[0021] The following is in conjunction with the appendix Figure 3-6 This application will be described in further detail.

[0022] This application discloses a hot runner mold that is easy to maintain.

[0023] Reference Figure 3-6 The easy-to-maintain hot runner mold includes a mold base 1, a mold core 2, a hot runner structure 3, a hot runner manifold 4, and a panel 5. The mold core 2 is installed in the mold base 1 by a first screw 21. The hot runner structure 3 is installed on the hot runner manifold 4 by a second screw 32. The hot runner manifold 4 is located on the top surface of the mold base 1. The hot runner structure 3 is installed on the top of the hot runner manifold 4. The panel 5 is installed on the top surface of the hot runner manifold 4 by a third screw 51.

[0024] A connecting hole 11 is provided on the top surface of the mold frame 1. A connecting hole 2 41 is provided on the hot runner manifold 4, which is opposite to and communicates with the connecting hole 11. The connecting holes penetrate the wall of the hot runner manifold 4 in the height direction. A connecting hole 3 52 is provided on the panel 5, which is opposite to and communicates with the connecting hole 2 41. The connecting hole 3 52 penetrates the wall of the panel 5 in the height direction. The connecting hole 11 is a threaded hole, and the connecting hole 3 52 is a countersunk hole. A connecting bolt 6 is provided in the connecting holes 11, 2 41, and 3 52. The connecting bolt 6 is threadedly connected to the connecting hole 11, and the nut of the connecting bolt 6 abuts against the top wall of the connecting hole 3 52.

[0025] When maintenance is required on the mold base 1 and mold core 2, loosen the connecting bolts 6 and remove them from the mold base 1. Then, the hot runner manifold 4, hot runner structure 3, and panel 5 can be removed together. During installation, place the hot runner manifold 4, hot runner structure 3, and panel 5 together on the mold base 1, and simultaneously insert the connecting bolts 6 into connecting holes 11, 41, and 52, and thread them into connecting hole 11 to complete the installation. This allows for quick disassembly and assembly of the hot runner manifold 4, hot runner structure 3, and panel 5 together, eliminating the need to separately disassemble and assemble panel 5 and hot runner structure 3. Regardless of whether panel 5 has complex wiring harnesses, water pipes, or air pipes, disassembly and assembly are simple, saving time and effort, improving efficiency, and facilitating maintenance or upkeep of the mold base 1 and mold core 2.

[0026] Multiple connecting bolts 6 are symmetrically arranged on both sides of the mold frame 1 in the width direction. The multiple connecting bolts 6 on each side of the mold frame 1 in the width direction are spaced apart to improve the connection stability between the mold frame 1 and the hot runner manifold 4, the hot runner structure 3, and the panel 5.

[0027] The mold base 1 is equipped with a guide post 7, and the hot runner manifold 4 is equipped with a guide rod 8. The top of the guide post 7 has a guide hole 71 for the guide rod 8 to move up and down. The guide rod 8 passes through the guide hole 71. When the hot runner manifold 4 is disassembled, the guide rod 8 slides along the guide hole 71 until it is disengaged from the guide hole 71. The bottom surface of the hot runner manifold 4 has a clearance hole 42 for the guide post 7 to pass through, and the top surface of the hot runner manifold 4 has a mounting hole 43 for the guide rod 8 to be installed. The mounting hole 43 is a countersunk hole, and the guide rod 8 is fixed in the mounting hole 43.

[0028] With the cooperation of the guide post 7 and the guide rod 8, the hot runner manifold 4 is guided during disassembly and assembly, reducing the possibility of damage to the nozzle 31 of the hot runner structure 3 when disassembling the hot runner manifold 4.

[0029] Multiple guide posts 7 are symmetrically arranged on both sides of the mold base 1 in the width direction, and guide rods 8 correspond one-to-one with guide posts 7. Multiple guide posts 7 on each side of the mold base 1 in the width direction are spaced apart. Multiple guide posts 7 on each side of the mold base 1 in the width direction are staggered along the width direction of the mold base 1. This improves the uniformity of the guiding effect when assembling and disassembling the hot runner manifold 4, hot runner structure 3, panel 5, and mold base 1, greatly reducing the possibility of damage to the nozzles 31 of the hot runner structure 3.

[0030] The implementation principle of a maintenance-friendly hot runner mold in this application embodiment is as follows: When maintenance is required on the mold base 1 and mold core 2, loosen the connecting bolts 6 and remove them from the mold base 1. Then, the hot runner manifold 4, hot runner structure 3, and panel 5 can be removed together. During installation, place the hot runner manifold 4, hot runner structure 3, and panel 5 together on the mold base 1, and simultaneously insert the connecting bolts 6 into connecting holes 11, 41, and 52, and thread them into connecting hole 11 to complete the installation. This allows for quick disassembly and assembly of the hot runner manifold 4, hot runner structure 3, and panel 5 together, eliminating the need to separately disassemble and assemble panel 5 and hot runner structure 3. Regardless of whether panel 5 has complex wiring harnesses, water pipes, or air pipes, disassembly and assembly are simple, saving time and effort, improving efficiency, and facilitating maintenance or upkeep of the mold base 1 and mold core 2.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
