Description

Technical Field

[0001] This utility model relates to the field of flange manufacturing technology, specifically to a manufacturing mold for valve flanges. Background Technology

[0002] In the field of industrial production, valves are key components for controlling fluid transport systems, and their performance and quality directly affect the operating efficiency and safety of the entire system. Flanges, as important components in valve connections, play a crucial role. However, traditional valve flange manufacturing molds have gradually revealed many problems during use, making it difficult to meet the needs of the rapid development of modern industry.

[0003] Existing valve flange manufacturing molds are typically one-piece structures, and once the core cavity and core are determined, they are difficult to change. If a mold originally suitable for small-diameter valve flanges is to be modified to produce large-diameter products, the original mold must be discarded and a new mold must be designed and manufactured because the core cavity and core cannot be replaced separately. The whole process not only consumes a lot of funds for the development of new molds, but also delays product delivery time due to the long manufacturing cycle, reducing the company's competitiveness in the market. Therefore, we propose a new type of valve flange manufacturing mold. Utility Model Content

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.

[0021] like Figure 1-6 As shown, this utility model provides a technical solution: a valve flange manufacturing mold, including a static mold 1 and a moving mold 2. The static mold 1 and the moving mold 2 are provided with snap-fit ​​grooves 3 on opposite sides. A core cavity mold 4 and a core mold 5 are slidably connected in the two snap-fit ​​grooves 3 respectively. A core cavity is provided at the upper end of the core cavity mold 4. A core is fixedly connected at the bottom end of the core mold 5. The longitudinal sections of the snap-fit ​​grooves 3, the core cavity mold 4, and the core mold 5 are all convex. Multiple limiting members 8 are provided on the sides of the static mold 1 and the moving mold 2. An edging ring groove 7 is provided on the surface of the core cavity of the core cavity mold 4. An edging ring block 6 is provided in the edging ring groove 7. The edging ring block 6 is connected to the static mold 1 through the limiting member 9. A through guide groove 11 is provided at the upper end of the moving mold 2 and the core mold 5.

[0022] In an optional embodiment: each limiting member 8 includes a T-shaped rod 801, a rotating plate 802 and two limiting blocks 803. The T-shaped rod 801 is fixedly installed on the side end of the stationary mold 1, the rotating plate 802 is sleeved on the outer surface of the T-shaped rod 801, the inner wall of the T-shaped rod 801 is always in contact with the outer wall of the stationary mold 1, and the two limiting blocks 803 are fixedly installed on the side end of the stationary mold 1.

[0023] It should be noted that by rotating the rotating plate 802 in both directions, the core cavity mold 4 can be limited and released, making it convenient to move the core cavity mold 4.

[0024] In an optional embodiment: the limiting member 9 includes a T-shaped groove 901, a T-shaped rod 902, a pull ring 903, and a limiting groove 905. The T-shaped groove 901 is formed on the side end of the stationary mold 1 and penetrates the side wall of the stationary mold 1. The T-shaped groove 901 is T-shaped. The T-shaped rod 902 is slidably connected inside the T-shaped groove 901. A connecting spring 904 is sleeved on the outer surface of the T-shaped rod 902. The two ends of the connecting spring 904 are respectively fixedly installed on the opposite side ends of the T-shaped rod 902 and the T-shaped groove 901. The side end of the edging ring block 6 is provided with a limiting groove 905.

[0025] It should be noted that the edging ring 6 can be fixedly hung on the core cavity mold 4 by the limiting component 2 9, and the operation is more convenient than using bolts.

[0026] In an optional embodiment: the longitudinal section of the T-shaped rod 902 and the longitudinal section of the limiting groove 905 are both rectangular, and one end of the T-shaped rod 902 is inclined.

[0027] It should be noted that the shapes of the limiting groove 905 and the second T-shaped rod 902 always remain in a mutually compatible state to ensure the fixing effect. The upper end of the second T-shaped rod 902 is set in an inclined shape. When the other edging ring block 6 is inserted, the second T-shaped rod 902 can be squeezed into the T-shaped groove 901 under the action of the inclined wall so that the edging ring block 6 can be inserted.

[0028] In an optional embodiment: a pull ring 903 is fixedly installed at one end of the T-shaped rod 902, and the pull ring 903 has a semi-circular cross-section.

[0029] It should be noted that pulling the T-shaped rod 902 outward by pulling the ring 903 makes the operation more convenient.

[0030] In an optional embodiment: a plurality of guide rods 10 are fixedly installed on the upper end of the stationary mold 1, and a plurality of through-flow channels 12 are opened on the upper end of the moving mold 2, with the distribution positions of the plurality of flow channels 12 and the plurality of guide rods 10 corresponding to each other.

[0031] It should be noted that the flow channel 12 is fitted on the outer surface of the guide rod 10, which provides a certain degree of guidance when the moving mold 2 moves up and down.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] When flanges of different sizes need to be manufactured, rotate the rotating plate 802 to release it from the constraint on the core cavity mold 4. This allows the core cavity mold 4 to be pulled out of the snap-fit ​​groove 3. Then, align another core cavity mold 4 with core cavities of different diameters with the snap-fit ​​groove 3 and push the core cavity mold 4 into the snap-fit ​​groove 3. Then, rotate the rotating plate 802 in the opposite direction to bring the side wall of the rotating plate 802 into contact with the side end of the core cavity mold 4, thus preventing lateral displacement of the core cavity mold 4. The limiting block 803 prevents the rotating plate 802 from continuing to rotate, thus acting as a limit. Similarly, the core mold 5 on the moving mold 2 can be replaced with a core of different diameter. When the edging ring block 6... When wear occurs, the T-shaped rod 902 is pulled outward by the pull ring 903. One end of the T-shaped rod 902 moves out of the limiting groove 905. Without the limiting force, the edging ring 6 can be removed from the core cavity and replaced with a new edging ring 6. Molten plastic is injected into the core cavity under high pressure. The edge of the core cavity is easily worn. The edging ring 6 can effectively protect the core cavity body and extend the service life of the mold. The core mold 5, core cavity mold 4, snap groove 3, edging ring 6 and edging ring groove 7 are all precision fitted to ensure that the solution and other substances will not enter the gaps. The guide groove 11 is set in the middle of the side of the core and the core mold 5, so that there are more choices for core molds 5 of different sizes.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
