Cooling system cooling system is to control the mold temperature. Mold temperature has an impact on shaping the quality and efficiency of plastic molding, when the high mold temperature pp filter, molten plastic material flow better, help quickly filled cavity, to obtain high-quality products. But the temperature is too high plastic material curing time lengthened, while the top of the process is easily deformed. When the lower mold temperature, flow of plastic material will deteriorate pp, difficult to fill the mold cavity material, thereby resulting in increased stress, surface gloss molded article is poor, prone to crazing and weld marks and other defects. To understand the mold temperature is too high and too low to the product's pros and cons, the only reasonably be seen mold temperature in order to ensure product quality stability. Different plastic materials with different techniques, appearance requirements and structure of each product vary pp glue, in order to be able to produce products that meet the quality requirements of the products in the shortest period, the mold temperature is very important. The more stable mold temperature, the higher the quality of its size and appearance after injection products. The diameter of the cooling water is usually taken 6,8,10. Typically pp, mold, the greater the diameter of the waterway. If the mold is small, due to space constraints, the water can be designed to be smaller in diameter. For inlet, outlet must identify clearly need in the template lettering, as shown in Figure 2-32. Especially in how the group into seven outlet, the water pipes to prevent installation errors. The outer diameter of the cooling water from the edge of the cavity 10. The side wall should be greater than the interval between the water must be greater than 6 Mountain 3 refers to the diameter of water, water from the side wall should be greater than 410,111 thimble, in order to ensure adequate strength to prevent breaking through waterways . Ring to be fixed in a given template move 7, to be processed on the template of the mounting structure before loading 0-ring. Interval size ring and waterways shown in Figure 2-35 shows that the interval must be greater than one purpose, to ensure adequate strength. pp synthetic paper, Mission pp, Gary Paffett trade provided by the Shenzhen Municipal Trade Co., Ltd.
