Abstract

Separation of the mold by three basic components,each forming part,is the type plate,a template.it also include a component part,support and sustain its agencies,and its institutions.such a design of course part of the mold and the basic structure of part of the same mould.plastic injection mould a process is a recycling process.this process has four important stage￡oto mould,compacted,cooling,and a plastic mould.from the funnel of the machines to heat,moulding plastics,plastic molding forming technology began to fill the resin and suitable ingredients.to die cavity was full of mold is to type of aggregate and the molten￡?compacted together in a seemly congealed,to a cavity into a high pressure will get down to pay a seemly expected to shrink￡?Cooling is the hottest of the aggregation and cool, its degree of hardness to the top of the final stage is to launch￡?at this stage,the first time,plastic mould it was the top out, and to mould tool and enter the next cycle.
To be designed over the side of the electric fan switch socket plastic mould,many important design contents must be taken into consideration. these factors are maintaining a large number,type a and type a level,a distributary road systems,casting system,and introduce the system.These are my graduation project for the main content.
