[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0022] like Figure 3 As shown, the product extrusion strip assembly 2, which includes a plastic insert wrapping extrusion strip, comprises a top strip 201, a corner section 202, a vertical strip 203, a plastic insert 204, and a dividing strip 205.
[0023] A feeding and unloading mechanism for a plastic insert encapsulating an extruded strip, such as Figures 1 to 2 As shown, it includes a mold template 1, a product extrusion strip assembly 2, a slide rail 3, a bracket 4, a power source 5, a sliding connecting rod 6, a sliding key 7, a core base 8, a first core 9, a second core 10, a sensor bracket 11, a sensor 12, a sensor sensing block 13, an air connector 14, and a cylinder connecting rod 15.
[0024] The mold template 1 is equipped with the product extrusion strip assembly 2 to be processed. A slide rail 3 is fixed on one side of the mold template 1. A bracket 4 is fixed at the bottom of the slide rail 3. A power source 5 is installed on the bracket 4. The power source 5 is connected to a sliding link 6. A sliding key 7 is slidably installed on the slide rail 3. One end of the sliding key 7 is fixedly connected to the sliding link 6 and the other end is fixedly connected to a core base 8. A first core 9 and a second core 10 are installed on the core base 8. A sensor bracket 11 is provided on one side of the slide rail 3. Sensors 12 are installed at both ends of the sensor bracket 11. A sensor sensing block 13 is fixed on the side of the sliding key 7 facing the sensor bracket 11.
[0025] The power source 5 is a cylinder, which is equipped with an air passage connector 14. The piston rod of the cylinder is connected to a cylinder connecting rod 15, which is connected to a sliding connecting rod 6. Of course, the power source 5 does not necessarily have to be a cylinder; it can also be other feasible methods, such as a hydraulic cylinder or an electric motor.
[0026] The slide rail 3 has a slide track, and the sliding key 7 is slidably set in the slide track of the slide rail 3.
[0027] The sliding link 6 is fixed to the end of the sliding key 7 by bolts.
[0028] Both the first core 9 and the second core 10 have a boss positioning key at their bottom and are mounted on the core base 8 through the boss positioning key.
[0029] Specifically:
[0030] The power source 5 is fixed on the support 4, the support 4 is fixed on the bottom of the slide rail 3, the slide rail 3 is fixed on the mold plate 1; if the power source 5 is a cylinder, the air connection 14 is connected to the cylinder, the cylinder connecting rod 15 is connected to the cylinder, and the cylinder provides power.
[0031] The first core 9 and the second core 10 are both fixed on the core base 8, and there are boss positioning keys between the first core 9, the second core 10 and the core base 8, which can effectively ensure the positioning accuracy.
[0032] The sliding connecting rod 6 is fixed on the sliding key 7, the sliding key 7 is fixed on the core base 8, the sliding connecting rod 6 is connected with the cylinder connecting rod 15, and the power provided by the cylinder can make the sliding key 7 slide in the slide formed by the slide rail 3.
[0033] The sensor 12 is fixed on the sensor support 11, the sensor support 11 is fixed on the slide rail 3, and the sensor sensing block 13 is fixed on the sliding key 7. At the beginning and end positions of the cylinder action, two sensors 12 are arranged, and the sensor 12 obtains signals through the sensor sensing block 13 to detect the action position of the cylinder.
[0034] For the vertical strip 203 wrapped by the plastic insert 204, the action process of the mechanism is as follows:
[0035] The cylinder pushes from the starting position, and the first core 9, the second core 10 and the core base 8 retreat horizontally. After retreating to a certain distance, the cylinder reaches the end position and stops moving, as shown in Figure 1 .
[0036] The process of the cylinder returning from the end position to the starting position is the reverse process of the above process, as shown in Figure 2 , which will not be described here.
[0037] The first core 9, the second core 10 and the core base 8 retreat horizontally, and the direction of retreat should comprehensively consider the direction of the plastic insert core and the direction of the extruded strip. The distance of the retreat of the first core 9, the second core 10 and the core base 8 should ensure that the cutout at the front end of the vertical strip 203 is at least 5mm out of the plastic insert 204; then the plastic insert 204 is placed in the mold plate 1 of the corner connecting mold, and the vertical strip 203 is placed on the first core 9 and the second core 10 after being taken out; finally, the cylinder pushes the first core 9, the second core 10, the core base 8 and the vertical strip 203 back into the mold plate 1, the vertical strip 203 and the plastic insert 204 are loaded, and the plastic insert 204 wraps the vertical strip 203, and then other cores are returned to the original position, the divided strip 205 and the top strip 201 are placed, and all the loading is completed.
[0038] When unloading, all other cores in the corner connecting mold and the first core 9 and the second core 10 retreat, and the unloading is completed.
[0039] The unique automobile door and window sealing structure of the plastic insert wrapped extruded strip cannot be directly applied to the previous corner joint die mechanism. The utility model completes the innovation of the corner joint die from nothing to something by analyzing the characteristics of the automobile door and window sealing, successfully applies the automobile door and window sealing of the plastic insert wrapped extruded strip, achieves the production requirements, and takes into account the stability, efficiency and easy operability of the die.
[0040] The utility model inserts the vertical strip 203 into the plastic insert 204 to complete the feeding of the vertical strip 203.
[0041] The movement track of the profile plate is changed from horizontal movement to arc-shaped or other forms of movement, which should also be considered within the protection scope of the utility model.
[0042] The utility model has been described above in conjunction with the drawings, and obviously, the specific implementation of the utility model is not limited by the above-mentioned mode, and various improvements adopting the method concept and technical scheme of the utility model or direct application in other occasions without improvement are within the protection scope of the utility model.
