れる。That is, a mixed powder consisting of glass powders with different softening points is heated at a temperature above the softening point of the low softening point glass powder and below the crystallization start temperature of the same powder (hereinafter referred to as the densification temperature).
A glass powder molded body is obtained by heating and pressure molding. Then, the glass powder molded body is taken out from the molding die and heat treated at a temperature below the softening point of the high softening point glass powder to achieve crystallization, thereby obtaining a crystallized glass material. According to this method, the air in the powder is removed along the particle surface of the high softening point glass powder, so that a dense crystallized glass material with almost no remaining pores or air bubbles can be obtained.
上記の方法を具体的に実施するには、まず、第３図に示
すように成形用金型２１の内周面に、型の剥離のために
アルミナ粉末や黒鉛粉末などの離型材を塗布する。To specifically carry out the above method, first, as shown in FIG. 3, a mold release agent such as alumina powder or graphite powder is applied to the inner peripheral surface of the molding die 21 in order to release the mold. .

性が極めて悪い。(Problems to be Solved by the Invention) The above method for producing a crystallized glass material has the following problems. That is, although the mixed powder is charged into the molding die 21 using a feeding device such as a vibrating feeder or a screw conveyor, the mixed powder 23 is fed into the molding die 21 due to poor feeding efficiency. After that, before inserting the upper mold 22, it is necessary to perform a so-called leveling operation to increase the packing density of the powder and flatten the surface, resulting in extremely low productivity.

ある。(Means for Solving the Problems) The present invention, which has been made to achieve the above object, stores glass powder to be supplied to a mold in a container formed by a synthetic resin film 6. The sealed molded body 11 is sealed in a deaerated state. Further, when the sealed molded body is supplied to the mold, a mold release material 16 is applied to the outer peripheral surface of the sealed molded body 11.

下を余儀な（される。(Function) In the sealed molded article of the present invention, the glass powder is encapsulated in a synthetic resin film and degassed, so the glass powder is in close contact with each other without an organic binder. It is held in shape by friction. Therefore, when supplying glass powder to the mold,
It is sufficient to supply the molded product in units of molded bodies, and there is no need for a break-in operation after supply. Incidentally, during hot molding, the synthetic resin film quickly thermally decomposes and disappears. If the shape of the glass powder is maintained using an organic binder, it will take a long time to thermally decompose the organic binder during hot molding, which will inevitably lead to a decrease in productivity.

If the mold release material 16 is applied in advance, the sealed molded body 11 can be supplied as is without cooling the mold, even after the glass powder molded body has been removed from the mold at a high temperature. That is, glass powder can be supplied to a high-temperature mold, improving productivity.

On the other hand, a cylindrical sheet made of a synthetic resin film 6 and having one end fused and sealed is attached to the opening of the mold part 13. Then, the mixed powder 1 is passed through the deaeration hole 5.
By extruding the mixed powder into the cylindrical sheet through the opening of the mold part 13 while deaerating the air in the powder 5, the mixed powder was wrapped in a synthetic resin film 6 and deaerated to become solid. An airtight packing body 14 of mixed powder 15 can be obtained. Then, while moving on the transport port-sea 9, the shape of the packed body 14 is corrected by thickness and width adjustment rollers 7.8 into a predetermined shape that can be stored in the mold 12, and then degassed. Cutting and fusing device 1 while maintaining the condition
Cut according to the mold size using 0. At this time, the cutting operation is performed while sealing the cut opening to prevent air from entering the film. By continuously performing such an operation, the sealed molded body 11 is continuously manufactured.

かつ確実に行なうことができる。In addition, since the mold release material 16, which is stable at high temperatures, is applied to the outer periphery, the synthetic resin film 6 forming the molded body 11 softens quickly when the sealed molded body 11 is supplied to the molding die. Alternatively, since melting is further prevented, the operation of supplying the sealed molded body to a high-temperature molding die can be carried out safely and reliably.
