DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0031] In order to save manpower and improve efficiency, as one embodiment of the utility model, as Figure 1 , Figure 2 ,Figure 3 , Figure 4 , Figure 5 As shown, the pressure-resistant aluminum profile die-casting device of this utility model includes a processing table 1, a connecting cover 2, a shielding cover 3, and a sliding block 32. A fixed mold 11 is installed on one outer wall of the processing table 1, and a moving mold 14 is slidably installed on one outer wall of the fixed mold 11. A connecting cover 2 is provided between the fixed mold 11 and the moving mold 14. Shielding covers 3 are provided on both outer walls of the connecting cover 2. Atomizing nozzles 22 are provided inside the connecting cover 2. Fixed seats 25 are symmetrically installed on both outer walls of the connecting cover 2. Limiting rods 27 are interference-fitted inside the fixed seats 25. Support frames 33 are screwed to the upper and lower outer walls of the shielding cover 3. Rollers 34 are rotatably installed inside the support frames 33. When the rollers 34 move outside the fixed mold 11 or the moving mold 14, they will not contact the mold cavity.

[0032] In use, the atomizing nozzle 22 can uniformly spray the release agent onto the surfaces of the fixed mold 11 and the moving mold 14 before the die casting process. The connecting cover 2, together with the shielding cover 3, can shield the fixed mold 11 and the moving mold 14, ensuring a seal between the fixed mold 11 and the moving mold 14 during the spraying of the atomized release agent. This limits the spraying range, prevents the atomized release agent from scattering, and ensures the spraying effect of the atomized release agent on the inner walls of the mold cavities of the moving mold 14 and the fixed mold 11. When the connecting cover 2 is pushed vertically by the hydraulic rod 13, it can move the connecting cover 2 and the shielding cover 3 between the fixed mold 11 and the moving mold 14. The roller 34 can assist the movement of the shielding cover 3, preventing the shielding cover 3 from scratching the fixed mold 11 and the moving mold 14 during the movement. The limiting rod 27 provides a limiting and guiding function for the movement of the shielding cover 3, ensuring the stability and accuracy of the movement of the shielding cover 3.

[0033] To drive movement, for example, such as Figure 1 As shown, a hydraulic cylinder 15 is installed on the outer wall of the processing table 1 on the side away from the fixed mold 11. The hydraulic cylinder 15 is connected to the outer wall of the moving mold 14 by screws. The upper and lower outer walls of the fixed mold 11 and the moving mold 14 are both designed with an inclined shape.

[0034] In use, the hydraulic cylinder 15 can drive the moving mold 14 to move horizontally, thereby enabling the moving mold 14 to accurately close and separate from the fixed mold 11, ensuring the smooth progress of the die casting process and ensuring the forming accuracy of the die casting. The inclined design can assist the movement of the roller 34. When the roller 34 moves vertically and contacts the inclined surface, the shield 3 is squeezed and will move horizontally, which helps the shield 3 to move smoothly between the fixed mold 11 and the moving mold 14.

[0035] To adjust the usage location, for example, such as Figure 1 As shown, a fixing plate 12 is screwed to the upper end of the outer wall of one side of the processing table 1. Hydraulic rods 13 are installed on both sides of the outer wall of the fixing plate 12. The lower end of the outer wall of the hydraulic rod 13 is screwed to the upper end of the outer wall of the connecting cover 2.

[0036] In use, the fixed plate 12 ensures the stability of the use position of the hydraulic rod 13, and the height and position of the connecting cover 2 can be conveniently adjusted through the extension and retraction of the hydraulic rod 13. The hydraulic rod 13 and the hydraulic cylinder 15 are controlled by an external hydraulic control system, and the extension and retraction of the push rod part of the hydraulic rod 13 and the hydraulic cylinder 15 can be controlled respectively.

[0037] In order to fix the use position, as shown in Figure 3 , the connecting column 23 is installed on the outer wall of the upper end of the atomizing nozzle 22, and is screwed between the inner wall of the connecting cover 2 and the upper end of the connecting column 23. The air pipe 24 is inserted and installed on one side of the outer wall of the upper end of the atomizing nozzle 22, and the flange is installed on the air pipe 24 penetrating through one end of the outer wall of the connecting cover 2.

[0038] In use, the connecting column 23 ensures the stability of the installation position of the atomizing nozzle 22, ensures the uniformity and stability of the release agent spraying, and the air pipe 24 can be connected with the release agent supply device through the flange. The external release agent supply device can transport the release agent to the inside of the atomizing nozzle 22 through the air pipe 24, and the atomized release agent sprayed through the atomizing nozzle 22 can be sprayed towards the mold cavity to realize the spraying of the release agent in the mold cavity.

[0039] In order to seal, as shown in Figure 2 , the sealing gasket 31 is bonded and fixed to one end of the outer wall of the shielding cover 3, and the fixed mold 11 and the movable mold 14 are in contact with the sealing gasket 31. The sealing ring 21 is bonded and fixed to the outer wall of the connecting cover 2 on both sides, and the sealing ring 21 is in contact with the inner wall of the shielding cover 3.

[0040] In use, the two shielding covers 3 can maintain the sealing between the fixed mold 11 and the movable mold 14 through the sealing gasket 31, and the sealing ring 21 can maintain the sealing between the connecting cover 2 and the shielding cover 3. Therefore, when the connecting cover 2 and the shielding cover 3 are located between the fixed mold 11 and the movable mold 14, the shielding and sealing between the fixed mold 11 and the movable mold 14 can be realized.

[0041] In order to control the moving track, as shown in Figure 4 , the sliding block 32 is installed on the outer wall of the shielding cover 3 in a rectangular array, the sliding block 32 is slidingly installed on the outer side of the limiting rod 27, the nut 29 is screwed on the outer wall of the limiting rod 27, and the nut 29 is in contact with the outer wall of the sliding block 32.

[0042] In use, the nut 29 can limit the sliding track of the sliding block 32 on the outer side of the limiting rod 27, so that the shielding cover 3 can accurately stay at the required position, and the limiting rod 27 cooperates with the sliding block 32 to ensure the stability and smoothness of the horizontal track of the shielding cover 3.

[0043] In order to keep the position relatively stable in use, for example, as shown in Figure 4 The spring 28 is arranged outside the limiting rod 27, and the sliding block 32 is elastically connected between the spring 28 and the fixed seat 25; the fixed seat 25 is screw-connected between the outer wall of the connecting cover 2 through the fixed members 26 arranged on the outer walls of the upper and lower sides of the fixed seat 25.

[0044] In use, the spring 28 elastically supports the sliding block 32, so that the position of the sliding block 32 outside the limiting rod 27 is relatively stable; during the vertical movement of the shielding cover 3, the roller 34 is first in contact with the inclined surface of the movable die 14 or the fixed die 11, and then rolls along the inclined surface, thereby driving the shielding cover 3 to move away from the movable die 14 and the fixed die 11, so that the shielding cover 3 is prevented from contacting the movable die 14 or the fixed die 11 during the movement; at this time, the spring 28 is in a compressed state, and when the upper and lower rollers 34 move to the corresponding upper and lower inclined surfaces, the spring 28 releases the elastic force to push the shielding cover 3 to move until the sealing gasket 31 is in contact with the outer walls of the movable die 14 and the fixed die 11, so that the shielding cover 3 cooperates with the connecting cover 2 to shield the gap between the movable die 14 and the fixed die 11; when the hydraulic rod 13 moves upward, the roller 34 and the shielding cover 3 repeat the above movement steps until the shielding cover 3 is separated from the movable die 14 and the fixed die 11.

[0045] In use, the hydraulic rod 13 on the fixed plate 12 is started to be elongated, thereby pushing the connecting cover 2 to move vertically downward, and the connecting cover 2 drives the shielding covers 3 on both sides to move together; the shielding cover 3 is assisted to move through the rollers 34 in the upper and lower supporting frames 33, and at the same time, the limiting rod 27 provides limiting and guiding for the movement of the shielding cover 3; when the roller 34 moves vertically and is in contact with the inclined surfaces on the upper and lower sides of the fixed die 11 and the movable die 14, the shielding cover 3 is extruded to move horizontally until it moves to between the fixed die 11 and the movable die 14; the spring 28 elastically pushes the shielding cover 3 to move, and the shielding cover 3 is in close contact with the fixed die 11 and the movable die 14 through the sealing gasket 31, thereby shielding the spraying range.

[0046] The mold release agent supply device is started to supply the mold release agent to the inside of the atomizing nozzle 22 through the air pipe 24; the mold release agent is atomized by the atomizing nozzle 22 and uniformly sprayed on the surfaces of the fixed die 11 and the movable die 14 and the inner walls of the mold cavities; and then the connecting cover 2 is driven by the hydraulic rod 13 to move upward to reset.

[0047] The hydraulic cylinder 15 is started to drive the movable die 14 to move horizontally and accurately close the fixed die 11, so that the molten aluminum alloy liquid is injected into the mold cavities formed by the fixed die 11 and the movable die 14; under the action of high pressure, the aluminum alloy liquid rapidly fills the mold cavities and is solidified to form a shape.
