Description

Technical Field

[0001] The utility model relates to the technical field of production molds for skateboard bricks used for steel casting, and is specifically a floating device for forming a skateboard with a groove. Background Art

[0002] Sliding nozzle is an important functional refractory material, and its quality affects the casting process of steel mills, among which the sliding plate brick is a key component. The volume density of the sliding plate brick affects the use effect. A large volume density is likely to weaken the thermal shock resistance, while a small volume density may cause a decrease in strength, and a decrease in erosion and corrosion resistance. Too large or too small a volume density will reduce the use effect of the sliding plate and reduce the service life of the sliding plate. Therefore, it is hoped that the volume density of the sliding plate brick is stable.

[0003] Some skateboard bricks are designed with groove structures around the casting holes, some are made into inlaid skateboards, and after forming, inlaid rings made of highly erosion-resistant materials (such as zirconium oxide) are inlaid in the groove structure, and some are designed as groove interfaces, which are used in conjunction with nozzles designed as bosses. When forming this skateboard brick, due to the existence of the groove structure, the thickness of the skateboard is inconsistent. In order to make the volume density of the skateboard consistent in various parts as much as possible, the material in the groove part should be less than that in other parts. At present, this kind of material distribution requires manual operation by workers, which has low labor efficiency on the one hand, and many human factors on the other hand, which is prone to quality fluctuations.

[0008] Furthermore, the groove mold and the floating block have the same shape and size.

[0009] Furthermore, the floating device for forming a grooved skateboard also includes a mold core, and the centers of the groove mold and the floating block are provided with through holes adapted to the mold core, and the mold core is vertically inserted into the bottom surface of the floating groove when in use.

[0010] Furthermore, the upper end of the support member is fixed to the bottom surface of the floating block, or the lower end of the support member is fixed to the bottom surface of the floating groove.

[0011] Furthermore, the number of the supporting members is one or more.

[0016] Furthermore, the plastic support member is detachably connected to the floating groove or the floating block.

[0017] The technical solution of the utility model has achieved the following beneficial technical effects:

[0018] The utility model is simple and easy to operate. When filling refractory mud, less material is distributed in the groove structure position through the occupying effect of the floating block, thereby improving the material distribution efficiency of the slide plate. When the brick press is forming, the groove mold and the floating block move down at the same time, which can keep the compression ratio of the groove structure basically consistent with other parts, and can improve the uniformity of the density of the refractory material of the slide plate, improve the forming efficiency of the slide plate, and at the same time improve the quality stability of the slide plate bricks.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] like Figures 1 to 7As shown, a floating device for forming a grooved skateboard includes a base plate 6, a floating block 5, a groove mold 1 and a support member 4, wherein the base plate 6 refers to the base plate 6 of the molding mold for the refractory mud material 3, and the lower surface of the base plate 6 is provided with a floating groove, and the floating groove and the floating block 5 are arranged at positions corresponding to the groove structure in the molding mold base plate 6; the top of the floating groove is open, and a support member 4 whose height can be reduced under pressure is provided on the bottom surface of the floating groove, and the upper end of the support member 4 supports the floating block 5, and the floating block 5 is slidably connected in the floating groove, and the peripheral wall of the floating block 5 is in sliding contact with the inner wall of the floating groove, and the loaded refractory mud material 3 will not enter the floating groove along the gap between the floating block 5 and the inner wall of the floating groove, and the upper surface of the floating block 5 remains parallel to the upper surface of the base plate 6; the groove mold 1 is used in conjunction with the floating block 5.

[0029] like Figures 1 to 6 As shown, the thickness of the groove mold 1 is h, and the floating block 5 has the highest initial position and the lowest position after being pressed; when the floating block 5 is in the initial position, the distance that the floating block 5 protrudes from the upper surface of the bottom plate 6 is D, and D ≥ h; when the floating block 5 is in the lowest position, the upper surface of the floating block 5 is flush with the upper surface of the bottom plate 6; Figure 1 , Figure 3 , Figure 5 and Figure 7 : is a schematic diagram of the state when the floating block 5 is in the initial position, Figure 2 , Figure 4 , Figure 6 The middle is a schematic diagram of the state when the floating block 5 is at the lowest position.

[0030] When the brick press is forming, the floating block 5 and the support member 4 are placed in the floating groove, and then the refractory mud 3 is filled. Due to the supporting force of the support member 4, the floating forming block is higher than the height D of the bottom plate 6; the upper surface of the refractory mud 3 is roughly flattened, and then the groove mold 1 is placed, and then pressing is carried out; after the refractory mud 3 is compressed, strength will be generated. During the pressing process, the groove mold 1 is immersed in the refractory mud 3, and at the same time, the pressure of the hammer head will be transmitted to the floating block 5 through the compressed refractory mud 3, and then transmitted to the spring or hydraulic push rod, so that the support member 4 will shrink, the height of the support member 4 will become smaller, and the floating block 5 will move down; at the end of pressing, the floating block 5 is in the lowest position, and the upper surface of the floating block 5 will be flush with the bottom plate 6; then the mold is removed, and the groove mold 1 is removed to obtain a skateboard with a groove structure; the utility model well solves the problem of manual material laying during the forming of the skateboard with grooves, and the workers can easily grasp the material laying thickness at the groove structure, so that the forming efficiency of the skateboard with grooves is improved.

[0031] like Figures 1 to 6As shown, preferably, the groove mold 1 and the floating block 5 have the same shape and size. Since the size and shape of the groove structure are determined by the groove mold 1, when there is a size difference between the groove mold 1 and the floating block 5, the area of ​​the difference may cause the compression ratio of the refractory mud 3 to be inconsistent with the compression ratio of other positions. This situation can only be avoided when the shapes and sizes of the groove mold 1 and the floating block 5 are exactly the same.

[0032] like Figures 1 to 6 As shown, the floating device for forming a grooved skateboard also includes a core 2, which is used to form a flow hole for molten steel. The centers of the groove mold 1 and the floating block 5 are provided with through holes adapted to the core 2, and the bottom of the floating groove begins to have a socket matching the core 2. The core 2 is vertically inserted into the socket of the floating groove when in use.

[0033] like Figures 1 to 6 As shown, one end of the support member 4 is fixed. Specifically, the upper end of the support member 4 is fixed to the bottom surface of the floating block 5, or the lower end of the support member 4 is fixed to the bottom surface of the floating groove. The support member 4 fixed at one end facilitates the disassembly of the floating block 5, and the support member 4 can be fixed by welding, gluing or bolting.

[0034] like Figures 1 to 6 As shown, the number of the support members 4 is one or more; the floating groove is a vertically opened straight groove, and the sliding connection between the peripheral wall of the floating block 5 and the inner wall of the floating groove can ensure that the surface of the floating block 5 remains parallel to the upper surface of the ground. Therefore, there is no strict requirement on the number of the support members 4. When the number of the support members 4 is one, the support member 4 can have a central through hole and be arranged at the center of the floating groove, and the core 2 passes through the central through hole, or it can be arranged at any position in the floating groove; preferably, the support members 4 are multiple and evenly distributed in the center of the floating block 5.

[0035] The method of the present invention solves the molding problem of the grooved slide plate very well. When the brick press is molding, the floating device is placed in the floating groove in the bottom plate 6. Due to the use of this device, after the mud is poured into the molding mold, the initial accumulation thickness of the mud is H1, the thickness of the groove structure is (groove mold 1) h, the mud at the groove structure position is less than other parts, and after molding, the final thickness of the slide plate is H2, and the compression ratio of the groove part is basically consistent with that of other parts. The initial height of the floating block 5 is higher than the bottom plate 6 by a distance D, and the support member 4 can be designed according to the value of D; if the compression of the refractory mud 3 is ignored, then D should be equal to h in theory, but in practice the refractory mud 3 will be compressed after being pressed. If the compression of the refractory mud 3 after the groove mold 1 is placed on the top of the refractory mud 3 is ignored, and the compression of the floating block 5 by the gravity of the refractory mud 3 and the groove mold 1 is ignored, then D should be greater than h.

[0036] Specifically, in one embodiment, the support member 4 is elastic, and the support member 4 can be restored to its original height after the external force is removed. Any elastic member or telescopic member that meets the above conditions in the prior art can be used as the support member. Preferably, the support member 4 is a compression spring, a rubber spring, a plastic spring, a ceramic spring, a carbon nanotube spring, a V-shaped spring, a rubber block, a gas spring or a hydraulic push rod; Figure 1-Figure 2 The middle is a schematic diagram of the state when the support member 4 is a compression spring, Figure 3-4 The middle diagram is a state diagram when the support member 4 is a gas spring or a hydraulic push rod; after the slide plate is ejected from the mold, the floating block 5 is pushed up by the elastic support member 4 and returns to the initial position, so that the next loading of the refractory mud 3 can continue.

[0037] In another embodiment, Figure 5-Figure 6 As shown, the support member 4 includes a plastic support member and a height-fixing support member, the initial height of the plastic support member is higher than the height of the height-fixing support member, and the floating block 5 is pushed to the initial position. After pressing, the plastic support member is bent, compressed or broken after being pressed, resulting in a decrease in height, and the floating block 5 moves downward until the lower surface of the floating block 5 is against the upper surface of the height-fixing support member, at which time the floating block 5 reaches the lowest position; the plastic support member is supported by materials in the prior art, such as hard metal sheets / metal cylinders, rubber blocks / rubber cylinders, wooden blocks, etc. that are bent / bent or have bending guide marks; the plastic support member is detachably connected to the floating groove or the floating block; in this embodiment, since the plastic support member cannot rebound, before the next loading of the refractory mud 3, it is necessary to pick up the floating block 5 to replace the support member 4 or the plastic support member, such as the plastic support member can be set through a common base, and the bottom surface of the common base has a certain area, and the plastic support member and the height-fixing support member connected to the common base and fixed thereon can be directly placed in the floating groove.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
