Description

Technical Field

[0001] The utility model relates to a positioning mold, in particular to a special mold for positioning a heat transfer mobile phone shell, and belongs to the technical field of auxiliary equipment for customized processing equipment for mobile phone shells. Background Art

[0002] Heat transfer phone cases are personalized phone cases made using heat transfer technology, allowing users to design unique patterns or images based on their preferences and creativity. This personalized option allows each phone case to reflect the owner's style. Heat transfer phone cases are an excellent product that combines art and practicality. They not only provide excellent protection but also show the user's personality. They are an excellent choice for personal use or as gifts.

[0003] The heat transfer process of heat transfer mobile phone cases involves printing the designed or selected pattern on special heat transfer paper, and then transferring the pattern to the surface of the mobile phone case through a mobile phone case heat transfer machine. This process ensures that the details and colors of the pattern can be perfectly presented.

[0004] Many of the thermal transfer mobile phone cases in the existing technology are customized products. During thermal transfer, the mobile phone case to be processed needs to be placed on the mold for fixation before thermal transfer processing can be carried out. Due to the limitations of the mold's own structure, the effect is often unsatisfactory during the thermal transfer process. On the one hand, the edge of the mobile phone case is difficult to be covered by the thermal transfer film, resulting in white edge phenomenon, affecting the appearance. On the other hand, the four corners of the mobile phone case are prone to wrinkles due to the thermal transfer film covering process, resulting in non-transfer at the four corners, thereby causing white lines, affecting the integrity. Thirdly, the thermal transfer mold usually requires one mold for each mobile phone case, which has poor versatility and requires a large number of molds, which can easily cause loss, confusion, and other phenomena. Summary of the Invention

[0005] In response to the above-mentioned shortcomings of the thermal transfer mobile phone case mold in the prior art that easily causes white edges on the four sides, the utility model provides a special mold for thermal transfer mobile phone case positioning, which has vacuum adsorption grooves around the bottom of the mold body. During the thermal transfer process, the thermal transfer film can be adsorbed to the vacuum adsorption groove due to the vacuum effect, so that the thermal transfer film can be covered on the outer surface and four sides of the mobile phone case, so that the pattern and content on the thermal transfer film can be transferred to the outer surface and four sides of the mobile phone case, thereby eliminating the white edge phenomenon.

[0009] The distance between the vacuum adsorption groove and the top surface of the mold is less than or equal to the height of the internal space of the mobile phone shell to be processed.

[0010] The bottom convex edge is provided with vacuum suction ports, which are arranged corresponding to the four corners of the bottom convex edge.

[0011] At least one vacuum suction port is provided on one or both sides of the four corner sides of the bottom convex edge.

[0012] The vacuum suction port adopts an arc-shaped notch or a semicircular notch.

[0013] The top surface of the mold body is provided with a detachable and replaceable gasket, the top surface of the mold body is provided with a gasket mounting groove, the bottom of the gasket is provided with a gasket mounting boss, the gasket mounting boss is arranged in the gasket mounting groove, and the size of the gasket mounting boss is smaller than the gasket mounting groove.

[0014] The bottom of the mold body is provided with a mounting groove.

[0016] The beneficial effects of the present invention are as follows: the present invention is provided with vacuum adsorption grooves around the bottom of the mold body, and the heat transfer film can be adsorbed to the vacuum adsorption grooves due to the vacuum effect during the heat transfer process, so that the heat transfer film can be coated on the outer surface and four sides of the mobile phone case, so that the pattern and content on the heat transfer film can be transferred to the outer surface and four sides of the mobile phone case, thereby eliminating the white edge phenomenon. On the other hand, the present invention is provided with vacuum suction ports near the four corners of the bottom convex edge, so that the heat transfer film at the four corners of the mobile phone case can be stretched to both sides during the coating process, thereby eliminating the wrinkles generated by the heat transfer film during the coating process, thereby eliminating the white line phenomenon at the four corners of the mobile phone case. In addition, the present invention is provided with a gasket installation groove on the top of the mold body, and a gasket is installed in the gasket installation groove.

[0030] This embodiment is a preferred implementation of the present utility model. Other embodiments whose principles and basic structures are the same or similar to those of this embodiment are within the protection scope of the present utility model.

[0031] Please refer to the attached Figure 1 To the attached Figure 11The present invention primarily protects a mold specifically designed for positioning a heat transfer mobile phone case, which is used in conjunction with a mobile phone case heat transfer machine. The mold primarily comprises a mold body 1, which occupies the majority of the mold's volume and is primarily the portion that engages with the mobile phone case. In this embodiment, the mold body 1 is made of aluminum alloy, which is not only strong, firm, durable, and not easily deformed, but also has a fast heat conduction rate. In specific implementations, other metals or non-metallic materials with good heat resistance and thermal conductivity may also be used. When in use, the mold is placed in a mobile phone case heat transfer machine. In the present invention, the side facing upward during use is defined as a top surface 11, and the corresponding side is defined as a top surface. The top surface is used in conjunction with the mobile phone case to be processed, and the other side is defined as a bottom surface 13. The corresponding side is defined as a bottom surface, and the surrounding areas of the mold body 1 are defined as side surfaces 12. The mold body 1 includes a top surface 11, side surfaces 12, and a bottom surface 13.

[0032] In this embodiment, a vacuum adsorption groove 3 is provided at the bottom of the mold body 1. The vacuum adsorption groove 3 is an adsorption groove opened along the side surfaces of the four sides of the mold body 1. In this embodiment, the vacuum adsorption groove 3 is an annular adsorption groove opened along the side surfaces of the mold body 1. In specific implementation, it is also possible not to open a circle, as long as it can meet the adsorption requirements. Preferably, the distance between the vacuum adsorption groove 3 and the top surface of the mold is less than or equal to the height of the internal space of the mobile phone case to be processed. That is, when the mobile phone case to be processed is placed on the mold body 1, the four sides of the mobile phone case to be processed will be located at the vacuum adsorption groove 3. During the thermal transfer process, the thermal transfer film can be adsorbed to the vacuum adsorption groove, so that the thermal transfer film can be coated on the four sides of the mobile phone case, so that the pattern and content on the thermal transfer film can be transferred to the four sides of the mobile phone case, thereby eliminating the white edge phenomenon on the four sides of the mobile phone case.

[0033] In this embodiment, a bottom flange 2 is provided protruding outwardly below the vacuum suction groove 3 on the side of the mold body 1. That is, the vacuum suction groove 3 is provided between the mold body 1 and the bottom flange 2. Vacuum suction ports 4 are provided on the bottom flange 2. In this embodiment, the vacuum suction ports 4 are preferably provided near the four corners 14 of the bottom flange 2 (i.e., the mobile phone case to be processed) (not at the corners. In this utility model, since the bottom flange 2 is approximately rectangular, the four corners of the rectangle are referred to as corners 14 in this utility model. There are four corners, all of which are defined as corners 14). One or two vacuum suction ports 4 are provided for each corner 14 of the bottom flange 2. When two vacuum suction ports 4 are provided, one is provided on either side of each corner 14 of the bottom flange 2. This provides better results than providing only one vacuum suction port 4. However, providing one vacuum suction port 4 on either side of each corner of the bottom flange 2 can also achieve the desired effect, though the effect is slightly less satisfactory. During use, the suction force generated at the vacuum suction port 4 is higher than that at other positions, which allows the heat transfer film corresponding to the four corners 14 of the mobile phone case to stretch to both sides (if only one is opened at each corner of the bottom convex edge 2, it will be stretched to one side) during the wrapping process, thereby eliminating the stacking and wrinkles of the heat transfer film during the wrapping process, thereby eliminating the white line phenomenon at the four corners of the mobile phone case. Figure 11 In this embodiment, the vacuum suction port 4 preferably adopts an arc-shaped notch or a semicircular notch, and avoids sharp corners as much as possible to prevent them from puncturing the thermal transfer film and affecting the use effect. In specific implementation, the vacuum suction port 4 can also adopt other forms, such as: opening a circular hole, a strip hole, etc. on the bottom convex edge 2, and the vacuum suction port 4 can also be more than two.

[0034] The above is the simplest implementation method of the present invention, and a mold can be customized for each mobile phone. In specific implementation, the present invention can be implemented in the same or similar sizes of mobile phones, and there are other implementation methods to achieve a universal mold.

[0035] In this embodiment, the top surface of the mold body 1 is provided with a removable and replaceable gasket 5. The shape of the gasket 5 can be specifically set according to the shape of the raised portion corresponding to the position of the mobile phone camera inside the mobile phone case of different models. When in use, the gasket 5 is placed inside the mobile phone case at the position corresponding to the mobile phone camera, so that the mobile phone case camera portion can fit with the gasket 5. The gasket 5 quickly conducts heat to the mobile phone case camera portion, making it heat more evenly. At the same time, the gasket 5 can also withstand the pressure caused by the thermal transfer film on the mobile phone case, preventing the thermal transfer film from being torn during thermal transfer due to excessive space between the mold body 1 and the mobile phone case camera position, thereby affecting the transfer effect. When using the same mold to perform thermal transfer on different models of mobile phone cases, the gasket 5 that is compatible with it can be replaced.

[0036] In this embodiment, a gasket mounting groove 6 is defined on the top surface of the mold body 1, and a gasket mounting boss 7 is provided on the bottom of the gasket 5. The gasket mounting boss 7 is positioned within the gasket mounting groove 6 to limit the installation position of the gasket 5. In this embodiment, the gasket mounting boss 7 is smaller than the gasket mounting groove 6, allowing the gasket 5 to move within a certain range, thus preventing improper fit due to dimensional errors in the phone case. If the phone case does not have a groove for the phone camera, the gasket 5 can also be omitted.

[0037] In this embodiment, the bottom of the mold body 1 is provided with a mounting groove 8. This groove 8 corresponds to the shape of the boss on the mobile phone case heat transfer machine, allowing the present invention to be placed and installed in the mobile phone case heat transfer machine through the mounting groove 8. In this embodiment, the bottom of the mold body 1 is provided with an anti-fouling mechanism, which allows for easy and clear identification of the orientation of the mobile phone case to prevent misplacement and resulting lamination errors. The anti-fouling mechanism is implemented as an anti-fouling arc-shaped protrusion 9, which is located within the mounting groove 8. In practice, other anti-fouling structures may be used in place of the anti-fouling arc-shaped protrusion 9.

[0038] In this embodiment, an air guide groove can be opened in the installation groove 8, and the air guide groove is opened corresponding to the vacuum exhaust hole on the mobile phone case heat transfer machine. The air in the mobile phone case heat transfer machine can be conducted to the vacuum exhaust hole position on the mobile phone case heat transfer machine through the air guide groove to achieve the purpose of vacuuming.

[0039] The present invention is provided with vacuum adsorption grooves around the bottom of the mold body. During the thermal transfer process, the vacuum effect can adsorb the thermal transfer film to the vacuum adsorption grooves, so that the thermal transfer film can be coated on the outer surface and four sides of the mobile phone case, so that the pattern and content on the thermal transfer film can be transferred to the outer surface and four sides of the mobile phone case, thereby eliminating the white edge phenomenon. On the other hand, the present invention is provided with vacuum suction ports near the four corners of the bottom convex edge, so that the thermal transfer film at the four corners of the mobile phone case can be stretched to both sides during the coating process, thereby eliminating the wrinkles generated by the thermal transfer film during the coating process, thereby eliminating the white line phenomenon at the four corners of the mobile phone case. In addition, the present invention is provided with a gasket installation groove on the top of the mold body. A gasket is installed in the gasket installation groove. Different gaskets can be replaced according to different mobile phone models to make it fit more closely with the internal space of the mobile phone case to be processed, thereby increasing the versatility of the mold.
