设计简介
摘 要
随着全球制造业向亚太地区的转移，我国正成为世界制造业的重要基地，作为国民经济的基础工业之一的模具工业将直面竞争的第一线。随着三维图形技术和计算机技术的发展，模具CAD技术也将在其发展中占有越来越重要的地位。我国模具工业的发展将面临新的机遇和挑战。虽然在很多方面我国的模具有了很大的发展，但仍有很多突出的问题。目前模具设计及制造大都依靠设计的经验来设计，模具的质量完全由个人的累积的经验控制，这使得模具设计的周期长，效率低且其质量也难以保证。模具工业除需要“高技艺”的从业人员外，还需要更多的“高技术”来保证。本论文介绍了固体胶底座的注射模设计的过程。从型腔数量和布局的确定、注射机选择、浇注系统设计、模板及其标准件的选用、脱模及抽芯机构的设计、成型部件的设计等一一进行了详细的介绍。

ABSTRACT
With the global manufacturing shift to the Asia-Pacific region, China is the world's important manufacturing base, the national economy as the basis of one of the industrial tooling industry will face competition in the first line. With the 3-D graphics technology and computer technology to the development of CAD technology will also die in their development occupies an increasingly important position. China's mold industry will face new development opportunities and challenges. Although in many respects, China's mold a great development, but there are still many outstanding issues. At present most of die design and manufacturing design experience to rely on the design, die by the quality of all the accumulated experience of personal control, which makes die design of long cycle and low efficiency and it is difficult to guarantee their quality. In addition to mold industry needs "high arts" of practitioners, but also the need for more "high technology" to ensure that. This paper introduced a solid base of the plastic injection mold design process. From the cavity of determining the number and layout, the injection of choice, pouring system design, templates and standards of selection, and Stripping out the core design, shaping the design of components, such as January 1 carried out a detailed introduction.
Key words： Injection Mould; lateral core pulling; after Cover
