[0003] Bumpers generally use an external parting method, but the front and rear mold parting positions are usually located at the boundary of the appearance surface. It is easy to leave flash or parting marks in the bumper mold, affecting the overall effect of the appearance surface, and requiring secondary processes such as polishing and painting, which increases cost input and consumption. In order to achieve one-time molding of injection molding and ensure that there are no defects in the appearance, we use an internal parting mold parting structure to move the parting position away from the visible area of ​​the appearance surface or to the inner non-appearance surface, so as to maintain the integrity of the appearance surface in the mold, and the appearance quality is better than external parting.

[0004] The cavity of the external parting bumper mold wraps part of the appearance R fillet in the cavity, and the other part of the fillet is formed on the core side, so there is a parting line at the fillet boundary. The cavity of the internal parting bumper mold wraps the entire appearance fillet in the cavity, and there is no parting line at the fillet.

In the process of opening the front mold 1, the deformation force of the nitrogen spring 35 drives the second ejector plate 24 and the first ejector plate 23 to move, the first ejector plate 23 drives the first buckle machine 32 to move, and the second ejector plate 24 drives After the locking piece 34 moves to allow the large cap top block 27, the inclined top block 25 and the straight top block 26 to move to the first stroke, the locking piece 34 disengages from the second ejector plate 24, and the front mold 1 can also drive the hook 31 to continue to move in the direction of mold opening, the hook 31 drives the first buckle machine 32 to move, the first buckle machine 32 drives the first ejector plate 23 to move, and the first ejector plate 23 drives the inclined top block 25 and the straight ejector block 26 to move to the second stroke, the first buckle machine 32 disengages from the hook 31, and the inclined ejector block 25 and the straight ejector block 26 push the product into the cavity of the front mold 1. By arranging the nitrogen spring 35, the first buckle machine 32 and the second buckle machine 33, the large cap top block 27, the inclined ejector block 25 and the straight ejector block 26 can move when the front mold 1 is opened, so that the large cap top block 27 and the inclined ejector block 25 can be separated from the buckling position of the product, thereby realizing that the front and rear molds 2 can be opened at the same time to meet the needs of customers.

[0046] It should be noted that the front mold 1 needs to be driven by an external power source during the mold opening process. The front mold 1 has a cavity, and the cavity cooperates with the large cap top block 27, the inclined top block 25 and the straight top block 26 to form a product after injection molding.

[0047] It is worth noting that when the front mold 1 is driven by an external power source to open the mold, due to the deformation force of the nitrogen spring 35, the first ejector plate 23 and the second ejector plate 24 are opened simultaneously with the front mold 1, thereby avoiding the buckle position of the product.

[0048] In this embodiment, the mold further includes a limiting column 4, which is mounted on the bottom plate 21. After the second ejector plate 24 moves to the first stroke, the limiting column 4 limits the movement of the second ejector plate 24. Specifically, during the process of opening the front mold 1, the deformation force of the nitrogen spring 35 drives the second ejector plate 24 and the first ejector plate 23 to move, the first ejector plate 23 drives the first locking machine 32 to move, and the second ejector plate 24 drives the locking member 34 to move, so that after the large cap ejector block 27, the inclined ejector block 25 and the straight ejector block 26 move to the first stroke, the locking member 34 is disengaged from the second ejector plate 24, and the distance of the first stroke can be 120 mm. After moving to the first stroke, the limiting column 4 limits the second ejector plate 24, thereby preventing the second ejector plate 24 from continuing to move. At this time, the locking member 34 is disengaged from the second ejector plate 24, and the first ejector plate 23 is not restricted by the second ejector plate 24 and can continue to move.

[0049] like Figures 1 to 6 As shown, the locking member 34 includes a mounting block 341, a locking block 342, a first elastic member 343 and a connecting block 344. The second latch 33 includes a locking segment 331 and a disengagement segment 332 connected to the locking segment 331. The mounting block 341 is mounted on the first ejector plate 23. The mounting block 341 is provided with a placement cavity 3411, and a mounting cavity 3412 and a through hole 3413 communicated with the placement cavity 3411. The connecting block 344 passes through the first ejector plate 23 and is connected to the second ejector plate 24. The connecting block 344 is provided with a locking groove 3441. The first elastic member 343 is installed in the mounting cavity 3412 and is connected to the locking block 342. The deformation force of the first elastic member 343 drives the locking block 342 to extend from the through hole 3413 into the locking groove 3441. The locking block 342 is provided with a through groove 3421, and the locking segment 331 is arranged in the through groove 3421. Specifically, the first elastic member 343 may be a spring.

[0050] When the nitrogen spring 35 drives the second ejector plate 24 and the first ejector plate 23 to move, the locking block 342 moves from the locking section 331 to the disengagement section 332. The disengagement section 332 is arranged in the through groove 3421 and abuts against the groove wall of the through groove 3421. The locking block 342 and the mounting block 341 squeeze the first elastic member 343 to make the locking block 342 disengage from the locking groove 3441. Specifically, when the nitrogen spring 35 drives the second ejector plate 24 and the first ejector plate 23 to move, the second ejector plate 24 drives the connecting block 344 to move. At the same time, the first ejector plate 23 drives the mounting block 341, the locking block 342 and the first elastic member 343 to move. When the locking block 342 moves from the locking section 331 to the disengagement section 332, the disengagement section 332 abuts against the groove wall of the through groove 3421, which drives the locking block 342 to move to one side. The locking block 342 and the mounting block 341 squeeze the first elastic member 343, so that the locking block 342 disengages from the locking groove 3441, thereby allowing the locking member 34 to disengage from the second ejector plate 24.

[0051] In this embodiment, the first ejector plate 23 is provided with a first avoidance groove 231, which is used to avoid the locking section 331, and the second ejector plate 24 is provided with a second avoidance groove 241, which is used to avoid the disengagement section 332. By providing the first avoidance groove 231 and the second avoidance groove 241, the movement process of the first ejector plate 23 and the second ejector plate 24 is prevented from interfering with the second locking machine 33.

[0052] Furthermore, the mold further includes a travel switch 5 and a square iron 6, the body 22 is mounted on the bottom plate 21 through the square iron 6, the travel switch 5 is mounted on the square iron 6, and is used to limit the travel of the first ejector plate 23. By setting the travel switch 5, the moving travel of the first ejector plate 23 can be limited. The second travel of the first ejector plate 23 can be 50 mm. At this time, the first ejector plate 23 drives the inclined ejector block 25 and the straight ejector block 26 to push the product into the cavity of the front mold 1, so that the product stays in the front mold 1 for easy removal.

[0053] During implementation, after the mold is opened, the product remains in the cavity of the front mold 1. After the suction cup cylinder moves the product to the side away from the front mold 1 and the rear mold 2, the robot takes the product out of the cavity of the front mold 1. This avoids direct removal and damage to the product due to undercut.

[0054] In one embodiment, if Figures 1 to 5 As shown, the mold opening assembly 3 also includes a limit block 36 and a roller 37. The limit block 36 is installed on the main body 22. The limit block 36 is provided with a sliding groove 361 and a disengagement groove 362 connected to the sliding groove 361. The roller 37 is rotatably connected to the first latch machine 32, and the first latch machine 32 is rotatably connected to the first ejector plate 23.

[0055] When the hook 31 drives the first hook 32 to move, the first hook 32 drives the roller 37 to move from the sliding groove 361 to the disengaging groove 362, the groove wall of the disengaging groove 362 abuts the roller 37, and the roller 37 drives the first hook 32 to deflect away from the hook 31, so that the first hook 32 is disengaged from the hook 31. Specifically, when the hook 31 drives the first hook 32 to move, the first hook 32 drives the roller 37 to move from the sliding groove 361 to the disengaging groove 362, the groove wall of the disengaging groove 362 abuts the roller 37, so that the roller 37 drives the first hook 32 to deflect away from the hook 31, so that the first hook 32 is disengaged from the hook 31, and then the front mold 1 continues to open the mold, completing the complete separation of the front and rear molds 2.

[0056] In one embodiment, if Figure 7 and Figure 8 As shown, the hook 31 includes a hook body 311 and a second elastic member 312. The front mold 1 is provided with a connecting groove 11. The hook body 311 is slidably connected in the connecting groove 11. The second elastic member 312 is arranged in the connecting groove 11 and elastically connected to the groove wall of the connecting groove 11 and the hook body 311. Specifically, the second elastic member 312 can be a spring. When the first latch 32 accidentally collides with the hook 31, the hook body 311 can retract into the connecting groove 11. At this time, the hook body 311 and the groove wall of the connecting groove 11 squeeze the second elastic member 312, so that the second elastic member 312 undergoes elastic deformation, thereby buffering the hook body 311 and avoiding the hook body 311 and the first latch 32 from being damaged by a head-on collision.

[0057] In one embodiment, if Figure 1 and Figure 2 As shown, the mold further includes a driving member 7, which is detachably connected to the first ejector plate 23 and is used to drive the first ejector plate 23 to move. Specifically, the driving member 7 can be an oil cylinder.

[0058] When the first latch 32 and the draw hook 31 are not used, the draw hook 31 is removed from the front mold 1, the oil cylinder is connected to the first ejector plate 23, and the deformation force of the nitrogen spring 35 drives the second ejector plate 24 and the first ejector plate 23 to move. The first ejector plate 23 drives the first latch 32 to move, and the second ejector plate 24 drives the locking piece 34 to move, so that the large cap ejector block 27, the inclined ejector block 25 and the straight ejector block 26 move to the first stroke, and the locking piece 34 disengages from the second ejector plate 24, and the oil cylinder drives the first ejector plate 23 to move. After the first ejector plate 23 drives the inclined ejector block 25 and the straight ejector block 26 to move to the second stroke, the first latch 32 disengages from the draw hook 31, and the inclined ejector block 25 and the straight ejector block 26 push the product into the cavity of the front mold 1.
