する。Reference numeral 9 indicates a pressure rod that presses the upper mold 1 during pressure molding. When pressure molding an optical element using the above-mentioned apparatus, the molding material 10 is inserted into the pressure molding chamber 6, The upper mold 1 is placed on top of the mold, and the mold into which the molding material 10 is inserted is heated as a whole, or by the above-mentioned radiant heating devices 7 and 8,
After heating the portion 3a of the mold 3 into which the above molding material 10 is inserted, and thereby softening the molding material 10 by heating,
The pressurizing rod 9 is driven by a pressurizing rod driving means (not shown) to push down the upper mold 1 and release the molding material 1 in the pressurizing molding chamber 6.
By compression molding 0, a desired optical element is molded.

点を有し、現在、広く用いられるようになってきた。The above-mentioned pressure molding method for optical elements has the advantage of shortening the manufacturing time of optical elements compared to conventional grinding and polishing methods, and is now widely used.
しかし、この方法によると成形用素材１０が、加圧変形

形用素材と成形型が接触することになる。そのために、
第７図に示すよりに成形用素材と成形用金型の接触面に
気泡１１が発生するという問題が生じる。However, according to this method, the molding material 10 comes into contact with the mold at a high temperature during a long heating time until the molding material 10 reaches a temperature at which it can be deformed under pressure. for that,
As shown in FIG. 7, a problem arises in that bubbles 11 are generated at the contact surface between the molding material and the molding die.

題も生じる。On the other hand, the weight of the upper mold 1 of the molding die and the softening of the molding material 10 increase as the temperature reaches a temperature that can change the pressure and the molding material is in contact with the molding die before pressure molding. Due to self-deformation, a part of the molding surface of the upper mold 1 and/or lower mold 2 is transferred to the molding material 10 before pressure molding,
A boundary portion in the form of a step 12 or the like is generated on the surface of the molding material. This step 12 and the like remain on the functional surface of the optical element after molding, resulting in a problem that accurate transfer of the molding surface of the mold is prevented.

黴面積を少なくする方法が採用されているが、この方法
では成形用素材の製作に多額の費用と高度な技術が要求
され、経済的な面や技術的な面で解決しなければならな
い多くの問題点が生じる。Therefore, a method has traditionally been adopted to reduce the area of mold tangent to the mold by changing the shape of the molding material, but this method requires a large amount of money and advanced technology to produce the molding material. Many problems arise that need to be solved economically and technologically.

気泡等の欠陥が発生する。Furthermore, a method has been proposed in which the molding material 10 is held floating between the upper mold 1 and the lower mold 2 and heated, but in this method, the upper mold and the lower mold become as hot as the molding material. During pressure molding, defects such as bubbles occur on the contact surfaces between the molding material 10 and the upper mold 1 and lower mold 2.
