[0001] The utility model relates to the technical field of molding dies, in particular to a gypsum extrusion molding die. Background Art
[0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, good sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. It has been widely used in various buildings such as residences, office buildings, shops, hotels and industrial plants for interior partitions, wall coverings (instead of wall plastering), ceilings, sound-absorbing panels, ground base panels and various decorative panels.
[0003] Gypsum board is usually formed by extrusion, but the gypsum slurry is often directly injected into the molding mold, resulting in a high air content in the gypsum slurry in the mold. Pores appear on the surface after extrusion molding, and the surface of the gypsum board is rough and uneven after molding, affecting the aesthetics. In addition, the overall strength of the gypsum board is low and it is easy to break during use. Given the wide application of gypsum boards in buildings, there are serious safety hazards. Utility Model Content

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0025] See also Figure 1-4 A gypsum extrusion molding mold comprises a workbench 1, on which a bottom plate 2 is provided, and a pressure groove 21 is provided on the bottom plate 2; it also comprises a driving mechanism arranged on the workbench 1, and an exhaust mechanism is fixedly connected to the lower side of the driving mechanism; the exhaust mechanism comprises a spring 3 arranged in the driving mechanism, and the two ends of the spring 3 are respectively fixedly connected to the driving mechanism and the baffle 31, and the baffle 31 is slidably connected to the driving mechanism, and a connecting rod 32 is fixedly connected to the baffle 31, and a pressing plate 4 adapted to the pressure groove 21 is fixedly connected to the end of the connecting rod 32, and a grouting port 41 is provided on the pressing plate 4, and a one-way valve 42 is provided on the grouting port 41.
[0026] In the initial state, the pressing plate 4 abuts against the pressing groove 21 to expel the air between the two, and the gypsum slurry is injected through the grouting port 41 on the pressing plate 4, and the gypsum slurry enters between the pressing plate 4 and the pressing groove 21. As the gypsum slurry is continuously injected, the pressing plate 4 is lifted, and the pressing plate 4 moves up to compress the spring 3 through the connecting rod 32 and the baffle 31. When a sufficient amount of gypsum slurry is injected, the one-way valve 42 is closed to prevent the gypsum slurry from leaking from the grouting port 41 during the extrusion molding process, and the driving mechanism is started to drive the spring 3, the baffle 31 and the connecting rod 32 to move downward, thereby squeezing the gypsum slurry into shape through the pressing plate 4. Since only a small amount of air enters the gypsum slurry through the gap between the pressing groove 21 and the pressing plate 4 during the gypsum slurry injection and extrusion molding process, its overall air content is relatively small, and no pores will appear to affect the strength.
[0027] When the injected gypsum board pushes the pressure plate 4 to the lower end of the lifting rod 53, the spring 3 is not compressed to the limit value, that is, the spring 3 will not be damaged due to exceeding the compression limit during operation.
[0028] In an embodiment further provided by the utility model, the driving mechanism includes a frame 5 fixedly arranged on the workbench 1, a hydraulic cylinder 51 fixedly connected to the frame 5, a lifting plate 52 fixedly connected to the output end of the hydraulic cylinder 51, a lifting rod 53 fixedly connected to the lifting plate 52, the baffle 31 is slidably connected to the inside of the lifting rod 53, the spring 3 is fixedly connected to the lifting rod 53, the hydraulic cylinder 51 pushes the lifting plate 52 to move downward, the lifting plate 52 drives the lifting rod 53 to move downward, and the lifting rod 53 drives the pressure plate 4 to move downward through the spring 3, the baffle 31 and the connecting rod 32 arranged therein, thereby realizing the extrusion molding of gypsum.
[0029] In an embodiment further provided by the utility model, there are multiple lifting rods 53 and exhaust mechanisms, and they are arranged one by one. The lifting rods 53 are arranged at the four corners and the middle position of the pressing plate 4 to avoid uneven local force on the pressing plate 4, which leads to inconsistent thickness of the extruded gypsum board and affects actual use.
[0030] In an embodiment further provided by the utility model, a placement groove 11 adapted to the base plate 2 is provided on the workbench 1, and two slide grooves 12 are provided in the placement groove 11. A slider 22 adapted to the slide groove 12 is fixedly provided on the lower side of the base plate 2, and the slider 22 is slidably connected to the slide groove 12. The sliding connection between the slider 22 and the slide groove 12 is realized by the sliding connection between the base plate 2 and the placement groove 11 of the workbench 1, and the base plate 2 equipped with the extruded gypsum board can be directly slid out and replaced with a new base plate 2 for the next batch of pressing.
[0031] In an embodiment further provided by the present invention, a handle 23 is fixedly provided on the side wall of the bottom plate 2 to facilitate the base to be pulled out from the workbench 1 .
[0032] In an embodiment further provided by the utility model, a convex strip 43 is provided on the pressure plate 4, and a groove 54 corresponding to the convex strip 43 is provided on the frame 5. The convex strip 43 and the groove 54 are slidably connected. Through the sliding connection between the convex strip 43 and the groove 54, the movement of the pressure plate 4 in the vertical direction is limited to prevent it from being offset.
[0033] In an embodiment further provided by the present invention, a decorative groove is provided on the surface of the pressing plate 4 opposite to the pressing groove 21, and corresponding decorative patterns are formed on the surface of the extruded gypsum board.
[0034] Working principle:
[0035] In the initial state, the pressing plate 4 abuts against the pressing groove 21 to discharge the air therebetween, and gypsum slurry is injected through the grouting port 41 on the pressing plate 4, and the gypsum slurry enters between the pressing plate 4 and the pressing groove 21. As the gypsum slurry is continuously injected, the pressing plate 4 is lifted, and the pressing plate 4 moves up to compress the spring 3 through the connecting rod 32 and the baffle 31. When a sufficient amount of gypsum slurry is injected, the one-way valve 42 is closed to prevent the gypsum slurry from leaking out of the grouting port 41 during the extrusion molding process, and the hydraulic cylinder 51 is started to push the lifting plate 52 downward, and the lifting plate 52 drives the lifting rod 53 downward, and the lifting rod 53 drives the pressing plate 4 downward through the spring 3, the baffle 31 and the connecting rod 32 arranged therein, thereby squeezing the gypsum slurry through the pressing plate 4 to form it. Since only a small amount of air enters the gypsum slurry through the gap between the pressing groove 21 and the pressing plate 4 during the gypsum slurry injection and extrusion molding process, its overall air content is small, and no pores will appear to affect the strength.
[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. 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.
