Description

Technical Field

[0001] This utility model relates to the field of hot stamping equipment, specifically to hot stamping equipment for large-angle workpieces. Background Technology

[0002] Hot stamping on plastic surfaces is a common decorative technique widely used in the surface treatment of various electronic products. Traditional hot stamping typically uses a rigid metal template for transfer, and its application on flat or slightly curved surfaces is relatively mature. However, for plastic workpieces with large angles (>90°), especially structural components such as television stands with large angles of 120°-160°, there are significant technical limitations. To cover the entire curved surface, multiple segmented hot stamping operations are often required, resulting in defects such as overlapping seams or misalignment. For example, Chinese patent document CN217622705U discloses a plateless hot stamping device, which includes a hot press plate and a pressure plate, wherein the hot press plate is connected to a driving device. A substrate is placed between the hot press plate and the pressure plate, and a silicone plate is detachably connected to the side of the hot press plate closest to the substrate. An ink layer is placed on the side of the substrate closest to the electroplated aluminum layer. An electroplated aluminum layer is placed between the silicone plate and the ink layer. The silicone layer allows for hot stamping on curved or uneven surfaces. However, for plastic workpieces with large angles, especially structural parts with large angles of 120°-160° such as TV bases, the silicone mold for the planar structure of such large-angle bent structural parts cannot adapt to the deformation requirements of large-angle planes. This results in the hot stamping film not being able to fully adhere in the corner area, causing incomplete or missing transfers. Utility Model Content

[0003] The present invention aims to provide a hot stamping equipment for large-angle workpieces, so as to provide a device capable of performing integrated hot stamping on workpieces bent at large angles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a hot stamping equipment for large-angle workpieces, including a hot pressing substrate, the hot pressing substrate including a side pressure plate and a main pressure plate connected together in the left and right directions, the side pressure plate and the main pressure plate are at a set angle, the lower surface of the main pressure plate and the surface of the side pressure plate at the set angle to the main pressure plate are both working surfaces, a silicone layer is embedded in the middle of the front and back directions of the working surfaces of the side pressure plate and the main pressure plate, and a heating tube for heating the silicone layer is embedded in both the side pressure plate and the main pressure plate.

[0005] The beneficial effects of this solution are as follows: By setting an angle between the main pressure plate and the side pressure plate, and embedding a silicone layer on their surface, the silicone layer can tightly adhere to the surface of the workpiece bent at a large angle after being heated and softened, achieving one-time coverage of the entire large-angle turning area. This avoids the problems of overlapping seams or misalignment caused by multiple segmented hot stamping in traditional processes. Furthermore, heating tubes are embedded inside the main pressure plate and the side pressure plate to uniformly heat the silicone layer, ensuring that the silicone layer maintains good flexibility and adhesion at high temperatures. This guarantees the complete transfer of the hot stamping film in the corner area and improves the finished product quality of hot stamping on large-angle workpieces.

[0006] This technical solution has a simple structural design, is applicable to large-angle plastic workpieces such as TV stands, has strong process adaptability, and has good value for promotion and application.

[0007] Preferably, as an improvement, it also includes a hot stamping table, which is provided with a mounting fixture for mounting the workpiece to be processed. A lifting table is also fixed on one side of the hot stamping table. A mounting plate is slidably mounted on the lifting table. It also includes a lifting cylinder. A pressure plate is connected to the bottom of the mounting plate through the lifting cylinder. The hot pressing substrate is fixed on the lower surface of the pressure plate. The mounting fixture slides and engages with the upper surface of the hot stamping table and can be opposite to the hot pressing substrate.

[0008] The beneficial effects are as follows: by setting up a lifting platform and mounting plate, the pressure plate and hot pressing substrate can move up and down under the drive of the lifting cylinder, thereby realizing the rapid pressing and separation between the hot pressing substrate and the workpiece, ensuring the high efficiency of the one-time hot stamping process. The hot pressing substrate is fixed on the lower surface of the pressure plate, and under the action of the lifting cylinder, the hot pressing substrate can be driven to move up and down smoothly as a whole, avoiding the positional errors caused by traditional manual alignment or multi-stage pressing, and improving the adhesion and transfer integrity of the hot stamping film on the workpiece surface, especially in large-angle areas.

[0009] Preferably, as an improvement, the upper surface of the mounting fixture is provided with several horizontal slide rails, and the lower surface of the mounting fixture is provided with multiple sliders that slide in cooperation with the corresponding horizontal slide rails, so that the mounting fixture can move away from and towards the lifting platform via the horizontal slide rails.

[0010] The beneficial effects are as follows: The hot stamping table is equipped with a mounting fixture and adopts a sliding fit structure. The mounting fixture can move away from and towards the lifting table via a horizontal slide rail. The workpiece to be processed can be installed when it is away from the lifting table. After installation, the mounting fixture can be pushed back for hot stamping, avoiding burns to the workers' hands and improving the safety and ease of operation of the equipment.

[0011] Preferably, as an improvement, the thickness of the silicone layer is in the range of 0.35~0.45mm, and the material of the silicone layer is high-temperature resistant silicone.

[0012] The beneficial effects are as follows: the above thickness can ensure that the silicone layer has sufficient extensibility and adhesion after being heated, and can avoid uneven heat conduction caused by excessive thickness or insufficient strength caused by excessive thinness. The use of high temperature resistant silicone material can work for a long time in high temperature environment without aging, cracking or deformation, and ensure that the hot stamping film can be evenly pressed and completely transferred in the corner area.

[0013] Preferably, as an improvement, it also includes a PID temperature control module for controlling the temperature of the heating element, the PID temperature control module being electrically connected to the heating element.

[0014] The beneficial effects are as follows: By using the PID temperature control module to perform real-time temperature detection and closed-loop control of the heating tube, the temperature of the silicone layer during the heating process can be kept stable, avoiding insufficient softening or excessive aging of the silicone layer due to excessive temperature fluctuations. PID control can achieve rapid heating and constant temperature maintenance, improving the temperature uniformity when the hot stamping film is bonded to the workpiece surface, and ensuring the transfer quality.

[0015] Preferably, as an improvement, tensioning rollers for tensioning the hot stamping film are provided on both the front and rear sides of the pressure plate.

[0016] The beneficial effect is that by arranging tension rollers before and after the pressure plate, the hot stamping film can be kept taut during feeding and output, avoiding wrinkles, loosening or displacement of the hot stamping film.

[0017] Preferably, as an improvement, the silicone layer (3) protrudes 0.15~0.25mm from the working surface. Attached Figure Description

The lifting platform and mounting plate 6 allow the pressure plate 8 and the hot-pressing substrate 11 to move up and down under the drive of the lifting cylinder 7, thereby achieving rapid pressing and separation between the hot-pressing substrate 11 and the workpiece, ensuring the high efficiency of the one-time hot stamping process. The hot-pressing substrate 11, fixed to the lower surface of the pressure plate 8, can be smoothly raised and lowered by the lifting cylinder 7, avoiding positional errors caused by traditional manual alignment or multi-stage pressing, and improving the adhesion and transfer integrity of the hot stamping film on the workpiece surface, especially in large-angle areas.
