Detailed Implementation

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This utility model provides a powder metallurgy dry pressing mold, including: a connecting base plate 1 and a splitting component 2; The top of the connecting base plate 1 is provided with a split assembly 2, which includes the following components: Positioning support frame 201: Located on the top of the connecting base plate 1, the positioning support frame 201 has extension protrusions 2011 fixedly connected on both sides, and a limiting slide rod 2012 fixedly connected between the extension protrusions 2011. The top of the limiting slide rod 2012 is provided with a bidirectional screw rod 2013, and one end of the bidirectional screw rod 2013 is fixedly connected to a first rotating handle 2014. Guide sleeve 202: Located on the outside of the limiting slide rod 2012, the guide sleeve 202 has a guide hole 2021 at the midpoint, a moving ring 2022 is fixedly connected to the top of the guide sleeve 202, a first screw hole 2023 is opened at the midpoint of the moving ring 2022, and a locking plate 2024 is fixedly connected to the top of the moving ring 2022. Lower mold 203: Located inside the positioning support frame 201, the lower mold 203 has fixed protrusions 2031 at both ends, and connecting base blocks 2032 at both ends of the bottom of the fixed protrusions 2031. The connecting base blocks 2032 have locking slots 2033, and locking inserts 2024 are fitted into the locking slots 2033.

[0021] During installation, the lower mold 203 is placed inside the positioning support frame 201. Then, the first rotating handle 2014 is rotated to drive the bidirectional lead screw 2013 to rotate. The bidirectional lead screw 2013 engages with the first screw hole 2023 on the moving ring 2022. The moving ring 2022 is guided to the upper limit of the limiting slide rod 2012 by the guide sleeve 202, so that the bidirectional lead screw 2013 drives the moving ring 2022 to move in the opposite direction. Thus, the moving ring 2022 drives the locking plate 2024 to be inserted into the locking slot 2033, thereby completing the installation of the lower mold 203. When replacing, simply rotate the first rotating handle 2014 in the opposite direction to drive the moving ring 2022 to move in the opposite direction through the bidirectional lead screw 2013. The moving ring 2022 then drives the locking plate 2024 to disengage from the locking slot 2033, and then the lower mold 203 can be removed and replaced with a lower mold 203 of different specifications for manufacturing.

[0022] Example 2: Based on Example 1, wherein, as Figure 4 and Figure 5 As shown, the top of the connecting base plate 1 is provided with a stamping assembly 3. The stamping assembly 3 includes a fixed vertical plate 301, a reinforcing angle plate 3011 and an assembly top plate 3012. The fixed vertical plates 301 are fixedly connected to both ends of the top of the connecting base plate 1. The reinforcing angle plate 3011 is fixedly connected between the fixed vertical plate 301 and the connecting base plate 1. The assembly top plate 3012 is fixedly connected between the tops of the fixed vertical plates 301.

[0023] A linkage cylinder 302 is fixedly installed on the top of the assembly top plate 3012. The drive end of the linkage cylinder 302 is fixedly connected to the upper mold 3021. Guide protrusions 3022 are fixedly connected to both sides of the upper mold 3021. A guide groove 3023 is opened in the middle of the fixed vertical plate 301. The guide protrusions 3022 are slidably installed in the guide groove 3023.

[0024] The upper mold 3021 is provided with an adjustment component 4, which includes an adjustment groove 401, a pressure block 4011, a rotating shaft groove 4012, and a bearing 4013. The upper mold 3021 has an adjustment groove 401 inside, and a pressure block 4011 is provided in the adjustment groove 401. The top of the pressure block 4011 has a rotating shaft groove 4012, and a bearing 4013 is fixedly installed inside the rotating shaft groove 4012.

[0025] A guide rod 402 is fixedly connected to the top of the pressure block 4011, and a guide sliding hole 4021 is provided on the upper mold 3021. The guide rod 402 is slidably installed in the guide sliding hole 4021.

[0026] The top of the upper mold 3021 is provided with a second screw hole 403, in which a screw 4031 is engaged and installed. One end of the bottom of the screw 4031 is fixedly connected to the inner shaft of the bearing 4013, and the top of the screw 4031 is fixedly connected to a second rotating handle 4032.

[0027] By rotating the second handle 4032, the screw 4031 is driven to engage and move in the second screw hole 403. Under the guidance of the guide rod 402, the height of the pressing block 4011 protruding in the adjustment groove 401 can be adjusted to adapt to the use of lower molds 203 of different specifications and depths. By activating the linkage cylinder 302, the upper mold 3021 is pushed to move. The upper mold 3021 then drives the pressing block 4011 to cooperate with the lower mold 203 to press the powder. Through the cooperation of the guide protrusion 3022 and the guide slide 3023, the accuracy of the upper mold 3021 during movement is ensured, and deviation is prevented.

[0028] The specific usage and function of this embodiment are as follows: In this invention, during installation, the lower mold 203 is placed inside the positioning support frame 201, and then the first rotating handle 2014 is rotated to drive the bidirectional lead screw 2013 to rotate. The bidirectional lead screw 2013 engages with the first screw hole 2023 on the moving ring 2022. However, the moving ring 2022 is guided to the upper limit by the guide sleeve 202 at the limit slide rod 2012, causing the bidirectional lead screw 2013 to drive the moving ring 2022 to move in the opposite direction. Thus, the moving ring 2022 drives the locking plate 2024 to be inserted into the locking slot 2033, thereby completing the installation of the lower mold 203. During replacement, simply rotate the first rotating handle 2014 in the opposite direction to drive the moving ring 2022 through the bidirectional lead screw 2013. Moving in opposite directions, the moving ring 2022 causes the locking plate 2024 to disengage from the locking slot 2033, allowing the lower mold 203 to be removed and replaced with a lower mold 203 of different specifications for production. Through the convenient disassembly method, when it is necessary to change the mold of different specifications, the operator does not need to use any external tools and can quickly complete the change with simple operation, which greatly reduces the complexity of operation, significantly improves the mold change speed, and further accelerates the overall production efficiency of the product and effectively shortens the production cycle. By starting the linkage cylinder 302, the upper mold 3021 is pushed to move, and the upper mold 3021 drives the pressing block 4011 to cooperate with the lower mold 203 to press the powder.
