DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, an injection mold for manufacturing a narrow-frame router shell includes a bottom plate 1 and a mold body 10. The mold body 10 is arranged above the bottom plate 1. A sealing groove 2 and a heat dissipation hole 5 are opened on the top of the bottom plate 1. An auxiliary enclosure 3 is fixedly connected to the top of the bottom plate 1. A fixed base 9 is arranged between the inner walls of the auxiliary enclosure 3. A positioning structure is arranged between the fixed base 9 and the bottom plate 1. Two injection ports 11 are fixedly connected to the outer side of the mold body 10. An injection cavity 18 is arranged inside the mold body 10. Both injection ports 11 are communicated with the injection cavity 18. A demolding frame 15 is arranged above the sealing groove 2. The outer side of the demolding frame 15 is slidably connected to the inner wall of the injection cavity 18. A lifting assembly is arranged on the top of the fixed base 9. The lifting assembly is used to drive the mold body 10 to move. The positioning structure includes two positioning rods 4. The two positioning rods 4 are fixedly connected to the top of the bottom plate 1. Two positioning holes 6 are opened at the bottom of the fixed base 9. The inner wall of the positioning hole 6 is slidably connected to the outer side of the positioning rod 4.

[0022] When manufacturing the narrow-frame router housing, the injection colloid is first injected into the mold body 10 through the two injection ports 11 on the outside of the mold body 10, so that the injection cavity 18 is filled. After cooling, the mold body 10 is moved by the lifting assembly, so that the mold inside the injection cavity 18 is demolded under the action of the demolding frame 15, and finally the fixed base 9 is pulled away from the inner wall of the auxiliary enclosure 3, thereby completing the manufacturing of the narrow-frame router housing, thereby reducing manual intervention, improving the demolding efficiency of the injection mold, and enabling the narrow-frame router housing to be quickly demolded.

[0023] like Figure 1-Figure 4As shown, the lifting assembly includes a threaded rod 16, which is rotatably connected to the top of the fixed base 9, and one end of the threaded rod 16 away from the fixed base 9 is rotatably connected to a cross connecting plate 13, and the outer side of the threaded rod 16 is threadedly connected to a cross connecting plate 12, and the outer side of the cross connecting plate 12 is fixedly connected to the mold body 10, and a mounting groove 7 is provided at the bottom of the fixed base 9 and between the two positioning holes 6, and a servo motor 8 is fixedly installed inside the mounting groove 7, and the output end of the servo motor 8 passes through the fixed base 9 and is fixedly connected to the threaded rod 16, and four connecting rods 14 are fixedly connected to the bottom of the cross connecting plate 13, and one end of the four connecting rods 14 extends to the inside of the injection cavity 18 and is fixedly connected to the demolding frame 15, and two fixing rods 17 are fixedly connected between the cross connecting plate 13 and the fixed base 9, and the heat dissipation hole 5 corresponds to the opening position of the mounting groove 7.

[0024] The threaded rod 16 is driven by the servo motor 8 to rotate between the fixed base 9 and the cross connecting plate 13, so that the cross connecting plate 12 outside the threaded rod 16 drives the mold body 10 to move. Since the demolding frame 15 is fixed above the sealing groove 2 under the action of the fixed rod 17, the demolding work of the injection mold can be completed under the action of the demolding frame 15 while the mold body 10 moves, thereby facilitating the rapid demolding of the injection mold, thereby improving the manufacturing efficiency of the narrow-frame router housing.

[0025] The utility model provides an injection mold for manufacturing a narrow-frame router shell, and the specific working principle is as follows: when manufacturing a narrow-frame router shell, firstly, the injection colloid is injected into the mold body 10 through two injection ports 11 on the outer side of the mold body 10, so that the injection cavity 18 is filled, and after cooling, the threaded rod 16 is driven by the servo motor 8 to rotate between the fixed base 9 and the cross connecting plate 13, so that the cross connecting plate 12 on the outer side of the threaded rod 16 drives the mold body 10 to move, and because the demolding frame 15 is fixed above the sealing groove 2 under the action of the fixed rod 17, the demolding work of the injection mold can be completed under the action of the demolding frame 15 while the mold body 10 moves, and finally the fixed base 9 is pulled away from the inner wall of the auxiliary enclosure 3, thereby completing the manufacturing of the narrow-frame router shell.
