments, and the real-time fault display function ensures rapid fault diagnosis and efficient production recovery.

The dual-proportional hydraulic system delivers smooth, responsive multi-stage injection and gentle low-pressure mold clamping, protecting fragile cooling channel core inserts from bending or breaking while ensuring complete filling of complex flow structures. Premium European and Japanese hydraulic oil seals ensure long-term leak-free operation with stable pressure output, maintaining consistent injection performance for precision liquid-cooled parts. The efficient hydraulic die height adjustment system shortens debugging and replacement cycles for different liquid-cooled OBC enclosure molds, improving flexible production efficiency. The automatic pressure relief energy-saving system intelligently reduces energy consumption during operation.

The precision uniform-stress clamping mechanism ensures balanced mold force and stable core positioning, avoiding uneven wall thickness and flow channel deformation. The high-flow valve and precision piston accumulator injection system provides steady, powerful injection force that fully fills intricate internal cooling channels without defects. Matched with an efficient oil cooling system, the machine maintains stable hydraulic performance during long production runs, with a service life of 15 to 20 years. An optional mold sweeping robotic arm is available to further improve automation level.
