Description

Technical Field

[0001] The present invention relates to the technical field of metal 3D printers, and in particular to a metal 3D printer forming die removal device. Background Art

[0002] SLM technology was first proposed by the Fraunhofer Institute in Germany in 1995. This technology converts laser energy into heat energy to shape metal powder. The main difference from SLS (selective laser sintering) is that the metal powder is completely melted during the SLM process; the SLM workflow includes the laser selectively irradiating the powder above the laid powder, and the metal powder is heated until it is completely melted and then formed. Then the piston lowers the workbench by one unit, and a new layer of powder is spread on the current layer that has been formed. The equipment calls in the data of the new layer section for laser melting and bonding with the previous layer section. This process is repeated layer by layer until the entire object is formed.

[0003] However, when removing large workpieces, existing 3D printers cannot facilitate workers to remove the workpieces. Due to the small internal space, it is not conducive to multiple people to cooperate in removal. Summary of the invention

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1

[0030] Reference Figure 1-5 , a metal 3D printer forming mold removal device is provided, comprising a printer body 100; a support plate 101, which is arranged inside the printer body 100; a mounting component 200, which comprises a guide component 201 arranged at the lower part of the printer body 100, a limit component 202 arranged inside the guide component 201, and a pop-up component 203 arranged at one side of the guide component 201; a trigger component 300, which comprises a linkage component 301 arranged at the upper part of the printer body 100, and a movable component 302 arranged inside the guide component 201 and connected to the linkage component 301;

[0031] The support plate 101 is movably arranged inside the wire assembly and can only move in the Z-axis direction. Through the cooperation of the guide assembly 201 and the limit assembly 202, the support plate 101 can be stably installed inside the printer body 100, so that during the printing process, the support plate 101 can only move inside the guide assembly 201 and then through the cooperation between the linkage assembly 301 and the movable assembly 302. After printing is completed, through the cooperation between the linkage assembly 301, the movable assembly 302 and the pop-up assembly 203, the support plate 101 can be moved out of the printer body 100, which is convenient for workers to take out.

[0032] Specifically, the printer body 100 includes a powder supply bin 100a and a printing bin 100b; wherein, the printer body 100 adopts the SLM-3D printing process, a powder supply lift is provided below the powder supply bin 100a, a printing lift is provided below the printing bin 100b, and a laser, a lens and a polarizer are provided above the printer body 100. The SLM-3D printing process is that when the powder scraper plate 301b drives the printing powder to the printing bin 100b, 3D printing is completed by a laser beam. After completing one layer, the printing platform moves downward a little to complete the subsequent printing process.

[0033] Furthermore, the guide assembly 201 includes a guide frame 201a arranged inside the powder supply bin 100a and the printing bin 100b, a slide rail 201b arranged below the guide frame 201a, and an L-shaped slide plate 201c arranged inside the slide rail 201b. The guide frame 201a ensures that the support plate 101 can only move along the Z axis inside the guide frame 201a. When the support plate 101 is inside the slide rail 201b, the support plate 101 will drive the L-shaped slide plate 201c to slide in the slide rail 201b.

[0034] Furthermore, the limiting assembly 202 includes a first wedge block 202a arranged inside the slide rail 201b, a moving rod 202b arranged below the first wedge block 202a, a locking piece 202c arranged below the moving rod 202b, a first spring 202d arranged below the locking piece 202c, and a cylinder 202e arranged on the outside of the moving rod 202b. When the L-shaped slide bar moves from the outside to the inside, it hits the first wedge block 202a, and the first wedge block 202a will move downward. When the L-shaped slide bar passes completely, the first wedge block 202a will pop out due to the locking piece 202c, thereby limiting the support plate 101.

[0035] Furthermore, the locking member 202c includes a connecting slot column 202c-1 arranged below the moving rod 202b, a limiting slot plate 202c-2 arranged on the outside of the connecting slot column 202c-1, a spring piece 202c-3 arranged on one side of the limiting slot plate 202c-2, and a locking slot 202c-4 arranged on the cylinder 202e; wherein, the spring piece 202c-3 cooperates with the locking slot 202c-4, and the moving rod 202b hits the connecting slot column 202c-1, so that the limiting slot plate 202c-2 compresses the spring piece 202c-3 downward, so that the spring piece 202c-3 enters the locking slot 202c-4 to complete the locking; when the support plate 101 slides into the printer body 100, the compression length is insufficient, so the spring piece 202c-3 will not enter the locking slot 202c-4, so that the first wedge block 202a can pop out.

[0036] Furthermore, the ejection assembly 203 includes a compression spring 203 a disposed on one side of the L-shaped slide plate 201 c , and the compression spring 203 a can drive the support plate 101 to slide out of the printer body 100 through the L-shaped slide plate 201 c .

[0037] Example 2

[0038] Reference Figure 1-6This embodiment is different from the first embodiment in that: the linkage assembly 301 includes a slide groove 301a arranged inside the printer body 100, a scraper plate 301b arranged inside the slide groove 301a, a second wedge block 301c and a third wedge block 301d arranged on both sides of the scraper plate 301b, and a linkage plate 301e arranged below the second wedge block 301c and the third wedge block 301d; wherein, the descending depth of the second wedge block 301c is greater than the descending depth of the third wedge block 301d.

[0039] Specifically, the movable component 302 includes a connecting plate 302a arranged below the linkage plate 301e, and a trigger plate 302b arranged below the connecting plate 302a; wherein the trigger plate 302b is located directly above the first wedge block 202a, and a sliding groove 302c for sliding of the connecting plate 302a and the linkage plate 301e is arranged inside the printer body 100.

[0040] When the scraper plate 301b contacts the second wedge block 301c, the second wedge block 301c will move downward, thereby driving the linkage plate 301e to move downward, thereby driving the connecting plate 302a to move, thereby driving the linkage plate 301e to move, so that after the trigger plate 302b contacts the first wedge block 202a, the first wedge block 202a can be popped out, and when the scraper plate 301b contacts the third wedge block 301d, although the operation principle is the same as the second wedge block 301c, due to insufficient depth, the first wedge block 202a can be contacted, but the first wedge block 202a cannot be compressed. The trigger plate 302b and the first wedge block 202a form a limiting space to ensure that no lateral movement occurs before the support plate 101 enters the guide frame 201a.

[0041] The rest of the structure is the same as that of Example 1.

[0042] Example 3

[0043] Reference Figure 1-7 This embodiment is different from the above embodiments in that a limit plate 401 is provided below the slide rail 201b, a telescopic rod 402 is provided between the top of the support plate 101 and the slide rail 201b, and the limit plate 401 is fixedly connected to one end of the telescopic rod 402.

[0044] Specifically, a scale line 403 is set above the telescopic rod 402, and a trigger sensor 404 is set on one side of the scale line 403; wherein the trigger sensor 404 is connected to the lifting rod electrical signal inside the printer body 100, and the trigger condition of the sensor can be set according to the height of the printed object, so that the lifting rod can be lowered to the trigger condition and then the workpiece is ejected, thereby protecting the workpiece.

[0045] The rest of the structure is the same as that of Example 2.
