[0033] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1-Figure 8 The present invention provides a technical solution: a casting pouring system, the casting pouring system comprising: a seat plate 10, a column 7, a vertical plate 31 and a guide rod 29 are arranged above the seat plate 10, a top block 2 is arranged on the top of the column 7, a spring 3 is sleeved on the surface of the column 7, a vertical plate 6, a bottom plate 8 and an extension plate 11 are arranged on the side of the seat plate 10, a cylinder body 5 is arranged on the vertical plate 6, a second induction block 12 is arranged on the extension plate 11, an indicator light 13 is arranged on the side of the second induction block 12, and a lifting plate 4 is arranged above the lifting plate 4. A ridge plate 1 is provided, a top plate 17 is provided on one side of the ridge plate 1, an upper mold 16 and a first induction block 20 are provided at the bottom of the top plate 17, a lower mold 14 is provided below the top plate 17, a connecting plate 21 is provided at the bottom of the lifting plate 4, a roller 22 is rotatably connected to the connecting plate 21, an inner plate 23 is located between the lifting plate 4 and the seat plate 10, a bearing block 19 is provided above the inner plate 23, a support frame 24 is provided below the inner plate 23, a movable ball 27 is provided at the bottom of the support frame 24, and a guide hole 26 is provided on the surface of the support frame 24;

[0035] When in use, when the cylinder body 5 works, its output end will perform telescopic movement. Since the cylinder output end is connected to the connecting seat 25 and the support frame 24, the extension and contraction of the cylinder will drive the inner plate 23 to move left and right. The inner plate 23 is located between the lifting plate 4 and the seat plate 10, and is slidably connected to the guide rod 29 through the support frame 24. When the inner plate 23 moves left and right, it will drive the bearing plate above the inner plate 23 to move left and right. Figure 1 and Figure 2 At this time, the upper mold 16 and the lower mold 14 are in a separated state. At this time, the spring 3 is compressed and stores elastic potential energy. When the inner plate 23 moves to the left, the bearing block 19 will move to the left. At this time, the roller 22 is pushed downward and continues to contact and press against the bearing block 19. As the inner plate 23 continues to move to the left, the roller 22 will roll and move to the oblique angle side of the bearing block 19 until the roller 22 moves to the inner plate 23. While the roller 22 moves, the lifting plate 4 will move down synchronously, thereby causing the upper mold 16 to move down, and the upper mold 16 will cooperate with the lower mold 14 to complete the mold. When the mold needs to be opened, the cylinder body 5 is started so that the output end of the cylinder pushes the support frame 24, thereby driving the inner plate 23 to move right, thereby driving the bearing block 19 to move right, so that the roller 22 continuously contacts the hypotenuse of the bearing block 19 and continues to roll until the roller 22 moves to the top of the bearing block. During this process, the lifting plate 4 will rise and squeeze the spring 3 at the same time. The spring 3 is compressed and stores elastic potential energy. At the same time, the movement of the lifting plate 4 will drive the top plate 17 to move upward, thereby driving the upper mold 16 to be pulled out of the lower mold 14, thereby realizing the opening of the mold.

When the upper mold 16 and the lower mold 14 are completely closed, the first sensing block 20 and the second sensing block 12 sense each other, and the indicator light 13 lights up, indicating that it is safe to pour. If the mold is not closed, the indicator light 13 is not on, thereby preventing the occurrence of mis-pouring. When the lifting plate 4 moves and the spring 3 is compressed, the elastic potential energy stored in the spring 3 can absorb the vibration and deviation that may occur when the lifting plate 4 moves. At the same time, when the lifting plate 4 needs to move downward, the spring 3 can give the lifting plate 4 an effective thrust. At the same time, four groups of columns 7 are provided, and are evenly distributed on the lifting plate 4, providing stable support for the movement of the lifting plate 4, further improving the stability of the lifting plate 4, thereby improving the stability of the upper mold 16 when moving.

[0039] When in use, a number of ridge plates 1 are provided to connect the lifting plate 4 and the top plate 17, thereby improving the stability of the connection between the two and ensuring that the two can perform lifting operations synchronously. At the same time, when the top plate 17 moves, the provided balls are synchronously embedded in the grooves and continue to roll, providing certain lateral support for the top plate 17, thereby improving the smoothness and stability of the movement of the top plate 17.

[0040] Embodiment 4: On the basis of embodiment 3, the vertical plate 31 is fixed on the seat plate 10, and a guide rod 29 is fixed between the two groups of vertical plates 31. The guide rod 29 is provided with two groups, and the two groups of guide rods 29 are symmetrically distributed about the central axis of the bottom plate 8.

The bearing block 19 is provided with two groups. The cross-section of the bearing block 19 is trapezoidal, and the upper end of the bearing block 19 is rounded. The connecting plate 21 is installed on the lower surface of the lifting plate 4 by bolts, and the connecting plate 2 There are four groups of connecting plates 21 evenly distributed on the lower surface of the lifting plate 4, the rollers 22 can be close to the bearing block 19 and rotate, there are two groups of support frames 24, the two groups of support frames 24 are fixed to the bottom of the inner plate 23 by welding, the two groups of support frames 24 are respectively located on both sides of the bottom of the inner plate 23, guide holes 26 are opened on both sides of the support frames 24, guide rods 29 are located in the guide holes 26, the outer wall of the guide rod 29 and the inner wall of the guide hole 26 are slidably connected, and a movable ball 27 is provided at the bottom of the support frame 24, the movable ball 27 is located on the central axis of the support frame 24, and the movable ball 27 is embedded in the ball groove 30 and rolls;

[0041] During use, when the cylinder body 5 is started and the output end of the cylinder body 5 drives the support frame 24 to move, the support frame 24 will continue to move in the guide rod 29, and the movable ball 27 provided at the same time will be synchronously embedded in the ball groove 30 and continue to roll, thereby providing support and guidance for the movement of the inner plate 23 and the bearing block 19, improving the stability and smoothness of the movement of the bearing block 19, providing guarantee for the rise of the roller 22, ensuring the stability and precise positioning of the lifting plate 4 during the lifting process, and at the same time, the setting of the roller 22 and the bearing block 19 makes the lifting plate 4 smoother when moving.

[0042] In actual use, when the cylinder body 5 is working, its output end will perform telescopic movement. Since the cylinder output end is connected to the connecting seat 25 and the support frame 24, the extension and contraction of the cylinder will drive the inner plate 23 to move left and right. The inner plate 23 is located between the lifting plate 4 and the seat plate 10, and is slidably connected to the guide rod 29 through the support frame 24. When the inner plate 23 moves left and right, it will drive the bearing plate above the inner plate 23 to move left and right.

When the inner plate 23 moves to the left, the bearing block 19 will move to the left. At this time, the roller 22 is pushed downward and continues to contact and press against the bearing block 19. As the inner plate 23 continues to move to the left, the roller 22 will roll and move to the oblique angle side of the bearing block 19 until the roller 22 moves to the inner plate 23. While the roller 22 moves, the lifting plate 4 will move downward synchronously, thereby causing the upper mold 16 to move downward, and the upper mold 1 6 will cooperate with the lower mold 14 to complete the combination of the mold. When the mold needs to be opened, the cylinder body 5 is started so that the output end of the cylinder pushes the support frame 24, thereby driving the inner plate 23 to move right, thereby driving the bearing block 19 to move right, so that the roller 22 constantly contacts the bevel of the bearing block 19 and continues to roll until the roller 22 moves to the top of the bearing block. In this process, the lifting plate 4 will rise and squeeze the spring 3 at the same time. The spring 3 is compressed and stores elastic potential energy. At the same time, the movement of the lifting plate 4 will drive the top The plate 17 moves upward, thereby driving the upper mold 16 to be pulled out from the lower mold 14 to realize the opening of the mold.

When the upper mold 16 and the lower mold 14 are completely closed, the first sensing block 20 and the second sensing block 12 sense each other, and the indicator light 13 lights up, indicating that it is safe to pour. If the mold is not closed, the indicator light 13 does not light up, thereby preventing the occurrence of mis-pouring. The pillar 7, the guide rod 29, the guide hole 26 and the movable ball 27 and other components ensure that the lifting is safe.

What is particularly critical is that if the mold is not fully closed before pouring, the system often lacks an immediate and effective warning mechanism, which poses a potential threat to the safety of the operator and the quality of the cast product, and significantly increases the complexity and risk of the casting operation.
