Description

Technical Field

[0001] The utility model relates to the field of steel ingot moulds, and more specifically, to a double-opening oblate steel ingot mould. Background Art

[0002] Double-opening oblate ingot mold is a kind of ingot casting equipment used in steel mills, with a special structural design. Specifically, this mold is usually composed of two symmetrical semicircular molds, which can form a complete mold by closing the mold. This design makes the mold have high strength and stability, and can withstand large pressure and temperature changes, which is very important in the production process of steel ingots.

[0003] When the steel ingot mold is closed, the upper mold needs to be moved to the top of the lower mold through a hanging device, aligned, and then closed. The above alignment operation is relatively troublesome and requires multiple adjustments. Therefore, the linear maintenance components in the prior art (such as sliding sleeves and sliding rods) are often used during processing to maintain the relative linear movement of the upper and lower molds. Although the two do not need to be completely separated (always kept in a straight line), and thus no alignment operation is required, the linear maintenance components in the prior art are relatively long (after the product is injection molded, in order to facilitate the staff to take it out, the upper mold and the lower mold are generally separated by a long length to prevent obstruction, which requires a longer sliding rod to achieve this), which can easily cause obstruction to the normal operation of the double-open flat round steel ingot mold (for example, blocking the pouring device from moving the pouring port for pouring).

[0004] Therefore, in order to solve the above technical problems, the present application proposes a double-opening flat round steel ingot mold. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a double-opening oblate steel ingot mold.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-open flat round ingot mold, comprising an upper mold and a lower mold spliced ​​to each other, a pouring port being provided at the top of the upper mold, a straight line maintaining assembly being provided between the lower mold and the upper mold for maintaining the relative straight line movement of the two, the straight line maintaining assembly comprising two sliding rods fixed to the two sides of the lower mold respectively through a connecting plate A, and sliding sleeves are slidably connected to the outer side walls of the sliding rods, the surfaces of the sliding sleeves are fixed to the side walls of the upper mold through a connecting plate B, the interiors of the sliding rods are slidably connected to inner rods, and the inner rods pass through the openings at the heads of the sliding rods, and the heads of the inner rods are provided with blocking components for preventing the sliding sleeves from detaching from the sliding rods and the inner rods.

[0007] Preferably, guide rails are fixedly connected to the outer side walls of the slide rod, and the bottom ends of the inner rod are slidably connected to the guide rails via sliders to maintain the linear movement of the inner rod relative to the slide rod and prevent the inner rod from detaching from the slide rod.

[0008] Preferably, the blocking component includes an N-shaped plate fixed to the head of the inner rod, and a movable plate is slidably connected inside the N-shaped plate, side plates are welded on both sides of the movable plate, a through hole A is provided at the top of the N-shaped plate for the screw to pass through, and a screw hole is provided inside the movable plate for the screw to be installed, and the operation of the blocking component to perform blocking and contact blocking is very simple.

[0009] Preferably, a fixing component is installed between the upper mold and the lower mold.

[0010] Preferably, the fixing assembly includes a screw fixed to the top of the connecting plate A on both sides of the sliding rod, and both sides of the upper mold are fixedly connected to mounting plates on both sides of the connecting plate B. A through hole B is provided on the mounting plate for the screw to pass through, and a nut is threadedly connected to the outer wall of the screw.

[0011] Preferably, a frame-shaped plate is welded to the bottom of the upper mold, and a frame-shaped groove for inserting the frame-shaped plate is opened at the top of the lower mold, so as to improve the sealing performance of the connecting parts.

[0012] Preferably, hooks are provided at the top of the upper mold on both sides of the frame plate to facilitate the hanging device to lift the upper mold.

[0013] Preferably, the outer wall of the slide bar near the opening is in a slope shape that is inclined toward the middle part on all sides, so as to prevent the slide sleeve from getting stuck on the top of the slide when it contacts the slide sleeve downward.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The upper mold is moved downward by the hanging device, and the inner rod is not supported by the sliding sleeve to block the sliding sleeve, so that the sliding sleeve can slide onto the sliding rod again to connect the upper mold and the lower mold.

[0016] 2. The utility model pushes the movable plate to move rightward so that the side plate on the left side abuts against the N-shaped plate. At this time, the portion of the movable plate extending from the top surface of the inner rod can be used to block the sliding sleeve. At the same time, the screw hole on the movable plate is also aligned with the through hole on the N-shaped plate, so that the screw (large screw) can be passed through the through hole and then rotated clockwise to install it into the screw hole, thereby fixing the position of the movable plate. Similarly, remove the screw, push the movable plate to the left so that it does not protrude from the top surface of the inner rod, and then the sliding sleeve can be slid off the inner rod. The operation of blocking and contact blocking by the blocking component is very simple. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] like Figure 1-5 As shown, the utility model provides a double-open oblate steel ingot mold, including an upper mold 1 and a lower mold 2 spliced ​​to each other, a pouring port 9 is provided at the top of the upper mold 1, a straight line maintenance component 3 is provided between the lower mold 2 and the upper mold 1, for maintaining the relative straight line movement of the two, the straight line maintenance component 3 includes two slide bars 302 respectively fixed to the two sides of the lower mold 2 through a connecting plate A301, and the outer side walls of the slide bars 302 are slidably connected with a sliding sleeve 303, and the surface of the sliding sleeve 303 is connected by a connecting plate B3 04 is fixed to the side wall of the upper mold 1, the interior of the slide rod 302 is slidably connected with the inner rod 305, and the inner rod 305 passes through the opening at the head of the slide rod 302, and the head of the inner rod 305 is provided with a blocking component 4, which is used to prevent the sliding sleeve 303 from detaching from the slide rod 302 and the inner rod 305. The top of the upper mold 1 is located on both sides of the frame plate 6 and hooks 8 are provided. The outer side walls of the slide rod 302 are fixedly connected with guide rails 306, and the bottom ends of the inner rod 305 are slidably connected in the guide rails 306 through sliders 307.

[0025] When the upper mold 1 and the lower mold 2 are separated, the upper mold 1 can be lifted by acting on the hook 8 on the upper mold 1 through the hanging device, and the upper mold 1 drives the sliding sleeve 303 to move upward, and the sliding sleeve 303 slides upward along the sliding rod 302. When it exceeds the length of the sliding rod 302, the sliding rod 302 will drive the inner rod 305 to move upward, and the inner rod 305 extends from the sliding rod 302. The inner rod 305 drives the slider 307 to move upward, and the slider 307 slides along the guide rail 306 and blocks the top of the sliding sleeve 303 through the blocking component 4 to prevent the sliding sleeve 303 from separating from the sliding rod 302 and the inner rod 305, and the upper mold can be lifted. 1 and the lower mold 2 are separated by a long distance, so as to facilitate the removal of the steel ingot produced in the double-open flat round ingot mold. During processing, when the upper mold 1 is driven downward by the hanging device, the sliding sleeve 303 moves downward accordingly, and the inner rod 305 has no support for the blocking component 4 from the sliding sleeve 303. It will automatically move toward the inside of the sliding rod 302 due to gravity, so that the sliding sleeve 303 is slid onto the sliding rod 302 again to perform splicing between the upper mold 1 and the lower mold 2. This can not only maintain the relative linear movement between the upper mold 1 and the lower mold 2, but also reduce the length of the linear maintaining component (that is, the length of the sliding rod 302).

[0026] Furthermore, the outer wall of the slide rod 302 near the opening is in a slope shape that is inclined toward the middle part. This can prevent the slide sleeve 303 from getting stuck on the top of the slide sleeve 303 when it contacts the slide sleeve 303 downward, making the operation more convenient.

[0027] A fixing component 5 is also installed between the upper mold 1 and the lower mold 2. The fixing component 5 includes a screw 501 fixed on the top of the connecting plate A301 and located on both sides of the sliding rod 302. Both sides of the upper mold 1 are fixedly connected with mounting plates 502 on both sides of the connecting plate B304. The mounting plate 502 is provided with a through hole B503 for the screw 501 to pass through. A nut is threadedly connected to the outer wall of the screw 501. A frame plate 6 is welded to the bottom of the upper mold 1, and a frame groove 7 is provided at the top of the lower mold 2 for the frame plate 6 to be inserted into.

[0028] When the upper mold 1 and the lower mold 2 are pressed against each other for mold closing, the frame plate 6 below the upper mold 1 is also inserted into the frame groove 7. Through the concave-convex structure, the contact area between the upper mold 1 and the lower mold 2 is increased, so that the sealing of the connection is better. When the two are pressed against each other, the screw 501 on the connecting plate A301 also passes through the through hole on the mounting plate 502. Then, the nut is installed on the screw 501 by turning the nut clockwise. The nut moves downward along the screw 501 and slowly rests against the top of the mounting plate 502 to fix the upper mold 1 and the lower mold 2, making the connection between the two more secure. After the mold closing is completed, the injection molding solution can be poured into the double-open flat round ingot mold through the pouring port 9 to manufacture the ingot.

[0029] The following is a specific structure of the blocking component 4, which includes an N-shaped plate 401 fixed to the head of the inner rod 305, and a movable plate 402 is slidably connected inside the N-shaped plate 401, and side plates 403 are welded on both sides of the movable plate 402. A through hole A404 is provided at the top of the N-shaped plate 401 for screws to pass through, and a screw hole 405 is provided inside the movable plate 402 for screw installation, that is, the movable plate 402 is pushed to move rightward, so that the side plate 403 on the left side abuts against the N-shaped plate 401, and at this time, the portion of the movable plate 402 extending from the top surface of the inner rod 305 can be used to block the sliding sleeve 30 3. At the same time, the screw hole 405 on the movable plate 402 is also aligned with the through hole on the N-shaped plate 401, and the screw (large screw) can be passed through the through hole and then rotated clockwise to install it into the screw hole 405, thereby fixing the position of the movable plate 402. Similarly, remove the screw and push the movable plate 402 to the left so that it does not protrude from the top surface of the inner rod 305, and then the sliding sleeve 303 can be slid off the inner rod 305. In this way, when damage occurs between the upper mold 1 and the lower mold 2, they can be disassembled and replaced. In summary, the operation of blocking and contact blocking by the blocking component 4 is very simple.
