Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and more specifically, to a photosensitive resin tank for continuous light-curing 3D printing. Background Art

[0002] 3D printing has developed rapidly around the world. 3D printing research and development has sprung up like mushrooms after rain and has flourished. High-precision 3D printer technology has made great strides. DLP light-curing 3D printing technology has become more and more mature, and higher requirements have been placed on the resin tank used for printing. The resin tank with good release effect, not easy to deform, and long service life is an indispensable key component of DLP light-curing 3D printers. Light-curing 3D printers are based on the principle of light-curing molding. Unlike FDM machines that use filaments, light-curing 3D printer consumables are photosensitive resins with high molding accuracy and good surface effects. The surface of the model is smoother than that of PLA material.

[0003] Among them, the patent application number CN201820734534.0 discloses a photosensitive resin tank for continuous light-curing 3D printing, the bottom of the photosensitive resin tank is a light-transmitting anti-polymerization layer, the light-transmitting anti-polymerization layer corresponds to the projection area of ​​the light source, the light-transmitting anti-polymerization layer has high light transmittance and its upper surface contains an inhibitor that can prevent the polymerization of the photosensitive resin. When the photosensitive resin in the photosensitive resin tank is light-cured, a thin liquid curing inhibition layer is formed on the upper surface of the light-transmitting anti-polymerization layer to prevent the cured photosensitive resin from adhering to the bottom surface of the photosensitive resin tank, so that the curing process remains continuous;

[0004] When this structure is in use, it avoids interrupting light irradiation during the photocuring 3D printing process, thereby maintaining the continuity of the curing process. Since the cured photosensitive resin does not need to be repeatedly peeled off from the bottom surface of the photosensitive resin tank, the various molded molds of this structure are easily adhered together during demolding, resulting in inconvenient demolding. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a photosensitive resin tank for continuous light-curing 3D printing, aiming to solve the problems raised in the above-mentioned background technology.

[0006] The utility model provides the following technical solution: a photosensitive resin tank for continuous light-curing 3D printing, comprising a reinforced protective frame for support, wherein a guide assembly is arranged on the reinforced protective frame;

[0007] The guide assembly includes a resin slot mold body arranged in a reinforced protective frame for support, a first mold cavity is arranged on the surface of the resin slot mold body, and a second mold cavity is arranged on one side of the surface of the first mold cavity;

[0008] A plurality of light-transmitting anti-agglomeration strips are disposed on the first mold cavity and the second mold cavity, and the light-transmitting anti-agglomeration strips are arranged in a staggered manner. A central triangular block is disposed on one side of the surface of the first mold cavity, and diversion and guiding strips are disposed on both sides of the surface of the central triangular block. A guide chamber is formed between the plurality of diversion and guiding strips and on the upper surface of the resin tank mold body.

[0009] It can be seen that in the above technical solution, the strengthening protection frame provides a good support point for the resin slot mold body, so that the resin slot mold body is not easily affected by external factors and deformed, thereby ensuring its printing accuracy and making its service life longer. Through the arrangement of the diversion and dredging strips and the central triangular block, it is convenient for the airflow to pass through the diversion chamber formed by each of the two adjacent diversion and dredging strips for diversion, so as to realize the function of combing the airflow, avoid the airflow gathering at a certain place and cause the model to deform during demolding, and improve the demolding quality and demolding efficiency;

[0010] Optionally, in a possible implementation, a reinforcing rib is provided between the resin slot mold body and the reinforcing protection frame, the reinforcing rib is fixedly connected to the reinforcing protection frame and the resin slot mold body, a plurality of flow diversion holes for diversion are provided through both sides of the inner wall of the reinforcing protection frame, and the flow diversion holes are arranged opposite to each other, the flow diversion holes are located at the top of the resin slot mold body, and a cutting strip is provided between the reinforcing rib and the reinforcing protection frame;

[0011] It can be seen that in the above technical solution, the external airflow is transported to the guide hole through the air pump and the conduit, and the material printed on the resin slot mold body can be dropped when the airflow is ejected, so as to prevent the mold body from adhering to the resin slot mold body. A cutting strip is arranged between the reinforcing ribs and the reinforcing protective frame. When the device is in use, when the model is printed on the resin slot mold body, the model can be trimmed and cut according to the position of the cutting strip after demoulding is completed, so as to improve the convenience of subsequent model output;

[0012] Technical effects and advantages of the utility model:

[0013] By setting the guide assembly, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the protective frame is strengthened to provide a good support point for the resin slot mold body, so that the resin slot mold body is not easily affected by external factors and deformed, thereby ensuring its printing accuracy and extending its service life;

[0014] The airflow is delivered to the guide hole through the air pump and the conduit. When the airflow is ejected, the material printed on the resin slot mold body can fall off, preventing the mold body from adhering to the resin slot mold body.

[0015] When the airflow is transported, it passes through the diversion and guiding strips and the central triangle block, which facilitates the airflow to pass through the guide chamber formed by two adjacent diversion and guiding strips to guide the airflow, thereby realizing the function of combing the airflow, avoiding the airflow gathering at a certain point to cause deformation of the model during demoulding, thereby improving the demoulding quality and efficiency. At the same time, after the demoulding is completed, the model can be trimmed and cut according to the position of the cutting strip, thereby improving the convenience of subsequent model production.
