摘要：本文主要介绍了以ABS为材料制作的立式空调遥控器下盖的设计方法，其主要是为了满足企业的日常生产需求。运用UG软件进行绘制，对注塑机的选用，浇注系统的设计，型腔数量及布局形式的设计，推出机构等进行设计计算。本文提出了一模四腔的注塑方案，使用侧浇口的成型的方案，同时通过增加支撑柱来加强模具的刚度。通过对遥控器下盖的结构与成型工艺分析，下盖内侧有6个卡扣，提出采用斜推杆来解决模具的脱模与内侧抽。下盖前部有2个需要进行侧抽的方孔，设计用斜导柱和滑块同时安装在动模上的侧抽机构。设计时只需要加长斜导柱，使滑块在侧抽芯的整个过程中不脱离斜导柱即可，因此也不需设置侧滑块定位装置。同时依靠楔形滑块使模具进行复位。43241

 Technology analysis and mould design for the under cover of the remote control of the vertical air conditioner

Abstract: This paper mainly introduces the design method of the vertical air conditioner, which is made by ABS, which is mainly to meet the needs of the daily production of the enterprise. The use of UG software to draw, the selection of injection molding machine, the design of gating system, the number of cavity and the layout of the form of design, the introduction of institutions, such as the design and calculation. In this paper, we put forward a method of injection molding with four cavities, and use the method of side gate to strengthen the rigidity of the mould. According to the analysis of the structure and the forming process of the lower cover of the remote controller, the inner side of the lower cover is provided with 6 clamping buttons, and the inclined push rod is adopted to solve the ejection and the inner side of the mould. At the front part of the lower cover is provided with a side suction side which needs to be carried out at the side of the side of the 2 side. When designing, the sliding block can not be separated from the oblique guide pillar in the whole process of the side core pulling, so that the positioning device of the side sliding block can not be arranged. At the same time, the mold is reset by the wedge sliding block.

Key words: Injection mould; side core pulling mechanism; remote control under cover
