Description

Technical Field

[0001] This utility model relates to the field of hot stamping plate technology, and in particular to a hot stamping component. Background Technology

[0002] Flatbed hot stamping machines offer higher stamping efficiency compared to rotary hot stamping machines. Therefore, in post-press processing, flatbed hot stamping machines have gradually replaced rotary hot stamping machines and are widely used. However, flatbed hot stamping machines have the following problem: when the stamped pattern is a solid color block larger than 10mm*10mm, the aluminum plating layer is easily peeled off, easily causing spots on the color block, severely affecting the stamping quality. This phenomenon is particularly severe when the solid color block area is larger than 15mm*15mm. Utility Model Content

[0003] Therefore, it is necessary to provide a hot stamping component to solve the above problems.

[0004] A hot stamping assembly has a solid positive image on it, a first vent hole on the side of the hot stamping assembly, and a second vent hole on the edge of the solid positive image, wherein the first vent hole and the second vent hole are connected.

[0005] In one embodiment, the hot stamping assembly includes a face plate and a base plate stacked together.

[0006] In one embodiment, the first vent is located on the upper surface of the base plate, and the second vent penetrates the front plate.

[0007] In one embodiment, the number of the second vent holes is multiple.

[0008] In one embodiment, the second vent is disposed around the edge of the solid positive image.

[0009] In one embodiment, the first vent is provided with a branch.

[0010] In one embodiment, the hot stamping assembly is made of copper.

[0011] In one embodiment, the second vent has an angle α with the horizontal plane.

[0012] In one embodiment, the side length of the solid positive image is 10mm to 100mm.

[0013] In one embodiment, heat insulation material is provided inside the first vent and the second vent.

[0014] In use, the first vent of the hot stamping assembly is connected to the air source, which can provide intermittent high-pressure gas. When the hot stamping assembly and the electroplated aluminum are in a pressurized state, the air source is closed. When the hot stamping assembly and the electroplated aluminum are in a depressurized state, the air source is open. At this time, the high-pressure gas can act on the outer surface of the electroplated aluminum through the second vent. This will produce two beneficial effects: (1) The high-pressure gas can cool the electroplated aluminum quickly, thereby causing the adhesive layer of the electroplated aluminum to change from a molten state to a solidified state quickly, which will greatly improve the adhesion of the adhesive and prevent the aluminum plating layer from being peeled off with the substrate layer to form spots. (2) It helps to separate the electroplated aluminum film from the hot stamping assembly in a timely manner, terminates the heat conduction of the hot stamping assembly to the electroplated aluminum film, and helps to prevent the formation of spots.

[0020] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is considered to be "connected" or "connected" to another element, it can be directly connected to the other element or there may be an intervening element. The terms "upper," "lower," "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] The hot stamping component 10 will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figures 1 to 3 One embodiment of the hot stamping assembly 10 is made of a single material. The upper surface of the hot stamping assembly 10 is provided with a solid positive image 101. The side of the hot stamping assembly 10 is provided with a first vent hole 102. The upper surface of the hot stamping assembly 10 is provided with a second vent hole 103, and the first vent hole 102 and the second vent hole 103 are connected.

[0024] The first vent 102 is located on the side of the hot stamping assembly 10 and is used to connect to an air source. During hot stamping, a honeycomb plate is installed on the upper platform of the hot stamping machine, the hot stamping assembly 10 is fixedly installed on the honeycomb plate, the hot stamping film is placed between the upper and lower platforms, and the packaging material is placed between the hot stamping film and the lower platform. Therefore, due to space limitations, by providing the first vent 102 on the side of the hot stamping assembly 10, lateral air intake can be achieved without modifying the hot stamping equipment, which has high practicality.

[0025] The second vent 103 is connected to the first vent 102, causing the high-pressure gas to change its direction of movement and act on the electroplated aluminum film.

[0026] Preferably, the second vent 103 is located at the edge of the solid positive image 101. This arrangement facilitates the direct application of high-pressure gas to the electroplated aluminum film near the solid positive image 101, thereby facilitating the separation of the hot stamping assembly 10 from the electroplated aluminum film.

[0027] Furthermore, there are multiple second vent holes 103, which are arranged around the edge of the solid positive image 101. This arrangement helps to improve the cooling efficiency of the electroplated aluminum film after hot stamping.

[0028] Furthermore, please refer to Figure 3 The second vent 103 has an angle α with the horizontal plane, causing the second vent 103 to tilt toward the solid positive image 101. During the hot stamping operation, the high-pressure gas blown out by the second vent 103 will directly act on the electroplated aluminum film at the corresponding position of the solid positive image 101, which helps to further improve the cooling efficiency of the electroplated aluminum film after hot stamping.

[0029] Preferably, heat insulation material (not shown in the figure) is provided in the first vent 102 and the second vent 103. By providing heat insulation material in the first vent 102 and the second vent 103, it is possible to prevent the first vent 102 and the second vent 103 from carrying away a large amount of heat from the hot stamping component 10 when blowing air. On the one hand, it can prevent the temperature of the hot stamping component 10 from fluctuating and affecting the hot stamping quality; on the other hand, it helps to reduce energy consumption.

[0030] Alternatively, the insulation materials may include, but are not limited to, ceramics, asbestos, rock wool, and fiberglass.

[0031] In another implementation, please refer to Figure 4 and Figure 5 The hot stamping assembly 10 includes a front plate 11 and a back plate 12 stacked together. A solid positive image 101 is disposed on the upper surface of the front plate 11, and a second vent 103 penetrates the front plate 11. A first vent 102 is disposed on the upper surface of the back plate 12. The front plate 11 and the back plate 12 are detachably connected by a nut. This configuration helps to reduce the processing cost of the hot stamping assembly 10.

[0032] Preferably, the first vent 102 has multiple branches on the base plate 12, and each branch communicates with at least one second vent 103. This arrangement allows the first vent 102 to retain only one air inlet, which helps to improve the connection efficiency of the air source.

[0033] Optionally, the hot stamping component 10 is made of a metal material that has good thermal conductivity and is easy to process.

[0034] Preferably, the hot stamping component 10 is made of copper, which has moderate hardness and is suitable for engraving complex patterns such as solid positive image 101.

[0035] Optionally, the thickness of the hot stamping component 10 is 5mm-8mm.

[0036] Optionally, the side length of the solid positive image 101 is 10mm to 100mm. Through testing, it has been shown that when the side length of the solid positive image 101 is 10mm to 100mm, using the aforementioned hot stamping component 10 can reduce the frequency of spot occurrence by up to 95%.

[0037] When the hot stamping assembly 10 is in use, the first vent 102 is connected to the air source, which can provide intermittent high-pressure gas. When the hot stamping assembly 10 and the electroplated aluminum are in a pressurized state, the air source is closed. When the hot stamping assembly 10 and the electroplated aluminum are in a depressurized state, the air source is open. At this time, the high-pressure gas can act on the outer surface of the electroplated aluminum through the second vent 103. This will produce two beneficial effects: (1) The high-pressure gas can cool the electroplated aluminum quickly, thereby causing the adhesive layer of the electroplated aluminum to change from a molten state to a solidified state quickly, which will greatly improve the adhesion of the adhesive and prevent the aluminum plating layer from being peeled off with the substrate layer to form spots. (2) It helps the electroplated aluminum film to separate from the hot stamping assembly 10 in a timely manner, terminates the heat conduction of the hot stamping assembly 10 to the electroplated aluminum film, and helps prevent the formation of spots.

[0038] The following are specific examples. Example

[0039] Please see Figures 1 to 3 This embodiment provides a hot stamping component 10, which is made of a single material. The upper surface of the hot stamping component 10 is provided with a solid positive image 101, the side of the hot stamping component 10 is provided with a first vent hole 102, and the upper surface of the hot stamping component 10 is provided with a second vent hole 103, and the first vent hole 102 and the second vent hole 103 are connected.

[0040] When the hot stamping assembly 10 is in use, the first vent 102 is connected to the air source, which can provide intermittent high-pressure gas. When the hot stamping assembly 10 and the electroplated aluminum are in a pressurized state, the air source is closed. When the hot stamping assembly 10 and the electroplated aluminum are in a depressurized state, the air source is open. At this time, the high-pressure gas can act on the outer surface of the electroplated aluminum through the second vent 103. This will produce two beneficial effects: (1) The high-pressure gas can cool the electroplated aluminum quickly, thereby causing the adhesive layer of the electroplated aluminum to change from a molten state to a solidified state quickly, which will greatly improve the adhesion of the adhesive and prevent the aluminum plating layer from being peeled off with the substrate layer to form spots. (2) It helps the electroplated aluminum film to separate from the hot stamping assembly 10 in a timely manner, terminates the heat conduction of the hot stamping assembly 10 to the electroplated aluminum film, and helps prevent the formation of spots. Example

[0041] The hot stamping assembly 10 provided in this embodiment is similar to the hot stamping assembly 10 provided in embodiment 1, except that: (1) the second vent 103 has an angle α with the horizontal plane, so that the second vent 103 is inclined toward the solid positive image 101. (2) heat insulation material is provided in the first vent 102 and the second vent 103.

[0042] In the aforementioned hot stamping assembly 10, because the second vent 103 is inclined towards the solid positive image 101, the high-pressure gas blown out by the second vent 103 during the hot stamping operation will directly act on the electroplated aluminum film at the corresponding position of the solid positive image 101, which helps to further improve the cooling efficiency of the electroplated aluminum film after hot stamping. By setting heat insulation material in the first vent 102 and the second vent 103, it is possible to prevent the first vent 102 and the second vent 103 from carrying away a large amount of heat from the hot stamping assembly 10 during air blowing. On the one hand, this can prevent the temperature of the hot stamping assembly 10 from fluctuating and affecting the hot stamping quality; on the other hand, it helps to reduce energy consumption. Example

[0043] Please see Figure 5The hot stamping assembly 10 provided in this embodiment is similar to the hot stamping assembly 10 provided in embodiment 2, except that: (1) the hot stamping assembly 10 includes a face plate 11 and a base plate 12 stacked together, a solid positive image 101 is disposed on the upper surface of the face plate 11, and a second vent hole 103 is disposed through the face plate 11. A first vent hole 102 is disposed on the upper surface of the base plate 12, and the face plate 11 and the base plate 12 are detachably connected by a nut. (2) The first vent hole 102 is provided with multiple branches on the base plate 12, and each branch is connected to at least one second vent hole 103.

[0044] The hot stamping assembly 10 described above, by setting up a face plate 11 and a base plate 12, helps to reduce the processing cost of the hot stamping assembly 10. By setting a branch on the first vent 102, the first vent 102 can retain only one air inlet, which helps to improve the connection efficiency of the air source.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
