The injection molding process of plastic hangers can be roughly divided into six stages: “mold closing-injection molding-pressure holding-cooling-mold opening-plastic hanger disassembly”. If the above process is repeated, the product can be produced continuously. The first simulation test can produce multi-cavity molds, and can produce a variety of boom products. At present, in the mold processing process, most of the hanging molds that take one out of two and one out of four are produced.
At present, hanging molds do not seem to be classified according to mold processing technology. But we all know that different styles and different materials of booms have different methods in terms of mold description, processing, and production. Therefore, the classification of the spreader mold is mainly carried out according to the classification of the spreader. Roughly divided into: women’s hangers, suit hangers, children’s hangers, pet hangers, bra hangers and other processing procedures.
1, bottom surface processing, processing quantity guarantee;
2, blank benchmark alignment, 2D and 3D mold surface allowance inspection;
3, 2D, 3D contour roughing, non-equipment non-operating surface processing (including safety platform surface, buffer device surface, pressure plate surface, side reference surface);
4. Before semi-finishing, the alignment of the side reference surface can ensure the accuracy;
5. Semi-finishing machining of 2D and 3D contours, various device operating surfaces (including stopper device surface and contact surface, insert device surface and back, punch device surface, waste tool device surface and back, tension spring device surface and contact surface ) Finishing, various stroke limit operation surface, wedge mounting surface and backside), various guiding surfaces, semi-finishing of guiding holes, and reserve the finishing process reference hole and height reference, and record the data;
6. Check and review the machining accuracy;
7, the fitter setting process;
8. Before finishing, align the reference surface of the technical reference hole and check the margin of the insert;
9, finishing contour two-dimensional, three-dimensional, side punching contour and hole position, finishing process reference hole and height reference, finishing guide surface and guide hole.
