[0047] The diaphragm required for IMD in-mold decoration injection molding technology needs to go through three processes during production: diaphragm printing, cutting and blanking, and molding. The molding process is completed on the molding device, and the flat diaphragm can be pressed into a three-dimensional structure through hot pressing of the upper and lower molds.

[0048] In the related art, a flat diaphragm can be pressed into a three-dimensional shape by hot pressing the upper and lower molds. However, when the diaphragm is subjected to hot pressing, the diaphragm will adhere to the upper and lower molds. It will adhere to the lower mold, making it inconvenient to remove. At the same time, it will adhere to the upper mold, causing the diaphragm to rise with the upper mold when the upper mold rises. During the rising process, the diaphragm will fall off and cause the diaphragm to be damaged.

[0049] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a diaphragm calendering forming device. When it is needed, only one group of first threaded rods 241 needs to be rotated to drive the other group of first threaded rods 241 to rotate through the bevel gear 23. The rotating first threaded rod 241 controls the support plate 243 and the L-shaped fixing plate 25 on the top of the support plate 243 to move toward one side of the lower mold 22 through the first threaded sleeve 242 to fix the diaphragm 14. At the same time, the second threaded rod 271 rotates through the bevel gear 23 to control the top plate 274 to descend and retract into the interior of the lower mold 22. When the first threaded rod 241 is rotated in the opposite direction to control the L-shaped fixing plate 25 to move toward the side away from the lower mold 22, the second threaded rod 271 rotates in the opposite direction through the bevel gear 23 to control the top plate 274 to rise and extend out of the interior of the lower mold 22, thereby pushing the diaphragm 14 away from the lower mold 22, making it convenient to take out the diaphragm 14.

[0050] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0051] Combination Figure 1-Figure 4 The embodiment of the present application provides a diaphragm calendering molding device, including a device body 1, the device body 1 includes: a diaphragm forming machine 12 is arranged on the outside of the workbench 11; an upper mold 13 is arranged on the diaphragm forming machine 12; a fixed component 2 is arranged on the top of the workbench 11; a diaphragm 14 is arranged on the fixed component 2; the fixed component 2 includes: a base 21 is arranged on the top of the workbench 11; a lower mold 22 is arranged on the base 21; a bevel gear 23 is arranged inside the lower mold 22; a moving component 24 is symmetrical on both sides of the bevel gear 23 and passes through the base 21 and the lower mold 22; an L-shaped fixed plate 25 is symmetrical on the top of the moving component 24; and a disengagement component 27 is arranged on the top of the bevel gear 23.

[0052] When in use, the diaphragm 14 is placed on the lower mold 22, and the L-shaped fixing plate 25 is controlled by the moving component 24 to move toward one side of the lower mold 22. When the L-shaped fixing plate 25 moves to the predetermined position, the diaphragm forming machine 12 is started through an external power supply. The diaphragm forming machine 12 heats the upper mold 13 and drives the upper mold 13 to move downward to press the diaphragm 14 on the lower mold 22 into shape. After pressing, the diaphragm forming machine 12 controls the rise. At this time, the L-shaped fixing plate 25 will fix the diaphragm 14 to prevent the diaphragm 14 from adhering to the upper mold, causing the diaphragm to rise with the upper mold when the upper mold rises. During the rising process, the diaphragm falls off, causing the diaphragm to be damaged. After the upper mold rises, the L-shaped fixing plate 25 is controlled by the moving component 24 to move toward the side away from the lower mold 22. At the same time, the diaphragm 14 will be separated from the lower mold 22 through the separation component 27 to prevent the diaphragm 14 from adhering to the lower mold, causing inconvenience in removal.

[0053] Specifically, the model of the film forming machine 12 is AS201F-G, and its working principle is that it is equipped with an upper mold and a lower mold, and uses the high pressure of gas to directly press the heated and softened sheet onto the lower mold to complete the formed parts. After the film material is heated to the softening point, the mold is closed, and the high-pressure air in the upper mold cavity is pressed from top to bottom through segmented high pressure, and the lower mold cavity is vacuumed, so that the film material and the mold are perfectly joined together. The principle structure is not drawn in the attached figure.

[0054] In some embodiments, the moving assembly 24 includes: a first threaded rod 241 symmetrical to both sides of the bevel gear 23, and passing through the lower mold 22 and the base 21; a first threaded sleeve 242, which is sleeved on the outer side of the first threaded rod 241, and a support plate 243 is arranged on the outer side of the first threaded sleeve 242 and fixedly connected to the L-shaped fixed plate 25. Rotating one group of first threaded rods 241 drives the other group of first threaded rods 241 to rotate through the bevel gear 23, and the rotating first threaded rods 241 control the left and right movement of the support plate 243 and the L-shaped fixed plate 25 on the top of the support plate 243 through the first threaded sleeve 242.

[0055] In some embodiments, a limiting plate 26 is provided on the outer side of the first threaded rod 241 to cooperate with the first threaded sleeve 242, which limits the first threaded sleeve 242 and prevents the first threaded sleeve 242 from moving too much toward one side of the lower mold 22, resulting in excessive pressure on the diaphragm 14 by the L-shaped fixing plates 25 on both sides of the diaphragm 14, causing damage to the diaphragm 14.

[0056] In some embodiments, the disengagement assembly 27 includes: a second threaded rod 271 is arranged on the top of the bevel gear 23 and is located inside the lower mold 22; a second threaded sleeve 272 is sleeved on the outside of the second threaded rod 271; an L-shaped support plate 273 is arranged on the outside of the second threaded sleeve 272 and passes through the top of the lower mold 22; a top plate 274 is arranged on the top of the L-shaped support plate 273, and the first threaded rod 241 rotates while the second threaded rod 271 is rotated through the bevel gear 23, and the rotating second threaded rod 271 controls the rise and fall of the L-shaped support plate 273 and the top plate 274 through the second threaded sleeve 272. By controlling the rise of the top plate 274, the diaphragm 14 is separated from the lower mold 22. When the first threaded rod 241 is rotated to control the L-shaped fixing plate 25 to move toward one side of the lower mold 22 to fix the diaphragm 14, the second threaded rod 271 rotates through the bevel gear 23 to control the top plate 274 to descend and retract into the interior of the lower mold 22. When the first threaded rod 241 is rotated in the opposite direction to control the L-shaped fixing plate 25 to move toward the side away from the lower mold 22, the second threaded rod 271 rotates in the opposite direction through the bevel gear 23 to control the top plate 274 to rise and extend out of the interior of the lower mold 22, thereby separating the diaphragm 14 from the lower mold 22, making it convenient to take out the diaphragm 14.

[0057] In some embodiments, a positioning rod 28 that cooperates with the diaphragm 14 is provided inside the base 21 and is located on the outside of the lower mold 22, so that when the diaphragm 14 is placed, the positioning rod 28 can accurately place the diaphragm 14 on the lower mold 22.

[0058] In some embodiments, a slider 211 is provided at the bottom of the base 21, and a positioning groove 212 matching the slider 211 is provided on the workbench 11, so that the base 21 is slidably connected to the workbench 11, which increases the convenience of disassembly and assembly of the base 21.

[0059] In some embodiments, a fixing bolt 213 that cooperates with the workbench 11 is disposed on the slider 211 and passes through the slider 211 , thereby increasing the stability of the fixed base 21 after the base 21 is installed.

[0060] In some embodiments, a connecting plate 131 is provided on the outer side of the upper mold 13 and is fixed to the diaphragm forming machine 12 by bolts. By disassembling and assembling the bolts on the connecting plate 131, the convenience of disassembling and assembling the upper mold 13 is increased.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0062] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
