[0033] like Figure 2 As shown, the position adjustment device 1 in the embodiment of the utility model includes a slide table 8, a slide rail 9, a slider 10 and a translation drive structure. Two slide rails 9 arranged at intervals are fixed on the upper end surface of the slide table 8. The lower end of the slider 10 is slidably connected to the two slide rails 9. The side surface of the support plate 3 of the clamping device 2 is fixedly connected to the outer side of the slider 9 through a connecting rod 11, and the translation drive structure is connected to the slider 9.

[0034] Preferably, the translational drive structure in the embodiment of the utility model includes a drive motor 12 and a lead screw 13, wherein the drive motor 12 is fixed at one end of the upper side of the slide 8, one end of the lead screw 13 is fixedly connected to the output shaft of the drive motor 12, and the other end of the lead screw 13 is connected to the upper side of the slide 8 through a bearing seat 14, and a threaded hole matching the lead screw 13 is opened in the middle of the slider 9.

[0035] like Figure 3 As shown, the clamping device 2 in the embodiment of the utility model includes a support plate 3 and two clamping plates 4, the middle of the support plate 3 is provided with two transverse slots 5 spaced apart up and down, one end of the two clamping plates 4 are fixed with two fixing blocks 6, the two fixing blocks 6 are respectively slidably installed in the two transverse slots 5, and the outer side of the clamping plate 4 is connected to a clamping drive structure.

[0036] Preferably, the clamping drive structure in the embodiment of the utility model includes an electric push rod 15, and an electric push rod 15 is fixed to each of the two ends of the outer side of the support plate 3, and the output ends of the two electric push rods 15 are respectively fixedly connected to the outer sides of the two clamping plates 4. The two clamping plates 4 can be driven separately by the two electric push rods 15 to achieve the opening and closing adjustment of the two clamping plates 4.

[0037] Preferably, a pressure detection sensor 16 is respectively embedded on the opposite side of the two clamping plates 4 of the clamping device 2 in the embodiment of the utility model, and the pressure detection sensor 16 is connected to the external controller through a connecting line. The clamping force of the two clamping plates 4 can be detected by the pressure detection sensor 16, which is convenient for setting the parameters of the clamping force.

[0038] like Figure 3 As shown, the positioning device in the embodiment of the utility model includes a distance detection sensor 7, and the distance detection sensor 7 is fixed in the middle of the outer side of the support plate 3. The distance detection sensor 7 can detect the distance between the clamping device 2 and the mold, so as to locate the position of the clamping device 2.

[0039] Preferably, a groove is provided in the middle of the outer side of the support plate 3 in the embodiment of the utility model, the distance detection sensor 7 is installed in the groove, and a transparent protective plate is embedded in the outer end of the groove. The distance detection sensor 7 can be effectively protected by the groove and the transparent protective plate.

[0040] The working principle of the utility model is as follows: when the utility model is used, the loading and unloading mechanism is installed on the outside of the shaping mold of the 3D automatic shaping machine, and the user sets the relevant parameters of the loading and unloading mechanism through the external controller, including the clamping force, the translation distance, etc. The setting of these parameters ensures that the loading and unloading mechanism can adapt to molds of different sizes and weights.

[0041] After the loading and unloading mechanism is started, the position adjustment device 1 starts to work. The driving motor 12 in the translation drive structure is started to drive the lead screw 13 to rotate. Since a threaded hole that cooperates with the lead screw 13 is opened in the middle of the slider 10, the rotation of the lead screw 13 causes the slider 10 to slide along the slide rail 9. This translation movement causes the clamping device 2 to drive the positioning device to approach the mold. In the process of approaching the mold, the distance detection sensor 7 continuously detects the distance between the clamping device 2 and the mold. When the preset approach distance is reached, the translation drive structure stops working to ensure that the clamping device 2 can accurately align with the mold. The clamping drive structure starts to work. The output end of the electric push rod 15 pushes the clamping plate 4 to move toward the mold until the two clamping plates 4 clamp the mold. During the clamping process, the pressure detection sensor 16 will detect the clamping force in real time to ensure that the mold is firmly clamped and avoid damage to the mold caused by excessive clamping. When the mold is firmly clamped, the driving motor 12 rotates in the opposite direction, and the slider 10 drives the clamping device 2 and the mold to move in the opposite direction to achieve the disassembly of the mold.
