Description

Quick cooling device for injection mold

Technical Field

The utility model relates to a quick cooling device for injection mold.

Background

Today's plastic products will no longer exist if careful temperature control of the process heating and cooling is not applied. Injection molding requires that some plastics be heated up to 287 ℃. Due to these high temperatures, proper cooling may be one of the most important steps in the overall plastic manufacturing process; for a single plastic component, the plastic cooling and recovery phase may take up to about 80% of the total manufacturing time. Optimizing this cooling stage prevents shrinkage and other plastic defects, reduces production time, produces stronger finished products, reduces costs, and protects valuable injection molding equipment. There are two main ways to remove heat around a plastic injection mold: air-cooled water coolers and water-cooled water coolers. Air-cooled refrigeration uses forced air to transfer the waste material from the injection molding apparatus to the surrounding air. Air cooled chillers may be an effective cooling method for small volume plastic manufacturing, but are often inadequate when produced in large volumes. Air is a less efficient heat transfer material than fluid and requires a long time to properly cool the injection mold before the part is ejected. Air-cooled chillers are also less energy efficient because you need to dissipate heat for more space, rather than direct cooling power to the desired location. A water cooled plastic chiller runs a cooling fluid (typically a mixture of ethylene glycol and water) directly around the injection mold. The waste heat is transferred to the cooling fluid and then continuously returned to the chiller unit where the cycle begins again. Thermal engineers typically specify precise heating and cooling specifications for injection molding machines. These temperature control objectives depend on many factors, including the type of plastic used, the thickness and size of the part, and the design of the mold itself. The use of plastic water coolers with fluids may help manufacturers to more accurately achieve these temperature targets than air water coolers. However, the water consumption of the cooling device of the existing injection mold is still large, and the waste of the main water is more; in addition, the existing cooling device can only cool the injection mold with one shape and size, and the applicability is not high.
