Description

Technical Field

[0001] The utility model relates to the technical field of alumina ceramic processing equipment, in particular to alumina ceramic pressing and forming equipment. Background Art

[0002] Alumina ceramics are a type of ceramic material with aluminum oxide (Al2O3) as the main component. They are used in thick-film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. Due to their superior performance, they are increasingly used in modern society.

[0003] The forming methods of alumina ceramic products include dry pressing, grouting, extrusion, cold isostatic pressing, injection, casting, hot pressing and hot isostatic pressing. For example, patent number CN202322496234.7 discloses an alumina ceramic pressing and forming device. This solution sets a spring between the lower mold and the movable plate, and can move the pressed alumina ceramic upward by the rebound force of the spring to facilitate material removal. However, this design method has certain defects and shortcomings. First, since the spring has a certain elastic force, and since the elastic force of the spring is used to achieve the elastic extension and unloading of the alumina ceramic, the elastic force must be large. Therefore, in the normal state, the movable plate is located on the upper inner side of the lower mold. This method is not convenient for loading the alumina ceramic raw material. When loading, it is necessary to press the movable plate downward to load the raw material normally. If the elastic force of the spring is small and the alumina ceramic cannot be ejected normally, it can be seen that the benefit of this solution in actual use is small and needs to be improved. Utility Model Content

[0004] (1) Technical problems solved

[0005] In response to the deficiencies in the prior art, the utility model provides an alumina ceramic pressing and forming device, which arranges a strong spring between the lower surface of a movable plate and the inner bottom of a lower die base, and fixes a pull rope on the lower surface of the movable plate, and the end of the pull rope is connected to a winding roller. When the raw materials are loaded, the movable plate is pulled downward by the pull rope. At this time, the strong spring is in a compressed state and does not affect the loading of the raw materials. When the pressed alumina ceramics need to be ejected, the winding roller rotates in the opposite direction, so that the movable plate is reset and moved upward under the action of the strong spring, and the alumina ceramics are ejected. This method does not affect the loading of the alumina ceramics, and can ensure the ejection effect, which is convenient for taking out the alumina ceramics, and solves the problem that the current device is inconvenient for loading raw materials.

[0017] 1. The utility model fixes and connects the springs distributed in an array between the lower surface of the movable plate and the inner bottom of the lower die base. The springs are strong springs. When in use, the movable plate can be driven to move up by the elastic extension of the springs, and then the pressed alumina ceramics are ejected. A pull rope is fixedly connected to the lower surface of the movable plate, and the end of the pull rope is connected to the winding roller of the winding component.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example

[0026] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an alumina ceramic pressing and molding device proposed in an embodiment of the present invention includes a base 1 and a processing table 2, including a main body 201 fixedly connected to the base 1, and a lower die base 203 is fixedly connected to the cavity 202 opened in the main body 201, and a movable plate 205 is slidably connected to the inner wall of the lower die base 203, a spring 208 is fixedly connected between the lower surface of the movable plate 205 and the inner bottom of the lower die base 203, and two symmetrically distributed pull ropes 204 are fixedly connected to the lower surface of the movable plate 205, and the pull ropes 204 extend to the bottom of the base 1 through the holes opened in the lower die base 203, the main body 201 and the base 1 respectively; a winding component 8 includes a protective frame 801 fixedly connected to the bottom of the base 1, and a rotating shaft 803 rotatably connected to the protective frame 801, a winding roller 802 is coaxially fixed on the rotating shaft 803, and the pull rope 204 is wound around the winding roller 802.

[0027] It should be noted that the processing table 2 is used for the press molding of alumina ceramics. The processing table 2 is composed of a main body 201, a lower die base 203, a movable plate 205, etc. The movable plate 205 is slidably connected to the inner side of the lower die base 203. A spring 208 is set between the lower surface of the movable plate 205 and the inner bottom of the lower die base 203. The spring 208 is a strong spring 208, which can realize the elastic extension of the movable plate 205, and then the pressed alumina ceramics are ejected. By fixing a pull rope 204 on the lower surface of the movable plate 205, the pull rope 204 can be used to pull the movable plate 205. When the alumina ceramic raw material needs to be loaded, the pull rope 204 is used. 04 Pull the movable plate 205 downward to expose the space above the movable plate 205, and then do not affect the loading of the alumina ceramic raw material inside the lower die base 203. During this process, the spring 208 is in a compressed state. When the alumina ceramic inside the lower die base 203 needs to be ejected, the tensioning effect of the pull rope 204 can be canceled. By installing a winding component 8 at the bottom of the base 1, the winding component 8 includes a protective frame 801, a rotating shaft 803, a winding roller 802, etc. The winding roller 802 can realize the winding and pulling of the pull rope 204, and then control the moving state of the movable plate 205. When the alumina ceramic needs to be ejected, the winding roller 802 cancels the winding effect of the pull rope 204.

[0028] like Figure 2 As shown, in some embodiments, the lower surface of the movable plate 205 is fixedly connected to a limiting rod 209 , and the limiting rod 209 is slidably connected to the limiting holes 207 correspondingly opened in the lower mold base 203 and the body 201 .

[0029] It should be noted that by fixing the limiting rod 209 on the lower surface of the movable plate 205 and slidingly connecting the limiting rod 209 to the limiting hole 207 of the lower mold base 203 and the main body 201, the telescopic limiting function of the movable plate 205 can be achieved.

[0030] like Figure 2 As shown, in some embodiments, both sides of the movable plate 205 are provided with protruding edges 206 .

[0031] It should be noted that the convex edge 206 contacts the lower die base 203 , increasing the contact surface between the two sides of the movable plate 205 and the lower die base 203 , thereby ensuring the telescopic stability of the movable plate 205 .

[0032] like Figure 3 and Figure 4 As shown, in some embodiments, one end of the rotating shaft 803 extends to the outside of the protective frame 801 and is fixed with a worm gear 804, and a motor 806 is installed at the bottom of the base 1, and a worm 805 is coaxially fixed to one side of the motor 806, and the worm 805 is engaged with the worm gear 804.

[0033] It should be noted that the arrangement of the worm wheel 804, the worm 805 and the motor 806 can control the rotation of the rotating shaft 803 and the winding roller 802 to realize the winding of the pull rope 204, and can also release the pull rope 204, and then adjust the elastic state of the movable plate 205. When it is necessary to load the alumina ceramic raw material, it is necessary to control the movable plate 205 to move downward. At this time, the movable plate 205 is pulled downward by the pull rope 204. During operation, the worm 805 is controlled to rotate by the motor 806, and the worm 805 and the worm wheel 806 are connected. The meshing relationship between 04 causes the rotating shaft 803 and the winding roller 802 to rotate, and then the pull rope 204 is wound, and the movable plate 205 is pulled down by the pull rope 204. At this time, the spring 208 is in a compressed state, and the alumina ceramic raw material is loaded on the inner side of the lower mold base 203. When the pressed alumina ceramic needs to be ejected, the motor 806 is controlled to rotate in the reverse direction, and the winding effect of the pull rope 204 is cancelled, so that the movable plate 205 is stretched under the action of the spring 208, and then the alumina ceramic is ejected.

[0034] like Figure 1 As shown, in some embodiments, support rods 3 are fixedly connected to the four corners of the upper surface of the base 1, and the upper end of the support rods 3 is fixedly connected to the top plate 4, a pneumatic cylinder 5 is installed on the top plate 4, a pressure plate 6 is provided at the bottom of the output shaft of the pneumatic cylinder 5, and the lower surface of the pressure plate 6 is fixedly connected to the upper mold base 7.

[0035] It should be noted that the pneumatic cylinder 5 can control the extension and contraction of the pressing plate 6 and the upper die base 7 , and the upper die base 7 cooperates with the lower die base 203 to achieve the press molding of the alumina ceramics.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
