The cooling of the cavity of the plastic injection mold is completed by the cooling water channel on the fixed template. The inside of the injection mold core is provided with cooling water holes, which are separated by a water barrier. The cooling water enters from the cooling water holes on the support plate, and rises to the upper part of the core along one side of the water barrier, and turns over The water barrier flows into the other side, and then flows back to the cooling water holes on the support plate. Then continue to cool the second core, and finally flow out of the injection mold from the cooling water hole on the support plate. Shorten the molding cycle of the part. Because there is no limitation of the cooling time of the runner system, the part can be ejected in time after it is solidified. Many thin-walled parts produced with hot runner molds can have a molding cycle of less than 5 seconds. Save plastic raw materials. Because there is no cold runner in the pure hot runner mold, there is no production cost. This is especially significant for applications where plastics are expensive. In fact, the major international hot runner manufacturers have all developed rapidly in the world when petroleum and plastic raw materials were expensive. Because hot runner technology is an effective way to reduce material costs.
The role of the plastic mold cooling system for plastic plate processing The design of the plastic injection mold cooling system directly affects the production efficiency of the injection mold and the quality of the plastic parts. The cooling effect of the cooling system determines the cooling time, and the cooling of the injection mold The time accounts for about 2/3 of the entire injection cycle. A complete cooling system can significantly reduce the cooling time, thereby improving the production efficiency of injection molds.
