The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.

[0022] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0023] See also Figure 1-5 A horn glue injection assembly for injection molding of an automobile air-conditioning air outlet knob comprises a lower mold core 1 and a glue injection insert 2; wherein the lower mold core 1 has a lower cavity 11 and a first glue injection flow channel 12; the cavity 11 comprises a cavity bottom wall 111 for molding the bottom surface of the automobile air-conditioning air outlet knob and a cavity side wall 112 for molding the knob side 31; the first glue injection flow channel 12 is arranged to pass through from the side wall of the lower mold core 1 to the cavity bottom wall 111; wherein the glue injection insert 2 is arranged on the side wall of the lower mold core 1; the glue injection insert 2 has a second glue injection flow channel 21; the second glue injection flow channel 21 is arranged to communicate with the first glue injection flow channel 12; the molten plastic material enters the cavity 11 through the second glue injection flow channel 21 and the first glue injection flow channel 12, so as to mold the automobile air-conditioning air outlet knob through the cavity 11.

[0024] In actual use, the lower mold core 1 of the utility model is provided with a first glue inlet channel 12, and the first glue inlet channel 12 is communicated with the cavity bottom wall 111 of the lower cavity 11, so that the molten plastic material can be injected into the lower cavity 11 from the cavity bottom wall 111, thereby ensuring that the cavity side wall 112 can form a molding surface, so as to eliminate the splicing line of the knob side 31; the utility model is also provided with a glue inlet insert 2, the glue inlet insert 2 is arranged on the side wall of the lower mold core 1 and is not embedded in the cavity 11, so as to maintain the integrity of the cavity side wall 112, and prevent the appearance of a splicing line on the side wall of the automobile air-conditioning outlet knob, and the glue inlet insert 2 includes a second glue inlet channel 21, so as to connect the external injection molding equipment and the first glue inlet channel 12, thereby ensuring the injection of the molten plastic material.

[0025] Please continue reading Figure 2 , wherein the lower mold core 1 includes a mold core body 13, a first cut surface 14 arranged on the side of the mold core body 13, and a slot 15 extending from the first cut surface 14 toward the inside of the mold core body 13; the glue insert 2 includes a glue insert body 22, a second cut surface 23 arranged on one side of the glue insert body 22, and a block 24 protruding outward from the second cut surface 23; the second cut surface 23 is arranged to fit with the first cut surface 14; the block 24 is arranged to fill the slot 15.

[0026] Specifically, during the injection molding process of the automobile air-conditioning outlet knob, the injection pressure is relatively large. Through the matching design of the slot 15 and the block 24, the lower mold core 1 and the glue insert 2 can remain relatively still during injection molding to prevent relative sliding between the two and resulting in poor glue injection.

[0027] Please continue reading Figure 2 , Figure 3 , Figure 5, wherein the first glue inlet channel 12 has a first glue inlet 121 and a first glue outlet 121; the first glue inlet 121 is arranged in the card slot 15, and the first glue outlet 121 is arranged on the bottom wall 111 of the cavity; the second glue inlet channel 21 has a second glue inlet 211 and a second glue outlet 212; the second glue inlet 211 is arranged in the glue insert body 22, and the second glue outlet 212 is arranged in the card block 24.

[0028] Under this arrangement, the molten plastic material can enter from above the glue inlet insert 2, pass through the horn-shaped integral flow channel composed of the first glue inlet flow channel 12 and the second glue inlet flow channel 21, and enter from the cavity bottom wall 111 at the bottom of the cavity 11, thereby bypassing the cavity side wall 112 to maintain the integrity of the cavity side wall 112 and avoid the appearance of a parting line on the knob side 31.

[0029] Please continue reading Figure 5 , wherein the first glue inlet 121 is configured to be connected to the second glue outlet 212; the inner size of the second glue outlet 212 is configured to be larger than the first glue inlet 121; under this configuration, the second glue outlet 212 and the first glue inlet 121 can be prevented from being misaligned during installation, and the injection material in the shape of a bull horn cannot be ejected from the mold in the overall flow channel.

[0030] Please continue reading Figure 5 , wherein the included angle between the end face where the first glue inlet 121 is located and the end face where the first glue outlet 121 is located is set to 30°-50°.

[0031] Specifically, the size from the second glue inlet runner 21 to the first glue inlet runner 12 is gradually reduced. In the process of the molten plastic material flowing from the second glue inlet runner 21 to the first glue inlet runner 12, if the length of the first glue inlet runner 12 is too long, the processing time will be increased, and if it is too short, it will be difficult to ensure the thickness of the material between the cavity 11 and the first section 14, which will cause the position to have the risk of deformation; when the angle between the end face where the first glue inlet 121 is located and the end face where the first glue outlet 121 is located is set to the range of 30°-50°, the processing time and the thickness of the material between the cavity 11 and the first section 14 can be taken into account.

[0032] Please continue reading Figure 2 , Figure 3 , wherein the mold body 13 is set as a rectangular parallelepiped, and the first section 14 is set on one of the edges of the rectangular parallelepiped; under this setting, the size of the diagonal of the rectangular parallelepiped can be used to process the first glue inlet channel 12, and the side length of the rectangular parallelepiped is made smaller, which is beneficial to saving materials and reducing the overall size of the mold.

[0033] The above description is only for the best embodiment of the utility model, but it cannot be understood as a limitation of the claims. The utility model is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the protection scope of the independent claims of the utility model are within the protection scope of the utility model.
