Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and more specifically, to a UV oven for curing 3D printed parts. Background Art

[0002] 3D printing technology is a rapid manufacturing technology that constructs objects by adding materials layer by layer. This technology has been widely used in many fields. Curing is an important step in the 3D printing process. It usually involves the process of converting the printing material from a printable state to a final solid state. Using a UV oven for light curing is a common curing method. The main working principle of a UV oven is to stimulate the photoinitiator or photosensitizer in the material through ultraviolet radiation, thereby initiating chemical reactions such as polymerization and cross-linking, so that the material is converted from liquid to solid within seconds to minutes. This process greatly improves production efficiency and reduces the time and energy required for traditional thermal curing.

[0003] In existing UV ovens, light utilization is not high. Although UV light sources are installed on all sides of the box, if partitions are installed in the box, the parts to be cured will be blocked by the partitions when placed on the partitions, reducing light utilization and thus reducing the quality of the parts. At the same time, when the printed parts are moved by moving the partitions, the friction loss between the moving rails and the partitions aggravates the wear of the partitions, affecting the service life of the oven body. When the oven is working, it is not convenient to ventilate the exhaust gas generated by the printed parts. Utility Model Content

[0015] (3) Beneficial effects

[0016] Compared with the existing technology, the present invention provides a UV oven for curing 3D printed parts, which has the following beneficial effects:

[0017] 1. By setting up multiple UV lamps around the inside of the oven body, it is convenient to carry out all-round irradiation and curing of the printed parts. The position of the transparent partition and the printed parts can be moved by cooperating with the sliding track and the sliding block. By setting the transparent partition as a support, the light transmittance of the partition is increased, and the curing effect is improved.

[0018] 2. A lubrication cavity is provided on the sliding track to facilitate storage of lubricating oil. The lubrication head on the lubrication rod is moved into the lubrication groove, causing the lubrication rod to move downward. After the circulation groove and the oil outlet groove are aligned, the lubricating oil flows out through the circulation groove and the oil outlet groove to lubricate the sliding block and the sliding track, thereby improving the smoothness of the movement of the transparent partition and reducing friction loss. When the sliding block and the transparent partition are completely inserted into the oven body, the sliding block supports the lubrication rod and the lubrication head to move upward, causing the circulation groove and the oil outlet groove to be staggered, thereby preventing waste of lubricating oil.

[0019] 3. By setting up a ventilation fan, it is convenient to ventilate the interior of the oven body. Through the activated carbon layer and the filter net, it is convenient to filter and adsorb the ventilated dust, impurities and exhaust gas, thereby improving the practicality of the filtering device.

[0031] In this embodiment, when in use, the transparent partition 5 is pulled outward, and the transparent partition 5 drives the sliding block 4 to move in the sliding track 3. When the sliding block 4 moves, when the lubrication head 8 is aligned with the lubrication groove 11, the movable plate 13 drives the lubrication rod 7 and the movable groove 12 to move downward under the elastic force of the movable spring 14, so that the lubrication head 8 extends into the movable groove 12. At the same time, the flow groove 9 and the oil outlet groove 10 on the lubrication rod 7 are aligned, and the lubricating oil in the lubrication cavity 6 flows out between the sliding block 4 and the sliding track 3 through the flow groove 9 and the oil outlet groove 10, thereby irritating the sliding track 3 and the sliding block. 4 is lubricated, and the printed part to be cured is placed on the transparent partition 5.

By providing an installation drawer 19, it is convenient to replace the activated carbon plate 18. By moving the toggle rod 24, the mounting rod 21 is driven to move in opposite directions and squeeze the mounting spring 25, so that the mounting rod 21 leaves the mounting hole 22, which is convenient for replacing and cleaning the filter screen 17. When installing the mounting bracket 20 and the filter screen 17, after squeezing the toggle rod 24 and the mounting spring 25, the mounting bracket 20 is positioned and installed by the cooperation of the positioning block 26 and the positioning groove 27, and then the toggle rod 24 is released.

[0034] In summary, when the entire device is in use or running: when in use, the transparent partition 5 is pulled outward, and the transparent partition 5 drives the sliding block 4 to move in the sliding track 3. When the sliding block 4 moves, when the lubrication head 8 is aligned with the lubrication groove 11, the movable plate 13 drives the lubrication rod 7 and the movable groove 12 to move downward under the elastic force of the movable spring 14, so that the lubrication head 8 extends into the movable groove 12, and at the same time, the circulation groove 9 and the oil outlet groove 10 on the lubrication rod 7 are aligned, and the lubricating oil in the lubrication cavity 6 flows out between the sliding block 4 and the sliding track 3 through the circulation groove 9 and the oil outlet groove 10, thereby urging the sliding track 3 to move downward. Lubrication is carried out between the sliding block 4, and the printed part to be cured is placed on the transparent partition 5. When the transparent partition 5 drives the printed part to extend back into the oven body 1, one end of the movable groove 12 squeezes the lubrication rod 7 upward, so that the movable plate 13 squeezes the movable spring 14 upward, and the lubrication rod 7 moves upward, so that the flow groove 9 and the oil outlet groove 10 are staggered, thereby preventing the lubricating oil from continuing to flow out and preventing the waste of lubricating oil.
