Detailed Implementation

[0029] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figures 1-9 As shown, the manufacturing process for lightweight metal souvenirs includes the following steps: S1: Prepare circular metal plates and circular paper plates, wherein the circular paper plate is substrate 3. The paper plate is moldable.

[0031] S2: The metal sheet is die-cast to form an upper cover 1 or a lower cover 2, wherein the lower cover 2 has a placement groove 21 at the top and the upper cover 1 has an installation groove at the bottom.

[0032] S3: Place the lower cover 2, substrate 3 and upper cover 1 in sequence, that is, the substrate 3 is located in the placement groove 21, and the upper cover 1 covers the top of the substrate 3, and the side wall of the upper cover 1 is located between the side wall of the substrate 3 and the lower cover 2.

[0033] S4: The upper cover 1 is die-cast to form a pattern, then flipped over, and the lower cover 2 is die-cast to form a pattern. The die-casting process causes the lower cover 2, the substrate 3, and the upper cover 1 to adhere tightly together, thus forming a commemorative coin.

[0034] Therefore, in actual use, the commemorative coin is formed by combining the lower cover 2, the base plate 3 and the upper cover 1. Thus, only the outer layer is metal and the middle is made of other materials, which can reduce costs and lower the cost and selling price. This allows it to be applied in more scenarios and can be used and promoted more effectively.

[0035] Furthermore, the pattern surface needs to be colored, but the color component is oil-based pigment, which is easily affected by ambient temperature and will fade. Therefore, the present invention also includes S6: an inert base layer is provided on the pattern surface, and a mirror layer is provided on the inert base layer, and a highlight layer is provided on the mirror layer.

[0036] The inert base layer can be an epoxy zinc-rich resin, which is composed of epoxy resin, polyamide resin, ultrafine zinc powder, and isopropanol. The mirror layer is a silver ammonia solution and a potassium borohydride solution, which are sprayed onto the inert base layer. The high-gloss layer is composed of hydroxyl acrylic resin, ultra-weather-resistant pigment, and polyester resin.

[0037] Therefore, in actual use, because it is an inert base layer, it is not easily affected by ambient temperature and will not fade. Moreover, the setting of the mirror layer and the high-gloss layer makes it have a strong metallic texture and high brightness. The high-gloss colored mirror effect adds a strong decorative effect, thereby increasing its collection value.

[0038] Furthermore, in step S2, several protrusions are formed on the outer side of the lower cover 2 sidewall, and the protrusions are used to increase friction.

[0039] Meanwhile, metal materials tend to darken over long periods of circulation. Therefore, a protective layer needs to be formed on the surface of metal products to isolate them from air and prevent oxidation and corrosion of precious metals. Therefore, S5 is also included: a protective film is applied to the bottom and outer sidewalls of the lower cover 2 and the outer side of the top of the upper cover 1, and the material of the protective film is zinc oxide.

[0040] Therefore, in actual use, the protective film isolates the upper cover 1 and the lower cover 2 from the air, thereby preventing the oxidation and corrosion of precious metals.

[0041] Furthermore, in order to make the connection between the upper cover 1 and the lower cover 2 tighter and more stable, in step S2, a protrusion is formed on the outer side of the side wall of the upper cover 1, and a slot is provided on the inner wall of the placement groove 21.

[0042] Therefore, in actual use, the matching of the protrusion 11 and the slot 22 makes the connection between the upper cover 1 and the lower cover 2 more tight and stable.

[0043] like Figures 4-9 As shown, it also includes S7: a decorative ring 4 is provided on the outside of the commemorative coin, and the commemorative coin and the decorative ring 4 are connected by a pivot 5, and the main body is rotatably mounted on the pivot 5.

[0044] Therefore, in actual use, the decorative ring 4 and the rotating shaft 5, along with the rotation of the commemorative coin, add a bit of fun to the commemorative coin, making it not only beautiful but also a bit fun.

[0045] Furthermore, the decorative ring 4 and the rotating shaft 5 can be either rotatable or fixed. When the decorative ring 4 is fixedly set on the rotating shaft 5, that is, fixed, only the main body rotates; while when the decorative ring 4 is rotatably set on the rotating shaft 5, that is, both the main body and the decorative ring 4 rotate, thus making it more interesting.

[0046] Meanwhile, the structure of the pivot 5 is such that it passes directly through the middle, that is, a channel is opened in the middle of the main body so that the pivot 5 can pass through and be exposed, and the decorative ring 4 also has a hole so that the pivot 5 can pass through.

[0047] Furthermore, in step S7, the structure of decorative ring 4 can be varied. When decorative ring 4 is also made of metal, in order to reduce costs, decorative ring 4 adopts the same structure as commemorative coins, with the middle filled with other materials.

[0048] The specific structure is as follows: Figure 7 and Figure 8 As shown, the decorative ring 4 firstly includes a top cover 41 and a bottom cover 42, and a base block 43 located between the top cover 41 and the bottom cover 42. Both the top cover 41 and the bottom cover 42 are made of metal. The bottom cover 42 has a connecting groove 421 on its top, and the base block 43 is located in the connecting groove 421. The top cover 41 covers the top of the base block 43, and the side wall of the top cover 41 is located between the side walls of the base block 43 and the bottom cover 42.

[0049] Therefore, in actual use, by setting the base block 43 and combining the base block 43 with the top and bottom covers to form the decorative ring 4, only the outer layer is metal and the middle is other materials, thus reducing costs and lowering the cost and selling price.

[0050] like Figure 9 As shown, besides making the decorative ring 4 metal, it can also be made with lights to enhance its visual appeal. The specific structure is as follows: First, the decorative ring 4 includes a top cover 41 and a bottom cover 42. The top cover 41 is made of transparent material. A light strip 9, a circuit board 6, and a power supply 7 are arranged between the top cover 41 and the bottom cover 42. A sound-sensitive switch 8 is installed on the circuit board 6, and the circuit board 6 is electrically connected to the light strip 9 and the power supply 7 respectively.

[0051] Therefore, in actual use, the sound-sensing switch 8 detects sound and sends information to the circuit board 6, which in turn illuminates the light strip 9, thus increasing its visual appeal. Furthermore, even if the commemorative coin is dropped in a dark environment, the illuminating light strip 9 can help locate it.

[0052] Furthermore, to make it more interesting, decorative plates are included. The specific structure is as follows: First, S8 is included: Rotatable decorative plates 10 and 20 are respectively set on the upper and lower sides of the commemorative coin, and decorative plates 10 and 20 are interlocked with each other.

[0053] Meanwhile, the decorative plate 10 includes a base 101 and a cover 102, with the cover 102 located at the opening of the base 101. The base 101 has a groove 103, and a limiting ring 104 is provided in the groove 103, with a ball bearing inside the limiting ring 104.

[0054] Therefore, in actual use, when the commemorative coin is rotated, the ball bearings are moved by gravity and push the decorative disc 10 to rotate, thus further adding interest to the commemorative coin.

[0055] The structure of decorative disc 20 is the same as that of decorative disc 10, including mounting base 201 and top cover 202, and ball bearings are provided in the same position, so that two forces drive decorative disc 10 and decorative disc 20 to rotate respectively.

[0056] Furthermore, the structure in which decorative plate 10 and decorative plate 20 are interlocked is as follows: First, a mounting post 105 is provided at the bottom of the base 101, and the mounting post 105 is hollow. Then, a mounting post 203 is provided at the top of the mounting base 201. The connection structure between decorative plate 10 and decorative plate 20 is achieved by mounting post 203 being located inside the mounting post 105 and interlocking with it.

[0057] like Figures 10-13 As shown, a lightweight metal souvenir production equipment is used to produce commemorative coins as described above, and includes a base plate 80, on which a placement platform 30 is provided, and die-casting devices 40 are provided on the front and rear sides of the placement platform 30, and limiting members 50 are provided on the left and right sides of the placement platform 30.

[0058] Meanwhile, a space for placing commemorative coins is formed between the two limiting members 50, and a moving component 60 is provided between the limiting member 50 and the base plate 80, and the limiting member 50 is rotatably mounted on the moving component 60.

[0059] Furthermore, the movable component 60 can be moved back and forth on the base plate 80, and the movable component 60 includes an outer rod 601 and an inner rod 602, and the inner rod 602 can be moved up and down on the outer rod 601, and the inner rod 602 is connected to the limiting member 50.

[0060] Therefore, in actual use, the commemorative coin is moved and flipped by the matching of the limiting component 50 and the moving component 60.

[0061] The limiting member 50 is a semi-circular ring, and a connecting rod 501 is provided between the limiting member 50 and the inner rod 602, and the connecting rod 501 is rotatably mounted on the inner rod 602.

[0062] Furthermore, the rotation of the limiting member 50 and the movement of the inner rod 602 are driven by a cylinder, and the movement of the moving component 60 is guided by a guide structure, that is, a track 801 is provided on the base plate 80, and the outer rod 601 moves along the track 801.

[0063] Furthermore, in order to ensure that the movement is in the appropriate place, it can be done by setting a time or by using a sensor. The structure of the sensor is as follows: First, processing position one and processing position two are respectively set at both ends of the placement table 30, and sensor one is set on the side wall of the placement table 30 between processing position one and processing position two. Sensor two is set on the side of the inner rod 602 near the placement table 30, and the distance from sensor two to the top of the inner rod 602 is equal to or greater than half the width of the limiting member 50.

[0064] Meanwhile, a sensor three is installed on the top of the placement table 30 between processing position one and processing position two, and a sensing element adapted to sensor three is installed on the side of the limiting member 50 away from the placement table 30. The inner rod 602 moves under the drive of the first driving source 701, and the first driving source 701 is electrically connected to sensor one and sensor three respectively. The limiting member 50 rotates under the drive of the second driving source 702, and the second driving source 702 is electrically connected to sensor two.

[0065] Therefore, in actual use, when sensor one detects the moving component 60, drive source one 701 drives the inner rod 602 to move upward, and when sensor two no longer detects the placement platform 30, drive source two 702 drives the limiting component 50 to rotate, and when sensor three detects the sensing component, drive source one 701 drives the inner rod 602 to move downward.

[0066] Furthermore, after the commemorative coin is moved to processing position two and die-casting is completed, it needs to be removed. At this time, the inner rod 602 needs to be moved down. The specific structure is as follows: First, processing position one and processing position two are respectively set at both ends of the placement platform 30. The placement platform 30 has a groove 301 corresponding to the limiting member 50 at processing position two. The die-casting device 40 includes a base frame 401 and a pressure head 402 that is movably set on the base frame 401. The base frame 401 has a sensor four set on the side near the placement platform 30 and corresponding to the height of the top of the commemorative coin. At the same time, the inner rod 602 moves under the drive of the drive source one 701, and the drive source one 701 is electrically connected to the sensor four. Therefore, in actual use, when sensor four detects that the pressure head 402 is separated from the commemorative coin, drive source one 701 drives the inner rod 602 to move downward.

[0067] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. However, the present invention is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of the present invention, and all such changes and modifications fall within the scope of the claimed invention.
