Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, in particular to a 3D printing fixing component for a craft painting mold. Background Art

[0002] In the field of modern manufacturing technology, especially in the production of craft painting molds, 3D printing technology has become an important manufacturing method due to its high efficiency, precision and flexibility. However, despite the many advantages of 3D printing technology, the existing 3D printing fixed components still face some key problems in practical application, which limit the further development and application of 3D printing technology.

[0003] Among them, heat dissipation is one of the main challenges currently faced by 3D printing fixed components. The specific manifestations are as follows:

[0004] Heat accumulation: During the 3D printing process, the printer's nozzle and heated bed generate a lot of heat. Since the existing fixed component design lacks an effective heat dissipation mechanism, this heat easily accumulates in the printing area, causing local overheating.

[0005] Deformation of printing materials: In high temperature environments, printing materials (especially plastic materials) are prone to thermal deformation, resulting in reduced dimensional accuracy of printed parts, and may even cause warping and breakage of the materials.

[0006] Decreased stability of the printing environment: Heat buildup not only affects the printing material, but also the overall performance of the printing device. For example, excessive temperatures may cause electronic components to overheat, thus affecting the stability and service life of the device.

[0007] Print quality issues: Since heat cannot be discharged in time, the uneven temperature during the printing process may lead to poor adhesion between the printed layers, ultimately affecting the surface quality and structural strength of the printed part.

[0008] To this end, we propose a 3D printing fixed component for a craft painting mold. Utility Model Content

[0034] Furthermore, the clamping assembly includes a concave block 3 and a positioning screw 301 at the bottom of the concave block 3, the positioning screw 301 is inserted into the corresponding mounting hole 102, and each positioning screw 301 is threadedly connected with a fastener for threaded fixation. Each group of clamping assemblies in the present technical solution is installed in a plug-in manner. According to the size of the printing mold base, multiple groups of clamping assemblies are selected to achieve multi-point clamping and fixation on the base tray plate 2. At the same time, the bottom of each group of clamping assemblies is threadedly connected by fasteners, which can enhance the installation and fixing effect of the clamping assembly on the base tray plate 2.

[0035] Furthermore, a clamping baffle 5 is provided at the front end of the clamping assembly, and a micro cylinder 4 for driving the clamping baffle 5 to extend and retract horizontally is connected to the rear end of the concave block 3 .

[0036] Furthermore, each of the clamping baffles 5 is provided with a row of elastic protective protrusions 501 at one end away from the concave block 3. By arranging the elastic protective protrusions 501 on the clamping baffles 5, when the clamping baffles 5 are clamped and fixed to the mold shell on the base tray plate 2, the elastic protective protrusions 501 will not damage the surface of the mold shell.

[0037] Furthermore, the micro-blower assembly includes a bellows 6 and a fan 601 on the top of the bellows 6. The outer bottom of the bellows 6 is connected to an air duct 602. One end of the air duct 602 passes through the interior of the corresponding concave block 3 and extends to the clamping baffle 5. An air duct pipe 502 is arranged between every two protective protrusions 501. The interior of the air duct pipe 502 is connected to the corresponding clamping baffle 5 and is connected to the protective protrusion 501. By arranging multiple groups of air duct pipes 502 on the clamping baffle 5 to connect the corresponding air ducts 602, multi-duct blowing or exhausting is performed on the outer clamping end of the mold.

[0039] The working principle of this utility model:

[0040] (1) Forming a flow duct:

[0041] Micro fan assemblies are symmetrically arranged on both sides of the printer body 1. The two groups of micro fan assemblies are connected to the corresponding clamping assemblies. One group of micro fan assemblies exhausts air, and the other group of micro fan assemblies blows air. The bellows 6 is connected to the air duct 502 in the clamping baffle 5 through the air guide duct 602. An air duct 502 is arranged between each two protective protrusions 501, so that the blowing and exhausting air form a flow air duct.

[0042] This design can form effective flow air ducts on both sides of the base tray plate 2. Through the cooperation of two fan components, one side draws air and the other side blows air. The generated airflow can effectively remove the heat and exhaust gas generated during the printing process, maintain the stability and cleanliness of the printing environment, and improve the printing quality.

[0043] (2) Multi-point clamping and fixing:

[0044] The clamping assembly includes a concave block 3, a positioning screw 301 and a fastener.

According to the size of the printing mold base, multiple sets of clamping assemblies can be selected to achieve multi-point clamping and fixing on the base tray plate 2.

[0045] This multi-point clamping and fixing design can flexibly adjust the position of the clamping component according to the size of the mold base, providing a stable fixing effect, preventing the mold from moving or loosening during the printing process, and improving printing accuracy.

[0046] (3) Protective function of protective bumps:

[0047] A row of elastic protective protrusions 501 is disposed at the front end of the clamping baffle 5 .

[0048] The elastic protective protrusion 501 can effectively protect the surface of the mold shell during the clamping process to prevent damage caused by excessive clamping force. This is especially important for protecting fine molds and extending the service life of the mold.

[0049] (4) Flexible extension and retraction of the clamping components:

[0050] The rear end of the concave block 3 is connected to a micro cylinder 4 for driving the clamping baffle 5 to extend and retract horizontally.

[0051] The micro cylinder 4 can drive the clamping baffle 5 to perform horizontal telescopic adjustment, so that the clamping assembly can clamp and release the mold quickly and flexibly, thereby improving the convenience and efficiency of operation.

[0052] (5) Stable support structure:

[0053] Positioning holes 201 are formed at the four corners of the base tray plate 2 . The support assembly includes a support column 101 inserted into the positioning hole 201 . The base tray plate 2 and the support column 101 are threadedly fixed by fasteners.

[0054] This design provides a stable support structure, ensuring the stability of the entire printing and fixing components, and will not affect the printing process due to external forces or vibrations, further improving the printing quality.

[0055] In summary, this embodiment, through the ingenious design and coordination of various structures, not only realizes the main effect of automatic cleaning of the filter and forming a flow air duct, but also has multiple beneficial effects such as multi-point clamping and fixation, protection of mold surface, flexible telescopic operation and stable support.
