[0001] The utility model relates to the technical field of sand molds, and particularly relates to a sand mold mold closing device. Background Art
[0002] The processing steps of an anchor include casting, cutting and grinding, welding, galvanizing and painting, etc. Among them, the casting process usually uses a sand mold as the casting cavity. The sand mold is made of raw sand, binder and other auxiliary materials, and has the advantages of low cost and easy availability of materials, and simple manufacture of the mold.
[0003] In the prior art, due to the large volume and weight of the sand mold for anchor casting, the mold closing is usually carried out by means of hoisting. However, due to the instability of the lifting chain, it is easy to shake when lowering, and collisions will occur if the operation is improper, resulting in fracture and damage of the sand mold. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a sand mold mold closing device, which can improve the stability during mold closing.

[0007] The lifting mechanism includes an annular frame, sliders and suspension ropes. The annular frame is arranged on the sliding base. A plurality of the sliders are arranged on the annular frame around the circumference of the annular frame. Winches are arranged on the sliders, suspension ropes are arranged on the winches, and one ends of the plurality of suspension ropes far away from the winches are connected to each other through suspension rings.
[0008] After fixing the upper sand mold with the suspension ring, a plurality of winches are started simultaneously to lift the suspension ropes, so as to lift the upper sand mold. By moving the gantry on the site track and moving the sliding base on the gantry, the upper sand mold is moved above the lower sand mold, and then a plurality of winches lower the suspension ropes simultaneously, so as to close the upper sand mold and the lower sand mold.
[0009] The beneficial effect of the above sand mold mold closing device is that the use of suspension ropes in multiple directions connected to the suspension rings can improve the stability of the upper mold during movement and lifting, and no shaking will occur, thus avoiding the situation that the upper mold is damaged due to shaking during movement or lifting.
[0010] Further, a plurality of the sliders are slidably sleeved on the annular frame. An active gear and a fixed gear ring are further provided on the sliding base. The active gear is rotatably arranged at the center of the annular frame and is connected to a driving source. The fixed gear ring is arranged on the outer side of the annular frame. Driven gears are rotatably connected to the sliders, and both sides of each driven gear are meshed with the active gear and the fixed gear ring respectively.
[0011] By driving the active gear to rotate through the driving source, the driven gears can be driven to rotate, so that the driven gears and the sliders revolve relative to the active gear and the fixed gear ring. After a plurality of sliders move circumferentially at the same time, the hanging rope and the sand mold upper mold fixed by the hanging ring can be rotated, so as to adjust the direction of the sand mold upper mold and facilitate the mold closing with the sand mold lower mold.
[0012] Further, the annular frame is an endless circular track rod, and the cross section of the track rod is rectangular.

[0014] Further, a connecting rod is provided on the annular frame and is connected to the sliding base through the connecting rod. An arc-shaped groove for slidably connecting with the connecting rod is formed in the slider.
[0015] When the slider moves on the annular frame, the arc-shaped groove can be used to pass through the connecting rod to avoid interference, thereby increasing the moving range of the slider on the annular frame and making it more convenient to adjust the direction of the upper mold.
[0016] Further, an arc-shaped chute is formed in the slider. The chute is slidably connected to the annular frame and is communicated with the arc-shaped groove. The slider wraps around the annular frame.
[0017] The slider slides on the annular frame through the chute, and the arc-shaped groove can avoid interfering with the connecting rod. The slider wraps around the annular frame, which can improve the stability of movement and prevent falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.
[0026] Please refer to Figures 1 to 3 , the present invention provides a sand mold clamping device, including a gantry 10 and a lifting mechanism 20. The gantry 10 is used for the horizontal and vertical movement of the upper sand mold, and the lifting mechanism 20 is used for the vertical movement of the upper sand mold.
[0027] Specifically, both ends of the gantry 10 are movably arranged on the site track, and a movable sliding base 11 is arranged at the top. The lifting mechanism 20 includes an annular frame 21, sliders 22 and lifting ropes 23. The annular frame 21 is arranged at the bottom of the sliding base 11. A plurality of sliders 22 are arranged on the annular frame 21 at equal intervals around the circumference of the annular frame 21. Winches 24 are arranged at the bottoms of the sliders 22, and lifting ropes 23 are arranged on the winches 24. One ends of the plurality of lifting ropes 23 away from the winches 24 are connected to each other through lifting rings 231, and the lifting rings 231 are used to fix the upper sand mold.
[0028] After fixing the upper sand mold with the lifting rings 231, a plurality of winches 24 are started simultaneously to lift the lifting ropes 23, and then the upper sand mold can be lifted. By moving the gantry 10 on the site track and the sliding base 11 on the gantry 10, the upper sand mold is moved above the lower sand mold. Subsequently, a plurality of winches 24 lower the lifting ropes 23 simultaneously, and then the upper sand mold and the lower sand mold can be clamped. The plurality of lifting ropes 23 pull the lifting rings 231 from multiple directions, which can improve the stability during movement and lifting to avoid shaking and collision.
[0029] Specifically, multiple sliders 22 are slidably sleeved on the annular frame 21 in a movable manner. An active gear 25 and a fixed gear ring 26 are further provided on the sliding base 11. The active gear 25 is rotatably arranged at the center of the annular frame 21 and is connected to a drive source. In this embodiment, the drive source is a motor 251, which is fixedly arranged at the bottom of the sliding base 11 and connected to the active gear 25. The fixed gear ring 26 is fixedly arranged on the outer side of the annular frame 21. Rotatable driven gears 27 are provided on the sliders 22. The two sides of the driven gear 27 are respectively meshed with the outer ring of the active gear 25 and the inner ring of the fixed gear ring 26.
[0030] By driving the active gear 25 to rotate through the motor 251, the driven gear 27 can be driven to rotate, so that the driven gear 27 drives the slider 22 to revolve relative to the active gear 25 and the fixed gear ring 26. The lifting ring 231 is located at the center among the multiple lifting ropes 23. Therefore, after the multiple sliders 22 move circumferentially at the same time, the fixed upper sand mold can be rotated to adjust the direction of the upper sand mold, which is convenient for closing the mold with the lower sand mold.
[0031] Specifically, the annular frame 21 is an endless circular track rod, and the cross-section of the track rod is rectangular. An arc-shaped chute 221 is formed inside the slider 22 and wraps around the annular frame 21. The cross-section of the chute 221 is also rectangular and is slidably connected to the annular frame 21, so as to have better stability during movement and can avoid falling and shaking. A connecting rod 211 is provided on the annular frame 21 and is connected to the sliding base 11 through the connecting rod 211. An arc-shaped groove 222 slidably connected to the connecting rod 211 is formed on the slider 22. The chute 221 is communicated with the arc-shaped groove 222. When the slider 22 moves on the annular frame 21, the arc-shaped groove 222 can be used to pass through the connecting rod 211 to avoid interference, thereby increasing the movement range of the slider on the annular frame and making it more convenient to adjust the direction of the upper mold.
[0032] The working principle of the above sand mold closing device is as follows: After the lifting ring 231 is fixedly connected to the upper sand mold, multiple winches 24 are started simultaneously to lift the lifting ropes 23, and then the upper sand mold can be lifted. It is moved on the site track through the gantry 10, and the sliding base 11 moves on the gantry 10 to move the upper sand mold above the lower sand mold. Subsequently, multiple winches 24 lower the lifting ropes 23 simultaneously, and then the upper sand mold can be closed with the lower sand mold. If it is necessary to adjust the direction of the upper sand mold, the motor 251 can be used to drive the active gear 25 to rotate, and the driven gear 27 drives the slider 22 to move circumferentially on the annular frame 21, so that the upper sand mold rotates to adjust the direction.
[0033] Using the above sand mold clamping device, by connecting the lifting ropes in multiple directions with the lifting rings, the stability of the upper mold during movement and lifting can be improved, and there will be no shaking, thus avoiding the situation that the upper mold is damaged due to shaking during movement or lifting. Moreover, the rotation direction is also rotated by the movement of multiple sliders at the top, without the need for personnel to rotate it manually at the bottom, further reducing the risk.
[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
