[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4A self-cleaning injection mold for fire-fighting spare parts includes a base 1, which serves as the core support platform for the entire mold system. Fixed to the injection molding machine's worktable, the base 1 provides a stable foundation for the parts. A support frame 2 is mounted on the surface of the base 1, and a support plate 3 is mounted on the surface of the support frame 2. The support frame 2 connects the base 1 and the support plate 3, forming a robust vertical support structure to bear the weight and movement load of the cylinder 4 and the upper mold 7. The support plate 3 serves as a direct mounting platform for the cylinder 4, transmitting the thrust of the cylinder 4 to the upper mold 7. The cylinder 4 is mounted on the surface of the support plate 3, driving the upper mold 7. The cylinder 4 is vertically raised and lowered along the guide rod 9 to achieve mold closing and opening. An upper mold 7 is located at the end of the cylinder 4, and an injection tube 22 penetrates the surface of the upper mold 7. Driven by the cylinder 4, the upper mold 7 closes with the lower mold to form an injection cavity. Molten plastic is injected through the injection tube 22 to form fire-fighting components. During the injection molding process, both the upper and lower molds have vent holes on their sides for venting. This ensures that the molten plastic fills the cavity evenly, preventing high-temperature burns and material decomposition caused by gas compression, and reducing surface and internal defects such as bubbles and air bubbles. The upper mold 7 has guide rods on its sides. Guide rods 9 are provided on the surface of the base 1 and the guide block 8. The guide block 8 slides with the guide rods 9 on the base 1 to guide the upper mold 7 to move precisely in the vertical direction. This, combined with the cylinder 4, achieves smooth mold closing and opening, ensuring high-precision production of fire-fighting parts molds. The surface of the base 1 is provided with a placement groove 11, which serves as the positioning and fixing area for the first splicing block 6 and the second splicing block 19, providing the installation base for the modular lower mold.

The surface of the mounting plate 10 has mounting bolts 18, and the surface of the positioning plate 15 has positioning bolts 16. The positioning grooves 17 are opened on the top surfaces of the first splicing block 6 near the cleaning component 5 and the two second splicing blocks 19, serving as the receiving end of the positioning plate 15. The positioning plate 15 is set on the top surfaces of the second splicing blocks 19 and the first splicing block 6 away from the cleaning component 5. The positioning bolts 16 are inserted into the positioning grooves 17 to enhance the positioning accuracy between modules, improve splicing stability, prevent micro-movement of modules during injection molding, and ensure cavity consistency.

[0025] First, place the first splicing block 6 and the second splicing block 19 into the placement slot 11 in the designed order. The side handle 20 facilitates handling.
