[0005] The main purpose of the utility model is to provide an aluminum profile extrusion device to solve the above problems.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0011] Preferably, a through opening is provided in the lower die for extruding the aluminum profile, a push block is embedded in the through opening, and a rubber layer is provided on the outer surface of the push block.

[0012] Preferably, a cylinder is fixedly provided on the upper surface of the through groove by bolts, a sliding rod is slidably provided in the cylinder, and a spring is sleeved on the periphery of the sliding rod.

[0014] Preferably, a portion of the lower end of the slide rod is slidably disposed in a cylinder, a slide groove is disposed in the cylinder, and a limit block is slidably disposed in the slide groove, and the inner side of the limit block is integrally disposed with the outer surface of the slide rod.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model provides a push block assembly in the aluminum extrusion lower die. In the initial state, the push block in the push block assembly is exposed at the through opening. In the process of the aluminum being extruded downward by the aluminum extrusion upper die, the aluminum will be pressed and thus pressurize the push block. As the aluminum is gradually pressed by the aluminum extrusion upper die, the aluminum will continue to pressurize the push block. The pressed push block will gradually be in the through opening and fit with the through opening. At the same time, the push block is pressed downward to push the slide bar downward to compress the spring. After the aluminum is pressurized, the cylinder pulls the aluminum extrusion upper die to separate from the aluminum extrusion lower die. The spring rebounds and pushes the push block upward again through the slide bar to return to its position. In the process of the push block returning to its position, the aluminum extruded above it will be pushed to move upward quickly. The aluminum quickly moves upward and can be quickly separated from the aluminum extrusion lower die and no longer fit, thereby increasing the efficiency of aluminum demoulding.

[0017] 2. The outer surface of the push block is sprayed with a rubber layer to reduce the wear on the aluminum material and better protect the aluminum material after forming;

[0018] 3. When the slide bar moves downward, the limit block will slide flexibly in the cylinder. The sliding of the limit block is restricted by the slide groove in the cylinder and can only slide up and down without causing the slide bar to rotate. This ensures that the push block will not rotate during the downward movement, avoiding the deviation from the position of the through port, thereby ensuring that the push block can reduce the position error and return to its original position smoothly.

A through groove 8 and a concave platform 7 are arranged inside the fixing seat 6, and the top inner wall of the through groove 8 is provided with a concave platform 7, and the concave platform 7 is connected with the through groove 8, and the aluminum profile extrusion lower die 3 is detachably arranged in the concave platform 7 by bolts. The inner end of the bolt is pressed against the outer surface of the aluminum profile extrusion lower die 3 or is threaded, and is used to fix the aluminum profile extrusion lower die 3 so that the aluminum profile extrusion lower die 3 is detachable; the upper surface of the top plate 2 is fixedly connected to the cylinder 9 by bolts, and the output end of the cylinder 9 is fixedly set with the aluminum profile extrusion upper die 4 by a connecting rod.

[0029] A through opening 10 is provided in the lower die 3 for extrusion of the aluminum profile, a push block 52 is embedded in the through opening 10, a rubber layer is provided on the outer surface of the push block 52, the through opening 10 and the push block 52 have the same shape, the distance between the inner wall of the through opening 10 and the outer surface of the push block 52 is 0.1-0.2 mm, the distance of the push block 52 exposed from the through opening 10 is 1-2 cm, the rubber layer is 0.3 mm, and the outer surface of the push block 52 is covered by spraying.

[0030] refer to Figure 2 The upper surface of the through slot 8 is fixed with a cylinder 51 by bolts, a slide bar 53 is slidably arranged in the cylinder 51, and a spring 54 is sleeved on the periphery of the slide bar 53. A round block 55 is integrally arranged on the outer surface of the slide bar 53, the upper end of the slide bar 53 is integrally arranged with the lower surface of the push block 52, the lower surface of the round block 55 is fixedly connected to the upper end of the spring 54, and the lower end of the spring 54 is fixedly connected to the upper end of the cylinder 51. The lower end portion of the slide rod 53 is slidably arranged in the cylinder 51. A slide groove is arranged in the cylinder 51 and a limit block 56 is slidably arranged in the slide groove. The inner side of the limit block 56 is integrally arranged with the outer surface of the slide rod 53.

The sliding of the limit block 56 is restricted by the slide groove in the cylinder 51 and can only slide up and down, and will not cause the slide rod 53 to rotate, thereby ensuring that the push block 52 will not rotate during the downward movement, avoiding the position deviation from the through port 10, thereby ensuring that the push block 52 can reduce the position error and return to its original position smoothly. The downward movement of the slide rod 53 will drive the round block 55 to move and apply pressure to the spring 54.

[0031] Working principle:

[0032] First, the aluminum material to be extruded is placed in the aluminum profile extrusion lower die 3, and then the cylinder 9 is started to push the aluminum profile extrusion upper die 4 downward to close with the aluminum profile extrusion lower die 3, and then the aluminum material will be extruded;

[0033] In the initial state, the push block 52 in the push block assembly 5 is exposed at the through opening 10. In the process of the aluminum material being extruded downward by the aluminum profile extrusion upper die 4, the aluminum material will be pressed and thus pressurize the push block 52. As the aluminum material is gradually pressed by the aluminum profile extrusion upper die 4, the aluminum material will continue to pressurize the push block 52. The pressed push block 52 will gradually be in the through opening 10 and fit with the through opening 10. At the same time, the push block 52 is pressed downward to push the slide bar 53 downward to compress the spring 54. After the aluminum material is pressurized, the cylinder 9 pulls the aluminum profile extrusion upper die 4 and the aluminum profile extrusion lower die 3 to separate. The spring 54 rebounds and pushes the push block 52 to move up again through the slide bar 53 to return to its position. In the process of the push block 52 returning to its position, the aluminum material extruded above it will be pushed to move up quickly. The aluminum material can be quickly separated from the aluminum profile extrusion lower die 3 and no longer fit, thereby increasing the efficiency of aluminum demoulding.

[0034] At the same time, the outer surface of the push block 52 is sprayed with a rubber layer to reduce the wear on the aluminum material and better protect the aluminum material after molding;

[0035] When the slide bar 53 slides downward, the limit block 56 will slide flexibly in the cylinder 51. The sliding of the limit block 56 is restricted by the slide groove in the cylinder 51 and can only slide up and down without causing the slide bar 53 to rotate. This ensures that the push block 52 will not rotate during the downward movement, avoiding position deviation from the opening 10, thereby ensuring that the push block 52 can reduce position error and return to its original position smoothly.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
