  模具的精度和刚度
  Accuracy and stiffness of dies
  (1)模具精度
  (1) Mould accuracy
  模具的精度包括尺寸精度、形状精度、位置精度和表面粗糙度。模具的精度主要体现在模具零件的精度和匹配精度上。
  The accuracy of die includes dimension accuracy, shape accuracy, position accuracy and surface roughness. The precision of die is mainly embodied in the precision of die parts and matching accuracy.
  模具工作部件的精度高于产品部件的精度。例如,切削刃尺寸的精度比产品零件的精度高。通常测量的精度不是工作状态下的精度(如冲裁间隙),即静态精度。但在工作条件的影响下,静态精度和动态精度转化为动态精度,这是具有实际意义的真实数据。
  The precision of die working parts is higher than that of product parts. For example, the accuracy of cutting edge size is higher than that of product parts. Usually the accuracy of measurement is not the accuracy of working state (such as blanking clearance), that is, static accuracy. However, under the influence of working conditions, static and dynamic accuracy are transformed into dynamic accuracy, which is a real data with practical significance.
  一般模具的精度应配合产品的精度,而且通过模具加工技术手段,随着制造技术的发展,模具加工技术的进步,模具精度将会相应提高,模具零件互换性生产也将成为现实。
  Generally, the precision of die should match the precision of product. With the development of manufacturing technology and the progress of die processing technology, the precision of die will be improved correspondingly, and the interchangeability production of die parts will become a reality.
  (2)模具刚度
  (2) Mould stiffness
  对高速冲压模具、大型件冲压成形模具、精密塑料模具和大型塑料模具都具有重要意义。这种模具的工作负载,当一个较大的弹性变形,不仅影响模具的动态精度,而且相关的模具可以正常工作,所以在模具设计,同时满足强度的要求,应保证模具刚度,同时生产,以避免额外的变形是由于处理不当。
  It is of great significance to high-speed stamping die, large parts stamping forming die, precision plastic die and large plastic die. When a large elastic deformation occurs, not only the dynamic accuracy of the die is affected, but also the relevant die can work normally. Therefore, in the design of the die, while meeting the strength requirements, the rigidity of the die should be guaranteed and the production should be carried out at the same time to avoid additional deformation due to improper handling.
  模具生产周期
  Mold production cycle
  模具生产周期是指从接受模具采购订单到交付后的模具测试合格的模具,目前,压铸模使用企业需求的生产周期短,所以模具生产周期的长度测量模具企业标志,生产能力和技术水平的关系模具企业在激烈的市场竞争中站稳脚跟。同时,模具生产周期的长短也是衡量一个国家模具技术管理水平的一个指标。
  Mould production cycle refers to the qualified mould from accepting the purchase order of the mould to testing after delivery. At present, the production cycle of the die-casting die is short, so the length of the production cycle of the mould measures the logo of the mould enterprise, the relationship between the production capacity and the technical level of the mould enterprise stands firm in the fierce market competition. At the same time, the length of the mould production cycle is also an index to measure a country's mould technology management level.
  影响模具生产周期的主要因素有:(1)模具技术和生产的标准化;(2)模具企业专业程度;(3)模具生产技术先进;(4)模具生产管理水平。

  The main factors affecting the production cycle of die and mould are: (1) standardization of die and mould technology and production; (2) professional level of die and mould enterprises; (3) advanced die and mould production technology; (4) level of die and mould production management.
  模具生产成本
  Mold production cost
  模具生产成本是指企业为模具的生产和销售所支付的费用总额。模具的生产成本包括原材料成本、外协件成本、外协件成本、设备折旧、运营费用等。其本质上分为生产成本、非生产成本和外部生产成本。一般来说,模具生产成本是指与模具生产过程直接相关的生产成本。
  Mold production cost refers to the total cost paid by the enterprise for the production and sale of the mould. The production cost of mould includes raw material cost, external parts cost, external parts cost, equipment depreciation, operation cost and so on. It is essentially divided into production costs, non-production costs and external production costs. Generally speaking, the production cost of mould refers to the production cost directly related to the production process of mould.
  影响模具生产成本的主要因素有:(1)模具结构的复杂性和模具功能的高度;(2)模具精度;(3)模具材料选择;(4)模具加工设备;(5)模具标准化程度与企业生产专业化程度。
  The main factors affecting the cost of die production are: (1) the complexity of die structure and the height of die function; (2) die accuracy; (3) die material selection; (4) die processing equipment; (5) the degree of standardization of die and enterprise production specialization.
  模具寿命
  Die life
  模具的生活指的是零件的总数量,可以加工的前提下保证零件的质量,包括零件加工的数量之和之前和之后的重复磨削表面和易损件的更换工作。一般在模具设计阶段应明确模具适用于批量生产的类型或模具生产的零件总数,即模具的设计寿命。不同类型的模具正常的损伤形式是不一样的,但一般来说,工作面的损伤形式有摩擦损伤、塑性变形、开裂、疲劳损伤、咬伤等。
  Die life refers to the total number of parts, which can be processed under the premise of ensuring the quality of parts, including the sum of the number of parts processed before and after repeated grinding surface and vulnerable parts replacement work. Generally, in the stage of die design, the type of die suitable for mass production or the total number of parts produced by the die should be defined, that is, the design life of the die. The normal damage forms of different types of dies are different, but generally speaking, the damage forms of working face are friction damage, plastic deformation, cracking, fatigue damage, bite and so on.
  影响模具寿命的主要因素如下:
  The main factors affecting die life are as follows:
  (1)模具结构——合理的模具结构有利于提高模具的承载能力,降低模具所承受的机械载荷;(2)模具材料——根据生产零件的尺寸选择;(3)模具加工质量——模具零件在机械加工、电火花加工、淬火和表面处理等方面的缺陷,将对模具的耐磨性、抗咬伤能力和抗断裂能力产生显著影响;(4)模具的工作状态——模具的工作状态、所用设备的精度和刚度、润滑条件、加工材料的预处理状态、模具的预热和冷却条件对模具的寿命有影响;这四个方面的技术指标和经济指标相互影响和制约。在实际生产过程中,应根据产品零件和目标对这些因素进行综合平衡。
  (1) Die structure-reasonable die structure is conducive to improving the bearing capacity of the die and reducing the mechanical load it bears; (2) Die material-selection according to the size of the parts produced; (3) Die processing quality-Defects of die parts in mechanical processing, EDM, quenching and surface treatment, etc., will affect the wear resistance, bite resistance and fracture resistance of the die. Force has a significant impact; (4) The working state of the die - the working state of the die, the accuracy and stiffness of the equipment used, lubrication conditions, the pre-treatment state of the processing materials, the preheating and cooling conditions of the die have an impact on the life of the die; the four technical and economic indicators affect and restrict each other. In the actual production process, these factors should be comprehensively balanced according to the product parts and objectives.
