[0027] Please refer to Figures 1-5 , the present utility model provides the following technical solutions:

[0028] A multi-mode cavity core pressing machine includes a workbench 1, two support plates 10, a storage box 6, and a first electric telescopic rod 7. A plugging mechanism 8 is provided at the bottom of the workbench 1, a multi-mode cavity pressing mechanism 9 is provided at the top of the workbench 1, and a storage box 3 is provided at the bottom of the workbench 1;

[0029] The plugging mechanism 8 includes a plugging plate 801, four dense-hole filtering exhaust ports 802, and a second electric telescopic rod 803. The dense-hole filtering exhaust ports 802 are opened inside the plugging plate 801, and the front side of the telescopic end of the second electric telescopic rod 803 is fixedly connected to the rear side of the plugging plate 801.

[0030] In this embodiment: When the core pressing rod 5 moves into the processing tube 902 to press the powder material into shape, the excess air inside the processing tube 902 will be filtered through the dense-hole filtering exhaust ports 802 and then discharged from the processing tube 902, improving the density and quality of the core material after pressing into shape, and avoiding the problem that in the prior art solution, after the plugging cover plugs the bottom of the processing tube, when the core pressing rod moves into the processing tube for downward pressing, the air inside the processing tube is not convenient to be discharged, affecting the quality of the core body after the lead core powder is pressed into shape.

[0031] Specifically, as Figure 4 shown, the multi-mode cavity pressing mechanism 9 includes four connecting rings 901, four processing tubes 902, and a multi-pass tube 903. The connecting rings 901 are fixedly sleeved on the surface of the processing tubes 902, and the front side of the multi-pass tube 903 is fixedly connected and communicated with the rear side of the connecting rings 901.

[0032] Specifically, as Figure 1 and Figure 2 shown, the bottom of the processing tube 902 passes through the workbench 1 and extends to the bottom of the workbench 1. The bottom of the processing tube 902 contacts the top of the plugging plate 801, and the processing tube 902 is connected and communicated with the dense-hole filtering exhaust ports 802.

[0033] Specifically, as Figure 1 and Figure 4 shown, a pump body 4 is fixedly connected and communicated with the rear side of the multi-pass tube 903, and the rear side of the pump body 4 is fixedly connected and communicated with the front side of the storage box 6.

[0034] In this embodiment: After controlling the pump body 4 to input the powder material inside the storage box 6 into the four processing tubes 902 through the multi-pass tube 903, by setting the four processing tubes 902, the four core pressing rods 5 move downward, and the pressing into shape of four core materials can be carried out simultaneously, realizing the multi-mode cavity core pressing of the powder material, improving the efficiency of pressing the powder material into shape, and avoiding the problem that in the prior art, the number of processing tubes for pumping the lead core powder into the processing tube for pressing the lead core powder into shape is one, which is not convenient for multi-mode cavity pressing of the lead core powder and affects the efficiency of pressing the lead core powder into shape.

[0035] Specifically, as Figure 2 shown, both sides of the bottom of the workbench 1 are fixedly connected with supporting blocks 12, and the surface of the plugging plate 801 contacts with the surface of the supporting blocks 12.

[0036] Specifically, as Figure 3 shown, four corners of the top of the second electric telescopic rod 803 are fixedly connected with support columns 13, and the top of the support columns 13 is fixedly connected with the bottom of the workbench 1.

[0037] In this embodiment: By supporting the plugging plate 801 with the supporting blocks 12, the plugging plate 801 can be made more stable, which is convenient for the core pressing rod 5 to apply stable pressure to the powder material. By fixedly connecting the bottom of the support column 13 with the top of the second electric telescopic rod 803 and fixedly connecting the top of the support column 13 with the bottom of the workbench 1, the support column 13 can support the second electric telescopic rod 803.

[0038] Specifically, as Figure 2 shown, a support plate 11 is fixedly connected between the opposite sides of the two support plates 10, and a limiting frame 2 is fixedly connected to the top of the support plate 11. The surface of the storage box 3 is movably connected with the inner wall of the limiting frame 2.

[0039] Specifically, as Figure 1 and Figure 5 shown, the bottom of the telescopic end of the first electric telescopic rod 7 is fixedly connected with a fixing plate 14, and a core pressing rod 5 used in cooperation with the processing pipe 902 is fixedly connected to the bottom of the fixing plate 14. The number of the core pressing rods 5 is four.

[0040] In this embodiment: By controlling the telescopic end of the second electric telescopic rod 803 to move leftward, the plugging plate 801 can be driven to move leftward to release the plugging of the processing pipe 902, and the core pressing rod 5 can push the formed core material inside the processing pipe 902 out of the processing pipe 902 and into the storage box 6 for storage. By moving the four core pressing rods 5 to press downward inside the processing pipe 902, the pressing of four core materials can be carried out simultaneously, realizing multi-cavity pressing and improving the efficiency of core pressing and forming of the powder material.

[0041] Working principle: By controlling the pump body 4, the powder in the storage tank 6 is input into the four processing tubes 902 through the multi-way pipe 903. Then, control the telescopic end of the first electric telescopic rod 7 to move downward, so that the fixed plate 14 drives the four core pressing rods 5 to move into the processing tubes 902 to press and form the powder. At this time, the excess air in the processing tubes 902 will be filtered through the dense hole filter exhaust port 802 and discharged from the processing tubes 902, so that the pressing of four core materials can be carried out simultaneously, realizing multi-mold cavity pressing, improving the efficiency of powder core pressing and forming. After discharging the air in the processing tubes 902, the density and quality of the core materials after pressing and forming are improved, avoiding the problem that in the existing technical solution, after the blocking cover blocks the bottom of the processing tube, when the core pressing rod moves into the processing tube and presses down, the air in the processing tube is not convenient to be discharged, affecting the quality of the core body after the lead core powder is pressed and formed. And in the existing technology, the number of processing tubes for pumping the lead core powder into the processing tube to press and form the lead core powder is one, which is not convenient for multi-mold cavity pressing and forming of the lead core powder, affecting the efficiency of pressing and forming the lead core powder. After the powder is pressed and formed into a core, control the telescopic end of the second electric telescopic rod 803 to move leftward, which can drive the blocking plate 801 to move leftward to release the block of the processing tube 902. The core pressing rod 5 can then push the formed core material in the processing tube 902 out of the processing tube 902 and fall into the storage tank 6 for storage. By supporting the blocking plate 801 with the support block 12, the blocking plate 801 can be made more stable, facilitating the stable pressing of the powder by the core pressing rod 5.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
