  模具,素有“工业之母”的称号。它主要经过所成型材料物理状态的改动来完成物品外形的加工。模具没做好,问题都在这十条!
  Mold, known as the "mother of industry" title. It is mainly through the change of the physical state of the formed material to complete the processing of the object shape. Mold is not done well, the problems are all in these ten!
  1.模具钢材
  1. Die steel
  钢材是模具质量的决议性要素,选择合理的钢材是重中之重。选择钢材的规范是:
  Steel is the decisive factor of mold quality, and the most important thing is to choose a reasonable steel. The specifications for steel selection are:
  ①注塑材料的请求——不同的塑料要选用不同的钢材,如对高抛光的请求、耐腐蚀的请求等等;
  ① requirements for injection molding materials: different plastics should be made of different steels, such as the requirements for high polishing, corrosion resistance, etc;
  ②价钱——钢材功用够用就好,不是越贵越好;思索到模具的本钱要素,模具钢材要选用和模具寿数相应的材料,避免不用要的糟蹋;普通P20的寿数在30万左右;2738寿数在50万没问题,H13/2344通常在80-100万以上,可以依据状况选择;
  ② price - steel is good enough, not the more expensive the better; considering the cost elements of the mold, the mold steel should choose the materials corresponding to the mold life to avoid unnecessary waste; the life of ordinary P20 is about 300000; 2738 life is 500000, no problem, H13 / 2344 is generally more than 800000-1 million, which can be selected according to the situation;
  ③热处置。模具的表面处置也是非常重要。氮化——可以加强钢材的表面硬度,有用延伸模具寿数;电镀——能对模具钢材停止有用改性,对一些需求高亮度的和耐腐蚀的塑件可以应用电镀来加强和改善钢材的功用。
  ③ heat treatment. The surface treatment of mold is also very important. Nitriding can strengthen the surface hardness of steel and extend the service life of die; electroplating can stop the modification of die steel. Electroplating can be applied to some plastic parts requiring high brightness and corrosion resistance to strengthen and improve the function of steel.
  2.构造设计
  2. Structural design
  干练的模具构造,不光思索到产品材料特性—缩短率、成型温度、弹性拉伸变形系数等,并且还要思索到冷却水路、开合模的速度等。合理的模具构造能有用延伸模具寿数和保证模具的顺畅出产,进步功率,降低本钱。
  The efficient mold structure not only considers the material characteristics of the product - shortening rate, molding temperature, elastic tensile deformation coefficient, but also considers the cooling water path, opening and closing speed, etc. Reasonable mold structure can extend mold life and ensure smooth production of mold, improve power and reduce cost.

  3.模具加工
  3. Mold processing
  工欲善其事,必先利其器。模具工艺的布置尤为重要,合理的工艺布置能加速出产周期,缩短加工时间,有用俭省本钱。并且,更重要的是,精细合理的加工可以保证模具在出产过程的安稳和延伸寿数。加工出错有的会招致模具烧焊,不论焊的多好,对模具来说都是一种损失;另外,加工欠好还有可能影响模具动作,降低模具寿数,招致模具在出产过程中呈现拉裂乃至折断。
  Sharp tools make good work. The layout of mold technology is particularly important. Reasonable layout of technology can accelerate the production cycle, shorten the processing time, and save money. Moreover, more importantly, fine and reasonable processing can ensure the stability and extended life of the mold in the production process. Some processing errors will lead to mold welding, no matter how good the welding is, it is a loss to the mold; in addition, poor processing may affect the mold action, reduce the mold life, and cause the mold to crack or even break in the production process.
  4.规范件
  4. specification
  决议水桶容量的是短根木条。这个道理大家都了解,可是在做的时分,常常会留意不到。模具也是相同,规范件固然不直接参与成型,但却操控着整个模具的运转。好的规范件应该可以耐磨,够硬,精度高,不宜变形。不同品牌的规范件差价很大,所以,做模具不要一味杀价,杀来杀去,你的模具从飞驰就直降至大众了。
  The capacity of the bucket is determined by the short root wood. We all know this truth, but when we do it, we often fail to notice it. The mould is the same. Although the standard parts are not directly involved in the forming, they control the operation of the whole mould. Good standard parts should be wear-resistant, hard enough, high precision and not be deformed. There is a big difference in the price of standard parts of different brands, so don't haggle over the price of making molds. Kill to kill, and your molds will drop to the public from gallop.
  5.对碰(飞模)
  5. Collision (flying mold)
  对碰靠的是模具钳工的阅历,看似简单的活,却是具有技术含量的作业。
  The experience of the die fitter, seemingly simple work, is the work with technical content.
  复杂模具主要看的就是这个功夫。平板模具简单,分形面只需没有飞边断差根本就ok了。像汽车配件模具就非常的费事了,不光分形面比拟不规则,并且常常包含多个滑块、顶块。
  This is the main focus of complex mold. The flat die is simple and the fractal surface only needs no flash and fracture difference. Like auto parts mold is very difficult, not only fractal surface is more irregular, and often contains a number of slider, top block.
  一同,经过对碰,还能对模具的其他问题停止改善和完善,所以它是一项综合性的作业。
  Together, after the collision, it can also improve and perfect other problems of the mold, so it is a comprehensive operation.
  6.抛光/皮纹
  6. Polishing / Dermatoglyphics
  模具的抛光是模具制造的一个重要环节。抛光直接反映到塑件上,所以这是个很面子的作业。抛光还能对模具动作起到辅佐和补充的效果,特别对脱模非常有意义。常常一些模具出产不顺畅,就是由于打光不到位,阻力过大,脱模艰难,乃至顶白、顶裂等。
  Mold polishing is an important part of mold manufacturing. Polishing is directly reflected on the plastic parts, so this is a very face-saving operation. Polishing can also play an auxiliary and supplementary role in mold movement, especially in demoulding. Often some mold production is not smooth, is due to the polishing is not in place, resistance is too large, difficult demoulding, and even top white, top crack and so on.
  7.模具安装
  7. Mold installation
  模具安装就好像组装机器相同,每一个部件,每个螺钉都不能出错,不然,结果会相当严重,轻则招致产品缺陷,影响出产,重则彻底损伤模具,构成报废,所以,安装的活一定要非常的细致。
  Mold installation is the same as assembly machine. Every part and screw can't make mistakes. Otherwise, the result will be quite serious. Light will lead to product defects, affect production, heavy will completely damage the mold, constitute scrap. Therefore, the installation work must be very meticulous.
  安装过程中,特别是要留意模具的清洁作业,特别是水路、螺丝孔,一定要吹干净里边的铁屑,不然客户非常生气的。
  During the installation process, especially pay attention to the cleaning of the mold, especially the waterways and screw holes. Be sure to blow the iron chips inside, otherwise the customer will be very angry.
  8.暖流道仍是冷流道
  8. Warm channel or cold channel
  这个其实对模具质量的影响较小,由于暖流道普通都是客户请求品牌的,特别是一些大客户。国外知名品牌,不论在质量仍是售后效劳上做的都非常到位,所以质量上普通不会有问题,而国内的一些暖流道倒是质量相差很大。个别小企业为了俭省本钱,来争取价钱上的优势,用一些不靠谱的加热和传导配件,就容易出问题。
  In fact, this has little impact on the quality of the mold, because the warm runner is generally requested by customers, especially some big customers. Foreign well-known brands, whether in quality or after-sales service, are very good, so the quality of the general will not be a problem, while some of the domestic warm runner is very different in quality. In order to save money and strive for price advantage, some small enterprises are prone to problems by using unreliable heating and conduction accessories.
  而冷流道主要的问题,就如何保证注塑的均衡、浇口大小、注塑压力等等。
  The main problem of cold runner is how to ensure the injection balance, gate size, injection pressure and so on.
  9.冷却水路
  9. Cooling water circuit
  有过模具阅历的人都晓得,冷却对一个模具来说是多么重要。由于物价和人力工资的增长,在大批量出产产品的时分,每减少一秒的注塑周期所带来的利润都是无法想象的。可是,加速出产周期的一同就会招致模具温度的上升,假设得不到有用操控的话,就会使模具由于太热无法成型,乃至招致模具变形失效报废,所以,优秀的水路设计尤为重要,包含水路的排布密度、直径、互相之间的衔接等等。
  People who have experience in mold know how important cooling is to a mold. Due to the increase of price and labor wage, the profit of every second of injection cycle reduction in mass production is unimaginable. However, the acceleration of production cycle will lead to the rise of mold temperature. If there is no useful control, the mold will be too hot to be formed, or even lead to mold deformation failure and scrap. Therefore, excellent water design is particularly important, including the layout density, diameter, connection between each other and so on.
  10.模具维护
  10. Mold maintenance
  模具维护主要是出产过程中的维护和颐养。
  Mold maintenance is mainly in the production process of maintenance and self-care.
  模具就像汽车相同,假设长时间不用又不加颐养的话,就可能招致模具报废掉,所以,每次模具运用后都要停止全面的颐养,特别是成型局部的防锈,主要动作部件的防锈。由于模具在出产过程中要接水的,可能在安装或拆开过程中有水弄到模具上,所以一定要保证模具的单调,然后再刷一层油维护。
  Mold is like a car. If we don't use it for a long time and don't take care of it, it may lead to die scrapping. Therefore, every time the mold is used, we should stop taking care of it comprehensively, especially the rust prevention of forming parts and main action parts. Since the mold needs to be connected with water in the production process, there may be water on the mold during the installation or disassembly process, so it is necessary to ensure the monotony of the mold, and then brush a layer of oil for maintenance.
