Description

Technical Field

[0001] The utility model relates to the technical field of magnetic tile production, in particular to a wet-process magnet forming device with a double-side guiding and centering structure. Background Art

[0002] In the production process of wet magnet die-casting, after the amount of material delivered by the feeding system to the die-casting mold reaches the standard, a hydraulic press is needed to cooperate with the die-casting mold to die-cast the material. During the die-casting process, the material in the die-casting mold will discharge the moisture in the material.

[0003] At present, in order to quickly drain water and obtain magnetic tile products with better molding density, an upper (lower) top hydraulic press has been designed, such as Figure 1 As shown, the top-type hydraulic press is generally equipped with a top-pressing connecting plate on the lower telescopic oil cylinder, and a guide top-pressing block set through the lower base plate is provided on the top-pressing connecting plate. The guide top-pressing block pushes up the punch during the die-casting action to complete the die-casting of the magnet. However, since the guide top-pressing block needs to flexibly pass through the lower base plate top-pressing punch, in general designs, the assembly gap between the guide top-pressing block and the lower base plate is usually set larger. At the same time, since the lower telescopic oil cylinder only relies on the guide top-pressing block to guide on the same side of the top-pressing connecting plate when pressing, after long-term use, problems such as gap wear will occur, resulting in poor centering effect when the guide top-pressing block presses upward.

[0004] In order to solve the problem of poor centering effect between the guide column and the lower substrate, the inventor designed a wet magnet forming device with a double-sided guide centering structure, and thus proposed the present application. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0038] like Figures 2 to 5 As shown, this embodiment provides a wet-type magnet forming device with a double-sided guide centering structure, including a guide pressing block 6 and a pressing connecting plate 5, and a lower telescopic oil cylinder 1 with a pressing piston 11. The guide pressing block 6 is arranged on the top of the pressing connecting plate 5, and the pressing connecting plate 5 is arranged on the top of the pressing piston 11. It also includes at least one guide assembly 8 vertically arranged on the pressing connecting plate 5, and a guide base plate 9 fixedly connected to the lower telescopic oil cylinder 1:

[0039] The guide assembly 8 and the guide pressing block 6 are respectively arranged on both sides of the pressing connecting plate 5;

[0040] The guide base plate 9 is arranged parallel to the pressing connecting plate 5 and is located below the pressing connecting plate 5 .

[0041] In this embodiment, by providing a guide base plate 9 and a guide assembly 8, and by disposing the guide assembly 8 and the guide pressing block 6 on either side of the pressing connecting plate 5, guides are formed on both sides of the pressing connecting plate 5 when the pressing piston 11 of the lower telescopic oil cylinder 1 is driven. This improves the centering effect, reduces wear, and makes the equipment more precise and durable.

[0042] Therefore, the core concept of this application is to achieve a guiding effect on both sides of the top-pressing connecting plate 5, improve the centering effect, centering accuracy and effect, ensure that the top-pressing connecting plate 5 is always in a horizontal state when pressing the guiding top-pressing block 6, reduce equipment wear, improve equipment life and accuracy, ensure the uniformity of force between the upper mold and the lower mold of the die-casting mold, and ensure the quality of the magnet product.

[0043] Specifically, in this embodiment, refer to Figures 2 to 5 As shown, the guide assembly 8 includes a guide rod 81 extending vertically through the guide base plate 9. The axis of the guide rod 81 is parallel to the axis of the pressing piston 11. The guide rod 81 extends vertically through the guide base plate 9. The guide base plate 9 is fixedly connected to the lower telescopic cylinder 1. Therefore, when the lower telescopic cylinder 1 drives the pressing piston 11, the guide base plate 9 restricts the guide rod 81 to movement along its axis, thereby providing guidance.

[0044] Specifically, in this embodiment, refer to Figures 2 to 5 As shown, the guide assembly 8 further includes a guide sleeve 82 disposed on the guide base plate 9. The guide rod 81 is inserted into the guide sleeve 82 and slidably connected thereto. The guide sleeve 82 is detachably fixedly connected to the guide base plate 9. The provision of the guide sleeve 82 improves the guiding accuracy of the guide assembly 8 and the accuracy of the pressing piston 11 when driving the pressing connecting plate 5, ensuring that the pressing connecting plate 5 is always in a horizontal state. In addition, in this embodiment, the guide sleeve 82 is fixedly connected to the guide base plate 9 by bolts, which facilitates subsequent installation, replacement, and maintenance of the guide sleeve 82.

[0045] Specifically, in this embodiment, refer to Figures 2 to 5 As shown, the guide assembly 8 further includes a guide sleeve felt 83 and a felt pressing ring 84 mounted on the top of the guide sleeve 82.

[0046] The guide rod 81 vertically passes through the felt pressing ring 84, the guide sleeve felt 83 and the guide sleeve 82 in sequence from top to bottom. The felt pressing ring 84 and the guide sleeve felt 83 can play a certain sealing role, preventing the lubricating oil between the guide rod 81 and the guide sleeve 82 from being quickly carried out, minimizing the wear of the guide sleeve 82 and the guide rod 81, and ensuring the operating accuracy and life of the equipment.

[0047] In some optional embodiments, the technician may adopt the following setting of the guide assembly 8 as needed, wherein the guide assembly 8 includes a vertically arranged guide rod 81, the bottom of the guide rod 81 is fixedly connected to the guide rod 81, and the top of the guide rod 81 is set through the top pressure connecting plate 5.

[0048] In some optional embodiments, the guide assembly 8 also includes a guide sleeve 82 arranged at the bottom of the top pressure connecting plate 5, and the guide rod 81 is inserted into the guide sleeve 82 and slidably connected thereto, and the guide sleeve 82 is detachably fixedly connected to the top pressure connecting plate 5.

[0049] In some optional embodiments, the number of the guide assemblies 8 is at least three, and the three or more guide assemblies 8 are distributed along the circumference of the pressing piston 11. Providing three or more guide assemblies 8 can improve the guiding effect of the guide assemblies 8 and enhance the stability of the equipment during operation.

[0050] Specifically, in this embodiment, Figure 4 As shown, the number of the guide assemblies 8 is four;

[0051] The guide base plate 9 and the top pressure connecting plate 5 are both rectangular in shape, and the four guide components 8 are respectively arranged near the corners of the guide base plate 9 and the top pressure connecting plate 5. On the basis of improving the guiding effect of the guide component 8 and enhancing the stability of the equipment during operation, the size of the guide base plate 9 and the top pressure connecting plate 5 can be reduced to minimize the volume of the equipment.

[0052] Specifically, in this embodiment, Figure 2 and Figure 3 As shown, the top pressure connecting plate 5 includes a top block connecting plate 52 and a guide rod connecting plate 51 which are superimposed and fixed together;

[0053] The guide assembly 8 is detachably fixedly connected to the bottom of the guide rod connecting plate 51;

[0054] The guide push block 6 is detachably fixedly connected to the top of the push block connecting plate 52. In this embodiment, the top of the guide rod 81 of the guide assembly 8 is provided with an external thread section, and the guide rod 81 is detachably connected to the bottom of the guide rod connecting plate 51 through its external thread section, while the guide push block 6 is detachably connected to the top of the push block connecting plate 52 by bolts.

[0055] Specifically, in this embodiment, Figure 2 and Figure 3 As shown, it includes an upper telescopic oil cylinder 2 that is inverted and arranged just above the lower telescopic oil cylinder 1, and a horizontally arranged guide connecting plate 31 is connected to the output end of the upper telescopic oil cylinder 2;

[0056] It also includes a vertically arranged guide column 32, the upper telescopic oil cylinder 2 and the lower telescopic oil cylinder 1 are fixedly connected to the upper and lower parts of the guide column 32 respectively, and the guide connecting plate 31 is slidably connected to the guide column 32 along the vertical direction.

[0057] During operation, after the material is delivered to the position, the upper telescopic oil cylinder 2 is first started to drive the guide connecting plate 31, driving the magnetizing structure 4 and the upper mold at the bottom of the magnetizing structure 4 to move downward until they are close to the structure for installing the lower mold.

[0058] Then start the lower telescopic oil cylinder 1, which drives the top pressure connecting plate 5 to move upward by driving the piston, and drives the guide top pressure block 6 to move upward to press the lower mold, thereby causing the magnet to be die-cast. During this movement, the guide top pressure block 6 and the guide rod 81 of the guide assembly 8 respectively guide and limit from both sides of the top pressure connecting plate 5 to prevent the top pressure connecting plate 5 from tilting, ensuring the centering accuracy and effect between the guide top pressure block 6 and the lower base plate 7. After die-casting, the magnetization process is carried out using the magnetization structure 4, and then the product can be taken out.

[0059] In some embodiments, as Figure 6 As shown, it also includes an auxiliary guide rod 85 arranged on the top of the guide rod connecting plate 51. There are multiple auxiliary guide rods 85 and they are evenly distributed around the circumference of the guide top pressure block 6. The auxiliary guide rod 85 is vertically connected to the lower base plate for sliding. By setting the auxiliary guide rod 85, the accuracy and effect of the centering guide can be further improved.
