护坡模具会出现的问题和处理方法
发布人:管理员   发布时间:2020-12-4

护坡模具具是现代社会离不开的建材,是比较热销的产品,模具可以循环使用一百多次,可能会出现变形,所以使用中将模具挨着,防止出现变形。
Slope protection mold is a building material that cannot be separated from modern society, and it is a popular product. The mold can be recycled for more than 100 times, which may cause deformation. Therefore, the mold should be placed next to each other to prevent deformation.

护坡模具的材料一般为透明或者半透明的塑料,如果其中夹杂着很多的黑色,红色,暗黄色斑点,而且表面的加工痕迹特别明显,则可以证明这个厂家生产的护坡模具根本就不符合要求。
The material of slope protection mold is generally transparent or translucent plastic. If there are many black, red, dark yellow spots mixed in it, and the surface processing trace is particularly obvious, it can be proved that the slope protection mold produced by this manufacturer does not meet the requirements.

    

护坡模具表面有软点,模具热处理后表面有软点,将影响模具的耐磨性、减少模具的使用寿命,产生原因是因为模具在热处理前表面有氧化皮、锈斑及局部脱碳,模具淬火加热后,冷却淬火介质选择不当,淬火介质中杂质过多或老化。
There are soft spots on the surface of the slope protection mould, and there are soft spots on the surface of the mould after heat treatment, which will affect the wear resistance of the die and reduce the service life of the die. The reason is that there are oxide skin, rust spots and local decarburization on the surface of the die before heat treatment. After quenching and heating, the cooling medium is not selected properly, and there are too many impurities or aging in the quenching medium.

要想预防以上问题,模具设备热处理前应去除氧化皮、锈斑,在淬火加热时适当保护模具表面,应尽量采用真空电炉、盐浴炉和保护气氛炉中加热,护坡模具淬火加热后冷却时,应选择合适的冷却介质,对长期使用的冷却介质要经常进行过滤,或定期更换。
In order to prevent the above problems, the oxide scale and rust spots should be removed before the heat treatment of the die equipment. The mold surface should be properly protected during quenching and heating. Vacuum electric furnace, salt bath furnace and protective atmosphere furnace should be used as far as possible. When cooling the slope protection mold after quenching and heating, the appropriate cooling medium should be selected. The cooling medium used for a long time should be filtered or replaced regularly.
