[0036] Example

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment provides a hot pressing fixture, including a bottom mold 10, a top mold 40, a first hot pressing block 20, and a second hot pressing block 30. The bottom mold 10 is provided with a stepped support part 101, a square rod 102 for supporting the workpiece inside, and a positioning block 103 for positioning the workpiece. The first hot pressing block 20 is laterally clamped or separated from the stepped support part 101. The second hot pressing block 30 is slidably disposed toward the positioning block 103. The top mold 40 is provided with at least one first abutment block 401 for pushing the first hot pressing block 20 to clamp with the stepped support part 101, and a second abutment block 402 for pushing the second hot pressing block 30 to clamp with the positioning block 103.

[0038] Specifically, the first hot pressing block 20 and the stepped support part 101 can be slidably connected through multiple guide rods (the workpiece being hot-pressed has through holes or notches to avoid the guide rods), ensuring smooth lateral movement of the first hot pressing block 20; at the same time, it is clamped and fixed with the stepped support part 101 for hot pressing. The square rod 102 can be inserted into the hollow hole of the workpiece to provide stable support and prevent deformation during hot pressing. Furthermore, the square rod 102 can cooperate with the stepped support part 101 to clamp the workpiece, enhancing its stability.

[0039] Furthermore, a positioning block 103 is located in the middle of the bottom mold 10, which can also cooperate with the second hot pressing block 30 for clamping. It can work in conjunction with the first hot pressing block 20 to achieve a multi-point clamping and fixing effect, thereby improving the accuracy and stability of hot pressing. At the same time, hot pressing can be performed on different surfaces of the workpiece to perform the required hot pressing operations.

[0040] In this embodiment, the angle formed between the moving direction of the second hot pressing block 30 and the moving direction of the first hot pressing block 20 is a right angle, thus forming two clamping and fixing in different directions, so that the workpiece is subjected to uniform force during the hot pressing process, avoiding deformation caused by force in one direction.

[0041] like Figure 3 As shown, in this embodiment, the clamping surface of the stepped support 101 is provided with a first limiting groove 1011 for fitting and placing the workpiece. The groove structure can limit the placement of the workpiece, and together with the first hot pressing block 20 clamping from the side, a stable support system is formed to ensure that the workpiece does not shift during the hot pressing process.

[0042] Furthermore, such as Figure 3As shown, in this embodiment, the top surface of the positioning block 103 is provided with a second limiting groove 1031, and the top mold 40 is provided with a clamping block 403 that cooperates with the positioning block 103 for clamping. Similarly, the second limiting groove 1031 can place another part of the workpiece, and then the clamping block 403 on the top mold 40 clamps it vertically, while the second hot pressing block 30 clamps it from the side, forming a three-dimensional fixation, ensuring that the workpiece remains stable under multi-directional force, avoiding any deformation, and improving the accuracy and quality of the hot-pressed product.

[0043] like Figure 2 and Figure 4 As shown, in this embodiment, the mating surface between the first abutment block 401 and the first hot pressing block 20 is the first abutment inclined surface 4011, which pushes the first hot pressing block 20 to move laterally. The mating surface between the second abutment block 402 and the second hot pressing block 30 is the second abutment inclined surface 4012, which pushes the second hot pressing block 30 to move laterally. Through the engagement of the inclined surfaces, the abutment force generated by the bottom mold 10 and the top mold 40 during mold closing can be switched to push the first hot pressing block 20 to move and the stepped support part 101 to clamp it, while simultaneously pushing the second hot pressing block 30 to clamp it with the positioning block 103, forming a synchronous driving effect and achieving the purpose of inclined pushing.

[0044] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the bottom mold 10 is provided with a sliding block 104 that abuts and fixes the square rod 102 to the stepped support 101. The top mold 40 is provided with a third abutting block 1041 that pushes the sliding block 104 to move. Alternatively, an inclined abutting method can be used, where the third abutting block 1041 drives the sliding block 104 to move and clamp, thus achieving the effect of abutting and clamping the workpiece between the square rod 102 and the stepped support 101. A return spring 1042 can also be installed between the sliding block 104 and the bottom mold 10 to give the sliding block 104 an initial force for reset, so that the workpiece can be removed later.

[0045] like Figure 3 As shown, in this embodiment, a plurality of first positioning pins 1012 are provided on the stepped surface of the stepped support 101. The positioning pins cooperate with the positioning blocks 103 on the workpiece to ensure that the workpiece is accurately positioned so that the workpiece always maintains the correct position during the hot pressing process, avoids processing errors caused by displacement, and further improves the quality of the finished product.

[0046] Furthermore, such as Figure 3 and Figure 4As shown, in this embodiment, a plurality of second positioning pins 1032 are provided on the top surface of the positioning block 103. Similarly, positioning holes on another part of the workpiece can be used for positioning and installation. By cooperating with the positioning holes, the second positioning pins 1032 ensure that the workpiece remains accurately positioned even when fixed at multiple angles, forming a comprehensive and stable system. It can also be used in conjunction with the positioning of the first positioning pin 1012 to form a multi-point fixing effect on the workpiece.

[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
