Forming die for vibration isolating support seat

A molding die holder in isolation. It relates to an improved vibration damping mount a laminated molding die. Plate can adapt to the low flatness requirements, and can produce a high precision finished. Includes a lower disk-shaped die, the cylindrical mold, the upper mold and the disc-shaped cylindrical mandrel, further comprising a platen, a platen is provided with a bottom surface of the annular bead; upper mold facing the top surface of the mold should be provided inner cylinder a circle groove, a groove against an outer edge of the bottom surface of the recess positions are evenly distributed a plurality of elongated injection press hole, the inner cylinder of the injection molding pressure in the communicating hole, and the outer edge of the injection mold in the press hole in the corresponding cylindrical surface; annular bead and groove connection active. The present invention can effectively control the dimensional accuracy of the finished product, so that a constant volume of product size. When the user completely avoid "originality" based on the error.
