Abstract
The utility model provides a slury-filling die for ceramic body forming, which is structurally characterized in that the traditional ceramic body slury-filling die (a male mould and a female mould are composed) is made into a column shape, the radial outer surface of the column is a layer of sheet metal with a 1-5 mm thickness. The male mould and the female mould are respectively arranged with a special aeration pipe for die unwrapping which is not communicated with a die cavity. As the round die with a metal shell can undergo a larger slury-filling pressure (more than 0.3 MPa), the water content and the gas after filling the slury can be discharged rapidly, the body drying velocity is fast, the density is high, the distortion is tiny after baking. Besides, due to the special aeration pipe for die unwrapping is arranged, the unwrapping speed is fast, the work intensity is low, the appearance and the quality of the product are good, which can not only improve the production efficiency, but also improve the quality of the product.
Description
Technical field
The utility model relates to a kind of slip casting mould that is used for the ceramic body moulding, relates in particular to a kind of grouting pressure up to more than the 0.3MPa, and the slip casting mould that can carry out the demoulding within a short period of time.
Background technology
The known slip casting mould that is used for the ceramic body moulding, as shown in Figure 1, 2, constitute by punch 1, die 5, the die body material is a gypsum, the Grouting Pipe 3 and the purge tube 4 that connect die cavity are arranged on the die, grouting pressure is generally less than 0.11MPa, because the pressure during slip casting is low, the density of goods is low, burns till back deformation rate height, simultaneously, because pressure is low, moisture content can only lean on gypsum to absorb naturally, so will look the thickness size and the concentration of hydraulic mixture of base substrate after slip casting finishes, at least leave standstill 15 minutes (thin smallclothes) to 6 hours (thick big) but after the just demoulding, influenced its production efficiency.
Summary of the invention
The purpose of this utility model is will provide a kind of can bear higher grouting pressure (more than the 0.3MPa) and (thin smallclothes do not surpass 5 minutes, and thick big does not surpass 60 minutes) demoulding in the short period of time, and the extrudate density height burns till the little slip casting mould of back deformation rate.
The utility model is achieved by following technical proposals: the utility model with die body cast in one highly identical, not with cover up and down, the side has in the round metal cylinder of grouting port and blow vent, respectively sets up a breather pipe that does not communicate with die cavity simultaneously on punch and die.
The utility model slip casting mould has following useful effect compared with prior art:
1, because plaster mold is changed into roundly by square, and be cast in the metal cylinder, so can bear higher pressure (more than the 0.3MPa) during slip casting, the ceramic body density of producing is higher, and it is little to burn till the back deformation rate:
Pressure height during 2, owing to slip casting, moisture content in porcelain (pottery) mud and the air in the die cavity can be pressed into die body by the micropore of gypsum, and discharge the crack between two adjacent molds, have improved the rate of drying of base substrate, have shortened and have opened the preceding time of repose of mould.
3, because each all is provided with the breather pipe of using for die sinking on punch and die, when successively to die, punch feeding compressed air, die, punch break away from base substrate automatically, have improved stripping rate and presentation quality, have alleviated the labour intensity of the demoulding.

The specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is further described, so that more clearly understand the utility model.
Referring to Fig. 1-5, a kind of slip casting mould that is used for the ceramic body moulding, constitute by die 16, punch 11, die, punch all cast in wall thickness 1-5 millimeter by gypsum, in highly identical with the mould circular metal tube, stud with left-right symmetry on the metal barrel, the slide block 6,7 that is used for supporting mould, have for Qi Moyong the round vent that matches with breather pipe 10,15 respectively, and the circular injected hole that matches with Grouting Pipe 13 simultaneously.
(see figure 5) is successively with punch 19 when making ceramic body, die 20, punch 21, die 22 ... be contained in two guide rails 16 of slip casting machine etc. some pairs of moulds, between 17, and utilize two guide rails and top board 18 that mould is fixed up, the pressure of usefulness 〉=0.3MPa injects mud by Grouting Pipe 13 then, air in the mud and moisture content are then discharged (at this moment by the crack between punch and the die, purge tube 14 is pushed down by top board 18 or adjacent punch, mud can not overflow from purge tube), slip casting finishes, and leaves standstill 5 to 60 minutes, start the slip casting machine oil pump, allow oil cylinder connecting rod 15 drive top board 18 and leave mould, successively to the breather pipe 15 of die, breather pipe 10 input pressures of punch are the above compressed air of 0.1MPa then, make die and punch successively leave ceramic body, entire making process is finished.
Experiment showed, that the ceramic body extrudate density of producing with the utility model is big, deformation rate is little after burning till, and molding time is short, and product defect is few, thereby has improved the quality and the production efficiency of product greatly.
Claims (2)
1, a kind of slip casting mould that is used for the ceramic body moulding, be a kind of ceramic body process units, it is made of a die and a punch, it is characterized in that: the profile of die and punch all is a cylinder, cylinder the inside material is a gypsum, radially-outer surface is the sheet metal of a layer thickness at the 1-5 millimeter, and the Y-axis of die body respectively studs with a slide block that is used for supporting mould to two ends.
2, slip casting mould according to claim 1 is characterized in that: in described die and the punch, all be provided with one for the breather pipe that does not communicate with die cavity that opens that mould uses.
