[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1 to 4 As shown, this utility model provides a wire harness bracket molding mold, including a base 1 and a moving mold base 2. The front and rear sides of the top of the base 1 are provided with lower templates 3. The lower template 3 is composed of a first molding seat 31 and a second molding seat 32. The first molding seat 31 and the second molding seat 32 are separable. The surface of the lower template 3 is connected to an injection tube 11. Each cavity 10 is provided with an injection tube 11. The injection tube 11 is connected to an external injection molding system to inject injection liquid into the cavity 10. Locking mechanisms 4 are provided on both sides of the lower template 3.

[0029] The locking mechanism 4 includes a first mounting plate 41 fixed to the side of the lower template 3, a second mounting plate 42 provided on the surface of the first mounting plate 41, a through rod 43 provided between the first mounting plate 41 and the second mounting plate 42, a through groove 44 provided inside the through rod 43, and protrusions 45 slidably connected on the upper and lower sides of the inner wall of the through groove 44, and a spring 46 fixedly connected between the two protrusions 45.

[0030] The front and rear sides of the bottom of the moving mold base 2 are provided with upper templates 5. The top two sides of the upper templates 5 are fixedly connected with screws 6. The two sides of the moving mold base 2 are fixedly connected with protrusions 7. The end of the screw 6 that passes through to the outside of the protrusion 7 is threaded with a nut 8, which facilitates the disassembly and assembly of the upper templates 5.

[0031] The bottom of the upper template 5 is fixedly connected to the core 9, and the top of the lower template 3 is provided with a cavity 10 that matches the core 9. The core 9 and the cavity 10 are matched. The specific shape of the core 9 and the cavity 10 is set according to the requirements in actual production. Multiple cores 9 and cavities 10 are provided and evenly distributed on the upper template 5 and the lower template 3, which can realize the processing of multiple products at one time and improve production efficiency.

[0032] With the above structure, the protrusion 45 is pressed into the through groove 44, and the protrusion 45 compresses the spring 46. After the protrusion 45 is fully inserted into the through groove 44, the insert rod 43 can be pulled out between the first mounting plate 41 and the second mounting plate 42, so that the lower template 3 can be removed from the base 1. The cavity 10 on the lower template 3 can be replaced according to the shape and size of the product to be processed. During installation, the insert rod 43 is passed through the first mounting plate 41 and the second mounting plate 42. Under the reaction force of the spring 46, the protrusion 45 pops out of the through groove 44, which can limit the installation of the lower template 3. By unscrewing the nut 8 out of the screw 6, the upper template 5 can be removed from the moving mold base 2, and the core 9 can be replaced accordingly. The disassembly and assembly are simple and quick, which expands the application range of the mold and makes it flexible in use.

[0033] Example 2

[0034] Based on Example 1, please refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, a drive mechanism 12 is provided on both sides of the lower template 3. The drive mechanism 12 includes a housing 121 fixed to the side of the base 1 by a support plate. A motor 122 is fixedly connected to the inner wall of the housing 121. The motor 122 is connected to an external power supply through wires and controlled by an external switch. A bidirectional lead screw 123 is fixedly connected to the output end of the motor 122. Movable blocks 124 are threadedly connected to both sides of the surface of the bidirectional lead screw 123. The upper and lower sides of the movable blocks 124 are slidably connected to the inner wall of the housing 121. The opposite sides of the two movable blocks 124 are fixedly connected to the surface of the second mounting plate 42 by a fixing plate 125.

[0035] A discharge port 13 is provided on the top of the base 1 and directly below the cavity 10. A collection frame 14 is provided inside the base 1. The collection frame 14 is movably disposed inside the base 1 for easy handling.

[0036] After injection molding, the moving mold base 2 drives the core 9 to move out of the cavity 10. By starting the motor 122, the bidirectional lead screw 123 is driven to rotate, causing the two movable blocks 124 to move in opposite directions on the bidirectional lead screw 123. This causes the first molding seat 31 and the second molding seat 32 to separate through the second mounting plate 42. After the first molding seat 31 and the second molding seat 32 are separated, the discharge port 13 is exposed, allowing the workpiece in the cavity 10 to directly enter the collection frame 14 from the discharge port 13. This achieves automatic unloading of the molded workpiece, reduces manual operation time, and improves production efficiency.

[0037] Example 3

[0038] Please refer to Embodiment 1 and Embodiment 2 for details. Figure 1 As shown, a pad 15 is fixedly connected to the bottom of the base 1, and positioning cylinders 16 are fixedly connected to the four corners of the top of the pad 15. A top plate 17 is fixedly connected to the top of the moving mold base 2, and a positioning rod 18 that matches the positioning cylinder 16 is fixedly connected to the bottom of the top plate 17.

[0039] With the above structure, when the moving mold base 2 drives the core 9 downward into the cavity 10, the positioning rod 18 enters the positioning cylinder 16 to guide the mold, ensuring that each part of the mold is precisely aligned during operation and improving processing accuracy.

[0040] Furthermore, all contents not described in detail in this specification are existing technologies known to those skilled in the art, and each electrical appliance is connected to an external power source via wires, and conventional equipment suitable for the device can be used.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
