摘要：本文通过对塑件进行一系列相应的工艺分析及结构分析，从产品结构的工艺性、实用性、低成本等各方面考虑，并且依据具体的模具结构出发，首先设计该模具为一模两腔。根据搅拌杯盖的实际形状选择了相对合理的分型面分型，采用了滑块与斜导柱装置进行侧抽芯，还设置了推杆进行搅拌杯盖的脱模，并对模具的浇注系统、冷却系统、模具成型部分的结构、注射机的选择以及相关参数的校核都有详细的设计计算。此次设计还运用了AutoCAD、UG绘图软件完成了模具的二维图纸设计及三维建模。本次设计的模具虽然结构较简单，但是工作可靠，并且在一定程度上可以达到搅拌杯盖所要求的质量和加工工艺，本次设计的一些模具图在实际应用生产中也具有一定的指导意义。48117

 The improvement of the shape of the mixing cup cover and the mold design

Abstract: This article through to the process of making a series of corresponding parts analysis and structure analysis, from the technology of product structure, practicability, low cost and so on various aspects to consider, and on the basis of the die structure of concrete, design the mould for one module and two cavities in the first place. According to the actual shape of the refrigerator bottle under the seat chose a relatively reasonable parting parting surface, the slide block and side core-pulling, device of oblique guide pillar and is also equipped with push rod for the refrigerator bottle under the seat ejection, and the mold of gating system, cooling system, mold molding part of the structure, selection of injection machine and related parameters of checking are detailed design calculation. This design is to use AutoCAD, UG, drawing software to complete the mold 2 d drawings and 3 d modeling. Although the design of the mould structure is simple, reliable work, however, to some extent, and can achieve the refrigerator under the bottle of the required quality and processing technology, the design of some mould figure in the practical application of production also has a certain guiding significance.
