Title: Positioning structure of mold
Inventor: KUMASHIRO AKIRA
IPC: B29C33/30
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To keep the reliability of the positioning of split molds by means of bushings in positioning holes and positioning pins fitting to the holes for a long period of time. SOLUTION: Each positioning hole 11 opened in a portion in the neighborhood of each one of four corners of a split mold 10 has an elongated circle extending to the direction of a straight line passing through the center of the split mold 10. Both the inner surfaces in the direction of a short diameter of the elongated circle are planar parts 11a parallel to that straight line. To each positioning hole 11, a bushing 12 is fitted movably to the direction of that straight line under the state that its both side planar parts 121a come into close contact with the planar parts 11a of the positioning hole 11.  As a result, at mold closing, even when the axis centers of the positioning pins 21 and of the bushings 12 of a split mold 20 shift each other due to the difference between the thermal expansions of the split molds 10 and 20, the bushings 12 move to the concentric positions of the split molds to the directions of the straight lines during the inserting process of the positioning pins 21 for self-alignment, resulting in developing no seizure.

Abstract: PURPOSE:To project a vertical light beam on a medium at all times and to make the distance between the medium and an optical pickup constant by providing plural inclined fulcrums on the tilting mechanism tilting the optical pickup according to the inclination of the light projecting position of a recording medium. CONSTITUTION:When a video disk 12 is bent downward, a tilting cam 25 is rotated in counter-clockwise direction to turn the left end of a tilting lever 17 in the lower direction. At this time the fulcrum pin 27a at the right side of a pressing spring 22 is abutted to the lower end of the corresponding hole of the lever 17. This point becomes the fulcrum and an optical pickup 19 is inclined to the left. On the other hand, when the disk 12 is bent upward, the cam 25 is rotated in clockwise direction and the lever 17 is turned upward. At this time the fulcrum pin 27b is abutted to the lower end of the corresponding hole, this point becomes the fulcrum and the pickup 19 is inclined to the right. A vertical light beam is projected on the disk always by holding plural fulcrums and also the distance between the disk and pickup is thus made constant.
