Factors affecting the product cooling rate are: plastics design. Mainly plastic wall thickness. Product thickness, the longer cooling time. In general, the cooling time is about proportional to the square of plastic thickness, or the maximum flow channel power is proportional to the diameter of 1.6. That doubles the thickness of plastic products, Cooldown increased 4-fold. Mold materials and cooling. Mold materials, including a large mold core, cavity material and mold material impact on the cooling rate. The higher thermal conductivity of mold material, the better the heat transfer out of the effect from the plastic unit of time, the cooling time is shorter. Cooling water pipe configuration. Cooling water closer to the mold cavity, larger diameter 350 tons of plastic plants, the greater the number, the better the cooling effect, the shorter cooling time. Coolant flow. Cooling water flow greater (typically to achieve turbulence better), thermal convection cooling water to remove heat effect is better. Nature of coolant. Viscosity and thermal conductivity of the coolant also affect the heat transfer effect of the mold. The lower the cooling fluid viscosity, the higher the thermal conductivity, the lower the temperature, the better the cooling effect. Plastic selection. Plastic means plastic to measure the direction of the heat from the hot cold places conduction velocity. The higher thermal conductivity of plastics, the better is the heat conduction effect, or plastic is lower than the heat, the temperature is easy to change, and therefore easy dissipation of heat, thermal conductivity better results, the required cooling time is shorter. Machining parameters. Material temperature, the higher the mold temperature, the lower the ejection temperature, the longer the cooling time. Thermosetting plastic during the forming process is heated under pressure to shift in plasticity viscous flow state, along with increased mobility cavity filling large plastic machine factory, plastic plants at the same time the condensation reaction, the crosslinking density is increasing, Liquidity rapid decline gradually solidified melt material. Mold design for curing speed, maintaining flow state short of material should be taken to facilitate the loading, unloading and reasonable choice of insert molding conditions and other operations in order to avoid premature or less hard by the hardening, resulting in plastic molding defects. Curing speed is generally available from the holding time to analyze it with the plastic variety, wall thickness, the shape of plastic parts, mold temperature related. But also by other factors, especially in the warm-up state of proper warm-up should be maintained so that the plastic can play at maximum flow conditions, to maximize its curing speed, preheat temperature is generally good quality plastic processing plants, long time (within the allowable range) accelerate the curing speed, especially the pre-pre-heated by the high frequency spindles blanks are hardened significantly faster. In addition, high temperature molding, pressing for a long time also increases the curing speed. Thus, the curing speed can be adjusted or warm forming conditions properly controlled. The method for forming hardening rate also requires, for example, injection molding requirements in plastics extrusion should be filled when the chemical reaction is slow, slow hardening, should maintain flow state for a long time, but when the cavity is filled after the high temperature, high pressure Under should quickly hardened.
