Detailed ways

Figure 2-7 shows the relevant explanatory diagrams of the present invention; a three-layer core-pulling slider mechanism, including a core-pulling cylinder 1, a cylinder mounting plate 2, a slider seat 3, a cylinder pull rod 4, a wedge pressing block 5, a A slider body 6, a second slider body 7, a first slider head insert 8, a second slider head insert 9, a central insert 10, a toggle pin 11, and a central inner core-pulling concave insert 12 , unlocking insert 13, lock cylinder spring 14, lock cylinder 15, slider separation spring 16, slider pull bar 17, as shown in Figure 2, Figure 3, and Figure 4.

The mechanism molding participating assembly includes a first slider head insert 8, a second slider head insert 9, a center insert 10, and a central core-pulling concave insert 12; the first slider head insert 8, the second slider insert The two slider head inserts 9 are installed on the second slider body 7 by screws; the central insert 10 is installed on the first slider body 6 by screws; On the second slider head insert 9; on the center insert 10, a toggle pin 11 is installed, and the toggle pin 11 connects the center insert 10 to the second center insert 10 through the sliding guide groove offered on the center inner core-pulling concave insert 12. The motion correlation of the slider head insert 9 is shown in Fig. 3, Fig. 5 and Fig. 6 .

The mechanism sliding assembly includes a first slider body 6, a second slider body 7, an unlocking insert 13, a lock cylinder spring 14, a lock cylinder 15, a slider separation spring 16, and a slider pull rod 17; the first slider body 6. The second slider body 7 is connected through the slider rod 17, and the lock cylinder spring 14 is set on the slider rod 17 and installed in the first slider body 6, which is used for core pulling to separate the first slider body 6 and The second slider body 7, the slider pull rod 17 is used to control the separation distance between the two; the unlocking insert 13 is installed on the first slider body 6 by screws, and its head is provided with an unlocking convex pressure head for The lock cylinder 15 is pressed down, and the lock cylinder 15 is installed on the slider seat 3, and a lock cylinder spring 14 is installed at its lower end, and the lock cylinder spring 14 is used to ensure the locking position reliability of the lock cylinder 15, and the main function of the lock cylinder 15 is to ensure When starting to pull the core, when the first slider body 6 and the second slider body 7 are separated, the second slider body 7 is locked in the original position; the bottom of the second slider body 7 is provided with a lock corresponding to the lock cylinder 15 Position groove; the inner side of the slider seat 3 is provided with a square groove for the first slider body 6 and the second slider body 7 to pull the core and reset on the slider seat 3, as shown in Figure 3, Figure 4, and Figure 7 .

The mechanism can realize three secondary core-pulling functions. The first core-pulling action is the synchronous core-pulling of the center insert 10 and the central inner core-pulling concave insert 12; the second core-pulling is the first sliding core-pulling action. Synchronous core pulling of the block head insert 8 and the second slider head insert 9.

The core-pulling power and support components of the mechanism include a core-pulling cylinder 1, a cylinder mounting plate 2, a slider seat 3, and a cylinder pull rod 4; On the slider seat 3, the core-pulling cylinder 1 drives the first slider body 6 and the second slider body 7 through the cylinder rod 4 to complete the core-pulling and reset actions.

In actual work, as shown in Figure 4, Figure 8, and Figure 9, the working principle of its movement is as follows:

1) The first core pulling After the injection molding of the mold is completed, after the mold is opened, the parting surface is opened, and the cavity surface has been demoulded; the wedge pressing block 5 loses the pressing effect on the first slider body 6, and the core pulling cylinder 1 moves Pull the first slider body 6 through the cylinder rod 4 to pull the core in the K direction shown in Figure 8. At this moment, the slider separation spring 16 bounces off, and the second slider body 7 is held against it to prevent it from moving, so as to ensure the first The slider body 6 slides first, and the first slider body 6 will slide out with the center insert 10 to the K1 direction of the distance S1 shown in Figure 8 and Figure 9 to pull the core. Synchronously, the toggle pin of the center insert 10 11 Force the central inner core-pulling concave insert 12 to move in the direction shown by K2 in Figure 9 through the sliding guide groove of the central inner core-pulling concave insert 12 to complete the inner core-pulling of the distance S2; After the completion, the first slider body 6 can pull the second slider body 7 out along the K direction, and the control is completed by the unlocking insert 13; therefore, the center round hole and the edge round hole of the product are completed for the first core pulling The core-pulling of the square hole on the inner wall, that is, the core-pulling of the two forming parts of the central insert 10 and the central inner core-pulling concave insert 12, as shown in Figure 4, Figure 8, and Figure 9, K, K1 The indicated direction is the same direction;

2) Second core-pulling At the end of the first core-pulling, after the unlocking insert 13 follows the first slider body 6 and moves along the K direction for a distance of S1, the concave part of the head of the lock core 15 overcomes the spring top of the lock core spring 14 The resistance is pressed down along the M direction, so that the lock cylinder 15 loses its locking and hindering effect on the second slider body 7, so that it can be pulled by the slider rod 17, and follow the first slider body 6 to pull the core along the K direction Movement, therefore, the second core-pulling completes the core-pulling of the round hole on the edge of the product, that is, drives the first slider head insert 8 and the second slider head insert 9 to complete the core-pulling of the edge round hole; the second time During the core pulling process, the lock cylinder 15 is always pressed down, as shown in Figure 8;

3) Reset When resetting, the core-pulling cylinder 1 moves, and the first slider body 6 is pushed back in the direction K shown in Figure 8 through the cylinder rod 4, and the first slider body 6 will be pushed back by the slider separation spring 16. The second slider body 7 pushes against and moves together. After the second slider body 7 is reset, the lock core 15 pops up to lock it, and the first slider body 6 will continue to press the slider separation spring 16 until the first slider body 7 is locked. The block body 6 is completely reset, and finally the mold is completely closed, and the wedging pressing block 5 completely compresses and locks the first slider body 6, waiting for the start of the next injection molding cycle.
