都知道生锈模具对整个塑件都会造成质量问题,塑料模多用工具钢制成,在工作中它要遇到腐蚀性气体、水等导致生锈的物质,因此要这种问题排除。
All know rust mold for the plastic parts can cause the quality question, plastic mold multi-purpose tool steel, which it wants to meet in a work lead to rust material such as corrosive gas, water, therefore to eliminate this problem.

 
(1)熔体分解产生的气体.
(1) the melt decomposed to produce gas.

 
有些原料加热后会产生挥发性气体,这些气体多带腐蚀性,它们会对模具产生腐蚀。因此,设备停止工作时,应用软布将模具擦净,并闭合模具,若较长时间不用时,模腔内要喷防锈剂,在关闭模具时还要涂上黄油,堵上浇口。
Some raw material after heating will produce volatile gas, the gas more corrosive, they will have corrosion on the mold. Therefore, equipment to stop working, use soft cloth wipe the die, and closed mold, if long time need not when, cavity to spray anti-rust agent, coated with butter, even when in closed die gate on the wall.

 
(2)模具中的冷却水.
(2) the cooling water in mold.

 
模具中多采用冷却水以进行冷却,因此成型设备周围水气较多。如将模具冷却到露点以下,空气中的潮气就会在模具表面结成水珠,如不及时擦去就易生锈。特别是在模具停止工作后,会很快产生冷凝水。因此,停止成型时,也要关闭冷却水,并将模具擦干。
Mold with cooling water for cooling, so more moisture around the molding equipment. If the mould cooling below the dew point, moisture in the air will be formed in the mold surface water, such as not timely wipe go easy to rust. Especially in the mold after stop working, will soon produce condensate. Therefore, stop molding, also want to close the cooling water, and dry mold.

 
(3)成型时产生的碳化物.
(3) when the carbide forming.

 
模具在较长时间工作后,成型材料中析出和分解生成碳化物,常使模具磨损、腐蚀或生锈。对此,若发现有碳化物生成,应立即清除干净。
Mold after a long time job, molding materials generated carbide precipitation and decomposition, often makes die wear, corrosion or rust. To this, if found to have carbide generated, should be removed immediately.
