[0030] In addition, if the terms "first", "second" and the like are used herein, they are merely used to distinguish one entity from another, and do not imply or suggest relative importance.

[0031] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0032] Please combine Figures 1 to 2 The horn glue inlet structure is used in a mold.

[0033] The horn glue inlet structure comprises a horn glue inlet 1, a glue inlet runner 2 and a runner section 3. The runner section 3 comprises a first side 31 and a second side 32 opposite to the first side 31. The horn glue inlet 1 is installed on the first side 31 and communicates with the runner section 3. The second side 32 is a plane. The runner section 3 also communicates with the glue inlet runner 2. The thickness of the runner section 3 is less than that of the glue inlet runner 2.

[0034] It can be understood that the runner section 3 of the horn glue inlet structure comprises a first side 31 and a second side 32 opposite to the first side 31. The horn glue inlet 1 is installed on the first side 31 and communicates with the runner section 3. The second side 32 is a plane, so that the manufacturing process of the runner section 3 and the horn glue inlet 1 is relatively simple. The runner section 3 also communicates with the glue inlet runner 2. The thickness of the runner section 3 is less than that of the glue inlet runner 2, so that the runner section 3 will be bent during the process of the nozzle ejector pin ejecting the horn glue inlet 1 from the mold, and will not cause the runner section 3 to break, thereby enabling the horn glue inlet 1 to be smoothly ejected from the mold, so as to avoid the horn glue inlet 1 falling on the mold and affecting production.

[0035] It should be noted that, in the prior art, the horn glue inlet 1 communicates with a part of the runner. A sheet type runner is arranged between the runner and the glue inlet runner 2, so that the process is increased in difficulty. In the present application, the horn glue inlet 1 is installed on the first side 31 and communicates with the runner section 3. The second side 32 is a plane, so that the manufacturing process of the horn glue inlet 1 and the runner section 3 is simple and material is saved.

[0036] In the present embodiment, the thickness of the runner section 3 is 1.4mm to 1.6mm. Specifically, the thickness of the runner section 3 is 1.4mm, 1.5mm or 1.6mm. In the implementation, the thickness of the runner section 3 is 1.5mm, so that the horn glue inlet 1 and the glue inlet runner 2 can be prevented from breaking.

[0037] Further, the glue inlet runner 2 is also provided with a glue inlet nozzle 21. Molten plastic is injected from the glue inlet nozzle 21, passes through the glue inlet runner 2, the runner section 3 and the horn glue inlet 1, and then enters the mold cavity to fill the product.

[0038] Further, the shape of the runner section 3 is flat. In this way, the runner section 3 is in the form of a sheet connecting the horn inlet 1 and the runner 2, so that the runner section 3 has a certain elasticity.

[0039] In an embodiment, as shown in Figure 2 The horn inlet structure further comprises a first transition piece 4, which is installed at the connection between the horn inlet 1 and the runner section 3. By arranging the first transition piece 4, the strength of the connection between the horn inlet 1 and the runner section 3 can be enhanced during the ejection of the mold, so that the deformation of the runner section 3 occurs to enable the horn inlet 1 to be separated from the mold. The length of the cross section of the first transition piece 4 gradually increases from the first side 31 to the second side 32. In this way, the strength of the connection between the horn inlet 1 and the runner section 3 can be improved.

[0040] In an embodiment, as shown in Figure 1 and Figure 2 The horn inlet structure further comprises a first cold well 5 and a second cold well 6. The first cold well 5 is in communication with the runner section 3 at one part and in communication with the runner 2 at another part, and the second cold well 6 is in communication with the runner 2. Since the temperature of the molten plastic injected into the runner 2 decreases when it comes into contact with the runner 2, the molten plastic partially solidifies, which affects the product quality. By arranging the first cold well 5 and the second cold well 6, the molten plastic injected into the runner 2 and the runner section 3 enters the first cold well 5 and the second cold well 6, thereby improving the product quality.

[0041] In addition, the first cold well 5 and the second cold well 6 can assist in the positioning and guiding of the horn inlet 1 during the ejection movement.

[0042] In the embodiment, the horn inlet structure further comprises a second transition piece 7, which is installed at the connection between the first cold well 5 and the runner section 3. By arranging the second transition piece 7, the strength of the connection between the runner 2 and the runner section 3 can be enhanced during the ejection of the mold, so that the deformation of the runner section 3 occurs to enable the horn inlet 1 to be separated from the mold. The length of the cross section of the second transition piece 7 gradually increases from the first side 31 to the second side 32. In this way, the strength of the connection between the runner 2 and the runner section 3 can be improved.

[0043] Further, the first cold well 5 is arranged close to the horn inlet 1. Specifically, during the ejection of the mold by the first nozzle pin 8 pushing the first cold well 5, the first cold well 5 is arranged close to the horn inlet 1, so that the first cold well 5 can more easily drive the horn inlet 1 to be separated from the mold.

[0044] In an embodiment, as shown in Figure 1As shown, the horn glue inlet structure further comprises a first nozzle pin 8 and a second nozzle pin 9, the first nozzle pin 8 is arranged in the first cold material well 5 and connected with the pin plate, and the second nozzle pin 9 is arranged in the second cold material well 6 and connected with the pin plate. The pin plate drives the first nozzle pin 8 and the second nozzle pin 9 to move, the first nozzle pin 8 and the second nozzle pin 9 drive the first cold material well 5 and the second cold material well 6 to move respectively, and the first cold material well 5 and the second cold material well 6 drive the glue inlet runner 2, the runner section 3 and the horn glue inlet 1 to separate from the mold.

[0045] In the embodiment, the second cold material well 6 is provided with a notch 61. By arranging the notch 61, the cold material falling into the second cold material well 6 can be hooked, so that the cold material cannot fall alone in the mold, and the edge manipulator takes it out.

[0046] Further, the first cold material well 5 can also be provided with a notch 61. The cold material falling into the second cold material well 6 can be hooked, so that the cold material cannot fall alone in the mold, and the edge manipulator takes it out.

[0047] The utility model also provides a mold, the mold includes horn glue inlet structure of any embodiment above.

[0048] It can be understood that the mold of the utility model uses the horn glue inlet structure above, so that the runner section 3 of the horn glue inlet structure comprises a first side 31 and a second side 32 opposite to the first side 31, the horn glue inlet 1 is installed on the first side 31 and communicates with the runner section 3, the second side 32 is a plane, so that the manufacturing process of the runner section 3 and the horn glue inlet 1 is relatively simple, the runner section 3 also communicates with the glue inlet runner 2, the thickness of the runner section 3 is less than the thickness of the glue inlet runner 2, so that in the process that the nozzle pin ejects the horn glue inlet 1 from the mold, the runner section 3 will be bent and will not cause the runner section 3 to break, so that the horn glue inlet 1 can be smoothly ejected from the mold, to avoid that the horn glue inlet 1 falls on the mold and affects production.

[0049] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.
