  模具的精度和剛度
  Accuracy and stiffness of dies
  (1)模具精度
  (1) Mould accuracy
  模具的精度包括尺寸精度、形狀精度、位置精度和表面粗糙度。模具的精度主要體現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產品部件的精度。例如,切削刃尺寸的精度比產品零件的精度高。通常測量的精度不是工作狀態下的精度(如沖裁間隙),即靜態精度。但在工作條件的影響下,靜態精度和動態精度轉化為動態精度,這是具有實際意義的真實數據。
  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.
  一般模具的精度應配合產品的精度,而且通過模具加工技術手段,隨著制造技術的發展,模具加工技術的進步,模具精度將會相應提高,模具零件互換性生產也將成為現實。
  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)模具剛度
  (2) Mould stiffness
  對高速沖壓模具、大型件沖壓成形模具、精密塑料模具和大型塑料模具都具有重要意義。這種模具的工作負載,當一個較大的彈性變形,不僅影響模具的動態精度,而且相關的模具可以正常工作,所以在模具設計,同時滿足強度的要求,應保證模具剛度,同時生產,以避免額外的變形是由于處理不當。
  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.
  模具生產周期
  Mold production cycle
  模具生產周期是指從接受模具采購訂單到交付后的模具測試合格的模具,目前,壓鑄模使用企業需求的生產周期短,所以模具生產周期的長度測量模具企業標志,生產能力和技術水平的關系模具企業在激烈的市場競爭中站穩腳跟。同時,模具生產周期的長短也是衡量一個國家模具技術管理水平的一個指標。
  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.
  影響模具生產周期的主要因素有:(1)模具技術和生產的標準化;(2)模具企業程度;(3)模具生產技術先進;(4)模具生產管理水平。

  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.
  模具生產成本
  Mold production cost
  模具生產成本是指企業為模具的生產和銷售所支付的費用總額。模具的生產成本包括原材料成本、外協件成本、外協件成本、設備折舊、運營費用等。其本質上分為生產成本、非生產成本和外部生產成本。一般來說,模具生產成本是指與模具生產過程直接相關的生產成本。
  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.
  影響模具生產成本的主要因素有:(1)模具結構的復雜性和模具功能的高度;(2)模具精度;(3)模具材料選擇;(4)模具加工設備;(5)模具標準化程度與企業生產化程度。
  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.
  模具壽命
  Die life
  模具的生活指的是零件的總數量,可以加工的前提下保證零件的質量,包括零件加工的數量之和之前和之后的重復磨削表面和易損件的更換工作。一般在模具設計階段應明確模具適用于批量生產的類型或模具生產的零件總數,即模具的設計壽命。不同類型的模具正常的損傷形式是不一樣的,但一般來說,工作面的損傷形式有摩擦損傷、塑性變形、開裂、疲勞損傷、咬傷等。
  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.
  影響模具壽命的主要因素如下:
  The main factors affecting die life are as follows:
  (1)模具結構——合理的模具結構有利于提高模具的承載能力,降低模具所承受的機械載荷;(2)模具材料——根據生產零件的尺寸選擇;(3)模具加工質量——模具零件在機械加工、電火花加工、淬火和表面處理等方面的缺陷,將對模具的耐磨性、抗咬傷能力和抗斷裂能力產生顯著影響;(4)模具的工作狀態——模具的工作狀態、所用設備的精度和剛度、潤滑條件、加工材料的預處理狀態、模具的預熱和冷卻條件對模具的壽命有影響;這四個方面的技術指標和經濟指標相互影響和制約。在實際生產過程中,應根據產品零件和目標對這些因素進行綜合平衡。
  (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.
