Description

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese application filed on April 25, 2025, with application number CN 2025105397311, entitled "Vacuum heat transfer machine, mold and assembly thereof, wiring mechanism, shielding element and method", the contents of which are considered part of the disclosure of this application and are incorporated herein by reference in their entirety. Technical Field

[0003] This application belongs to the technical field of vacuum heat transfer equipment, specifically a vacuum heat transfer mold with adjustable lateral dimensions. Background Technology

[0004] Vacuum heat transfer machines are processing equipment that transfer patterns through the combined action of heat and negative pressure. They mainly consist of a machine body with a transfer chamber and an openable cover. In operation, the object to be transferred (such as a mobile phone case) is placed on a mold inside the transfer chamber, and then a transfer film with the pattern is placed over the chamber. After the cover is closed, the machine uses a vacuum system to evacuate the transfer chamber, causing the film to tightly wrap around the object, while the heat from the chamber completes the pattern transfer. However, existing molds used for heat transfer generally adopt a fixed, integral structure, and their lateral dimensions such as length and width cannot be adjusted, resulting in insufficient equipment adaptability. When heat transferring objects of different sizes, users need to purchase molds of different sizes, increasing operating costs. Summary of the Invention

[0005] The purpose of this application is to overcome the limitation that the lateral dimensions of existing heat transfer molds are fixed and cannot be adjusted, and to provide a vacuum heat transfer mold consisting of a body and a movable and adjustable adjustment component, so as to change the lateral dimensions of the vacuum heat transfer mold by manipulating the adjustment component to adapt to loading different sizes of transfer objects.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] A vacuum heat transfer mold includes a body, at least one adjusting member, at least one selectively configurable filling member, and an elastic member. The at least one adjusting member is movably arranged on a side of the body along at least one lateral dimension of the vacuum heat transfer mold. The at least one filling member is used to fill at least a portion of a gap. The gap includes one or more of the following: at least a portion of the gap between the body and an adjacent adjusting member; at least a portion of the gap between two adjacent adjusting members when two or more adjusting members are configured; the configured filling member, the body, and the adjusting member at least define a portion of a bearing surface of the vacuum heat transfer mold; the elastic member acts on the adjusting member, causing the adjusting member to move in a direction that increases the lateral dimension of the vacuum heat transfer mold in response to the elastic member.

[0008] Compared with existing technologies, the vacuum heat transfer mold provided in this application includes a body and at least one movable adjusting component. The adjusting component can be operatively adjusted to change at least one lateral dimension of the vacuum heat transfer mold, thereby allowing adjustment according to the specifications of the object to be transferred to adapt to objects of different sizes, improving its versatility and reducing the cost of the transfer mold for users. Simultaneously, under the action of the elastic member, the adjusting component defaults to moving in the direction of increasing the lateral dimension, ensuring that the vacuum heat transfer mold always maintains an open tendency, ensuring that the object to be transferred loaded onto the vacuum heat transfer mold is securely held in place, preventing displacement during the heat transfer process, and guaranteeing the quality and accuracy of the heat transfer. Furthermore, by filling the gaps between the body and the adjusting component, and between two adjacent adjusting components, a filling member can be used to block the gaps and provide support for the object to be transferred, preventing negative pressure from directly adsorbing the object through the gaps.

[0009] Furthermore, the bottom of the main body and the adjusting component are respectively constructed with air inlet channels forming air inlets on the side of the transfer mold. The lower side of the air inlet channel is open. The above arrangement facilitates the flow of gas so as to extract air during the vacuum heat transfer process.

[0010] Furthermore, it also includes a guide structure for guiding the movement of the adjustment component, the guide structure being constructed between one or more of the following structures: between the body and the adjacent adjustment component; or between two adjacent adjustment components when two or more adjustment components are configured; the guide structure includes a guide gap constructed on one and a guide portion constructed on the other, the guide portion being movably inserted into the guide gap. Providing the above-mentioned guide structure facilitates the movement of the adjustment component, making its movement smoother and preventing jamming.

[0011] Furthermore, the surface of the guide gap is constructed with guide ribs that make movable contact with the upper and lower end faces of the guide portion. The guide ribs not only support the guide portion, but also have a smaller contact area and less friction compared to surface contact, resulting in smoother movement of the guide portion.

[0012] Furthermore, the inner side of the guide portion has an assembly space, and the guide gap has a fixing protrusion that is inserted into the assembly space. The elastic member is installed in the assembly space, with one end of the elastic member fixed relative to the fixing protrusion and the other end abutting against one end of the assembly space opposite to the fixing protrusion. The way the elastic member is arranged facilitates assembly.

[0013] Furthermore, the adjustment component is provided in one unit, and the adjustment component is constructed with a support portion that is retractably disposed on the main body. The filling member is at least partially detachably mounted on the upper side corresponding to the support portion. Alternatively, the adjustment component is provided in two or more units, and the adjustment component is constructed with a support portion that is retractably disposed on an adjacent adjustment component or the main body. The filling member is at least partially detachably mounted on the upper side corresponding to the support portion. The support portion can support the filling member.

[0014] Furthermore, the system includes a selectively configurable cover for covering the support surface of the transfer mold. The cover further seals the gaps between the filling member, the body, and the adjusting component, preventing negative pressure from adsorbing the material to be transferred and affecting the quality of the heat transfer. Preferably, the cover is made of a high-temperature resistant material; and / or, the thickness of the cover is less than or equal to 2 mm; and / or, the cover is placed or adhered to the upper end of the support surface of the transfer mold.

[0015] Furthermore, the side structure of the body, adjusting component, and filling component has an inwardly recessed clearance step formed at the bottom side of the vacuum heat transfer mold. The clearance step can be used to avoid the limiting edge at the edge of the object to be transferred, especially when the object to be transferred is a mobile phone case, it is used to avoid the limiting edge set at the edge of the mobile phone case for locking onto the edge of the mobile phone screen. Through the above setting, the vacuum heat transfer mold and the object to be transferred can fit more closely, making the object to be transferred easier to assemble and disassemble.

[0032] The specific embodiments of this application are described below with reference to the accompanying drawings.

[0033] See Figure 1 , Figure 2 , Figure 3 and Figure 4This embodiment provides a vacuum heat transfer mold a for use in a vacuum heat transfer machine, used for mounting protective cases such as mobile phone cases onto the mold to support the heat transfer of such workpieces in the vacuum heat transfer machine. Specifically, the mobile phone case is mounted on the vacuum heat transfer mold, such as... Figure 1 As shown, the vacuum heat transfer machine includes a body 1, a cover 2, and a heating element (not shown). The body 1 has a transfer cavity 100 with an open upper side. The cover 2 can close the transfer cavity 100. In some specific embodiments, the cover 2 is rotatably connected to the body 1, allowing the user to open or close the transfer cavity 100 by flipping the cover 2. The heating element provides heat to at least the transfer cavity 100. The body 1 is equipped with a vacuum system (not shown) communicating with the transfer cavity 100. The vacuum system involved in this application includes a pump body and pipelines communicating with the pump body and the transfer cavity 100. The heating element involved in this application can be a heating tube or other heating elements applicable in the prior art.

[0034] like Figure 1 The vacuum heat transfer machine shown in this application has a vacuum heat transfer mold a installed in the transfer cavity 100 of the vacuum heat transfer machine 1 during use. See also... Figure 2 and Figure 3 As shown, a vacuum heat transfer mold a includes a body 6, at least one adjusting member 7, at least one selectively configurable filling member 8, and an elastic member a01. The at least one adjusting member 7 is movably arranged along at least one lateral dimension (x, y) of the vacuum heat transfer mold a on the side of the body 6. The at least one filling member 8 is used to fill at least a portion of a gap, including one or more of the following: at least a portion of the gap between the body 6 and its adjacent adjusting member 7; and at least a portion of the gap between two adjacent adjusting members 7 when two or more adjusting members 7 are configured. The configured filling member 8, body 6, and adjusting member 7 at least define a portion of the bearing surface a06 of the vacuum heat transfer mold, the bearing surface a06 being used to support the upper side of the object to be transferred when it is fitted onto the vacuum heat transfer mold. The term "at least one" in this patent refers to one, two, or more than two objects.

[0035] See Figure 5 The elastic member a01 acts on the adjusting member 7, causing the adjusting member 7 to move in the direction of increasing the lateral dimension of the vacuum heat transfer mold in response to the elastic member a01. That is, it provides an elastic force to the adjusting member 7 so that the adjusting member 7 tends to move in the direction of increasing the lateral dimension of the vacuum heat transfer mold.

[0036] Existing transfer molds used in vacuum heat transfer machines are typically a single, integral structure. Their lateral dimensions, especially length and width, are not adjustable, resulting in poor versatility and an inability to accommodate various sizes of materials to be transferred. This forces users to spend more money to purchase transfer molds of other sizes. To address this, the vacuum heat transfer mold of this application includes a body 6 and at least one movable adjusting component 7. The adjusting component 7 can be controllably adjusted to change at least one lateral dimension (x, y) of the vacuum heat transfer mold a, allowing it to be adjusted according to the specifications of the materials to be transferred, thus adapting to different sizes, improving its versatility, and reducing the cost to users for the transfer mold. Simultaneously, under the action of the elastic member a01, the adjusting component 7 defaults to moving in the direction of increasing the lateral dimension (x, y), keeping the vacuum heat transfer mold a constantly open, ensuring that the materials loaded onto the vacuum heat transfer mold a are securely held in place, preventing displacement during the heat transfer process, and guaranteeing the quality and accuracy of the heat transfer.

[0037] Furthermore, when the lateral dimensions (x, y) of the vacuum heat transfer mold a need to be increased, gaps may occur between two adjacent adjusting components 7 and between the adjusting component 7 and the body 6. During operation, negative pressure will draw the object to be transferred downward through these gaps, causing local areas of the object to be drawn downward, resulting in an uneven surface. Consequently, the transfer film cannot perfectly adhere to the surface of the object, thus affecting the transfer quality. To address this, the vacuum heat transfer mold a of this application fills at least one filling member 8 between the body 6 and the adjusting component 7, and between two adjacent adjusting components 7. When the gaps occur, the filling member 8 can block the gaps, ensuring that the vacuum heat transfer mold a can better support the object to be transferred and preventing negative pressure from directly drawing the object downward through the gaps, causing surface depression and deformation that affects the transfer quality. Therefore, the filling member 8 of this patent makes the vacuum heat transfer mold a more suitable for vacuum environments, especially for use in vacuum heat transfer machines.

[0038] For the filling member 8 to fill at least part of the gap, including but not limited to the following situations: the filling member 8 can completely fill the gap, or it can leave part of the gap as an adjustment margin for the adjustment member 7 to accommodate more sizes of transfer materials.

[0039] See Figure 17In one embodiment, a selectively configurable cover a06 is also included, which covers the bearing surface a6 of the vacuum heat transfer mold a. When a gap is formed between the adjusting component 7 and the body 6 due to the adjustment of the lateral dimensions, the gap can be blocked by directly covering the bearing surface a6 of the vacuum heat transfer mold a with the cover a06, thus preventing negative pressure adsorption of the object to be transferred, and therefore no additional filling component 8 is needed. In practical applications, the cover a06 can be directly placed or adhered to the upper end of the bearing surface a6, and then the object to be transferred, such as a mobile phone case, can be placed on the vacuum heat transfer mold a with the cover a06. Preferably, the cover a06 is made of a high-temperature resistant material; to avoid the cover a06 being too thick and affecting the fit between the object to be transferred and the vacuum heat transfer mold a, the thickness of the cover a06 is less than or equal to 2 mm; preferably, the cover a06 is configured as a high-temperature resistant tape or Teflon tape. Of course, the vacuum heat transfer mold a of this application can be provided with a filling member 8 and a covering member a06 at the same time. Specifically, the filling member 8 is filled into the gap first, and then the covering member a06 is covered onto the bearing surface a6 of the transfer mold, so as to better cover the gap between the filling member 8, the body 6 and the adjusting member 7.

[0040] See Figure 9 The side structure of the main body 6, the adjusting component 7, and the filling component 8 has a relief step a05 formed inwardly at the bottom side of the vacuum heat transfer mold a. The object to be transferred, such as a mobile phone case, usually has a limiting edge that is fixed to the edge of the mobile phone screen at its edge. In order to better fit such a mobile phone case, the vacuum heat transfer mold a is constructed with the above-mentioned relief step a05 to avoid the limiting edge, so that the vacuum heat transfer mold a and the object to be transferred fit more closely and the object to be transferred is easier to assemble and disassemble.

[0041] See Figure 2 , Figure 3 and Figure 10 The adjusting component 7 is constructed with a support portion 9 that is retractably disposed on the adjusting component 7 or the body 6. The filling member 8 is at least partially detachably mounted on the upper side corresponding to the support portion 9. The support portion 9 is used to support the filling member 8 and further support the object to be transferred from the influence of negative pressure.

[0042] See Figure 5 and Figure 12In one embodiment, the elastic member a01 is configured as a spring. By setting the elastic member a01, it is ensured that the vacuum heat transfer mold a is always in contact with the inside of the object to be transferred, ensuring a tight fit between the mold and the object and preventing displacement of the object. When the object to be transferred is not fitted, the elastic member a01 causes the adjusting member 7 to move to adjust the lateral dimension (x, y) of the transfer mold to the maximum. When the object to be transferred is fitted, the object pushes against the adjusting member 7, and the adjusting member 7 adaptively compresses the elastic member a01 according to the size of the object to be transferred, thereby adaptively adjusting the lateral dimension (x, y) of the transfer mold to fit the internal space of the object to be transferred.

[0043] See Figure 6 The bottom of the main body 6 and the adjusting component 7 are respectively constructed with an air inlet channel a03 on the side of the vacuum heat transfer mold a, and the air inlet a02 is formed therein. The lower side of the air inlet channel a03 is open, and the air inlet channel a03 is provided to allow airflow to pass through, so as to ensure vacuuming efficiency.

[0044] See Figure 5 , Figure 7 and Figure 12 It also includes a guide structure 5 for guiding the movement of the adjustment component 7. The guide structure 5 is constructed between one or more of the following structures: between the body 6 and the adjacent adjustment component 7, and between two adjacent adjustment components 7. The guide structure 5 includes a guide gap 51 constructed on one and a guide portion 52 constructed on the other. The guide portion 52 is movably inserted into the guide gap 51. The guide structure 5 facilitates the movement adjustment of the adjustment component 7. Preferably, the surface of the guide gap 51 is constructed with guide ribs 501 that movably contact the upper and lower end faces of the guide portion 52. The guide ribs 501 not only support the guide portion 52, but also, compared to surface contact, have a smaller contact area and less friction, resulting in smoother movement of the guide portion 52.

[0045] In one specific embodiment, regarding the arrangement of the guide structure 5 described above, the guide gap 51 is provided on the body 6, and the guide portion 52 is provided on the adjacent adjusting member 7; or, the guide portion 52 is provided on the body 6, and the guide gap 51 is provided on the adjusting member 7. The positions of the guide gap 51 and the guide portion 52 can be interchanged for the adjacent adjusting member 7.

[0046] Preferably, the guide portion 52 is connected to the end of the corresponding support portion 9, and the guide portion 52 and the support portion 9 on the same adjusting component 7 form an integrated structure.

[0047] See Figure 5 and Figure 12In one specific embodiment, the main body 6 and at least part of the adjustment component 7 are respectively formed by a separate bottom cover a06 and a main component a07 detachably connected, and the air intake channel 03 is at least constructed on part of the bottom cover a06.

[0048] See Figure 5 and Figure 12 The guide portion 52 has an assembly space 502 on its inner side. The guide gap 51 has a fixing protrusion 503 that inserts into the assembly space 502. An elastic member a01 is installed in the assembly space 502. One end of the elastic member a01 is fixed relative to the fixing protrusion 503, and the other end abuts against the end of the assembly space 502 opposite to the fixing protrusion 503. This arrangement integrates the elastic member a01 and the guide portion 52, effectively utilizing the space between structures, making the structure more compact and occupying less space.

[0049] The following are specific examples of two transfer molds:

[0050] As an example of the first type of vacuum heat transfer mold:

[0051] See Figures 9 to 12 The vacuum heat transfer mold a includes a body 6 and a first adjustment component 71 movably coupled to one side of the body 6. The body 6 and the first adjustment component 71 at least define a portion of the bearing surface a6 of the vacuum heat transfer mold a. The first adjustment component 71 movably adjusts a first lateral dimension y of the vacuum heat transfer mold a. In this embodiment, the vacuum heat transfer mold a is provided with a first adjustment component 71. By adjusting the first adjustment component 71, the first lateral dimension y of the vacuum heat transfer mold a can be adjusted, making it suitable for applications where the size variation of the vacuum heat transfer mold a is relatively simple.

[0052] See Figure 10 It also includes a selectively configurable first filling member 81, which fills at least a portion of the gap between the body 6 and the first adjusting member 71. The configured first filling member 81 defines a portion of the bearing surface a6 of the vacuum heat transfer mold a. The first filling member 81 ensures that the vacuum heat transfer mold a can better support the object to be transferred, preventing negative pressure from directly adsorbing the object downwards through the gap and causing surface depressions and deformation, thus affecting the transfer quality. Figure 15 The first filling member 81, indicated by the dashed line, is a schematic diagram of its arrangement between the body 6 and the first adjusting member 71.

[0053] See Figure 10 and Figure 12The first adjusting member 71 has a telescopically detachable first support portion 91 on the body 6. The first filling member 81 is configured as a strip structure mounted on the upper end of the first support portion 91, with both ends bent downwards to form flanges 90 that are engaged with the sides of the first support portion 91. The flanges 90 define at least a portion of the side surface of the vacuum heat transfer mold a. The first support portion 91 facilitates the installation of the first filling member 81, and the flanges 90 limit the position of the first filling member 81.

[0054] See Figure 12 The body 6 has an internal structure with a first guide gap 511 extending along a first lateral dimension y. The first adjusting member 71 has a first guide portion 521 movably inserted into the first guide gap 511. The first guide portion 521 is preferably connected to the first support portion 91. In a specific embodiment, the body 6 has an internal structure with a limiting boss a04, and the first guide gap 511 is formed between the outer surface of the limiting boss a04 and the inner surface of the body 6. This arrangement allows the first adjusting member 71 to move more smoothly. In a specific embodiment, the body 6 is composed of a separate bottom cover a06 and a main member a07 detachably connected, with the limiting boss a04 constructed on the bottom cover 61.

[0055] See Figure 12 The first guide portion 521 has an assembly space 502 on its inner side. The first guide gap 511 has a fixing protrusion 503 that inserts into the assembly space 502. An elastic member a01 is disposed within the assembly space 502, causing the first adjusting component 71 to move in a direction that increases the first lateral dimension y of the vacuum heat transfer mold a. One end of the elastic member a01 is fixed relative to the fixing protrusion 503, and the other end abuts against the end of the assembly space 502 opposite to the fixing protrusion 503. This arrangement integrates the elastic member a01 with the first guide portion 521, effectively utilizing the space between structures, making the structure more compact and occupying less space.

[0056] See Figure 9 , Figure 10 , Figure 12In a specific application scenario, when it is necessary to increase the first lateral dimension y of the vacuum heat transfer mold a, the first adjusting member 71 is moved away from the body 6 along the direction of the first lateral dimension y, so that the first support 91 extends out of the body 6, and the first filling member 81 is placed on the first support 91. The body 6, the first adjusting member 71, and the first filling member 81 together define at least a portion of the bearing surface a6 of the vacuum heat transfer mold a. The object to be transferred is fitted onto the vacuum heat transfer mold a, so that its surface is supported on the bearing surface a6 of the vacuum heat transfer mold a. In this embodiment, the first adjusting member 71 moves away from the body 6 under the action of the elastic member a01. The vacuum heat transfer mold a in the above state Based on this, when it is necessary to reduce the first lateral dimension y of the vacuum heat transfer mold a, the first adjusting component 71 is pushed towards the side closer to the body 6 along the direction of the first lateral dimension y, reducing the gap between the first adjusting component 71 and the body 6. The smaller first filling component 81 is then replaced, which can reduce the first lateral dimension y of the vacuum heat transfer mold a. Of course, the first lateral dimension y of the vacuum heat transfer mold a can be adjusted to the minimum size by adjusting the first adjusting component 71 to be close to the body 6 and removing the first filling component 81. For example, when a mobile phone case is placed on the transfer mold, the mobile phone case pushes the first adjusting component 71 to compress the elastic component a01, thereby adaptively adjusting the first lateral dimension y of the vacuum heat transfer mold a.

[0057] As an example of the second type of vacuum heat transfer mold:

[0058] See Figures 4 to 7 The vacuum heat transfer mold a includes a body 6 and three adjusting components 71, 72, and 73 movably coupled to the sides of the body 6. The first adjusting component 71 is movably coupled to a first side of the body 6, the second adjusting component 72 is movably coupled to a second side of the body 6, and the third adjusting component 73 is movably coupled between the first adjusting component 71 and the second adjusting component 72. The third adjusting component 73 can be controlled by the first adjusting component 71 to adjust the first lateral dimension y of the vacuum heat transfer mold a, and can be controlled by the second adjusting component 72 to adjust the second lateral dimension x of the vacuum heat transfer mold a. In this embodiment, the vacuum heat transfer mold a is provided with three adjusting components 7, thus allowing for flexible adjustment of the size of the vacuum heat transfer mold a, making its size more diverse and suitable for application scenarios requiring vacuum heat transfer molds a of various sizes.

[0059] See Figure 7 In one specific embodiment, the main body 6 and at least part of the adjustment component 7 are respectively formed by a separate bottom cover a06 and a main component a07 detachably connected, and the air intake channel a03 is at least constructed on part of the bottom cover a06.

[0060] See Figure 2 and Figure 3 In one specific embodiment, the system further includes a plurality of selectively configurable filling members 8, which are used to fill at least partial gaps: the body 6 with at least partial gaps between the first adjusting member 71 and the second adjusting member 72, and the third adjusting member 73 with at least partial gaps between the first adjusting member 71 and the second adjusting member 72, respectively. The configured filling members 8 define a portion of the bearing surface a6 of the vacuum heat transfer mold a. These filling members 8 ensure that the vacuum heat transfer mold a can better support the object to be transferred, preventing negative pressure from directly adsorbing the object downwards through the gaps and causing surface depressions and deformation that would affect the transfer quality.

[0061] See Figure 3 The plurality of filling members 8 include a first filling member 81, a second filling member 82, and a third filling member 83. The first filling member 81 is used to fill at least a portion of the gap between the body 6 and the first adjusting member 71. The second filling member 82 is used to fill at least a portion of the gap between the body 6 and the second adjusting member 72. The third filling member 83 is used to fill at least a portion of the gap between the third adjusting member 73 and the first adjusting member 71 and the second adjusting member 72, respectively. The configured filling member 8, the second filling member 82, and the third filling member 83 define a portion of the bearing surface a6 of the vacuum heat transfer mold a.

[0062] See Figure 3 The first adjusting member 71 is constructed with a first support portion 91 that is retractably disposed on the body 6, the second adjusting member 72 is constructed with a second support portion 92 that is retractably disposed on the body 6, and the third adjusting member 73 is constructed with a third support portion 93 that is retractably disposed on the first adjusting member 71 and a fourth support portion 94 that is movably and retractably disposed on the second adjusting member 72.

[0063] The first filling member 81 is configured as a strip structure erected on the upper side of the first support 91;

[0064] The second filling member 82 is configured as a strip structure erected on the upper side of the second support 92;

[0065] The third filling member 83 is configured as an L-shaped structure composed of a first filling part 831 and a second filling part 832. The first filling part 831 is mounted on the upper side of the third support part 93, and the second filling part 832 is mounted on the upper side of the fourth support part 94.

[0066] See Figure 2 and Figure 3 The ends of the first filling member 81, the second filling member 82, and the third filling member 83 are bent downward to form flanges 90 that are engaged with the sides of the corresponding support portion 9. At least a portion of the flanges 90 defines at least a portion of the side surface of the vacuum heat transfer mold a. The support portion 9 facilitates the installation of the filling member 8, and the flanges 90 limit the position of the filling member 8.

[0067] The filling member 8 in this embodiment is not limited to the first to third filling members 83 described above. More filling members 8 of different sizes can be configured according to actual usage requirements, so that users can adjust the first lateral dimension y and / or the second lateral dimension x of the transfer mold according to actual needs. The following is a specific usage example:

[0068] See Figure 2 , Figure 3 and Figure 4 When it is necessary to increase the first lateral dimension y and the second lateral dimension x of the vacuum heat transfer mold a, the first adjusting component 71 and the third adjusting component 73 are moved away from the body 6 along the direction of the first lateral dimension y, exposing the first support portion 91 and the fourth support portion 94. The second adjusting component 72 and the third adjusting component 73 are moved away from the body 6 along the direction of the second lateral dimension x, exposing the second support portion 92 and the third support portion 93. The first filling component 81, the second filling component 82, and the third filling component 83 are respectively placed on the corresponding support portion 9. The body 6, the first adjusting component 71, the second adjusting component 72, the third adjusting portion, the first filling component 81, the second filling component 82, and the third filling component 83 together define at least a portion of the bearing surface a6 of the vacuum heat transfer mold a. The object to be transferred is placed on the vacuum heat transfer mold a, so that its surface is supported on the bearing surface a6 of the vacuum heat transfer mold a. In this embodiment, each adjusting component 7 moves away from the body 6 under the action of the elastic component a01.

[0069] Based on the vacuum heat transfer mold a in the above-described state, the following operations are performed:

[0070] When it is necessary to reduce the first lateral dimension y of the vacuum heat transfer mold a, the first adjusting component 71 is pushed towards the side closer to the body 6 along the direction of the first lateral dimension y, and the third adjusting component 73 is pushed towards the side closer to the second adjusting component 72, thereby reducing the gap between the first adjusting component 71 and the body 6, and the gap between the third adjusting component 73 and the second adjusting component 72. By replacing the first filling component 81 and the third filling component 83 with different specifications, the first lateral dimension y of the vacuum heat transfer mold a can be reduced. Alternatively, the first adjusting component 71 and the third adjusting component 73 can be further pushed to adjust the first lateral dimension y to the minimum. In this case, it is only necessary to replace the filling component 8 with a different specification to fill the gap between the second adjusting component 72 and the body 6, and the gap between the third adjusting component 73 and the first adjusting component 71. For example, when a mobile phone case is placed on the transfer mold, the mobile phone case pushes each adjusting component 7 to compress the elastic component a01, thereby adaptively adjusting the first lateral dimension y of the vacuum heat transfer mold a.

[0071] When it is necessary to reduce the second lateral dimension x of the vacuum heat transfer mold a, the second adjusting member 72 is pushed towards the side closer to the body 6 and the third adjusting member 73 is pushed towards the side closer to the first adjusting member 71 along the direction of the second lateral dimension x, thereby reducing the gap between the second adjusting member 72 and the body 6, and the gap between the third adjusting member 73 and the first adjusting member 71. By replacing the second filling member 82 and the third filling member 83 with different specifications, the second lateral dimension x of the vacuum heat transfer mold a can be reduced. Alternatively, the second adjusting member 72 and the third adjusting member 73 can be further pushed to adjust the second lateral dimension x to the minimum. In this case, it is only necessary to replace the filling member 8 with a different specification to fill the gap between the first adjusting member 71 and the body 6, and the gap between the third adjusting member 73 and the second adjusting member 72. For example, when a mobile phone case is placed on the transfer mold, the mobile phone case pushes each adjusting member 7 to compress the elastic member a01, thereby adaptively adjusting the second lateral dimension x of the vacuum heat transfer mold a.

[0072] See Figure 13 and Figure 14 As an alternative to the aforementioned plurality of filling members 8, the plurality of filling members 8 includes a fourth filling member 84 and a fifth filling member 85. The fourth filling member 84 is used to fill at least a portion of the gaps between the body 6 and the first adjusting member 71 and the second adjusting member 72, respectively. The fifth filling member 85 is used to fill at least a portion of the gaps between the third adjusting member 73 and the first adjusting member 71 and the second adjusting member 72, respectively. The configured fourth filling member 84 and fifth filling member 85 define a portion of the transfer mold bearing surface a6.

[0073] The fourth filling member 84 is configured as an L-shaped structure composed of a third filling part 841 and a fourth filling part 842. The third filling part 841 is mounted on the upper side of the first support part 91, and the fourth filling part 842 is mounted on the upper side of the second support part 92.

[0074] The fifth filling member 85 is configured as an L-shaped structure composed of a fifth filling part 851 and a sixth filling part 852. The fifth filling part 851 is mounted on the upper side of the third support part 93, and the sixth filling part 852 is mounted on the upper side of the fourth support part 94.

[0075] An avoidance structure 800 is provided between the fifth filling member 85 and the sixth filling member 86. In this embodiment, the avoidance structure 800 is configured as shown in the figure, with a first avoidance slope provided at the junction of the third filling part 841 and the fourth filling part 842 near the side of the sixth filling member 86, and a second avoidance slope corresponding to the first avoidance slope provided at the junction of the fifth filling part 851 and the sixth filling part 852 near the side of the fifth filling member 85, thereby avoiding interference between the fifth filling member 85 and the sixth filling member 86.

[0076] The ends of the fourth filling member 84 and the fifth filling member 85 are bent downward to form a flange 90 that is engaged with the side of the corresponding support portion 9. At least a portion of the flange 90 defines at least a portion of the side of the transfer mold. The flange 90 can limit the filling member 8.

[0077] The above replacement scheme uses two filler components 8, which effectively reduces the number of filler components 8 and facilitates installation and disassembly.

[0078] See Figure 15 and Figure 16 As an alternative to the aforementioned plurality of filling members 8, the plurality of filling members 8 include a sixth filling member 86, a seventh filling member 87, an eighth filling member 88, and a ninth filling member 89. The sixth filling member 86 is used to fill at least a portion of the gap between the body 6 and the first adjusting member 71, the seventh filling member 87 is used to fill at least a portion of the gap between the body 6 and the second adjusting member 72, the eighth filling member 88 is used to fill at least a portion of the gap between the first adjusting member 71 and the third adjusting member 73, and the ninth filling member 89 is used to fill at least a portion of the gap between the second adjusting member 72 and the third adjusting member 73.

[0079] The sixth filling member 86 is configured as a strip structure erected on the upper side of the first support 91;

[0080] The seventh filling member 87 is configured as a strip structure erected on the upper side of the second support 92;

[0081] The eighth filling member 88 is configured as a strip structure erected on the upper side of the third support 93;

[0082] The ninth filling member 89 is configured as a strip structure erected on the upper side of the fourth support 94.

[0083] The ends of the sixth filling member 86, the seventh filling member 87, the eighth filling member 88, and the ninth filling member 89 are bent downward to form flanges 90 that are engaged with the sides of the corresponding support portion 9. At least a portion of the flanges 90 defines at least a portion of the side of the transfer mold. The flanges 90 can limit the filling member 8.

[0084] The above replacement scheme uses four filling components 8. Although this arrangement increases the number of filling components 8, it effectively reduces the volume of each filling component 8, making it easier to store.

[0085] See Figure 5 and Figure 8 The body 6 has an internal structure with a first guide gap 511 extending along a first lateral dimension y and a second guide gap 512 extending along a second lateral dimension x. The first adjusting member 71 has an internal structure with a third guide gap 513 extending along a second lateral dimension x. The second adjusting member 72 has an internal structure with a fourth guide gap 514 extending along a first lateral dimension y. The first adjusting member 71 has a first guide portion 521 movably inserted into the first guide gap 511. The second adjusting member 72 has a second guide portion 522 movably inserted into the second guide gap 512. The third adjusting member 73 has a third guide portion 523 movably inserted into the third guide gap 513 and a fourth guide portion 524 movably inserted into the fourth guide gap 514.

[0086] See Figure 5 The main body 6 has a first limiting boss a04.1 internally, and a first guide gap 511 and a second guide gap 512 are formed between the corresponding side of the first limiting boss a04.1 and the inner side of the main body 6, respectively. The first adjusting component 71 has a second limiting boss a04.2 internally, and a third guide gap 513 is formed between the corresponding side of the second limiting boss a04.2 and the inner side of the first adjusting component 71. A fourth guide gap 514 is formed between the two opposite inner sides of the second adjusting component 72. The above arrangement allows the adjusting component 7 to move more smoothly.

[0087] See Figure 5Each guide portion 52 has an assembly space 502 on its inner side. A fixing protrusion 503, inserted into the assembly space 502, is constructed corresponding to the guide gap 51. An elastic member a01 is disposed within the assembly space 502, causing the corresponding adjusting component 7 to move in the direction that increases the lateral dimension of the vacuum heat transfer mold a. One end of the elastic member a01 is fixed relative to the fixing protrusion 503, and the other end abuts against the end of the assembly space 502 opposite to the fixing protrusion 503. This arrangement integrates the elastic member a01 with the guide portion 52, effectively utilizing the space between structures, making the structure more compact and occupying less space.

[0088] Compared with the prior art, this application improves the structure of the transfer mold by using an adjusting component 7, which is part of the transfer mold, to movably adjust at least one lateral dimension of the transfer mold. This allows the transfer mold to adapt to objects of different sizes, improving its versatility and reducing the cost to users for the transfer mold. Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this application should also fall within the protection scope of the claims of this application. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this application.
