Technical Problem
对于一些异型结构的塑料管道，如梅花管，其管材周壁具有特殊的异型结构，并不平整，因此在塑料挤出、管材定型等工序需要严格控制加热熔融温度、挤出速度、冷却成型温度、定型抽真空度等，否则容易因加热熔融温度、挤出速度、冷却成型温度等不匹配而造成异型管材的表面产生皱褶，无法实现良好定型
Benefits of technology
高温的异型管材由围设有多个冷却模块的定型管一端进入至定型管内部，利用预冷组件对高温异型管材实施预冷却。预冷却后的异型管材继续被推动至定型管另一端，即定型管没有围设多个冷却模块的部分，这个过程中由于异型管材外侧的定型腔区域的气压低于异型管材内侧的气压，使异型管材的管壁被吸向定型腔的周侧，实现对异型管材的定型。由于异型管材在定型前先被预冷组件实施预冷却，使异型管材的温度降低，提升此时异型管材的硬度，因此能够降低异型管材实施定型时受挤出速度与高温柔软状态的共同影响，减少异型管材的表面产生皱褶的情况，实现良好定型。由于对异型管材实施了预冷却，减少定型工序中异型管材受加热熔融温度、挤出速度、冷却成型温度、定型抽真空度等的影响，提升成型速度，对操作工人的技术要求较低，操作工人更容易上手。多个冷却模块围设于定型管的周侧，能够对定型管的沿周向的各个位置同时实施预冷却，避免定型管沿周向的不同位置所受到的冷却效果差异过大，避免因定型管沿周向不同位置的预冷效果不一而影响成型效果，提升成型质量。
