摘要
提出了一种上模整体镶嵌式分流挤压模结构。这种结构是由四件组成的分流模,有别于传统的二件式或三件式结构。这种新的模具结构的关键要素,主要是将传统的一个上模分解成两个上模,上模之间通过镶嵌的方式进行组合。通过一个实际的LED灯管铝型材作为例子,对这个产品的特性和传统的的模具结构进行分析,详细描述了新的模具结构有关参数的选择,主要包括两个上模的结构及分流孔设计、前导分流板的结构与分流孔设计以及焊合室与工作带的选择等。结果表明,这种上模整体镶嵌式分流模结构是有效的,是具有明显优势的,是一种值得复制推广的模具结构。
A new porthole extrusion die named integral inlay and type in the male die for A1- profiles was presen- ted. The porthole die structure is composed of four parts, which is different from the traditional two or three piece structure. The key structure parameters of the new die were introduced. Mainly one male die was divided into two male dies, and the two dies were assembled by inlaying. Through a practical LED lamp aluminum profile, the characteristics of this product and the traditional die structure are ana- lyzed. The selection of these parameters were described in detail, mainly including the structure of two male dies, the design of portholes, the structure of the front feeder plate, the chamber and the bearing belt etc. The results show the new die structure is effective, it has the obvious advantages, it is a die structure which is worth of being copied and popularized.
