Abstract

公开了一种用脱模剂涂覆模腔的方法，该方法能确保脱模剂粘结在腔上。该方法包括一个将由对模有粘结性的材料制成的第一层涂到模腔上的步骤；一个在第一层上面形成由对第一层的材料有粘结性的材料制成的第二层的步骤；以及一个将由对第二层的材料有粘结性的材料制成的且将使被模制的零件能从其上易于脱离的第三层涂在第二层上面的步骤。

Description

用脱模剂涂覆模腔的方法
本发明涉及一种金属模，且，更特殊地，涉及在其模腔上涂覆多层脱模剂的方法。
金属模具有一个腔，用来将其形状传递给熔融金属。为了防止被模制的零件在脱离时粘结，金属模腔必须用一种脱模剂进行涂覆。
图1所示为将一种脱模剂涂覆到金属模(SKD61)腔上去的常规方法。在此法中，在金属模11在被预热到约250℃～300℃后，脱模剂，如一种陶瓷材料，通过采用一个气喷枪14被喷涂到到腔12上，采用这种方式，腔被覆盖且形成一层厚度200～500μm的涂层13。
然而，在这样一种方法中，由在用作脱模剂的陶瓷材料和金属模(SKD61)之间存在一个较大的热膨胀系数差，涂层容易从金属模上脱落。
因此，本发明的一个目的是要克服现有技术的不足，提供一种能使被涂的脱模剂保持粘结在金属模上的在金属模腔上涂覆脱模剂的方法。
为了完成本发明的目的，本发明要提供了用脱模剂涂覆模腔的方法，该方法包括：
(a)将由对模有粘结性的材料制成的第一层涂到模腔上；(b)在第一层上面形成由对第一层的材料有粘结性的材料制成的第二层；且(c)将由对第二层的材料有粘结性的材料制成、且将使被模制的零件能从其上易于脱离的第三层涂在第二层的上面。
具体地，本发明提供一种用脱模剂涂覆模腔的方法，该方法包括下列步骤：
(a)将由5-10％的Al和90-95％的Ni制成的第一层涂到模腔上：(b)在第一层上面形成由1-5％的Al、30-40％的Ni和45-55％的ZnO2和10-20％的MgO制成的第二层；(c)将由15-40％的MgO和85-60％的ZnO2制成的第三层涂在第二层的上面；以及，(d)在涂了第三层后于1000℃-1200℃进行0.5-3小时的热处理。
采用本发明所述的方法，能确保被涂的脱模剂保持粘结在金属模上。
从下面结合附图对优选实施方案的详细描述中，本发明的上述和其他目的和特征将变得明显，附图中：
图1为说明一种常规的涂覆方法的一个示意性剖面图；且
图2为说明一种根据本发明的涂覆方法的一个示意性剖面图。
参见图2，所示为说明一种根据本发明的用脱模剂涂覆金属模腔的方法和示意性剖面图。
首先，金属模(SKD61)被加热到一个预定的温度。通过采用一个等离子体喷枪30，将一种对金属模21的模腔22有强烈粘结性的材料，比如，5-10％的铝(Al)和90-95％的镍(Ni)喷涂到腔22上，由此形成具有厚度范围为10～60μm的第一层23。
接着，通过采用一个等离子体喷枪30，将一种对第一层23的材料有强烈粘结性的材料，比如，1-5％的铝(Al)，30-40％的镍(Ni)，45-55％的ZrO2和10-20％的MgO喷涂到第一层23上，此形成第二层24。第二层24的厚度在10-60μm范围之内。
然后，通过采用一个等离子体喷枪30，将对第二层24的材料的强烈粘结性并将使被模制的零件易于脱离的材料，比如15-40％的MgO和85-60％ZrO2喷涂到第二层24上，由此形成第三层25。第三层25具有的厚度在10-60μm范围内。
最后，在1000℃-1200℃进行0.5-3小时热处理，改进上述各层的粘结性。更具体地，热处理使每一层的组分在它们之间扩散，而这一点又降低了金属模和多层脱模剂之间的热膨胀系数差别，从而防止了多层涂覆剂从金属模上脱落。
尽管仅针对某些优选实施方案对本发明进行了描述，在不偏离后面的权利要求中所提出的本发明的精神和范围的情况下，可以进行其他修正和变化。
