[0002] A car headrest is a component installed above the back of a car seat to provide support for the head of drivers and passengers. During driving or riding in a car, the head needs proper support. A car headrest allows the head to maintain a natural and comfortable posture, reducing neck and head fatigue. Especially during long journeys, a suitable headrest can make drivers and passengers feel more relaxed.

[0003] Existing car headrests contain memory foam, which is manufactured using a special molding die. The foaming material of the memory foam is injected into the mold, and under the constraint of the mold, the foaming material expands into a special shape. However, the bottom and top molds of existing molding dies are connected by bolts, which makes this type of molding die less convenient to use and affects the production efficiency of memory foam. Therefore, we provide a headrest core component molding device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the fastening components of the molding mold used for processing memory foam inside car headrests are not convenient to use, and to provide a headrest core component molding device.

The embedding block is sleeved inside the bottom mold and slidably connected to the bottom mold. A limiting rod is provided on one side of the embedding block, and the limiting rod is fixedly connected to the embedding block and sleeved inside the bottom mold.

[0007] In a preferred embodiment, the limiting rod is slidably connected to the bottom mold, a rotating shaft is fixedly connected to a groove on the bottom mold, a rotating block is sleeved on the outer surface of the rotating shaft, the rotating block is rotatably connected to the rotating shaft, and the rotating block is fixedly connected to the top mold.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figures 1-4As shown, this utility model provides a technical solution: a headrest core component molding device, comprising: a molding mechanism 1, the molding mechanism 1 including a bottom mold 11, a top mold 12 provided on the top of the bottom mold 11, an extrusion block 13 sleeved inside the bottom mold 11, an arc surface block 14 sleeved inside the bottom mold 11 and the extrusion block 13, the arc surface block 14 being slidably connected to both the bottom mold 11 and the extrusion block 13, an embedding block 15 fixedly connected to one end of the arc surface block 14, a spring 17 provided on one side of the embedding block 15, and a connecting rod 18 fixedly connected to one end of the embedding block 15, the number of connecting rods 18 being two, an auxiliary mechanism 2 provided on one side of the bottom mold 11, the auxiliary mechanism 2 including a connecting block 21, a gear 22 provided inside the connecting block 21, the gear... One side of gear 22 is connected to a rack 23, and the other side of gear 22 is connected to a rack 24. Extrusion block 13 is slidably connected to bottom mold 11 and fixedly connected to top mold 12. Embedded block 15 is sleeved inside bottom mold 11 and slidably connected to bottom mold 11. One side of embedded block 15 is provided with a limiting rod 16, which is fixedly connected to embedded block 15 and sleeved inside bottom mold 11. The limiting rod 16 is slidably connected to bottom mold 11. A rotating shaft 19 is fixedly connected in a groove on bottom mold 11. A rotating block 101 is sleeved on the outer surface of rotating shaft 19 and rotatably connected to rotating shaft 19. The rotating block 101 is fixedly connected to top mold 12.

[0024] In this embodiment, by setting a bottom mold 11 and a top mold 12, both of which have cavities, the foaming material of the memory foam expands and fills the cavities of the bottom mold 11 and the top mold 12. Thus, the shape of the memory foam matches the cavities on the bottom mold 11 and the top mold 12, allowing the memory foam to fill the car headrest. An extrusion block 13 is also provided, which can compress and slide the curved block 14. Simultaneously, the extrusion block 13 has a feature that matches the curved block 14. The slot allows the arc-shaped block 14 to be tightly engaged with the extrusion block 13 after resetting, thus limiting the extrusion block 13 and achieving the purpose of tightly connecting the bottom mold 11 and the top mold 12. The embedded block 15 and the limiting rod 16 are provided and can be used together to prevent the spring 17 from twisting when compressed. The elastic force generated by the compression of the spring 17 can also be reset along a predetermined trajectory, ensuring that the arc-shaped block 14 can be tightly engaged inside the extrusion block 13.

[0025] Example 2

[0026] like Figures 1-4As shown, the connecting block 21 is fixedly connected to the bottom mold 11, the connecting rod 18 is sleeved inside the connecting block 21, and the connecting rod 18 is slidably connected to the connecting block 21. One of the connecting rods 18 is fixedly connected to the rack 1 23, and the other connecting rod 18 is fixedly connected to the rack 24. A limiting block 25 is fixedly connected to one side of the rack 1 23 and the rack 24. The limiting block 25 is sleeved inside the connecting block 21 and is slidably connected to the connecting block 21. A rotating rod 26 is sleeved inside the gear 22 and the connecting block 21. The rotating rod 26 is fixedly connected to the gear 22. A bearing 27 is sleeved at one end of the rotating rod 26 inside the connecting block 21. The bearing 27 is fixedly connected to the outer surface of the rotating rod 26 and the inner wall of the connecting block 21.

[0027] In this embodiment, by setting an auxiliary mechanism 2, which can be used in conjunction with the forming mechanism 1, the two embedded blocks 15 can move simultaneously in opposite directions. As a result, the two arc-shaped blocks 14 can simultaneously engage or disengage from the extrusion block 13, making it more convenient for the processing personnel to use the bottom mold 11 and the top mold 12. Furthermore, a gear 22 is set, and the gear 22 is meshed with both rack 1 23 and rack 24. Thus, when rack 1 23 moves, rack 24 can be driven simultaneously through the transmission of gear 22, allowing rack 24 to move in opposite or opposite directions to rack 1 23.

[0028] Working principle:

[0029] like Figures 1-4As shown, in use, a certain amount of memory foam material is first injected into the bottom mold 11. Then, the top mold 12 is connected to the bottom mold 11. When the top mold 12 is flipped, it drives the rotating block 101 to rotate around the rotating shaft 19. At the same time, the top mold 12 drives the extrusion block 13 to extrude the two arc-shaped blocks 14, allowing the arc-shaped blocks 14 to slide into the bottom mold 11. When the arc-shaped blocks 14 slide, they also drive the embedding block 15 and the limiting rod 16, allowing the embedding block 15 and the limiting rod 16 to compress the spring 17. The spring 17 generates elastic force. When the top mold 12 is completely attached to the bottom mold 11, the elastic force of the spring 17 is released instantly, and the embedding block 15 and the arc-shaped blocks 14 are automatically reset, allowing the arc-shaped blocks 14 to be tightly engaged in the extrusion block 13. When the memory foam... After the raw material has finished foaming, one of the connecting rods 18 can be pulled first. The connecting rod 18 drives one of the embedded blocks 15 to slide. The embedded block 15 can drive the arc block 14 to disengage from the extrusion block 13. At the same time, the connecting rod 18 can drive the rack 23 fixedly connected to it to slide. The rack 23 can mesh with the gear 22 under the guidance of the limiting block 25. The gear 22 can mesh with the rack 24 simultaneously under the cooperation of the rotating rod 26 and the bearing 27. Thus, the rack 24 and the rack 23 can slide in opposite directions at the same time. Then, the other embedded block 15 can also drive the arc block 14 to disengage from the extrusion block 13. Then, the processing personnel can easily release the engagement between the extrusion block 13 and the arc block 14, flip the top mold 12, and finally take out the memory foam inside the bottom mold 11.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
