    塑胶模具钢材在镶件时需要热处理吗?

    来源:/ 日期:2022-05-19 发布人:admin


    塑胶模具钢材是制造塑胶模具产品时,所需要使用到的一种钢材产品。它通过相关处理后,如热处理、渗氮处理、外表强化处理等后,可以获得更好的性能。那么塑胶模具钢材在镶件时需要热处理吗?
    Plastic mold steel is a kind of steel product that needs to be used when manufacturing plastic mold products. It can obtain better performance after relevant treatment, such as heat treatment, nitriding treatment, surface strengthening treatment and so on. Do plastic mold steel need heat treatment when inserting parts?
    一般来说,塑胶模具钢材在出厂前,都是现已进行了热处理的,其热处理不仅易于抛光,并且能保证加工后获得较高的形状和尺寸精度。但是因为模具使用的不断广泛,关于模具的寿命和精度要求都很高时,就需要对型腔进行渗氮等外表处理或者 对内模镶件进行热处理。
    Generally speaking, plastic mold steel has been heat treated before leaving the factory. Its heat treatment is not only easy to polish, but also can ensure high shape and dimensional accuracy after processing. However, because the mold is widely used, when the requirements for the service life and accuracy of the mold are very high, it is necessary to carry out surface treatment such as nitriding on the cavity or heat treatment on the inner mold insert.
    其热处理过程如下:
    The heat treatment process is as follows:
    1、淬火。
    1. Quenching.

    需要将塑胶模具钢材加热Ac3或Ac1以上某一温度,保温,然后再进行快速冷却后,可获得马氏体或者是下贝氏体安排。
    The plastic mold steel needs to be heated to a certain temperature above AC3 or AC1, kept warm, and then quickly cooled to obtain martensite or lower bainite.
    2、回火。
    2. Tempering.
    将淬火后的塑胶模具钢材进行加热到Ac1以下某一温度,然后保温到安排转变后,再进行冷却到室温。
    Heat the quenched plastic mold steel to a temperature below AC1, and then heat it until it is arranged to change, and then cool it to room temperature.
    3、退火。
    3. Annealing.
    将塑胶模具钢材加热到恰当的温度,保温到必定时刻,然后再缓慢冷却到室温。
    Heat the plastic mold steel to the appropriate temperature, keep it warm for a certain time, and then slowly cool it to room temperature.
    4、正火。
    4. Normalize.
    将塑胶模具钢材进行加热到Ac3或AcGM以上30~50℃,保温必定时刻,然后于在停止空气中进行冷却。
    Heat the plastic mold steel to 30 ~ 50 ℃ above AC3 or ACGM for a certain time, and then cool it in the stop air.
