Description

Technical Field

[0001] The invention relates to the technical field of refractory casting block moulds, in particular to a mould structure for producing refractory casting blocks. Background Art

[0002] Refractory castables refer to a mixture of refractory aggregates, binders and admixtures, which are mixed with water (or liquid binders) to form mud that can be constructed by pouring. The difference from other amorphous refractory materials is that refractory castables have a certain coagulation and hardening time after construction. Therefore, after casting and molding, they need to be cured for a certain period of time before demoulding, and then they can be put into baking and use after a suitable period of natural curing. Refractory castables are a mixture of refractory aggregates, powders and binders. After adding water or other liquids, they are suitable for construction by pouring and vibration methods. They can also be prefabricated into prefabricated parts with specified shapes and sizes for the construction of industrial furnace linings. In order to improve the physical and chemical properties and construction performance of refractory castables, appropriate amounts of admixtures are often added, such as plasticizers, dispersants, accelerators, retarders, expanders, debonding-gelling agents, etc. In addition, for refractory castables used in areas with large mechanical forces or strong thermal shock, if an appropriate amount of stainless steel fiber is added, the toughness of the material will be significantly increased. If inorganic fibers are added to insulating refractory castables, it can not only enhance toughness, but also help improve its thermal insulation performance. Since the basic material composition of refractory castables (such as aggregates and powders, admixtures, binders and additives), coagulation and hardening process, construction methods, etc. are similar to concrete in civil engineering, it was once called refractory concrete.

[0003] Refractory casting blocks, as the name implies, are cast through molds. In the existing casting molds of refractory casting blocks, there are more or less problems and defects when they are used, such as:

[0004] The refractory casting block contains sticky materials, which are easy to stick to the mold structure, which will make it difficult to demould the casting block, and it is also easy to cause pulling damage to the casting block product;

[0005] If the casting block material stuck in the mold remains, it is easy to affect the subsequent casting block products. That is, defective products are likely to appear in the next casting at the location with sticky materials.

[0006] Therefore, we propose a mold for producing refractory casting blocks to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a mold structure for producing refractory casting blocks to solve the problems raised in the above background technology.

[0008] Refractory casting blocks, as the name implies, are cast through molds. In the existing casting molds of refractory casting blocks, there are more or less problems and defects when they are used, such as:

[0009] The refractory casting block contains sticky materials, which are easy to stick to the mold structure, which will make it difficult to demould the casting block, and it is also easy to cause pulling damage to the casting block product;

[0010] If the casting block material stuck in the mold remains, it is easy to affect the subsequent casting block products. That is, defective products are likely to appear in the next casting at the location with sticky materials.

The two base plates are designed with protruding structures and grooves, on the one hand, to increase the position accuracy in the process of forming the casting space, and on the other hand, to achieve sealing of the bottom to avoid leakage of casting material.

The movable frame is clamped on the outer edge of the side baffle, and the movable frame together with the end baffle thereon can move along the side baffle.

No matter the bottom or the side, there is no excessive force between the entire mold and the casting block, which can not only quickly realize demoulding, but also improve the demoulding completion of the casting block and reduce the probability of defective products.

[0024] 2. The mold structure for the production of refractory casting blocks adopts a synchronous and modular design of the side baffles and the end baffles, which greatly reduces the difficulty of using the mold.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-5 The present invention provides a technical solution for the mold structure for producing refractory casting blocks:

[0035] Embodiment 1:

[0036] The mold includes a mold base 1, with strip-shaped sockets 2 opened on both sides of the top of the mold base 1, side baffles 3 inserted in the inner cavity of the sockets 2, a movable frame 4 installed between the side baffles 3 on both sides, and an end baffle 5 set in the middle of the movable frame 4.

[0037] Limit rods 9 are fixedly installed at both sides of the bottom of the side baffle 3 , and springs 10 are sleeved on the outer rings of the limit rods 9 .

[0038] A through hole 11 is provided on the mold base 1 , a driving shaft 12 is installed in the inner cavity of the through hole 11 , and a threaded structure is provided on the outer ring of the driving shaft 12 , and a limit block 13 is threadedly connected to the outer ring of the threaded part of the driving shaft 12 .

[0039] Among them, a limiting plate is threadedly installed at the bottom of the limiting rod 9, the top of the spring 10 is against the bottom of the mold base 1, the bottom of the spring 10 is against the top of the limiting plate, and the spring 10 is in a compressed state.

[0040] The top of the limit block 13 is fixedly connected to the bottom of the end baffle 5 , the thread structures on both sides of the drive shaft 12 are in opposite directions, and a rotating wheel structure 16 is installed at both ends of the drive shaft 12 .

[0041] Among them, a bottom plate 6 is fixedly installed at the bottom of the side opposite to the end baffle 5, a protruding structure 7 is arranged on the right side of the bottom plate 6 at the left position, and a groove 8 matched with the protruding structure 7 is arranged on the left side of the bottom plate 6 at the right position. The design of the two bottom plates 6 is mainly to enable the bottom of the casting block to be pulled away from the bottom of the mold during demoulding, and to achieve demoulding of the bottom by sliding friction, which effectively avoids the problem of the casting block easily falling off and causing notches at the sticking position at the bottom when demoulding. The two bottom plates 6 are designed with protruding structures 7 and grooves 8, on the one hand, to increase the position accuracy in the process of forming the casting space, and on the other hand, to achieve sealing of the bottom to prevent the casting material from leaking out.

[0042] The side baffle 3 is in the shape of a figure 7 as a whole, and the middle part of the moving frame 4 is in a convex shape, and the two sides of the moving frame 4 are clamped on the outer edge of the side baffle 3. The moving frame 4 together with the end baffle 5 thereon can move along the side baffle 3. On the one hand, the side baffles 3 at the two sides can be limited by the moving frame 4 to avoid deformation and damage caused by the extrusion of the casting material during the casting process. On the other hand, the size of the casting space can be adjusted to cast different casting block products.

[0043] Among them, an inclined block structure 14 is arranged on one side of the opposite side of the moving frame 4, a chamfered structure 15 is arranged at both ends of the bottom edge of the side baffle 3, and a retaining strip structure 18 is fixedly installed at both ends of the top of the mold base 1. The main purpose of the chamfered structure 15 is that when the moving frame 4 moves, especially when it is reassembled into a casting space, the inclined block structure 14 can be better inserted into the bottom position of the edge of the side baffle 3, and then when the moving frame 4 is subsequently moved, the entire side baffle 3 can be gradually propped up, and together with the end baffle 5, a semi-enclosed casting space is formed again.

[0044] In this embodiment, when the device is used to produce refractory casting blocks, the entire device is as follows Figure 1 In the state shown, the side baffles 3 and the end baffles 5 together form a semi-enclosed pouring space, and the mixed material can be poured directly in the pouring space.

[0045] After pouring is completed and formed, demolding operation is required. In the present technical solution, one of the rotating wheel structures 16 is directly rotated, and the rotating wheel structure 16 drives the driving shaft 12 thereon to rotate. When the driving shaft 12 rotates, it drives the limit blocks 13 on both sides to continuously move to both sides, and then drives the two end baffles 5 to move to both sides. When the end baffles 5 move, they drive the two bottom film plates 6 to separate from each other and also move to both sides.

[0046] When the bottom plate 6 moves, it can gradually separate from the bottom of the casting block during the slow movement, and the two are in sliding friction. At the moment when the moving frame 4 separates from the side baffle 3, the elastic force of the spring 10 will apply a downward force to the side baffle 3. In the case of no sticking, the side baffle 3 will overcome the friction and move downward slowly, gradually separating from the casting block. When there is sticking, the operator can assist in pressing the side baffle 3 downward to demold the casting block.

[0047] After demoulding is completed, the wheel structure 16 is directly rotated in the opposite direction to reset the end baffle 5. During the movement of the end baffle 5, the tilting block structure 14 cooperates with the chamfering structure 15 on the side baffle 3 to synchronously shovel up the side baffle 3 at both ends and gradually pull it upward until a semi-enclosed casting cavity is re-enclosed.

[0048] In the present technical solution, the side baffle 3 and the end baffle 5 can be completely separated, and the design of synchronous action can make the demoulding of the casting block faster and better. No matter the bottom or the side, there is no excessive force between the entire mold and the casting block. Not only can demoulding be achieved quickly, but also the demoulding completion of the casting block can be improved, and the probability of defective products can be reduced.

[0049] The synchronous linkage and modular design of the side baffle 3 and the end baffle 5 greatly reduces the difficulty of using the mold, and also provides the possibility and convenience for replacing various components of the mold, which can effectively reduce production costs.

[0050] Embodiment 2:

[0051] The mold includes a mold base 1, with strip-shaped sockets 2 opened on both sides of the top of the mold base 1, and side baffles 3 inserted in the inner cavity of the socket 2. The bottom of the side baffles 3 passes through the socket 2 and extends into the cavity of the mold base 1. The thickness and length of the side baffles 3 are equal to the width and length of the inner side of the socket 2.

[0052] Among them, Figure 4 As shown, scraper structures 17 are fixedly installed on both sides of the inner wall of the mold base 1.

[0053] The scraper structure 17 is designed to be inclined with an inclination angle of 15-30°. The upturned end of the scraper structure 17 is in an inclined blade shape and contacts the side surface of the side baffle 3 .

[0054] In this embodiment, based on the embodiment 1, especially when demolding, when the side baffle 3 gradually moves downward along the socket 2, the side baffle 3 first scrapes through the upper edge of the socket 2 to scrape off a part of the sticky matter. Then, when the part in contact with the castable material moves to the scraper structure 17, it starts to contact the blade end of the scraper structure 17 again, and the side of the side baffle 3 is deeply scraped and cleaned by the blade-shaped scraper structure 17, thereby effectively solving the problem of easy residue of sticky matter in the castable material. In the actual production process, a recovery box can also be placed in the cavity area of ​​the mold base 1, and the material can be collected through the inclined surface of the scraper structure 17 for material reuse.

[0055] In the present technical solution, by designing and using the socket 2, the liftable side baffle 3 and the inclined scraper structure 17 with a blade-like end, the inner wall of the mold, that is, the side in contact with the casting material, can be cleaned when the casting block is demolded to avoid excessive sticky matter, thereby effectively solving the problem of residual sticky matter on the inner wall of the mold and the easy occurrence of defective products.

[0056] When cleaning the sticky materials, the scraped sticky materials can also be recycled and reused. For mass production manufacturers, the amount of recycled waste is very large, which can reduce production costs to a certain extent.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
