榨汁机内支架塑料模具设计行业是国民经济的-项重要行业↑年来,模具-直朝着高质量、高效率、低成本、短周期的方向发展。传统的模具设计中,模具设计者们是利用二维CAD软件来进行初步设计的。然而,现在,三维模具设计已经被广泛使用,它使设计过程接近标准化,使初步设计得以迅速实现。在本设计中,将对榨汁机内支架的模具通过Pro/ENGINEER软件进行三维设计,并对设计过程进行讲解。 在本设计中,首先对塑件结构、材料特性、用途以及参数进行分析,确定模具采用-模两腔,并使用点浇口填充型腔的总体布局形式。在模具设计过程中,对侧向抽芯机构,分型面的设计,浇注系统、排气系统、冷却系统、脱模机构,进行了详细的介绍。最后通过对注塑机参数校核和生产验证,证明模具结构设计合理性。 通过本次模具设计,可以看出,三维模具设计可以缩短设计周期,提高设计质量,大大的增加工作效率。 关键字:榨汁机内支架;注塑模具;-模两腔;侧向抽芯机构
ABSTRACT The die and mould industry is an important industry of the national economy. In recent years, mould is developing towards high quality, high efficient, low cost and short- period. In traditional mould design , mould designers was using 2D CAD Software & Tools to proceed the preliminary design . However, 3D mould design already has been used extensively nowadays, which makes mould design approach to standardization and makes preliminary design quickly realize. In this article, it presents 3D mould design for juice-extractor part by Pro/E, and explains its design process in detail. In this design, at first , it have analyzed the plastic part structure , material properties , use , and parameters , ascertained the mould layout form of One to Two cavities , and adopted the general distribution form of pin-point gate filling with cavity. In this mould design process, it has introduced in detail for side Core-Pulling mechanism , the design of parting surface, gating system and venting system, cooling system, ejection mechanism. Finally, through checking and production proofing for molding machine parameters , the mould structure is proved to be reasonability . Through this mould design, it may find out that 3D mould design can shorten design cycle, raise design quality and largely increase the working efficiency. Key words: Juice-extractor part; Plastic injection mould; One mould two cavities; Side Core-Pulling mechanism
