Design of Injection Mold for UAV Instrument Case Cover
According to the structural characteristics of the plastic parts of the UAV instrument cover,a sim-plified two-plate injection mold is designed.The mold can be unfolded by 2 parting open and 1 ejecting open respectively.The first part is opened for unlocking the threaded core,the second part is opened for releasing the plastic part from the cavity.Finally,the third part,ejection opening is used to push the plate to eject the plastic part and completely release the mold.It was used to eject the plastic parts with the push plate and completely demould.An active de-threading mechanism based on plastic-steel thread pair was designed in the mold,which can effectively prevent the thread of plastic parts from being damaged when demoulding.At the same time,it is convenient to adjust the starting point setting of the thread.The mold has a good reference value for engineering design.
