The forming enclosure is sleeved on the outer periphery of the upper mold and is slidably connected to the upper mold.

[0006] The lower mold assembly includes a base and a lower mold. The lower mold is fixed on the base. The upper side surface of the lower mold is consistent in shape with the lower side surface of the upper mold. The lower end surface of the forming enclosure can abut against the upper end surface of the base. The side wall of the forming enclosure, the upper side surface of the lower mold and the lower side surface of the upper mold form a cavity for forming a green tile.

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described in conjunction with the embodiments below. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention. As used herein, the terms up and down and left and right are not limited to their strict geometric definitions, but include reasonable and inconsistent tolerances for machining or human errors. The specific features of the molding device of a tile making machine are described in detail below:

[0027] An embodiment of the present invention:

[0028] Reference Figure 1-Figure 6 The present invention provides a molding device for a tile making machine, comprising an upper mold assembly, a lower mold assembly and a frame 10, wherein the upper mold assembly and the lower mold assembly are both mounted on the frame 10, and the upper mold assembly is located on the upper side of the lower mold assembly;

[0029] The upper mold assembly includes an upper mold 20, a hydraulic cylinder 21 and a forming enclosure 40. The upper mold 20 is lifted and lowered by the extension and retraction of the hydraulic cylinder 21. The forming enclosure 40 is sleeved on the outer periphery of the upper mold 20 and is slidably connected to the upper mold 20.

[0030] The lower mold assembly includes a base 30 and a lower mold 31. The lower mold 31 is fixed on the base 30. The upper side surface of the lower mold 31 is consistent in shape with the lower side surface of the upper mold 20. The lower end surface of the forming enclosure 40 can be abutted against the upper end surface of the base 30. The side wall of the forming enclosure 40, the upper side surface of the lower mold 31 and the lower side surface of the upper mold 20 form a cavity for forming a green tile. The upper mold 20 and the lower mold 31 are used to extrude the clay green tile to form a green tile in the cavity.

[0031] Reference Figure 5 The left and right side surfaces of the upper mold 20 are both provided with inwardly recessed limit grooves 27, and the inner wall of the forming enclosure 40 is respectively close to the two limit grooves 27. The limit plate 41 is slidably connected to the limit grooves 27. The sliding connection between the limit grooves 27 and the limit plate 41 can limit the sliding distance of the forming enclosure 40 to prevent the forming enclosure 40 from being separated from the upper mold 20 during the sliding process.

[0032] Reference Figure 5 A spring ring 23 is arranged in the limiting groove 27. The spring ring 23 is elliptical. The upper and lower side surfaces of the spring ring 23 are respectively in contact with the upper side wall of the limiting groove 27 and the upper end surface of the limiting plate 41. The spring ring 23 is made of spring steel and has good elastic deformation ability. Under the elastic force of the spring ring 23, the forming enclosure 40 can be reset after the upper mold assembly squeezes the lower mold assembly.

[0033] Reference Figure 5 The upper end surface of the upper mold 20 is provided with two symmetrical and downwardly recessed fixing grooves 26, which are respectively connected with the two limiting grooves 27. A limiting rod 22 is fixed in the fixing groove 26 by bolts, and the upper side of the spring ring 23 abuts against the lower side of the limiting rod 22. The setting of the limiting rod 22 facilitates the installation of the spring ring 23, and also facilitates the replacement and maintenance of the spring ring 23.

[0034] Reference Figure 5 The left and right side walls of the forming enclosure 40 are provided with through grooves 42 corresponding to the limit grooves 27, and the limiting plate 41 passes through the through grooves 42. The upper side walls of the through grooves 42 are provided with two front-to-rear symmetrical circular holes, and the upper ends of the circular holes are opened. The limiting plate 41 is provided with two through holes corresponding to the circular holes, and the circular holes are embedded with pins 43 passing through the through holes. The setting of the pins 43 allows the limiting plate 41 to be detachably installed in the through grooves 42, so that the limiting plate 41 can be easily disassembled from the forming enclosure 40, thereby facilitating the separation of the forming enclosure 40 from the upper mold 20.

[0035] Reference Figure 3-Figure 5 The lower side of the upper mold 20 is provided with an engaging groove 28 which surrounds the edge and is concave upward. A fixing seat 24 which surrounds the edge is fixed in the engaging groove 28. A groove which is concave upward is provided in the lower side of the fixing seat 24. A washer 25 is arranged on the lower side of the fixing seat 24. A convex strip which protrudes upward is fixed on the upper side of the washer 25. The convex strip is embedded in the groove of the fixing seat 24 and is fixedly connected thereto. The lower side of the washer 25 is flush with the lower side of the upper mold 20. The outer periphery of the washer 25 abuts against the inner side wall of the fixing seat 24. The fixing seat 24 is made of copper. The outer periphery of the gasket 25 abuts against the inner wall of the fixed seat 24. The gasket 25 is made of rubber. By utilizing the elasticity of the gasket 25, the outer periphery of the gasket 25 abuts against the inner wall of the forming enclosure 40, so that the gasket 25 will not scratch the inner wall of the forming enclosure 40 when sliding along the forming enclosure 40. At the same time, the setting of the fixed seat 24 increases the connection strength between the gasket 25 and the upper mold 20. At the same time, when the copper fixed seat 24 abuts against the inner wall of the forming enclosure 40, the fixed seat 24 has a certain lubricating effect, thereby preventing the fixed seat 24 from scratching the inner wall of the forming enclosure 40.

[0036] Reference Figure 5 A motor base 53 is fixed on the upper mold 20, a motor 50 is fixed inside the motor base 53, an eccentric wheel 52 is fixed on the output shaft of the motor 50, a protective cover 51 is fixed on the motor base 53, the protective cover 51 covers the eccentric wheel 52, when the motor 50 rotates on behalf of the eccentric wheel 52, the eccentric structure of the eccentric wheel 52 causes it to generate high-frequency vibration, thereby driving the upper mold assembly to vibrate at a high frequency, thereby accelerating the separation of the green tile from the upper mold assembly.

[0037] Reference Figure 1 An upper fixed plate 11 is fixed to the upper end of the hydraulic cylinder 21, and the upper fixed plate 11 is fixed to the frame 10. The upper mold 20 is fixed to the lower end of the piston rod of the hydraulic cylinder 21. A lower fixed plate 13 is fixed to the lower end surface of the base 30, and the lower fixed plate 13 is fixed to the frame 10. A plurality of reinforcing ribs 12 are fixed on the opposite sides of the upper fixed plate 11 and the lower fixed plate 13. The setting of the reinforcing ribs 12 improves the bending strength of the upper fixed plate 11 and the lower fixed plate 13.

[0038] When in use, a certain amount of clay is placed on the lower mold 31 according to the thickness and size of the tile blank, and then the hydraulic cylinder 21 is started, and the piston rod thereon is extended, which drives the upper mold 20 to move downward. When the forming plate 40 abuts against the base 30, the forming plate 40 stops moving, and the upper mold 20 continues to press down, then the forming plate 40 and the upper mold 20 move relative to each other, that is, the forming plate 40 moves upward relative to the upper mold 20, and the spring ring 23 is squeezed and deformed. At this time, the cavity formed by the upper mold 20, the lower mold 31 and the forming plate 40 squeezes the clay blank into a tile blank.

[0039] After the tile is formed, the hydraulic cylinder 21 contracts and the upper mold 20 moves upward. Due to the elastic force of the spring coil 23, a relative displacement occurs between the forming plate 40 and the upper mold 20, that is, the forming plate 40 moves downward relative to the upper mold 20. If the tile is adhered to the lower side of the upper mold 20 at this time, the forming plate 40 moves downward relative to the upper mold 20. Under the action of the friction between the forming plate 40 and the outer periphery of the tile, the forming plate 40 pushes the edge of the tile downward, so that the edge of the tile is separated from the lower side of the upper mold 20.

[0040] When the hydraulic cylinder 21 contracts and the upper mold 20 moves upward, the motor 50 is powered on and started, driving the eccentric wheel 52 to rotate and generate high-frequency vibration, thereby driving the upper mold 20 to vibrate, thereby accelerating the separation of the green tile from the upper mold 20, and the green tile falls onto the lower mold 31. After the upper mold assembly is reset, the hydraulic cylinder 21 is closed.

[0041] Finally, the green tile that falls onto the lower mold 31 is taken away, and the green tile is placed on a supporting component with the same curvature as the lower mold 31. After the green tile is dried in the shade, it can be fired to finally form a tile.

[0042] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention. All of these modifications fall within the scope of protection of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
