Description

Technical Field

[0001] The invention relates to the technical field of mold spraying, and in particular to a mold spraying device and a spraying method for refractory materials. Background Art

[0002] Refractory materials require refractory molds when they are processed and formed, and existing refractory molds require carbide coatings or other coatings to be sprayed on the outside during production and processing to ensure the use effect and service life of the molds.

[0003] In the prior art, when spraying a mold for refractory materials, it is generally clamped and fixed by a clamp or placed in a placement groove to limit its position, and then a nozzle is used to spray it. However, the method of controlling the clamp to clamp the mold or accurately placing the mold in the placement groove is relatively cumbersome to operate. At the same time, when it is limited by the clamp or the placement groove, the clamp or the inner wall of the groove will contact and cover the outer side of the mold, thereby making it impossible for the nozzle to spray the blocked area of ​​the mold and unable to spray the mold surface in all directions. The staff needs to adjust the position of the mold and change the contact position between the mold and the clamp or the inner wall of the groove, so as to realize the spraying work of the previously blocked position. The secondary clamping can realize the comprehensive spraying of the mold, resulting in low efficiency of mold spraying. Summary of the invention

[0010] Preferably, the connecting seat and the support are arranged obliquely, and the connecting seat is arranged parallel to the mold body placed on the movable base.

[0011] Preferably, the pushing and flipping assembly comprises a side plate fixedly connected to the connecting seat, an electric telescopic rod is fixedly provided on the side plate, and a push rod that movably abuts against the mold body is fixedly provided at one end of the electric telescopic rod away from the side plate.

[0012] Preferably, support plates are fixedly provided on both sides of the movable base, each of the support plates is connected to an elastic telescopic rod, and the ends of the elastic telescopic rods are connected to abutment plates that movably abut against the mold body.

[0013] Preferably, both the front and rear sides of the movable base are rotatably connected with a rotating shaft, each end of the rotating shaft is provided with a walking wheel, a driven bevel gear is provided on the rotating shaft, and the bottom end of the reciprocating screw is fixed with an active bevel gear meshing with the driven bevel gear.

[0014] The present invention also discloses a method for spraying a mold for a refractory material, which uses the above-mentioned mold spraying device for a refractory material for spraying, and comprises the following steps: S1: Place multiple mold bodies to be sprayed on a support table, and make one side of the mold body abut against the side support plate of the support seat. The mold body is placed on the movable base at an angle, and the limit strip on the base limits the lower side of the mold body. The side of the mold body that is tilted upward is not blocked by other components. S2: Then, the driving motor of the spraying part is controlled to operate. When the driving motor operates, the reciprocating screw is driven to rotate. The sleeve threadedly connected to the reciprocating screw drives the nozzle to move along the axial direction of the reciprocating screw through the connecting plate, so that the nozzle sprays the inclined mold body from top to bottom. When the sleeve drives the nozzle to move along the connection seat through the connection plate, the nozzle intermittently abuts against the convex block on the side of the connection seat. When the nozzle abuts against the convex block, the nozzle is subjected to force and swings around the pin shaft. When the nozzle does not abut against the convex block, the nozzle is no longer subjected to force and will reset and rotate under the action of the torsion spring, so that the nozzle swings left and right when spraying the mold body, and then the nozzle sprays the two sides of the mold body. When the reciprocating screw rotates, it will also drive the input shaft of the gear box to rotate. Through the gear transmission inside the gear box, the gear box converts the high-speed rotation of its input shaft into the low-speed rotation of its output shaft. The driving gear of the output shaft of the gear box meshes with the rack plate for transmission, so that the movable base drives the mold body placed on the upper side to move slowly, so that the nozzle sprays the mold body placed on the movable base in turn; S3: With the movement of the mobile base, the mold body being sprayed moves away from the spraying part that has completed the spraying work on it. After the mold body that has completed the spraying on one side moves between the two spraying parts, the electric telescopic rod is controlled to work, and the electric telescopic rod is stretched and pushes the tilted mold body through the push rod, so that the mold body is turned over under the limit of the limit bar at its bottom, and the mold body is gradually turned from the tilted state to the vertical state and abuts with the abutment plate at the end of the elastic telescopic rod. With the continued pushing of the push rod, the mold body is transformed from the vertical state to the tilted state again, and the mold body pushed by the push rod to tilt exerts a force on the abutment plate, and the elastic telescopic rod gradually contracts, so that the mold body pushed by the push rod to tilt slowly drops to the side support plate on the other side; S4: With the continuous movement of the movable base, the mold body that has completed the flipping work moves to another spraying part, and the other spraying part repeats the operation steps of S2 to spray the upper side of the flipped mold body, thereby achieving comprehensive spraying of the mold body.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The refractory mold spraying device and spraying method tilt the mold body on a movable base so that the side of the mold body facing upward to be sprayed is not blocked by other parts. When the spraying work on one side of the mold body is completed, the mold body is pushed to flip over, so that the other side of the mold body is sprayed, thereby achieving comprehensive spraying of the mold, replacing the complex spraying method of secondary clamping in the prior art of clamping the mold by controlling the fixture or accurately placing the mold in the placement groove, reducing the difficulty of spraying work for the staff and improving the efficiency of mold spraying; 2. The mold spraying device and method for refractory materials drive the reciprocating screw to rotate by driving a motor, so that the sleeve threadedly connected to the reciprocating screw drives the nozzle to move along the axial direction of the reciprocating screw through the connecting plate, so that the nozzle sprays the inclined mold body from top to bottom, and the reciprocating screw rotates and the input shaft of the gear box is driven to rotate at the same time. Through the gear transmission in the gear box, the gear box converts the high-speed rotation of its input shaft into the low-speed rotation of its output shaft. The driving gear of the output shaft of the gear box meshes with the rack plate for transmission, so that the movable base drives the mold body placed on the upper side to move slowly, so that the nozzle sprays the upper side of the mold body in turn, and the nozzle moves up and down to spray and the mold moves horizontally at the same time, so that the above components act as a linkage mechanism for continuous action, so that the various components cooperate and relate to each other to achieve coordinated movement, so that the mold spraying action is more coherent and smooth, and the mold spraying effect and spraying efficiency are guaranteed; 3. The refractory mold spraying device and spraying method, when the mold body is gradually turned from an inclined state to a vertical state, the mold body will abut against the abutment plate at the end of the elastic telescopic rod. When the mold body continues to be pushed by the push rod on one side, the mold body that is turned over and tilted again will press against the abutment plate, so that the elastic telescopic rod is compressed, so that the mold body that is pushed and tilted by the push rod is slowly lowered to the side support plate on the other side, so as to avoid the mold body that is pushed and turned over by the push rod directly dumping on the side support plate, so that the mold body and the side support plate collide greatly, causing damage to the coating sprayed on the surface of the mold body; 4. The refractory material mold spraying device and spraying method are configured such that the connecting seat and the support are tilted, and the connecting seat is parallel to the mold body placed on the movable base, so that when the nozzle moves up and down along the connecting seat to spray the mold body, the nozzle always maintains the same distance from the mold body when moving up and down, so that the nozzle has the same spraying distance at each position of the tilted mold, thereby improving the uniformity of the nozzle spraying on the mold and ensuring the spraying effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] Example 1: Reference Figure 1-8 , a refractory mold spraying device, comprising a workbench 1, and also comprising: A movable base 2, the movable base 2 slides on the workbench 1 and is used to transport the mold body 3; A support platform 4, wherein the support platform 4 is fixed on the mobile base 2, and support seats 5 are provided on both sides of the support platform 4, and each of the support seats 5 includes a support rod 501 fixed on the mobile base 2 and a side support plate 502 fixedly connected to the support rod 501; A spraying unit, wherein the spraying unit is provided in two groups and is staggeredly arranged on both sides of the workbench 1; The spraying part is connected with a pushing and flipping assembly that is movably opposed to the mold body 3, and the pushing and flipping assembly is placed between the two groups of spraying parts.

[0021] Furthermore, the support platform 4 includes a base 401 and limiting bars 402 fixed on both sides of the base 401 , and the two limiting bars 402 are movably opposed to the mold body 3 .

[0022] Specifically, multiple mold bodies 3 to be sprayed are placed on the support platform 4, so that one side of the mold body 3 is in contact with the side support plate 502 of the support seat 5, and the mold body 3 is tilted on the movable base 2. The limit strip 402 on the base 401 limits the lower side of the mold body 3, and the upward tilted side of the mold body 3 is not blocked by other components. After the spraying work on one side of the mold body 3 is completed, the mold body 3 is pushed and turned over, so that the other side of the mold body 3 is sprayed, thereby realizing the comprehensive spraying of the mold, replacing the complex spraying method of the prior art of clamping the mold by controlling the fixture or accurately placing the mold into the placement groove, reducing the difficulty of the spraying work of the staff and improving the spraying efficiency of the mold.

[0023] Example 2: Reference Figure 1-10 , a mold spraying device for refractory materials. On the basis of Example 1, further, the spraying part includes a support 6 fixedly mounted on a workbench 1, a connecting seat 7 fixedly mounted on the support 6, a driving motor 701 is arranged on the connecting seat 7, a reciprocating screw 702 connected to the output shaft of the driving motor 701 is rotatably connected in the connecting seat 7, a sleeve 703 slidably connected to the connecting seat 7 is threadedly connected to the reciprocating screw 702, a connecting plate 704 is fixedly mounted on the sleeve 703, and a spraying assembly is connected to the connecting plate 704.

[0024] Furthermore, the spraying assembly includes a material box 8 fixed on the workbench 1, a pump body 801 is fixed on the material box 8, a material guide pipe 802 is connected to the pump body 801, the end of the material guide pipe 802 away from the material box 8 passes through the support 6 and is connected to a nozzle 803, and the nozzle 803 is connected to the connecting plate 704.

[0025] Specifically, the driving motor 701 and the pump body 801 of the spraying part are controlled to operate. When the pump body 801 is in operation, the spray material in the material box 8 is extracted, and the spray material is transported into the nozzle 803 through the material guide pipe 802. When the driving motor 701 is in operation, it drives the reciprocating screw 702 to rotate. The sleeve 703 threadedly connected to the reciprocating screw 702 drives the nozzle 803 to move axially along the reciprocating screw 702 through the connecting plate 704, so that the nozzle 803 sprays the inclined mold body 3 from top to bottom.

[0026] Example 3: Reference Fig. 9 and Fig.10 , a mold spraying device for refractory materials, based on Example 2, further, a pin shaft 7041 is arranged between the nozzle 803 and the connecting plate 704, and a torsion spring for resetting and rotating the nozzle 803 is sleeved on the pin shaft 7041, and a plurality of protrusions 705 are arranged on the outer side of the connecting seat 7 along its length direction, and the nozzle 803 and the protrusions 705 are movably abutted against each other.

[0027] Specifically, when the sleeve 703 drives the nozzle 803 to move along the connecting seat 7 through the connecting plate 704, the nozzle 803 intermittently abuts against the protrusion 705 on the side of the connecting seat 7. When the nozzle 803 abuts against the protrusion 705, the nozzle 803 is subjected to force and swings around the pin shaft 7041. When the nozzle 803 does not abut against the protrusion 705, the nozzle 803 is no longer subjected to force and will reset and rotate under the action of the torsion spring, so that the nozzle 803 swings left and right when spraying the mold body 3, and then the nozzle 803 sprays the two sides of the mold body 3, thereby improving the comprehensiveness of the spraying on the surface of the mold body 3.

[0028] Example 4: Reference Figure 1 , Figure 4 and Figure 7 , a mold spraying device for refractory materials, based on Example 3, further, the connecting seat 7 and the support 6 are arranged obliquely, and the connecting seat 7 is arranged parallel to the mold body 3 placed on the movable base 2.

[0029] Specifically, by slanting the connecting seat 7 and the support 6, and slanting the connecting seat 7 and the mold body 3 placed on the movable base 2, when the nozzle 803 moves up and down along the connecting seat 7 to spray the mold body 3, the nozzle 803 always maintains the same distance from the mold body 3 when moving up and down, so that the spraying distance of the nozzle 803 at each position of the inclined mold is the same, and then the spraying angle and spraying force of the nozzle 803 when moving up and down for spraying are basically consistent, thereby ensuring the spraying uniformity and spraying effect of the nozzle 803 on the mold.

[0030] Example 5: Reference Figure 1-9 , a mold spraying device for refractory materials, based on Example 4, further, the pushing and flipping assembly includes a side plate 9 fixedly connected to the connecting seat 7, an electric telescopic rod 901 is fixedly provided on the side plate 9, and a push rod 902 that is movably opposed to the mold body 3 is fixedly provided at one end of the electric telescopic rod 901 away from the side plate 9.

[0031] Furthermore, support plates 10 are fixedly provided on both sides of the movable base 2 , and each of the support plates 10 is connected to an elastic telescopic rod 1001 , and the end of the elastic telescopic rod 1001 is connected to an abutment plate 1002 that movably abuts against the mold body 3 .

[0032] Specifically, as the mobile base 2 moves, the mold body 3 being sprayed moves away from the spraying part that has completed the spraying work on it. After the mold body 3 that has completed the spraying on one side moves to between the two spraying parts, the electric telescopic rod 901 is controlled to work. The electric telescopic rod 901 stretches and pushes the inclined mold body 3 through the push rod 902, so that the mold body 3 is turned over under the limit of the limit bar 402 at its bottom. The mold body 3 is gradually turned over from the inclined state to the vertical state and abuts against the abutment plate 1002 at the end of the elastic telescopic rod 1001. As the push rod 902 is pushed, the mold body 3 is turned over to the vertical state. With the continued pushing of rod 902, the mold body 3 changes from a vertical state to an inclined state again. The mold body 3 pushed by the push rod 902 to be inclined exerts a force on the abutment plate 1002, and the elastic telescopic rod 1001 gradually contracts, so that the mold body 3 pushed by the push rod 902 to be inclined is slowly lowered to the side support plate 502 on the other side, avoiding the mold body 3 pushed by the push rod 902 to flip directly onto the side support plate 502, causing a large collision between the mold body 3 and the side support plate 502, causing damage to the coating sprayed on the surface of the mold body 3.

[0033] Example 6: Reference Figure 1 , Figure 2 , Fig. 9 and Fig.11 , a mold spraying device for refractory materials, based on Example 5, further, a slider 201 is fixedly provided at the bottom of the movable base 2, a slide groove 101 for the sliding of the slider 201 is opened on the workbench 1, a rack plate 202 is arranged on the slider 201, a gear box 11 is fixedly provided on the workbench 1, the input shaft of the gear box 11 is connected to the reciprocating screw 702, and the output shaft of the gear box 11 is connected to the driving gear 111 meshing with the rack plate 202.

[0034] Specifically, when the reciprocating screw 702 rotates, the input shaft of the gear box 11 will be driven to rotate at the same time. Through the gear transmission inside the gear box 11, the gear box 11 converts the high-speed rotation of its input shaft into the low-speed rotation of its output shaft. The driving gear 111 of the output shaft of the gear box 11 meshes with the rack plate 202 for transmission, so that the movable base 2 drives the mold body 3 placed on the upper side to move slowly, so that the nozzle 803 sprays the mold body 3 placed on the movable base 2 in turn. The nozzle 803 moves up and down to spray and the mold moves horizontally at the same time, so that the above-mentioned components act as a linkage mechanism with continuous action, so that the various components cooperate and are related to each other to achieve coordinated movement, so that the mold spraying action is more coherent and smooth, and the mold spraying effect and spraying efficiency are guaranteed.

[0035] The present invention also discloses a method for spraying a mold for a refractory material, which uses a refractory mold spraying device for spraying, and comprises the following steps: S1: Place multiple mold bodies 3 to be sprayed on the support platform 4, and make one side of the mold body 3 abut against the side support plate 502 of the support seat 5, and the mold body 3 is placed on the movable base 2 at an angle, and the limit strip 402 on the base 401 limits the lower side of the mold body 3, and the side of the mold body 3 tilted upward is not blocked by other components; S2: Then, the driving motor 701 of the spraying part is controlled to operate. When the driving motor 701 operates, the reciprocating screw 702 is driven to rotate. The sleeve 703 threadedly connected to the reciprocating screw 702 drives the spray head 803 to move axially along the reciprocating screw 702 through the connecting plate 704, so that the spray head 803 sprays the inclined mold body 3 from top to bottom. When the sleeve 703 drives the nozzle 803 to move along the connection seat 7 through the connection plate 704, the nozzle 803 intermittently abuts against the convex block 705 on the side of the connection seat 7. When the nozzle 803 abuts against the convex block 705, the nozzle 803 is subjected to force and swings around the pin shaft 7041. When the nozzle 803 does not abut against the convex block 705, the nozzle 803 is no longer subjected to force and will reset and rotate under the action of the torsion spring, so that the nozzle 803 swings left and right when spraying the mold body 3, and then the nozzle 803 sprays the two sides of the mold body 3. When the reciprocating screw 702 rotates, it will also drive the input shaft of the gear box 11 to rotate. Through the gear transmission inside the gear box 11, the gear box 11 converts the high-speed rotation of its input shaft into the low-speed rotation of its output shaft. The driving gear 111 of the output shaft of the gear box 11 meshes with the rack plate 202 for transmission, thereby causing the movable base 2 to drive the mold body 3 placed on the upper side to move slowly, so that the nozzle 803 sprays the mold body 3 placed on the movable base 2 in sequence. S3: With the movement of the mobile base 2, the mold body 3 to be sprayed moves away from the spraying part that has completed the spraying work on it. After the mold body 3 that has completed the spraying on one side moves to between the two spraying parts, the electric telescopic rod 901 is controlled to work. The electric telescopic rod 901 stretches and pushes the inclined mold body 3 through the push rod 902, so that the mold body 3 is turned over under the limit of the limit bar 402 at its bottom. The mold body 3 is gradually turned over from the inclined state to the vertical state and abuts against the abutment plate 1002 at the end of the elastic telescopic rod 1001. With the continued pushing of the push rod 902, the mold body 3 is transformed from the vertical state to the inclined state again. The mold body 3 pushed by the push rod 902 to tilt exerts a force on the abutment plate 1002, and the elastic telescopic rod 1001 gradually contracts, so that the mold body 3 pushed by the push rod 902 to tilt is slowly lowered to the side support plate 502 on the other side. S4: With the continuous movement of the movable base 2, the mold body 3 that has completed the flipping work moves to another spraying part, and the other spraying part repeats the operation steps of S2 to spray the upper side of the flipped mold body 3, thereby achieving comprehensive spraying of the mold body 3.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

A method for spraying a mold for a refractory material, using the device for spraying a mold for a refractory material according to claim 7 for spraying, characterized in that: The following steps are involved: S1: placing a plurality of mold bodies (3) to be sprayed on a support platform (4), with one side of the mold body (3) abutting against a side support plate (502) of a support seat (5), the mold body (3) being placed obliquely on a movable base (2), a limiting strip (402) on the base (401) limiting the lower side of the mold body (3), and the side of the mold body (3) tilted upward is not blocked by other components; S2: Then, the driving motor (701) of the spraying part is controlled to operate. When the driving motor (701) operates, it drives the reciprocating screw (702) to rotate. The sleeve (703) threadedly connected to the reciprocating screw (702) drives the spray head (803) to move along the axial direction of the reciprocating screw (702) through the connecting plate (704), so that the spray head (803) sprays the inclined mold body (3) from top to bottom; When the sleeve (703) drives the spray head (803) to move along the connection seat (7) through the connection plate (704), the spray head (803) intermittently abuts against the protrusion (705) on the side of the connection seat (7). When the spray head (803) abuts against the protrusion (705), the spray head (803) is subjected to force and swings around the pin shaft (7041). When the spray head (803) is not abutted against the protrusion (705), the spray head (803) is no longer subjected to force and will reset and rotate under the action of the torsion spring, so that the spray head (803) swings left and right when spraying the mold body (3), thereby causing the spray head (803) to spray the two side surfaces of the mold body (3); When the reciprocating screw (702) rotates, it also causes the input shaft of the gear box (11) to rotate. Through the gear transmission inside the gear box (11), the gear box (11) converts the high-speed rotation of its input shaft into the low-speed rotation of its output shaft. The driving gear (111) of the output shaft of the gear box (11) meshes with the rack plate (202) for transmission, thereby causing the movable base (2) to drive the mold body (3) placed on the upper side to move slowly, so that the spray head (803) sprays the mold body (3) placed on the movable base (2) in sequence; S3: As the movable base (2) moves, the mold body (3) being sprayed moves away from the spraying part that has completed the spraying work on it. After the mold body (3) that has completed the spraying on one side moves to between the two spraying parts, the electric telescopic rod (901) is controlled to work. The electric telescopic rod (901) stretches and pushes the inclined mold body (3) through the push rod (902), so that the mold body (3) is turned over under the limit of the limit bar (402) at its bottom, and the mold body (3) gradually moves from the inclined state. The mold body (3) is flipped to a vertical state and abuts against the abutment plate (1002) at the end of the elastic telescopic rod (1001). As the push rod (902) continues to push, the mold body (3) is transformed from a vertical state to an inclined state again. The mold body (3) pushed and tilted by the push rod (902) exerts a force on the abutment plate (1002). The elastic telescopic rod (1001) gradually contracts, so that the mold body (3) pushed and tilted by the push rod (902) is slowly lowered to the side support plate (502) on the other side. S4: As the movable base (2) continues to move, the mold body (3) that has completed the flipping work moves to another spraying section, and the other spraying section repeats the operation steps of S2 to spray the upper side of the flipped mold body (3), thereby achieving full spraying of the mold body (3).
