Description

Technical Field

[0001] This invention relates to the field of energy-saving building material production technology, specifically to a high-efficiency molding device for steel slag concrete bricks. Background Technology

[0002] Steel slag concrete bricks, as an energy-saving building material, have advantages such as environmental friendliness, high strength, and good sound and heat insulation properties, and are widely used in construction projects. However, existing steel slag concrete brick forming equipment still has many problems in actual production, which restricts the improvement of production efficiency and product quality. 1. Traditional steel slag concrete brick forming equipment mostly adopts a single compaction or vibration method, which makes it difficult to efficiently degas and uniformly compact the steel slag concrete raw materials. Air is easily retained in the mold cavity, resulting in defects such as hollowness, delamination, and cracking inside the brick. This not only affects the core indicators of the brick such as compressive strength and impermeability, but also increases the safety hazards of construction due to unstable product quality. 2. Steel slag concrete raw materials have strong adhesion. After molding, they are easy to adhere tightly to the inner wall of the mold cavity, and even form negative pressure adsorption. Existing demolding methods mostly rely on mechanical pushing or simply gravity separation, which not only has low demolding efficiency, but also easily causes damage to the edges and corners of the bricks and scratches on the surface during the demolding process, which greatly affects the product quality. 3. The existing equipment lacks an automatic cleaning function for the mold. After molding, the raw material residue remaining on the inner wall of the mold cavity needs to be cleaned manually, which is time-consuming and labor-intensive, seriously affecting the subsequent production efficiency and making it difficult to meet the needs of modern building materials production for large-scale and high-efficiency production. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency molding device for steel slag concrete bricks to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency molding device for steel slag concrete bricks, comprising a base plate, a fixing frame fixed on the upper surface of the base plate, a molding mechanism installed on the fixing frame, the molding mechanism cooperating with the mold cavity to realize the secondary vibration, pressing and molding effect of the steel slag concrete bricks, a pad plate fixed on the upper surface of the base plate, a support plate placed on the pad plate, the support plate being located below the mold cavity, a demolding mechanism installed on the mold cavity, and the demolding mechanism utilizing airflow to achieve the auxiliary demolding effect of the steel slag concrete bricks from the mold cavity.

[0005] Preferably, the forming mechanism includes a first cylinder fixed on a fixed frame, and a movable plate is fixed to the output end of the first cylinder. The movable plate is slidably connected to the vertical rod, and the vertical rod is symmetrically fixed to the fixed plate. A first spring is also fixed between the fixed plate and the movable plate, and the first spring is symmetrically distributed about the center line of the fixed plate. The extension and retraction of the first cylinder can provide a basic force for the vertical movement of the fixed plate and the movable plate. The sliding guide action between the movable plate and the vertical rod can allow the movable plate to move relative to the fixed plate, thereby providing a basic guarantee for the secondary compaction of the steel slag concrete brick. The elastic action of the first spring can provide a basic force for the automatic reset of the movable plate, ensuring the normal operation of the device.

[0006] Preferably, the lower end face of the movable plate is also symmetrically fixed with positioning rods, and the positioning rods contact the fixed plate to achieve positioning. The length of the positioning rods is greater than the height of the vibration motor. At the same time, the vibration motor is fixed on the fixed plate. Positioning is achieved by the positioning rods contacting the fixed plate, which can transform the flexible connection between the movable plate and the fixed plate into a rigid connection. This provides a basic guarantee for the initial venting and subsequent compaction of the steel slag concrete bricks, thereby ensuring the production quality of the steel slag concrete bricks. Furthermore, by limiting the length of the positioning rods, pressure from the movable plate on the vibration motor can be avoided, which could damage the vibration motor and thus ensure the service life of the device.

[0007] Preferably, the fixing plate is fixed to one end of the support rod, and the other end of the support rod is fixed to the pressure plate. The support rods are symmetrically distributed about the center line of the pressure plate. At the same time, the pressure plate and the mold cavity are nested together. The normal production of steel slag concrete bricks can be ensured by the cooperation between the pressure plate and the mold cavity.

[0008] Preferably, a fixing ring is also fixed on the upper surface of the fixing plate, and a scraper made of rubber is fixed on the outside of the fixing ring. The scraper contacts the inner wall of the mold cavity to form a sliding mechanism. Through the sliding action between the scraper and the mold cavity, the residual slag on the inner wall of the mold cavity can be cleaned after the steel slag concrete bricks are produced, ensuring the continuous operation of subsequent production.

[0009] Preferably, the pads are symmetrically distributed about the center line of the support plate, and the size of the support plate is larger than the size of the mold cavity, and the mold cavity is located directly below the pressure plate. The support plate facilitates the transfer of the formed steel slag concrete bricks.

[0010] Preferably, the demolding mechanism includes horizontal plates symmetrically fixed on a fixed frame, and a second cylinder is fixed on the horizontal plate. The output end of the second cylinder is fixed to the mold cavity. The extension and retraction of the second cylinder can provide a basic force for the movement of the mold cavity, thereby providing a basic guarantee for the separation of the mold cavity from the molded steel slag concrete brick.

[0011] Preferably, the horizontal plate and the guide rod are slidably connected, and the guide rod is fixed on the movable frame, which is located outside the mold cavity. At the same time, a second spring is fixed between the movable frame and the horizontal plate. Through the sliding guiding action between the horizontal plate and the guide rod, the stability of the movable frame relative to the horizontal plate can be ensured. Furthermore, through the elastic action of the second spring, a basic force can be provided for the automatic reset of the movable frame, thereby ensuring the normal operation of the device.

[0012] Preferably, a fixing block is fixed to the lower end face of the movable frame, and an inclined groove is provided on the fixing block. The inclined groove is slidably connected to the slide rod, and the slide rod is slidably connected to the mold cavity. One end of the slide rod and the crossbar are fixed to each other, and the other end of the crossbar is fixed to the side plate. The side plate is slidably connected to the vertical groove, and the vertical groove is provided on the side wall of the mold cavity. Through the sliding action between the slide rod and the inclined groove, the crossbar can be moved horizontally under force. Combined with the sliding guiding action between the slide rod and the mold cavity, the stability of the slide rod movement can be ensured. The slide rod drives the side plate to move horizontally, which can provide a basic guarantee for the auxiliary detachment of the steel slag concrete brick.

[0013] Preferably, a piston head is also fixed on the crossbar, and the piston head, crossbar, and cylinder are slidably connected. The cylinder is fixed to the outside of the mold cavity, and a one-way air inlet valve and a one-way air outlet valve are installed on the cylinder. The cylinder is connected to the air guide pipe through the one-way air outlet valve, and the air guide pipe is connected to the air guide groove. The air guide groove is connected to the air guide channel. The air guide channel and the air guide groove are both opened in the mold cavity. The air guide channels are evenly distributed in the mold cavity and are connected to the vertical groove. The air guide channels are sealed with the side plate. The crossbar drives the piston head to slide in the cylinder. With the action of the one-way air inlet valve and the one-way air outlet valve, the gas in the cylinder can flow in one direction. With the action of the air guide pipe, air guide groove, air guide channel, and vertical groove, the gas can fill the space between the mold cavity and the steel slag concrete brick, thereby achieving a better demolding effect for the steel slag concrete brick.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This high-efficiency molding device for steel slag concrete bricks, through its molding mechanism, enables a graded compaction process during the production of steel slag concrete bricks, involving initial flexible vibration venting and subsequent rigid secondary compaction. Initially, the vibration of the motor and the flexible support of the first spring allow the pressure plate to gently vibrate and press down on the raw material in the mold cavity, quickly expelling air from the raw material and preventing hollow areas inside the brick. Later, the positioning rod contacts the fixing plate to form rigid support, which, in conjunction with the continuous extension of the first cylinder, performs secondary rigid compaction on the initially molded raw material, ensuring uniform density inside the steel slag concrete brick. This effectively guarantees the density of the brick blank and effectively avoids quality problems such as brick cracking and delamination, greatly ensuring the production quality of the brick blank. 2. The high-efficiency molding device for steel slag concrete bricks combines mechanical linkage and airflow assistance in the demolding mechanism, effectively ensuring the demolding quality of the brick blanks. After the brick blanks are formed, during the upward movement of the mold cavity, the sliding cooperation of the inclined groove and the slide rod drives the crossbar and the side plate to move. This not only releases the seal of the side plate on the air channel, but also reduces the contact area between the mold cavity and the brick body. At the same time, the piston head slides in the cylinder to generate airflow. The airflow enters the space between the mold cavity and the brick body through the air channel, breaking the negative pressure adsorption, forming fluid lubrication, and providing auxiliary thrust for the demolding of the brick body. This effectively avoids damage to the brick body caused by mechanical pushing, ensuring the non-destructive and efficient separation of the steel slag concrete bricks from the mold cavity, thereby effectively improving the yield of the brick blanks. 3. The high-efficiency molding device for steel slag concrete bricks uses cylinders, springs, connecting rods, and other components to precisely match the timing of the molding and demolding mechanisms. This eliminates the need for complex electrical control systems, significantly simplifying the equipment structure and reducing maintenance difficulty. Simultaneously, the scraper can clean residual slag from the inner wall as it moves upward through the mold cavity, achieving automatic mold cleaning and eliminating the need for manual cleaning. This better meets the needs of large-scale and continuous production, greatly improving production efficiency. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-8 The present invention provides a technical solution: a high-efficiency molding device for steel slag concrete bricks, including a base plate 1, a fixing frame 2 fixed on the upper end surface of the base plate 1, a molding mechanism 3 installed on the fixing frame 2, the molding mechanism 3 cooperating with the mold cavity 6 to realize the secondary vibration and pressing molding effect of the steel slag concrete bricks, a pad plate 4 fixed on the upper end surface of the base plate 1, a support plate 5 placed on the pad plate 4, the support plate 5 being located below the mold cavity 6, a demolding mechanism 7 installed on the mold cavity 6, and the demolding mechanism 7 using airflow to realize the auxiliary demolding effect of the steel slag concrete bricks from the mold cavity 6.

[0019] The molding mechanism 3 includes a first cylinder 301 fixed on the fixed frame 2, and a movable plate 302 fixed to the output end of the first cylinder 301. The movable plate 302 is slidably connected to the vertical rod 303. The vertical rod 303 is symmetrically fixed to the fixed plate 304. A first spring 305 is also fixed between the fixed plate 304 and the movable plate 302, and the first spring 305 is symmetrically distributed about the center line of the fixed plate 304. A positioning rod 306 is also symmetrically fixed to the lower end face of the movable plate 302. The positioning rod 306 contacts the fixed plate 304 to achieve positioning, and the length of the positioning rod 306 is greater than the height of the vibration motor 307. The motor 307 is fixed to the fixed plate 304; the fixed plate 304 is fixed to one end of the support rod 308, and the other end of the support rod 308 is fixed to the pressure plate 309. The support rod 308 is symmetrically distributed about the center line of the pressure plate 309. The pressure plate 309 and the mold cavity 6 are nested together. A fixing ring 310 is also fixed to the upper surface of the fixed plate 304. A rubber scraper 311 is also fixed to the outside of the fixing ring 310. The scraper 311 contacts the inner wall of the mold cavity 6 to form a sliding mechanism. The pad 4 is symmetrically distributed about the center line of the support plate 5. The size of the support plate 5 is larger than the size of the mold cavity 6. The mold cavity 6 is located directly below the pressure plate 309. When using this high-efficiency molding device for steel slag concrete bricks, such as Figures 1-7 As shown, firstly, the steel slag concrete raw material is injected into the cavity formed by the mold cavity 6 and the support plate 5 by manual operation or feeding mechanism. After the steel slag concrete raw material is injected, the vibration motor 307 is started and the first cylinder 301 is controlled to extend. The extension of the first cylinder 301 drives the movable plate 302, the fixed plate 304, the support rod 308 and the pressure plate 309 to move downward. When the pressure plate 309 moves down to contact the steel slag concrete raw material in the mold cavity 6, the vibration of the vibration motor 307 can cause the fixed plate 304, the support rod 308 and the pressure plate 309 to vibrate. With the continuous extension of the first cylinder 301, the pressure plate 309 can vibrate the steel slag concrete raw material in the mold cavity 6, thereby allowing the steel slag concrete raw material in the mold cavity 6 to be quickly vented. Furthermore, during the process of the first cylinder 301 extending and driving the pressure plate 309 downward, when the pressure plate 309 contacts the steel slag concrete material in the mold cavity 6, the steel slag concrete material in the mold cavity 6 will generate a certain resistance to the downward movement of the pressure plate 309. At this time, through the continuous extension of the first cylinder 301, the movable plate 302 moves downward relative to the fixed plate 304. With the sliding guide action between the movable plate 302 and the vertical rod 303, the stability of the downward movement of the movable plate 302 can be ensured. At this time, the first spring 305 is compressed. That is, in the early stage of the contact between the pressure plate 309 and the steel slag concrete material in the mold cavity 6, through the vibration action of the vibration motor 307 and the flexible support action of the first spring 305 between the movable plate 302 and the fixed plate 304, the initial compaction and rapid degassing of the steel slag concrete material in the mold cavity 6 can be achieved. During the continuous extension of the first cylinder 301, the movable plate 302 moves downward relative to the fixed plate 304. The movable plate 302 moves continuously relative to the fixed plate 304. As the movable plate 302 moves downward, the positioning rod 306 can be moved towards the fixed plate 304 simultaneously. When the positioning rod 306 contacts the welding wire of the fixed plate 304, the flexible support formed between the movable plate 302 and the fixed plate 304 by the first spring 305 is transformed into a rigid support formed between the movable plate 302 and the fixed plate 304 by the positioning rod 306. At this time, the first cylinder 301 continues to extend, which can make the movable plate 302, the fixed plate 304 and the pressure plate 309 move downward again, thereby applying pressure to the initially formed steel slag concrete brick again to ensure that the steel slag concrete brick is uniform and dense inside. According to the above principle, the gas in the steel slag concrete raw material can be quickly removed by the initial flexible vibration and pressing. Combined with the subsequent vibration and secondary pressing, the production quality of steel slag concrete brick can be effectively guaranteed. The demolding mechanism 7 includes horizontal plates 701 symmetrically fixed on the fixed frame 2, and a second cylinder 702 fixed on the horizontal plate 701, with the output end of the second cylinder 702 fixed to the mold cavity 6. The horizontal plate 701 is slidably connected to the guide rod 703, which is fixed to the movable frame 704 located outside the mold cavity 6. A second spring 705 is fixed between the movable frame 704 and the horizontal plate 701. A fixing block 706 is also fixed to the lower end face of the movable frame 704, and a sloping groove 707 is provided on the fixing block 706. The sloping groove 707 is slidably connected to the slide rod 708, which is also slidably connected to the mold cavity 6. One end of the slide rod 708 is fixed to one end of the horizontal rod 709, and the other end of the horizontal rod 709 is fixed to the side plate 710. Furthermore, the side plate 710 and the vertical groove 716 are slidably connected, and the vertical groove 716 is opened on the side wall of the mold cavity 6; a piston head 711 is also fixed on the cross rod 709, and the piston head 711, the cross rod 709 and the cylinder 712 are slidably connected, and the cylinder 712 is fixed on the outside of the mold cavity 6. At the same time, a one-way air inlet valve and a one-way air outlet valve are installed on the cylinder 712. The cylinder 712 is connected to the air guide pipe 713 through the one-way air outlet valve, and the air guide pipe 713 is connected to the air guide groove 714. The air guide groove 714 is connected to the air guide channel 715. At the same time, the air guide channel 715 and the air guide groove 714 are both opened in the mold cavity 6. The air guide channel 715 is evenly distributed in the mold cavity 6, and the air guide channel 715 is connected to the vertical groove 716. The air guide channel 715 cooperates with the side plate 710 to achieve a seal. After the steel slag concrete bricks are formed, as Figures 1-7 As shown, at this time, by controlling the synchronous contraction of the first cylinder 301 and the second cylinder 702, when the second cylinder 702 contracts, it drives the mold cavity 6 to move upward so that the mold cavity 6 separates from the formed steel slag concrete brick. In the early stage of the contraction of the first cylinder 301, since the first spring 305 is in a contracted state when the steel slag concrete brick is pressed and formed, the rigid support between the movable plate 302 and the fixed plate 304 is transformed into a flexible support through the action of the first spring 305 during the initial contraction of the first cylinder 301. That is, in the initial stage of the synchronous contraction of the first cylinder 301 and the second cylinder 702, the rigid support between the movable plate 302 and the fixed plate 304 is transformed into a flexible support. Due to the elastic support of the first spring 305, the position of the pressure plate 309 remains unchanged. That is, when the second cylinder 702 drives the mold cavity 6 to move upward, the elastic action of the first spring 305 can cause the pressure plate 309 to exert a certain downward pressure on the formed steel slag concrete brick, thereby better separating the steel slag concrete brick from the mold cavity 6. At this time, the mold cavity 6 moves upward relative to the pressure plate 309. With the contact and sliding action between the scraper 311 and the inner wall of the mold cavity 6, the residual debris adhering to the inner wall of the mold cavity 6 can be cleaned, ensuring the cleanliness of the inner wall of the mold cavity 6 for subsequent production. During the upward movement of the mold cavity 6 driven by the second cylinder 702, the cylinder 712, crossbar 709, and slide bar 708 are simultaneously moved upward. At this time, due to the flexible support of the movable frame 704 by the second spring 705, the movable frame 704 does not move upward synchronously with the slide bar 708. That is, the slide bar 708 moves upward relative to the movable frame 704. Combined with the sliding action between the slide bar 708 and the inclined groove 707, the slide bar 708 is forced to move, thereby driving the crossbar 709 to move outward from the mold cavity 6. Through the movement of the crossbar 709, the side plate 710 can be moved synchronously, thus separating the side plate 710 from the formed steel slag concrete brick. This reduces the contact area between the inner wall of the mold cavity 6 and the steel slag concrete brick, and also relieves the side plate 710 from the air passage. The sealing function of channel 715, when the crossbar 709 moves, synchronously drives the piston head 711 to slide in the cylinder 712, so that the gas in the cylinder 712 enters the air guide groove 714 through the one-way air outlet valve and the air guide pipe 713, and enters the vertical groove 716 through the air guide channel 715. In this way, the gas can fill the space between the inner wall of the mold cavity 6 and the steel slag concrete brick. The filling of gas can not only break the negative pressure formed by the tight fit between the inner wall of the mold cavity 6 and the steel slag concrete brick, but also create fluid lubrication by synchronous gas flow, reducing the friction between the inner wall of the mold cavity 6 and the steel slag concrete brick. It can also provide a certain force to the steel slag concrete brick through airflow, better assisting the steel slag concrete brick to detach from the mold cavity 6, and ensuring the demolding quality of the steel slag concrete brick. During the sliding process of the slide rod 708 within the inclined groove 707, when the slide rod 708 slides to the uppermost end of the inclined groove 707, the demolding of the steel slag concrete brick from the mold cavity 6 is completed. The second cylinder 702 continues to retract, which can drive the mold cavity 6, slide rod 708, fixed block 706, and movable frame 704 to move upwards synchronously. Combined with the sliding guidance between the guide rod 703 and the horizontal plate 701, the stability of the movable frame 704's movement is ensured, allowing the height of the movable frame 704 to be higher than the upper surface of the steel slag concrete brick. This prevents the movable frame 704 from obstructing the unloading of the steel slag concrete brick. When unloading the formed steel slag concrete brick, a forklift can be used to simultaneously transfer the pallet 5 and the formed steel slag concrete brick, and the next pallet 5 can be manually replaced and placed on the pad 4 to begin the production of the next steel slag concrete brick.
