Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a backing plate for placing a molding base immediately after being demolded from a slurry casting mold.

[0002]

[Prior Art]

 When manufacturing sanitary ware such as toilet bowls and handwashers, the molding base is obtained by the slurry casting method. In the slurry casting method, the slurry is injected into the casting space of the molding die, and the surface of the molding die absorbs the water in the slurry to inject the solid component. Then, when the inking reaches a predetermined thickness, excess sludge is discharged and demolded to obtain a molding substrate. Immediately after demolding, the molding base is soft and contains a lot of water, and therefore easily plastically deforms. Therefore, in the past, the molding substrate immediately after demolding was once placed on a receiving plate made of a veneer plate to drain the surface of the molding substrate and prevent deformation.

[0003]

[Problems to be solved by the device]

 By the way, when the mold base is released from the mold, the water retained in the mold is forced to exude between the mold surface and the mold base to improve slippage and facilitate the mold release. There is. However, this exuded water collects between the upper surface of the backing plate and the bottom surface of the molding base when the molding base immediately after demolding is placed on the backing plate. For this reason, conventionally, there have been drawbacks such as a difference in water content between the inner and outer surfaces of the bottom of the forming body, the forming body adhering to the receiving plate, and the forming body deforming when separated from the receiving plate.

In order to solve the above-mentioned drawbacks, an object of the present invention is to provide a backing plate that does not collect water between the top surface of the backing plate and the bottom surface of the molding base.

[0005]

[Means for Solving the Problems]

 The first means adopted by the present invention is a sludge casting characterized in that the receiving plate for receiving the sludge casting molding base is made of a porous material having water permeability and the average pore diameter is 50 μm or more. It is a backing plate for molding base. The second means adopted by the present invention is a slurry casting molding base plate in which the porous material in the first means is a multi-hole plate. A third means adopted by the present invention is a slurry casting mold base plate in which the base plate of the first or second means is housed in a pan.

[0006]

[Action]

 The water-passing action of the backing plate retains or allows the dropped water to pass therethrough, so that it does not collect water between the backing plate and the bottom of the placed molding base. When the backing plate is stored in the pan, the water that has passed through the backing plate is collected by the pan so that the water does not scatter.

【Example】

 Hereinafter, a backing plate for a slurry casting molding base material according to the present invention (hereinafter referred to as a “backing plate of the present invention”) will be described based on an embodiment shown in the drawings. (1st Example) FIG. 1: is sectional drawing which shows 1st Example of the receiving plate of this invention. The receiving plate 1 of the present invention is a plate-shaped member made of a porous material having water permeability. The average pore size of the porous material is 50 μm or more, preferably about 100 μm. As the porous material, an aggregate such as sand is hardened with an epoxy resin or the like to form pores between the aggregates, or a bead-shaped resin ball is heat-sealed and solidified between the resin balls. Those having pores formed therein, or those obtained by adding water to an epoxy resin to emulsify it and curing it, and then forcibly drying water to make it porous, etc. are appropriately selected.

The present invention support plate 1 is housed in a saucer 2, and an appropriate number of rod-shaped dustants 3 are interposed between the bottom surface 2 a of the saucer 2 and the present invention support plate 1. The tray 2 is provided with a drain cock (not shown) at an appropriate place so that the accumulated water can be discharged.

As described above, since the receiving plate 1 of the present invention is formed of a multi-perforated plate having an average hole diameter of 50 μm or more and having water permeability, it is dropped when the molding substrate 4 after demolding is placed. Since the water for demolding is retained or passed through, it does not accumulate with the bottom surface 4a of the molding base 4. Furthermore, when the receiving plate 1 of the present invention is stored in the receiving plate 2, the water that has passed through the receiving plate 1 is collected by the receiving plate 2, so that the water will not be scattered around the molding device or the like.

(Second Embodiment) FIG. 2 is a sectional view showing a second embodiment of the receiving plate of the present invention. The support plate 11 of the present invention is one in which the surface of a perforated plate 15 having water permeability is covered with a cloth 16. The perforated plate 15 is made of a stainless steel plate, a synthetic resin plate or the like perforated by a press or the like, and the hole diameter of the hole 15a is about 1 to 15 mmφ (preferably 10 mmφ). The cloth 16 is for preventing the traces of the holes 15a of the perforated plate 15 from being transferred to the molding base 4 (see FIG. 1), and is a filter cloth having elasticity and water permeability.

The present invention receiving plate 11 is housed in the receiving tray 2, and an appropriate number of rod-shaped dustants 3 are interposed between the bottom surface 2 a of the receiving tray 2 and the present invention receiving plate 1. By joining the dust proof 3 to the back surface side of the multi-hole plate 15 in advance, it is possible to double the perforated plate 15.

The receiving plate 11 of the present invention allows the water for demolding that drops when the forming substrate (not shown) is placed on the upper surface 16a of the cloth 16 to pass through, so that the water between the bottom surface of the forming substrate and the water is removed. There is no accumulation. Further, when the receiving plate 1 of the present invention is stored in the receiving plate 2, the water that has passed through the receiving plate 1 is collected by the receiving plate 2, so that the water is not scattered around the molding device or the like.

Other Embodiments The plates 1 and 11 of the present invention can of course be used alone without being stored in the tray 2.

[0014]

[Effects of the Invention] As described in detail above, the present invention support plate is formed on the support plate by retaining or passing the dropped water so that water does not accumulate between the bottom surface of the molding base placed on the support plate. Does not adhere to the base material or deform the base material when it is separated from the backing plate. Therefore, the receiving plate of the present invention has a practical effect that can dramatically improve the yield of the forming material. In addition, since the receiving plate of the present invention collects the water that has passed through the receiving plate in the receiving plate when the receiving plate is stored in the receiving plate, it does not scatter water around the molding equipment, etc. and maintains a good working environment. can do.
