[0024] The present invention proposes a quick-detachable printing base plate based on polymer material 3D printing. After the model is formed on the surface of the upper plate 4, the handle 55 is pulled to drive the control block 5 to move, so that the guide groove 52 and the guide column 62 move relative to each other. Under the guiding action of the guide groove 52, the guide column 62 drives the positioning block 6 to retract into the interior of the slide groove 33, so that the positioning block 6 is disengaged from the interior of the positioning groove 23.

Under the rebound action of the first compression spring 39, the upper plate 4 rises, and the positioning slide 47 enters the inside of the high-level groove 371 along the third guide platform 377, so that the height of the upper plate 4 is higher than the fixed column 38, driving the model to be peeled off from the fixed column 38, thereby completing the peeling of the model. The operation is simple and fast, and the scraper damages the model.

[0026] As a further improvement of the present invention, after the model is peeled off, the upper plate 4 is pressed to make the positioning slide 47 enter the interior of the upper transition groove 373 along the first guide platform 374, and then enter the interior of the low-level groove 372 along the second guide platform 375 under the rebound action of the first compression spring 39, so that the upper plate 4 is flush with the fixed column 38, and then the T-shaped block 31 is inserted into the interior of the T-shaped groove 22, so that the positioning block 6 is stuck in the interior of the positioning groove 23, and printing can continue.

[0027] Working principle: The present invention proposes a quick-detachable printing base plate based on polymer material 3D printing. After the model is formed on the surface of the upper plate 4, the handle 55 is pulled to drive the control block 5 to move, so that the guide groove 52 and the guide column 62 move relative to each other. Under the guiding action of the guide groove 52, the guide column 62 drives the positioning block 6 to retract into the interior of the slide groove 33, so that the positioning block 6 is disengaged from the interior of the positioning groove 23. At this time, continue to pull the handle 55 to drive the T-shaped block 31 to disengage from the interior of the T-shaped groove 22, and then press down the two ends of the upper plate 4 to make the upper plate 4 descend. The positioning slide column 47 disengages from the interior of the low-level groove 372 and enters the interior of the lower transition groove 376. At this time, under the support of the fixed column 38, the upper plate 4 is peeled off from the model. Then release the pressure on the positioning slide 47, and under the rebound action of the first compression spring 39, the upper plate 4 rises, and the positioning slide 47 enters the inside of the high-level groove 371 along the third guide platform 377, so that the height of the upper plate 4 is higher than the fixed column 38, driving the model to be peeled off from the fixed column 38, thereby completing the peeling of the model, and then press the upper plate 4 again, so that the positioning slide 47 enters the inside of the upper transition groove 373 along the first guide platform 374, and then, under the rebound action of the first compression spring 39, enters the inside of the low-level groove 372 along the second guide platform 375, so that the upper plate 4 is flush with the fixed column 38, and then insert the T-shaped block 31 into the inside of the T-shaped slot 22, so that the positioning block 6 is stuck in the inside of the positioning slot 23, and then printing can continue.
