Description

Technical Field

[0001] This utility model relates to a lightweight and energy-saving mold box for a vibration molding machine, belonging to the technical field of vibration molding equipment. Background Technology

[0002] Vibration molding machines are mainly used in the production of carbon products such as prebaked anodes and electrodes. The mold box of the vibration molding machine is one of the forms of carbon product forming molds. The vibration molding machine uses vibration to form carbon products of a specified shape, such as anode carbon blocks, from the material inside the mold box. During carbon product processing, the bottom of the mold box contacts the lower template, and the top of the mold box needs to be sealed by a vacuum hood and vacuumed to remove fumes and air from the paste used to make carbon products, creating a certain degree of vacuum. The degree of vacuum plays an important role in the quality of carbon products, so ensuring the vacuum degree inside the mold box is particularly important.

[0003] In typical vibration molding machines, a gap exists between the bottom of the mold box and the lower template, resulting in inadequate sealing and insufficient vacuum to meet process requirements, thus affecting the quality of carbon products. For mold boxes with a chamfered bottom hinge, the chamfer rotates around the hinge axis to meet the requirements of vibration molding and demolding of carbon products. Because the chamfer needs to move flexibly, its presence makes leakage more likely, affecting the sealing effect between the mold box and the lower template.

[0004] The existing mold box has a sleeve surrounding it. The upper part of the sleeve is sealed to the middle part of the mold box, and the lower part can seal and contact the lower template. The sleeve does improve the sealing effect of the mold box during vacuuming. However, there is a certain gap between the sleeve and the mold box body. The outer dimensions of the sleeve are larger than those of the mold box, making the mold box more cumbersome and consuming vibration energy, resulting in energy waste during vibration. Furthermore, the mold box and sleeve are in a high-frequency vibration state during molding. The large size of the sleeve may cause slight deformation during vibration, which may affect the sealing effect. Therefore, the strength of the sleeve needs to be strengthened. However, the increased weight due to the strengthened sleeve further aggravates the consumption and waste of vibration energy. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a lightweight and energy-saving mold box for vibration molding machines.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A lightweight and energy-saving mold box for a vibration molding machine includes a box body, and a sealing structure is provided on the outer side of the bottom of the box body. The sealing structure includes an annular surrounding plate and a sealing ring. The upper part of the annular surrounding plate is sealed to the box body, and the bottom of the annular surrounding plate is provided with an annular positioning groove for positioning the sealing ring.

[0007] This invention features an annular surrounding plate on the outer side of the bottom of the mold box. The upper part of the annular surrounding plate is sealed to the mold box. The annular surrounding plate contains space for the chamfered body to move. When the mold box contacts the lower template, the sealing ring in the annular positioning groove at the bottom of the annular surrounding plate can seal against the lower template. The annular surrounding plate and the mold box together form a sealed molding space, enhancing the sealing effect of the mold box, filling the gap between the mold box and the lower template, blocking the path of external air into the mold box, and ensuring that the mold box can reach and maintain the required vacuum level during the vacuuming process, thereby guaranteeing the product quality of carbon products. This invention offers two advantages: firstly, a simple structure and excellent sealing effect; secondly, a significantly reduced size of the annular surrounding plate, especially in height, greatly reducing the weight of the mold box; and thirdly, it avoids the problem of increasing weight due to reinforcement in the original mold box structure to ensure strength. Both of these factors combined reduce the vibration weight of the mold box, thus achieving lightweighting of the mold box while maintaining a sealed vacuum, resulting in high efficiency and energy saving during vibration.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the box body includes a box body and multiple horizontal plates disposed on the box body, and the annular surrounding plate is sealed to the horizontal plate located at the bottom of the box body.

[0010] The advantages of adopting the above-mentioned further solution are that the annular surrounding plate is sealed to the horizontal plate located at the bottom of the box body, making welding easier. The annular surrounding plate is located on the outer side of the bottom of the mold box, ensuring a good seal, simplifying the overall structure of the box, and significantly reducing the outer perimeter and height dimensions of the annular surrounding plate compared to a nested box. This reduces the vibration weight of the mold box, avoids wasting vibration energy, and achieves high efficiency and energy saving.

[0011] Furthermore, the top wall of the annular enclosure is sealed to the bottommost horizontal plate.

[0012] The beneficial effects of adopting the above-mentioned further solution are that the top wall of the annular baffle is sealed to the horizontal plate, and the horizontal plate at the bottom of the box is connected to the top wall of the annular baffle. The horizontal plate can directly apply force to the annular baffle located below it. The annular baffle is subjected to pressure from the top horizontal plate rather than the lateral force of the horizontal plate, resulting in a better force application effect. The annular baffle is more stable when vibrating, further ensuring the sealing effect between the sealing ring at the bottom of the annular baffle and the lower template, and ensuring that the vacuum degree in the mold box can meet the molding requirements of carbon products.

[0013] Furthermore, multiple vertical stiffeners are provided between adjacent horizontal plates.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the horizontal plates and vertical stiffeners on the main body of the box work together to enhance the structural strength of the main body of the box, effectively resist the vibration and stress generated during the vibration molding process, and reduce the deformation of the main body of the box; at the same time, it will not increase the weight of the mold box excessively, reduce the vibration weight of the mold box, and meet the requirements of high efficiency and energy saving of the mold box.

[0015] Furthermore, the inner wall of the annular enclosure is sealed to the lowermost horizontal plate, and the bottom of the vertical stiffener located at the lowermost side of the box body acts on the top of the annular enclosure.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the existing mold box has an outer sleeve, and the force on the sleeve comes from the side force of the mold box. The force application effect on the sleeve is not good, affecting the sealing fit between the sleeve and the lower template. The bottom of the vertical stiffener plate located at the bottom of the mold box body directly acts on the top of the annular partition plate. The force of the mold box directly presses on the annular partition plate located below it. The annular partition plate bears the pressure from the vertical stiffener plate at its top. The annular partition plate is more stable when vibrating, and the sealing fit between the sealing ring at the bottom of the annular partition plate and the lower template is better. The sealing connection between the inner wall of the annular partition plate and the bottom horizontal plate of the mold box body, as well as the direct force application from the bottom of the vertical stiffener plate to the top of the annular partition plate, make the entire mold box form a closed and stable force system during vibration molding, further improving the reliability and sealing performance of the mold box during operation.

[0017] Furthermore, the box has a square structure.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the square mold box can meet the molding requirements of square carbon products such as anode carbon blocks. During the vibration molding process, the square mold box is subjected to uniform and stable force, which is conducive to the molding quality of carbon products.

[0019] Furthermore, the annular enclosure includes sealing enclosures respectively disposed on the four sides of the box body of the square structure, and adjacent sealing enclosures are sealed together.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the mold box has a square structure, and the annular surrounding plate includes sealing plates located on the four sides. The inner wall or top wall of the sealing plate is sealed to the horizontal plate, and the adjacent sealing plates are sealed to each other, ensuring the sealing performance of the mold box. This ensures that the vacuum degree inside the mold box can meet the requirements of the carbon product molding process, and avoids external air entering the mold box during the vacuuming process, which would affect the molding of the carbon product.

[0021] Furthermore, the corners of the annular positioning groove are transitioned by a circular arc structure.

[0022] The beneficial effects of adopting the above-mentioned further solution are that the arc structure transition makes the sealing ring smoother during installation, reducing the installation difficulty; it allows the sealing ring to smoothly transition at the corners, ensuring the sealing effect of the sealing ring, improving the overall sealing performance of the mold box, effectively preventing air intrusion during vibration molding, meeting the vacuum sealing requirements, and ensuring the molding quality of carbon products.

[0023] Furthermore, the vertical stiffeners at the top of the horizontal plate are staggered from those at the bottom of the horizontal plate.

[0024] The beneficial effect of adopting the above-mentioned further scheme is that the arrangement of the vertical stiffeners at the top and bottom of the horizontal plate can be the same, or they can be staggered; the staggered arrangement of the upper and lower vertical stiffeners can enhance the overall structural strength of the mold box, making the force on each part of the mold box more uniform when it vibrates, and improving the service life and stability of the mold box.

[0025] Furthermore, a chamfered body is hinged to the bottom of the box, and the chamfered body is connected to the box via a hinge shaft.

[0026] The beneficial effect of adopting the above-mentioned further solution is that the chamfered body can rotate flexibly by connecting to the box body through the hinge shaft, and the chamfered body can move within the internal space enclosed by the annular partition plate, which meets the requirements of carbon product molding and carbon product demolding in the mold box.

Detailed Implementation

[0028] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0029] Example 1, such as Figures 1-7 As shown, a lightweight and energy-saving mold box for a vibration molding machine includes a box body 1. A sealing structure is provided on the outer side of the bottom of the box body 1. The sealing structure includes an annular surrounding plate 2 and a sealing ring 7. The upper part of the annular surrounding plate 2 is sealed to the box body 1, and the bottom of the annular surrounding plate 2 is provided with an annular positioning groove 3 for positioning the sealing ring 7.

[0030] The housing 1 includes a main body and multiple horizontal plates 5 disposed on the main body. The annular surrounding plate 2 is sealed to the horizontal plate 5 located at the bottom of the main body. The sealed connection between the annular surrounding plate 2 and the horizontal plate 5 at the bottom of the main body facilitates easier welding. The annular surrounding plate 2 is located on the outer side of the bottom of the housing 1, ensuring a good seal, simplifying the overall structure of the housing 1, and significantly reducing the outer dimensions and height of the annular surrounding plate 2 compared to a nested housing. This reduces the vibration weight of the mold box, avoids wasting vibration energy, and achieves high efficiency and energy saving. It also reduces the impact of vibration deformation on sealing performance, improving the service life and reliability of the mold box.

[0031] Multiple vertical stiffeners 6 are provided between adjacent horizontal plates 5. The horizontal plates 5 and vertical stiffeners 6 on the main body of the mold cooperate with each other to enhance the structural strength of the main body of the mold, effectively resist the vibration and stress generated during the vibration molding process, and reduce the deformation of the main body of the mold; at the same time, it will not increase the weight of the mold excessively, reduce the vibration weight of the mold, avoid the waste of vibration energy, and meet the requirements of high efficiency and energy saving of the mold.

[0032] The inner wall of the annular surrounding plate 2 is sealed to the bottommost horizontal plate 5, and the bottom of the vertical stiffener 6 located at the bottommost side of the main body of the box acts on the top of the annular surrounding plate 2. Existing mold boxes have an outer casing, and the force on the casing comes from the lateral force of the mold box, resulting in poor force application and affecting the sealing fit between the casing and the lower template. In this invention, the bottom of the vertical stiffener 6 located at the bottommost side of the main body of the mold box acts directly on the top of the annular surrounding plate 2. The force of the mold box directly presses onto the annular surrounding plate 2, and the annular surrounding plate 2 bears the pressure from the vertical stiffener 6 at its top. The annular surrounding plate 2 is more stable during vibration, and the sealing fit between the sealing ring 7 at the bottom of the annular surrounding plate 2 and the lower template is better. The sealed connection between the inner wall of the annular surrounding plate 2 and the bottommost horizontal plate 5 of the main body of the box, as well as the direct force application of the bottom of the vertical stiffener 6 on the top of the annular surrounding plate 2, creates a closed and stable force system for the entire mold box during vibration molding, further improving the reliability and sealing performance of the mold box during operation.

[0033] The box 1 has a square structure. The square mold box can meet the molding requirements of square carbon products such as anode carbon blocks. During the vibration molding process, the square mold box is subjected to uniform and stable force, which is beneficial to the molding quality of carbon products.

[0034] The annular enclosure 2 includes sealing enclosures respectively disposed on the four sides of the square-structured box 1, with adjacent sealing enclosures being sealed together. The box 1 of the mold box has a square structure, and the annular enclosure 2 includes sealing enclosures located on the four sides. The inner wall or top wall of the sealing enclosure is sealed together with the horizontal plate 5, and adjacent sealing enclosures are sealed together to ensure the airtightness of the mold box. This ensures that the vacuum level inside the mold box meets the requirements of the carbon product molding process, preventing external air from entering the mold box during the vacuuming process and affecting the molding of the carbon products.

[0035] The corner of the annular positioning groove 3 is transitioned by a circular arc structure 4. The circular arc structure 4 makes the installation of the sealing ring 7 smoother and reduces the installation difficulty; it also allows the sealing ring 7 to smoothly transition at the corner, ensuring the sealing effect of the sealing ring 7, improving the overall sealing performance of the mold box, effectively preventing air intrusion during vibration molding, meeting the vacuum sealing requirements, and ensuring the molding quality of carbon products.

[0036] The vertical stiffening plates 6 located at the top of the horizontal plate 5 are staggered from those located at the bottom of the horizontal plate 5. The arrangement of the vertical stiffening plates 6 at the top and bottom of the horizontal plate 5 can be the same, or they can be staggered. The staggered arrangement of the upper and lower vertical stiffening plates 6 can enhance the overall structural strength of the mold box, making the stress on each part of the mold box more uniform when vibrating, and improving the service life and stability of the mold box.

[0037] A chamfered body 8 is hinged to the bottom of the housing 1, and the chamfered body 8 is connected to the housing 1 via a hinge shaft 9. The chamfered body 8 can rotate flexibly when connected to the housing 1 via the hinge shaft 9, and can move within the internal space enclosed by the annular partition 2, thus meeting the requirements for molding carbon products in the mold box and demolding carbon products.

[0038] The bottom of the chamfered body 8 is a flat structure, and the inner wall of the chamfered body 8 is an arc-shaped structure. The flat bottom of the chamfered body 8 ensures its stability during placement and guarantees stability during the vibration molding process; while the arc-shaped inner wall of the chamfered body 8 allows the material to be fully filled and shaped in the mold box during vibration, meeting the molding requirements of carbon products.

[0039] In Example 2, the top wall of the annular surrounding plate 2 is sealed to the bottommost horizontal plate 5. The top wall of the annular surrounding plate 2 is sealed to the horizontal plate 5, and the bottommost horizontal plate 5 of the housing 1 is connected to the top wall of the annular surrounding plate 2. This horizontal plate 5 can directly apply force to the annular surrounding plate 2 below it. The annular surrounding plate 2 is subjected to pressure from the top horizontal plate 5 rather than the lateral force of the horizontal plate 5, resulting in a better force application effect and greater stability during vibration. This further ensures the sealing effect between the sealing ring 7 at the bottom of the annular surrounding plate 2 and the lower template, ensuring that the vacuum level inside the mold box meets the requirements for carbon product molding. The remaining structure is the same as in Example 1, and therefore will not be described further here.

[0040] This invention features an annular surrounding plate 2 on the outer side of the bottom of the housing 1. The upper part of the annular surrounding plate 2 is sealed to the horizontal plate 5 at the bottom of the housing 1. The small height and outer dimensions of the annular surrounding plate 2 reduce the impact of vibration deformation on the sealing performance, reduce the vibration weight of the mold box, and avoid the waste of vibration energy caused by the increased vibration weight due to the original structure. This achieves a high-efficiency and energy-saving effect during the vibration process. During the carbon product molding and demolding process, the chamfered body 8 can move within the space of the annular surrounding plate 2 without hindering the demolding of the molded carbon product. At the same time, it ensures the sealing ring 7 at the bottom of the annular surrounding plate 2 can seal with the lower template. The vertical stiffener 6 or the horizontal plate 5 directly applies force to the top of the annular surrounding plate 2, ensuring a stable sealing fit between the annular surrounding plate 2 and the lower template during the vibration molding process. This enhances the sealing effect of the mold box, blocks the path of external air into the housing 1, and ensures that the mold box can reach and maintain the required vacuum level during the vacuuming process, thereby guaranteeing the product quality of the carbon product.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
