注塑加工企業(yè)技術(shù)人員指出，在注塑加工過程中模具的溫度是否適宜會直接影響到注塑產(chǎn)品的尺寸精度、外觀、內(nèi)在質(zhì)量及產(chǎn)品生產(chǎn)效率，由此可見模具溫度的重要性。
The technicians of injection molding enterprises pointed out that whether the mold temperature is appropriate in the injection molding process will directly affect the dimensional accuracy, appearance, internal quality and product production efficiency of injection molding products, which shows the importance of mold temperature.
注塑加工需要溫度調(diào)節(jié)系統(tǒng)來達(dá)到產(chǎn)品溫度的要求。溫度調(diào)節(jié)系統(tǒng)根據(jù)不同的情況可以分為冷卻系統(tǒng)和加熱系統(tǒng)兩種。一般情況下，注塑到模具內(nèi)的塑料溫度為200度左右，而注塑件成型后從模具型腔中取出時的溫度在60度以下。
Injection molding requires temperature regulation system to meet the requirements of product temperature. Temperature regulation system can be divided into cooling system and heating system according to different conditions. In general, the temperature of the plastic injected into the mold is about 200 degrees, while the temperature when the injection molded part is taken out of the mold cavity is less than 60 degrees.
熱塑性塑料在注塑成型后，必須對模具進(jìn)行有效的冷卻，使得塑料的熱量快速的傳遞給模具，從而使得注塑件冷卻后能夠盡快的脫模。
After the injection molding of thermoplastic, the mold must be cooled effectively to make the plastic heat transfer to the mold quickly, so that the injection molded parts can be demoulded as soon as possible after cooling.
對于那些熔融塑料黏度較低、流動性較好的塑料，如聚乙烯、尼龍和聚苯乙烯等，如果注塑件的邊壁比較薄，則模具可以進(jìn)行自然冷卻。如果注塑加工模具的邊壁比較的厚，則需要人工進(jìn)行冷卻，使得注塑件能盡快的定型，提高生產(chǎn)效率。
For those plastics with low viscosity and good fluidity, such as polyethylene, nylon and polystyrene, if the side wall of the injection molded part is relatively thin, the mold can be cooled naturally. If the side wall of the injection mold is relatively thick, it needs to be cooled manually, so that the injection parts can be shaped as soon as possible and improve the production efficiency.
注塑加工時注塑模具每一階段的溫度是需要注塑人員監(jiān)控的，要熟練掌握加熱和冷卻系統(tǒng)對模具調(diào)節(jié)溫度的方法。只有做到嚴(yán)格控制，才能使得注塑加工的過程中順利進(jìn)行，生產(chǎn)出合格的產(chǎn)品。
During injection molding, the temperature of each stage of the injection mold needs to be monitored by the injection molding personnel. It is necessary to master the method of adjusting the temperature of the mold by the heating and cooling system. Only by strict control can the injection molding process be carried out smoothly and produce qualified products.
