[0001] The utility model relates to the technical field of copper bar limiting structures, in particular to a copper bar limiting structure for an injection mold. Background Art

[0002] The positive and negative copper busbars are placed in the mold cavity. The old design and failure cases: the busbar is pushed directly below the busbar and has only one ejector pin. This solution easily leads to unbalanced ejection of the busbar during the actual injection molding process, which can easily cause the front to run to the front, and there is no way to limit whether the busbar is offset.

[0003] The existing device cannot ensure the balance of the copper busbar during the ejection process and solve the problem of the burr on the surface of the copper busbar. At the same time, it cannot effectively limit the displacement of the copper busbar during the filling process.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the above background technology, the existing technology has the problem that it cannot ensure that the copper busbar does not shake left and right and deviate from its position.

[0006] The utility model discloses a copper bar limiting structure for an injection mold, comprising a cylinder, wherein the output end of the cylinder is fixedly connected to a fixed block, the upper surface of the fixed block is provided with four placement grooves, the inner wall of each placement groove is plugged with a connecting block, the upper surface of each connecting block is fixedly connected to a ejector pin, a cover plate is provided above the fixed block, the upper surface of the cover plate is provided with four slide grooves, the inner wall of each slide groove is slidably connected to the corresponding ejector pin, the top of each ejector pin is provided with a threaded groove, the inner wall of each threaded groove is threadedly connected to a screw, a copper bar body is provided above the fixed block, and the outer surface of the copper bar body is clamped with the four ejector pins.

[0010] Furthermore, one end of one of the screw rods away from the fixing block is fixedly connected to a knob, and the outer surface of each of the screw rods is rotatably connected to the corresponding fixing groove.

[0011] Furthermore, one end of each screw rod close to each other is fixedly connected to a bevel gear, and the outer surface of each bevel gear is meshed with the adjacent bevel gear.

[0012] Furthermore, the outer surface of each screw is threadedly connected to a push block, and the side of each push block close to each other is fixedly connected to an insertion rod. The outer surface of each push block is slidingly connected to the corresponding fixed groove, and the outer surface of each insertion rod is plugged into the corresponding slot.

[0022] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0023] See also Figure 1 、 Figure 2 、 Figure 3 The present invention relates to a copper bar limiting structure for an injection mold, comprising a cylinder 1, wherein the output end of the cylinder 1 is fixedly connected to a fixed block 2. When the cylinder 1 is started, the fixed block 2 is driven to move in the direction of the output shaft of the cylinder 1. The upper surface of the fixed block 2 is provided with four placement grooves 12, and the inner wall of each placement groove 12 is plugged with a connecting block 10. The size and thickness of the connecting block 10 are the same as those of the corresponding placement groove 12. When the connecting block 10 is inserted into the corresponding placement groove 12, it can completely overlap with the fixed block 2. The upper surface of each connecting block 10 is fixedly connected with a ejector pin 4, and the ejector pin 4 is provided with four. A cover plate 3 is provided above the fixed block 2, and four slide grooves 11 are provided on the upper surface of the cover plate 3. By placing the four ejector pins 4, the slide grooves 11 on the cover plate 3 are inserted along the corresponding ejector pins 4 until the cover plate 3 contacts the fixed block 2. At this time, the cover plate 3 will squeeze and limit the connecting block 10, thereby limiting and fixing the four ejector pins 4.

[0024] In this embodiment, the inner wall of each slide groove 11 is slidably connected to the corresponding ejector pin 4, and a thread groove 9 is provided at the top of each ejector pin 4. A card slot is provided at the top of each ejector pin 4, and the opening direction of the card slot is toward the center between the four ejector pins 4. The inner wall of each thread groove 9 is threadedly connected with a screw 8. By inserting the screw 8 into the corresponding thread groove 9 and turning the screw 8, the screw 8 will enter the thread groove 9. A copper busbar body 5 is provided above the fixed block 2, and the outer surface of the copper busbar body 5 is carded with the four ejector pins 4. Specifically, by inserting the copper busbar body 5 into the card slot between the four ejector pins 4, the copper busbar body 5 can be installed on the four ejector pins 4.

[0025] In this embodiment, the outer surface of the copper busbar body 5 is fixedly installed with a first fixing bolt 6 and a second fixing bolt 7. The outer surface of each screw 8 is plugged into the copper busbar body 5. Specifically, after the copper busbar body 5 is installed, the screw 8 is inserted to fix the copper busbar body 5. The arrangement of the first fixing bolt 6 and the second fixing bolt 7 can connect and fix the copper busbar body 5 to the mold.

[0026] In this embodiment, a block 13 is fixedly connected to the bottom surface of the cover plate 3, and the four side surfaces of the block 13 are equal in length. Four slots 14 are provided on the outer surface of the block 13, and the four slots 14 are all arranged on the same horizontal plane. The outer surface of the block 13 is plugged into the fixed block 2. Specifically, when the cover plate 3 contacts the fixed block 2, the block 13 will be inserted into the fixed block 2.

[0027] like Figure 4 As shown, four fixing grooves 15 are opened inside the fixing block 2, and the four fixing grooves 15 are respectively arranged in four directions of the fixing block 2. A screw 16 is provided inside each fixing groove 15, and the screw 16 is arranged in the corresponding fixing groove 15. The four screws 16 are in a cross shape.

[0028] In this embodiment, one end of one of the screw rods 16 away from the fixed block 2 is fixedly connected to a knob 20. The setting of the knob 20 can facilitate the rotation of the screw rod 16 fixed thereto. The outer surface of each screw rod 16 is rotatably connected to the corresponding fixed groove 15, and the screw rod 16 will rotate in the corresponding fixed groove 15.

[0029] In this embodiment, each screw rod 16 is fixedly connected to a bevel gear 19 at one end close to each other, and the outer surface of each bevel gear 19 is engaged with the adjacent bevel gear 19. Specifically, the four screw rods 16 can rotate synchronously through the mutual engagement between the four bevel gears 19. When the knob 20 is rotated, the knob 20 will drive the four screw rods 16 to rotate simultaneously.

[0030] In this embodiment, the outer surface of each screw 16 is threadedly connected to a push block 17, and the rotation of the screw 16 will drive the corresponding push block 17 to move horizontally along the corresponding screw 16. At this time, the different settings of the thread direction and rotation direction of the four screws 16 make the push block 17 move in the opposite or reverse direction along the corresponding screw 16. Each push block 17 is fixedly connected to an insertion rod 18 on the side close to each other. The horizontal movement of the push block 17 will drive the corresponding insertion rod 18 to move horizontally. The outer surface of each push block 17 is slidably connected to the corresponding fixing groove 15, and the outer surface of each insertion rod 18 is plugged into the corresponding slot 14. Specifically, when the block 13 is inserted into the fixed block 2, the insertion rod 18 will be on the same central axis as the corresponding slot 14. At this time, the movement of the insertion rod 18 makes it plugged and fixed with the corresponding slot 14. Therefore, the four ejector pins 4 can be quickly fixed by fixing the cover plate 3.

[0031] The above is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
