压铸模具还要试模,这是为什么呢?

来源:http://www.jnhjgs.cn     发布时间:2019-10-16 16:03:13    点击:

  压铸生产中经常遇到新产品开发和旧模具更新。压铸件的内外质量一般取决于压铸件的工艺参数,如液态金属温度、压铸压力、速度、速度开关点等。但大多数情况下,还与模具设计、制造关系密切相关。影响模具的因素,包括型腔数、浇注系统设计、浇口类型(位置和尺寸)、浇注结构。为了防止模具设计引起的铸造缺陷,并检查和纠正模具制造中的一些问题,有必要对成品模具进行测试。
  New product development and old mold renewal are often encountered in die casting production. The internal and external quality of die casting generally depends on the process parameters of die casting, such as liquid metal temperature, die casting pressure, speed, speed switch point, etc. However, in most cases, it is also closely related to die design and manufacturing. The factors that affect the mold include the number of cavities, the design of the gating system, the type of gate (location and size), and the gating structure. In order to prevent casting defects caused by mold design and to check and correct some problems in mold manufacturing, it is necessary to test the finished mold.
  压铸模具试验及工艺参数优化
  Die casting die test and process parameter optimization测试的主要目的是找出优化工艺参数和模具修改计划,请求即使数据元素,如癫痫、机器设置,或环境改变,还能确保模具能稳定和不连续的大规模生产合格的产品,更大限度地提高模具的进展“合规”,不仅是一个试图得到一些好的特性。

  The main purpose of the test is to find out the optimized process parameters and mold modification plan, and request that even if the data elements, such as epilepsy, machine settings, or environmental changes, can ensure that the mold can stably and discontinuously mass produce qualified products, and further improve the mold progress "compliance", which is not only an attempt to get some good features.

  1. 找出模具存在的问题
  1. Find out the existing problems of the mold模具厂完成模具制作后,都要有良好的“合规性”(即成型参数或工艺条件是否宽裕)模具。但由于设计思路不佳或制造过程加工不足,经常出现尺寸超差、过渡部分进水、施工不当等问题,导致铸件生产不合格或模具试制失败。模具检测是发现模具问题更简单、直接、有效的方法。
  After the mold factory completes the mold making, it must have good "compliance" (that is, whether the molding parameters or process conditions are abundant) mold. However, due to the poor design idea or the insufficient processing in the manufacturing process, problems such as out of tolerance dimension, water inflow in the transition part and improper construction often occur, resulting in the unqualified casting production or the failure of mold trial production. Mold inspection is a more simple, direct and effective way to find mold problems.
  1. 找出更佳成形条件
  1. Find out better forming conditions
  模具测试的过程中,模组测试人员可以找出更合适的过程数据,和可以使用的数据集的默认值设置机器参数在批量生产中,根据更优工艺条件为批量生产的模具可以调整。
  In the process of mold testing, the module tester can find out more suitable process data, and can use the default value of the data set to set the machine parameters in the mass production, according to the better process conditions for the mass production of mold can be adjusted.
  1. 验证CAE辅助设计,提高后续工作效率
  1. Verify CAE aided design to improve follow-up work efficiencyCAE分析软件,是对真实机床、真实合金性能和真实外部环境的规范,通过计算机仿真,得到仿真结果。模具设计人员根据仿真的情况,对模具设计做出相应的修正;在实机试模中,可以直接将仿形数据作为预设值输入,使试模人员可以检查仿形模具设计是否存在缺陷。将测试模块的缺陷与仿真结果进行对比分析,为后续工艺参数的设置提供依据。
  CAE analysis software is the specification of real machine tool, real alloy performance and real external environment. Through computer simulation, simulation results are obtained. According to the simulation situation, the mold designer makes the corresponding modification to the mold design; in the real machine mold test, the profiling data can be directly input as the preset value, so that the mold tester can check whether there are defects in the profiling mold design. The defects of the test module are compared with the simulation results to provide the basis for the subsequent process parameters setting.
