Description

Technical Field

[0001] This utility model belongs to the technical field of plaster shaping mechanism, specifically relating to a high-strength plaster shaping mechanism. Background Technology

[0002] Gypsum is a hydrated form of calcium sulfate, a monoclinic mineral. It is a widely used industrial and building material. When processing gypsum into building materials, it needs to be shaped. This is usually done by a shaping mechanism. The existing shaping mechanism is the equipment used for shaping during gypsum processing. It is convenient to inject gypsum raw materials into the shaping mold base. The movement of the hydraulic cylinder drives the moving connecting plate and the shaping block to move down until the shaping block is moved into the interior of the shaping mold base for tight shaping. This results in high-strength, tight-press shaping of the gypsum board.

[0003] According to the plasterboard shaping device disclosed in the authorized patent application number CN202020656492.0, which facilitates demolding, the existing shaping mechanism moves a push plate driven by an electric cylinder after the plaster is shaped. The push plate demolds the plaster during the movement of the push plate. However, the movement of the electric cylinder during demolding is relatively fast, which is not convenient for slow and uniform force operation. At the same time, the plaster is prone to deformation and damage to the lower surface of the shaped plaster during rapid ejection operation shortly after it is shaped. This affects the convenience of the shaping mechanism in terms of uniform force and slow demolding after the plaster is shaped. Therefore, this utility model proposes a high-strength plaster shaping mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength plaster molding mechanism to solve the problems mentioned in the background art. After the plaster molding process, the molding mechanism drives the push plate to move under the action of the electric cylinder. When the push plate moves, the plaster is demolded. During demolding, the electric cylinder moves relatively quickly to eject the plaster, which is not convenient for slow and uniform force operation. At the same time, when the plaster is quickly ejected after molding, the lower surface of the molded plaster is easily deformed and damaged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength gypsum shaping mechanism, comprising a shaping mechanism body, the shaping mechanism body including a base, a shaping mold base fixedly installed at the middle position of the upper surface of the base, a top frame welded to the top of the upper surface of the base, a hydraulic cylinder fixedly installed at the top of the top frame, a movable connecting plate fixedly fixed at the end of the hydraulic cylinder inside the top of the top frame, a shaping pressure block fixed to the lower surface of the movable connecting plate by bolts, control slide rods fixed at the connection points between the top of the top frame and both sides of the upper surface of the base, two control sliding holes opened at both ends of the movable connecting plate, and the control slide rods passing through the interior of the control sliding holes, the shaping mechanism body also being provided with:

[0006] A uniform force slow demolding mechanism, which includes a drive assembly disposed at the bottom of the mold base, and two sets of moving adjustment assemblies disposed at both ends of the drive assembly inside the base, and a uniform force slow demolding assembly disposed at the connection of the upper surfaces of the two sets of moving adjustment assemblies.

[0007] A cleaning mechanism, comprising a mounting assembly disposed at the bottom end of a control slide hole within a movable connecting plate, wherein a scraping cleaning component is disposed at the bottom inner end of the mounting assembly.

[0008] Preferably, the driving assembly includes a rotating rod that rotates at the middle position inside the bottom end of the forming mold base. A forward and reverse motor is installed at the end of the rotating rod inside the forming mold base, and a drive torsion gear is fixedly installed at both ends of the rotating rod.

[0009] Preferably, the movable adjustment assembly includes a movable groove formed inside the bottom end of the shaping mold base, with lead screws rotating at both ends inside the movable groove, a movable plate provided on the outer surface of the lead screws, and a driven torsion gear installed at the bottom end of the lead screws, and the driven torsion gear meshing with the driving torsion gear.

[0010] Preferably, the inner middle position of the moving plate matches the outer surface structure of the lead screw, and the rotating rod and the lead screw are adjusted by the driven torsion gear and the driving torsion gear.

[0011] Preferably, the uniformly stressed and slowly demolding assembly includes a placement groove at the bottom of the mold base, a demolding base plate is provided inside the placement groove, a sealing gasket is engaged at the edge of the demolding base plate, push rods are welded at the four corners of the upper surface of the moving plate, a sliding hole is provided at the top of the moving groove, the push rod passes through the sliding hole, and the top of the push rod is fixed to the bottom of the demolding base plate by welding.

[0012] Preferably, the mounting assembly includes a mounting groove formed at the bottom end of the control sliding hole inside the movable connecting plate, and a retaining ring is fixedly mounted inside the mounting groove by screws.

[0013] Preferably, the scraping and cleaning assembly includes a scraper ring disposed at the bottom of the inner end of the fixed ring, the inner surface of the scraper ring contacting the surface of the control slide rod, and an integrally formed mounting ring on the upper surface of the scraper ring, the mounting ring being fixed to the interior of the fixed ring by screws.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a uniform force and slow demolding mechanism, when the gypsum board is demolded after being shaped by the main body of the shaping mechanism, the forward and reverse motor drives the rotating rod and the active torsion gear to rotate. When the active torsion gear rotates, it meshes with the outer surface of the driven torsion gear, causing the driven torsion gear and the lead screw to rotate. This causes the two lead screws to rotate simultaneously, driving the moving plate and the ejector rod to move upward. This allows multiple ejector rods to move simultaneously, causing the demolding base plate to be uniformly forcefully and slowly ejected from the mold. The gypsum board that has just been shaped is not easily damaged during ejection, thus enabling the gypsum board to be shaped and demolded with high strength. This improves the convenience of uniform force and slow demolding when the gypsum board is demolded after being shaped by the main body of the shaping mechanism. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] See also Figures 1 to 7 This utility model provides a technical solution: a high-strength gypsum molding mechanism, including a molding mechanism body 100, the molding mechanism body 100 including a base 101, a molding mold base 102 fixedly installed at the middle position of the upper surface of the base 101, when the molding mechanism body 100 is placed for operation, the demolding base plate 109 is sealed and closed to the inner bottom end of the molding mold base 102 by a sealing gasket, and gypsum raw material is injected into the interior of the molding mold base 102. A [missing information - likely a component or material] is welded to the top of the upper surface of the base 101. A top frame 108 is provided, and a hydraulic cylinder 107 is fixedly installed at the top of the top frame 108. The end of the hydraulic cylinder 107 is located inside the top of the top frame 108, and a movable connecting plate 103 is fixed at the top. A shaping block 104 is fixed to the lower surface of the movable connecting plate 103 by bolts. The movement of the hydraulic cylinder 107 drives the movable connecting plate 103 and the shaping block 104 to move down until the shaping block 104 moves down into the interior of the shaping mold base 102 for tight lowering and shaping, so that the gypsum board is subjected to high-strength tight pressing and shaping treatment.

[0026] Control slide rods 106 are fixed at the connection points between the top of the top frame 108 and both sides of the upper surface of the base 101. Two control slide holes 105 are provided at both ends of the movable connecting plate 103, and the control slide rods 106 pass through the interior of the control slide holes 105. When the movable connecting plate 103 moves, it slides along the outer surface of the control slide rods 106 through the control slide holes 105, allowing the shaping block 104 to move stably downwards for shaping. The main body 100 of the shaping mechanism also includes:

[0027] The uniform force slow demolding mechanism includes a drive assembly located at the bottom of the mold base 102. Two sets of moving adjustment assemblies are located inside the base 101 at both ends of the drive assembly. The uniform force slow demolding assembly is located at the connection between the upper surfaces of the two sets of moving adjustment assemblies. After the mold body 100 shapes the gypsum board, the uniform force slow demolding mechanism slowly demolds the shaped gypsum board. It is not easy to be damaged during ejection demolding, so that the gypsum board is shaped and demolded with high strength, which improves the convenience of uniform force slow demolding when the mold body 100 shapes the gypsum board.

[0028] To facilitate simultaneous rotation adjustment of the two lead screws 1095 via the drive assembly, in this embodiment, preferably, the drive assembly includes a rotating rod 1097 located at the middle position inside the bottom end of the shaping mold base 102. A forward and reverse motor 1098 is installed at the end of the rotating rod 1097 inside the shaping mold base 102. Both ends of the rotating rod 1097 are fixedly mounted with active torsion gears 1090. When the forward and reverse motor 1098 is energized and driven, it drives the rotating rod 1097 to rotate. When the rotating rod 1097 rotates, it drives the active torsion gears 1090 to rotate, facilitating rotation adjustment.

[0029] To facilitate the simultaneous movement and adjustment of the two movable plates 1094 via the movable adjustment assembly, in this embodiment, preferably, the movable adjustment assembly includes a movable groove 1096 formed inside the bottom end of the shaping mold base 102. Both ends of the movable groove 1096 are rotatably fitted with lead screws 1095. Movable plates 1094 are mounted on the outer surface of the lead screws 1095. A driven torsion gear 1099 is installed at the bottom end of the lead screw 1095, and the driven torsion gear 1099 meshes with the driving torsion gear 1090. This facilitates the rotation of the driving torsion gear 1090 onto the outer surface of the driven torsion gear 1099, causing the lead screw 1095 to rotate. This allows the two movable plates 1094 to rotate simultaneously, and the two movable plates 1094 can be moved and adjusted simultaneously when the two lead screws 1095 rotate simultaneously.

[0030] To facilitate the slow demolding of the shaped plaster using a uniformly stressed, slow demolding assembly, in this embodiment, preferably, the uniformly stressed, slow demolding assembly includes a placement groove 1091 formed at the bottom of the mold base 102. A demolding base plate 109 is disposed inside the placement groove 1091, and a sealing gasket is fitted at the edge of the demolding base plate 109. This allows the demolding base plate 109 to be sealed by the sealing gasket when closed inside the placement groove 1091, facilitating shaping. Push rods 1 are welded to the four corners of the upper surface of the moving plate 1094. 093, a sliding hole 1092 is provided at the top of the inner side of the moving groove 1096, and the push rod 1093 passes through the sliding hole 1092. The top end of the push rod 1093 is welded to the bottom end of the demolding base plate 109. When the moving plate 1094 moves, it can drive the push rod 1093 to move. The push rod 1093 is controlled to slide inside the sliding hole 1092, so that the push rod 1093 slides stably and drives the placement groove 1091 to be evenly stressed and slowly move upward to demold the shaped gypsum board. This facilitates demolding and is less likely to damage the shaped gypsum board.

[0031] The cleaning mechanism includes an installation component located inside the movable connecting plate 103 at the bottom end of the control sliding hole 105. The bottom end of the installation component is equipped with a scraping and cleaning component. When the shaping mechanism body 100 is fixedly installed and used, if plaster sticks adhere to the outer surface of the control sliding rod 106, the movable connecting plate 103 slides and drives the cleaning mechanism to slide and scrape the outer surface of the control sliding rod 106, making it less likely to be obstructed when the control sliding rod 106 slides between the control sliding hole 105.

[0032] To facilitate the fixed installation and use of the scraper ring 1063 and the mounting ring 1064 through the installation component, in this embodiment, preferably, the installation component includes a mounting groove 1061 opened at the bottom end of the control sliding hole 105 and located inside the movable connecting plate 103. A fixing ring 1062 is fixedly installed inside the mounting groove 1061 by screws. The fixing ring 1062 can be closed and installed inside the mounting groove 1061, and the scraper ring 1063 can be fixedly installed inside the fixing ring 1062 again, which facilitates installation and use.

[0033] To facilitate the scraping and cleaning of the outer surface of the control slide bar 106 and improve sliding control, in this embodiment, preferably, the scraping and cleaning assembly includes a scraping ring 1063 disposed at the bottom of the inner end of the fixing ring 1062. The inner surface of the scraping ring 1063 contacts the surface of the control slide bar 106. An integral mounting ring 1064 is disposed on the upper surface of the scraping ring 1063. The mounting ring 1064 is fixed to the interior of the fixing ring 1062 by screws. When the movable connecting plate 103 is in the sliding control position on the outer surface of the control slide bar 106, the scraping ring 1063 is driven to contact the outer surface of the control slide bar 106 for scraping and cleaning, so that the movable connecting plate 103 can be smoothly controlled to slide.

[0034] The working principle and usage process of this utility model: When the main body 100 of this high-strength plaster molding mechanism is demolded after operation, the forward and reverse motor 1098 drives the rotating rod 1097 and the active torsion gear 1090 to rotate. When the active torsion gear 1090 rotates, it meshes with the outer surface of the driven torsion gear 1099, causing the driven torsion gear 1099 and the lead screw 1095 to rotate. This causes both lead screws 1095 to rotate simultaneously, driving the moving plate 1094 and the ejector rod 1... 093 moves upward, thereby moving multiple ejector rods 1093 simultaneously to push out the demolding base plate 109. When ejecting, the ejector rods 1093 are inside the sliding hole 1092 for sliding control. At this time, it is easy to push out the demolding base plate 109 with uniform force. The gypsum board that has just been shaped is not easily damaged when it is ejected and demolded, thus enabling the gypsum board to be shaped and demolded with high strength. This improves the convenience of the main body 100 of the shaping mechanism for the uniform force and slow demolding of the gypsum board after shaping.

[0035] Finally, before using the shaping mechanism body 100, the scraper ring 1063 and the fixing ring 1062 are inserted through the outer surface of the control slide rod 106, and the fixing ring 1062 is fixed inside the mounting groove 1061. When gypsum material is injected into the shaping mold base 102 for shaping, if the surface of the control slide rod 106 jumps or touches the gypsum material, the hydraulic cylinder 107 drives the moving connecting plate 103 and the shaping pressure block 104 to move down and slide on the outer surface of the control slide rod 106. When the moving connecting plate 103 slides on the outer surface of the control slide rod 106, it drives the fixing ring 1062 and the scraper ring 1063 to slide. The scraper ring 1063 contacts the outer surface of the control slide rod 106 and moves to scrape and clean the attached material, so that the sliding control between the control slide rod 106 and the control sliding hole 105 is not easily obstructed. This improves the convenience of scraping and cleaning the outer surface of the control slide rod 106 when the shaping mechanism body 100 is shaping gypsum, and smoothly slides down for shaping.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
