Common Cooling System Designs for Injection Molds
The design of the cooling system in injection molds is a critical step in ensuring product quality and improving production efficiency. The cooling system must be optimized based on the mold structure, product characteristics, and production requirements.
1. Linear Cooling System
Characteristics:
The cooling channels are arranged in a straight-line configuration, suitable for simple mold structures and products with regular shapes.
Advantages:
Simple design, easy to manufacture.
Low flow resistance for the cooling liquid, with stable heat transfer performance.
2. Annular Cooling System
Characteristics:
Cooling channels are arranged around the core of the mold, ideal for cylindrical or symmetrical products.
Advantages:
Provides better uniformity in cooling.
Quickly transfers heat from the core to the cooling channels.
3. Spiral Cooling System
Characteristics:
Cooling channels are arranged in a spiral pattern around the mold cavity, suitable for products with uniform wall thickness.
Advantages:
High cooling efficiency with extensive coverage.
Uniform heat transfer, promoting consistent product quality.
4. Parallel Cooling System
Characteristics:
Cooling liquid flows through multiple parallel channels simultaneously, ideal for cooling large-sized products.
Advantages:
Rapid cooling speed with high heat exchange efficiency.
Avoids prolonged cooling times associated with single-channel systems.
