Description

Technical Field

[0001] This utility model relates to the field of composite brick technology, and in particular to an extrusion mold for the block matrix in composite bricks. Background Technology

[0002] Modular bricks are composite components made of a block base (bricks / blocks) and reinforcing materials (reinforced concrete, fireproof and thermal insulation materials, etc.). This relates to another patent filed by the applicant, a type of modular brick, such as... Figure 1 As shown, the composite brick includes two opposing block bases. The middle of the block base has a through hole, which serves as a pouring channel for communication between the upper and lower composite bricks. Both sides of the block base have groove-like structures, which allow the opposing block bases to be locked together by connectors. Due to the structure of the block base, a specific mold is required for molding.

[0003] For example, Chinese invention patent with authorization announcement number "CN109605553B" discloses a mold for preparing building construction composite bricks and its preparation method. The mold comprises an upper template, a first forming plate, a second forming plate, a lower template, a guide pipe, a multi-stage hydraulic cylinder, a groove forming boss, a bottom forming block, a lower grout tank forming plate, a sliding limiting groove, a guide grout tank forming platform, an upper grout tank forming plate, a hollow channel forming column, a connecting groove forming block, a first sliding plate, and a second sliding plate. In use, release coating is first sprayed onto the forming surfaces of each template. Then, the first and second forming plates are closed by the multi-stage hydraulic cylinder, closing the upper and lower templates. Subsequently, the material is fed through the guide pipe... Concrete is poured between the upper and lower formwork and left to stand for a period of time until it solidifies. Then, the upper and lower formwork are opened, and the first and second forming plates are opened using multi-stage hydraulic cylinders. A composite brick is formed between two adjacent first forming plates. However, during demolding and unloading, since each composite brick is placed on the lower formwork and located in the forming space between two adjacent first forming plates, workers need to use a clamping device to reach into the forming space between the two adjacent first forming plates to clamp and unload the composite bricks one by one. When dealing with the mass production of composite bricks by manufacturing enterprises, this demolding and unloading method has low work efficiency and high labor intensity for workers. Summary of the Invention

[0004] In view of this, it is necessary to provide an extrusion die for the block matrix in composite bricks to solve the technical problem that when manufacturing enterprises mass-produce composite bricks, workers need to clamp and unload the block matrix of the composite bricks one by one, which leads to high labor intensity and low work efficiency for workers.

[0005] This utility model provides an extrusion mold for a block matrix in composite brickwork, comprising a mold body, a demolding assembly, a receiving base plate, and a through-hole forming column assembly. Multiple extrusion channels are vertically formed within the mold body, each adapting to the outer contour of the block matrix. The demolding assembly is located above the mold body, while the receiving base plate and the through-hole forming column assembly are located below the mold body, with the receiving base plate positioned between the mold body and the through-hole forming column assembly. Multiple sets of through holes are formed on the receiving base plate, each corresponding to one of the multiple extrusion channels. The upper part of the through-hole forming column assembly passes through the multiple sets of through holes and inserts into the multiple extrusion channels, such that the upper surface of the receiving base plate and the upper part of the through-hole forming column assembly are aligned... A plurality of forming spaces for the block substrates are formed between the inner wall of the extrusion channel and the forming slurry. The forming slurry is injected into the forming spaces of the block substrates through the upper end of the extrusion channel to form a plurality of block substrates. The bottom of the demolding component is inserted into the forming spaces of the block substrates and presses the block substrates downward to demold. The block substrates press the receiving base plate downward, and at the same time, the receiving base plate presses the through-hole forming column assembly downward to pull out the extrusion channel, so that the block substrates are inserted into the through-hole forming column assembly and placed on the receiving base plate. By lifting the receiving base plate on the through-hole forming column assembly, the receiving base plate drives the block substrates to be pulled out of the through-hole forming column assembly to complete the unloading.

[0006] Preferably, the demolding assembly includes a first support plate and multiple block substrate samples. The multiple block substrate samples are vertically fixed to the lower surface of the first support plate, and the multiple block substrate samples correspond one-to-one with the multiple extrusion channels, so that the first support plate drives the multiple block substrate samples to be inserted into the molding space of the multiple block substrates respectively, pressing the multiple block substrates downward to demold.

[0007] Preferably, the first support plate is further provided with multiple sets of discharge through holes, which correspond to the through holes of multiple block substrate samples. The block substrate samples are inserted into the molding space of the block substrate to press the block substrate downward for demolding. The upper part of the through hole molding column assembly is in the through hole penetrating the block substrate to push excess molding slurry out through the discharge through hole.

[0008] Preferably, the through-hole forming column assembly includes a second support plate and multiple sets of through-hole forming columns. The multiple sets of through-hole forming columns are vertically fixed to the upper surface of the second support plate, and the multiple sets of through-hole forming columns correspond one-to-one with the multiple sets of through holes. The second support plate drives the multiple sets of through-hole forming columns to pass through the multiple sets of through holes and insert into multiple extrusion channels, so that multiple forming spaces for the block substrate are formed between the upper surface of the receiving base plate, the through-hole forming columns, and the inner wall of the extrusion channels. Furthermore, by lifting the receiving base plate on the through-hole forming column assembly, the multiple block substrates are extracted from the through-hole forming columns to complete the unloading.

[0009] Preferably, installation guide protrusions and filling guide protrusions are vertically arranged on the opposite inner walls of the extrusion channel, and the block substrate forms an installation groove on its inner end face under the guidance of the installation guide protrusions, and the block substrate forms a slurry filling groove on its outer end face under the guidance of the filling guide protrusions.

[0010] Preferably, the top width of the mounting guide protrusion is greater than the bottom width.

[0011] Preferably, the filling guide protrusion includes a plurality of first guide protrusions and a plurality of second guide protrusions, the widths of the first guide protrusions and the second guide protrusions being different, and the first guide protrusions and the second guide protrusions being staggered.

[0012] Preferably, the two extrusion channels are a group, and the two extrusion channels are opened opposite each other on the mold body, so that the two block bases extruded by each group of extrusion channels can be locked together by the connector to form a composite brick.

[0013] As can be seen from the above technical solution, the extrusion mold for the block matrix in the composite brick provided by this utility model includes a mold body, a demolding component, a receiving base plate, and a through-hole forming column component. Multiple extrusion channels are vertically opened in the mold body. The extrusion channels are adapted to the outer contour of the block matrix. The demolding component is located above the mold body. The receiving base plate and the through-hole forming column component are both located below the mold body. The receiving base plate is located between the mold body and the through-hole forming column component. Multiple sets of through holes are opened on the receiving base plate. The multiple sets of through holes correspond to multiple extrusion channels respectively.

[0014] In the mass production of block substrates, workers first insert the upper part of the through-hole forming column assembly through multiple sets of through holes into multiple extrusion channels. This creates forming spaces for multiple block substrates between the upper surface of the receiving base plate, the upper part of the through-hole forming column assembly, and the inner wall of the extrusion channels. Then, molding slurry is injected into these forming spaces through the upper end of the extrusion channels to form multiple block substrates. When demolding the block substrates, workers insert the bottom of a demolding component into the forming spaces, pressing the block substrates downwards. Each block substrate presses down on the receiving base plate, causing it to move downwards. The pressing through-hole forming column assembly moves downward to extract the extrusion channel, so that multiple block substrates are inserted into the through-hole forming column assembly and placed on the receiving base plate. When unloading the multiple block substrates inserted into the through-hole forming column assembly, the worker can lift the receiving base plate on the through-hole forming column assembly, so that the receiving base plate drives the multiple block substrates to be pulled out of the through-hole forming column assembly to complete the unloading. In this way, the extrusion mold provided by this utility model can not only form multiple block substrates, but also press out and unload multiple formed block substrates from their respective forming spaces at one time, thereby reducing the labor intensity of the workers and improving work efficiency.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Please refer to Figures 1 to 6 This utility model provides an extrusion mold 10 for the block matrix in a composite brick, including a mold body 110, a demolding component 120, a receiving base plate 130, and a through-hole forming column component 140. Multiple extrusion channels 111 are vertically opened inside the mold body 110. The extrusion channels 111 are adapted to the outer contour of the block matrix. The demolding component 120 is located above the mold body 110. The receiving base plate 130 and the through-hole forming column component 140 are both located below the mold body 110, and the receiving base plate 130 is located between the mold body 110 and the through-hole forming column component 140. Multiple sets of through holes 131 are opened on the receiving base plate 130, and the multiple sets of through holes 131 correspond to the multiple extrusion channels 111 respectively.

[0026] In the mass production of block substrates, the operator first inserts the upper part of the through-hole forming column assembly 140 through multiple sets of through holes 131 into multiple extrusion channels 111, so that multiple block substrate forming spaces are formed between the upper surface of the receiving base plate 130, the upper part of the through-hole forming column assembly 140, and the inner wall of the extrusion channel 111. Then, the forming slurry is injected into the multiple block substrate forming spaces through the upper end of the extrusion channel 111 to form multiple block substrates. When demolding the multiple block substrates, the operator inserts the bottom of the demolding assembly 120 into the multiple block substrate forming spaces, pressing the multiple block substrates downwards for demolding. The multiple block substrates press the receiving base plate 130 downwards, and simultaneously... The pressure-driven through-hole forming column assembly 140 moves downward to extract the extrusion channel 111, so that multiple block substrates are inserted into the through-hole forming column assembly 140 and placed on the receiving base plate 130. When unloading the multiple block substrates inserted into the through-hole forming column assembly 140, the worker can lift the receiving base plate 130 on the through-hole forming column assembly 140, so that the receiving base plate 130 drives the multiple block substrates to be extracted from the through-hole forming column assembly 140 to complete the unloading. In this way, the extrusion mold provided by this utility model can not only form multiple block substrates, but also press out and unload multiple formed block substrates from their respective forming spaces at one time, thereby reducing the labor intensity of the workers and improving work efficiency.

[0027] Furthermore, to ensure the integrity of the block substrate during demolding and reduce damage, the demolding assembly 120 includes a first support plate 121 and multiple block substrate samples 122. The multiple block substrate samples 122 are vertically fixed to the lower surface of the first support plate 121, and each block substrate sample 122 corresponds one-to-one with a multiple extrusion channel 111. This allows the first support plate 121 to drive the multiple block substrate samples 122 to be inserted into the molding space of the multiple block substrates, pressing the multiple block substrates downwards for demolding. The shape of the block substrate samples 122 matches the molding space of the block substrate, and the block substrate samples 122 are perpendicular to the block substrate. The pressure applied by the body actually acts as a "male mold," which ensures that the block substrate moves smoothly along the extrusion channel 111 during demolding. This greatly reduces the damage, cracking, or deformation of the block substrate edges and corners caused by uneven force, skewing, or friction. At the same time, multiple block substrate samples 122 are integrated on the first support plate 121, which not only allows multiple pre-formed block substrates to be extruded from their respective forming spaces at once, greatly improving production efficiency and avoiding the tedious and time-consuming process of demolding one by one, but also makes it very easy to automate the demolding process, as the entire demolding action is driven by the single vertical movement of the first support plate. This avoids uneven force caused by manual intervention.

[0028] Furthermore, in order to simultaneously remove excess slurry remaining in the through holes of the block substrate during the demolding process, ensure the integrity of its through hole structure and improve the smoothness of demolding, multiple sets of discharge through holes 1211 are also provided on the first support plate 121. The multiple sets of discharge through holes 1211 correspond to the through holes of multiple block substrate samples 122. The block substrate samples 122 are inserted into the molding space of the block substrate and press the block substrate downward to demold. The upper part of the through hole molding column assembly 140 is in the through hole penetrating the block substrate, so as to push the excess molding slurry out through the discharge through hole 1211.

[0029] Furthermore, the through-hole forming column assembly 140 includes a second support plate 141 and multiple sets of through-hole forming columns 142. The multiple sets of through-hole forming columns 142 are vertically fixed to the upper surface of the second support plate 141, and each set of through-hole forming columns 142 corresponds one-to-one with a set of through holes 131. The second support plate 141 drives the multiple sets of through-hole forming columns 142 to pass through the multiple sets of through holes 131 and insert into multiple extrusion channels 111, thereby forming multiple block matrix forming spaces between the upper surface of the receiving base plate 130, the through-hole forming columns 142, and the inner wall of the extrusion channels 111. By lifting the base plate 130 onto the through-hole forming column assembly 140, multiple block substrates are pulled out of the through-hole forming column 142 to complete unloading. Compared with the prior art method of pulling the column out of the through hole for demolding and unloading, the through-hole forming column 142 of this utility model is fixed to the second support plate 141, and the base plate 130 lifts the block substrate, so that the block substrate actively detaches from the stationary through-hole forming column 142. This transfers the stress point of demolding and unloading from the fragile through hole to the bottom of the block substrate and the base plate 130, effectively reducing the risk of damage to the through hole.

[0030] Furthermore, in order to form a functional structure of the block substrate in one step, installation guide protrusions 1111 and filling guide protrusions 1112 are vertically arranged on the inner walls of the extrusion channel 111. Under the guidance of the installation guide protrusions 1111, the block substrate forms an installation groove on its inner end face, and under the guidance of the filling guide protrusions 1112, the block substrate forms a slurry filling groove on its outer end face.

[0031] Furthermore, the top width of the mounting guide protrusion 1111 is greater than the bottom width, so that the opening width of the mounting groove is less than the bottom width, thereby preventing the connector from falling off the opening of the mounting groove.

[0032] Furthermore, the filling guide protrusion 1112 includes a plurality of first guide protrusions 11121 and a plurality of second guide protrusions 11122. The first guide protrusions 11121 and the second guide protrusions 11122 have different widths, and the first guide protrusions 11121 and the second guide protrusions 11122 are staggered so that the slurry filling groove has different groove widths and is also staggered, thereby enhancing the anchoring strength of the slurry.

[0033] Furthermore, to avoid the need for workers to move two heavy masonry blocks closer together and precisely adjust their positions to form a composite brick 20, this invention also uses two extrusion channels 111 as a group, with the two extrusion channels 111 being opened opposite each other on the mold body 110. This allows the two masonry blocks extruded by each group of extrusion channels 111 to be directly locked together by connectors to form a composite brick 20. Therefore, there is no need to manually move and adjust the position of the two masonry blocks. Workers only need to insert the connectors into the opposite sides of the two masonry blocks to form a composite brick 20.

[0034] The specific usage process of the extrusion die 10 for the block matrix in composite bricks is as follows:

[0035] First, workers can lift the second support plate 141, causing it to drive multiple sets of through-hole forming columns 142 through multiple sets of through holes 131 and insert them into multiple extrusion channels 111. This creates a forming space for multiple block substrates between the upper surface of the base plate 130, the through-hole forming columns 142, and the inner wall of the extrusion channels 111. Then, the forming slurry is injected into the forming space of the multiple block substrates through the upper end of the extrusion channels 111 to form multiple block substrates for molding.

[0036] When demolding is required, the worker can press the first support plate 121, causing it to pull multiple block substrate samples 122 into the molding spaces of multiple block substrates, pressing the multiple block substrates downwards for demolding. Excess slurry remaining in the through holes of the block substrates is discharged through the discharge through holes 1211, and multiple block substrates press the receiving base plate 130 downwards. Simultaneously, the receiving base plate 130 presses the second support plate 141 downwards, and the through-hole molding column 142 is pulled out of the extrusion channel 111, so that multiple block substrates are inserted into the through-hole molding column 142 and placed on the receiving base plate 130. When unloading the multiple block substrates inserted into the through-hole molding column 142, the worker can lift the receiving base plate 130, causing it to pull the multiple block substrates out of the through-hole molding column assembly 140, thus completing the unloading.

[0037] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
