Technical Field

[0001] The utility model relates to the field of aluminum profile production, and particularly relates to an extruder. Background Art

[0002] An extruder is a device used to process materials (usually plastics, metals or foods) into different shapes by heating and applying pressure. Its basic working principle is to heat the raw materials to a molten state and then extrude them through a die or orifice to form the required shape. When producing aluminum profiles with complex shapes, people use extruders for production.

[0003] When using an extruder to produce aluminum profiles, aluminum profiles with different specifications and shapes need to be produced in cooperation with corresponding dies. However, when replacing the die of the existing extruder, it usually takes a long time, resulting in a long downtime of the extruder, which is not conducive to improving the production efficiency of aluminum profiles. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the die replacement time of the current extruder is relatively long, which affects the production efficiency of aluminum profiles.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: An extruder, comprising an extruder main body, a long slide rail, a first mounting member, a die sleeve, a die and a die pad. A moving table is arranged on one side of the extruder main body. A first short slide rail and a second short slide rail adapted to the long slide rail are respectively fixed on the top of the moving table. The first short slide rail is aligned with the long slide rail. A second mounting member slides on the surface of the second short slide rail. A horizontal moving component for driving the displacement of the moving table is arranged on one side of the extruder main body. A positioning component is arranged on the moving table. A hydraulic cylinder is fixed on the other side of the extruder main body. A connecting sleeve is fixed at the output end of the hydraulic cylinder.

[0008] Preferably, the horizontal moving component comprises an installation table. Two guide rails are symmetrically fixed on the top of the installation table. The moving table is slidably connected on the two guide rails. An electric push rod is fixed on the top of the installation table. A connecting plate is fixed at the output end of the electric push rod, and the top of the connecting plate is fixed at the bottom of the moving table.

[0009] Preferably, the positioning assembly includes a first spacer bar and a second spacer bar respectively fixed to the top of the mobile platform. The first spacer bar is located between the first short slide rail and the second short slide rail, and the second spacer bar is located on the other side of the second short slide rail.

[0010] Preferably, positioning blocks are fixed to one end of each of the first short slide rail and the second short slide rail, and a laser distance sensor is disposed above the positioning block of the first short slide rail.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1 - 6 shown, the present invention provides an extruder, including an extruder main body 1, a long slide rail 2, a first mounting part 3, a die sleeve 14, a die 15 and a die cushion 16. A moving table 4 is arranged on one side of the extruder main body 1. A first short slide rail 5 and a second short slide rail 6 adapted to the long slide rail 2 are respectively fixed on the top of the moving table 4. The first short slide rail 5 is aligned with the long slide rail 2. A second mounting part 7 slides on the surface of the second short slide rail 6. A horizontal moving component 8 for driving the displacement of the moving table 4 is arranged on one side of the extruder main body 1. A positioning component 9 is arranged on the moving table 4. A hydraulic cylinder 10 is fixed on the other side of the extruder main body 1. A connecting sleeve 11 is fixed at the output end of the hydraulic cylinder 10. A T-shaped groove 12 is opened in the middle of the connecting sleeve 11.

[0024] The effect achieved by the entire Embodiment 1 is that the first mounting part 3 and the second mounting part 7 can respectively install the corresponding die 15. When the die 15 needs to be replaced, the hydraulic cylinder 10 can directly push the first mounting part 3 out of the extruder main body 1 and move it to the moving table 4. With the cooperation of the positioning component 9 and the horizontal moving component 8, the second mounting part 7 with the new die 15 installed can be quickly replaced with the first mounting part 3. Under the reset movement of the hydraulic cylinder 10, the die 15 replacement operation can be quickly completed, greatly shortening the die 15 replacement time and the shutdown time of the extruder main body 1.

[0025] Embodiment 2: As Figures 1 - 6As shown, a T-shaped connecting block 13 adapted to the T-shaped groove 12 is fixed on one surface of the first mounting member 3 and the second mounting member 7, and the T-shaped connecting block 13 on the first mounting member 3 is engaged in the T-shaped groove 12; a pressing cylinder is slidably connected in the extruder body 1, a die 15 is installed in a die sleeve 14, and the die sleeve 14 and a die pad 16 are installed in the first mounting member 3; the horizontal moving assembly 8 includes a mounting table 801, two guide rails 802 are symmetrically fixed on the top of the mounting table 801, a moving table 4 is slidably connected on the two guide rails 802, an electric push rod 803 is fixed on the top of the mounting table 801, an output end of the electric push rod 803 is fixed with a connecting plate 804, and the top of the connecting plate 804 is fixed to the bottom of the moving table 4; the positioning assembly 9 includes a first spacer bar 901 and a second spacer bar 902 respectively fixed on the top of the moving table 4, the first spacer bar 901 is located between the first short slide rail 5 and the second short slide rail 6, and the second spacer bar 902 is located on the other side of the second short slide rail 6; a positioning block 903 is fixed at one end of each of the first short slide rail 5 and the second short slide rail 6, and a laser distance sensor 904 is arranged above the positioning block 903 of the first short slide rail 5; a chute 905 is formed on one surface of the extruder body 1, the positioning blocks 903 are all slidably connected in the chute 905, and a mounting groove 906 is formed at the top of the chute 905, and the laser distance sensor 904 is fixed in the mounting groove 906.

[0026] The effect achieved by the entire embodiment 2 is that the T-shaped connecting block 13 is to ensure that the first mounting member 3 or the second mounting member 7 can be smoothly connected to the hydraulic cylinder 10 to perform corresponding activities while cooperating with the displacement function of the first mounting member 3 and the second mounting member 7; the mounting table 801 is fixed on one side of the extruder body 1, so that the electric push rod 803 can drive the moving table 4 to move accordingly through the connecting plate 804; the cooperation of the chute 905 and the positioning block 903 can limit the movement of the moving table 4, and the laser distance sensor 904 can respectively obtain the distance between it and the bottom of the chute 905 and the distance between it and the positioning block 903. When the detected value meets the distance from the positioning block 903, the electric push rod 803 can be stopped from working.

[0027] Working principle: When a new mold 15 needs to be replaced, the operator first installs the preheated new mold 15 into the empty second mounting member 7. After the new mold 15 is installed, the operator starts the hydraulic cylinder 10. The output end of the hydraulic cylinder 10 extends, pushing the first mounting member 3 to move outward on the long slide rail 2 until the first mounting member 3 slides to the outermost end of the moving table 4 and then stops. Subsequently, the electric push rod 803 is started. The output end of the electric push rod 803 extends, and it can drive the moving table 4 to move on the two guide rails 802 through the connecting plate 804. At this time, the positioning block 903 on the first spacer 901 gets out of the detection range of the laser distance sensor 904. At the same time, the T-shaped connecting block 13 on the first mounting member 3 disengages from the T-shaped groove 12 on the connecting sleeve 11. The positioning block 903 on the second spacer 902 moves in the chute 905 towards the laser distance sensor 904 until the laser distance sensor 904 detects the appearance of the positioning block 903 again. The laser distance sensor 904 feeds back this signal to the control device, and the control device can send a stop working instruction to the electric push rod 803. The electric push rod 803 stops. At this time, the positioning block 903 on the second spacer 902 is below the laser distance sensor 904, so the second short slide rail 6 is aligned with the long slide rail 2. At the same time, the T-shaped connecting block 13 on the second mounting member 7 slides and snaps into the T-shaped groove 12 on the connecting sleeve 11. Finally, the hydraulic cylinder 10 is started again to perform a reset operation, and its output end contracts. With the cooperation of the connecting sleeve 11 and the T-shaped connecting block 13, it can drive the second mounting member 7 installed with the new mold 15 to move to the corresponding position, thus completing the replacement of the mold 15;

[0028] The wiring diagram of the electric push rod 803, the laser distance sensor 904, and the hydraulic cylinder 10 in the present utility model with the control device of the extruder body 1 belongs to the common knowledge in the field. Its working principle is already known technology, and its model is selected according to actual use. Therefore, the control method and wiring arrangement of the electric push rod 803, the laser distance sensor 904, and the hydraulic cylinder 10 will not be explained in detail. In summary, the problems raised in the above background are solved.

[0029] The above description is only a preferred embodiment of the present utility model, and it is not a limitation to the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
