This mold uses an adjusting mechanism to move multiple support blocks, allowing for adjustment of the support area and adaptability to various transfer housings. However, gaps exist between the support blocks. During the heat transfer process, the transfer housing needs to be heated, which softens the housing, potentially leaving marks on the transfer housing at these gaps. Utility Model Content

[0051] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0052] Reference Figure 1-6 This utility model proposes a universal heat transfer mold 22, which includes a support block, an adjustment mechanism 225 and a cover plate 227; multiple support blocks are provided; the adjustment mechanism 225 is connected to the support block in a transmission manner; the cover plate 227 is provided above the support block and is used to cover the gap between the support blocks.

[0053] Specifically, the adjustment mechanism 225 moves the support block to adjust the outer contour of the universal heat transfer mold 22 and adjust the support area to adapt to various transfer shells. At the same time, the cover plate 227 covers the gaps between the support blocks to solve the problem that the gaps of the universal heat transfer mold 22 may leave marks on the transfer shell during the heat transfer process.

[0054] Furthermore, in some embodiments, the plurality of support blocks include a left front support block 222, a left rear support block 224, a right front support block 221, and a right rear support block 223; the adjusting mechanism 225 is connected to the left front support block 222, the left rear support block 224, the right front support block 221, and the right rear support block 223 so that the left front support block 222, the left rear support block 224, the right front support block 221, and the right rear support block 223 can move in the front-back and left-right directions.

[0055] Specifically, the adjustment mechanism 225 is connected to the left front support block 222, the left rear support block 224, the right front support block 221, and the right rear support block 223, so that the left front support block 222, the left rear support block 224, the right front support block 221, and the right rear support block 223 can move in the front-back and left-right directions, thereby changing the external contour of the universal heat transfer mold 22. The universal heat transfer mold 22 can be adjusted according to the product. The universal heat transfer mold 22 is suitable for a variety of products and solves the problem that during the heat transfer process, there is a chance that the gaps of the universal heat transfer mold 22 will leave marks on the transfer shell.

[0056] Further, in some embodiments, the adjusting mechanism 225 includes a central seat 2251, left and right lead screws 2253, front and rear lead screws 2252, a left slider 2257, a left slider 2256, a front slider 2254, and a rear slider 2255; the middle part of the left and right lead screws 2253 is rotatably connected to the central seat 2251, and the left and right sections of the left and right lead screws 2253 have opposite helical directions; the left slider 2257 is threadedly slidably connected to the left section of the left and right lead screws 2253, and the left slider 2257 is slidably connected to the left front support block 222 and the left rear support block 224 in the left and right directions, respectively; the left slider 2256 is threadedly slidably connected to the right section of the left and right lead screws 2253, and the left slider 2256 is slidably connected to the right front support block 221 and the right rear support block 223 in the left and right directions, respectively; the middle part of the front and rear lead screws 2252 is rotatably connected to the central seat 2251. The front and rear sections of the lead screws 2252 have opposite helical directions; the front slider 2254 is threadedly slidably connected to the front section of the lead screws 2252, and the front slider 2254 is slidably connected to the left front support block 222 and the right front support block 221 in the front-rear direction respectively; the rear slider 2255 is threadedly slidably connected to the rear section of the lead screws 2252, and the rear slider 2255 is slidably connected to the left rear support block 224 and the right rear support block 223 in the front-rear direction respectively; the heat transfer universal mold 22 is provided with limiting members 226 in the front, rear, left and right directions respectively, and the limiting members 226 are located at adjacent support blocks among the left front support block 222, the left rear support block 224, the right front support block 221, and the right rear support block 223; the limiting members 226 are provided with limiting holes 2261, and the support blocks are provided with limiting posts, which are movably inserted into the limiting holes 2261.

[0057] Specifically, the universal heat transfer mold 22 is fixed on the heat transfer machine by the central seat 2251. By rotating the left and right lead screws 2253, the left sliders 2257 and 2256 move closer or further apart. This causes the left front support block 222 and the left rear support block 224 to move left and right along the axis of the left and right lead screws 2253, while the left slider 2256 causes the right front support block 221 and the right rear support block 223 to move left and right along the axis of the left and right lead screws 2253. Similarly, by rotating the front and rear lead screws 2252, the front slider 2254 and the rear slider 2255 move closer or further apart. This causes the left front support block 222 and the right front support block 221 to move left and right along the axis of the front and rear lead screws. The 2252 axis moves back and forth, and at the same time, the rear slider 2255 drives the left rear support block 224 and the right rear support block 223 to move back and forth along the front and rear lead screws 2252, thereby adjusting the size of the outer contour of the heat transfer universal mold 22, making the heat transfer universal mold 22 suitable for a variety of products; the limiting member 226 can limit the separation distance between two adjacent support blocks among the left front support block 222, left rear support block 224, right front support block 221 and right rear support block 223, and prevent the heat transfer universal mold 22 from falling apart due to excessive rotation; each support block is provided with a limiting post, and each limiting post is provided with a limiting hole 2261. The limiting hole 2261 and the limiting post cooperate to limit the maximum and minimum distance between two adjacent support blocks.

[0058] Furthermore, in some embodiments, the cover 227 includes a first gasket 2271 and a second gasket 2272; the first gasket 2271 and the second gasket 2272 are respectively disposed on two support blocks diagonally opposite each other, namely the left front support block 222, the left rear support block 224, the right front support block 221, and the right rear support block 223.

[0059] Specifically, in some embodiments, the first gasket 2271 and the second gasket 2272 are respectively disposed on the left front support block 222 and the right rear support block 223; in some embodiments, the first gasket 2271 and the second gasket 2272 are respectively disposed on the left rear support block 224 and the right front support block 221; each of the first gasket 2271 and the second gasket 2272 is larger than the left front support block 222, the left rear support block 224, the right front support block 221, and the right rear support block 223, and is located on the left front support block. When block 222, left rear support block 224, right front support block 221, and right rear support block 223 are close together, the overlapping area of ​​the first gasket 2271 and the second gasket 2272 is relatively large; when the left front support block 222, left rear support block 224, right front support block 221, and right rear support block 223 are far apart from each other, the overlapping area of ​​the first gasket 2271 and the second gasket 2272 becomes relatively small; the first gasket 2271 and the second gasket 2272 are always able to cover the gaps of the fixed support blocks.

[0060] Furthermore, in some embodiments, the thickness of the first gasket 2271 and the second gasket 2272 is less than or equal to 0.5 mm, and / or the softening temperature of the first gasket 2271 and the second gasket 2272 is higher than the softening temperature of the transfer housing.

[0061] Specifically, the thickness of the first gasket 2271 and the second gasket 2272 is less than or equal to 0.5 mm. The thickness of the first gasket 2271 and the second gasket 2272 is very thin, and they will basically not form wrinkles on the transfer housing. The softening temperature of the first gasket 2271 and the second gasket 2272 is higher than that of the transfer housing. That is, when the transfer housing is heated and softened for transfer, the first gasket 2271 and the second gasket 2272 are still hard, so that the first gasket 2271 and the second gasket 2272 can properly cover the gaps at the working temperature, thus solving the problem that there is a chance of leaving marks on the transfer housing at the gaps of the universal heat transfer mold 22 during the heat transfer process.

[0062] This application also proposes a heat transfer printing machine for a housing, including an upper cover 1 and a heating lower base 2; the upper cover 1 is provided with a first sealing ring 11; the heating lower base 2 includes a fixed base 21, a heating structure 24, a vacuuming mechanism 25 and the aforementioned universal heat transfer mold 22, the fixed base 21 is provided with a mounting groove 211, the universal heat transfer mold 22 is disposed in the mounting groove 211, and the universal heat transfer mold 22 is used to fix the heat transfer housing; the upper cover 1 covers the mounting groove 211 of the heating base, the fixed base 21 is provided with a second sealing ring that matches the first sealing ring 11, the second sealing ring is arranged around the periphery of the mounting groove 211; the vacuuming mechanism 25 is connected to the mounting groove 211.

[0063] Specifically, the universal heat transfer mold 22 is used to fix the transfer housing. When the upper cover 1 closes the mounting groove 211, the first sealing ring 11 and the second sealing ring clamp the heat transfer film and form a sealed space, and press the heat transfer film downward to make the heat transfer film adhere to the transfer housing. The heating structure 24 is used to heat the transfer housing. In some embodiments, the heat transfer mold 22 can be heated to heat the transfer housing. In some embodiments, the fixing seat 21 can be heated to heat the transfer housing. The vacuum mechanism 25 can create a negative pressure on the heat transfer film by vacuuming. The pressure sensor monitors and adjusts the pressure in real time to create a KPA constant pressure on the heat transfer film, so that the heat transfer film and the transfer housing are tightly attached. After the set time is reached, the pattern on the heat transfer film is transferred to the transfer housing.

[0064] In some embodiments, the vacuuming mechanism 25 includes a plurality of vacuum pumps, one of which is connected to the mounting slot 211.

[0066] Specifically, the pressing part 111 includes two sealing plates, which are located on both sides of the adsorption tank 212, making it convenient for the pressing part 111 to cover the adsorption tank 212; a vacuum pump of the vacuum mechanism 25 is connected to the adsorption tank 212, and a negative pressure can be achieved by vacuuming so that the upper cover 1 can stably cover the heated lower base 2, and can also achieve a certain sealing effect. Different vacuum pumps are responsible for different vacuuming tasks, which makes it convenient to control and achieve their respective functions; the second sealing ring 23 corresponds to the pressing part 111, which not only fixes the heat transfer film, but also forms a sealed cavity.

[0067] Furthermore, in some embodiments, the upper cover 1 and the heated lower base 2 are connected by a rotating connection device.

[0068] Specifically, the top cover 1 can be opened to the side, making it easy to insert the transfer shell and heat transfer film for heat transfer.

[0069] It should be noted that in some embodiments, the upper cover 1 can be slidably connected to the sliding guide post, so that the upper cover 1 can move up and down, which can facilitate the placement of the transfer shell and the heat transfer film for heat transfer; in some embodiments, the upper cover 1 is provided with a handle to facilitate lifting the upper cover 1.

[0070] Furthermore, in some embodiments, the heating base 2 is equipped with a pneumatic pump, which is connected to the upper cover 1. The upper cover 1 is provided with an air outlet located inside the lower pressure part 111.

[0071] Specifically, the heat transfer film contacts the first sealing ring, forming a sealing cavity at the upper cover 1. Pressure can also be applied to the heat transfer film using an air pump. In some embodiments, a pressure sensor is mounted on the universal heat transfer mold 22, and pressure can be applied via a vacuum mechanism 25.

[0072] Furthermore, the heating structure 24 includes a heating element, a heating control circuit, and a temperature sensor; the heating element is electrically connected to the heating control circuit; the temperature sensor is communicatively connected to the heating control circuit; the temperature sensor is used to detect the temperature inside the placement tank 211.

[0073] Specifically, the heating element is heated by the heating control circuit, which in turn heats the heat transfer film and the transfer housing. The temperature sensor is used to detect the temperature in the mounting tank 211 and feed the detection data back to the control circuit, so that the temperature can be adjusted in real time to keep the temperature stable during the heat transfer process.

[0074] This utility model proposes a universal heat transfer mold 22 and a heat transfer machine for housings. The adjustment mechanism 225 drives the support block to move and adjust the external contour of the universal heat transfer mold 22 and adjust the support area to adapt to various transfer housings. At the same time, the cover plate 227 covers the gaps between the support blocks, solving the problem that during the heat transfer process, the gaps of the universal heat transfer mold 22 may leave marks on the transfer housing.
