[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0029] As Figures 2 - 4 shown, in one embodiment, a clamping mechanism for preventing the rebound of the product sealing ring is used for fixing the product after hot melting in a hot melting machine group and is fixed on the workbench 1. It is characterized by including:

[0030] A product placement station for placing the hot-melted product;

[0031] A fixture station is arranged at the upper end of the product placement station and is used to apply a downward pressure to the hot-melted product for clamping and fixing. In use, the fixture station is the clamping unit of the clamping mechanism proposed in this embodiment. After the hot-melted product has been fixed on the product placement station, the product can be clamped by the clamping unit, and then hot melting is carried out. After the hot-melt head is reset, it still remains in the clamped state until the product is cooled and shaped, thereby effectively preventing the problem of seal failure caused by the rebound of the sealing ring and effectively improving the quality of the product.

[0032] Specifically, the product placement station is arranged on the product seat 2, and the product seat 2 is located between two slide rails 3. A pull rod 4 is arranged at one end of the product seat 2. After the product is cooled and shaped, the clamping unit is loosened, and when the pull rod 4 is pulled, the product seat 2 moves along the slide rails 3 to enter the next process for blanking.

[0033] Furthermore, the fixture station includes a pressing plate 5. There are two pressing plates 5, which are respectively arranged on both sides of the product placement station. A vertical movement connecting rod 6 is connected to the lower end of the pressing plate 5. The lower end of the vertical movement connecting rod 6 passes through the support plate 7 and is connected to a driving unit. The driving unit can drive the vertical movement connecting rod 6 to move downward, and then drive the pressing plate 5 to move downward to clamp the product during cooling and shaping, preventing the sealing ring from rebounding and causing seal failure.

[0034] In the embodiment of the present application, the driving unit includes a slider 8 that is movably connected to the vertical movement connecting rod 6. An arc-shaped groove 9 is formed in the slider 8. One end of the slider 8 is connected to a cylinder 10. When clamping, the cylinder 10 drives the slider 8 to move leftward. Since the left side height of the arc-shaped groove 9 is greater than the right side, when moving leftward, the lower end of the vertical movement connecting rod 6 slides and connects with the right end of the arc-shaped groove 9, causing the vertical movement connecting rod 6 to move downward and the pressing plate 5 to move downward to achieve clamping. In other preferred embodiments, the entire driving unit can also be a cylinder 10 or an electric cylinder directly driving the vertical movement connecting rod 6 to move up and down. It can be selected according to specific needs and space limitations.

[0035] Further, the pressing plate 5 and the up-and-down moving connecting rod 6 are detachably connected. In this embodiment, they are fixedly connected by bolts. When the pressing plate 5 is damaged or needs to be cleaned, only the pressing plate 5 needs to be removed and replaced or cleaned.

[0036] Reference Figure 1 , a hot melt mold including a clamping mechanism provided by the present application specifically includes a workbench 1, that is, the workbench 1 surface. A hot melt machine frame 11 is provided on the workbench 1 surface. The hot melt machine frame 11 serves as a support frame body, and various working unit modules can be provided above it. A hot melt module 12 is provided below the hot melt machine frame 11. The hot melt module 12 can move downward to perform hot melting on the product clamped by the clamping mechanism. Therefore, the hot melt module 12 needs to be arranged directly above the clamping mechanism.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
