The driving component is connected to the upper mold component and is used to drive the upper mold component to move. The lower mold component is arranged corresponding to the upper mold component. The upper mold component is used to press and shape the product placed on the lower mold component. The upper mold component includes: a mounting plate component, a pre-pressing plate component, two side pressure plates, a central main pressure head, two side pressure heads, a central pressure-holding component, and a side pressure-holding component. The mounting plate component is connected to the upper mold component to drive the upper mold component to move. The drive assembly is connected to the pre-pressure plate assembly, which is installed on the mounting plate assembly via several limiting posts. The intermediate pressure holding assembly is installed on the pre-pressure plate assembly, and the intermediate main pressure head is installed on the mounting plate assembly. The two side pressure heads are each connected to the pre-pressure plate assembly via a slider rail assembly. The intermediate main pressure head is used to push the two side pressure heads. The two side pressure heads are respectively fixed to the corresponding side pressure plates. The side pressure plates are connected to the pre-pressure plate assembly via several limiting posts, and each side pressure plate is provided with a side pressure holding assembly.

[0006] Furthermore, the driving assembly includes a driving cylinder, the output end of which is connected to the upper mold assembly.

[0007] The beneficial effects of this utility model by adopting the above solution are as follows: the product is pressure-held and shaped by the product pressure-holding fixture, ensuring good quality and effectively guaranteeing the shape, size and position of the product after shaping. Compared with conventional cooling and shaping methods, the yield is increased by more than 95%; the pressure-holding and shaping speed is fast, effectively increasing production capacity; the equipment is simple and easy to operate.

[0011] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] Please refer to the following: Figures 1 to 3 In this embodiment, the present invention provides a product pressure-holding fixture, including: a drive assembly 1, an upper mold assembly 2, and a lower mold assembly 3. The drive assembly 1 is connected to the upper mold assembly 2 and is used to drive the upper mold assembly 2 to move. The lower mold assembly 3 is disposed corresponding to the upper mold assembly 2, and the lower mold assembly 3 has a matching receiving groove for the product. The upper mold assembly 2 is used to press and shape the product placed on the lower mold assembly 3. The upper mold assembly 2 includes: a mounting plate assembly 2, a pre-pressing plate assembly 22, two side pressure plates 23, a central main pressure head 24, two side pressure heads 25, a central pressure-holding assembly 26, and a side pressure-holding assembly 27. The central pressure-holding assembly and the side pressure-holding assembly each have a matching pressure-holding structure corresponding to the shape of the product. The mounting plate assembly 21 is connected to the drive assembly 1 and can move up and down under the drive of the drive assembly 1. The pre-pressure plate assembly 22 is installed on the mounting plate assembly 22 via several limiting posts. The pressing force can be adjusted and controlled by the springs of the limiting posts. The intermediate pressure holding assembly 26 is installed on the pre-pressure plate assembly 22. The intermediate main pressure head 24 is installed on the mounting plate assembly 21. The two side pressure heads 25 are connected to the pre-pressure plate assembly 25 via slider and slide rail assemblies. The slider and slide rail assemblies can limit and guide the movement trajectory of the pressure measuring head 25 when the intermediate main pressure head 24 pushes the two side pressure heads 25, ensuring the correct pressing position. The intermediate main pressure head 24 is used to push the two side pressure heads 25. The two side pressure heads 25 are fixed to the corresponding side pressure plates 23. The side pressure plates 23 are connected to the pre-pressure plate assembly 22 via several limiting posts. Each side pressure plate 23 is provided with a side pressure holding assembly 27.

[0013] Furthermore, the drive assembly 1 includes a drive cylinder, and the output end of the drive cylinder 1 is connected to the upper mold assembly 2.

[0014] Please continue to refer to the following: Figures 1 to 3When the pressure-holding fixture in this solution is working, the product is placed on the lower mold assembly 3, and the drive assembly 1 drives the upper mold assembly 2 to move downward. The middle main pressure head 24 located on the pre-pressure plate assembly 22 will first contact the product and press it. Subsequently, the drive assembly 1 continues to work, and the middle main pressure head 24 moves downward, thereby pushing the two side pressure heads 25 to move, so that the side pressure-holding assembly 27 located on the side pressure plate 23 also contacts the product and presses it, thereby achieving pressure holding and shaping of the product.

[0015] In summary, this solution uses a pressure-holding fixture to shape and maintain the product, ensuring good quality and effectively guaranteeing the shape, size, and position of the product after shaping. Compared with conventional cooling and shaping methods, the yield rate is increased by more than 95%. The pressure-holding and shaping speed is fast, effectively increasing production capacity. The equipment is simple and easy to operate.

[0016] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
