Description

Technical Field

[0001] This utility model relates to the field of hot stamping equipment technology, and in particular to a hot stamping device for integrated molding of automobile air intake grilles. Background Technology

[0002] After the air intake grille is formed, it usually needs to be hot-stamped to print hot-stamping foil on its surface for a decorative purpose. Air intake grilles are typically long, and conventional hot-stamping equipment cannot accommodate a hot-stamping die head that fits the entire surface. Usually, only partial hot-stamping can be performed. During hot-stamping, only one side of the grille frame can be fixed to the fixture for hot-stamping, and then the other side of the frame needs to be manually changed and fixed to the fixture for hot-stamping again. This process needs to be repeated multiple times, resulting in low efficiency. Chinese patent document CN202320732176.0 discloses an air intake grille hot-stamping device. In this application, a linear displacement mechanism sends the workpiece to the hot-stamping station, a lifting drive mechanism drives it to press down to complete the hot-stamping of one side of the frame, and then the linear displacement mechanism sends the workpiece away from the hot-stamping station to a certain position. A rotary motor then drives the support plate to rotate and sends it back to the hot-stamping station to hot-stamp the other side of the frame. This hot stamping method is only suitable for flat grid frames. However, some grid frames are curved, and the hot stamping die head needs a specially designed inclined structure to fit the grid surface. Therefore, the method of using a single rotating grid cannot meet the automated hot stamping needs of most types of grid frames. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a hot stamping device for integrated molding of automotive air intake grilles, which solves the problem that existing automatic hot stamping devices cannot meet the hot stamping needs of most types of grille frames.

[0004] The specific technical solution is as follows:

[0005] A hot stamping device for integrated molding of automotive air intake grilles includes a base, on which a conveying mechanism and a hot stamping mechanism are mounted.

The lifting frame is housed within the mounting frame and is driven to rise and fall by a drive cylinder located at the top of the mounting frame. A flipping frame is located at the bottom of the lifting frame, with a hot stamping die at each of its upper and lower ends. The two ends of the flipping frame are rotatably mounted on the mounting frame via connecting shafts. The flipping drive device is mounted on the lifting frame and drives the flipping frame to rotate 180 degrees, enabling the switching of the hot stamping die.

[0007] Furthermore, the bottom center of the rotating support is connected to a rotating shaft, and the displacement seat is provided with a rotating seat adapted to the rotating shaft; the rotation drive device includes a rotary motor, a driving wheel, and a driven wheel. The rotary motor is located at the bottom of one side of the displacement seat, and the output shaft of the rotary motor passes through the displacement seat and is connected to the driving wheel. The driven wheel is located on the rotating shaft and is connected to the driving wheel via a transmission belt, so that the rotary motor drives the rotating support to rotate.

[0008] Furthermore, the tilting drive device includes a tilting motor, a second driving wheel, and a second driven wheel. The tilting motor is located on the top of the lifting frame, the second driving wheel is located on the output shaft of the tilting motor, and the second driven wheel is located on the connecting shaft at one end of the tilting frame. The second driven wheel is connected to the second driving wheel via a transmission belt, thereby enabling the tilting motor to drive the tilting frame to rotate.

[0009] Furthermore, each end of the mounting frame is provided with a set of mounting seats, and a roller is rotatably provided between each set of mounting seats. The roller is driven by a motor to rotate and realize the winding or unwinding of the hot stamping foil.

[0010] Furthermore, the flipping frame has a rectangular frame structure, and the hot stamping molds at the upper and lower ends of the flipping frame are symmetrically arranged.

[0011] The beneficial effects of this utility model are reflected in:

[0012] Compared with the prior art, this application uses a rotatable rotating support to drive the grid frame to rotate 180 degrees, realizing the switching of the two sides of the grid frame. It is combined with a hot stamping die head that can be flipped up and down to switch the die head, thereby realizing the hot stamping operation on both sides of the grid frame. It can be applied to the automated hot stamping needs of most types of grid frames. Attached Figure Description

[0018] Please see the appendix Figure 1-2This embodiment provides a hot stamping device for integrated molding of automotive air intake grilles, including a base 1. The base 1 is equipped with a conveying mechanism and a hot stamping mechanism. The hot stamping mechanism is located at one end of the conveying mechanism and includes a mounting frame 2, a lifting frame 3, a flipping drive device, and a hot stamping die head 6. The lifting frame 3 is located inside the mounting frame 2. The lifting frame 3 is driven to lift and lower by a drive cylinder 21 located at the top of the mounting frame 2. A flipping frame 4 is located at the bottom of the lifting frame 3. A hot stamping die head 6 is located at each of the upper and lower ends of the flipping frame. The flipping frame 4 has a rectangular frame structure, and the hot stamping dies head 6 at the upper and lower ends of the flipping frame 4 are symmetrically arranged. The two ends of the flipping frame 4 are rotatably mounted on the two ends of the mounting frame 2 through a connecting shaft 41. The flipping drive device is located on the lifting frame 3 and is connected to one of the connecting shafts 41 to drive the flipping frame 41 to rotate 80 degrees, thereby realizing the switching of the hot stamping die head 6.

[0019] The conveying mechanism includes a linear displacement component 7, a displacement seat 8, a rotary support 9, and a rotary drive device. One end of the linear displacement component 7 extends into the mounting frame 2. The displacement seat 8 is movably mounted on the linear displacement component 7, and the rotary support 9 is rotatably mounted on the displacement seat 8. The rotary drive device is mounted on the displacement seat 8 and drives the rotary support 9 to rotate 180 degrees. The rotary support 9 has symmetrically arranged positioning seats 11 at both ends for supporting the grid frame, so that the conveying mechanism can drive the grid frame to rotate and switch to the other side, and drive the displacement seat 8 to convey one side of the grid frame to the hot stamping station below the hot stamping die head 6, so that hot stamping can be performed.

[0020] In this embodiment, the linear displacement assembly 7 includes a guide rail 73, a lead screw 72, and a displacement motor 71. The guide rail 73 is mounted on the base 1, and a displacement seat 8 is slidably mounted on the guide rail 73 via a slider. The lead screw 72 is horizontally mounted between the guide rails 73. The lead screw 72 is threadedly connected to the threaded seat 82 at the bottom of the displacement seat 8. One end of the lead screw 72 is rotatably mounted on a rotating seat at one end of the base 1 via a bearing, and the other end of the lead screw 72 is driven to rotate by the displacement motor 71 mounted at one end of the base 1. This enables the displacement motor 71 to drive the displacement seat 8 to move linearly via the lead screw 72, thereby sending the rotating support 9 and one side of the grid frame into the mounting frame 2 and placing it at the lower end of the hot stamping die head 6.

[0021] In this embodiment, the bottom center of the rotating support 9 is connected by a rotating shaft, and the displacement seat 8 is provided with a rotating seat 83 adapted to the rotating shaft; the rotation drive device includes a rotary motor 10, a driving wheel 101 and a driven wheel 102. The rotary motor 10 is located at the bottom of one side of the displacement seat 8. The output axis of the rotary motor 10 passes through the displacement seat 8 and is connected to the driving wheel 101. The driven wheel 102 is located on the rotating shaft and is connected to the driving wheel 101 through a transmission belt, so that the rotary motor 10 drives the rotating support 9 to rotate.

[0022] In this embodiment, the bottom ends of the rotating support 9 are respectively provided with support plates 91. The bottom of the support plates 91 is flat, and the two ends of the displacement seat 8 are provided with support blocks 81 at the bottom of the support plates 91. The two sides of the support blocks 81 are inclined surfaces, and the top of the support blocks 81 is fitted to the bottom of the support plates 91, so that the two ends of the rotating support 9 can be supported after the rotating support 9 rotates, thereby ensuring that it can cope with the downward pressure of the hot stamping die head 6 during hot stamping.

[0023] In this embodiment, the flipping drive device includes a flipping motor 5, a second driving wheel 51, and a second driven wheel 52. The flipping motor 5 is located on the top of the lifting frame 3. The second driving wheel 51 is located on the output shaft of the flipping motor 5. The second driven wheel 52 is located on the connecting shaft 41 at one end of the flipping frame 4. The second driven wheel 52 is connected to the second driving wheel 51 via a transmission belt, so that the flipping motor 5 drives the flipping frame 4 to rotate.

[0024] In this embodiment, a set of mounting seats 12 are provided at both ends of the mounting frame 2. A roller 121 is rotatably provided between each set of mounting seats 12. A hot stamping foil is sleeved on the roller 121. The roller 121 is driven to rotate by a motor at one end to realize the winding or unwinding of the hot stamping foil, so as to cooperate with the hot stamping die head 6 to perform hot stamping operation.

[0025] The working principle of this utility model is as follows: The linear displacement component 7 drives the displacement seat 8 to move towards the hot stamping mechanism, so that one side of the grid frame is moved into the mounting frame 2. Then, the drive cylinder 21 drives the lifting frame 3 to descend, and the hot stamping die head 6 at the bottom of the flipping frame 4 descends and cooperates with the hot stamping foil to hot stamp one side of the grid frame. After the hot stamping is completed, the displacement seat 8 is reset. Then, the rotary motor 10 drives the rotary support 9 to rotate 180 degrees. Then, the linear displacement component 7 drives the other side of the grid frame to move into the mounting frame 2. At the same time, the flipping motor 5 drives the flipping frame 4 to rotate 180 degrees, so that another hot stamping die head 6 moves to the hot stamping station. Then, the drive cylinder 21 drives the hot stamping die head 6 to hot stamp the other side of the grid frame, thereby realizing the automated hot stamping of both sides of the grid frame.
