である。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass block such as a glass foam, a tile block, a brick block, and the like.
The present invention relates to a frame mold for molding a block-shaped molded product such as a concrete block and a sand mold for casting. 2. Description of the Related Art FIGS. 3 and 4 show a frame mold 11 for forming a plate-like glass foam block. This type of frame includes a cylindrical frame 12 and a bottom frame 13 for closing the bottom.
The cylindrical frame 12 can be disassembled by connecting means such as bolts. After the block is formed, the frame 12 can be disassembled to remove the formed block. That is, the frame body 12 has four plate-shaped side members 12a to 12
The corners of 12d are joined by corner members 14 and fixed with bolts 15. By removing the bolts 15, the side members 12a to 12d and the corner members 14 are disjointed, and the molded block is released. Can be. [0003] When molding a molded article such as a glass foam block, a glass raw material is put into a frame mold, and then the frame mold is heated to about 800 ° C to melt the raw material. Cool slowly. When the frame mold and the molded product are cooled, the thermal expansion coefficient of the glass is smaller than that of the metal, so that the molded product is in a state of being compressed by the frame mold, and cannot be easily removed from the mold (take out the molded product). As shown in FIGS. 3 and 4, there has been no alternative but to make the frame 12 completely disassembled. [0004] The above-described conventional frame mold 11 is provided with the side members 12a to 12d by removing the bolts 15 when removing the mold.
The corner members 14 must be disassembled into pieces, and when molding again, each of the side members 12a to 12d and the corner members 14 must be assembled with bolts 15, and the work efficiency of demolding and assembly is extremely poor. Was. An object of the present invention is to solve such a problem and to provide a frame having a high efficiency of removing and assembling work. The present invention provides a cylindrical inner frame which can be divided so that a molded product can be removed from the mold, and a cylindrical outer frame which is fitted to the inner frame from above to restrict displacement of the inner frame in an outward direction. A frame, a bottom frame for closing the bottom of the inner frame, an outer peripheral portion of the inner frame has an inclined portion inclined upward, and an inner peripheral portion of the outer frame has an inclined portion of the inner frame. In the frame type having a downwardly sloped portion corresponding to the , the inner frame and the outer frame have a quadrilateral shape,
The inner frame is divided into four side members, and each side member is
Note that it is shorter than the inner dimension of the side of the corresponding outer frame.
It is a frame type to be a symbol . [0007] Since the outer peripheral portion of the inner frame has an inclined portion inclined upward, and the inner peripheral portion of the outer frame has an inclined portion inclined downward corresponding to the inclined portion of the inner frame, a molded product is formed. The outer frame can be easily pulled out to the upper part even when the is compressed in a frame shape. After extracting the outer frame, the inner frame is divided and the molded product can be taken out. It is desirable that the inclination angles of the inclined portions of the inner frame and the outer frame be 1 ° or more. When assembling the frame, after setting the inner frame into a cylindrical shape, the outer frame may be fitted over the outer frame from above. Since the displacement of the inner frame in the outward direction is regulated by the outer frame, the inner frame can withstand the internal pressure during molding. As described above, the frame mold of the present invention has excellent work efficiency because it is not necessary to operate bolts and nuts at the time of demolding and assembling. When a molded article having a quadrilateral planar shape is formed, the inner frame and the outer frame have a quadrilateral shape. At this time, it is assumed that the inner frame is divided into four side members. Can be shorter than the inner dimension of the side of the corresponding outer frame. By doing so, a slight gap is formed between the outer frame and the inner frame at the corner, and this gap facilitates the removal of the outer frame during demolding. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments. FIG. 1 shows a frame mold 1 of the embodiment.
FIG. 2 is a partial sectional view of the frame mold 1. The frame mold 1 is for molding a square plate-like glass foam block, and includes an inner frame 2, an outer frame 3, and a bottom frame 4, and these members are made of stainless steel. The inner frame 2 includes four plate-like side members 2a to 2d. As shown in FIG. 2, the outer surfaces of the side members 2a to 2d (the outer peripheral surface of the inner frame 2).
Is an inclined portion 8 inclined upward. The lower end of the outer side surface of each of the side members 2a to 2d is a vertical surface 8 '. Each of the side members 2a to 2d is erected on the outer peripheral portion of the bottom frame 4 in a tube shape, and has a tubular shape. The outer frame 3 is formed by connecting the corners of four plate-shaped side members 3a to 3d with a corner member 5 and integrating them into a rectangular tube. The side members 3 a to 3 d and the corner member 5 are connected by bolts 6. As shown in FIG. 2, each side member 3a-3
The inner surface of d (the inner peripheral surface of the outer frame 3) is an inclined portion 9 inclined downward. The inclination angles of the inclined portions 8 and 9 are both about 4.6 °. The outer frame 3 is fitted over the inner frame 2 erected in a cylindrical shape from above. As a result, the displacement of the inner frame 2 in the outward direction is restricted. Since the lower end of the outer surface of each of the side members 2 a to 2 d of the inner frame 2 is a vertical surface 8 ′, a gap 10 is formed at the lower end of the inner frame 2 and the outer frame 3. This allows
The removal of the outer frame 3 during removal from the mold becomes easy. The side members 2a to 2d of the inner frame are shorter than the inner dimensions of the sides of the outer frame corresponding to these side members, so that there is a gap between the outer frame 3 and the inner frame 2 at the corner. 7 have occurred. This gap 7 Therefore, removal of the outer frame 3 at the time of demolding is further facilitated. In the assembled state shown in FIG. 1, the raw materials are put into the inner frame 2, heated to melt and foam the raw materials, and then gradually cooled. At the time of removal from the mold, the cylindrical outer mold 3 is pulled upward, but can be easily removed by the action of the inclined portions 8 and 9 and the gaps 7 and 10. After the outer die 3 is pulled out, the side members 2a to 2d of the inner frame 2 are pulled out outward. Finally, the molded article and the bottom frame 4 are separated and the molded article is taken out. When assembling the frame mold 1, first, the bottom frame 4
The side members 2a to 2d of the inner frame are erected in the shape of a tube on the outer peripheral portion of the inner frame. Next, the outer frame 3 may be fitted over the inner frame 2 erected in a cylindrical shape from above. Thus, the removal of the frame mold 1,
Assembly work is very easy. The frame mold of the present invention can be easily removed even when the molded article is compressed by the frame mold. In addition, since the demolding and assembling operations can be performed without operating bolts and nuts, the working efficiency is excellent.
