[0030] The following is a further detailed description of the invention objectives and technical solutions of the present invention with reference to the drawings and specific examples, but the present invention is not limited to this example.
[0031] According to the part structure ( figure 1 ) Design the mold structure. The design includes not only injection molding cavity (fixed mold cavity 106, movable mold cavity 206), but also corresponding gating system (such as fixed mold runner 104, fixed mold runner 105, movable mold runner 204) and demolding system (Such as thimble hole 205). The dimensional accuracy and surface roughness of the light-curing mold core are higher than the accuracy required for manufacturing plastic parts. At the same time, the outer dimensions of the shell mold core should be kept unchanged during the backfilling process, so the mold core shell thickness is 2 -5mm, while removing a non-matching surface of the core.
