Description
Technical Field
[0001] The utility model relates to the technical field of molding machines, in particular to a small-sized press machine used in laboratories. Background Art
[0002] In laboratory environments, traditional small vibration presses are widely used to prepare small-sized samples for testing due to their small size and simple operation. However, the stability of small presses has always been a key factor restricting their application effect. Due to their small size, their overall structure is often relatively simple, which leads to shaking during the vibration pressing process. This shaking not only affects the accuracy of the pressing process, but more importantly, it will lead to poor material pressing effect.
[0003] During the shaking process of a small press, the force applied by the vibrating platen is easily offset, which can easily lead to uneven force on the material. When the material is unevenly stressed, the distribution and arrangement of the particles inside it will be affected, and it will not be able to form an ideal tight structure. This directly leads to various defects on the surface of the material after pressing, such as unevenness, depressions or protrusions. Utility Model Content

[0028] Combine the following Figures 1 to 3 , describing a small laboratory press according to an embodiment of the utility model.
[0029] A small laboratory press comprises, from bottom to top, a base 1, a mold, a limit assembly 2 and a vibration pressing assembly 3;
[0030] The base 1 is vertically provided with a guide assembly 4 and a lifting power member 5. The lifting end of the lifting power member 5 is fixedly connected to the vibration and pressure assembly 3. The lifting power member 5 is used to lift the vibration and pressure assembly 3 in the vertical direction. The guide assembly 4 is used to limit the vibration and pressure assembly 3 to move in the vertical direction. The vibration and pressure end of the vibration and pressure assembly 3 moves vertically to vibrate and press the mold.
[0031] The limiting component 2 is arranged directly below the vibration and pressure component 3. The limiting component 2 is at least two L-shaped plates 21. The two L-shaped plates 21 are distributed corresponding to the two symmetrical side walls of the mold, and at least two side walls of the mold are in contact with the opposite L-shaped plates 21.
[0032] In this solution, a small laboratory press is used to place the material on the mold, and then the limit component 2 can limit the position of the mold on the base 1 to prevent the mold from shaking during the pressing process, resulting in poor material pressing effect. The lifting power part 5 can lift the vibration pressing component 3 and adjust the distance between the vibration pressing component 3 and the mold so that the vibration pressing end of the vibration pressing component 3 can abut the mold to ensure that the vibration pressing component 3 can press the material into shape.
[0033] Among them, a guide component 4 is arranged on the base 1, and the guide component 4 can limit the vibration-pressing component 3 to move only in the vertical direction, effectively avoiding the position displacement of the vibration-pressing component 3 during the vibration-pressing process, and ensuring that the vibration-pressing end of the vibration-pressing component 3 can more accurately press the material on the mold.
[0034] In addition, the guide component 4 can also reduce the shaking and vibration of the vibration pressing component 3 during the vibration process, improve the stability of the small press of this solution, and solve the problem that the traditional small press has poor stability and is prone to shaking, resulting in poor material pressing effect.
[0035] The vibration and pressure assembly 3 includes a vibration and pressure power piece 31, a mounting plate 32 and a vibration pressure plate 33; the vibration and pressure power piece 31 is mounted on the top of the mounting plate 32, the output end of the vibration and pressure power piece 31 passes through the bottom of the mounting plate 32 and is fixedly connected to the vibration pressure plate 33, and the vibration pressure plate 33 is movable to vibrate and press the mold;
[0036] The lifting end of the lifting power member 5 is fixedly connected to the mounting plate 32 , and the mounting plate 32 is connected to the guide assembly 4 , and the guide assembly 4 is used to limit the moving direction of the mounting plate 32 .
[0037] The output end of the vibration-pressure power member 31 is fixedly connected to the vibration pressing plate 33, so that the vibration-pressure power member 31 can drive the vibration pressing plate 33 to vibrate and press the material, thereby preparing a plate with a dense structure.
[0038] Among them, the mounting plate 32 is connected to the guide assembly 4, and the guide assembly 4 can limit the movement direction of the mounting plate 32, so that the mounting plate 32 drives the vibration and pressure power part 31 and the vibration pressure plate 33 to move in the vertical direction, thereby reducing the deviation of the vibration pressure plate 33 during the vibration and pressure process, resulting in uneven surface, depression or protrusion of the material due to uneven force, which seriously affects the pressing effect of the material.
[0039] The guide assembly 4 includes a plurality of guide posts 41 , which are vertically mounted on the base 1 . The plurality of guide posts 41 are arranged in a matrix, and the mounting plate 32 is slidably connected to the plurality of guide posts 41 .
[0040] The guide column 41 not only plays a supporting and positioning role, but also limits the range of movement of the mounting plate 32 so that it can only move in the vertical direction and cannot deviate in other directions.
[0041] Since the vibration-pressing power member 31 is installed on the mounting plate 32, the vibration-pressing power member 31 drives the vibration pressing plate 33 to more accurately press the material on the mold, avoiding the problem of uneven force on the material due to position offset. At the same time, the presence of multiple guide columns 41 can also reduce the shaking and vibration of the mounting plate 32 during the vibration process, further improving the pressing quality of the plate and extending the service life of the mold.
[0042] The limiting assembly 2 is composed of three L-shaped plates 21 . The three L-shaped plates 21 are distributed corresponding to the three side walls of the mold. The three side walls of the mold are all in contact with the corresponding L-shaped plates 21 .
[0043] Reference Figure 3 , the L-shaped plate 21 is installed on the base 1, and the three L-shaped plates 21 surround and form a U-shaped accommodation space. The two opposite L-shaped plates 21 can guide the movement of the mold, so that the mold slides into the accommodation space under the guidance of the two opposite L-shaped plates 21. At this time, the three L-shaped plates 21 are respectively in contact with the three side walls of the mold, effectively avoiding the position deviation of the mold during the vibration and pressing process, and reducing the defects such as burrs on the plate.
[0044] The vertical end of the L-shaped plate 21 is vertically connected to the base 1, and the horizontal end of the L-shaped plate 21 is parallel to the base 1. The L-shaped member and the base 1 form a slide groove, and the slide groove is slidably connected to one side wall of the mold.
[0045] In addition, in order to prevent the mold from shaking with the rise and fall of the vibrating press plate 33, resulting in poor pressing quality of the plate, the L-shaped part is installed upside down so that the L-shaped part and the base 1 form a slide groove. The slide groove can not only guide the movement direction of the mold so that the mold can slide horizontally into the accommodating space, but also ensure that the horizontal end of the L-shaped part can abut the top of the mold, limiting the movement of the mold in the vertical direction, thereby further improving the pressing effect of the plate.
[0046] The base 1 is provided with a void avoidance groove 11 , and a corner code 12 is provided on one side of the base 1 close to the void avoidance groove 11 . The corner code 12 connects the base 1 and the lifting power member 5 , and the installation end of the lifting power member 5 is located in the void avoidance groove 11 .
[0047] The lifting power member 5 is installed on the base 1 through the angle code 12, which is simple and quick to install, reducing the difficulty and complexity of the installation and maintenance of the lifting power member 5. The design of the air avoidance groove 11 can effectively utilize the internal space of the base 1, so that the installation part of the lifting power member 5 can be embedded therein, effectively reducing the influence of external factors on the operation of the lifting power member 5, such as dust, impurities or collisions with other objects.
[0048] There are two lifting power members 5 , and the two lifting power members 5 are arranged opposite to each other.
[0049] It is worth noting that the lifting power member 5 is a gas cylinder or an oil cylinder. The two lifting power members 5 can provide a more stable lifting force, which can ensure that the mounting plate 32 is evenly stressed during the lifting process, and prevent the mounting plate 32 from shaking or tilting during the lifting process. This balance helps to extend the service life of the mounting plate 32 and keep it in good working condition.
[0050] When one of the lifting power components 32 breaks down or fails, the other lifting power component 32 can still provide the necessary lifting force, thereby improving the reliability of the entire system and preventing the mounting plate 32 from losses and risks caused by unexpected events.
[0051] The vibration-pressure assembly 3 further includes a limit plate. The output end of the vibration-pressure power member 31 is fixedly sleeved with a limit plate 34 , and the limit plates 34 are slidably connected to a plurality of guide pillars 41 .
[0052] The limit plate 34 and the guide column 41 are slidably connected, so that the guide column 41 can limit the range of movement of the limit plate 34, so that the limit plate 34 can only move in the vertical direction. Since the limit plate 34 is fixedly sleeved on the output end of the vibration-pressure power member 31, the range of movement of the vibration-pressure power member 31 can be limited, so that the vibration-pressure power member 31 and the vibration pressure plate 33 always move in the vertical direction, ensuring that the mold is evenly stressed during the pressing process, and improving the pressing quality of the plate.
[0053] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
