[0002] With the development of technology, 3D printing is used more and more. Usually, when a 3D printing device is printing, it prints an object layer by layer. Based on the principle that photosensitive resin solidifies when exposed to ultraviolet light, the computer controls the light source to irradiate the selected part of the liquid photosensitive resin according to the drawing of the layered cross-section of the object to be printed, thereby solidifying, that is, printing the photosensitive resin of that part. After curing and printing layer by layer, a solid object to be printed can be finally obtained.

[0003] A 3D printing device usually includes a material trough, a curing light source that emits light toward the material trough, a forming table arranged above the material trough, and a lifting mechanism that drives the forming table to rise and fall. The forming table is usually detachably connected to the lifting mechanism through a threaded structure, but this requires special disassembly tools, is cumbersome to operate, and has a poor user experience.

[0028] See also Figure 1 An embodiment of the utility model provides a forming table mechanism, including: a mounting seat 10 and a forming table 20.

[0029] Please also see Figure 1 and Figure 2 A rotating member 11 and a supporting portion 12 are provided on the mounting seat 10, and the rotating member 11 is rotatably matched with the mounting seat 10, and a pressing portion 13 is provided on the rotating member 11; a mounting plate 21 is provided on the forming table 20, and the mounting plate 21 extends between the rotating member 11 and the supporting portion 12. After the rotating member 11 rotates, the pressing portion 13 is driven to press the mounting plate 21 toward the supporting portion 12, so that the forming table 20 and the mounting seat 10 can be detachably matched. When the forming table 20 needs to be removed, the user moves the rotating member 11 to make the pressing portion 13 away from the mounting plate 21, thereby making the pressing portion 13 loosen the mounting plate 21, and then the mounting plate 21 can be removed from the supporting portion 12. The overall structure is simple and easy to operate.

[0030] In some optional embodiments, supporting parts 12 are respectively provided on both sides of the mounting seat 10, clamping parts 13 are respectively provided on both sides of the rotating member 11, and two mounting plates 21 are provided on the forming table 20. The mounting plates 21 extend between the clamping parts 13 and the supporting parts 12 respectively, and the forming table 20 is locked at the two side positions of the mounting seat 10 through the clamping parts 13, so that the installation stability of the forming table 20 is improved, the overall structure is more stable, and the forming table 20 is not easy to shake left and right when in use.

[0031] In some optional embodiments, the rotating member 11 is a U-shaped rotating handle, and a clamping portion 13 is respectively provided at both ends of the U-shaped rotating handle. The design of the U-shaped rotating handle makes it easy for the user to bend the U-shaped rotating handle, making the operation more convenient.

[0032] The formation method of the support portion 12 can be designed according to actual needs. For example, in some optional embodiments, a support step 14 is formed on the side of the mounting seat 10, and the top of the support step 14 is formed with the support portion 12. The clamping portion 13 is arranged above the support portion 12. After the mounting plate 21 extends into the support portion 12, the clamping portion 13 presses the mounting plate 21 onto the support step 14.

[0033] In some optional embodiments, a support step 14 is formed on the side of the mounting seat 10, a support portion 12 is formed on the top of the support step 14, a clamping portion 13 is arranged above the support portion 12, and a limit block is provided on the mounting plate 21. When installing the forming table 20, the mounting plate 21 slides along the support step 14 and then extends between the clamping portion 13 and the support portion 12. At this time, the limit block abuts against the mounting seat 10, which is convenient for the user to judge whether the mounting plate 21 has moved to the correct position. After the clamping portion 13 presses the mounting plate 21 on the support portion 12, the limit block can also assist in limiting the position of the mounting plate 21, thereby improving the position stability of the mounting plate 21, and thereby improving the structural stability of the forming table 20. In this embodiment, the support portion 12 is below the mounting plate 21, the clamping portion 13 is above the mounting plate 21, and the mounting seat 10 and the limit block are on different sides of the mounting plate 21, so that the mounting plate 21 is restricted in different directions, so that the position of the mounting plate 21 is not easy to shake.

[0034] In some optional embodiments, a gripping handle 24 is provided on the mounting plate 21 to facilitate the user to take the forming table 20 while preventing the user from touching the bottom of the forming table 20 .

[0035] The specific structure of the mounting plate 21 can be designed according to actual needs. For example, in some optional embodiments, the mounting plate 21 includes a horizontal plate 22 and a vertical plate 23 that are connected to each other. The horizontal plate 22 extends between the rotating member 11 and the supporting portion 12. After the rotating member 11 rotates, the pressing portion 13 is driven to press the horizontal plate 22 toward the supporting portion 12. The vertical plate 23 is connected to the forming table 20. The gripping handle 24 is arranged on the side of the vertical plate 23 away from the mounting seat 10 to prevent the mounting seat 10 from interfering with the user's gripping of the gripping handle 24, thereby facilitating the user's gripping.

[0036] In some optional embodiments, a positioning groove 25 is provided on the mounting plate 21. After the rotating member 11 rotates, the pressing portion 13 is driven to extend into the positioning groove 25. The pressing portion 13 presses against the inner wall of the positioning groove 25 to press the mounting plate 21 toward the support portion 12. When the mounting plate 21 slides relative to the support portion 12 due to insufficient pressing force or other unexpected factors, the mounting plate 21 may be detached from between the support portion 12 and the pressing portion 13. The design of the positioning groove 25 can position the pressing portion 13 in the positioning groove 25, so that the mounting plate 21 cannot slide along the support portion 12 when being pressed by the pressing portion 13, thereby improving the stability of the structure. In this embodiment, the positioning groove 25 is provided on the horizontal plate 22.

[0037] See also Figure 3In some optional embodiments, the side wall of the positioning groove 25 is formed with an avoidance slope 26 for avoiding the rotation of the clamping portion 13. After the mounting plate 21 penetrates into between the clamping portion 13 and the supporting portion 12, when the clamping portion 13 rotates toward the inner wall of the positioning groove 25, the opening edge of the positioning groove 25 and the inner wall of the positioning groove 25 may hinder the clamping portion 13 from rotating into the positioning groove 25. The design of the avoidance slope 26 can adapt to the rotation path of the clamping portion 13, thereby avoiding the situation where the clamping portion 13 is stuck outside the positioning groove 25.

[0038] The above-mentioned molding table mechanism can be applied to a 3D printing device, which includes: the above-mentioned molding table mechanism. The 3D printing device generally also includes a material slot, a curing light source emitting light toward the material slot, a molding table mechanism disposed above the material slot, and a lifting mechanism driving the molding table mechanism to rise and fall, the lifting mechanism being drivingly connected to the mounting seat 10 of the molding table mechanism, thereby driving the entire molding table mechanism to rise and fall relative to the material slot.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
