Description

Technical Field

[0001] The invention relates to the field of block moulds, in particular to a self-insulating foamed concrete block mould frame. Background Art

[0002] Self-insulating foamed concrete bricks utilize the non-combustibility of cement and the large number of closed pores in concrete to achieve fire resistance, lightweight, and thermal insulation. They are currently the most ideal material for wall insulation and wall insulation fire barriers. The main production process involves loading, mixing, stirring, injection molding, foaming, initial curing, demolding, cutting, and packaging the materials containing polystyrene foam particles (EPS).

[0003] Existing molds for self-insulating foamed concrete bricks typically consist of a mold frame and a base plate. The mold frame is pressed onto the base plate to form the complete mold, and the molding process is completed by placing the material into the mold. The mold frame is a frame structure welded together from multiple steel plates. During use, the mold frame and base plate are locked together with bolts to form the mold. After the material is poured and formed, the bolts are removed, and the mold frame is lifted with a hoist to separate the mold frame from the base plate, allowing the self-insulating foamed concrete brick to be demolded. However, the mold frame structure, which is welded together from multiple steel plates, can easily cause the finished product to adhere to the inner surface of the mold frame during molding, making it difficult to demold. Summary of the Invention

[0004] Therefore, in view of the above problems, the present invention provides a self-insulating foamed concrete block mold frame, which mainly solves the problem of difficulty in demoulding in the prior art.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A self-insulating foamed concrete block mold frame includes an outer frame, which is defined as a longitudinal direction extending along the length direction of the outer frame and a transverse direction extending along the width direction of the outer frame. The outer frame is provided with at least one molding unit for molding a single product, and the molding unit includes two first frame plates, two second frame plates and a connecting component. The two first frame plates are distributed along the transverse direction, and the two second frame plates are distributed along the longitudinal direction. One or two of the first frame plates are movably connected to the outer frame through the connecting component, and the first frame plates are spaced apart from the outer frame. When the mold frame is connected to the bottom plate, the two first frame plates and the two second frame plates form a mold cavity. When the mold frame is separated from the bottom plate, the first frame plate connected to the connecting component swings laterally outward and downward to separate it from the two second frame plates. The lower edges of the first frame plate and the second frame plate are both provided with sealing gaskets.

[0007] Furthermore, the two second frame plates are distributed between the two first frame plates.

[0008] Furthermore, one or two of the second frame plates are movably connected to the outer frame through a connecting component, and the second frame plates are spaced apart from the outer frame. When the mold frame is connected to the base plate, the two first frame plates and the two second frame plates form a mold cavity. When the mold frame is separated from the base plate, the second frame plate connected to the connecting component swings longitudinally outward and downward to separate it from the two first frame plates.

[0009] Furthermore, the number of the connecting components located on the first frame plate or the second frame plate is three or four, and they are distributed in upper and lower rows.

[0010] Furthermore, the connecting assembly includes a first connecting seat, a second connecting seat and a connecting plate. The first connecting seat is fixed on the outer frame, the second connecting seat is fixed on the first frame plate or the second frame plate, and the two ends of the connecting plate are respectively hinged to the first connecting seat and the second connecting seat.

[0011] Furthermore, the first connecting seat and the second connecting seat both include a first hinge plate and a second hinge plate. The first hinge plate and the second hinge plate are distributed in parallel and spaced apart so that a mounting groove for the connecting plate to be embedded is formed between the first hinge plate and the second hinge plate. The first hinge plate and the second hinge plate are both provided with a first through hole, and second through holes are provided at both ends of the connecting plate. The connecting plate is connected to the first connecting seat or the second connecting seat by bolts passing through the first through hole and the second through hole.

[0012] Furthermore, two connecting plates located on two adjacent molding units and close to each other are arranged on the same first connecting seat.

[0013] By adopting the above technical solution, the beneficial effects of the present invention are as follows: the self-insulating foamed concrete block mold frame is provided with a first frame plate and a second frame plate respectively connected to the outer frame through a connecting assembly. When the outer frame is connected to the bottom plate, the first frame plate and the second frame plate are lifted up and reset by the bottom plate. At this time, the two first frame plates and the two second frame plates surround a mold cavity, and the material is poured into the mold cavity for molding. When demoulding, by lifting the outer frame, the first frame plate can swing outward and downward horizontally, and the second frame plate can swing outward and downward longitudinally. Under the action of the gravity of the foamed concrete block, it can be separated from the first frame plate and the second frame plate, and then the first frame plate swings outward and downward horizontally under the action of the self-generated gravity, and the second frame plate can be separated from the first frame plate and the second frame plate. Under the action of the body gravity, it swings longitudinally outward and downward, so that the first frame plate and the second frame plate are separated, which is convenient for separating the foamed concrete blocks and realizing automatic demoulding. In the existing welded fixed mold frame, the foamed concrete blocks adhere to the surface of the mold frame after forming. Since the integrated structure of the mold frame forms an embracing shape to hold the foamed concrete blocks, it makes it difficult to demould the foamed concrete blocks. In comparison, the design of the present application document is to separate the first frame plate and the second frame plate and swing them outward, so that the foamed concrete blocks are separated from the first frame plate and the second frame plate, and the self-weight of the first frame plate and the second frame plate also provides pulling force, thereby ensuring the demoulding of the foamed concrete blocks and improving the success rate of demoulding.

[0024] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0025] The embodiments of the present invention are:

[0026] Example 1:

[0027] refer to Figure 1 、 Figure 3 As shown, a self-insulating foamed concrete block mold frame includes an outer frame 1, which is defined as a longitudinal direction extending along the length direction of the outer frame 1 and a transverse direction extending along the width direction of the outer frame. The outer frame 1 is provided with two molding units 10 for molding a single product, and the molding unit 10 includes two first frame plates 2, two second frame plates 3 and a connecting component 4. The two first frame plates 2 are distributed in the transverse direction, and the two second frame plates 3 are distributed in the longitudinal direction. The two first frame plates 2 are movably connected to the outer frame 1 through the connecting component 4, and the first frame plates 2 and the outer frame 1 are distributed at intervals. The two second frame plates 3 are movably connected to the outer frame 1 through the connecting component 4, and the second frame plates 3 are distributed at intervals. When the mold frame is connected to the bottom plate, the two first frame plates 2 and the two second frame plates 3 enclose a mold cavity 5. When the mold frame is separated from the bottom plate, the first frame plate 2 connected to the connecting component 4 swings outward and downward laterally to separate it from the two second frame plates 3, and the second frame plate 3 connected to the connecting component 4 swings outward and downward longitudinally to separate it from the two first frame plates 2.

[0028] The self-insulating foamed concrete block mold frame is provided with a first frame plate 2 and a second frame plate 3 which are connected to the outer frame 1 respectively through a connecting assembly 4. When the outer frame 1 is connected to the bottom plate, the first frame plate 2 and the second frame plate 3 are lifted up and reset by the bottom plate. At this time, the two first frame plates 2 and the two second frame plates 3 form a mold cavity 5, and the material is poured into the mold cavity for molding. When demoulding, the outer frame 1 is lifted. Since the first frame plate 2 can swing outward and downward laterally and the second frame plate 3 can swing outward and downward longitudinally, they can be separated from the first frame plate 2 and the second frame plate 3 under the action of the gravity of the foamed concrete block. Then, the first frame plate 2 swings outward and downward laterally under the action of its own gravity, and the second frame plate 3 swings outward and downward longitudinally under the action of its own gravity. The first frame plate 2 and the second frame plate 3 are swung outward and downward longitudinally to separate the first frame plate 2 and the second frame plate 3, which facilitates the separation of the foamed concrete blocks and realizes automatic demoulding. In the existing welded fixed mold frame, the foamed concrete blocks adhere to the surface of the mold frame after forming. Since the integrated structure of the mold frame forms an embracing shape to hold the foamed concrete blocks, it is difficult to demould the foamed concrete blocks. In comparison, the design of the present application document is to separate the first frame plate 2 and the second frame plate 3 and swing them outward, so that the foamed concrete blocks are separated from the first frame plate 2 and the second frame plate 3, and the self-weight of the first frame plate 2 and the second frame plate 3 also provides pulling force, thereby ensuring the demoulding of the foamed concrete blocks and improving the success rate of demoulding.

[0029] In addition, the above-mentioned first frame plate 2, second frame plate 3 and outer frame 1 are all provided with connecting components 4. Of course, the connecting components 4 can also be set between only a single or two first frame plates 2 or second frame plates 3 and the outer frame 1, and the remaining first frame plates 2 and second frame plates 3 are fixed on the outer frame 1. Therefore, when demoulding, only a single or two first frame plates 2 or second frame plates 3 are swung outward and downward, which can also separate the adsorption force of the foamed concrete blocks from the first frame plates 2 and second frame plates 3, making it easier to demould. However, the demoulding effect of this method is obviously not as good as the demoulding effect of the above-mentioned structure.

[0030] In this embodiment, reference Figure 2 、 Figure 4 and Figure 5 As shown, the number of connecting components 4 located on the first frame plate 2 or the second frame plate 3 is three or four, and they are distributed in upper and lower rows. Preferably, the number of connecting components 4 located on the first frame plate 2 or the second frame plate 3 is four, that is, two are distributed on the upper part of the first frame plate 2 or the second frame plate 3, and two are distributed on the lower part of the first frame plate 2 or the second frame plate 3, so that the swing stability of the first frame plate 2 and the second frame plate 3 is good, deviation is avoided, the mold can be better closed, and the molding accuracy of the product is improved.

[0031] Specifically, the connecting assembly 4 includes a first connecting seat 41, a second connecting seat 42 and a connecting plate 43, the first connecting seat 41 is fixed to the outer frame 1, and the second connecting seat 42 is fixed to the first frame plate 2 or the second frame plate 3, and the two ends of the connecting plate 43 are hinged to the first connecting seat 41 and the second connecting seat 42 respectively, so that the connecting plate 43 can swing, thereby driving the first frame plate 2 and the second frame plate 3 connected to the other end of the connecting plate 43 to swing downward, and due to the hinged manner of the second connecting seat 42 and the other end of the connecting plate 43, and the number of the connecting assemblies 4 located on the first frame plate 2 or the second frame plate 3 is four, and they are distributed in upper and lower rows, thereby limiting the folding of the first frame plate 2 and the second frame plate 3, so that the folding of the first frame plate 2 and the second frame plate 3 is outward and downward, and it is always in a state perpendicular to the horizontal plane, which can prevent the upper ends of the first frame plate 2 and the second frame plate 3 from abutting against the foamed concrete blocks during the demoulding process, thereby avoiding damage to the foamed concrete blocks and improving the success rate of demoulding;

[0032] In addition, the first connecting seat 41 and the second connecting seat 42 both include a first hinge plate 101 and a second hinge plate 102. The first hinge plate 101 and the second hinge plate 102 are distributed in parallel and are spaced apart so that a mounting groove 103 for the connecting plate 43 to be embedded is formed between the first hinge plate 101 and the second hinge plate 102. The first hinge plate 101 and the second hinge plate 102 are both provided with a first through hole 104. Second through holes 105 are provided at both ends of the connecting plate 43. The connecting plate 43 is connected to the first connecting seat 41 or the second connecting seat 42 by bolts 106 passing through the first through holes 104 and the second through holes 105. The movement direction of the connecting plate 43 is limited by the first hinge plate 101, the second hinge plate 102 and the bolts 106, thereby avoiding the problem of the connecting plate 43 swinging horizontally while swinging vertically, thereby improving stability, and having high connection strength, simple structure and good use effect.

[0033] It is worth noting that when the mold frame 1 is connected to the base plate, the two first frame plates 2 and the two second frame plates 3 form a mold cavity 5. At this time, the connecting plate 43 is distributed laterally, that is, the midpoint line of the two second through holes 105 on the connecting plate 43 is distributed laterally, so that the first connecting seat 41, the second connecting seat 42 and the connecting plate 43 are in a self-locking state, which is used to support the first frame plate 2 and the second frame plate 3, play a supporting role in casting and molding, avoid leakage of materials, and improve the strength and sealing performance of the mold frame. In addition, the lower part of the outer frame 1 is provided with a top block 9 for limiting the first frame plate 2 or the second frame plate 3.

[0034] Of course, the above only provides the structure of the connecting component 4 and the structure of the first connecting seat 41 and the second connecting seat 42 of a specific embodiment, but does not exclude other ways to achieve the structure of the connecting component in which, when the mold frame is connected to the base plate, the two first frame plates 2 and the two second frame plates 3 enclose the mold cavity 5, and when the mold frame is separated from the base plate, the first frame plate 2 connected to the connecting component 4 swings laterally outward and downward to separate it from the two second frame plates 3, and the second frame plate 3 connected to the connecting component 4 swings longitudinally outward and downward to separate it from the two first frame plates 2.

[0035] Example 2:

[0036] In this embodiment, reference Figure 6 、 Figure 7 and Figure 8 As shown, the outer frame 1 is provided with twelve molding units 10 for molding a single product, and each molding unit 10 is distributed in a matrix. In order to reduce the space occupied by the connecting assembly 4 and the outer frame 1 and improve the compactness of the mold frame, two connecting plates 43 located on two adjacent molding units 10 and close to each other are provided on the same first connecting seat 41, that is, two connecting plates 43 are embedded in the mounting groove 103 between the first hinge plate 101 and the second hinge plate 102 on the first connecting seat 41, and the bolts 106 pass through the second through holes 105 on the two connecting plates 43 and the first through holes 104 on the first hinge plate 101 and the second hinge plate 102 to lock and connect them, so that the two connecting plates 43 can respectively realize hinged swing. At the same time, the first connecting seat 41 of the structure is provided at the lower end of the crossbeam of the outer frame 1 to avoid the connection plate from being restricted when swinging downward.

[0037] At the same time, reference Figure 8 and Figure 10 As shown, in order to improve the sealing performance of the connection between the first frame plate 2 and the second frame plate 3, the two second frame plates 3 are distributed between the two first frame plates 2. When the mold is closed to form the mold cavity 5, the two second frame plates 3 are clamped by the two first frame plates 2, so that the two lateral end faces of the second frame plates 3 are against the surface of the first frame plates 2, thereby improving the sealing effect. Furthermore, sealing components 6 are provided on the two lateral end faces of the second frame plates 3, which can squeeze the sealing components 6 when the two first frame plates 2 move downward, while ensuring that the sealing components 6 are active, so that the second frame plates 3 can move toward each other, avoiding the problem of jamming and retention, and ensuring the mold closing.

[0038] Specifically, the sealing assembly 6 includes a base 61 clamped on the two lateral end surfaces of the second template 3, an extension portion 62 bent and extended from the inner end of the base 61 laterally outward and longitudinally outward, and a guide portion 63 provided at the free end of the extension portion 62. The base 61, the extension portion 62 and the guide portion 63 are an integrated structure. Through the extension portion 62, a clamping groove 64 is formed between the guide portion 63 and the base 61. An elastic member 65 made of rubber is clamped in the clamping groove 64. The elastic member 65 has a U-shaped structure and a clamping portion 66 extends outward from the outer end. The base 61 and the extension portion 62 are both provided with a clamping groove 67 for clamping the clamping portion 66. The guide portion 63 abuts against the elastic member 65. The hardness of the elastic member 65 is The index is greater than the hardness index of the sealing component 6. When the mold frame is connected to the bottom plate, the guide portion 63 on the sealing component 6 preferably abuts against the surface of the first frame plate 2, and the two first frame plates 2 clamp the guide portion 63 downward, and the second frame plate 3 moves toward each other. Through the guiding effect of the guide portion 63 and the sliding with the first frame plate 2, the sealing component 6 clamps the elastic member 65 to bend and move, and the extension portion 62 abuts against the surface of the first frame plate 2 to achieve sealing. The sealing structure is good, and the inner ends of the two transverse end surfaces of the second frame plate 3 are provided with limit blocks 7, and the extension portion 62 abuts against the limit blocks 7. The width of the limit blocks 7 is smaller than the width of the sealing component 6, which plays a limiting role and improves the firmness of the installation of the sealing component 6.

[0039] Of course, the sealing assembly 6 can also be a sealing strip embedded on both lateral end surfaces of the second frame plate 3 .

[0040] In this embodiment, sealing gaskets 8 are provided at the lower edges of the first frame plate 2 and the second frame plate 3 to improve the sealing performance of the connection between the first frame plate 2, the second frame plate 3 and the bottom plate.

[0041] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
