YIXUN mold

Mold Structure Design:
Adopt a two-part mold (cavity + core), and embed core pins (to form mounting holes) and rib slides (to form surface reinforcing ribs) in the mold to ensure precise shaping of complex structures;
Design cooling channels (fitting the product’s curved surface) inside the mold to ensure uniform cooling during molding and avoid shrinkage deformation at the reinforcing ribs.
Mold Material Selection:
Use P20/S136 mold steel (wear-resistant and corrosion-resistant), with machining accuracy controlled within ±0.02mm—ensuring the thickness of reinforcing ribs and position error of mounting holes meet assembly requirements.
The material must first undergo drying treatment (dried at 80-90°C for 2-3 hours) to remove trace moisture in the material (preventing bubbles or silver streaks on the product surface after injection molding);
If the product requires a black appearance, pre-colored black raw materials are used directly (no post-painting needed, reducing costs and avoiding contamination).
Melting & Plasticizing: Heat the barrel to 180-220°C (adjusted based on plastic type) to melt the raw material into a uniform melt;
Injection & Mold Filling: Inject the melt into the mold cavity at a high pressure of 80-120MPa—ensuring the melt fully fills narrow structures (such as reinforcing ribs and mounting holes) to avoid "short shots" (unfilled partial structures);
Pressure Holding & Cooling: Maintain a holding pressure of 30-50MPa (to compensate for melt cooling shrinkage), and simultaneously pass cooling water through the mold’s cooling channels to cool the product to below 60°C for solidification (cooling time is about 20-30 seconds, adapting to uniform cooling of the curved structure);
Demolding & Part Removal: After the mold opens, eject the product via ejector pins (avoiding reinforcing ribs and mounting holes) to complete one molding cycle.
Deburring: Remove fine flash at the edges of mounting holes and reinforcing ribs (via automated equipment or manual trimming);
Dimensional Inspection: Use calipers and coordinate measuring machines (CMM) to spot-check the position accuracy of mounting holes and the thickness of reinforcing ribs, ensuring compatibility with other components;
Strength Testing: Conduct compressive/impact resistance tests on samples (verifying the structural support capability of reinforcing ribs).
