Abstract
Description
Technical Field
[0001] The invention relates to the field of automobile headrest production equipment technology, in particular to an integrated foaming production line for headrests. Background Art
[0002] At present, with the continuous advancement of my country's automobile industry technology and the increasing requirements for humanized automobile headrests, how to improve the appearance quality and comfort of products while effectively controlling production costs has become a common research topic for major automobile interior parts manufacturers; the previous production model was that automobile interior parts manufacturers first foamed the headrest sponge in a mold, and then covered and sewed a pillow cover on the outside of the headrest sponge. The headrests produced in this way sometimes have an insufficient appearance, and the cover and the foam sponge are not directly glued together. They are easy to fall off and wrinkle after a long period of use, and have a short service life. In addition, the product production process is complicated and the product cost is high.
[0003] In order to overcome the above problems, another mold is used. First, the pillowcase is placed in the mold and positioned, and then a funnel is manually inserted into the feed port of the pillowcase. Next, the funnel is injected with foaming material, and the foaming material enters the pillowcase along the funnel. After the injection is completed, the funnel is manually removed, and finally the mold is closed and heated. The foaming material expands due to the heat and fills the interior of the pillowcase.
[0004] The traditional method of using a funnel to receive materials has the following disadvantages:
[0005] 1. The funnel needs to be taken manually, which increases the labor intensity of workers and there is a risk of scalding workers.
[0006] 2. After the funnel is fed, the funnel will be covered with foaming material. If the foaming material on the funnel is not cleaned in time, the foaming material may block the funnel, which may cause insufficient feeding or leakage, resulting in defective products.
[0007] 3. Multiple molds require multiple funnels, which will increase costs. Summary of the invention

[0103] A second driving structure 54 is disposed on the mold structure 52; and
[0104] The opening member 55 is used to open the feed port of the headrest cover. When the foam material is injected into the headrest cover, the nozzle of the feeding robot 60 can be directly inserted from the feed port to inject the material. The opening member 55 is rotatably connected to the mold structure 52. The output end of the second driving structure 54 is connected to the opening member 55 and drives the opening member 55 to rotate on the mold structure 52.

The first driving structure 53 drives the first mold 521 to rotate, thereby adjusting the inclination angle of the entire mold structure 52, thereby adapting to different feeding angles, effectively avoiding the splashing of the injection plastic, and making the product cleaner.
[0108] The mold further includes a third driving structure 56, which is disposed on the first mold 521. The output end of the third driving structure 56 is connected to the second mold 522, and drives the second mold 522 to rotate on the first mold 521.

[0121] The working principle of this embodiment is described in detail as follows:
[0122] The first step is to start the production line, the driving mechanism 30 drives the turntable 20 to rotate, and drives the multiple foaming molds 50 to rotate;
[0123] In the second step, the fourth driving structure 67 drives the third mold 523 to open, and the third driving structure 56 drives the second mold 522 to open;
[0124] The third step is to manually place the semi-finished headrest 100 in the mold cavity 501 and clamp the connecting rod 101 of the headrest 100 in the clamping groove 591 for positioning;
[0125] Step 4: The second driving structure 54 drives the opening member 55 to rotate and insert the two opening arms 553 into the feed opening 102 of the headrest cover. Since the headrest cover is made of a soft and deformable material, when the two opening arms 553 are inserted into the feed opening 102 of the headrest cover, the feed opening 102 is deformed under the action of the two opening arms 553, so that the two opening arms 553 are smoothly inserted into the feed opening 102 and open the feed opening 102.
[0126] Step 5: The third driving structure 56 drives the second mold 522 to close the mold, thereby driving the semi-finished headrest 100 to be aligned;
[0127] Step 6: When the turntable 20 drives the foaming mold 50 to the side of the feeding robot 60, the feeding robot 60 will inject different foaming materials according to different types of foaming molds 50; the injection pipe 64 in the feeding robot 60 is inserted into the opened feed port 102 and injects the foaming material. After the injection of the foaming material is completed, the injection pipe 64 in the feeding robot 60 is moved out; then, the second driving structure 54 drives the opening member 55 to move out of the feed port 102;
[0128] Step 7: The fourth driving structure 57 drives the third mold 523 to close the mold, and the cover plate 58 moves with the third mold 523 and closes the avoidance opening 502, so that the entire mold structure 52 is molded;
[0129] In the eighth step, the heating device on the mold structure 52 generates heat, the foam material expands due to the heat, and fills the interior of the headrest cover, and at the same time, the feed port 102 is heated and fused;
[0130] The ninth step is to open the mold and take out the molded headrest 100.
[0131] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
