DETAILED DESCRIPTION

[0021] In order to further understand the characteristics, technical means and specific purposes and functions reached by the utility model, the utility model is described in further detail below in combination with the drawings and specific embodiments.

[0022] As Figures 1 to 6 shown, the utility model provides:

[0023] A pre-pressing device for processing injection molded automotive interior parts includes a processing base 1. A support plate 2 and a drive frame 7 are respectively provided on the top of the processing base 1. A trapezoidal block 12 is provided on the top of the drive frame 7. A first rotating rod 10 and a second rotating rod 19 are rotatably arranged inside the drive frame 7. One end of the first rotating rod 10 extends to the outside of the drive frame 7 and is provided with a connecting plate 5. A plurality of placement frames 6 are provided on the outer wall of the connecting plate 5. A movable frame 13 for placing injection molded parts is movably arranged inside the placement frame 6. A top rod 15 is provided at the bottom of the movable frame 13. One end of the top rod 15 extends to the outside of the placement frame 6 and is provided with a roller 16. A spring 14 is sleeved on the outside of the top rod 15. One end of the spring 14 is connected to the top of the roller 16, and the other end of the spring 14 is connected to the bottom of the placement frame 6. An extrusion assembly for extruding injection molded parts is provided on the top of the support plate 2.

[0024] The roller 16 contacts the trapezoidal block 12, and under the action of the inclined surface of the trapezoidal block 12, the top rod 15 will slowly move upward. At the same time, the movable frame 13 and the injection molded part inside the placement frame 6 will also move upward. When the movable frame 13 and the injection molded part move upward to a certain distance, they will come into contact with the downward moving extrusion plate 24. Thus, the extrusion plate 24 can be used to pre-press the injection molded part. Through the intermittent rotation of the connecting plate 5, the operator does not need to perform any other operations when the injection molded part is pre-pressed. They only need to wait for the pre-pressing of the injection molded part to be completed. While waiting, the operator can relieve the fatigue of the work and reduce the workload of the operator.

[0025] like Figure 5 As shown, the extrusion assembly includes a motor 3 mounted on the top of the support plate 2. The output shaft of the motor 3 is connected to a drive rod 4 via a coupling. A second bevel gear 23 is mounted on the outside of the drive rod 4. A half gear 21 is mounted on one end of the drive rod 4. A gear ring 20 is meshed with the outside of the half gear 21. An extrusion plate 24 for extruding the injection molded part is mounted on the bottom of the gear ring 20.

[0026] The motor 3 drives the drive rod 4 to rotate, and at the same time, the half gear 21 at one end of the drive rod 4 also rotates. The half gear 21 works with the gear ring 20 to drive the gear ring 20 to move downward, which in turn drives the extrusion plate 24 at the bottom of the gear ring 20 to move downward, thereby performing pre-pressing work on the injection molded part.

[0027] like Figure 4 As shown, the first rotating rod 10 has an irregularly shaped block 9 on its outside, and the top of the second rotating rod 19 has a chuck 11 and a contact rod 17 that work in conjunction with the irregularly shaped block 9.

[0028] The first rotating rod 10 and the connecting plate 5 can be driven to rotate intermittently by the abutment rod 17 and chuck 11 at the bottom of the second rotating rod 19, and the placement frame 6 outside the connecting plate 5 will also rotate intermittently.

[0029] As Figure 5 shown, the top of the processing seat 1 is also rotationally provided with a linkage rod 8, one end of the linkage rod 8 penetrates through the support plate 2 and is provided with a first bevel gear 22 which is meshingly connected with the second bevel gear 23.

[0030] The first bevel gear 22 is rotated by the second bevel gear 23, thereby driving the linkage rod 8 to rotate.

[0031] As Figure 4 shown, the second rotating rod 19 and the outside of the linkage rod 8 are both provided with synchronous wheels, and the two synchronous wheels are drivingly connected through a synchronous belt 18.

[0032] The synchronous wheels on the outside of the linkage rod 8 and the synchronous belt 18 can drive the second rotating rod 19 to rotate, further driving the connecting disc 5 to rotate intermittently.

[0033] As Figure 5 shown, the top of the support plate 2 is provided with a limiting frame 25 for limiting the tooth ring 20.

[0034] The limiting frame 25 can prevent the tooth ring 20 from deviating in position when moving.

[0035] Working principle: when the injection molded part needs to be pre-pressed, first place the injection molded part in the different movable frames 13 in turn, then start the motor 3 to drive the driving rod 4 and the second bevel gear 23 to rotate, at the same time, the half gear 21 at one end of the driving rod 4 will also rotate, the half gear 21 works with the tooth ring 20 to drive the tooth ring 20 to move downward, further driving the extrusion plate 24 at the bottom of the tooth ring 20 to move downward, the first bevel gear 22 works with the second bevel gear 23 to drive the linkage rod 8 to rotate, the synchronous wheels on the outside of the linkage rod 8 and the synchronous belt 18 can drive the second rotating rod 19 to rotate, then the abutting rod 17 at the bottom of the second rotating rod 19 and the chuck 11 can drive the first rotating rod 10 and the connecting disc 5 to rotate intermittently, and the placement frame 6 outside the connecting disc 5 will also rotate intermittently, when the placement frame 6 rotates, it will drive the roller 16 to contact the trapezoidal block 12, under the action of the inclined surface of the trapezoidal block 12, the top rod 15 will slowly move upward, at the same time, the movable frame 13 inside the placement frame 6 and the injection molded part will also move upward, when the movable frame 13 and the injection molded part move upward to a certain distance, they will contact the downward moving extrusion plate 24 and be pressed downward by the extrusion plate 24, thereby the extrusion plate 24 can pre-press the injection molded part, through the intermittent rotation of the connecting disc 5, the worker does not need to perform other operations when pre-pressing the injection molded part, only needs to wait for the pre-pressing of the injection molded part to be completed, and the worker can relieve fatigue when working and reduce the labor burden of the worker.
