制作模具的相关注意事项
一、不要只重产品设计,忽视模具制造:
First, don't just focus on product design, but ignore mold manufacturing.
有些用户在开发产品或新产品试制时,往往初期只注重于产品研制与开发,忽视与模具制作单位的沟通。产品设计方案初步确定后,即提前与模具厂商接触有两个好处:
When trying to develop products or new products, some users tend to focus only on product development and development, ignoring communication with mold manufacturers. After initial www.kelinbaojie.cn www.dzhlzj.com www.aohailaowu.com www.fanguangmo51.com www.beijingqima.cn www.tianchengwuzi.com.cn4000312797determination of the product design plan, there are two advantages of contacting the mold manufacturer ahead of time.
1、可以保证设计的产品有好的成形工艺,不会因零件难以加工而修改定型设计。
1, you can ensure that the product has a good forming process and will not modify the design because the parts are difficult to machine.
2、模具制作方可提前做设计准备,防止匆忙中考虑不周,影响工期。
2, the mold maker can make design preparations ahead of time, so as to prevent the hasty consideration and affect the construction period.
3、制作高质量模具,只有供需双方紧密配合,才能最终降低成本,缩短周期。
3, the production of high quality mold, only the supply and demand sides closely cooperate with each other, in order to ultimately reduce costs and shorten the cycle.
二、不要只看价格,要从质量、周期、服务全方位考虑:
Two, do not just look at prices, but also consider quality, cycle and service.
1、模具种类很多,大致可分为十大类。根据零件材料、物理化学性能、机械强度、尺寸精度、表面光洁度、使用寿命、经济性等不同要求,选择不同类型的模具成形。
1, there are many kinds of moulds, which can be roughly divided into ten categories. According to the material, physical and chemical properties, mechanical strength, dimensional precision, surface finish, service life, economy and other requirements, different types of die forming are selected.
2、精度要求高的模具需要使用高精度的数控机床加工,而且模具材质、成形工艺都有严格要求,还需使用CAD / CAE / CAM模具技术去设计、分析。
2. High precision mold needs to be processed with high precision CNC machine tools, and the mold material and forming process are strictly required, and the CAD / CAE / CAM die technology should be used to design and analyze.
3、有些零件由于成型时有特殊要求,模具还需使用热流道,气辅成型,氮气缸等先进的工艺。
3, because some parts have special requirements when molding, the mold should also use advanced technology such as hot runner, gas assisted molding, nitrogen cylinder and so on.
4、制造厂家应具备数控、电火花、线切割机床及数控仿型铣设备,高精度磨床,高精度三座标测量仪,计算机设计及相关软件等。
4, manufacturers should have numerical control, electric spark, wire cutting machine and CNC milling equipment, high precision grinding machine, high precision three coordinate measuring instrument, computer design and related software.
5、一般大型冲压模具(如汽车复盖件模具)要考虑机床是否有压边机构,甚至边润滑剂、多工位级进等。除冲压吨位还要考虑冲次、送料装置、机床及模具保护装置。
5, the general large stamping die (such as automobile cover mold) should consider whether the machine tool has a blank holder mechanism, or even side lubricants, multi station progressive. Besides punching tonnage, we should also consider blanking, feeding devices, machine tools and mould protection devices.
6、上述模具的制造手段及工艺不是每个企业都具备和掌握的。在选择协作厂家时一定要了解它的加工能力,不但看硬件设备,还要结合管理水平、加工经验以及技术力量。
6, the manufacturing means and technology of the above mould are not possessed and grasped by every enterprise. When choosing a collaborative factory, it is necessary to understand its processing capacity, not only to see the hardware equipment, but also to combine management level, processing experience and technical strength.
7、对同一套模具,不同厂家报价有时有很大差距。你不该付出高于模具价值费用的同时,也不应该少于模具的成本。模具厂家象你一样,要在业务中取得合理的利润。订制一套报价低得多的模具会是麻烦的开始。用户须从自身要求出发,全面衡量。
7, for the same set of mold, different manufacturers sometimes offer a big difference. You should not pay more than the cost of the mold, nor should it be less than the cost of the mold. Mold manufacturers, like you, have to make reasonable profits in business. Ordering a set of moulds that offer much lower prices will be the beginning of trouble. The user must set out from its own requirements and measure it in an all-round way.
