Temperaturen på plastform har stor indflydelse på kvaliteten af produktstøbning, som er en af de tre vigtigste procesbetingelser ved sprøjtestøbning. Til præcisionssprøjtestøbning, der er ikke kun problemet med høj og lav temperatur, men også problemet med temperaturstyringsnøjagtighed. Naturligvis, i gang med præcisionssprøjtestøbning, hvis temperaturkontrollen ikke er nøjagtig, the fluidity of plastic melt and the molding performance and shrinkage of the product will not be stable, so the accuracy of the finished product can not be guaranteed. Generelt, temperaturkontrolboksen, varmering og andre systemkombinationsmetoder bruges til at styre formtemperaturen.
1. Der er flere måder at opvarme eller afkøle formen af plastikform. Steam, varm olie cirkulation, hot water circulation and resistance can be used to heat and raise the temperature of the mold. Cooling water or air can be used to cool the mold. Resistance heating and cooling water circulation cooling are widely used in the temperature regulation of injection mold. When heating the mould by resistance, the flat part is heated by resistance wire, the cylinder part is heated by electric heating coil, and the mould body is heated by electric heating rod. The cooling part of the mold needs to be cooled by arranging the circulating water pipe. The resistance heating and cooling water circulation work alternately according to the specific temperature conditions of the die, so that the die temperature is controlled within the temperature range required by the process.
2. Forholdsregler for kontrol af formens temperatur:
(1) After heating, the temperature of each part of the molding mold should be uniform to ensure that the molten material has better filling quality, so that the molding quality of the injection products can be guaranteed and the qualified rate of the injection products can be improved.
(2) The specific process temperature adjustment should be determined by the viscosity of the melt. When the melt with higher viscosity is injected into the mold, den specifikke temperatur af formen skal justeres lidt højere; The temperature of the mold can be reduced by filling with lower viscosity melt. In preparation for injection production, the mold specific temperature is within the range of process requirements. In order to ensure the uniform temperature of the mold, the mold with the required temperature should be kept constant for a period of time.
(3) During injection molding of large plastic products, due to the large amount of molten material and the small flow path of molten material, the large mold should be heated and moisturized at the flow path of molten material, so as to prevent the molten material from cooling when flowing due to the long flow path of molten material and increase the viscosity of molten material, so as to slow down the flow of molten material, affect the filling quality of molten material injection mold, and cause the molten material to cool and solidify in advance, The injection work of the injection molding machine can not be carried out.
(4) In order to reduce the temperature drop of molten material and increase the heat loss due to the long molten material flow path, a heat insulation and moisturizing layer should be added between the low temperature part of the mold cavity and the high temperature part of the molten material flow path.
