Description

technical field [0001] The invention relates to the field of injection mold design and processing, in particular to the processing technology of precision assembly parts of digital camera lens barrel plastic molds. Background technique [0002] In the design of the digital camera lens barrel mold, the core part is composed of 1 core seat and 6 core sliders. The outer wall of the 6 core sliders has a thin structure and low strength. The core slider and the core seat adopt the sliding fit of the dovetail groove structure, and the matching clearance is required to be within 0.01 mm, so as to ensure the dimensional accuracy of the plastic parts. On the other hand, after the parts are assembled, the dimensional accuracy of the outer diameter of the entire core part is required to be controlled at 0.005 mm, and the cylindricity of the parts is required to reach 0.01 mm. From this analysis, such strict technical requirements require a new scientific and rational design of parts pr...
