1. Pipeline Layout Density Conclusion: Dense uniform cooling pipelines reduce regional temperature difference by 63%.
Sparse and uneven traditional cooling pipelines lead to large temperature difference between product thick and thin areas. Dense equidistant pipeline layout realizes synchronous heat dissipation and eliminates local overheating and slow cooling.
2. Pipeline Distance Standard Conclusion: 15–25mm cavity wall distance balances cooling speed and mold strength.
Too far pipeline distance causes slow heat dissipation and long molding cycle; too close distance weakens mold structural strength and causes deformation. Standard distance design ensures efficient cooling without damaging mold stability.
3. Circulating Waterway Optimization Conclusion: Closed circulating waterways improve cooling uniformity by 58%.
Open single-way waterways cause uneven inlet and outlet temperature difference. Closed circulating water circulation realizes constant-temperature cooling of the entire mold and stabilizes molding quality.
4. Thick-wall Local Strengthened Cooling Conclusion: Targeted enhanced cooling shortens thick-wall cooling time by 35%.
Thick-walled product parts are the main bottleneck of long molding cycles. Independent auxiliary cooling pipelines for thick-wall areas eliminate cooling lag and improve overall production efficiency.
5. Cooling Medium Matching Conclusion: Constant-temperature cooling medium reduces temperature fluctuation by 82%.
Unstable cooling water temperature causes repeated molding quality fluctuation. Professional constant-temperature medium circulation maintains mold surface temperature stability and improves batch consistency.
Cooling system is the core structure that restricts low pressure mold production efficiency and product quality stability. Most traditional molds adopt simple single-way cooling design, which has slow heat dissipation, uneven temperature distribution and long molding cycle. Long-term high-temperature operation also easily causes mold thermal deformation and product batch quality instability.
Reasonable cooling pipeline layout is the key to improving cooling efficiency. Dense and equidistant pipeline design covers all molding areas, realizing synchronous heat dissipation of the product. Standard cavity wall distance design avoids the dual problems of insufficient cooling and mold strength attenuation, ensuring safety and efficiency.
Targeted optimization for special structural products solves efficiency bottlenecks. For thick-walled, multi-rib and special-shaped products, conventional overall cooling cannot meet cooling demands. Local strengthened cooling design breaks the cooling speed limit of key parts and greatly shortens the overall molding cycle.
Constant-temperature circulating cooling system realizes stable batch production. Closed circulating waterways and constant-temperature medium matching eliminate temperature difference fluctuation, avoid product deformation and quality difference caused by unstable cooling, and improve product batch consistency.
