Automatic defoaming type vacuum pressing cavity structure is a key equipment component applied in the field of industrial manufacturing. Its core function is to press workpieces in a vacuum environment and eliminate bubbles generated during the pressing process through an automated mechanism to ensure product quality.

[0003] During the pressing process, the workers will use a clamp to position the object to be pressed, and then use a pressing plate to press the object. If there are air bubbles in the object during the pressing process, the workers will use a device to make the object vibrate locally to remove the air bubbles.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3This utility model provides an embodiment of an automatic defoaming type vacuum pressing cavity structure, including a worktable 1. A slide rail 3 is provided at the top of the worktable 1. Through externally controlled electric slide rail 3, a movable plate 4 can be moved to the area directly below a fixed frame 6. A bracket 2 is fixedly connected to the top of the worktable 1. An electric telescopic rod 5 is provided on the inner wall of the bracket 2. The electric telescopic rod 5 is a mechanical device that achieves telescopic movement of the rod body by being driven by an electric motor. A fixed frame 6 is fixedly connected to the movable end of the electric telescopic rod 5. The fixed frame 6 is connected to an external vacuum pump through a pipe. By evacuating air through the vacuum pump, a vacuum environment can be created inside the fixed frame 6. A hydraulic rod 7 is provided on the inner wall of the fixed frame 6. The hydraulic rod 7 is a mechanical device that achieves linear reciprocating motion using the principle of hydraulic transmission. A pressing plate 8 is fixedly connected to the movable end of the hydraulic rod 7. A gasket 15 is inserted into the inner wall of the pressing plate 8. The gasket 15 protects the pressed object and prevents damage caused by excessive force. A movable plate 4 is slidably connected to the outer wall of the slide rail 3. A trapezoidal block 9 is elastically connected to the inner wall of the rear end of the movable plate 4 via a movable spring 10. When the trapezoidal block 9 moves backward, the movable spring 10 is compressed. When resetting, the elastic force of the movable spring 10 carries the trapezoidal block 9 back to its original position. A groove is provided on the side wall of the trapezoidal block 9. A positioning plate 11 is slidably connected in the groove. When the trapezoidal block 9 presses the positioning plate 11, the positioning plate 11 can move left and right. An adjustment mechanism is provided at the top of the trapezoidal block 9. A disassembly assembly is provided on the inner wall of the pressing plate 8. The adjustment mechanism includes a triangular block 12, which is slidably connected to the top of the trapezoidal block 9. A slot corresponding to the triangular block 12 is provided on the trapezoidal block 9, allowing the triangular block 12 to move back and forth. An insert block 13 is elastically connected to the inner wall of the bottom end of the triangular block 12 via a movable spring 14. When the insert block 13 moves upward, the movable spring 14 is compressed. When resetting, the elastic force of the movable spring 14 carries the insert block 13 back to its original position.

[0036] Reference Figures 5-7 The disassembly assembly includes a slot 16, which is formed on the outer wall of the pressing plate 8. A baffle 18 is slidably connected to the inner wall of the slot 16. The slot 16 has a slot corresponding to the baffle 18, allowing the baffle 18 to move vertically. A locking block 17 is elastically connected to the inner wall of the left end of the baffle 18 via a positioning spring 19. When the locking block 17 moves to the left, the positioning spring 19 is compressed. When resetting, the elastic force of the positioning spring 19 carries the locking block 17 back to its original position. The outer wall of the baffle 18 contacts the outer wall of the gasket 15, and the baffle 18 acts as a shield and limiter for the gasket 15. The locking block 17 is slidably connected to the inner wall of the baffle 18. The baffle 18 has a slot corresponding to the locking block 17, allowing the locking block 17 to move left and right. The locking block 17 is engaged with the inner wall of the slot 16, which has two sets of slots corresponding to the locking block 17.

[0037] Reference Figures 2-4The trapezoidal block 9 is slidably connected to the inner wall of the movable plate 4. The movable plate 4 has a slot corresponding to the trapezoidal block 9, allowing the trapezoidal block 9 to move back and forth. The positioning plate 11 is slidably connected to the inner wall of the movable plate 4. The movable plate 4 has a slot corresponding to the positioning plate 11, allowing the positioning plate 11 to move left and right. The insert 13 is inserted into the top of the trapezoidal block 9. The trapezoidal block 9 has multiple sets of slots corresponding to the insert 13. The bottom end of the fixing frame 6 is in contact with the upper surface of the triangular block 12. When the fixing frame 6 presses the triangular block 12, it causes the triangular block 12 to move backward. The insert 13 passes through and is slidably connected to the inner wall of the triangular block 12. The triangular block 12 has a slot corresponding to the insert 13, allowing the insert 13 to move vertically. The inner wall of the fixing frame 6 is in contact with the outer wall of the movable plate 4.

[0038] Working principle: When it is necessary to press an item, manually place the item between the two sets of positioning plates 11. Then, the electric sliding rail 3 moves the moving plate 4 to directly below the fixed frame 6. The external electric telescopic rod 5 moves the fixed frame 6 downward. When the fixed frame 6 moves downward and contacts the triangular block 12, the bottom of the fixed frame 6 will press the triangular block 12, causing the triangular block 12 to move backward with the trapezoidal block 9 and press the movable spring 10. The inclined groove on the trapezoidal block 9 will press the two sets of positioning plates 11, causing the two sets of positioning plates 11 to move closer together to position the item. At this time, the fixed frame 6 and the moving plate 4 are pressed together. Plate 4 forms a sealed space. Then, the vacuum pump is turned on to extract the air from the fixed frame 6. Then, the pressure plate 8 is moved downward by the electro-hydraulic rod 7. The pressure plate 8 will press the object. After pressing, the fixed frame 6 is moved to the initial position by the electro-electric telescopic rod 5 and the hydraulic rod 7. When the fixed frame 6 no longer contacts the triangular block 12, it moves to the initial position by the elastic force of the movable spring 10, along with the triangular block 12 and the trapezoidal block 9. The inclined groove on the trapezoidal block 9 will squeeze the two sets of positioning plates 11 to separate from each other and contact the positioning of the item. At this time, the staff can manually remove the item.

[0039] When positioning a larger object, manually move the insert block 13 upwards. The insert block 13 will compress the moving spring 14. When the insert block 13 separates from the slot on the trapezoidal block 9, manually move the triangular block 12 backwards. When the triangular block 12 moves to the desired position, the insert block 13 coincides with the slot on the trapezoidal block 9. Manually release the insert block 13, and use the elastic force of the moving spring 14 to insert the insert block 13 into the slot on the trapezoidal block 9, thus completing the positioning of the triangular block 12. As the position of the triangular block 12 changes, when the fixed frame 6 compresses the triangular block 12 again, the moving distance of the trapezoidal block 9 compressing the positioning plate 11 becomes shorter due to the shorter moving position of the fixed frame 6 compressing the triangular block 12. This increases the space between the two sets of positioning plates 11, allowing the positioning plate 11 to position larger objects.

[0040] When shim 15 needs to be replaced, manually move the locking block 17 to the left. The locking block 17 will compress the positioning spring 19. When the locking block 17 separates from the slot on the slot 16, manually move the locking block 17 and the baffle 18 upwards. When the baffle 18 no longer blocks the shim 15, the locking block 17 will coincide with the second slot on the slot 16. Manually release the locking block 17, and use the elastic force of the positioning spring 19 to engage the locking block 17 into the slot of the slot 16, thus limiting the position of the baffle 18. Then, manually remove the shim 15. A new shim needs to be installed. At 15 o'clock, manually align the gasket 15 and insert it into the slot of the pressing plate 8. Then, manually move the locking block 17 to the left. When the locking block 17 separates from the slot on the slot 16, manually move the locking block 17 and the baffle 18 downward. When the baffle 18 blocks the gasket 15, the locking block 17 coincides with the slot on the slot 16. Manually release the locking block 17 so that it engages with the slot on the slot 16, thus limiting the position of the gasket 15. If it is necessary to install or remove the gasket 15 again, simply repeat the above steps.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
