| 中文摘要: |
| 为了减少修模次数、缩短模具制造周期，应用Moldflow软件对中心罩注射成型中可能形成的缺陷进行了分析，并对注射模进行了优化设计。由于中心罩属于深腔塑件，为了保证塑件的质量模具采用了轮辐式浇口,为使冷却充分，在设计冷却水路时，加设了挡板水路。根据分析结果，所设计的模具流动平衡性良好，气穴、熔接痕、制品温差等均在合理范围内，经生产实践验证模具设计合理。这种模具分析方法与思路对类似产品的注塑模具设计具有一定的参考价值。 |

| To reduce the mold repair times and shorten the manufacturing cycle,the defects which may be formed during injection forming of center cover were analyzed by Moldflow software.The optimum design of injection mold was carried out.Due to the center cover was deep cavity injection part,in order to guarantee the quality of injection part,the spoke gate was adopted in die.In order to cool sufficiently,the plate waterway was added when designing cooling waterway. The analyzing results show that the designed die have good equilibrium flow;the air pocket,melt line and difference in temperature of injection part are all within reasonable ranges. The production practice showed that the design of the die structure is reasonable. This analyzing method and thought can give reference for injection mold designing of similar products. |
