Description

Technical Field

[0001] The invention relates to the technical field of molding, in particular to a concrete tile pressing and molding die. Background Art

[0002] Concrete tiles can restore the texture, color and natural texture of cement. The laying effect is simple and the texture is light, which can be applied to many decoration styles. The traditional concrete tile forming mold is to inject the slurry into the forming mold and then solidify it by heating and drying for a long time. In order to prevent the slurry from deforming, the forming mold needs to support the slurry and heat and dry it together until the brick is formed and solidified. Multiple forming molds are required during production. In addition, the water in the slurry is not precipitated, which makes the heating and curing time-consuming and energy-intensive, and the finished brick has low density and poor performance. Summary of the invention

[0003] The object of the present invention is to provide a concrete tile pressing mold to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] A concrete tile pressing and forming mold,

[0006] Upper molded plate;

[0007] A lower die pad, the lower die pad is arranged below the upper die pressing plate, the lower die pad and the upper die pressing plate are parallel to each other, and a plurality of water-repellent holes are arranged in the middle of the upper die pressing plate and the lower die pad;

[0008] A molding frame, the molding frame is fixedly mounted on the upper side of the lower mold pad, and the molding frame includes:

[0009] A bottom plate, wherein a plurality of drainage holes are provided in the middle of the bottom plate;

[0010] An elastic rubber strip, which is fixedly mounted on the upper side of the bottom plate and is connected end to end along the edge of the bottom plate;

[0011] A pressure-resistant crawler is arranged on the upper side of the elastic rubber strip, and the pressure-resistant crawler covers the elastic rubber strip and is fixedly connected to the bottom plate.

[0012] The beneficial effects of the present invention are as follows: a forming frame is formed by the elastic rubber strip and the pressure-resistant track on the bottom plate, and the concrete slurry in the forming frame is pressed by the upper mold plate and the lower mold pad, so that the moisture in the slurry can be squeezed out from the drainage holes and the hydrophobic holes, so that the slurry can be pressed into a blank, which greatly saves the time and heat energy consumption for subsequent drying and curing; the slurry can be confined in the forming frame by the elastic rubber strip, and can also adapt to the change of the pressing spacing during extrusion; the pressure-resistant track can separate the elastic rubber strip from the slurry, so that the slurry can be formed in the forming frame while avoiding the elastic rubber strip from contacting the slurry, thereby extending the service life of the elastic rubber strip.

[0013] As a further improvement of the above technical solution, the upper mold plate, the lower mold pad and the bottom plate are all rectangular plates, and there are four elastic rubber strips, which are respectively arranged along the four sides of the bottom plate. Through the above technical solution, the elastic rubber strips can be surrounded by a rectangle, so that the tiles can be formed into a rectangular plate, which is convenient for laying over a large area.

[0014] As a further improvement of the above technical solution, the pressure-resistant track is in the shape of a long strip, and there are four pressure-resistant tracks, and the four pressure-resistant tracks cover the four elastic rubber strips respectively, and the ends of the four pressure-resistant tracks are stacked on each other. Through the above technical solution, the elastic rubber strip is covered by the pressure-resistant track to prevent the elastic rubber strip from directly contacting the slurry and affecting the service life of the elastic rubber strip; and the slurry can be surrounded in the molding frame for pressing.

[0015] As a further improvement of the above technical solution, the cross section of the elastic rubber strip perpendicular to its length direction is narrow at the top and wide at the bottom, and the side of the elastic rubber strip close to the middle of the forming frame is an inclined surface. Through the above technical solution, the upper part of the elastic rubber strip is narrower, so that the elastic rubber strip is easier to be flattened and deformed, and the lower part of the elastic rubber strip is wider, and the side close to the middle of the forming frame is an inclined surface, which is convenient for demolding the pressed blank.

[0016] As a further improvement of the above technical solution, the cross section of the elastic rubber strip perpendicular to its length direction is triangular, polygonal or trapezoidal, and its width changes linearly from top to bottom. Through the above technical solution, the pressing distance can be changed by adjusting the pressing force of the upper mold pressing plate and the lower mold pad, and the width of the elastic rubber strip changes linearly from top to bottom, which is convenient for adjusting the pressing distance.

[0017] As a further improvement of the above technical solution, a drainage filter is fixedly provided between the molding frame and the lower mold pad and on the lower side of the upper mold pressing plate. Through the above technical solution, the water in the slurry can also seep out from the drainage filter, and the drainage filter can also limit the slurry in the molding frame to prevent the slurry from being squeezed out from the drainage holes of the bottom plate and the hydrophobic holes of the upper mold pressing plate.

[0018] As a further improvement of the above technical solution, a water-absorbing felt is further provided between the upper mold plate and the drainage filter. Through the above technical solution, the felt is elastic, has good bonding and filtering properties, and is wear-resistant and pressure-resistant, and is very suitable for waterproofing, sealing or gasketing of the upper mold plate. When pressed, the water in the slurry can seep out and be filtered from the felt.

[0019] As a further improvement of the above technical solution, the water-repellent holes are evenly arranged and distributed in the middle of the upper die plate and the lower die pad, and the drainage holes are evenly arranged and distributed in the middle of the bottom plate. Through the above technical solution, the water-repellent holes and the drainage holes are evenly distributed, which facilitates the uniform extrusion of the moisture of the blank in the forming frame, avoiding forming differences in different parts of the blank.

[0020] As a further improvement of the above technical solution, a demoulding filter is laid on the upper side of the forming frame, and the demoulding filter completely covers the multiple drainage holes on the bottom plate. Through the above technical solution, after the slurry is pressed and formed in the forming frame, the demoulding filter makes it easier for the formed blank to be separated from the forming frame through the demoulding filter, thereby avoiding deformation and distortion of the blank.

[0030] Reference Figures 1 to 3 The concrete tile pressing and forming mold of the present invention is made into the following embodiments:

[0031] A concrete tile pressing mold comprises an upper mold plate 100 , a lower mold pad 200 and a molding frame 300 .

[0032] The upper mold plate 100 and the lower mold pad 200 are both rectangular plates, and a plurality of evenly arranged and distributed hydrophobic holes 110 are provided in the middle of the upper mold plate 100 and the lower mold pad 200. The lower mold pad 200 is arranged below the upper mold plate 100, and the lower mold pad 200 and the upper mold plate 100 are parallel to each other. A drainage filter 400 is fixedly provided on the lower side of the upper mold plate 100, and a water-absorbing felt 500 is also provided between the upper mold plate 100 and the drainage filter 400.

[0033] The molding frame 300 is fixedly mounted on the upper side of the lower mold pad 200, and a drainage filter 400 is also fixedly arranged between the molding frame 300 and the lower mold pad 200. The molding frame 300 includes: a bottom plate 310, an elastic rubber strip 320, a pressure-resistant track 330 and a demoulding filter 600.

[0034] The bottom plate 310 is in the shape of a rectangular plate, and a plurality of evenly arranged drainage holes 311 are provided in the middle of the bottom plate 310. A demoulding filter 600 is laid on the upper side of the molding frame 300, and the demoulding filter 600 completely covers the plurality of drainage holes 311 on the bottom plate 310. The elastic rubber strip 320 is fixedly installed on the upper side of the bottom plate 310, and there are four elastic rubber strips 320, and the four elastic rubber strips 320 are respectively arranged end to end along the four edges of the bottom plate 310.

[0035] The pressure-resistant track 330 is arranged on the upper side of the elastic rubber strip 320 . The pressure-resistant track 330 is in the shape of a long strip. There are four pressure-resistant tracks 330 . The four pressure-resistant tracks 330 cover the four elastic rubber strips 320 respectively. The ends of the four pressure-resistant tracks 330 are stacked on each other. The pressure-resistant track 330 is fixedly connected to the base plate 310 .

[0036] Reference Figures 1 to 3 When using the concrete tile pressing mold of the present invention: first, inject concrete slurry into the molding frame 300, and then press the upper mold plate 100 and the lower mold pad 200 together. The lower mold pad 200 flattens the elastic rubber strip 320, so that the water of the slurry in the molding frame 300 is squeezed out. The squeezed water seeps out and flows away from the drainage hole 311, the hydrophobic holes 110 of the upper mold plate 100 and the lower mold pad 200, the drainage filter 400 and the water-absorbing felt 500, so that the water of the slurry is squeezed out and compressed in the molding frame 300.

Figure 3 The cross section of the elastic rubber strip 320 perpendicular to its length direction is triangular, polygonal or trapezoidal (a is a triangular cross section, b is a polygonal cross section, and c is a trapezoidal cross section), and its width changes linearly from top to bottom, so that the pressing distance can be adjusted by adjusting the pressing force between the upper mold pressing plate 100 and the lower mold pad 200. The specific size and shape of the elastic rubber strip 320 can be selected according to the actual situation based on the height requirements of the molding frame 300 and the compression requirements.

[0038] The shape of the bottom plate 310 can be selected into various shapes such as a triangular plate or a polygonal plate. The shape of the bottom plate 310 can be selected according to the molding requirements of the concrete tiles.
