[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Reference Figures 1-4 The present invention provides an embodiment of a valve mold, comprising a support base 1, an opening and closing component connected to the top of the support base 1, a detachable component connected inside the opening and closing component, and a collection component connected inside the support base 1.

[0031] The opening and closing assembly includes a fixed plate 2, which is fixedly connected to the top of the support base 1. Two sets of fixed plates 2 are symmetrically arranged, and a bidirectional lead screw 3 is rotatably connected between the two sets of fixed plates 2. Both sides of the outer wall of the bidirectional lead screw 3 are threadedly connected to movable plates 4. The bottom of the movable plates 4 slides inside the support base 1. A first mold 21 is connected to the side of one set of movable plates 4, and a second mold 22 is connected to the side of the other set of movable plates 4. One end of the bidirectional lead screw 3 passes through a set of fixed plates 2 and is connected to a limiting component to facilitate fixing the rotation position of the bidirectional lead screw 3.

[0032] The limiting assembly includes a fixed plate 5, which is fixedly connected to one end of a bidirectional lead screw 3. The fixed plate 5 has multiple limiting holes 6. One set of limiting holes 6 has a sliding groove 7 within a fixed plate 2, and a connecting rod 8 is slidably connected within the sliding groove 7. A limiting plate 9 is fixedly connected to the outer wall of the connecting rod 8. A first spring 10 is fixedly connected between the limiting plate 9 and the fixed plate 2, and the first spring 10 is sleeved on the outside of the connecting rod 8. One end of the connecting rod 8 is slidably connected within the limiting hole 6. The detachable assembly includes a connecting plate 12, which has two symmetrically arranged sets. The connecting plate 12 has a slot 13. A moving plate 4 has a connecting groove 11 and a square groove 14. An L-shaped plate 15 is fixedly connected to the side of the moving plate 4. A circular groove is formed within the L-shaped plate 15. The inner sliding connection includes a slide rod 16, with a locking block 17 fixedly connected to one end of the slide rod 16. A second spring 18 is fixedly connected between the locking block 17 and the L-shaped plate 15. The second spring 18 is sleeved on the outside of the slide rod 16. The locking block 17 is slidably connected in the locking groove 13 and the square groove 14. The connecting plate 12 is slidably connected in the connecting groove 11. The collection assembly includes a collection box 20. A limiting groove 19 is opened in the support base 1. The collection box 20 is slidably connected in the limiting groove 19. Handles 23 are fixedly connected to both sides of the collection box 20. One set of connecting plates 12 is fixedly connected to the first mold 21, and another set of connecting plates 12 is fixedly connected to the second mold 22. The bidirectional lead screw 3 is parallel to the support base 1. The locking block 17 is set in a right-angled trapezoid and can limit movement in one direction.

[0033] Working principle: In the valve mold, pressing the limiting plate 9 causes the connecting rod 8 to slide in the slide groove 7. At the same time, one end of the connecting rod 8 slides out from the limiting hole 6. The limiting plate 9 squeezes the first spring 10, and rotating the fixed plate 5 causes the double-acting screw 3 to rotate. This causes the double-acting screw 3 to drive the moving plates 4 on both sides to slide closer together at the bottom of the support base 1, making it easier to bring the first mold 21 and the second mold 22 closer together. Then, the limiting plate 9 is released. Under the action of the first spring 10, one end of the connecting rod 8 slides into the corresponding set of limiting holes 6 to fix the fixed plate 5, thereby fixing the first mold 21 and the second mold 22. This allows for a tight fit to form a cavity for pouring molten iron to make a valve. It also facilitates the production and removal of irregular valves after forming, avoiding the impact of irregular shape on removal. It is more convenient. Pulling the slide rod 16 outward causes the locking block 17 to move out of the locking block. The connecting plate 12 slides out of the groove 13, allowing it to be pulled out from the connecting groove 11. This facilitates the disassembly and replacement of the first mold 21 and the second mold 22 with different shapes and sizes, enabling the manufacture of valves according to requirements. It also facilitates the replacement of damaged first mold 21 and second mold 22. During installation, the connecting plate 12 slides in the connecting groove 11, and the connecting plate 12 slides in the inclined side of the locking block 17, thereby squeezing the locking block 17 to slide in the square groove 14. At the same time, the second spring 18 is squeezed. When the locking groove 13 moves to be aligned with the position of the locking block 17, the locking block 17 slides in the locking groove 13 under the action of the second spring 18, fixing the position of the connecting plate 12. The excess molten iron poured into the cavity after the first mold 21 and the second mold 22 are merged can be cleaned and collected in the collecting box 20 for easy disposal.
