Add to ORKGThe master’s thesis deals with the design of an injection mould for manufacturing of a plastic bottle cap with a child safety lock. Firstly, the analysis of the part is done including a detailed specification of its function and criteria, which have to be fulfilled. After the technology is chosen (injection moulding), the analysis of the injection moulding technology and the problematics of design process is provided. In the following practical part of the thesis, the particular mould for the given part is fully designed using simulation and technological calculation. On the basis of the acquired parameters of the mould, the injection machine was chosen. At the concussion of the thesis, the technical and economical evaluation of the propose...
