Introduction to the use of high-gloss mold temperature machine
The hot nozzle of the high-gloss mold must be equipped with a sealing needle, and each hot nozzle must have an independent air channel, so that the injection time and the amount of glue of each hot nozzle can be controlled separately through the solenoid valve and the time relay, which is used for the injection molding machine. Good necessary preparations.
The high-gloss mold temperature machine uses this machine to generate high-temperature steam (the maximum temperature is 200 degrees, no boiler is required), and the temperature is quickly supplied to the mold, so that the mold temperature rises instantaneously, and the fluidity of the resin in the mold cavity is guaranteed. Using high-temperature steam water, make a constant heating channel on the mold (similar to the cooling channel of an ordinary mold). When the injection molding machine blows in high-temperature steam water before opening the mold, first raise the mold temperature to a set value, and then start to inject plastic into the mold cavity, and the injection pressure is maintained while injecting the machine's refrigerated stable frozen water to cool the mold instantaneously Come down (minimum water temperature is 10 degrees). Through instant cooling, the cooling time of the product is greatly shortened, which is in line with the requirements of modern injection molding technology. After the mold temperature drops to a set value quickly, the mold is opened and the entire injection molding process is completed.
The purpose of the high-gloss injection molding performed by the high-gloss mold temperature machine is to make the mold temperature quickly heat up to the temperature of 110130 before injecting the glue. The temperature is also determined by the thermal conductivity of the plastic material and the mold. Cooling is only an auxiliary product and speed up the product. Molding, but effectively shorten the molding time. The rapid cooling and rapid heating temperature control of the high-gloss mold temperature machine plays a role in uniform plastic fluidity during the injection molding process and greatly improves the yield.
