Porsity and shrinkage cavity defects on die castings of motorcycle boxesare introduced , some solutions are used , the results prove that correct runnersare important for decreasing of boxes ' defects 主要采取的解决措施是对压铸模内浇口的设置和右端型芯进行修改。
The cross section area of the internal sprue of the die casting dies designed should be of proper value , and matches perfectly the fill speed , the fill time and injection pressure in case that the die casting dies fail in the design 设计压铸模时应当确定恰当的内浇道截面积,并使之与充填速度、充填时间和压射比压保持较好的匹配,以防止压铸模设计的失败。
In order to solve the problem of the difficulty for the complicated shell in stripping away from the mould , the technical trait of the complicated shell has been analyzed , the twi - ejector using stripper plate and ejector sleeve has been designed , the mould operational principle and the structure trait have been discussed , and the die casting machine has been selected based on the swelling force calculation 摘要针对复杂壳体压铸件难以脱模的问题,分析了复杂壳体的工艺特性,设计了卸料板、推管二次推出压铸模,论述了模具工作原理和结构特点,并且通过胀型力的计算选择了压铸机。
