厂，嵌入件的加入既可充分利用个种材料的性能例如强度、硬度、耐蚀性、耐磨性、导磁性、导电性等以满足不同条件下使用的要求，又可弥补因铸件结构工艺性差带来的缺点，以及解决具有特殊技术要求零件的压铸问题。 In zinc alloy die-casting plants, the addition of inserts can make full use of the properties of various materials such as strength, hardness, corrosion resistance, wear resistance, magnetic permeability, and electrical conductivity to meet the requirements of use under different conditions, and can compensate Disadvantages due to the poor workability of the casting structure, and to solve the problem of die casting of parts with special technical requirements. However, the inserts used to assist the processing of die castings have strict requirements both in terms of design technical requirements and in the process of use.
件需要铸如的嵌件形状有很多，一般为螺杆、螺母、轴、套、管状制件、片状制件等。 There are many insert shapes that zinc alloy die-casting parts need to be cast, such as screws, nuts, shafts, sleeves, tubular parts, sheet parts, etc. When designing the insert, it is necessary to meet the technical requirements such that the insert is enclosed by the alloy without loosening, and there is no electrochemical corrosion between the insert and the base alloy. Secondly, the insert must not have sharp corners to avoid casting. When cracking occurs, the embedded part must be made with straight, twill, knurling, grooves, protrusions or other structures to enhance the combination of the insert and the die-casting alloy to ensure that the insert is stable and reliable in the casting.
厂使用的嵌入件在压铸前最好能镀以耐蚀性保护层，以防止嵌入件和铸件本身产生电化学腐蚀，其次为不影响压铸件的成型性往往还要将嵌入件预热到一定的温度，锌合金嵌入件一般是预热到 150~200 ℃。 The inserts used in zinc alloy die-casting plants should preferably be plated with a corrosion-resistant protective layer before die-casting to prevent electrochemical corrosion of the inserts and the casting itself. Secondly, the inserts are often not pre-treated without affecting the formability of the die-casting. When heated to a certain temperature, zinc alloy inserts are generally preheated to 150 ~ 200 ° C.
