所在单位 composed of four parts. The conical shape of the main channel is good for the flow of melt and pouring mold material when the main channel smooth pull up. Main channel directly affects the size of the melt flow rate and filling time. In addition, because of its high-temperature melt and plastic injection molding machine nozzle repeatedly lifted, so the design midfield designed to replace the removable gate sets.
. This requirement does not allow plastic deformation defects and cracks, the surface quality requirements. I choose four-cavity mold injection, to facilitate adjustment of the shear rate and die at closing time, I choose side gate. The cross-sectional shape is simple, easy processing, easy to fix after the tryout, and the opening in the sub-type surface, the feed from the edge of the cavity.
After the injection molding of plastic parts, plastic parts in the mold cooling, due to volume contraction, tight package of core power generation, when it was introduced from the mold, it must overcome the bag tight friction force generated. On the bottom of the barrel, non-porous, shell type plastic parts, mold release when they overcome the atmospheric pressure. Core of the molding ends, generally to design stripping slope, the other, the beginning plastic parts ejection, the ejection force required for the largest, followed by the introduction of the role of force is introduced to overcome the machine only for the organization moving of friction. The plastic parts are putting Stripping.
  Finally, use CAD to draw all of the parts assembly drawings and diagrams, and dimensioning, technical requirements very manufacturing standards.
Keywords: injection mold, mold design, preserves box
