For achieving the above object, the technical solution of the utility model is: gypsum extrusion forming mold, comprise counterdie and patrix, described counterdie and patrix are tightly connected, a top board is provided with in described patrix, the shape of described top board is identical with size with the cross sectional shape of the inner chamber of patrix with counterdie with size, and described top board is fixed with the upperpush rod that is stretched out patrix, and described counterdie is provided with grouting port.
When adopting technique scheme, add a top board by traditional die cavity up and down, before gypsum slip casting, top board is pressed down, by grouting port, the air in die cavity can be discharged, prevent too many air residual from causing producing bubble in shaping gypsum.Moreover, after gypsum slip casting, can be extruded gypsum slurry by top board.Compare traditional gravitational coagulation, the better effects if of pressure condensation, can improve the compactness of gypsum, increases surface smoothness and the bulk strength of product.
Further improvement project, the inner bottom surface of described counterdie is provided with rough pattern.By the inner bottom surface of pattern setting at counterdie, change the principle of traditional pattern forming.Traditional pattern forming is the top being arranged on internal chamber wall, and the pressure acted on gypsum slurry is far smaller than the pressure in this programme, therefore, the deadweight of gypsum slurry and the pressure of top board can be made full use of in this programme, make shaping pattern effect better.
Further improvement project, the height bottom described grouting port distance counterdie is 1cm.
Further improvement project, the top of described patrix is fixed with connector.Connector is set, patrix can be moved up and down by connector, play the effect be fixedly connected with.
Further improvement project, described top board is provided with sealing ring.Top board arranges sealing ring and can increase sealing effectiveness between top board and upper and lower mould inwall, prevent gas leakage and spillage.
Further improvement project, the end face of described counterdie is provided with sealing ring.This setting can increase the sealing property between counterdie and patrix end face, prevents gas leakage and spillage between upper and lower mould.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model gypsum extrusion forming mold embodiment.
Reference numeral: counterdie 1, patrix 2, connector 21, top board 22, upperpush rod 23, grouting port 11.
Detailed description of the invention
As shown in Figure 1, the utility model gypsum extrusion forming mold, comprise counterdie 1 and patrix 2, counterdie 1 is fixedly installed, and patrix 2 is set on counterdie 1, is tightly connected between patrix 2 and counterdie 1.Wherein, the inner bottom surface of counterdie 1 is provided with rough pattern, by this setting, can form pattern and lines, play the effect of decoration on shaping plasterboard face.The upper surface of patrix 2 is fixed with two connectors 21, by connector 21, patrix 2 entirety can be taken off from counterdie 1.In addition, patrix 2 is also provided with a top board 22, the shape of top board 22 is identical with size with the cross sectional shape of the inner chamber of patrix 2 with counterdie 1 with size, and can slide along the internal chamber wall of counterdie 1 and patrix 2.Above top board 22, be fixed with a upperpush rod 23, top board can be operated by top board 23 and move up and down.In addition, the side of the close below of counterdie 1 has a grouting port 11, the inner space of grouting port 11 and counterdie 1.
During use, be placed on counterdie 1 by patrix 2 sealing, the mode of sealing can increase sealing joint strip in junction, utilizes connector 21 pairs of patrixes 2 to apply downward pressure, patrix 2 being pressed on counterdie 1, making patrix 2 and counterdie 1 can become the entirety of a sealing when injecting gypsum slurry.After having sealed, by operation upperpush rod 23, top board 22 is pressed into the bottom of counterdie 1, because the inwall of top board 22 and patrix 2 and counterdie 1 is fitted, form piston effect, air between top board 22 and counterdie 1 can be discharged from grouting port 11, if actual production exists the problem of gas leakage or spillage, sealing ring can be increased in the side of top board 22.After above-mentioned work completes, in counterdie 1, gypsum slurry is injected by grouting port 11, while injection, slowly pull upperpush rod 23, progressively move up along with gypsum slurry injects counterdie 1 top board 22, and the speed as far as possible keeping gypsum slurry to rise in counterdie 1 is identical with the speed that top board 22 moves up.After injection gypsum slurry reaches the volume of specifying, grouting port 11 is closed, by upperpush rod 23 extruding top board 22 downwards, by the effect of external force, by the gypsum slurry compacting in patrix 2 and counterdie 1, until solidify formation plastering.After plaster formulation, by pulling connector 21, patrix 2 is deviate from from counterdie 1, due to the limited height of counterdie 1, therefore, in general, plastering can be attached on patrix 2, then extrudes top board 22 by upperpush rod 23, plastering is deviate from from patrix 2, obtains the plastering of complete and smooth.If it, because special circumstances are attached on counterdie 1, directly can take out, can not damage plastering equally by plastering from counterdie 1.
