Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a product molding cooling device for 3D printing. Background Art

[0002] 3D printing is a technology that uses digital model files as the basis, using powdered metal, plastic and other bondable materials to construct objects by printing layer by layer. The technology was first proposed by the United States in the mid-1980s. 3D printing is often used to manufacture models in the fields of mold manufacturing, industrial design, etc., and later gradually used for the direct manufacturing of some products. It has a profound impact on traditional process flows, production lines, factory models, and industrial chain combinations. It is a representative disruptive technology in the manufacturing industry.

[0003] After searching, the Chinese patent publication number is CN218701328U, which discloses a 3D printing product molding cooling device. The motor drives the carrier plate to rotate slowly, so that the 3D printed product placed on the carrier plate can also rotate accordingly. At the same time, the air pump blows air into the two square tubes through the three-way pipe, so that the blown air flow can be ejected through the nozzles set on the outer surface of the square tube, so that the ejected air flow can cool the 3D printed product. By cooling the 3D printed product during the rotation process, it is ensured that the entire 3D printed product can obtain a cooling effect, thereby improving the overall cooling speed of the 3D printed product.

[0004] Generally, the structure of 3D printed products is relatively complex and has some irregular surfaces. However, during use of the above-mentioned patent, the nozzle cannot adjust the jet angle, so it cannot spray into some gaps in the product, which is not conducive to the overall cooling of the product.
