Description
Technical field
The utility model is related to a kind of USB injection molds based on CAE technologies.
Background technology
Injection mold is a kind of instrument for producing plasthetics；Also plasthetics complete structure and accurate dimension are to confer to
Instrument.Injection molding is to produce a kind of processing method used during some complex-shaped parts in batches.Refer specifically to melt heated
Plastics by injection machine high pressure inject die cavity, after cooling and solidifying, obtain formed products.
Forming process numerical simulation is the basis in mould CAE, at present, and the method for numerical simulation used mainly has two
Kind：FInite Element and finite difference calculus.For the shaping of general simple injection-molded item, flow simulating analysis is only carried out,
But for the shaping of complex precise plastic, not only sunykatuib analysis is carried out to flow process, in addition it is also necessary to mold filling, pressure maintaining period
The cooling of middle plastic and mould is analyzed, or even needs to analyze the residual deformation and stress of plastic after die sinking.
The USB terminals that conventional USB terminal injection molds are produced, because mould does not carry out simulation and the dynamic point of precision
Analysis, therefore, the product accuracy of injection molding is poor, service life is short.
