注塑模具对产品生产效率的影响

结合注塑管件的生产实际,以生产效率为评价指标,从模具冷却水路设计、模具材料选用、出模数等方面对注塑模具进行研究,结果表明,对产品壁厚处、浇口位置加强冷却,增大型芯冷却面积和冷却水孔尺寸,有利于缩短成型周期,提高生产效率;同时,应用铍铜材料型芯和斜导柱抽芯,以及合理地增加出模数也有利于生产效率的提高。

Influences of Injection Mold on Production Efficiency

According to practical production of pipe fittings and production efficiency was used as evaluation index. The injec-tion mold was studied from cooling waterway design,mold material used and the number of the parts in one mold. The results show that strengthening the cooling wall thickness and gate location of product,increasing large cooling area of core and size of cooling hole can shorten the molding cycle and enhance productivity. At the same time,the use of beryllium copper core and side core-draw-ing of bevel pillar are helpful to improve the production efficiency. Besides,reasonably increase the number of the parts in one mold can improve the production efficiency,also.
