Design of Injection Moulding Tool for the Component
Keywords:
HIPS, 2D drawingsAbstract
This work deals with the Design and Manufacture of Injection Moulding Tool for the Component Press Button in HIPS material by the Screw type Injection Moulding process.The design and fabrication of a mould for the given component is most challenging task in plastic processing in injection molding. It determines the quality, performance and the profitability of a plastic component. The 3D model of the component is created using solid works software. The various views of different parts involved in mold are taken using this software. These views are converted to 2D drawings for easy dimensioning. Design Protocol is on conventional method, based on tried and tested norms Choice of the most appropriate option for the selection of parting line, feeding system, cooling system, venting, etc. are based on the manufacturing point of view. The above parameters help in development of various parts in mold that are functional, reliable, manufacturability and aesthetically pleasing. Manufacturing involves design of electrodes, process planning, machining and assembly. Complete process planning for each part of the tool is not carried for the sake of brevity. After fabrication of the tool, samples of the component were produced. These samples were inspected to find defects, if any.
