The vibration press head is installed on the top of the press base, and the vacuum frame is installed on the press base. Among them, a vacuum pipe is provided on the press base, and the vacuum pipe can extract gas from the bottom of the vacuum frame. The vibration press head is also provided with a vacuum pipe, which can extract gas from the top of the vacuum frame. At this time, the two vacuum pipes work together to effectively remove the gas in the vacuum frame, ensure that the vacuum frame is in a vacuum state, and further improve the pressing effect and product quality.

[0003] Therefore, in order to better improve the pressing effect of the vibration press and prevent the vacuum frame from leaking during the vibration process, resulting in a decrease in vacuum degree, a square sealing strip is provided between the vacuum frame and the frame. However, the square sealing piece has a certain elastic deformation, and the staff needs to force the square sealing strip into the gap between the vacuum frame and the frame. At this time, the square sealing strip is prone to elastic deformation, and it is difficult to ensure that the multiple side walls of the square sealing strip are respectively in contact with the side walls of the vacuum frame and the frame, making the installation of the square sealing strip difficult.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "splicing", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Combine the following Figure 1 to Figure 2 , describing a vibrating pressure head sealing strip according to an embodiment of the utility model.

[0027] A vibration pressure head sealing strip comprises a main body 1, one side of the main body 1 is provided with an inclined first inclined portion 2 and a second inclined portion 3 in sequence from top to bottom, and the main body 1, the first inclined portion 2 and the second inclined portion 3 are formed by an integrated molding process;

[0028] A first abutting surface 21 is disposed on a side of the first inclined portion 2 away from the main body 1 , and a second abutting surface 31 is disposed on a side of the second inclined portion 3 away from the main body 1 .

[0029] The vibration pressure head sealing strip of the present solution is installed in the gap between the vacuum frame and the frame, wherein the side wall of the main body 1 away from the first inclined portion 2 is tightly fitted with the vacuum frame, and the first abutting surface 21 and the second abutting surface 31 are respectively abutted with the frame, which can limit the movable position of the vacuum frame and prevent the vacuum frame from being displaced.

[0030] Since the first inclined portion 2 is installed at the top of one side of the main body 1, the staff can adjust the inclination angle of the first inclined portion 2 so that the first abutting surface 21 on the first inclined portion 2 can fit tightly with the frame. The second inclined portion 3 is installed at the bottom of the main body 1 on the side close to the first inclined portion 2. At this time, the staff can adjust the inclination angle of the second inclined portion 3 so that the second abutting surface 31 of the second inclined portion 3 can fit tightly with the frame.

[0031] The first inclined portion 2 and the second inclined portion 3 cooperate with each other, not only can the vibration pressure head sealing strip of the present solution be installed between the vacuum frame and the frame, solving the problem that the traditional square sealing strip is difficult to install, but also can make the vibration pressure head sealing strip of the present solution tightly connect the vacuum frame and the frame, preventing the vacuum frame from being offset.

[0032] In addition, the first inclined portion 2 and the main body 1 form a Y-shaped structure. When the vacuum pipe on the vibrating pressure head is started, the Y-shaped structure can achieve a better sealing effect, preventing the vacuum pipe on the vibrating pressure head from sucking air from the outer wall of the vacuum frame, thereby further improving the sealing effect of the vacuum frame.

[0033] The second inclined portion 3 and the main body 1 also form a Y-shaped structure. When the vacuum pipe on the vibration base is started, the second inclined portion 3 tilts outward and presses against the frame, so that the Y-shaped structure can have a better sealing effect and prevent the top and bottom of the vacuum frame from being connected.

[0034] The inclination angle a between the first inclined portion 2 and the main body 1 is 25°-35°;

[0035] An inclination angle b between the second inclined portion 3 and the main body 1 is 25°-35°.

[0036] When there is a slight unevenness or gap between the vibration pressure head sealing strip of the present solution and the frame, the outwardly inclined first inclined portion 2 and the second inclined portion 3 can better fill these unevenness or gaps, thereby improving the sealing effect of the vibration pressure head sealing strip of the present solution. The present solution limits the inclination angles of the first inclined portion 2 and the second inclined portion 3, which can further improve the sealing performance of the vibration pressure head sealing strip of the present solution, so that the vibration pressure head sealing strip of the present solution can maintain good sealing performance in various use environments.

[0037] The main body 1 is provided with a plurality of process holes 4 , and the process holes 4 horizontally penetrate the left and right sides of the main body 1 .

[0038] The process hole 4 can effectively remove the gas and cutting slag generated during the processing of the vibration pressure head sealing strip of this solution, prevent the gas and cutting slag from damaging the vibration pressure head sealing strip, and improve the processing quality and efficiency of the vibration pressure head sealing strip.

[0039] Moreover, the process hole 4 can reduce the weight of the vibration pressure head sealing strip and save material costs while ensuring the strength and rigidity of the vibration pressure head sealing strip.

[0040] A groove 5 with an opening direction facing outward horizontally is provided on one side of the main body 1 away from the first inclined portion 2 . The groove 5 runs horizontally through the left and right sides of the main body 1 , and the sidewall of the groove 5 is inclined from outside to inside.

[0041] Reference Figure 2 When the staff needs to disassemble the vibration pressure head sealing strip of the present solution, they can extend the long rod into the groove 5, and then move the long rod up and down to separate the main body 1 from the vacuum frame, so that the vibration pressure head sealing strip of the present solution can be quickly disassembled.

[0042] The side wall of the groove 5 is inclined from outside to inside, which can guide the long rod to extend into the gap between the main body 1 and the vacuum frame, further improving the disassembly speed of the vibration pressure head sealing strip of the present solution.

[0043] The thickness Y of the upper end of the main body 1 is 9-11 mm, and the thickness D of the lower end of the main body 1 is 20-24 mm.

[0044] It is worth noting that the upper end of the main body 1 is narrower, with a thickness of only 9-11 mm, which can reduce the resistance of the vibration pressure head sealing strip of the present solution when inserted into the gap between the vacuum frame and the frame, making it easier to insert. The lower end of the main body 1 is wider, with a thickness of between 20-24 mm, which can provide a better sealing effect.

[0045] The main body 1 , the first inclined portion 2 , and the second inclined portion 3 are all made of silicone rubber.

[0046] It is worth noting that silicone rubber materials have high high-temperature stability. Even in a high-temperature environment above 200°C, silicone rubber materials can still maintain a certain flexibility, resilience and surface hardness, and there is no obvious change in mechanical properties.

[0047] The Shore hardness of the main body 1 , the first inclined portion 2 and the second inclined portion 3 is 40-50.

[0048] The present solution defines the Shore hardness of the main body 1, the first inclined portion 2, and the second inclined portion 3, so that the vibration pressure head sealing strip of the present solution can produce appropriate deformation when subjected to pressure, effectively fill the sealing gap, and ensure the sealing performance of the vibration pressure head sealing strip of the present solution. In addition, the vibration pressure head sealing strip with a Shore hardness of 40-50 has good wear resistance and durability, and can withstand certain friction and extrusion during the sealing process without being easily damaged, thereby extending the service life.

[0049] The first abutting surface 21 is in a vertical direction, and the second abutting surface 31 is in a vertical direction.

[0050] The vertical first abutting surface 21 can increase the contact area between the first abutting surface 21 and the frame, so that the first abutting surface 21 and the frame are closely fitted. The vertical second abutting surface 31 can increase the contact area between the second abutting surface 31 and the frame, so that the second abutting surface 31 and the frame are closely fitted.

[0051] 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.
