Abstract
This graduate design is to the request of the top dust sheet molding tool design, the difference wait to the work zero parts of the molding tool six the parts of big zeros make the detailed design.The main contents of designing includes to wash to cut a piece craft analysis and craft projects really settle, craft calculation, the gearing of the design, molding tool that wash to cut the molding tool and adjust etc..
Compute in the craft the part want to be to the row kind design and calculation, wash the calculation, molding tool pressure of the pressure center to really settle, convex and cave mold size and make sure the calculation that make the business trip and compute the detailed calculation in contents in etc..
Cut the mold to want at the design part that wash to the work spare parts, position the spare parts and unload to anticipate with a spare parts, lead to spare parts conjunction with fix spare parts etc. construction the proceeding the detailed analysis design.Want to be in design process work process of understanding the molding tool with notice to choose to use standardly, to reunite the construction that wash the understanding that cut the mold further have.
The gearing of the molding tool with adjust to try the part want to notice to lead the pillar molding tool to lead the pillar molding tool with gearing method and sequences that have nos, passing the gearing of the molding tool, understanding the molding tool constitute and function etc. of each parts of the parts of zeros.Noticing the molding tool installs to try to wash the familiar blemish of inside of process later on and solution method etc..
Pass this time graduate the design want to have the nearer and one-step understanding to the compound molding tool, while designing to notice the molding tool construction simple, molding tool usage convenience, high etc. in life span in molding tool problem.And increase production efficiency, guarantee the quantity of the product.
Key phrase:The compound mold tries to hurtle the cleft the match transition match
