模具制作影響精度的四個方面,模具加工精度直接影響了模具的質量,而影響模具加工精度的因素主要有三個方面,主要為尺寸精度、形狀精度和位置精度,并且這三者還有很重要的關系.
There are four aspects that affect the precision of mold making. The precision of mold processing directly affects the quality of mold. There are three main factors that affect the precision of mold processing, which are dimension precision, shape precision and position precision, and there is a very important relationship among them
1.尺寸精度,指加工后零件的實際尺寸與零件尺寸的公差帶中 心的相符合程度.尺寸精度是用尺寸公差來控制的.尺寸公差是模具加工中零件尺寸允許的變動量.在基本尺寸相同的情況下,尺寸公差與愈小,則尺寸精度愈高.
1. Dimensional accuracy refers to the degree of conformity between the actual size of the part after processing and the tolerance zone center of the part size. Dimensional accuracy is controlled by dimensional tolerance. Dimensional tolerance is the allowable variation of the part size in mold processing. In the case of the same basic size, the smaller the dimensional tolerance is, the higher the dimensional accuracy is

2.形狀精度,指東莞模具加工后的零件表面的實際幾何形狀與理想的幾何形狀的相符合程度.評定形狀精度的項目有直線度、平面度、圓度、圓柱度、線輪廓等6項.形狀精度是用形狀公差來控制的,各項形狀公差,除圓度、圓柱度分13個精度等級外,其余均分12個精度等級.1級高,12級低.
2. Shape accuracy refers to the degree of conformity between the actual geometry and the ideal geometry of the part surface processed by Dongguan mold. Six items of shape accuracy are evaluated, including straightness, flatness, roundness, cylindricity and line profile. Shape accuracy is controlled by shape tolerance. All shape tolerances are divided into 13 precision grades except roundness and cylindricity, The rest are divided into 12 Accuracy grades. Grade 1 is high and grade 12 is low
3.位置精度,指黃江模具加工后零件有關表面之間的實際位置精度差別.評定位置精度的項目有平行度、垂直度、傾斜度、同軸度、對稱度、位置度、圓跳動和全跳動等八項.位置精度是用位置公差來控制的,各項目的位置公差亦分為12個精度等級.
3. Positional accuracy refers to the actual positional accuracy difference between the relevant surfaces of parts processed by Huangjiang mould. The items to evaluate positional accuracy include parallelism, perpendicularity, inclination, coaxiality, symmetry, positional degree, circular runout and total runout. Positional accuracy is controlled by positional common error, and the positional tolerance of each item is also divided into 12 Accuracy grades
4.尺寸精度、形狀精度和位置精度的關系.通常在設計機器零件及規定零件加工精度時,應注意將形狀誤差控制在位置公差內,位置誤差又應小于尺寸公差.即精 密零件或零件重要表面,其形狀精度要求應高于位置精度要求,位置精度要求應高于尺寸精度要求.
4. The relationship among dimension accuracy, shape accuracy and position accuracy. Generally, when designing machine parts and specifying the machining accuracy of parts, attention should be paid to controlling the shape error within the position tolerance, and the position error should be less than the dimension tolerance. That is to say, for precision parts or important surfaces of parts, the shape accuracy requirements should be higher than the position accuracy requirements, and the position accuracy requirements should be higher than the dimension accuracy requirements
如今各行業對模具的質量要求愈來愈高,所以對模具加工的要求也隨之提高,這就需要我們了解影響模具加工精度的各種因素,提高模具質量.濟南l立強模具制造有限公司您值得信賴!
Nowadays, the quality requirements of mold in various industries are getting higher and higher, so the requirements of mold processing are also increasing, which requires us to understand various factors affecting the accuracy of mold processing, and improve the quality of mold. Jinan Liqiang mold manufacturing Co., Ltd. you are trustworthy!
