Description

Technical Field

[0001] This utility model relates to the field of impeller shaft mold technology, and in particular to an irrigation valve impeller shaft mold. Background Technology

[0002] As a core component of agricultural irrigation systems, the design and manufacturing level of the mold for the impeller shaft of an irrigation valve directly affects the product's performance, lifespan, and production efficiency. With the increasing demands for water conservation, high efficiency, and intelligent manufacturing in modern agriculture, the technological development of impeller shaft molds must meet the requirements of high precision, high durability, and low-cost manufacturing. The impeller shaft is a key component in irrigation valves that drives the impeller's rotation and must withstand fluid impact, friction, and fatigue stress from long-term operation. Its structure typically includes a shaft body, impeller mounting position, and sealing mating surfaces, requiring high-precision machining to ensure sealing and stable operation. The mold is a crucial tool for the mass production of impeller shafts.

[0003] In existing irrigation valve impeller shaft mold technology, the upper mold base is driven by a hydraulic cylinder to fit against the lower mold base. This can easily generate a large force when the upper and lower mold bases are closed. However, the existing technology can only provide one buffer protection against the force and cannot eliminate the force significantly, which can lead to damage to the upper and lower mold bases and greatly increase production costs. Therefore, we propose an irrigation valve impeller shaft mold to solve this problem. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-3 A mold for an irrigation valve impeller shaft includes: a base 1, a connecting plate 8 fixedly mounted on the top of the base 1, multiple dampers 9 fixedly mounted on the top of the connecting plate 8, a lower mold base 3 fixedly mounted on the top of the multiple dampers 9, two rubber buffer pads 2 fixedly mounted on the top of the base 1, the tops of the two rubber buffer pads 2 fixedly mounted on the bottom of the lower mold base 3, an upper mold base 4 movably abutting the top of the lower mold base 3, a top plate 5 fixedly mounted on the top of the upper mold base 4, two support plates 12 fixedly mounted on the outer side of the top plate 5, two connecting blocks 24 fixedly mounted on the bottom of the two support plates 12, multiple rotating rods 23 hinged to the outer side of the four connecting blocks 24, a moving block 19 hinged to one end of the corresponding two rotating rods 23, a buffer spring 20 fixedly connected to the outer side of the four moving blocks 19, an arc-shaped block 17 fixedly connected to one end of the four buffer springs 20, and a limiting plate 25 fixedly mounted on the bottom of the corresponding two arc-shaped blocks 17.

[0016] In this embodiment, two fixing plates 13 are fixedly installed on both sides of the lower mold base 3. Two hydraulic cylinders 14 are fixedly installed on the top of each of the two fixing plates 13. The output ends of the four hydraulic cylinders 14 are fixedly connected to the bottom of the corresponding support plates 12. The bottom of the two limiting plates 25 is movably abutted against the top of the corresponding fixing plates 13. Two plug-in rods 15 are fixedly installed on the bottom of each of the two support plates 12. The outer sides of the two plug-in rods 15 are slidably sleeved on the outer side of the limiting plates 25. Two plug-in holes matching the plug-in rods 15 are opened inside the two fixing plates 13. The outer sides of the four plug-in rods 15 are movably abutted against the inner side of the corresponding plug-in holes. The cooperation between the plug-in rods 15 and the plug-in holes makes the upper mold base 4 and the lower mold base 3 fit more accurately.

[0017] In this embodiment, two telescopic columns 16 are fixedly installed on the top of each of the two limiting plates 25. The top ends of the four telescopic columns 16 are fixedly connected to the bottom of the corresponding support plate 12. A guide rod 18 is fixedly installed between the two arc-shaped blocks 17 on the same side. Four T-shaped sliders 21 are sleeved on the outside of the corresponding guide rods 18. Four moving blocks 19 are slidably sleeved on the outside of the corresponding guide rods 18. The guide rods 18 provide guidance for the movement of the moving blocks 19.

[0018] In this embodiment, the top of each of the two limiting plates 25 is provided with a T-shaped slide groove 22, and the bottom of each of the four moving blocks 19 is fixedly installed with a T-shaped slider 21. The bottom of the four T-shaped sliders 21 is slidably connected in the corresponding T-shaped slide groove 22. The mutual cooperation between the T-shaped sliders 21 and the T-shaped slide groove 22 makes the moving block 19 move more stably.

[0019] In this embodiment, the top of the top plate 5 is provided with an injection port 6, and a sealing plug 7 is movably inserted into the injection port 6. Multiple connecting rods 10 are fixedly installed on the outer sides of the upper mold base 4 and the lower mold base 3. The same locking block 11 is movably sleeved on the outer side of two corresponding connecting rods 10, so as to facilitate the fixing of the lower mold base 3 and the upper mold base 4 after they are attached by the connecting rods 10 and the locking block 11.

[0020] In this embodiment, during use, the hydraulic cylinder 14 is activated to drive the upper mold base 4 and the lower mold base 3 to close. At this time, the damper 9 and rubber buffer pad 2 at the bottom of the lower mold base 3 are compressed to eliminate the force for the first time. At the same time, the insertion rod 15 is inserted into the insertion hole of the fixing plate 13, so that the upper mold base 4 and the lower mold base 3 can be accurately fitted together. At this time, the limiting plate 25 and the fixing plate 13 are also fitted together. Simultaneously, the operation of the hydraulic cylinder 14 causes the telescopic column 16 to extend and retract, and the connecting block 24 to move vertically, thereby causing the rotating rod 23 to rotate. This causes the moving block 19 and the T-shaped slider 21 to move along the T-shaped slide groove 22 and... As the guide rods 18 move away from each other, the moving block 19 compresses the buffer spring 20, thus eliminating the force generated when the upper mold base 4 and lower mold base 3 are closed for the second time. This process continues until the upper mold base 4 and lower mold base 3 are in contact. The force is eliminated twice, resulting in a significant reduction in force and preventing damage to the upper mold base 4 and lower mold base 3, thereby greatly reducing production costs. Then, the locking block 11 is movably sleeved on the outside of the corresponding connecting rod 10 to fix the lower mold base 3 and upper mold base 4 again. Then, the sealing plug 7 is removed and injection is performed through the injection port 6, and then the sealing plug 7 is inserted to seal the mold.
