Description

Technical Field

[0001] This utility model relates to the field of permeable brick preparation technology, specifically a vibration pressure molding die for preparing permeable bricks from waste sand. Background Technology

[0002] Vibration-press molding of permeable bricks from waste sand is a molding process that combines vibration and pressure. It is mainly used to process industrial waste sand into permeable bricks after mixing it with other raw materials. The vibration-press molding machine uses vibration to make the mixed raw materials evenly distributed in the mold, eliminating gaps between particles and improving density. Pressure is applied at the same time or after vibration to further compress the raw materials and enhance the strength and structural stability of the brick.

[0003] Vibration compression molding is a tool that uses the combined action of vibration and pressure to compact industrial waste sand and other raw materials into a specific shape. Its core function is to eliminate internal friction in the material through vibration, causing the particles to rearrange and fill the mold space, and then further increase the density and strength of the product through pressure.

The rotating sleeve drives the threaded tube to rotate, which in turn drives the movable ring to rise and fall, thereby controlling the movement direction and position of the forming thickness adjustment plate. When it is necessary to reduce the forming thickness, the movable ring rises and pushes the adjustment plate to move upward, reducing the top space of the forming container cavity. When it is necessary to increase the thickness, the movable ring descends to release the support, and the first spring drives the connecting plate and the ejector rod to move downward, causing the adjustment plate to reset. This mechanical linkage structure does not require an additional power source, is simple to operate, and responds quickly. It can adapt to the production needs of permeable bricks of different specifications. At the same time, the design of the circular groove at the bottom of the adjustment plate and the ejector plate ensures uniform force during the adjustment process, avoiding the problem of mold deformation or uneven material distribution caused by local stress concentration, and significantly improving the stability of forming quality.

[0021] 2. This utility model achieves rapid demolding of permeable bricks through the coordinated action of the ejector rod, pull rod, and spring. Workers only need to pull the pull rod upwards to move the connecting plate and ejector rod, allowing the ejector plate to directly push out the formed permeable bricks. This eliminates the tedious operation of traditional manual hammering or complex mechanical devices, significantly shortening demolding time and reducing labor intensity. Furthermore, the double-sealing design of the sealing plate and sealing strip effectively prevents material spillage or seal failure during vibration and pressurization, ensuring that the molding pressure is evenly transmitted to the inside of the material, improving the density and strength of the green body. The cooperation between the limiting rod and the second spring further enhances the stability of the sealing plate, avoiding displacement deviation caused by vibration, thereby ensuring the continuity of the production process and the yield rate. These designs collectively improve the automation level and production efficiency of the equipment, while reducing energy consumption and maintenance costs. Attached Figure Description

[0030] Furthermore, a rotating sleeve 114 is fixedly sleeved at the bottom of the threaded tube 113, and a movable ring 115 is fixedly sleeved at the top of the threaded tube 113. The movable ring 115 is rotatably connected to the bottom of the forming thickness adjustment plate 103 to drive it.

[0031] Furthermore, the upper mold 2 includes a pressure head 201, and a sealing plate 202 is movably sleeved on the surface of the pressure head 201. The sealing plate 202 is installed on the top of the permeable brick forming container 101.

[0032] Furthermore, the top of the forming thickness adjustment plate 103 is provided with a circular groove for receiving the circular ejector plate 104.

[0033] Furthermore, a connecting plate 109 is fixedly connected to the bottom of the ejector rod 111, and pull rods 105 are fixedly connected to the left and right sides of the top of the connecting plate 109.

[0034] Furthermore, a sliding sleeve 106 is movably sleeved on the surface of the pull rod 105. The sliding sleeve 106 is fixedly installed on the surface of the permeable brick forming container 101. A first spring 107 is movably sleeved on the surface of the pull rod 105. The first spring 107 is located on the side opposite to the sliding sleeve 106 and the connecting plate 109.

[0035] Furthermore, the bottom of the permeable brick forming container 101 is fixedly connected to the four corners of the bottom with a first mounting rod 108, and the bottom of the first mounting rod 108 is fixedly connected to a first mounting plate 110.

[0036] Furthermore, lifting plates 207 are fixedly connected to the front and rear sides of the top of the pressure head 201. Limiting rods 206 are movably connected to the lifting plates 207. The bottom of the limiting rods 206 is fixedly connected to the top of the sealing plate 202. A second spring 205 is movably sleeved on the surface of the limiting rods 206. The second spring 205 is located on the opposite side of the lifting plates 207 and the sealing plate 202.

[0037] Furthermore, a second mounting rod 209 is fixedly connected to the four corners of the top of the pressure head 201, and a second mounting plate 208 is fixedly connected to the top of the second mounting rod 209.

[0038] Furthermore, positioning seats 203 are fixedly connected to the front and rear sides of the sealing plate 202. The positioning seats 203 are movably connected to the surface of the permeable brick forming container 101. Positioning grooves 204 are provided on the positioning seats 203. Positioning pins 112 are fixedly connected to the front and rear sides of the permeable brick forming container 101.

[0039] Furthermore, a sealing strip 210 is fixedly connected to the bottom of the sealing plate 202, and a sealing groove 102 is opened on the top of the permeable brick forming container 101. The sealing strip 210 is located inside the sealing groove 102 and is movably connected to it.

[0040] When the molding thickness of the permeable brick needs to be adjusted, the rotating sleeve 114 drives the threaded tube 113 to rotate. During the rotation of the threaded tube 113, it rises and falls within the cavity of the permeable brick molding container 101, and simultaneously drives the movable ring 115 to rotate. The movable ring 115 rotates at the bottom of the molding thickness adjustment plate 103. When the position of the movable ring 115 rises, it drives the molding thickness adjustment plate 103 to move upward, reducing the space at the top of the cavity of the permeable brick molding container 101, thereby reducing the molding thickness of the permeable brick. When the position of the movable ring 115 falls, the support for the bottom of the molding thickness adjustment plate 103 is removed. At this time, the first spring 107 drives the connecting plate 109 and the ejector rod 111 to move downward. The ejector rod 111 drives the molding thickness adjustment plate 103 to move downward through the circular ejector plate 104, increasing the space at the top of the cavity of the permeable brick molding container 101, thereby increasing the molding thickness of the permeable brick.

[0041] When it is necessary to demold the permeable bricks after molding, the worker pulls the pull rod 105 upwards. The pull rod 105 drives the connecting plate 109 and the ejector rod 111 to move upwards. The ejector rod 111 drives the circular ejector plate 104 to move upwards. The circular ejector plate 104 pushes out the permeable bricks on top of the molding thickness adjustment plate 103 to achieve rapid demolding.

[0042] When forming permeable bricks, waste sand and other raw materials are mixed and poured into the top of the inner cavity of the permeable brick forming container 101. The forming thickness adjustment plate 103 supports the bottom of the raw material. Then, the upper mold 2 is moved downward by the vibration and pressure forming machine. During the operation of the upper mold 2, the second mounting plate 208 and the second mounting rod 209 drive the pressure head 201 downward. The pressure head 201 transmits pressure to the sealing plate 202 through the second spring 205, so that the sealing plate 202 fits tightly against the permeable brick forming container 101. After the fit is completed, the sealing strip 210 enters the sealing groove 102 to seal the connection. The positioning pin 112 enters the positioning groove 204 to prevent positioning deviation. Then, the pressure head 201 slides inside the sealing plate 202 and continues to apply downward pressure to compress and form the raw material, so that the raw material forms the permeable brick blank at the top of the inner cavity of the permeable brick forming container 101.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
