DETAILED DESCRIPTION

[0024] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0025] Embodiment: A demoulding device for 3D printed parts processing, such as Figure 1-Figure 5 As shown, it includes a body 1, a Y-axis telescopic frame 11 and a placement plate 12. The Y-axis telescopic frame 11 is arranged on the body 1, and the Z-axis telescopic frame is arranged at the rear end of the body 1. The print head is connected to the Z-axis telescopic frame through an X-axis rod. The placement plate 12 is fixed on the Y-axis telescopic frame 11. The bottom of the front end of the placement plate 12 is suspended and does not contact the Y-axis telescopic frame 11. The placement plate 12 has good toughness and a smooth upper surface. It also includes a fixing frame 2, a flip frame 21, a cutting plate 22, a locking frame 23, an elastic member a24 and a pressing component The fixed frame 2 is fixedly connected to the front end of the machine body 1, the flip frame 21 is rotatably connected to the front end of the fixed frame 2, the front end of the cutting plate 22 is rotatably connected to the flip frame 21, the locking frame 23 is slidably connected to the front end of the flip frame 21, the top of the locking frame 23 passes through the left and right ends of the cutting plate 22, the rear end of the cutting plate 22 is a thin sheet with high hardness, and an elastic member a24 is sleeved on the locking frame 23, one end of the elastic member a24 is fixedly connected to the locking frame 23, and the other end is fixedly connected to the flip frame 21, and a pressing component for pressing down the placement plate 12 is provided on the fixed frame 2.

[0026] like Figure 5 and Figure 6As shown, the pressing assembly includes an extension rod 3, an elastic member b31 and a pressing frame 32. The extension rod 3 is fixedly connected to the round rods at both ends of the fixed frame 2. The pressing frame 32 is slidably connected to the extension rod 3. An elastic member b31 is sleeved on the extension rod 3. One end of the elastic member b31 is fixedly connected to the fixed frame 2, and the other end is fixedly connected to the pressing frame 32. A handle is provided on the top of the pressing frame 32 to facilitate the control of the movement of the pressing frame 32. The bottom is set to be a semicircle, and the contact process with the placement plate 12 is smoother.

[0027] During the printing process, the printer controls the movement of the X, Y, and Z axes respectively, so that the print head moves according to the calculated path, thereby completing the preset model file. After printing is completed, the placement plate 12 is driven forward by the Y-axis telescopic frame 11. During the forward movement, the upper surface of the front end of the placement plate 12 contacts the rear end of the cutting plate 22. Then, when the placement plate 12 moves below the lower pressing frame 32, the staff presses the lower pressing frame 32 downward, so that the front end of the placement plate 12 is slightly bent downward. Since the placement plate 12 has good toughness, when the cutting plate 22 contacts the bottom of the printed object, it can be smoothly inserted into the bottom of the object and separated from the placement plate 12. Then, the lower pressing frame 32 is released, and the elastic member b31 rebounds and no longer squeezes the placement plate 12. With the movement of the Y-axis telescopic frame 11, The contact area between the placement plate 12 and the cutting plate 22 becomes larger and larger, and the printed object is slowly transferred to the cutting plate 22 and detached from the placement plate 12, completing the demoulding of the printed object. After removing the redundant support connection at the bottom of the printed object on the cutting plate 22, the target object is obtained, and the locking frame 23 is pulled down to compress the elastic member a24, contact the restriction of the cutting plate 22, lift the cutting plate 22 forward, and the redundant support connection slides off the cutting plate 22, and the cutting plate 22 is cleared. Since the plastic of the supporting connection and the black surface of the target object are relatively smooth, it is easy to scratch the staff when cleaning by hand, so the inclined cutting plate 22 can protect the staff, and then the cutting plate 22 is reset, and the locking frame 23 is released. The locking frame 23 is inserted into the left and right sides of the cutting plate 22 under the rebound force of the elastic member a24, thereby fixing the cutting plate 22.

[0028] like Figure 6 and Figure 7 As shown, it also includes a limit block 4, a limit rod 41, a guide piece 42 and an elastic member c43. The limit block 4 is fixedly connected to the rear end of the flip frame 21, and guide pieces 42 are fixedly connected to both sides of the front end of the fixed frame 2. The limit rod 41 is slidably connected to the guide piece 42. The two limit rods 41 are connected by a connecting frame. A pull ring is provided at one end of the limit rod 41 connecting frame to facilitate pulling out the two limit rods 41 at the same time. An elastic member c43 is sleeved on the limit rod 41, and one end of the elastic member c43 is fixedly connected to the limit rod 41, and the other end is fixedly connected to the guide piece 42.

[0029] When the 3D printer is not in use, the flip frame 21 is rotated backward. When it is rotated 90 degrees, the limit block 4 contacts the limit rod 41, and the limit block 4 squeezes the limit rod 41 to move and compresses the elastic member c43. When the limit rod 41 is aligned with the middle square hole of the limit block 4, the elastic member c43 rebounds, so that the limit rod 41 is inserted into the limit block 4, thereby fixing the flip frame 21. When it is needed, pull the connecting frame connected to the limit rod 41 to disengage the limit rod 41 from the limit block 4, and then rotate the flip frame 21 to make it rotate forward 90 degrees and fully unfold.

[0030] like Figure 7 As shown, it also includes a squeezing plate 5 and a pulling plate 51. The squeezing plate 5 is fixedly connected to the front end of the Y-axis telescopic frame 11, and the pulling plate 51 is fixedly connected to the left and right sides of the lower pressing frame 32. The squeezing plate 5 is slidably connected to the pulling plate 51.

[0031] like Figure 8 As shown, it also includes a fixed plate 6, a support frame 61 and an elastic member d62. The fixed plate 6 is fixedly connected to the left and right sides of the upper front end of the body 1. The support plate is slidably connected to the fixed plate 6, and the top of the support frame 61 is in contact with the bottom of the placement plate 12. An elastic member d62 is arranged on the support frame 61. One end of the elastic member d62 is fixedly connected to the support frame 61, and the other end is fixedly connected to the fixed plate 6.

[0032] like Figure 8 As shown, it also includes a round head block 7. The front and rear sides of the support frame 61 are inclined surfaces. The round head blocks 7 are fixedly connected to the front and rear ends of the left and right sides of the Y-axis telescopic frame 11, and the round head blocks 7 are in contact with the side of the support frame 61.

[0033] During the printing process, the support frame 61 supports the left and right sides of the front end of the placement plate 12, so that the placement plate 12 is more flat during printing. After printing, when the placement plate 12 moves forward, the round head block 7 at the front end squeezes the support frame 61, pushes the support frame 61 to both sides, and compresses the elastic member d62. At the same time, the squeezing plate 5 at the front end of the Y-axis telescopic frame 11 contacts the pulling plate 51, presses the pulling plate 51 downward, drives the lower pressing frame 32 to move downward, squeezes the placement plate 12, and at this time, the support frame 61 has been in contact with the front of the placement plate 12. The end is detached, so as not to affect the bending of the placement plate 12. Moreover, when the Y-axis telescopic frame 11 is reset, since the lower pressure frame 32 is not under force, there is still a distance from the top of the extension rod 3. Therefore, when the extrusion plate 5 reversely squeezes and pulls the plate 51, it will push the lower pressure frame 32 to move upward and stretch the elastic member b31, but it will not contact the top of the extension rod 3, so that the extrusion plate 5 can pass smoothly, and then the elastic member b31 is reset. At the same time, a round head block 7 is also provided at the rear end of the Y-axis telescopic frame 11, which can squeeze the support frame 61 to move to both sides.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
