Sludge casting refers to supplying slurry to the molding space inside a casting mold made of plaster, allowing the slurry to adhere to the surface of the plaster mold using the water absorption effect of the plaster, and draining the unadhered slurry from the molding space. By curing for a predetermined period of time, the water content of the inking slurry is further absorbed into the plaster mold, which lowers the moisture content of the inked area and hardens until it has a hardness that allows it to maintain its shape.Then, the mold is removed and the molded product is created. This is the way to obtain.

臨んでいる。 The present applicant has filed a patent application in Japanese Patent Application No. 57-91046 for a technology that can be used repeatedly and significantly shorten the molding time regarding the sludge casting device used in the above method. As shown in FIG.
2a, 2b, and filtering material layers 3a, 3b made of gypsum or the like formed on the inner surface of each,
A drainage channel 5 is provided inside the upper and lower filtering material layers 3a and 3b.
a and 5b are buried. And drainage channel 5
At least one end of each of a and 5b communicates with the outside of the pressure vessels 2a and 2b via external piping 8a and 8b. A slurry supply pipe 6 is attached to the lower pressure-resistant container 2b, and its tip is connected to the filtering material layer 3.
It faces the molding space 4 formed inside the parts a and 3b. Further, an overflow pipe 7 is attached to the upper pressure-resistant container 2a, and its tip also faces the molding space 4.

る。 According to the above-described slurry casting device 1, after supplying slurry, the inside of the pressure container 2 is pressurized, and the drainage channels 5a and 5b are connected to the atmosphere or a negative pressure source, thereby controlling the deposition speed and deposition rate of the slurry. The increased diffusion rate of water in the flesh results in a significant reduction in molding time. Furthermore, since forced dewatering is performed through the drainage channels 5a and 5b, there is no need to dry the filtering material layers 3a and 3b every time molding is completed. Therefore, not only the device can be used repeatedly, but also the time required for repeated use can be shortened.
しかしながら先願に係る前記排泥鋳込み装置１

However, the sludge casting device 1 according to the earlier application
However, the number of times that it can be used repeatedly is said to be limited to about 500 times. The reason is that when the number of times of use exceeds that, the filtering material layers 3a, 3 made of gypsum etc.
This is because there is a risk that b may wear out and adversely affect the product shape. Therefore, conventionally, approximately
It was necessary to replace the filtering material layers 3a and 3b of the casting device 1 every time 500 products were molded.

とにより、上側の濾過材層３ａが成形される。 By the way, in the casting device 1, the drainage channels 5a and 5b must be buried inside the filtering material layers 3a and 3b. The procedure for this burying work will be explained using FIG. 7 as follows. Note that FIG. 7 shows the arrangement of the upper drainage channel 5a. First, a product model that is larger than the upper half of the molding space 4 by a predetermined thickness is prepared, and a wire mesh 9 is stretched over the surface of the model. Next, drainage channels 5a are attached to the surface of the wire mesh at predetermined pitches. Similarly, another wire mesh with a lower drainage channel 5b attached thereto is prepared. Next, the wire mesh equipped with the lower drain channel 5b is placed in a predetermined position of the lower pressure container 2b, and then a model having the same shape and size as the product to be manufactured is placed thereon. . Then, gypsum is poured between the pressure container 2b and the model and is hardened to obtain the lower filtering material layer 3b. Subsequently, the wire mesh 9 equipped with the upper drainage channel 5a and the upper pressure-resistant container 2a are placed on the lower pressure-resistant container 2b, and then gypsum is poured into the inside to form the upper filtering material layer 3a. Ru.

所期の肉厚が得られず、泥漿鋳込み製品にとつて
致命的な欠陥となるからである。 As described above, the conventional burying work of drainage channels 5a and 5b was complicated and required a very large number of steps. In addition, considerable precision is required for the buried position. This is because the deposition rate of the slurry and the diffusion rate of water in the filter media layers 3a and 3b are as follows:
Since it is greatly influenced by the distance from the inner surface of the filter material layers 3a, 3b, which is the molding surface, to the drainage channels 5a, 5b, if the positions of the drainage channels 5a, 5b are not accurate,
This is because the desired wall thickness cannot be obtained, which is a fatal defect for slurry-cast products.

つた。 In short, in the conventional sludge casting device 1, the work of replacing or changing the filtering material layers 3a and 3b not only involves a large number of steps and is complicated, but also
Since high accuracy is required in the arrangement of a and 5b, it is extremely inefficient to perform this every time 500 products are manufactured, and the cost is high.

In order to eliminate the above-mentioned drawbacks, the present invention is an improvement of the sludge casting device previously filed by the present applicant, and its features include a pressure-resistant container that can be divided into upper and lower parts, and a pressure-resistant container that can be divided into upper and lower parts. It has a three-layer structure consisting of an upper and lower synthetic resin layer formed on the inner surface of each of the pressure-resistant containers, and an upper and lower filtering material layer made of gypsum or the like formed on the inner surface of each of the upper and lower synthetic resin layers, Drainage pipes are embedded at appropriate pitches inside each of the upper and lower synthetic resin layers, and each of the drainage pipes has at least one end communicating with the outside of the pressure container, and has a drainage hole in a portion facing the filtering material layer. The holes are bored at appropriate intervals, and a water-permeable member is interposed between the drainage holes of the drainage pipe and the filtering material layer.

In the slurry casting device having the above configuration, when the slurry supplied to the molding space formed inside the filter layer is pressurized and at the same time the drain pipe is connected to the atmosphere or a negative pressure source, the inner surface of the filter layer is The water in the thickened slurry oozes out from the filter layer, through the water-permeable member, and into the drain pipe from the drain hole. As a result, the slurry rapidly adheres to the filter material layer, and the diffusion of water from the deposited portion to the filter material layer is promoted. This results in an increase in molding speed.

水管は、半永久的に使用することが可能である。 The filtering material layer of the sludge casting device according to the present invention can also be used repeatedly in the same way as the conventional one,
It must be replaced when a predetermined number of moldings is reached or when wear occurs. In the present invention, the filter material layer and the drain pipe are separated,
The drain pipe is embedded in a synthetic resin layer. Therefore, it is only necessary to replace the filtering material layer, and there is no need to make any changes to the buried state and arrangement of the drain pipe at this time. Therefore, the drain pipe buried in the synthetic resin layer can be used semi-permanently.

ない。 To replace the filter layer, for example, after removing the worn filter layer, a product model is installed at a predetermined distance from the inner surface of the synthetic resin layer, and the space between the synthetic resin layer and the product model is replaced. This is done by pouring a filter material such as gypsum into the container and allowing it to harden. At this time, the water-permeable member attached to each drain hole of the drain pipe prevents the poured filter material such as gypsum from flowing into the drain pipe and clogging the drain pipe. After the filtering material has hardened, the water-permeable member does not prevent water from moving from the filtering material layer to the drainage layer.

According to the sludge casting device according to the present invention, only the worn filter layer can be replaced without making any changes to the arrangement and buried state of the drain pipe buried in the synthetic resin layer. Further, the drain pipe need only be buried when the casting device is manufactured. Therefore, the work of burying the drain pipe, which is extremely difficult due to the large number of steps, is complicated, and requires high precision, is omitted, so that the work of replacing the filter medium layer becomes extremely simple and takes a short time. The result is a significant increase in productivity and a significant reduction in costs. Furthermore, since the mold setup can be changed simply by changing the filtering material layer, it is easy to change the design in response to customer requests.
