[0021] Reference Figure 1-Figure 11 In an embodiment of the present invention, a liquid immersion mode automobile chassis injection molding device is provided, which at least includes an injection pool 1, a mold assembly, a lifting mechanism and a pair of brackets.

[0022] Reference Figure 1 The injection tank 1 is provided with a main groove 3, a cooling groove 4, and an auxiliary groove 9. The main groove 3, the cooling groove 4, and the auxiliary groove 9 are separated by a partition, and a notch is provided on the partition. A liquid infusion tube 2 is connected to one side of the main groove 3. Specifically, two partitions can divide the internal space of the injection tank 1 into three parts, the middle part is the main groove 3, and the two sides are respectively the cooling groove 4 and the auxiliary groove 9. The mold assembly includes an upper mold 7 and a lower mold 8 that cooperate with each other. The lower mold 8 is fixedly installed in the main groove 3. A top plate 5 is provided above the main groove 3. Both ends of the top plate 5 extend downward and are fixedly connected to both ends of the injection tank 1. The upper mold 7 is installed on the top plate 5 through a first hydraulic cylinder 6. The first hydraulic cylinder 6 is fixedly installed on the top plate 5. The upper mold 7 is installed at the output end of the first hydraulic cylinder 6. The first hydraulic cylinder 6 is used to drive the upper mold 7 up and down so that the upper mold 7 and the lower mold 8 cooperate with each other. An inwardly concave injection groove 15 is provided in the lower mold 8. The injection groove 15 is used for injection molding automobile chassis structural parts.

[0023] Reference Fig.10 and 11, both ends of the injection groove 15 are inserted with a push rod 30, and an oil delivery pipe 34 is also provided on one side of the push rod 30 in the injection groove 15. The lifting mechanism is arranged below the lower mold 8 and is used in conjunction with the push rod 30. A fixed plate 13 is fixedly installed below the lower mold 8 in the main groove 3, and the lifting mechanism is installed on the fixed plate 13. The lifting mechanism includes a traction shaft 32 and a second hydraulic cylinder 29. A limiting groove 33 is provided on the fixed plate 13. The second hydraulic cylinder 29 is fixedly connected to one side of the fixed plate 13, and both driving ends of the second hydraulic cylinder 29 are fixedly connected with a slider 35. The two sliders 35 are slidably installed at both ends of the limiting groove 33, respectively. One end of the traction shaft 32 is rotatably connected to the lower end of the push rod 30, and the other end of the traction shaft 32 is movably connected to one side of the slider 35. When it is necessary to lift the injection molded chassis, the second hydraulic cylinder 29 pulls the two sliders 35 respectively through the two driving ends. In the process of moving the sliders 35, the lower end of the traction shaft 32 will be driven to move. Since the upper end of the traction shaft 32 is restricted by the push rod 30, the traction shaft 32 will produce an angle change as its lower end moves, that is, the upper end of the traction shaft 32 moves up and down. As the traction shaft 32 moves, the push rod 30 can be lifted up, and then the chassis can be lifted up.

[0024] The bottom of the injection groove 15 is provided with a top groove for use with the ejector 30, one side of the top groove is provided with an extrusion groove, the top groove is connected with the extrusion groove, the ejector 30 is slidably inserted in the top groove, the oil delivery pipe 34 is inserted in the extrusion groove, the upper end of the ejector 30 is fixedly connected with a sealing block 28, one side of the sealing block 28 passes through the top groove and is stuck in the upper end of the extrusion groove. When the ejector 30 lifts the chassis, the sealing block 28 will also rise and separate from the extrusion groove, and the oil delivery pipe 34 will be exposed. When demolding, oil is gradually transported to the inside through the oil delivery pipe 34, and a good demolding effect is achieved with the input of oil.

[0025] One side of the lower half of the top groove for inserting the top rod 30 is inclined toward the side of the traction shaft 32, and the other side of the top groove is provided with a semi-arc U-shaped sleeve 31. The lower half of the top groove is set as a relatively spacious inclined space to facilitate the traction shaft 32 to lift the top rod 30, and the other side is provided with a U-shaped sleeve 31 for limiting.

[0026] Reference Figure 1 and Figure 2 , two brackets 11 are fixedly mounted on the inner walls at both ends of the main groove 3 (the number of the brackets 11 is not given in the figure). Figures 4 to 7 A slide rail 26 is provided on the bracket 11, and a first cylinder 12 is rotatably connected to the bracket 11. A U-shaped shaft 20 is movably connected to the driving end of the first cylinder 12. Two clamping mechanisms are provided on the U-shaped shaft 20, and the clamping mechanisms are used to receive the injection molding base. A moving mechanism is also provided on the bracket 11, and the moving mechanism is used to move the injection molding base.

[0027] The clamping mechanism includes a first rotating shaft 23, a second rotating shaft 24 and a clamping shaft 19. The two ends of the first rotating shaft 23 are rotatably connected to the U-shaped shaft 20 and the second rotating shaft 24 respectively. The clamping shaft 19 is rotatably connected to the end of the second rotating shaft 24 away from the first rotating shaft 23. A return spring 25 is provided on one side of the connection between the U-shaped shaft 20 and the first rotating shaft 23 and the connection between the first rotating shaft 23 and the second rotating shaft 24. The return spring 25 will make the first rotating shaft 23, the second rotating shaft 24 and the clamping shaft 19 tend to maintain a stable relative position relationship. After the clamping mechanism sets up the chassis, it will move to one side, and will encounter obstruction of the limiting column 16 during the movement. The first rotating shaft 23 and the U-shaped shaft 20 are rotationally connected, and the first rotating shaft 23 and the second rotating shaft 24 are also rotationally connected. In addition, an elastic reset spring 25 is provided at the connection. When encountering obstruction of the limiting column 16, mutual deflection and folding will occur, so that the clamping mechanism can smoothly pass through the limiting column 16. After passing through the limiting column 16, under the elastic reset action of the reset spring 25, it returns to its original state and carries the chassis again. Multiple clamping mechanisms are symmetrically arranged. When a single clamping mechanism contacts the limiting column 16, the remaining clamping mechanisms continue to carry the chassis to ensure the stability of the structure.

[0028] The moving mechanism includes a second cylinder 17 and a limiting shaft 18. A moving shaft 22 is provided at one end of the U-shaped shaft 20. The moving shaft 22 is slidably arranged in the slide rail 26. A connecting block 21 is slidably clamped in the moving shaft 22. The second cylinder 17 is clamped on the connecting block 21. The limiting shaft 18 is inserted into the U-shaped shaft 20 for sliding up and down movement. The driving end of the second cylinder 17 is sleeved on the limiting shaft 18, and the driving end of the first cylinder 12 is rotationally connected to one side of the connecting block 21.

[0029] It can be seen from the above description that the movement track of the U-shaped shaft 20 is determined by the slide rail, so the specific shape of the slide rail is designed according to the movement track that the U-shaped shaft 20 needs to meet in actual needs. Its movement track usually includes up and down movement and left and right movement. Figure 6 and Figure 7 In one example, the portion of the slide rail 26 close to the U-shaped shaft 20 is a U-shaped structure with an opening facing upward, and the portion away from the U-shaped shaft 20 is arranged horizontally. When the moving shaft 22 moves in the U-shaped structure of the slide rail 26, it will move up and down, thereby driving the U-shaped shaft 20 to move up and down.

[0030] When the chassis needs to be moved out from between the upper mold 7 and the lower mold 8, the second cylinder 17 drives the limit shaft 18 to move through the extension and contraction of the driving end, and the limit shaft 18 drives the entire U-shaped shaft 20 to move, thereby realizing the function of removing the chassis. Since the clamping mechanism will move up and down when contacting the chassis, a limit shaft 18 is set between the driving end of the second cylinder 17 and the U-shaped shaft 20, and the limit shaft 18 is used to adapt to the upper and lower height differences.

[0031] A power-on spring 27 is provided on one side of the first cylinder 12, one end of the power-on spring 27 is fixedly connected to the first cylinder 12, the other end of the power-on spring 27 is fixedly connected to the bracket 11, and the power-on spring 27 is provided on one side of the connection point between the first cylinder 12 and the bracket 11. The clamping mechanism moves up and down when approaching the chassis, and the direction of movement is controlled to be upward or downward by energizing and de-energizing the power-on spring 27, and the driving end of the first cylinder 12 controls the direction of movement to be forward or backward.

[0032] The clamping shaft 19 is surrounded by a plurality of supporting legs, each of which has a flat lower surface and an inclined upper surface for supporting the chassis. The track of the slide rail 26 is the moving track of the clamping shaft 19 extending from the outside into the bottom of the chassis. The injection molding groove 15 includes a molding space and a non-molding space.

[0033] Two first hydraulic cylinders 6 are symmetrically fixedly installed on the top plate 5, and the driving ends of the two first hydraulic cylinders 6 are respectively fixedly connected with driving shafts 14. The lower ends of the two driving shafts 14 are fixedly connected to the upper mold 7. The bottom of the lower mold 8 is supported by the support column 10 and installed in the main groove 3. A plurality of limiting columns 16 are fixedly connected to the edge position of the lower mold 8. The limiting columns 16 pass through the upper mold 7 and are fixedly connected to the top plate 5.

[0034] During the injection molding, the first hydraulic cylinder 6 moves the upper mold 7 downward by extending the driving shaft 14 at the driving end, so that the upper mold 7 and the lower mold 8 are closed. Before closing the mold, the closed internal space is first inflated from top to bottom to remove the internal impurities, and then the material is injected into the internal injection groove 15 through the injection tube. After the injection molding is completed, the oil is transported to the main groove 3 through the infusion tube 2. During the oil transport process, the oil can cool the upper mold 7 and the lower mold 8. After cooling and molding, the mold is opened, and the first hydraulic cylinder 6 is driven again to separate the upper mold 7 and the lower mold 8; The lifting mechanism is started, and the second hydraulic cylinder 29 drives the traction shafts 32 at both ends. As the traction shafts 32 move, the push rods 30 move upward, and the push rods 30 drive the sealing blocks 28 to move upward, and demolding can begin from both ends of the molding chassis. After the sealing blocks 28 are lifted to leave the top groove and the extrusion groove, oil is transported inward through the oil pipe 34. The oil is slowly transported into the injection groove 15. The oil will spread within the range of the injection groove 15 and start to spread from the bottom of the molding chassis, thereby separating the molding chassis from the inner wall of the injection groove 15, and the molding chassis will be lifted up in the injection groove 15 as the oil is input and squeezed.

[0035] Under the action of the oil, the molding chassis continuously moves upward, and at the same time, the driving end of the first cylinder 12 extends and retracts. When the first cylinder 12 extends and retracts, it cooperates with the energized spring 27. Under the pushing action of the driving end of the first cylinder 12, the second cylinder 17 and the movable shaft 22 slide in the slide rail 26, so that the U-shaped shaft 20 approaches the mold, and the clamping shaft 19 is extended into the injection groove 15 of the lower mold 8, so that the clamping shaft 19 is located at the edge of the molding chassis. When the molding chassis floats to the edge of the injection groove 15, the clamping shaft 19 continues to move, and the various legs of the clamping shaft 19 can just be clamped under the molding chassis. The various clamping mechanisms cooperate with each other to effectively lift the molding chassis and remove it from between the upper mold 7 and the lower mold 8.

[0036] The injection molding groove 15 includes a molding space and a non-molding space. The molding space is used for injection molding when the mold is closed, and the non-molding space will be closed. When the mold is demolded, both the molding space and the non-molding space are exposed. The molding chassis is embedded in the molding space, and the non-molding space is used for the deepening of the clamping mechanism. When the edge of the molding chassis comes out of the molding space, the clamping shaft 19 can move in the non-molding space to lift the molding chassis.

[0037] When the clamping shaft 19 contacts the chassis, the infusion tube 2 will continue to pour oil into the main groove 3, and the oil will gradually cover the lower mold 8 and contact the chassis. The oil provides effective buoyancy for the chassis and the force is balanced. During the demolding process, the balanced extrusion of the oil causes the molded chassis to separate from the inner wall of the injection groove 15. When moving outward, the oil provides buoyancy, which effectively avoids the problem of deformation of the molded chassis due to uneven force.

[0038] The forming chassis can be directly transferred to the cooling tank 4 by the moving mechanism for storage, and then transitioned along the notch. After the forming chassis is transferred, the clamping mechanism returns to its original position and resets. The oil in the main tank 3 is recovered through the infusion tube 2. During the recovery process, the oil in the cooling tank 4 does not need to be recovered. The notch ensures the connectivity between the main tank 3 and the cooling tank 4. The auxiliary tank 9 is used to reserve space for the second cylinder 17.

[0039] In summary, the liquid immersion mode automobile chassis injection molding equipment provided by the present invention can ensure that the automobile chassis structural parts are subjected to uniform force during demolding, thereby greatly reducing the possibility of deformation or damage to the chassis structural parts, improving the molding quality of the chassis structural parts, and solving the problem of low demolding quality of current automobile chassis injection molding equipment.
