[0001] The utility model relates to the technical field of valve plate molds, in particular to a valve plate mold with multiple parts in one mold. Background Art

[0002] A valve plate is an important component that needs to open or close the pipeline fluid in a valve. Its main function is to control the on-off and flow regulation of the medium by opening or closing. The valve plate is formed by casting through a valve plate mold, and a movable head is arranged in the mold to form connection holes for connecting with the valve stem at both ends of the valve plate.

[0003] During the use of the existing valve plate molds, when it is necessary to simultaneously cast and produce multiple valve plates, since it is not convenient to adjust the movable heads on both sides of the mold cavity of the mold core, the use effect of the valve plate mold is not good. Therefore, for the progress of the industry technology, to better realize the valve plate casting production function and improve the core technology competitiveness, this application proposes a new implementation scheme different from the structure and use method of the valve plate mold in the prior art. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that during the use of the existing valve plate molds, when it is necessary to simultaneously cast and produce multiple valve plates, since it is not convenient to adjust the movable heads on both sides of the mold cavity of the mold core, the use effect of the valve plate mold is not good, and a valve plate mold with multiple parts in one mold is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A valve plate mold with multiple parts in one mold includes a bottom plate. A lower mold is fixedly connected to the top of the bottom plate. An upper mold is arranged on the top of the lower mold. An outer frame is fixedly connected to the top of the bottom plate, and the outer frame is arranged outside the lower mold. Two motors are fixedly connected to one outer wall of the outer frame. A square rod is key-connected to the output end of the motor. A plurality of hollow threaded rods are fixedly sleeved on the outer wall of the square rod. The thread directions of adjacent hollow threaded rods are opposite. A sliding plate is thread-sleeved between opposite hollow threaded rods. Two movable heads are fixedly sleeved on the outer wall of the sliding plate. A plurality of guide rods are fixedly connected to both ends between the inner walls of the two sides of the outer frame, and the sliding plate is slidably sleeved with the guide rods.

[0007] Furthermore, side plates are fixedly connected to both sides of the upper mold.

[0008] Furthermore, a plurality of vertical rods are fixedly connected to the top of the bottom plate, and the side plates are slidably sleeved with the vertical rods.

[0009] Furthermore, two hydraulic cylinders are fixedly connected to both sides of the top of the bottom plate. One end of the piston rod of the hydraulic cylinder is rotatably connected with a fastening block through a rotating shaft.

[0010] Further, a plurality of bayonets are provided on one side of the side plate, and the fastening block is snap-fitted with the bayonets.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. By driving the square rod to rotate under the drive of the forward and reverse rotation of the motor, the hollow threaded rod is driven to rotate, and then the sliding plate is moved along the guide rod, so that the movable heads of the two sliding plates are gathered towards the middle or separated towards both sides, thus facilitating the adjustment of the movable heads on both sides of the cavity of the mold core.

[0013] 2. Through the arrangement of the sliding sleeve connection between the side plate and the vertical rod, the movement of the upper mold is guided, and the stability of the opening and closing of the lower mold and the upper mold is improved.

[0014] 3. By driving the fastening block to move upward under the drive of the hydraulic cylinder, the fastening block is moved to the position of the side plate, and then the fastening block is pulled to make it snap-fitted with the bayonet, so as to fix the upper mold and the lower mold for the subsequent forming of the valve plate mold.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Reference Figures 1 - 5 Figures 1 - 5 , a valve plate mold with multiple parts in one mold, includes a bottom plate 1. The top of the bottom plate 1 is fixed with a lower mold 2 by bolts. The top of the lower mold 2 is provided with an upper mold 3. The top of the bottom plate 1 is fixed with an outer frame 4 by bolts. The outer frame 4 is arranged outside the lower mold 2. One outer wall of the outer frame 4 is fixed with two motors 10 by bolts. The output end of the motor 10 is key-connected with a square rod 9. A plurality of hollow threaded rods 8 are fixedly sleeved on the outer wall of the square rod 9. The thread directions of adjacent hollow threaded rods 8 are opposite. A sliding plate 6 is thread-sleeved between the opposite hollow threaded rods 8. The sliding plate 6 is arranged on the top of the lower mold 2. Two movable heads 7 are fixedly sleeved on the outer wall of the sliding plate 6. Both ends between the inner walls on both sides of the outer frame 4 are welded with a plurality of guide rods 5. The sliding plate 6 is slidably sleeved with the guide rods 5. Driven by the forward and reverse rotation of the motor 10, the square rod 9 rotates, thereby driving the hollow threaded rods 8 to rotate, and further enabling the sliding plate 6 to move along the guide rods 5, so as to drive the movable heads 7 of the two sliding plates 6 to gather towards the middle or separate towards both sides, thus facilitating the adjustment of the movable heads on both sides of the mold cavity of the mold core.

[0023] Both sides of the upper mold 3 are fixed with side plates 11 by bolts. The top of the bottom plate 1 is welded with a plurality of vertical rods 12. The side plates 11 are slidably sleeved with the vertical rods 12, so as to guide the movement of the upper mold 3 and improve the stability of the opening and closing of the lower mold 2 and the upper mold 3. Both sides of the top of the bottom plate 1 are fixed with two hydraulic cylinders 13 by bolts. One end of the piston rod of the hydraulic cylinder 13 is rotatably connected with a fastening block 14 through a rotating shaft. A plurality of bayonet openings 15 are arranged on one side of the side plate 11. The fastening block 14 is clamped with the bayonet openings 15. Driven by the hydraulic cylinder 13, the fastening block 14 moves upward, so as to move the fastening block 14 to the position of the side plate 11, and then the fastening block 14 is pulled to make it clamped with the bayonet openings 15, thereby fixing the upper mold 3 and the lower mold 2.

[0024] The working principle of this embodiment: When in use, first, driven by the forward rotation of the motor 10, the square rod 9 rotates, thereby driving the hollow threaded rods 8 to rotate, and further enabling the sliding plate 6 to move along the guide rods 5, so as to drive the movable heads 7 of the two sliding plates 6 to gather towards the middle. Then, the upper mold 3 and the lower mold 2 are combined together. Next, driven by the hydraulic cylinder 13, the fastening block 14 moves upward, so as to move the fastening block 14 to the position of the side plate 11, and then the fastening block 14 is pulled to make it clamped with the bayonet openings 15, thereby fixing the upper mold 3 and the lower mold 2. Then, it is poured into the upper mold 3 and the lower mold 2 from the pouring port of the upper mold 3, and then wait for the valve plate to be formed;

[0025] After forming, the tightening block 14 is driven to move upward under the stretching of the hydraulic cylinder 13, so that the tightening block 14 is separated from the side plate 11. Then, the tightening block 14 is pulled down from the bayonet 15. Then, the upper die 3 and the lower die 2 are separated. Next, the square rod 9 rotates under the drive of the reverse rotation of the motor 10, so that the movable heads 7 of the two sliding plates 6 are separated from each other. After that, the valve plate can be taken out.
