模具喷洒

    第一步是在所有板的背面(有沉孔)喷洒防锈剂的保护涂层,因为在过去已经观察到背面特别脏或者在模具常规生产运转中被锈蚀。接近光亮和快速干燥的中等负载防锈剂在短期运转(如小于等于250,000次或大约60天)下工作的很好。如果在出现长期运转、严重凝结而厂房没有控制湿度的手段,或者模具长期搁置不用,就需要使用更重负载的蜡状防锈剂。
  所有的浇注口和任何其它暴露在内部凝结或重度污染的部件需要涂层。防锈剂还能很好得用于不锈钢平板上,因为它通过减少氧化和使得残留物被超声清除得更快。
  保护暴露的型腔模免受防锈剂的过量喷洒是至关重要的,因为这会引起严重的粘结或渗溶;因此,应该注意模具维护手册上关于什么样的板需要涂层的清单和如何进行可靠涂层的程序。一旦已经应用了涂层并已经干燥,就可开始装配。
  举例用的模具是由六个板组成的包含型芯、脱模衬套、齿轮和齿条以及止推片、轴瓦和方形密封圈载一起的冷端或“B”面。部件在安装时的顺序与拆开时的相反。模具的高温端或“A”面由型腔板与分歧管板配对组成。

The first step is at the back of all the board (there is Shen-hole) antirust protection spray coating, because in the past have been observed at the back especially dirty or die operation of conventional production was corroded. Bright and quick-drying near the middle-load operation in the short term anti-rust agent (such as less than or equal to 250,000 or about 60 days) under a good job. If long-term operation in the event of a serious condensation and humidity control plant not a means of long-term dormant or die, we need to use a heavier load Antirust cereus.
Pouring all I and any other exposed internal condensation, or heavily polluted parts of the coating required. Antirust was also very good for the stainless steel plate, because it makes by reducing the oxidation and removal of residues by ultrasonic faster.
Protection from exposure to mold cavity Antirust excessive spraying is critical, as it would cause serious or bond percolation melting;, therefore, should pay attention to mold maintenance manual on the board about what kind of a list of required coating and how reliable coating procedures. Once the coating has been applied and has dried, you can begin assembly.
For used molds are composed of six panels contains the core, Demoulding Bushing, gear and rack and the thrust piece, bearing and seal set with a square of the cold-side or "B" side. Components in the order of installation and the opposite when opened. High-temperature mold side or "A" Noodles by the cavity plate and tube plate matching the composition of their differences.
