随着制造业的快速发展，塑料模具在塑料成型加工中的需求越来越大，其在模具产量中的比重也逐年增加。下面来讲讲塑料模具钢的性能要求以及材料选择。

With the rapid development of manufacturing industry, the demand of plastic mold in plastic molding processing is increasing, and its proportion in mold output is also increasing year by year. Now let's talk about the performance requirements and material selection of plastic mold steel.

塑料模具钢的性能要求

Performance requirements of plastic mold steel

塑料模具受温度和压力的影响。同一塑料模具有多种失效形式，同一模具可能出现多种损伤，因此应合理选择模具材料和材料性能

Plastic moulds are affected by temperature and pressure. The same plastic mold has multiple failure forms, and the same mold may have multiple damages, so the mold material and material properties should be reasonably selected

质量将直接影响模具的使用寿命。因此，在模具钢的性能上，根据塑料模具的工作条件，选择时应综合考虑耐热性、热处理、耐磨性、可加工性、热稳定性、耐腐蚀性等。模具钢耐热性好，可以保证模具钢在使用过程中满足精度要求；模具钢热处理性能高，可有效防止模具失效。

Quality will directly affect the service life of the mold. Therefore, in terms of the performance of mold steel, according to the working conditions of plastic mold, the selection should comprehensively consider heat resistance, heat treatment, wear resistance, machinability, thermal stability, corrosion resistance, etc. The die steel has good heat resistance, which can ensure that the die steel meets the accuracy requirements in the process of use; Die steel has high heat treatment performance, which can effectively prevent die failure.

热处理在整个模具的制造过程中起着重要的作用，因此应选择热处理变形小、淬火温度范围宽、过热敏感性小的模具钢。在塑料中加入一些无机材料可以增加塑性，但同时也会对模具造成磨损，因此对模具钢的耐磨性有一定的要求。透明塑料件在成型过程中，对材料性能要求较高，选用的模具材料必须具有较高的镜面加工性能，材料中非金属夹杂物和气孔较少，微观结构均匀。超纯钢满足上述要求，热处理后硬度高，是成型透明塑料件的良好塑料模具材料。随着社会生产力的提高和人们物质文化需求的增加，购买者希望塑料制品的表面可以装饰出美丽复杂的图案，并且所使用的塑料模具材料的图案具有更好的可蚀刻性。

Heat treatment plays an important role in the whole mold manufacturing process. Therefore, die steel with small heat treatment deformation, wide quenching temperature range and low overheating sensitivity should be selected. Adding some inorganic materials to plastic can increase plasticity, but it will also cause wear to the mold, so there are certain requirements for the wear resistance of mold steel. During the molding process of transparent plastic parts, the requirements for material properties are high. The selected mold materials must have high mirror processing performance, less non-metallic inclusions and pores in the materials, and uniform microstructure. Ultra pure steel meets the above requirements and has high hardness after heat treatment. It is a good plastic mold material for forming transparent plastic parts. With the improvement of social productivity and the increase of people's material and cultural needs, buyers hope that the surface of plastic products can be decorated with beautiful and complex patterns, and the patterns of plastic mold materials used have better etchability.

塑料模具钢材料的选择应根据模具的工作条件综合考虑，以避免塑料模具在工作中的故障，保证生产效率。在成型生产过程中，对于生产批量小、精度要求低的塑料件，可以使用rot钢等低碳钢；对于生产批量大、质量要求高的塑料件，模具结构复杂，应选用技术要求高的低淬火钢。

The selection of plastic mold steel materials should be comprehensively considered according to the working conditions of the mold, so as to avoid the failure of the plastic mold in the work and ensure the production efficiency. In the process of molding production, low carbon steel such as rot steel can be used for plastic parts with small batch production and low precision requirements; For plastic parts with large batch production and high quality requirements, the mold structure is complex, and low quenching steel with high technical requirements should be selected.

在一些塑料零件的成型过程中，当达到成型温度时，会产生大量的腐蚀性气体。所以在处理这类成型塑料模具时，对接触腐蚀性气体的零件材料的选择会比较严格，要求有较好的耐腐蚀性。

In the molding process of some plastic parts, when the molding temperature is reached, a large number of corrosive gases will be produced. Therefore, when dealing with this kind of molding plastic mold, the selection of part materials in contact with corrosive gases will be relatively strict, and better corrosion resistance is required.

另外，如果想用普通材料代替耐腐蚀材料，需要对加工后的普通材料进行镀铬处理，以保证不会被腐蚀性气体腐蚀，不影响塑料模具的使用。

In addition, if you want to replace corrosion-resistant materials with ordinary materials, you need to chrome the processed ordinary materials to ensure that they will not be corroded by corrosive gases and will not affect the use of plastic molds.

塑料模具钢在工业应用和生产中需求量很大，大多数是用低碳钢或低碳低合金钢冷挤压成型的标准件。更多内容就来网站https://www.jnqhmj.com咨询吧。
