[0001] The invention relates to the technical field of anti-falling ceramic tiles, in particular to a pressing method and a pressing mould for anti-falling ceramic tiles. Background Art

[0002] Anti-falling tiles are a type of tiles. This technology is mainly used for wall tiles. It increases the contact area between tiles and cement mortar through special patterns and grooves on the back, thereby more securely fixing the tiles to the wall.

[0003] According to the publication (announcement) number CN111283851B, the publication (announcement) date is 2020-09-01, and a square mold for anti-falling ceramic tiles is disclosed, including a mold sleeve and a mold core. The mold sleeve is provided with at least four inclined holes, and the four inclined holes are arranged in a "mouth" shape, and the four inclined holes are symmetrically arranged in pairs, and the two symmetrical inclined holes are in an "eight" shape. A mold core is arranged corresponding to each inclined hole, and the mold core includes an embedded part and a forming part. The embedded part matches the inclined hole, and the forming part is arranged below the embedded part. The device arranges the mold core in the inclined grooves in the four directions set by the mold sleeve, so that the anti-falling grooves in four directions are formed during the pressing process of the ceramic tiles, which can provide anti-falling force in four directions and greatly enhance the anti-falling force of the anti-falling ceramic tiles; at the same time, an elastic part is arranged, so that demolding after the pressing process is very convenient; the sharp bottom angle of the forming part at the bottom of the mold core is rounded, and the sharp bottom angle in the pressed anti-falling groove is rounded, which effectively prevents cracks caused by sintering stress concentration.

[0049] Embodiment 2

[0050] like Figure 1-10 As shown, a method for pressing anti-falling tiles and a pressing mold are used to implement the anti-falling tile pressing method in the above scheme, characterized in that it includes a frame 2, on which the following are movably provided:

[0054] The mounting shell 1 moves upward to shrink the flange 124 into the mounting tube 122, and the upper plate 11 and the module set 123 are separated from the blank.

[0055] Specifically, a guide rod 111 is provided on the frame 2, and the mounting shell 1 is slidably installed on the guide rod 111. The mounting shell 1 moves downward by vibration (its principle is the same as that of a vibration brick making machine and is not repeated here). The lower mold 21 is installed on the frame 2 in a liftable manner. The lower mold 21 and the frame 2 form a chamber for accommodating ceramic tile raw materials. The upper plate 11 is combined with the module group 123 to form an upper mold that cooperates with the lower mold 21.

[0056] Furthermore, when the tile pressing work is performed, the raw material is first put into the lower mold 21 on the frame 2, and then the installation shell 1 is driven to move downward, and the installation shell 1 drives the upper plate 11 and the module group 123 to move downward, and the module group 123 first contacts the tile raw material, and the module group 123 cooperates with the lower mold 21 to initially extrude the raw material. After the initial extrusion is completed, the installation frame 13 separates the module group 123 from the installation shell 1, and the installation shell 1 continues to move downward with the upper plate 11, vibrating and pressing the raw material, so that the raw material can move to the flange 124 of the module group 123, and the upper plate 11 cooperates with the lower mold 21 to press the raw material into a blank, and then the installation shell 1 moves upward. , the flange 124 of the module group 123 is retracted into the installation tube 122, at which time the module group 123 can move upward with the installation shell 1 and the upper plate 11 and separate from the blank. At this time, a plurality of semi-enclosed cavities are left on the blank, and then the lower mold 21 moves upward to push the blank out of the frame 2, at which time the blank can be taken out, and the blank is made into a finished tile after firing, glazing and other processes; when the tile is in use, cement mortar is applied to the back of the tile, and the cement mortar will enter the semi-enclosed cavity on the tile, the cement mortar gradually solidifies in the cavity to form a wedge fixed in the tile, and cooperates with the cement mortar outside the cavity to fix the tile to the wall.

[0057] In the above technical solution, when the tile pressing work is carried out, the raw material is first put into the lower mold 21 on the frame 2, and then the installation shell 1 is driven to move downward, and the installation shell 1 drives the upper plate 11 and the module group 123 to move downward, and the module group 123 first contacts the tile raw material, and the module group 123 cooperates with the lower mold 21 to initially extrude the raw material. After the initial extrusion is completed, the installation frame 13 separates the module group 123 from the installation shell 1, and the installation shell 1 continues to move downward with the upper plate 11, vibrating and pressing the raw material, so that the raw material can move to the flange 124 of the module group 123, and the upper plate 11 cooperates with the lower mold 21 to The raw material is pressed into a blank, and then the mounting shell 1 is moved upward, and the flange 124 of the module group 123 is retracted into the mounting tube 122. At this time, the module group 123 can move upward with the mounting shell 1 and the upper plate 11 and separate from the blank. At this time, a plurality of semi-enclosed cavities are left on the blank, and the blank is made into a finished tile after firing, glazing and other processes. When the tile is in use, cement mortar is applied to the back of the tile, and the cement mortar will enter the semi-enclosed cavity on the tile. The cement mortar gradually solidifies in the cavity to form a wedge fixed in the tile, and cooperates with the cement mortar outside the cavity to fix the tile to the wall.

[0058] As a further embodiment of the present invention, a limiting ring 22 corresponding to the module set 123 and having a diameter larger than the flange 124 is provided on the lower mold 21 .

[0059] Specifically, during the downward movement of the module group 123, the module group 123 cooperates with the lower mold 21 to press part of the ceramic tile raw materials into a truncated cone shape. The limiting ring 22 limits the ceramic tile raw materials located below the module group 123 to prevent the bottom edge of the truncated cone from being crushed due to the movement of the raw materials, thereby ensuring the molding of the raw materials at the bottom of the module group 123.

[0061] Specifically, multiple limiting rings 22 connected together can cooperate with the module group 123 to fix the bottom ceramic tile material, thereby preventing the limiting rings 22 from being separated from the surrounding material due to lateral movement of the bottom material when the installation shell 1 vibrates and presses down with the upper plate 11, thereby preventing cracks from appearing around the limiting rings 22 in the pressed blank.

[0062] As another embodiment further provided by the present invention, the module group 123 includes a plurality of first modules 125 and a plurality of second modules 126 distributed in a circular array, and the first modules 125 and the second modules 126 are staggered, and a guide plate 127 is rotatably provided on the mounting cylinder 122, and the guide plate 127 rotates to move the first module 125 and the second module 126 in sequence.

[0063] Specifically, the mounting tube 122 is provided with a mounting plate 115 extending to the bottom of the module group 123, and the first module 125 and the second module 126 are both slidably installed on the mounting plate 115. The outer walls of the first module 125 and the second module 126 are both provided with protrusions, and multiple protrusions are connected to form a flange 124 on the module group 123.

[0065] As another embodiment further provided by the present invention, a first guide groove 128 adapted to the first module 125 and a second guide groove 129 adapted to the second module 126 are provided on the guide plate 127, the second guide groove 129 includes an arc portion 114 and a ring portion 113 coaxial with the guide plate 127, and the first guide groove 128 and the arc portion 114 have the same shape.

[0066] Specifically, both the first module 125 and the second module 126 are provided with cylindrical protrusions adapted to the guide grooves on the guide plate 127 .

[0067] Furthermore, during the rotation of the guide plate 127, the first guide groove 128 (the same as the arc portion 114) on the guide plate 127 pushes the protrusion on the first module 125, driving the first module 125 to move into the installation tube 122. At this time, the protrusion on the second module 126 moves along the ring portion 113, and the relative position of the second module 126 and the installation tube 122 remains unchanged. The guide plate 127 continues to rotate, and the protrusion on the second module 126 enters the arc portion 114 of the second guide groove 129. The arc portion 114 of the second guide groove 129 pushes the protrusion on the second module 126, thereby driving the second module 126 to move into the installation tube 122.

[0068] As another embodiment further provided by the present invention, the mounting frame 13 is provided with an insert block 131 for fixing it on the frame 2, and the mounting shell 1 moves downward so that the module group 123 cooperates with the lower mold 21 to extrude the raw material and the mounting frame 13 is separated from the mounting shell 1.

[0069] Specifically, during the downward movement of the installation shell 1, the module group 123 first contacts the raw materials on the lower mold 21, gradually shaping part of the raw materials, and then the module group 123 is separated from the installation shell 1 and fixed on the frame 2. The module group 123 cooperates with the lower mold 21 to fix the initially extruded raw materials. At this time, the installation shell 1 can continue to move downward, and the upper plate 11 on the installation shell 1 can continue to press other ceramic tile raw materials on the lower mold 21.

[0072] Furthermore, in the process of the installation shell 1 moving downward with the installation frame 13 and the module group 123, the plug block 131 is gradually inserted into the frame 2, the module group 123 cooperates with the lower mold 21 to preliminarily extrude the raw material, and the slope at the bottom of the plug block 131 pushes the locking rod 134, so that the locking rod 134 is retracted into the frame 2 and makes way for the movement of the plug block 131. When the extrusion of the raw material is completed, the locking rod 134 is opposite to the socket on the plug block 131. The locking rod 134 is inserted into the socket under the action of the spring and pushes the connecting rod 133. The connecting rod 133 drives the locking block 132 to move, so that the locking block 132 is retracted into the plug block 131 and separated from the installation shell 1. At this time, the installation frame 13 and the installation shell 1 are separated, and the installation shell 1 can continue to move downward with the upper plate 11.

[0073] As another embodiment further provided by the present invention, a shift plate 135 is provided on the inserting block 131 and is magnetically matched with the mounting shell 1 . The shift plate 135 moves to enable the locking block 132 to move relative to the inserting block 131 .

[0074] Specifically, there is a magnetic fit between the top of the dial plate 135 and the mounting shell 1, a spring is provided between the dial plate 135 and the plug block 131, triangular grooves 136 are symmetrically provided on the dial plate 135, the hypotenuses of the two triangular grooves 136 are closest to each other, and the distance between the two hypotenuses decreases from bottom to top, and a tenon 116 adapted to the triangular groove 136 is provided on the locking block 132.

[0075] Furthermore, when the mounting shell 1 moves to the lowest point, the mounting shell 1 is magnetically connected to the dial plate 135, and then the mounting shell 1 moves upward, and the mounting shell 1 moves upward with the dial plate 135, and the hypotenuse of the triangular groove 136 on the dial plate 135 pushes the tenon 116, so that the tenon 116 moves with the locking block 132 to the outside of the plug block 131, and the connecting rod 133 pushes the locking rod 134, so that the slope at the bottom of the locking rod 134 is opposite to the side of the plug block 131, and the locking block 132 is inserted into the locking groove on the mounting shell 1 to lock the mounting frame 13 on the mounting shell 1, and the mounting shell 1 continues to move upward, and the locking block 132 moves along the slope at the bottom of the locking rod 134, pushing the locking rod 134 to make way for the locking block 132 to move.

[0076] As another embodiment further provided by the present invention, a rack 137 for driving the plurality of guide plates 127 to rotate is disposed on the mounting frame 13 , and the shift plate 135 moves relative to the insert block 131 so that the rack 137 drives the guide plates 127 to rotate.

[0077] Specifically, the guide plate 127 is provided with a connecting tube 121 extending to the inside of the mounting frame 13, a torsion spring is provided between the connecting tube 121 and the mounting frame 13, a gear ring 138 meshing with the rack 137 is provided on the connecting tube 121, a pull cable 112 is provided between the shift plate 135 and the rack 137, the rack 137 is slidably installed on the mounting frame 13 and a spring is provided between the rack 137 and the mounting frame 13, and a spring is provided between the guide plate 127 and the plug block 131.

[0078] Furthermore, when the tile pressing work is carried out, the raw material is first put into the lower mold 21 on the frame 2, and then the installation shell 1 is driven to move downward. The installation shell 1 drives the upper plate 11 and the module group 123 to move downward, and the module group 123 contacts the tile raw material first. The module group 123 cooperates with the lower mold 21 to preliminarily extrude the raw material, and presses part of the tile raw material into a truncated cone shape. The limiting ring 22 limits the tile raw material located below the module group 123 to avoid the bottom edge of the truncated cone being crushed due to the movement of the raw material, thereby ensuring the molding of the raw material at the bottom of the module group 123, and the upper plate 11 on the installation shell 1 is also embedded in the frame 2 to close the chamber formed by the frame 2 and the lower mold 21 to avoid splashing of part of the raw material when the module group 123 extrude the tile raw material. At the same time, the installation frame 13 The insert block 131 on the upper part is gradually inserted into the frame 2, and the module group 123 cooperates with the lower mold 21 to preliminarily extrude the raw material, and the slope at the bottom of the insert block 131 pushes the locking rod 134, so that the locking rod 134 is retracted into the frame 2 and makes way for the movement of the insert block 131. When the extrusion of the raw material is completed, the locking rod 134 is directly opposite to the insertion hole on the insert block 131. The locking rod 134 is inserted into the insertion hole under the action of the spring and pushes the connecting rod 133. The connecting rod 133 drives the locking block 132 to move, so that the locking block 132 is retracted into the insert block 131 and separated from the mounting shell 1, and the tenon 116 on the locking block 132 moves along the horizontal side of the triangular groove 136 to the hypotenuse. At this time, the mounting frame 13 and the mounting shell 1 are separated, and the mounting shell 1 can continue to move downward with the upper plate 11.

[0079] Then the mounting shell 1 continues to move downward with the upper plate 11, vibrating and pressing the raw material downward, so that the raw material can move to the flange 124 of the module group 123, and the upper plate 11 cooperates with the lower mold 21 to press the raw material into a blank, and the groove left by the limiting ring 22 on the blank can better adhere to the glaze. When the mounting shell 1 moves to the lowest point, the blank is pressed, and the mounting shell 1 is magnetically connected to the dial plate 135. Then the mounting shell 1 moves upward, and the mounting shell 1 moves upward with the dial plate 135 relative to the plug block 131. The spring between the dial plate 135 and the plug block 131 is stretched, and the dial plate 135 drives the rack 137 to move through the cable 112, and the rack 137 drives the connecting tube 12 through the toothed ring 138 engaged therewith. 1 rotates, thereby driving the guide plate 127 to rotate, and the first guide groove 128 (the same as the arc portion 114) on the guide plate 127 pushes the protrusion on the first module 125, driving the first module 125 to move into the installation cylinder 122, leaving sufficient space for the movement of the second module 126. At this time, the protrusion on the second module 126 moves along the ring portion 113, and the relative position of the second module 126 and the installation cylinder 122 remains unchanged. The guide plate 127 continues to rotate, and the protrusion on the second module 126 enters the arc portion 114 of the second guide groove 129. The arc portion 114 of the second guide groove 129 pushes the protrusion on the second module 126, thereby driving the second module 126 to move into the installation cylinder 122;

[0080] At the same time, the hypotenuse of the triangular groove 136 on the shift plate 135 pushes the tenon 116, so that the tenon 116 moves with the locking block 132 to the outside of the plug block 131, and the connecting rod 133 pushes the locking rod 134, so that the slope at the bottom of the locking rod 134 is opposite to the side of the plug block 131. At this time, the locking block 132 is inserted into the locking groove on the mounting shell 1, and the mounting frame 13 is locked on the mounting shell 1. The tenon 116 on the locking block 132 moves to the lowest point of the hypotenuse of the triangular oblique groove. At this time, the first module 125 and the second module 126 are both retracted into the inside of the mounting cylinder 122. There is no protruding part on the outside of the mounting cylinder 122, and the mounting cylinder 122 can be pulled vertically upward to above the blank. The mounting shell 1 continues to move upward, and the locking block 132 moves along the slope at the bottom of the locking rod 134, pushing the locking rod 134 to make way for the locking block 132 to move, and the mounting cylinder 122 is separated from the blank.

[0081] Then, the shift plate 135 moves downward relative to the plug block 131 under the traction of the spring, the tenon 116 on the lock block 132 moves to the vertex of the vertical side of the triangular groove 136, the cable 112 between the shift plate 135 and the rack 137 is relaxed, and the connecting tube 121 rotates in the opposite direction under the action of the torsion spring, so that the second module 126 and the first module 125 extend to the outside of the installation tube 122 in turn, forming a flange 124 located on the outside of the installation tube 122, ready for the next work.

[0082] Then the lower mold 21 moves upward to push the blank out of the frame 2. At this time, the blank can be taken out. The blank is made into a finished tile after firing, glazing and other processes. When the tile is in use, cement mortar is applied to the back of the tile, and the cement mortar will enter the semi-enclosed cavity on the tile. The cement mortar gradually solidifies in the cavity to form a wedge fixed in the tile, and cooperates with the cement mortar outside the cavity to fix the tile on the wall.

[0083] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
