This mould design abstract content is "mineral water bottle cap injection molddesign". The reason of choosing this design topic mainly has two aspects: 1,the plastic bottle cap is threaded, requirements must be considered when designing to release way, multiple sub surface structure and gate way die structure design method; 2, the cap is small, there are general and representative. In our daily life, laid the foundation for future practical mold design, mold manufacturing to service better service society. The design content is from parts of the process analysis, to determine the general designaccording to process requirements. The start is selected from the parts of thematerial, the next is to determine the rate of forming parameters, density,shrinkage, calculating the die types and die design, plastic precision of sizeand structure of the relationship, the choice of injection machine, mold designabout the size (determined by including the mold core and tolerance), injection molding machine checking parameters, mold design, mold cooling, heating system, the calculation of injection mould standard parts of the selection andassembly technology requirements etc..
Die structure design is one of the main content of this design, including the design and layout of mold surface selection, the sprue and runner, ejecting mechanism, guide mechanism, design and processing method and attentionpoints of important parts hinge design and a series of mold. This is more conducive to processing line operation, make it easy and convenient processing. This design not only let me know the textbook knowledge, but alsolet me do apply what they have learned into practice, let me understand the plastic mold design of the various points throughout the process and processing practice. Hope this design to lay a good foundation for future work.
