Description

Technical Field

[0001] This utility model relates to the field of steel ingot molds, and more specifically, it relates to a steel ingot mold with an adjustable cavity size. Background Technology

[0002] In the steel smelting and processing industry, steel ingot molds are key equipment that determines the specifications and quality of steel ingots. Traditional steel ingot molds generally adopt a fixed cavity structure, and the length, width, height, and other dimensions of the cavity are determined during mold manufacturing, which cannot be adjusted according to actual needs during production. When it is necessary to produce steel ingots of different specifications (such as rectangular ingots, round ingots, or special-shaped ingots with different cross-sectional dimensions), corresponding special molds must be used.

[0003] This necessitates that companies equip each steel ingot specification with a separate mold, resulting in a wide variety of molds. According to industry statistics, medium-sized steel companies typically have more than 50 types of steel ingot molds in stock, leading to high warehousing space occupancy and high mold management costs.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a steel ingot mold with adjustable cavity size. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel ingot mold with an adjustable cavity size.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel ingot mold with adjustable cavity size, comprising a mold body, wherein a mold cavity is provided inside the mold body, and movable plates are provided on both sides inside the mold cavity. A sealing element is provided between the movable plate and the mold cavity, and the sealing element is used to realize the movable sealing connection between the movable plate and the mold cavity. An adjustment mechanism is also provided on both sides of the mold body to drive the movable plate to move along a direction perpendicular to the mold cavity opening and fix its position after movement.

[0007] Preferably, the seal includes a sealing strip surrounding the edge of the movable plate.

[0008] Preferably, the mold body has circular through slots on both sides that communicate with the mold cavity. The adjustment mechanism includes a connecting rod that passes through the circular through slot and is connected to the movable plate, and a screw fixed on both sides of the mold cavity. The other end of the connecting rod is fixedly connected to an adjustment plate. The adjustment plate has through holes for the screw to pass through. Nuts are threadedly connected to the outer side wall of the screw on both the upper and lower sides of the adjustment plate.

[0009] Preferably, guide rails are fixedly connected to both sides of the mold body on the upper and lower sides of the adjustment plate, and the upper and lower sides of the adjustment plate are slidably connected to the guide rails by sliders.

[0010] Preferably, a scale is fixedly connected to the surface of the mold body, and the side end of the adjustment plate is connected to the indicator arrow through the connecting plate A, with the indicator arrow pointing at a position opposite to the scale on the scale.

[0011] Preferably, a rubber pad is provided at the bottom of the mold body.

[0012] Preferably, the back of the mold body is connected to the injection funnel directly above the mold cavity opening via a connecting plate B.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model allows for the adjustment of the mold cavity size by moving and fixing the movable plate without changing the mold, enabling the production of steel ingots of various specifications from a single mold. This effectively solves the problems of frequent mold changes, high inventory pressure, and high mold management costs associated with traditional fixed-cavity molds.

[0015] 2. This utility model can effectively constrain the movable plate to move only in the direction perpendicular to the mold cavity opening by limiting the guide rail and slider, effectively preventing tilting or deflection caused by unilateral force during the adjustment process, avoiding the shear force generated by the movable plate offset on the sealing element, and improving the reliability of dynamic sealing.

[0016] 3. With this utility model, operators can align the indicator arrow with the target scale in real time, quickly determine the position of the movable plate without the need for additional measuring tools, and significantly improve operating efficiency. Attached Figure Description

[0025] like Figure 1-5 As shown, this utility model provides a steel ingot mold with adjustable cavity size, including a mold body 1, a mold cavity 101 inside the mold body 1, movable plates 2 on both sides inside the mold cavity 101, a sealing element 3 between the movable plates 2 and the mold cavity 101, the sealing element 3 is used to realize the movable sealing connection between the movable plates 2 and the mold cavity 101, and an adjustment mechanism 4 is also provided on both sides of the mold body 1 to drive the movable plates 2 to move in a direction perpendicular to the opening of the mold cavity 101 and fix their positions after movement.

[0026] Movable plates 2 are installed on both sides of the mold cavity 101 inside the mold body 1. The movable plates 2 and the mold cavity 101 are connected to each other by a sealing element 3 to ensure the sealing during steel pouring and to not affect the movement of the movable plates 2. When it is necessary to adjust the size of the mold cavity 101, the adjustment mechanism 4 on both sides of the mold body 1 drives the movable plates 2 to move in a direction perpendicular to the opening of the mold cavity 101. The position of the movable plates 2 is adjusted by the precise control of the adjustment mechanism 4 until the size of the mold cavity 101 meets the target steel ingot specifications. Then the adjustment mechanism 4 fixes the position of the movable plates 2 to ensure the stability of the size of the mold cavity 101 during the pouring process. Thus, without changing the mold, the size of the mold cavity 101 can be adjusted by moving and fixing the movable plates 2, so as to realize the production of steel ingots of multiple specifications by a single mold.

[0027] The sealing element 3 includes a sealing strip surrounding the edge of the movable plate 2. The sealing strip is made of graphite-reinforced high-temperature resistant rubber, which is the optimal solution based on the high temperature and dynamic adjustment conditions of the steel ingot mold. Its material properties perfectly balance high temperature resistance, sealing performance, wear resistance and economy, ensuring that the movable plate 2 achieves reliable dynamic sealing during the adjustment process. Moreover, the back of the mold body 1 is connected to the injection funnel 7 directly above the opening of the mold cavity 101 through the connecting plate B6. Through the drainage of the injection funnel 7, it is ensured that the molten steel injection path is always vertically aligned with the center of the mold cavity 101 and located between the two movable plates 2. At the same time, the present invention provides a rubber pad 5 at the bottom of the mold body 1. The rubber pad 5 utilizes its elastic deformation to effectively cushion the impact when the mold body 1 is lowered to the ground by the hoisting equipment, so as to avoid damage to the bottom of the mold body 1.

[0028] This utility model also provides a specific structure of the adjustment mechanism 4: the mold body 1 has circular through slots 102 on both sides that communicate with the mold cavity 101. The adjustment mechanism 4 includes a connecting rod 401 that passes through the circular through slot 102 and is connected to the movable plate 2, and a screw 403 that is fixed on both sides of the mold cavity 101. The other end of the connecting rod 401 is fixedly connected to the adjustment plate 402. The adjustment plate 402 has through holes 404 for the screw 403 to pass through. Nuts 405 are threadedly connected to the outer side of the screw 403 on both the upper and lower sides of the adjustment plate 402.

[0029] The circular through slots 102 on both sides of the mold body 1 provide through channels for the connecting rod 401, so that one end of the connecting rod 401 is fixedly connected to the movable plate 2 and the other end is connected to the adjusting plate 402, forming a transmission connection between the movable plate 2 and the external adjusting components; the screw 403 is fixed on both sides of the mold cavity 101, and the adjusting plate 402 is sleeved on the outside of the screw 403 through the through hole 404. The nuts 405 at the upper and lower ends are connected to the screw 403 through threads. When adjusting the size of the mold cavity 101, first loosen the upper and lower nuts 405. Nut 405 pushes adjusting plate 402 along screw 403, and drives movable plate 2 to move along circular through groove 102, i.e., perpendicular to the opening of mold cavity 101, through connecting rod 401, until the size of mold cavity 101 meets the target specifications; then tighten the upper and lower nuts 405, and fix movable plate 2 by clamping force between nuts 405 and adjusting plate 402, so that the rigid support of screw 403 and locking force of nuts 405 work together to prevent movable plate 2 from displacing due to force during molten steel pouring.

[0030] Furthermore, guide rails 406 are fixedly connected to both sides of the mold body 1, located on the upper and lower sides of the adjusting plate 402. Both sides of the adjusting plate 402 are slidably connected to the guide rails 406 via sliders 407. That is, when the adjusting plate 402 moves back and forth, it drives the sliders 407 to move. The sliders 407 slide along the guide rails 406 to maintain the linear movement of the adjusting plate 402, thereby maintaining the linear movement of the movable plate 2. This effectively constrains the movable plate 2 to move only in a direction perpendicular to the opening of the mold cavity 101, effectively preventing tilting or deflection caused by unilateral force during adjustment, and avoiding the movable plate 2 shifting and causing damage to the sealing element 3. The shear force is generated, improving the reliability of dynamic sealing. Moreover, a scale 408 is fixedly connected to the surface of the mold body 1. The side end of the adjusting plate 402 is connected to the indicator arrow 410 through the connecting plate A409. The indicated position of the indicator arrow 410 is opposite to the scale on the scale 408. When the adjusting plate 402 moves to adjust the position of the movable plate 2, the adjusting plate 402 also drives the connecting plate A409 to move along the scale 408. The operator can use the indicator arrow 410 to align with the target scale on the scale 408 in real time, and can quickly determine the position of the movable plate 2 without the need for additional measuring tools, which significantly improves the operating efficiency.
