Description

TECHNICAL FIELD

[0001] The application relates to the technical field of foam processing, in particular to a foaming device for a vehicle roof part. BACKGROUND

[0002] PU foam blocks, also known as polyurethane PU foam blocks, are polyurethane materials formed by the reaction of polyol and isocyanate. The material is made by injecting into a mold and has the characteristics of porosity, low density and high strength. PU foam blocks are widely used in the automotive industry, furniture manufacturing and other fields.

[0003] At present, the mold for making PU foam blocks generally includes a box mold, and an inner mold plate is fixedly connected in the box mold. The material is injected into the box mold for foaming, and finally a cuboid-shaped PU foam block is formed.

[0004] However, in the field of automobile industry, since some car roofs are provided with sunroofs or viewing glasses, the middle part of the PU foam block needs to be hollowed out and cut according to the position of the sunroof or viewing glass. This way not only causes waste of raw materials, but also the cut PU foam block needs to be incinerated in a designated treatment pool, which additionally increases the production and processing cost. CONTENT OF THE INVENTION

[0005] In order to reduce material waste and reduce processing cost, the application provides a foaming device for a vehicle roof part.

[0006] The foaming device for a vehicle roof part provided by the application adopts the following technical scheme:

[0007] The foaming device for a vehicle roof part comprises an outer frame body, an outer mold plate and a bottom plate are arranged on the inner side of the outer frame body, an inner frame body is arranged in the middle of the top surface of the bottom plate, an inner mold plate is arranged on the outer side of the inner frame body, the inner mold plate, the bottom plate and the outer mold plate form a foaming space, and the inner frame body is provided with a fixing assembly for connecting and fixing with the bottom plate.

[0008] By adopting the above technical scheme, when the foaming device is needed, the inner frame body is first fixed on the bottom plate through the fixing assembly, at this time the inner mold plate, the bottom plate and the outer mold plate form a foaming space, then the raw material is poured into the foaming space for foaming and forming a foaming material. Since the foaming space encloses the inner frame body, when demolding, the middle of the foaming material naturally forms a hollow shape, avoiding cutting after overall forming and causing material waste, and being conducive to reducing processing cost.

[0009] Optionally, the fixing component includes a first bolt, and a fixing lug is provided on the inner side of the inner frame. The first bolt passes through the fixing lug and is threadedly connected to the base plate.

[0010] By adopting the above technical solution, when it is necessary to fix the inner frame, the inner frame is first placed in the center on the base plate, and then the first bolt is inserted through the fixing lug and the first bolt is tightened at the same time. At this time, the inner frame is fixed on the base plate, which helps to improve the convenience of disassembling and assembling the inner frame.

[0011] Optionally, a mold is provided on the inner side of the outer template, and the outer frame is provided with a disassembly and assembly component for fixing the mold.

[0012] By adopting the above technical solution, the mold is fixed in the foaming space by disassembling and assembling components. The mold is conducive to changing the shape of the foaming space, thereby changing the shape of the foaming material, which is conducive to meeting the diversity of production and processing needs.

[0013] Optionally, the mold includes a telescopic crossbeam, with side frames hinged at both ends of the telescopic crossbeam. A mold plate is provided on the inner side of both the telescopic crossbeam and the side frames. The side frames are detachably connected to the outer frame via the disassembly assembly.

[0014] By adopting the above technical solution, when it is necessary to change the shape of the mold, the side frame is adjusted by swinging and the telescopic cross frame is adjusted by telescopic adjustment, and then the mold of the current shape is fixed by disassembling and assembling the components, so as to finally obtain foamed materials of different shapes, which is conducive to improving the diversity of foamed material production and processing.

[0015] Optionally, the disassembly assembly includes a second bolt, a connecting rod is provided at one end of the side frame, a slider is slidably and rotatably provided on the bottom surface of the connecting rod, a sliding groove is provided on the top surface of the outer frame, the slider is slidably connected to the sliding groove, an adjustment groove is provided on the outer side of the outer frame, the adjustment groove is connected to the sliding groove, the second bolt passes through the adjustment groove and the slider in sequence, the second bolt is threadedly connected to the slider, and the connecting rod is provided with a fixing member for fixing the slider.

[0016] By adopting the above technical solution, the shape of the mold is adjusted by swinging the side frame. During the swinging process of the side frame, the side frame drives the slider to swing through the connecting rod. At this time, the slider slides and rotates on the bottom surface of the connecting rod. When it is necessary to fix the mold, the slider and the connecting rod are first fixed relative to each other by the fixing component. Then, the second bolt is passed through the adjustment groove and the slider in sequence. At this time, the slider is fixed in the groove and the mold is fixed in the current shape, which helps to improve the stability of the mold fixing.

[0017] Optionally, the fixing component is a third bolt, and a fixing groove is provided on the top surface of the connecting rod. The third bolt passes through the fixing groove and is threadedly connected to the top surface of the slider.

[0018] By adopting the above technical solution, the third bolt passes through the fixing groove and is threadedly connected to the slider. Under the action of friction, the slider and the connecting rod are relatively fixed, which helps to improve the stability of the slider fixed to the bottom surface of the connecting rod.

[0019] Optionally, a crossbar is provided on the inner side of the inner frame, and a lifting ring is provided on the top surface of the crossbar.

[0020] By adopting the above technical solution, after the contact fixing component is locked, the inner frame is lifted by the lifting ring, which helps to improve the convenience of demolding the inner frame.

[0021] Optionally, the inner wall of the outer template, the outer wall of the inner template, the top surface of the bottom plate, and the inner wall of the profile are all provided with diaphragms.

[0022] By adopting the above technical solution, the diaphragm helps to prevent the foaming material from adhering to the outer template, inner template, bottom plate, and mold plate, thereby improving the convenience of demolding.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] When a foaming device is required, the inner frame is first fixed to the base plate by the fixing components. At this time, the inner template, the base plate and the outer template form a foaming space. Then, the raw material is poured into the foaming space to foam and form foam material. Since the foaming space surrounds the inner frame, the foam material naturally forms a hollow shape in the middle after demolding, avoiding the waste of material caused by cutting after the whole molding and reducing processing costs.

[0031] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0032] Example:

[0033] See Figure 1 and Figure 2 A foaming device for automotive headliner components includes an outer frame 1. An outer template 2 is bolted to the inner side of the outer frame 1, and a base plate 3 is threaded to the inner bottom wall of the outer frame 1. An inner frame 4 is mounted on the top surface of the base plate 3, with the inner frame 4 centered on the top surface of the base plate 3. An inner template 5 is bolted to the outer side of the inner frame 4. The inner template 5, the base plate 3, and the outer template 2 enclose a foaming space 6 for the foaming material. A fixing assembly is also installed on the inner frame 4 to fix the inner frame 4 to the top surface of the base plate 3.

[0034] In this embodiment, the foaming material is specifically PU cotton. Foaming material has good heat insulation, sound absorption and sound insulation properties, and is widely used in the automotive industry and home life.

[0035] The foaming device serves as a mold for producing and processing foamed materials. When the foaming device is needed, the inner frame 4 is fixed to the top surface of the base plate 3 via a fixing component. At this time, the inner template 5, the base plate 3, and the outer template 2 form the foaming space 6 for the foamed material. Since the foaming space 6 encloses the inner frame 4, the foamed material formed after the inner frame 4 is demolded has a hollow center, saving the subsequent cutting steps.

[0036] For details, see Figure 2 The fixing component includes a first bolt 7. A fixing lug 8 is fixedly connected to the inner side of the inner frame 4. Multiple fixing lugs 8 are provided, and each fixing lug 8 abuts against the top surface of the base plate 3. The number of first bolts 7 is the same as the number of fixing lugs 8. The fixing end of the first bolt 7 passes through the fixing lug 8, and the fixing end of the first bolt 7 is threadedly connected to the base plate 3.

[0037] When it is necessary to fix the inner frame 4, first place the inner frame 4 in the center on the top surface of the base plate 3, then pass the fixing end of the first bolt 7 through the fixing lug 8 and tighten the first bolt 7 with threads. At this time, the inner frame 4 fixes the top surface of the base plate 3.

[0038] See Figures 2-5 Since different needs require different shapes of foaming material, the desired shape of foaming material can be obtained by changing the shape of the foaming space 6. For this purpose, a mold 9 is installed on the inner side of the outer template 2. The mold 9 includes a telescopic crossbeam 10. Side frames 11 are respectively hinged to both ends of the telescopic crossbeam 10. A mold plate 12 is fixedly connected to the inner side of both the side frames 11 and the telescopic crossbeam 10.

[0039] In this embodiment, the mold frame is trapezoidal in shape, and the outer frame 1 is also equipped with a disassembly and assembly assembly, which is used to fix the mold 9. The disassembly and assembly assembly includes a second bolt 13. A connecting rod 14 is fixedly connected to one end of the side frame 11 away from the telescopic crossbar 10. A slider 15 is slidably and rotatably mounted on the bottom surface of the connecting rod 14. A sliding groove 16 is provided on the top surface of the outer frame 1, and the slider 15 is slidably connected in the sliding groove 16. An adjustment groove 17 is provided on the outer side of the outer frame 1. The adjustment groove 17 is connected to the sliding groove 16. The fixing end of the second bolt 13 passes through the adjustment groove 17, and the fixing end of the second bolt 13 is threadedly connected to the slider 15.

[0040] In addition, to improve the stability of the slider 15 sliding and rotating on the bottom surface of the connecting rod 14, a guide groove 18 is provided on the bottom surface of the connecting rod 14, and a guide block 19 is fixedly connected to the top surface of the slider 15. The guide block 19 is slidably and rotatably installed in the guide groove 18.

[0041] Meanwhile, to facilitate fixing the slider 15 to the bottom surface of the connecting rod 14, the connecting rod 14 is equipped with a fixing component, which is a third bolt 20. A fixing groove 21 is provided on the top surface of the connecting rod 14, which is connected to the guide groove 18. The fixing end of the third bolt 20 passes through the fixing groove 21 and is threadedly connected to the top surface of the guide block 19.

[0042] When the shape of the mold 9 needs to be adjusted, the angle of the side frame 11 is adjusted according to the actual swing, or the length of the telescopic cross frame 10 is adjusted by stretching. At this time, the connecting rod 14 always abuts against the top surface of the outer frame 1, and the slider 15 slides in the slide groove 16. When the shape of the mold 9 is determined, the second bolt 13 and the third bolt 20 are tightened respectively, so that the slider 15 is fixed to the bottom surface of the connecting rod 14 and the slider 15 is fixed in the slide groove 16, thus completing the adjustment and fixing of the mold 9.

[0043] See Figure 2 To facilitate the subsequent removal of the inner frame 4 from the outer frame 1, a crossbar 22 is fixedly connected to the inner side of the inner frame 4, and a lifting ring 23 is fixedly connected to the top surface of the crossbar 22. The lifting ring 23 is used to lift the inner frame 4, improving the convenience of placing and removing the inner frame 4.

[0044] It is worth mentioning that, see Figure 1 and Figure 2A diaphragm 24 is attached to the inner wall of the outer template 2, the outer wall of the inner template 5, the top surface of the base plate 3, and the inner wall of the mold plate 12. The diaphragm 24 is a high-temperature resistant film. Under the action of the diaphragm 24, it helps to prevent the foaming material from adhering to the outer template 2, the inner template 5, the base plate 3, and the mold plate 12, thereby improving the convenience of demolding.

[0045] It should be noted that the outer template 2, inner template 5, base plate 3, and profile plate 12 are all made of wood.

[0046] Working principle of a foaming device for automotive headliner components:

[0047] When the foaming device is required, the inner frame 4 is first placed in the center on the top surface of the base plate 3 by means of the lifting ring 23. Then, the fixing end of the first bolt 7 is passed through the fixing lug 8 and the first bolt 7 is tightened by thread. At this time, the inner frame 4 is fixed to the top surface of the base plate 3.

[0048] If it is necessary to obtain the desired shape of foam material by changing the shape of the foaming space 6, the angle of the side frame 11 is adjusted according to the actual swing, or the length of the telescopic cross frame 10 is stretched and adjusted. At this time, the connecting rod 14 always abuts against the top surface of the outer frame 1, and the slider 15 slides in the groove 16. When the shape of the mold 9 is determined, the second bolt 13 and the third bolt 20 are tightened respectively, so that the slider 15 is fixed to the bottom surface of the connecting rod 14 and the slider 15 is fixed in the groove 16, thus completing the adjustment and fixing of the mold 9.

[0049] Finally, the raw materials needed to make the foaming material are injected into the foaming space 6 to foam, and finally the foaming material is formed.

[0050] In summary, since the foaming space 6 encloses the inner frame 4, the foam material naturally forms a hollow shape in the middle after demolding, avoiding the waste of material caused by cutting after overall molding, and at the same time helping to reduce processing costs.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
