Definitions

  • the invention relates to a process for the serial processing of an inorganic and / or organic material, which contains a liquid content of between 3 and 90% by weight, into a molding by means of core casting and / or hollow casting, the material being located in at least two porous moldings Cavity is introduced and dehumidified in contact with the adjacent moldings.
  • the invention further relates to a device for performing this method.
  • the plaster molds commonly used in the manufacture of tableware and sanitary ware are known to have the disadvantage that on the one hand they can only be used for a limited number of castings, while on the other hand the filtration process, i.e. the consolidation of the body by dehydration requires a great deal of time and therefore also cost. It is generally assumed today that the formation of a body with a thickness of 10 to 11 mm takes about 1 1/4 hours and that after a further hour the body is released from the plaster mold by the shrinkage. If the usual plaster molds are used, the next casting can only take place after a time-consuming and energy-consuming drying or dewatering process. Such waiting times are of course a considerable obstacle in mass production (see. Handbook of Ceramics, Verlag Schmid GmbH, 1970, page 9).
  • One of the problems that has so far remained unsolved, for example, is to specifically control the moisture distribution that necessarily fluctuates within the porous shape during the entire manufacturing process in such a way that not only is the water removed from the slurry introduced, as uniformly and quickly as possible, but that the shape in the border area of the body still has enough water for problem-free removal of the body and this "release water” does not remain in the porous molding material at the moment of removal, but emerges in the above-mentioned limit area and thus forms an ideal release pad. It is important here that the release water mentioned is not only available in the form of a thin film of moisture, but that a plentiful, even water cushion is available on all sides.
  • the object of the present invention to propose a method and a device for the series production of moldings, in particular dishes and sanitary ware, which allows the aforementioned disadvantages to be remedied.
  • the method according to the invention is accordingly based in particular on the task, using porous plastic molds, to control the liquid distribution fluctuating within the molds in the course of the manufacturing process in a targeted manner and in dependence on the respective production phase in such a way that not only is there a significant reduction in the filtration process, but also an optimal one Detachment of the body results.
  • the aim is to solidify the damp body while, to a certain extent, the reusability of the backcasting or hollow casting slip results as a secondary effect without any control or cleaning.
  • the moldings are said to be able to withstand the strength requirements set in the company.
  • the device has two mutually opposite molded bodies la and lb, which consist of a porous plastic and are shaped on their mutually facing surfaces so that they are one in the retracted state (see FIG. 4) for receiving the slip and Limit the formation of the ceramic body serving cavity shape F.
  • Both molded bodies la / lb are provided with parallel bores 2 which protrude inwards from the rear end face of each molded body and end shortly before the front end faces Sa / Sb. It is therefore blind holes that can be fed in each molded body through a common network of channels 3a, 3b.
  • the channels 3a / 3b are worked into the surface of pressure plates 4a / 4b, which are provided with an inlet and outlet channel 5a / 5b.
  • the pressure plates 4a / 4b which are preferably made of metal, for example aluminum, have a grid of channels 3a / 3b on their end faces facing the shaped bodies (see FIG. 2) and are fastened to the shaped bodies by means of screws 6.
  • a drive device for example a corresponding hydraulic energy store
  • the two pressure plates 4a / 4b can be moved against one another for the purpose of closing the mold and can be kept under pressure for the final sealing of the interface between the moldings.
  • piston rods 7, which rest with end flanges 8 on the respective pressure plates 4a / 4b, are used for power transmission.
  • the two-part form according to FIG. 1 is open. Both molded bodies la / lb are connected to a vacuum source via the duct networks 3a / 3b.
  • the over the grid system of the press plate (Fig. 2) on the channels 3a / 3b continuing negative pressure exerts a suction effect thanks to the porosity of the moldings, which extends practically into the end faces Sa / Sb. This results in a careful drainage of the free surfaces of the moldings, which can be controlled in a targeted manner by means of the negative pressure.
  • the slip which forms the prepared starting material of the manufacturing process can consist of an inorganic and / or organic material with a liquid content between 3 and 90% by weight.
  • the grain spectrum of the solid basic substance can be within wide limits, i.e. are between 0.5 p and 5 mm.
  • the casting slip In the first phase of the mold filling, the casting slip is used to avoid turbulence under low pressure, i.e. at about 0.1 to 3 bar.
  • the inflowing slip mass displaces the volume air of the casting, which escapes through an appropriately arranged opening (hollow casting opening).
  • the pressure on the tableware slip in the mold is hydraulic, for example with the aid of membranes.
  • FIG. 1 shows two channels 9 and 10, which are provided with shut-off valves 11 and 12, open into the hollow mold F.
  • the filling valve 12 When filling and then pressurizing the slip, the filling valve 12 is opened, the emptying valve 11, on the other hand, is closed.
  • the air contained in the cavity 5 escapes through the porous shape and the channel system.
  • the channels 3a, 3b, 5a, 5b are open.
  • the channels are le 3a / 3b / 5a / 5b thus vented.
  • This back pressure which is applied from the outside, can have the task, inter alia, of keeping the water which has entered the moldings from the slip within the moldings, so that it is still available during the final detachment process.
  • the formation of the uniform water cushion which is absolutely necessary for a problem-free detachment process and which is not interrupted (e.g. due to larger air pockets) can take place completely independently of any counter pressure exerted on the channel system of the mold.
  • the moisture absorption and distribution in the mold are thus not controlled by any kind of back pressure in this phase, but are exclusively a function of the pressure from the slip side and the very special properties of the microporous structure and the structure of the mold, i.e. Sealing to the outside, formation of the sealing surface D etc.
  • the slip mass solidifies as a result of the removal of water, and the shaped body of the ceramic shards shown in FIG. 5 and designated 13 is formed on the end faces Sa / Sb.
  • the valve 11 is opened and the residual or cavity slip runs off. This emptying process can be supported by compressed air, which can be introduced through the valve 12.
  • a pneumatic pressure is built up within the cavity H after the back or cavity slip has expired and is held for a certain period of time which is dependent on the molding and slip material. For example, when manufacturing a ceramic vanity, a pneumatic pressure of 15 bar was maintained for 10 to 15 seconds. This prevents the run-on, with part of the water in on the walls of the formed product penetrates the molding.
  • the cullet treated in this way with compressed air accordingly has a drier inner surface and is demonstrably more solidified than a non-pressure-treated ceramic part, which can be of crucial importance in particular in hollow casting.
  • the process of pneumatic pressure application can be repeated several times, whereby the remaining slip material that has meanwhile gathered can be drained by temporarily opening the drain valve.
  • the application of a pneumatic pressure in the cavity H thus serves to prevent overrun and to achieve increased strength of the molding.
  • the filtrate extracted from the slurry during the formation of the cullet penetrates into the boundary layer of the shaped body adjacent to the cullet, where it forms the coherent water cushion which is essential for the detachment process. It is imperative to prevent air from passing through the cullet during the cohesion hardening process that is too long or too strong and to displace or interrupt the interrelated water cushion (false air) and therefore the problematic detachment of the cullet from the mold surface is no longer guaranteed.
  • the moisture distribution within the moldings can be additionally controlled by a balanced coordination of the air pressure applied in the cavity H and a pneumatic or hydraulic counter pressure applied from the outside via the channels 5a / 5b.
  • a vacuum is first applied to the one molded body 1b via the channel 5b, while a pneumatic release pressure acts on the molded body 1a via the channel 5a.
  • a pneumatic release pressure acts on the molded body 1a via the channel 5a.
  • the body 13 is pressed out of the shaped body 1 a and held in place by the shaped body 1 b by vacuum. The process taking place here is best seen in FIG. 3.
  • FIG. 3 shows, on the basis of a simplified sectional illustration, two molded bodies 14 and 15 consisting of porous plastic, which in turn are clamped between two plates 4a / 4b.
  • the plates are anchored in the moldings by screws 18.
  • the cavity H enclosed by the two molded bodies 14 and 15 serves to form a hollow casting which is ready for the detachment process in the phase shown. Accordingly, part of the filtration water was displaced into the adjacent area W of the shaped bodies by the slip pressure, the capillary action of the porous material and the pneumatic pressure applied in the cavity H.
  • W in FIG. 3 thus designates a water cushion that completely encompasses the fragments. Of course, this cushion of water must not escape through channels 2 to the outside. This is ensured by keeping the water in the cullet / mold surface border area by preventing air from entering.
  • a pneumatic pressure can be exerted on the cavity H on the one hand, and on the outside on the molded body on the other.
  • a hydraulic or pneumatic back pressure is applied via channels 2.
  • the body 13 is then detached from the remaining molded body 1b (FIG. 6) or 15 (FIG. 3).
  • the locking or contact pressure in the limit area D must not be significantly above the sum of these elastic restoring pressures. If one designates the elastic restoring force of the molded body with FF, that of the ceramic body with FK, the slip pressure with FS, the following applies for the locking pressure FZ: the factor h, which ensures tightness in the border area D, should be between 1.05 and 1.2.
  • the pressure reduction during the opening process is adapted to the special needs of the molded part, i.e. the pressure reduction is slow in all cases, the opening process also takes place slowly and in phases in the case of moldings consisting largely of hollow castings, but takes place rapidly for moldings largely consisting of core casting.
  • FIG. 7 shows the opening speed v, ie the speed at which the two sealing surfaces Sa and Sb move apart during the opening process, as a function of the time for molded articles which are largely produced using the hollow casting process.
  • v the opening speed at which the two sealing surfaces Sa and Sb move apart during the opening process
  • the method described is characterized by the possibility of uniform moisture distribution, a perfectly manageable detaching process, and a body that is noticeably more solid than the prior art.
  • Considerable time savings result from the fact that the slip is briefly kept under pressure after filling.
  • the slurry itself may only be filled with an initial pressure between 0.1 and 3 bar, otherwise turbulence may occur. Only afterwards, i.e. after at least a large part of the slip material has been introduced, the pressure can be increased to a multiple, for example to 10 to 50 bar.
  • moldings made from warm material e.g. slurry at 40 ° C
  • warm material e.g. slurry at 40 ° C
  • the shaped body denoted by lb in FIG. 1 has, as mentioned, an annular sealing surface D and a projection delimited by the end surface Sb (casting surface). These two surfaces D and Sb are loaded at the same time on the one hand and on the other hand with different pressures when carrying out the die-casting method described.
  • the one made of porous plastic Molds, as tests have shown, cannot withstand this alternating stress in the long run. At the transition from the sealing surface D to the casting surface Sb, fine cracks soon appear under the influence of the notch effects that occur, which cause the molded body to break when it is used again.
  • the shaped bodies 1 a and 1 b are preferably provided with a reinforcement which takes into account the special structure of the shaped bodies and their material.
  • a reinforcement which takes into account the special structure of the shaped bodies and their material.
  • the porous plastic mass which has the main function of water absorption, is designated by K in FIGS. 8 and 9.
  • This plastic mass K is penetrated by a coherent reinforcing grid A, which is guided around the holes 2 at a distance around them and also extends over a depth that corresponds to that of the holes 2.
  • the lattice structure of the reinforcing lattice A thus encompasses all of the bores 2 over their entire length (FIG. 9) and gives the molded body considerable strength against the pressure loads that occur.
  • the reinforcing material A penetrates the spaces between in the embodiment shown the individual holes 2 completely and thus forms a network of intersecting stiffening walls.
  • the reinforcement grid A consists of the same plastic that forms the water-absorbing mass K, with the difference, however, that pore-forming substances were not added to this plastic during its production. This ensures that the base material K and the reinforcement A connect perfectly to one another, while on the other hand there is a considerable increase in strength due to the elimination of the pores.
  • the structure of the reinforcing mesh A in the variant shown is interspersed with metallic wire meshes G, three wire meshes D being arranged one above the other at a distance from one another.
  • the division of the grids D corresponds exactly to the arrangement of the reinforcement grille A shown in FIG. 8.
  • recesses are drilled or milled out on the cast molded body la or lb (as in FIG. 1), which are then poured out with the reinforcing material after the bores 2 have been closed by plugs. In principle, however, it is also possible to leave the recesses required for the reinforcement free at the first casting and then to pour them out.
  • the base material of the shaped bodies 1a, 1b is a wear-resistant plastic, to which a pore-forming substance is added during its manufacture, so that the desired porous structure is obtained.
