[0028] like Figure 1 and Figure 2 As shown, a glue feeding structure for high gloss products includes:

[0029] The glue feeding component 10 is used to output the liquid glue;

[0030] The molding assembly 20 includes a first molding member 21 and a second molding member that forms a sleeve structure with the first molding member 21, and a molding space is provided between the first molding member 21 and the second molding member;

[0031] The molding component 20 further includes a sealing member 22 disposed at one end of the first molding member 21 close to the glue feeding component 10 ; the sealing member 22 is recessed in a direction away from the glue feeding component 10 to form a buffer groove.

[0032] In this embodiment, a sealing member is provided at one end of the first molding member 21 close to the glue feeding component 10, and a buffer groove is formed by recessing in the direction away from the glue feeding component 10. The sealing member 22 is used to seal the open part of the product for glue feeding, which can improve the molding yield and molding cycle, and solve the appearance defects caused by the glue feeding problem of the product. At the same time, the buffer groove is used to buffer the liquid colloid, which can improve the glue flow molding, so that the liquid colloid enters the molding space evenly, avoiding defects such as air marks and punching marks on the product, thereby forming a high-gloss product. The product structure diagram is shown as follows Figure 3 shown.

[0033] Specifically, by utilizing the position design of the buffer groove and the glue feeding component, the liquid colloid first passes through the buffer groove and then is indirectly filled into the molding space, thereby avoiding the appearance problems caused by direct glue feeding. The glue feeding structure is used to produce high-gloss products, which can improve the production yield and facilitate molding. At the same time, the sealing member with a buffer groove structure is used to improve the glue feeding molding, and it is also convenient to remove the glue-added part during the later CNC machining.

[0034] In some embodiments, the glue feeding component 10 is a hot runner needle valve glue feeding component.

[0035] In some embodiments, the glue feeding component 10 and the sealing component 22 are located on the same central axis. By arranging the glue feeding component 10 and the sealing component 22 on the same central axis, the liquid colloid output by the glue feeding component can fall into the center position of the sealing component, and then flow into the molding space in the form of diffused glue under the action of accumulation to prepare a high-gloss product.

[0036] In some embodiments, the glue feeding component 10 and the sealing member 22 are spaced apart to ensure smooth glue discharge from the glue feeding component.

[0037] In some embodiments, the distance between the end point of the glue inlet component 10 close to the sealing member 22 and the plane where the edge of the buffer groove is located is 0.7mm-1mm, so as to prevent the glue on the surface of the buffer groove from adhering to the glue inlet component after solidification and damaging the glue inlet component.

[0038] In a preferred embodiment, the distance between the end point of the glue feeding component close to the sealing member and the plane where the edge of the buffer groove is located is 0.8 mm.

[0039] In some embodiments, the depth of the buffer groove is 3.5mm-3.7mm, so that after the glue inlet component injects glue into the buffer groove, it flows into the molding space in the form of diffused glue under the action of accumulation, which can improve the yield of the product and facilitate molding and injection molding.

[0040] In a preferred embodiment, the depth of the buffer groove is 3.6 mm.

[0041] In some embodiments, a storage tank 23 is provided at the bottom of the buffer tank for storing glue with a lower temperature when the glue injection assembly 10 is first injected. Subsequently, the glue reaching the standard temperature flows into the molding space in the form of diffusion.

[0042] In some embodiments, the glue feeding component 10 includes a glue injection component 11 and a heating component 12, and the heating component 12 is sleeved on one end of the glue injection component 11 close to the sealing component 22. The hot runner needle valve glue feeding process is realized by utilizing the heating component sleeved on the glue injection component 11.

[0043] In some embodiments, one end of the glue injection member 11 close to the sealing member 22 is a glue outlet 13, and the diameter of the glue outlet 13 is 3mm-3.2mm, so as to achieve uniform glue discharge and avoid blockage of the glue outlet.

[0044] In a preferred embodiment, the diameter of the glue outlet 13 is 3.2 mm.

[0045] In some embodiments, the width of the molding space is but not limited to 1.8 mm-2.2 mm. The width of the molding space determines the thickness of the product, and the width can be adjusted according to the actual product thickness.

[0046] In a preferred embodiment, the width of the molding space is 2 mm, and when the glue injection structure is used to prepare a high-gloss product with a thickness of 2 mm, the effect can be optimal.

[0047] In some embodiments, the glue injection structure further includes a base 30 , and the base 30 is located on a side of the first molded part 21 away from the sealing part 22 .

[0048] In some embodiments, the base 30 , the first molding piece 21 , and the second molding piece enclose the molding space.

[0049] In summary, the utility model provides a glue feeding structure for high-gloss products, including: a glue feeding component for outputting liquid colloid; a molding component, including a first molding part and a second molding part forming a sleeve structure with the first molding part, and a molding space is provided between the first molding part and the second molding part; the molding component also includes a sealing part arranged at one end of the first molding part close to the glue feeding component; the sealing part is recessed in a direction away from the glue feeding component to form a buffer groove. The utility model provides a sealing part at one end of the first molding part close to the glue feeding component, and recesses in a direction away from the glue feeding component to form a buffer groove, and uses the sealing part to seal the open part of the product for glue feeding, which can improve the molding yield and molding cycle, and solve the poor appearance defects caused by the glue feeding problem of the product. At the same time, the buffer groove is used to buffer the liquid colloid, which can improve the glue flow molding, so that the liquid colloid enters the molding space evenly, and the defects such as air marks and punching marks on the product are avoided, thereby forming a high-gloss product.
