[0019] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0020] Please refer to Figure 2 , an injection molded part structure, including an injection molded part body 1, the injection molded part body 1 having a glue mouth portion 11 and a fusion line 12, the glue mouth portion 11 is located at a corner position of the injection molded part body 1, and the fusion line 12 is located at another corner position of the injection molded part body 1.

[0021] From the above description, it can be seen that the beneficial effect of the present invention is that by setting the glue mouth 11 at a corner position of the injection molded part body 1 and setting the fusion line 12 at another corner position of the injection molded part body 1, the fusion line 12 can be effectively avoided from appearing at the weakest glue position of the product, thereby improving the strength and durability of the product and reducing the risk of bursting during the burst test.

[0022] Furthermore, the glue outlet portion 11 is provided on the side wall of the injection molded part body 1 .

[0023] From the above description, it can be seen that arranging the glue nozzle 11 on the side wall of the injection molded part body 1 can optimize the path of the raw material flowing into the cavity, reduce the resistance during the flow of the raw material, make the raw material flow into the cavity more evenly, and reduce the formation of the fusion line 12.

[0024] Furthermore, the top of the nozzle portion 11 is offset from the top plane of the injection molded part body 1 .

[0025] From the above description, it can be seen that the top of the glue mouth part 11 is offset from the top plane of the injection molded part body 1, which can further optimize the flow path of the raw material, reduce the impact of the raw material when flowing into the mold cavity, and reduce the probability of the formation of the fusion line 12; and because the top of the glue mouth part 11 is offset from the top plane of the injection molded part body 1, it can also reduce the risk of flashing on the top of the injection molded part body 1 when the glue mouth part 11 is cut off.

[0026] Furthermore, the distance between the top of the nozzle portion 11 and the top plane of the injection molded part body 1 is 0.2 mm to 1.3 mm.

[0027] From the above description, it can be seen that the distance between the top of the glue nozzle 11 and the top plane of the injection molded part body 1 is set to 0.2mm-1.3mm, which can ensure that the fit between the glue nozzle 11 and the injection molded part body 1 is more precise, help control the speed and direction of the raw material flow, and reduce the formation of the fusion line 12.

[0028] Furthermore, the distance between the top of the nozzle portion 11 and the top plane of the injection molded part body 1 is 0.5 mm to 1 mm.

[0029] From the above description, it can be seen that further limiting the distance between the top of the nozzle 11 and the top plane of the injection molded part body 1 to 0.5mm-1mm can more accurately control the flow of raw materials, further reduce the formation of the fusion line 12, and improve the consistency and quality of the product.

[0030] Furthermore, the distance between the top of the nozzle portion 11 and the top plane of the injection molded part body 1 is 7.5 mm.

[0031] From the above description, it can be seen that the distance between the top of the nozzle 11 and the top plane of the injection molded part body 1 is specifically set to 7.5 mm. In order to adapt to specific injection molding processes or product structure requirements, the above setting can ensure the stability of raw material flow and the molding quality of the product.

[0032] Furthermore, the shape of the glue mouth portion 11 is trapezoidal.

[0033] As can be seen from the above description, the shape of the glue mouth portion 11 is trapezoidal, which can optimize the flow characteristics of the raw material, reduce turbulence and impact during the flow of the raw material, and help reduce the formation of the fusion line 12.

[0034] Furthermore, a reinforcing piece is embedded in the injection molded part body 1 , and the reinforcing piece is located at the fusion line 12 .

[0035] As can be seen from the above description, embedding a reinforcing piece in the injection molded part body 1, especially at the fusion line 12, can significantly improve the strength of the area, reduce the weak points caused by the fusion line 12, and improve the durability and reliability of the product.

[0036] Furthermore, the reinforcement is made of metal.

[0037] As can be seen from the above description, the reinforcement is made of metal, which can provide higher strength and rigidity, effectively resist external loads, and reduce deformation and damage of the product, especially in key areas such as the fusion line 12.

[0038] Furthermore, there are multiple reinforcing pieces.

[0039] As can be seen from the above description, providing multiple reinforcing members can further enhance the overall strength of the injection molded part body 1, especially in the fusion line 12 area, by dispersing stress concentration, thereby improving the stability and durability of the product.
