供氧面罩外壳凸凹模对模成型模的设计与制造

Oxygen Mask Shell Punch for Design and Manufacturing of Mold Molding Mold

供氧面罩外壳是一种由玻璃钢织物和树脂胶为材料,在成型模上进行裱糊后固化的零件。在通过对单模的成型工艺分析,发现这种成型方法会使供氧面罩外壳产生形状扁塌的现象,还会有起皱、脱胶、聚胶和气泡等缺陷。由于供氧面罩外壳批量小,采用喷射接触成型工艺方法,又因投资过大的原因而放弃。通过对供氧面罩外壳成型工艺过程的详细分析,确定采用对模成型的工艺方法进行成型加工。实践也充分地证明了采用对模成型工艺方法来制造供氧面罩外壳,不仅能够确保供氧面罩外壳的质量要求,而且具有操作简单,加工便利,投资低的特点。

Oxygen mask shell is composed of a glass steel fabric and resin as the material, themolding mold on paperhanging after curing parts. In the molding process of single mode throughanalysis, found that the molding method will make the oxygen mask casing shape collapsephenomenon, there will be a wrinkle, degumming, poly glue and bubbles and other defects.Because the oxygen mask shell small batch, using spray contact molding process method, and thereasons for the excessive investment and give up. Through a detailed analysis of the oxygen maskshell molding process, determined by the process of molding the molding processing. Practicehas fully proved that the use of mold process method for manufacturing oxygen mask shell, cannot only ensure the quality of oxygen mask housing requirements, and has the advantages ofsimple operation, convenient processing, the characteristics of low investment.
