注塑beplay全站app安卓在现代工业生产中具有很重要的作用,其质量直接决定产品的质量。可是,注塑beplay全站app安卓在生产应用过程中,经常发生各种不同情况的失效,浪费大量的人力、物力,影响了beplay全站app安卓加工的生产进度和经济效益。因此,改进注塑beplay全站app安卓,提高beplay全站app安卓的使用寿命,是一个急需解决的问题。
Injection mold plays an important role in modern industrial production, and its quality directly determines the quality of products. However, in the process of production and application of injection mold, various failures often occur, which wastes a lot of manpower and material resources, and affects the production progress and economic benefits of mold processing. Therefore, improving the injection mold and increasing the service life of the mold is an urgent problem to be solved.
较易操作的工艺方案:采用标准模块作为beplay全站app安卓初始加工基础,分粗、精两道工序完成机加工。粗加工留1.5-2mm 量,热处理消除内应力后再进行精加工,将机加工内应力降到低,以保持模块长久尺寸的稳定性。beplay全站app安卓标准化生产得到普遍推行,模架应用非常广泛。模架进厂前根据用户要求精定位设置,导向装置等已准确加工到位。即便发生机械加工内应力变形,已不能利用热处理的工艺方法去消除工件存在的内应力。为保证装配精度之要求,进行机械加工修正几何形变,这种方案在理论上就存在着不严谨性,明显的几何形变虽然得到修正,但因加工应力的作用使导向装置产生的变位并未得以修正,金属内应力并不因机械修正几何形状而消失。

Easy to operate process plan: the standard module is used as the initial processing basis of the mold, and the machining is completed in two processes: rough and fine. 1.5-2mm is reserved for rough machining, and the internal stress is eliminated by heat treatment before finishing machining, so as to reduce the internal stress of machining to a low level, so as to maintain the long-term dimensional stability of the module. Die standardized production has been widely promoted, and die base is widely used. Before entering the factory, the mold base is set according to the user's requirements, and the guide device has been accurately processed in place. Even if there is internal stress deformation in machining, the internal stress of workpiece can not be eliminated by heat treatment. In order to meet the requirements of assembly accuracy, the scheme of machining to correct geometric deformation is not rigorous in theory. Although the obvious geometric deformation has been corrected, the displacement caused by the guide device has not been corrected due to the effect of machining stress, and the internal stress of metal does not disappear due to the mechanical correction of geometric deformation.
beplay全站app安卓在生产中受各种不确定因素影响和自身原因,模块加工残留内应力始终在释放,而导致动定模变形。随着动定模模块变形,密合面出现不规则变化,飞刺逐渐增多加大。另一方面呈现在顶出机构上。顶出杆运动由畅顺无侧壁摩擦,随模块变形增加顶杆逐渐发生侧壁摩擦,直至出现热粘合现象。内应力释放的过程就是模块二次变形的过程。应力系数越大,释放越快,beplay全站app安卓失效越快。
Due to the influence of various uncertain factors and its own reasons, the residual internal stress of the module is always released, which leads to the deformation of the dynamic and fixed die. With the deformation of the moving and fixed die module, the sealing surface changes irregularly, and the flying spikes increase gradually. On the other hand, it appears in the ejection mechanism. The movement of ejector rod is smooth without side wall friction. With the increase of module deformation, the side wall friction of ejector rod gradually occurs until the phenomenon of thermal bonding occurs. The process of internal stress release is the process of module secondary deformation. The larger the stress coefficient, the faster the release and the faster the die failure.
