摘要
针对挤出 1个管坯吹塑 1个塑件传统工艺 ,提出了中小型中空塑件的单管坯多型腔成型方法。通过对挤出机头、吹塑模具结构设计和成型工艺的研究及实验 ,解决了多型腔的排布、塑件壁厚均匀、提高结合缝强度、防止坯料粘合、塑件与余料自动切断。
A technique for multi-cavity blow molding based on single parison was proposed. The extrusion die and blowing mold were specially designed. The cavities were properly arranged so that the uniformity of the walls of the products, the strength of the seam, the auto-separating of the products from excessive material, and the air-escaping were ensured.
