DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 3 The utility model provides an embodiment: a mold for extrusion casting, including a casting table 1, the front and rear ends of the top of the casting table 1 are fixedly connected with track rods 2, the left and right sides of the outer wall of the track rods 2 are slidably connected with a mold body 5, the top of the casting table 1 is fixedly connected with a bearing top 3, the left and right sides of the bearing top 3 are fixedly connected with a plurality of oil cylinders 4, the bottom of the far side of the two mold bodies 5 is fixedly connected with a mounting plate 8, the front ends of the adjacent sides of the two mounting plates 8 are fixedly connected with an electric telescopic rod 9, the adjacent sides of the two mounting plates 8 are fixedly connected with a plurality of limit plates 10, and the middle ends of the adjacent sides of the two mounting plates 8 are fixedly connected A slideway 11 is connected, a steep slope block 12 is fixedly connected to the output end of the electric telescopic rod 9, an assembly plate 13 is fixedly connected to the middle of the far side of the two mold bodies 5, a displacement rod 14 is slidably connected to the inner wall of the far side of the two mold bodies 5, and a retaining ring 15 is fixedly connected to the far side of the two displacement rods 14, and a spring 16 is provided on the far side of the two assembly plates 13, and the spring 16 is sleeved on the displacement rod 14, and a contact plate 17 is fixedly connected to the proximal side of the two displacement rods 14, the inner wall of the mold body 5 is provided with a de-impurity component, the top of the bearing top 3 is provided with an injection component, and a guide groove 19 is provided at the bottom of the casting table 1.

[0030] The mold body 5 is fixedly connected to the output end of the oil cylinder 4, and the output power of the oil cylinder 4 pushes the mold bodies 5 on both sides to approach each other under the limit of the track rod 2, and the sealing member provided in contact therebetween ensures that a sealed cavity is formed inside the mold bodies 5 after the left and right sides are merged;

[0031] After the aluminum liquid is formed, the mold body 5 is slidably connected to the left and right sides of the inner wall of the bearing top 3. As the cylinder 4 contracts, the mold body 5 will return to the initial position on the top of the casting table 1, thereby opening the electric telescopic rod 9, and the directional wheel is movably connected to the adjacent side of the two steep slope blocks 12. The steep slope blocks 12 are pushed to slide on the slideway 11 by the electric telescopic rod 9, so that the directional wheel on one side of the positioning ring 15 can push the displacement rod 14 to move, thereby pushing the formed workpiece out from the inside of the mold body 5 through the contact plate 17, and collecting them uniformly through the guide groove 19. Automation is realized in this process without manual operation, effectively improving the processing and casting efficiency.

[0032] Reference Figure 3 The steep slope block 12 is slidably connected to the outer wall of the slide 11, and the displacement of the steep slope block 12 is limited by the slide 11. The retaining ring 15 is slidably connected to the adjacent side of multiple limiting plates 10. The distant sides of the two retaining rings 15 are each provided with a directional wheel. The directional wheel provided on one side of the retaining ring 15 will always slide on the adjacent side of the two limiting plates 10, thereby maintaining the sliding push stability.

[0033] Reference Figure 2 The impurity removal component includes an injection hole 6, and a plurality of injection holes 6 are opened on the top of the mold body 5. A slag collecting groove 7 is opened on the adjacent side of the two mold bodies 5.

[0034] Reference Figure 1 The injection assembly includes a feeding device body 18, and the feeding device body 18 is arranged at the top middle end of the bearing top 3.

[0035] A gas injection pipe is provided at the middle bottom of the feeding device body 18, and inert gas is injected into the slag collecting tank 7. The mold cavity is protected by injecting inert gas to reduce the occurrence of oxidation reaction after the subsequent aluminum liquid enters. A plurality of injection pipes are provided at the bottom of the feeding device body 18, and during the injection process, the liquids in the plurality of injection pipes are connected to the injection hole 6, and after the gas injection is completed, high-temperature aluminum liquid is injected into the mold body 5 through the injection hole 6. After the injection is completed, with the protection of the inert gas, the formation of the oxide layer can be effectively reduced, and the bubbles generated on the inner wall of the mold body 5 during the injection process can be discharged from the slag collecting tank 7 by air pressure.

[0036] Working principle: When the staff uses this mold to perform extrusion casting on the molten metal, they first use the power output by the oil cylinder 4 to push the mold bodies 5 on both sides to approach each other under the limit of the track rod 2, and use the seals set in contact between them to ensure that a sealed cavity is formed inside the mold body 5 after the left and right sides are merged. Then the feeding device body 18 can be opened, and inert gas is injected into the slag collecting tank 7 through the gas injection pipe connected to the middle part of the feeding device body 18. The mold cavity is protected by injecting inert gas to reduce the occurrence of oxidation reaction after the subsequent aluminum liquid enters, and during the injection process, multiple injection tube liquids are connected to the injection hole 6, and after the gas injection is completed, high-temperature aluminum liquid is injected into the mold body 5 through the injection hole 6. After the injection is completed, the protection of the inert gas can effectively reduce the formation of an oxide layer, and the bubbles generated on the inner wall of the mold body 5 during the injection process can be discharged from the slag collecting tank 7 by air pressure.

[0037] After the aluminum liquid is formed, as the oil cylinder 4 contracts, the mold body 5 will return to the initial position on the top of the casting table 1, so that the electric telescopic rod 9 can be opened, and the steep slope block 12 can be pushed to slide on the slide 11 by the electric telescopic rod 9, so that the directional wheel on one side of the positioning ring 15 can push the displacement rod 14 to move, so that the formed workpiece can be pushed out from the inside of the mold body 5 by the push of the contact plate 17, and collected uniformly through the guide groove 19. In this process, automation is realized without manual operation, which effectively improves the processing and casting efficiency.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
