Description

Technical Field

[0001] The invention relates to the technical field of concrete blocks, in particular to a manufacturing device for a self-insulating concrete composite block and a production mould thereof. Background Art

[0002] Concrete blocks are man-made wall building materials made from cement as a binder, supplemented with aggregates such as sand, stone, and fly ash. These blocks are mixed, molded, and autoclaved for curing. Their standard dimensions are typically 390mm x 190mm x 190mm. Hollow or solid structures are available to meet varying load-bearing requirements. Hollow blocks are primarily used for infill walls in frame structures, while solid blocks are suitable for load-bearing walls.

[0003] A Chinese patent application with authorization publication number CN103171036B discloses a self-insulating concrete composite block mold, which includes a rectangular mold frame and a partition assembly placed in the mold frame for separation. The mold frame includes long side panels, short side panels, and a bottom panel. The side panels and the bottom panel are connected by hinges to form a flip structure, and the two adjacent side panels are fixedly connected by buckles; the partition assembly includes a long partition and a short partition. Sockets are provided at both ends of the long partition, and the long side panels are provided with plug-ins that cooperate with the sockets.

[0004] As mentioned in the above application, in the demoulding process of concrete blocks, existing block molds mostly use direct pull-out demoulding. The interface friction between the mold and the outer wall of the concrete may cause surface quality defects of the blocks. Specifically, when the demoulding device applies external force to separate the mold from the initial setting concrete, the interface friction effect generated by the contact surface of the two will form a shear stress field on the surface of the concrete. If this stress concentration phenomenon exceeds the early tensile strength threshold of the concrete, it will cause three types of typical damage on the surface: a microcrack network extending along the demoulding direction; a rough surface defect formed by local aggregate peeling; and deep penetrating cracks, which will affect the quality of the blocks and cause the production of defective products. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a self-insulating concrete composite building block manufacturing device and a production mold thereof.

The two groups of first linkage mechanisms are respectively connected to the two longitudinal mold frames, and the two groups of second linkage mechanisms are respectively connected to the transverse mold frames. When the upper mold base is driven to move upward, the two groups of first linkage mechanisms synchronously drive the two longitudinal mold frames to move away from each other. When the two longitudinal mold frames move away from each other, the two groups of second linkage mechanisms synchronously drive the two transverse mold frames to move away from each other, so that the molding unit is in an expanded state.

[0012] As a further description of the above technical solution: the first linkage mechanism includes a guide rail welded and fixed on the lower mold base and a sliding seat that can slide up and down on the guide rail, the sliding seat is rotatably connected to a connecting block through a pin shaft, and the other end of the connecting block is rotatably connected to the longitudinal mold frame through a pin shaft, wherein the guide rail is completed by connecting the lower vertical section, the arc section and the upper vertical section end to end.

[0013] As a further description of the above technical solution: the second linkage mechanism includes a first wedge-shaped block welded to the longitudinal mold frame and a second wedge-shaped block movably arranged on the upper mold base, and the second wedge-shaped block is fixedly connected to the transverse mold frame through an L-shaped connecting frame;

[0018] A self-insulating concrete composite block manufacturing device comprises a plurality of self-insulating concrete composite block production molds and a conveying assembly, wherein the plurality of self-insulating concrete composite block production molds are fixed to each other along the width to form an integrated structure of the device body;

[0022] Beneficial effects:

[0023] The production mold of a self-insulating concrete composite block provided by the present invention realizes the automated coordinated movement of the mold separation process through an innovative linkage design. When the block is formed, the upper mold base is driven to move upward. At this time, the two groups of first linkage mechanisms and the second linkage mechanism form a chain transmission system. First, the first linkage mechanism drives the two longitudinal mold frames to move away from each other. Then, the second linkage mechanism, triggered by the displacement of the longitudinal mold frame, drives the transverse mold frames to separate laterally synchronously. This process ultimately causes the molding unit as a whole to be in an expanded state, and a uniform gap is formed between the mold working surface and the block surface, effectively eliminating the surface friction caused by traditional direct-pull demoulding. By optimizing the mold's directional motion trajectory, the demoulding resistance is reduced, and the block edge breakage rate is significantly reduced. In addition, the linkage mechanism adopts a purely mechanical transmission method, and does not require an additional hydraulic or pneumatic drive unit, thereby saving costs and making the operation simpler.

[0024] Secondly, the molding unit has two working states. The first working state is that the molding unit is in a contracted state. At this time, it cooperates with the lower mold base to form a closed mold cavity for concrete block molding. The second working state is that the molding unit is in an expanded state. When in use, the first working state and the second working state can be automatically switched. When the molding unit is in an expanded state as a whole, a uniform gap is formed between the mold working surface and the block surface, effectively eliminating the surface friction caused by traditional direct pull-out demoulding. When the molding unit is in a contracted state, it cooperates with the lower mold base to form a closed mold cavity for block manufacturing. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific diagrams. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless they conflict.

[0038] Example 1

[0039] See also Figures 1-9 , an embodiment of the present invention provides a technical solution: a production mold for self-insulating concrete composite blocks, comprising an external frame 1, a lower mold base 2 and an upper mold base 3, wherein the lower mold base 2 is fixed inside the external frame 1, and the upper mold base 3 is movably arranged inside the external frame 1, and the upper mold base 3 is located above the lower mold base 2, and further comprising a molding unit 4 arranged on the lower surface of the upper mold base 3, the molding unit 4 having two working states, the first working state being that the molding unit 4 is in a contracted state, at which time it cooperates with the lower mold base 2 to form a closed mold cavity for concrete block molding, and the second working state being that the molding unit 4 is in an expanded state, at which time it is used for demolding the concrete block, reducing the friction resistance of demolding, and avoiding defects such as a microcrack network, pitting, or even through cracks on the surface of the block;

[0040] A linkage assembly is also provided on the upper die base 3. When the upper die base 3 is driven to move upward, the linkage assembly synchronously drives the molding unit 4 to switch from the first working state to the second working state.

[0041] The molding unit 4 includes two transverse mold frames 41 and two longitudinal mold frames 42;

[0042] A first support seat 411 is welded to the outer wall of the transverse mold frame 41. A transverse slider 412 is welded to the transverse mold frame 41. The transverse slider 412 is slidably connected to a transverse groove 414 provided on the lower surface of the upper mold base 3. A transverse spring 413 is welded to one side wall of the transverse slider 412.

[0043] A second support seat 421 is welded on the outer wall of the longitudinal mold frame 42, and a longitudinal slider 422 is welded on the longitudinal mold frame 42. The longitudinal slider 422 is slidably connected to the longitudinal slide groove 424 opened on the lower surface of the upper mold base 3, and a longitudinal spring 423 is welded on one side wall of the longitudinal slider 422.

[0044] Two first support frames 201 are welded on the upper surface of the lower mold base 2, and the inner walls of the two first support frames 201 abut against the second support base 421. A connecting support frame 202 is welded between the two first support frames 201, and a support block 203 is welded on the inner wall of the connecting support frame 202, and the support block 203 abuts against the first support base 411.

[0045] It should be noted that, in the initial state, under the push of the elastic force of the longitudinal spring 423 and the transverse spring 413, the two transverse mold frames 41 and the two longitudinal mold frames 42 are driven to splice with each other to form a complete rectangular frame structure to cooperate with the lower mold base 2 and the upper mold base 3 to form a closed mold cavity, and when the upper mold base 3 moves downward, it cooperates with the lower mold base 2 and the molding unit 4 to form a closed mold cavity, and cooperates with the first support frame 201, the connecting support frame 202 and the support block 203 set on the lower mold base 2, to support and limit the molding unit 4, thereby improving the strength of the complete rectangular frame formed by splicing the two transverse mold frames 41 and the two longitudinal mold frames 42 with each other; and when the building block is formed, when it reaches the point where the upper mold base 3 is controlled to move upward, the support block 203 is driven to be misaligned with the first support base 411 and the first support frame 201 and the second support base 421, at this time the two transverse mold frames 41 and the two longitudinal mold frames 42 can expand outward so that they do not contact the surface of the building block, thereby reducing the friction resistance of demolding.

[0046] The linkage assembly consists of two groups of first linkage mechanisms 5 and two groups of second linkage mechanisms 6. The two groups of first linkage mechanisms 5 are respectively connected to the two longitudinal mold frames 42, and the two groups of second linkage mechanisms 6 are respectively connected to the transverse mold frames 41. When the upper mold base 3 is driven to move upward, the two groups of first linkage mechanisms 5 synchronously drive the two longitudinal mold frames 42 to move away from each other. When the two longitudinal mold frames 42 move away from each other, the two groups of second linkage mechanisms 6 synchronously drive the two transverse mold frames 41 to move away from each other, so that the molding unit 4 is in an expanded state.

[0047] The first linkage mechanism 5 includes a guide rail 51 welded and fixed on the lower mold base 2 and a sliding base 52 that can slide up and down on the guide rail 51. The sliding base 52 is rotatably connected to a connecting block 53 through a pin shaft. The other end of the connecting block 53 is rotatably connected to the longitudinal mold frame 42 through a pin shaft. The guide rail 51 is completed by the end-to-end connection of the lower vertical section 511, the arc section 512 and the upper vertical section 513.

[0048] The second linkage mechanism 6 includes a first wedge block 61 welded to the longitudinal mold frame 42 and a second wedge block 62 movably arranged on the upper mold base 3. The second wedge block 62 is fixedly connected to the transverse mold frame 41 via an L-shaped connecting frame 65.

[0049] A connecting slider 63 is welded to the upper surface of the second wedge block 62 , and the connecting slider 63 is slidably connected to a connecting slot 66 opened on the lower surface of the upper die base 3 . A return spring 64 is welded to one side wall of the connecting slider 63 .

[0050] Specifically, the working method of the linkage assembly is as follows: when the upper mold base 3 is driven to move upward, the sliding base 52 is driven to move upward on the guide rail 51. In the initial stage, when the sliding base 52 moves on the lower vertical section 511, it will not drive the longitudinal mold frame 42 to move outward. Therefore, the longitudinal mold frame 42 will also be abutted and limited by the first support frame 201 so that it cannot move.

[0051] As the upper mold base 3 continues to move upward, the first support frame 201 and the second support base 421 are displaced from each other. At this time, the sliding base 52 also moves to the arc segment 512. Through the change in the position of the sliding base 52, the connecting block 53 pulls the longitudinal mold frame 42 outward, and the two sets of first linkage mechanisms 5 drive the two longitudinal mold frames 42 to move away from each other.

[0052] When the two longitudinal mold frames 42 move away from each other, the two sets of second linkage mechanisms 6 synchronously drive the two transverse mold frames 41 to move away from each other. The specific working method is as follows: when the longitudinal mold frames 42 move outward, the first wedge block 61 is driven to move, and the movement of the first wedge block 61 pushes the second wedge block 62 to move. The second wedge block 62 drives the connecting slider 63 to move in the connecting slide groove 66, so that the return spring 64 is squeezed and contracted. The second wedge block 62 drives the transverse mold frame 41 outward through the L-shaped connecting frame 65, and the two transverse mold frames 41 are synchronously driven to move away from each other by the two sets of second linkage mechanisms 6.

[0053] In this embodiment, the automated coordinated movement of the mold separation process is achieved through an innovative linkage design. When the block is formed, the upper mold base 3 is driven to move upward. At this time, the two groups of first linkage mechanisms 5 and second linkage mechanisms 6 form a chain transmission system. First, the first linkage mechanism 5 drives the two longitudinal mold frames 42 to move away from each other. Then, the second linkage mechanism 6 is triggered by the displacement of the longitudinal mold frame 42 to drive the transverse mold frame 41 to separate laterally. This process eventually makes the molding unit 4 as a whole expand, and a uniform gap is formed between the mold working surface and the block surface, effectively eliminating the surface friction caused by traditional direct pull-out demolding. By optimizing the mold directional motion trajectory, the demolding resistance is reduced, and the block edge breakage rate is significantly reduced. The linkage mechanism adopts a purely mechanical transmission method, and there is no need for additional hydraulic or pneumatic drive units, which saves costs and makes operation simpler.

[0054] An upper slider 301 is welded to the upper mold base 3, and the upper slider 301 is slidably connected to the strip slide 12 opened on the external frame 1. A hydraulic telescopic rod 302 is installed on the top crossbeam of the external frame 1, and the bottom end of the hydraulic telescopic rod 302 is fixedly connected to the upper mold base 3.

[0055] A feed pipe 303 is connected to the center of the upper surface of the upper mold base 3 , and concrete is poured through the feed pipe 303 . A rectangular through hole 501 is opened on the upper mold base 3 to cooperate with the guide rail 51 .

[0056] Specifically, in this embodiment, the upper mold base 3 is slidably connected to the strip slide 12 opened on the external frame 1 through the upper slider 301, so that the upper mold base 3 can move up and down in the external frame 1, driving the molding unit 4 to adjust its position. The hydraulic telescopic rod 302 is a power element, which is used to drive the upper mold base 3 to adjust its height.

[0059] A rectangular groove 211 is formed on the lower die base 2 of the multiple production dies. The multiple rectangular grooves 211 are interconnected to form a conveying channel, and the conveying assembly is arranged in the conveying channel.

[0060] The conveying assembly includes a roller shaft 71 fixed to both ends of the equipment body 7 along the length direction through a bracket and a conveyor belt 72 wrapped around the roller shaft 71.

[0061] A plurality of grooves are indirectly formed on the upper surface of the conveyor belt 72 , and a supporting plate 73 is clamped in the groove. A limiting frame 74 is fixed at the corners of the upper surface of the supporting plate 73 .

[0062] Specifically, the limit frame 74 is adapted to the molding unit 4, that is, the limit frame 74 can be mounted on the outside of the molding unit 4 to further position the molding unit 4 and improve the strength of the molding unit 4 after shrinkage. Moreover, through the setting of the rectangular groove 211 and the support plate 73, when in use, when the upper mold base 3 is controlled to move downward, the bottom end of the molding unit 4 is adjusted to abut against the support plate 73. At this time, the limit frame 74 on the outside of the support plate 73 will be mounted on the outside of the molding unit 4 to assist in limiting the molding unit 4.

[0063] Specifically, through the setting of the rectangular groove 211 and the conveyor belt 72, when the building blocks are formed, they can be transported to one end of the equipment body 7 through the conveyor block for unloading, making it more convenient to unload. Further, with the opening of the groove and the setting of the support plate 73, the formed building blocks can be transferred through the support plate 73, further improving the convenience of its transfer and reducing the generation of defective blocks during the transfer process.
