Description

Technical Field

[0001] This utility model relates to the field of fire hose production technology, specifically to a fire hose extrusion mold with positioning and locking. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. Fire hoses are divided into two categories: lined fire hoses and leak-proof fire hoses. Traditional fire hoses have a rubber inner lining and an outer layer covered with woven linen. Advanced fire hoses are made of polymer materials such as polyurethane. The extruder head on a fire hose extruder is usually fixed to the extruder's outlet with multiple bolts. Installing the extruder head requires workers to align the mounting holes on the extruder head with the bolt holes on the extruder, and then tighten the bolts one by one using a wrench or screwdriver. This process is inconvenient for both quick installation and removal of the extruder head, significantly reducing the efficiency of installation and removal. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a fire hose extrusion mold with positioning and locking.

[0004] The technical solution adopted by this utility model to solve its technical problem is a fire hose extrusion mold with positioning and locking, including an extruder. A positioning seat is fixed at the discharge port of the extruder. A first heat insulation sleeve is fixed inside the positioning seat. An extrusion head is provided inside the first heat insulation sleeve. Two hydraulic cylinders are fixed on the side of the positioning seat away from the extruder. Supports are fixed on the piston rods of the two hydraulic cylinders. Two T-shaped locking blocks are provided on the side of the extrusion head away from the extruder. Both supports are provided with through grooves for the ends of the locking blocks to pass through. Stops are fixed on both sides of the two locking blocks. Two crossbars are fixed on the opposing sidewalls of the two supports. A spring is sleeved on each crossbar. A through hole adapted to the crossbar is provided on each stop.

[0005] By adopting the above technical solution, during installation, pulling the two locking blocks to move them in opposite directions causes the stop block to compress the spring, which then contracts and deforms. After the extruder head is placed in the first heat insulation sleeve, the two locking blocks are released. As the spring returns to its original state, it pushes the stop block to reset. After the two locking blocks are reset, they are located on the side of the extruder head away from the extruder. The piston rods of the two hydraulic cylinders drive the two supports to move towards the extruder, and the two locking blocks move towards the extruder accordingly. Finally, the two locking blocks can press the extruder head, which facilitates the positioning and installation of the extruder head. During disassembly, the piston rods of the two hydraulic cylinders drive the two supports to move away from the extruder, releasing the pressure on the extruder head. Pulling the two locking blocks to move them in opposite directions allows the extruder head to be removed by pulling it out.

[0006] Specifically, each of the two supports has two guide rods fixed to the side wall near the positioning seat, and each guide rod has a sleeve at its end, and each sleeve is connected to the positioning seat.

[0007] By adopting the above technical solution, the arrangement of the guide rod and sleeve can improve the stability of the support.

[0008] Specifically, handles are fixed to the opposite sidewalls of the two locking blocks.

[0009] By adopting the above technical solution, the handle design facilitates the pulling of the locking block.

[0010] Specifically, handles are fixed on both sides of the extrusion head.

[0011] By adopting the above technical solution, the handle makes it convenient to pick up and put down the extruder head.

[0012] Specifically, a second heat insulation sleeve is fixed to both handles.

[0013] By adopting the above technical solution, the second heat insulation sleeve can prevent hands from being burned when holding the handle.

[0014] The beneficial effects of this utility model are:

[0015] (1) The fire hose extrusion mold with positioning and locking described in this utility model is installed by pulling the two locking blocks to move in opposite directions. The stop block squeezes the spring, and the spring contracts and deforms. After the extrusion head is placed in the first heat insulation sleeve, the two locking blocks are released. During the process of the spring returning to its original state, the stop block is pushed to reset. After the two locking blocks are reset, they are located on the side of the extrusion head away from the extruder. The piston rods of the two hydraulic cylinders drive the two supports to move towards the extruder. The two locking blocks move towards the extruder accordingly. Finally, the two locking blocks can press the extrusion head, which facilitates the positioning and installation of the extrusion head. When disassembling, the piston rods of the two hydraulic cylinders drive the two supports to move away from the extruder, release the pressure on the extrusion head, pull the two locking blocks to move in opposite directions, and pull the extrusion head to remove it.

[0016] (2) The fire hose extrusion mold with positioning and locking described in this utility model has a guide rod and sleeve, which can improve the stability of the support. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] To facilitate the installation and removal of the extruder head 3, as one embodiment of this utility model, such as Figures 1 to 4 As shown, the present invention discloses a fire hose extrusion mold with positioning and locking, comprising an extruder 1, a positioning seat 2 welded and fixed at the discharge port of the extruder 1, a first heat insulation sleeve 4 fixed inside the positioning seat 2 by adhesive, and an extrusion head 3 provided inside the first heat insulation sleeve 4. The extruder 1 and the extrusion head 3 are existing technologies, and their specific principles will not be elaborated here. Two hydraulic cylinders 5 are bolted to the side of the positioning seat 2 away from the extruder 1, and a support 8 is bolted to the piston rod of each of the two hydraulic cylinders 5. Two T-shaped locking blocks 10 are provided on the side of the extrusion head 3 away from the extruder 1. Each of the two supports 8 is provided with a through groove for the end of the locking block 10 to pass through. A stop block 11 is welded and fixed to both sides of each of the two locking blocks 10. Two crossbars 13 are welded and fixed to the opposing sidewalls of the two supports 8. A spring 12 is sleeved on each crossbar 13, and a through hole adapted to the crossbar 13 is provided on each stop block 11.

[0026] In use, by pulling the two locking blocks 10 back to back, the stop block 11 compresses the spring 12, and the spring 12 contracts and deforms. After the extruder head 3 is placed in the first heat insulation sleeve 4, the two locking blocks 10 are released. During the process of the spring 12 returning to its original state, it pushes the stop block 11 to reset. After the two locking blocks 10 are reset, they are located on the side of the extruder head 3 away from the extruder 1. The piston rods of the two hydraulic cylinders 5 (existing technology) drive the two supports 8 to move towards the extruder 1. The two locking blocks 10 then move towards the extruder 1. Finally, the two locking blocks 10 can press the extruder head 3, which facilitates the positioning and installation of the extruder head 3. When disassembling, the piston rods of the two hydraulic cylinders 5 drive the two supports 8 to move away from the extruder 1. The two locking blocks 10 move away from the extruder head 3, releasing the pressure on the extruder head 3. By pulling the two locking blocks 10 back to back, the extruder head 3 can be removed.

[0027] To improve the stability of support 8, for example, such as Figure 2 As shown, two guide rods 7 are welded and fixed to the side walls of the two supports 8 near the positioning seat 2. Each guide rod 7 has a sleeve 6 at its end, and each sleeve 6 is welded to the positioning seat 2.

[0028] To facilitate pulling the locking block 10, for example, such as Figure 2 As shown, handles 9 are welded and fixed to the opposite sidewalls of the two locking blocks 10.

[0029] To facilitate the handling of the extruder head 3, for example, as shown... Figure 5 As shown, handles 14 are welded and fixed on both sides of the extrusion head 3.

[0030] To protect hands, for example, such as Figure 5 As shown, a second heat insulation sleeve 15 is fixed to both handles 14 by adhesive.

[0031] In use, the two locking blocks 10 are pulled by hand to move them in opposite directions. The stop block 11 compresses the spring 12, and the spring 12 contracts and deforms. After the extruder head 3 is placed in the first heat insulation sleeve 4, the two locking blocks 10 are released. During the process of the spring 12 returning to its original state, it pushes the stop block 11 to reset. After the two locking blocks 10 are reset, they are located on the side of the extruder head 3 away from the extruder 1. The piston rods of the two hydraulic cylinders 5 (existing technology) drive the two supports 8 to move towards the extruder 1. The two locking blocks 10 move towards the extruder 1 accordingly. Finally, the two locking blocks 10 can press the extruder head 3, which facilitates the positioning and installation of the extruder head 3. The working principle of the extruder 1 is existing technology and will not be described in detail.

[0032] When the extruder head 3 is disassembled, the piston rods of the two hydraulic cylinders 5 drive the two supports 8 to move away from the extruder 1, and the two locking blocks 10 move away from the extruder head 3, releasing the pressure on the extruder head 3. Pull the two locking blocks 10 to move in opposite directions, and the extruder head 3 can be removed by pulling it out.
