Description

Technical Field

[0001] This invention belongs to the field of wax mold waxing technology, and particularly relates to an automatic wax mold waxing device for 3D hard gold production. Background Technology

[0002] The "3D" in 3D hard gold is an abbreviation for three-dimensional, meaning three-dimensional graphics. It represents a true three-dimensional space with realistic spatial distances. While both are made of gold, the new generation of 3D hard gold uses different processes in different areas—some polished, some matte—creating contrasts of light and shadow. The color layering is clearer, the three-dimensional effect is stronger, and the texture is differentiated. When touched, some areas are smooth and delicate, while others have a slightly matte feel, resulting in a rich tactile experience.

[0003] "3D hard pure gold" jewelry is a new type of product that breaks with traditional manufacturing processes, mainly produced using the "electroforming" method. It significantly improves the hardness and wear resistance of gold by modifying the gold content, pH value, working temperature, organic brightener content, and stirring speed in the electroforming solution, thus solving the shortcomings of existing electroforming gold jewelry, such as the inability to be worn or touched.

[0004] For example, Chinese patent application number CN201721207904.7 mentions an automatic wax receiving device for 3D hard gold production wax molds. Through the cooperation of an electric soldering iron and a welding fixture, it can quickly and effectively weld hand rings, reducing the labor intensity of workers and the scrap rate.

[0005] However, although the above technical solution can solder the hand ring with a soldering iron, after soldering the top of the hand ring, it needs to wait for a period of time to cool down. After cooling down, it cannot automatically flip the hand ring to solder the bottom of the hand ring, thus reducing work efficiency. Summary of the Invention

The material of the protrusions is rubber.

[0011] As a preferred embodiment of the above technical solution, the turntable has a square groove inside, which is connected to the turntable. A rectangular block is slidably connected inside the square groove, and the soldering iron is fitted inside the rectangular block. The bottom of the turntable has a number of positioning holes that are equidistantly arranged. A square block is fixedly connected to one side of the rectangular block. A positioning rod is provided inside the square block. One end of the positioning rod engages with the positioning hole, and a second spring is fitted onto the surface of the positioning rod.

[0012] As a preferred embodiment of the above technical solution, a U-shaped frame is fixedly connected to the top of the opposite sides of the two vertical plates, and a third spring is fixedly connected to the opposite sides of the U-shaped frame.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0034] Example: This invention provides an automatic wax receiving device for 3D hard gold production wax molds, such as... Figure 1-3As shown, the assembly includes a processing table 1, a limiting sleeve 2, and a soldering iron 13. A base 3 is fixedly connected to the top of the processing table 1, and the limiting sleeve 2 is placed on the base 3. Vertical plates 4 are fixedly connected to both sides of the top of the processing table 1. Electric telescopic rods 5 are fixedly connected to both sides of the interior of the processing table 1. Horizontal plates 8 are fixedly connected to the output ends of both electric telescopic rods 5, and the horizontal plates 8 are driven to rise by the electric telescopic rods 5. Arc-shaped grooves 6 are formed on the opposite surfaces of the two vertical plates 4, and these grooves communicate with the vertical plates 4. The interiors of the two arc-shaped grooves 6... A movable block 7 is slidably connected to each other. One end of the movable block 7 is slidably connected to one side of the horizontal plate 8. When the horizontal plate 8 rises, it also drives the movable block 7 to rise within the arc groove 6. When it rises to the top, the limiting sleeve 2 can be rotated 180 degrees. A wax receiving device is provided on the processing table 1 to receive wax for the wax mold used in 3D hard gold production. The limiting sleeve 2 is composed of two semicircular blocks. Both ends of one semicircular block are provided with connecting rods. There are two sets of connecting rods, with two rods in each set. The other semicircular block is fitted onto the two sets of connecting rods. On the connecting rod, the diameter of the limiting sleeve 2 can be changed. A lighting fixture is set on one side of the top of the processing table 1. The outer shell of the lighting fixture is a corrugated pipe made of stainless steel. The lighting fixture is connected to an external power source via a wire. A motor controller is set on the other side of the top of the processing table 1. The electrical controller is connected to the electric telescopic rod 5, the servo motor 11, and the soldering iron 13 via a wire. In use, the 3D hard gold bracelet wax model is placed on the base 3 and located inside the limiting sleeve 2. Then, the speed of the servo motor 11 is adjusted by the electrical controller. Then, the soldering iron 13 is preheated. After the wax is applied to the top of the bracelet, the wax application device is raised. Then, the two electric telescopic rods 5 are started by the motor controller. The two electric telescopic rods 5 drive the horizontal plate 8 to rise. When the horizontal plate 8 rises, it also drives the moving block 7 to rise in the arc groove 6. When it rises to the top, the limiting sleeve 2 can be rotated 180 degrees. Then, the wax application device is lowered to apply wax to the bottom of the bracelet.

[0035] like Figure 4-5As shown, the wax receiving device includes: a soldering iron 13; a fixed block 9 is fixedly connected to the top of the processing table 1; a lifting block 10 is slidably connected to one side of the fixed block 9; a servo motor 11 is fixedly connected to the top of the lifting block 10; a turntable 12 is fixedly connected to the output end of the servo motor 11; the servo motor 11 drives the turntable 12 to rotate; the soldering iron 13 is mounted on the turntable 12; the turntable 12 allows the soldering iron 13 to rotate one revolution; a slot 14 is provided on one side of the fixed block 9; several slots 14 are equidistantly arranged and communicate with the interior of the fixed block 9; a rectangular groove is provided on one side of the fixed block 9; the rectangular groove communicates with the interior of the fixed block 9; and first sliding grooves 15 are provided on both sides of the inner wall of the fixed block 9; several sets of first sliding grooves 15 are provided. There are two groups. Each group has a locking block 16 slidably connected between the first slide groove 15. The locking block 16 and the slot 14 engage with each other. A push rod 17 is fixedly connected to one side of the locking block 16 and located between the rectangular slots. One end of the push rod 17 extends to the outside of the lifting block 10. The push rod 17 and the lifting block 10 are slidably connected. After the soldering iron 13 is preheated, the push rod 17 is pushed backward to push the locking block 16 to move backward from the slot 14 and move both ends out of the first slide groove 15, so that the lifting block 10 can be raised and lowered. After selecting a suitable position, the push rod 17 is pulled to make the locking block 16 engage with the slot 14 again to fix the lifting block 10. Then, the servo motor 11 drives the turntable 12 to rotate, so that the soldering iron 13 can rotate one revolution to collect wax on the top of the hand ring.

[0036] like Figure 6-7As shown, a first cylinder 18 is fixedly connected to both sides of the outer wall of the limiting sleeve 2, and a second cylinder 19 is fixedly connected to the opposite face of the two moving blocks 7. A threaded rod 20 is threaded between the second cylinder 19 and the first cylinder 18. By rotating the threaded rods 20 on both sides, the first cylinders 18 on both sides can cause the limiting sleeve 2 to expand outward or contract inward, depending on the diameter of the wristband. Placement slots are provided on both sides of the inner wall of the limiting sleeve 2. A first spring 21 is fixedly connected to one side of each of the two placement slots. There are two sets of four first springs 21. A push plate 22 is fixedly connected to the other end of each set of first springs 21. A rotating shaft is provided in the middle of the push plate 22. After the push plate 22 contacts the wristband, the two ends of the push plate 22 will rotate through the rotating shaft in the middle. This forms a V-shape, increasing the contact area with the wristband. A protrusion is provided on one side of the push plate 22, with several protrusions evenly spaced. The protrusions are made of rubber and serve as an anti-slip element. When the wristband is placed inside the limiting sleeve 2, it compresses the push plates 22 on both sides. The reaction force of the first spring 21 clamps and fixes the wristband in place. After the push plate 22 contacts the wristband, the two ends of the push plate 22 rotate through the central pivot, forming a V-shape and further increasing the contact area with the wristband. If the diameter of the limiting sleeve 2 does not match the wristband, rotating the positive and negative threaded rods 20 on both sides causes the first cylinders 18 on both sides to expand the limiting sleeve 2 outwards or contract inwards, depending on the diameter of the wristband.

[0037] like Figure 8-9 As shown, a square groove is provided inside the turntable 12, which is connected to the turntable 12. A rectangular block 23 is slidably connected inside the square groove. The soldering iron 13 is fitted inside the rectangular block 23. A number of positioning holes 24 are provided at the bottom of the turntable 12 and are equidistant. A square block 25 is fixedly connected to one side of the rectangular block 23. A positioning rod 26 is provided inside the square block 25. One end of the positioning rod 26 is engaged with the positioning hole 24. A second spring 27 is fitted onto the surface of the positioning rod 26. When the diameter of the bottom limiting sleeve 2 changes, the positioning rod 26 is pulled down and the second spring 27 is squeezed, causing the positioning rod 26 to separate from the positioning hole 24. Then, the soldering iron 13 is moved through the rectangular block 23 to adjust according to the diameter of the wristband. Then, the positioning rod 26 is released and the reaction force of the second spring 27 pushes the positioning rod 26 to engage with the positioning hole 24, thus fixing the soldering iron 13.

[0038] like Figure 10As shown, a U-shaped frame 28 is fixedly connected to the top of the opposite sides of the two vertical plates 4. A third spring 29 is fixedly connected to the opposite sides of the U-shaped frame 28. There are two sets of third springs 29, with two in each set. A pressure plate 30 is fixedly connected between one end of each set of third springs 29. The opposite sides of the two pressure plates 30 are set as arc surfaces. When the moving block 7 is about to rise to the top, it will squeeze the two pressure plates 30. The pressure plates 30 will then move to both sides and squeeze the third springs 29. When the moving block 7 rises to the top, it will be between the two pressure plates 30. The reaction force of the third spring 29 will cause the two pressure plates 30 to clamp the moving block 7.

[0039] like Figure 11 As shown, each of the two vertical plates 4 has a groove on one side, and each of the two grooves has a second sliding groove 31 at the bottom. Each of the two second sliding grooves 31 has a slider 32 slidably connected inside, and the slider 32 can move through the second sliding groove 31. Each of the two sliders 32 has a rotating plate 33 rotatably connected to its top. Each of the two rotating plates 33 has a gear 34 rotatably connected to its two sides inside, and the two gears 34 mesh with each other. Each of the two gears 34 has an arc-shaped block 35 fixedly connected to its top. After the limiting sleeve 2 is rotated 180 degrees, the rotating plates 33 on both sides are rotated toward the limiting sleeve 2 and pushed inward. Then the arc-shaped block 35 is pulled outward. Through the meshing of the two gears 34, the other arc-shaped block 35 will also rotate, so that the two arc-shaped blocks 35 rotate to the outside of the rotating plate 33 and form a semicircle. Then the other rotating plate 33 is operated repeatedly, so that the two semicircular arc-shaped blocks 35 are located below the wristband for support.

[0040] Working principle: In use, the 3D hard gold bracelet wax model is placed on the base 3 and positioned within the limiting sleeve 2. Then, the soldering iron 13 is preheated. By pushing the push rod 17 backward, the locking block 16 is moved backward from the slot 14, causing both ends to move out of the first sliding groove 15, allowing the lifting block 10 to rise and fall. Once a suitable position is selected, pulling the push rod 17 again engages the locking block 16 with the slot 14, fixing the lifting block 10 in place. Then, the speed of the servo motor 11 is adjusted via the electrical controller. Then, the servo motor 11 drives the turntable 12 to rotate, so that the soldering iron 13 can rotate one revolution to collect wax from the top of the hand ring. After the wax is collected from the top of the hand ring, the wax collection device is raised, and then the two electric telescopic rods 5 are activated by the motor controller. The two electric telescopic rods 5 drive the horizontal plate 8 to rise. When the horizontal plate 8 rises, it also drives the moving block 7 to rise in the arc groove 6. When it rises to the top, the limit sleeve 2 can be rotated 180 degrees. Then the wax collection device is lowered to collect wax from the bottom of the hand ring.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
