Technical Field

[0001] The invention patent relates to the technical field of aluminum profile processing, and in particular to an automatic aluminum profile extrusion machine die replacement device. Background Art

[0002] An extruder is a device that forms a workpiece by extrusion. An aluminum profile extruder usually uses a mold, cuts and pulls it, and then manually replaces the mold, and then uses the next mold to continue extrusion molding. Therefore, in the past, it was necessary to manually replace the mold, which was inefficient. The existing patent CN113510959B mentions an extruder with automatic mold change, which replaces the mold through a workpiece clamping mechanism. Although the mold can be automatically replaced, it will squeeze the mold during clamping and damage the mold. Therefore, it is necessary to develop an aluminum profile extruder device that can automatically replace the mold. Summary of the invention

The extrusion mechanism 4, the die replacement mechanism 5 and the traction mechanism 6 are all arranged on the longitudinal sliding guide rail 1, the die replacement mechanism 5 is arranged at the front end of the extrusion mechanism 4, and the traction mechanism 6 and the cutting mechanism 7 are arranged at the front end of the die replacement mechanism 5; the die replacement mechanism 5 comprises a sliding die seat 51, a waste pushing mechanism 52 and a pulling mechanism 53, the sliding die seat 51 is provided with a groove 511, a die 55 is inserted in the groove 511, the center of the die 55 is a cavity 551, and the cavity 551 is partially recessed, the sliding die seat 51 and the die 55 are provided with a through groove, in which a positioning pin 512 is inserted, a roller is installed at the bottom of the sliding die seat 51, and is rolled on the transverse sliding guide rail 3, and a traction handle 513 is arranged on the side of the sliding die seat 51 perpendicular to the transverse sliding guide rail 3. The waste pushing mechanism 52 is slidably arranged on the longitudinal sliding side guide rail 2, and the pulling mechanism 53 is slidably arranged on the transverse sliding guide rail 3. During use, after the mold 55 is placed in the groove 511 of the sliding mold seat 51, the positioning pin 512 is inserted to fix the mold 55 and the sliding mold seat 51 together, which can prevent the mold 55 from sliding and causing displacement deviation.

[0028] Furthermore, the waste pushing mechanism 52 includes a base bracket 521, which is slidably arranged on the longitudinal sliding side guide rail 2, a propulsion cylinder 522 is fixedly installed above the base bracket 521 and in a direction parallel to the longitudinal sliding side guide rail 2, a push plate 523 is arranged at the front end of the propulsion cylinder 522, and a waste pushing block 524 is fixedly installed at the front end of the push plate 523. The push plate 523 and the waste pushing block 524 can effectively realize the preliminary treatment of waste removal and the preliminary treatment of mold removal, so as to facilitate subsequent replacement.

[0029] Furthermore, the size of the waste pusher 524 is consistent with the concave size of the cavity 551. The push plate 523 pushes out the positioning pin 512, and the size of the waste pusher 524 is consistent with the concave size of the cavity 551, pushing the excess aluminum profile waste out of the cavity 551 of the mold 55, making it convenient to take out the positioning pin 512 and the excess aluminum profile waste later.

[0030] Furthermore, the pulling mechanism 53 includes a sliding vehicle 532, the bottom of which is provided with rollers, and is slidably arranged on the transverse sliding guide rail 3. The sliding vehicle 532 is driven by a motor, and a hook groove 5321 is provided in the middle of the sliding vehicle 532, and a pulling hook 531 is rotatably hinged in the hook groove 5321, and the horizontal position of the pulling mechanism 53 is lower than the height of the chassis of the sliding mold seat 51. The used sliding mold seat 51 is pulled by the pulling mechanism 53, and specifically, the pulling mechanism 53 moves forward to the position of the sliding mold seat 51. Since the pulling hook 531 in the pulling mechanism 53 is rotatably hinged at the hook groove 5321, the pulling hook 531 is rotated and raised, hooking the traction handle 513 of the sliding mold seat 51 and pulling it in the forward direction, and the used sliding mold seat 51 is pulled away from the waste pushing mechanism 52.

[0031] Furthermore, the extrusion mechanism 4 is provided with a large extrusion cylinder 41, which is directly opposite to the cavity 551 of the mold 55, and an extrusion sleeve 54 is sleeved in front of the mold 55. The extrusion sleeve 54 can fix the mold and the aluminum bar profile, making it convenient for the extrusion mechanism 4 to advance and the profile to be formed.

[0032] Furthermore, a pointer 42 is provided on the side of the extrusion mechanism 4. The pointer 42 can reflect the forward position, which is convenient for the staff to record the operation extrusion length.

[0033] Furthermore, the traction mechanism 6 is slidably arranged on the longitudinal sliding guide rail 1 .

[0034] Furthermore, the cutting mechanism 7 is slidably arranged on the longitudinal sliding side guide rail 2 .

[0035] Furthermore, the traction mechanism 6 includes a clamping plate 61, which is driven by a cylinder, and can effectively pull the extruded aluminum profile and ensure the continuity of its operation.

[0036] The working principle of the present invention is as follows: first, multiple related molds 55 are selected, and after the molds 55 are placed in the grooves 511 of the slide mold seat 51, the positioning pins 512 are inserted to fix the molds 55 and the slide mold seat 51 together to prevent the molds 55 from sliding and causing displacement deviation, and then the slide mold seats 51 are arranged in the order of use, and the equipment is started after they are arranged. The heated aluminum rod is placed in the extrusion mechanism 4, and the aluminum profile passes through the extrusion mechanism 4 and reaches the mold 55 through the extrusion sleeve 54, extruding the aluminum profile, and the aluminum profile reaches the traction mechanism 6, is pressed and pulled back by the clamping plate 61, and is cut by the cutting mechanism 7 after reaching the appropriate length.

[0037] Since the mold cavity 551 of the mold 55 is partially recessed, the used sliding mold seat 51 is pulled by the pulling mechanism 53, specifically, the pulling mechanism 53 moves toward the position of the sliding mold seat 51, and since the pulling hook 531 in the pulling mechanism 53 is rotatably hinged at the hook groove 5321, the pulling hook 531 is rotated and raised, hooking the traction handle 513 of the sliding mold seat 51 and pulling it in the forward direction, the used sliding mold seat 51 is pulled away from the waste pushing mechanism 52, and the pushing cylinder 522 of the waste pushing mechanism 52 pushes the pushing plate 523 and the waste pushing block 524, and the pushing plate 523 pushes out the positioning pin 512, and the size of the waste pushing block 524 is consistent with the mold cavity The recessed sizes of 551 are consistent, and the excess aluminum profile waste is pushed out of the cavity 551 of the mold 55, which is convenient for taking out the positioning pin 512 and the excess aluminum profile waste and replacing the remaining molds 55; at the same time, the horizontal position of the pulling mechanism 53 is lower than the chassis height of the sliding mold seat 51, and the pulling mechanism 53 changes direction and moves forward to pull the next sliding mold seat 51 to be used, so as to realize seamless connection and automatic replacement of the mold, and no manual replacement is required, which greatly reduces manpower consumption. The automatic mold replacement is realized by the pulling mechanism 53, and at the same time, the preliminary processing of the waste aluminum after the automatic mold replacement and the preliminary processing of the mold removal can be realized, which is convenient for subsequent replacement.
