Description

Technical Field

[0001] The present invention relates to the field of energy-saving building material production, specifically to the field of concrete cover plate production, and particularly to a forming mold for concrete cover plate production. Background Art

[0002] Concrete cover plates are a common type of building material. Traditional concrete cover plate production relies on cement. However, with the development of the concept of green environmental protection, concrete cover plates are gradually developing towards energy-saving building materials. For example, green concrete (incorporating industrial wastes such as fly ash, slag, and silica fume to reduce cement usage), low-carbon cement (using sulfoaluminate cement or carbon-cured cement), phase change concrete slabs (embedded with phase change materials such as paraffin to absorb heat and regulate room temperature), and so on.

[0003] During the production of energy-saving concrete slabs, it includes a forming process, that is: after mixing raw materials such as cement and aggregates, it is fed into a forming mold, then vibrated and compacted and waited to form, and after forming, demolding can obtain the concrete slab; there are some deficiencies in this forming method. For example, when mixing raw materials, water needs to be added. As is well known, when the stirred cement stands still, it will show a layering phenomenon, that is, it is thinner on the upper part and thicker on the lower part, and the longer the standing time, the more obvious this phenomenon is. Therefore, during forming, in the path from the stirred cement to the forming mold, the cement is not stirred, which is equivalent to standing still. Therefore, during the process of filling the forming mold with cement from zero to full, the cement is prone to layering, resulting in relatively poor quality of the formed concrete.

[0004] Based on the above, the present invention proposes a forming mold for concrete cover plate production. Summary of the Invention

The upper end of the upper guide rod is slidably arranged in the upper guide sleeve.

[0010] As a further improvement and optimization of the present invention, a lower sealing column is sleeved in the lower inlet pipe. The bottom of the lower sealing column extends out of the lower inlet pipe and is provided with a lower lug. The lower surface of the lower lug contacts the fixed die base; A lower spring is arranged between the bottom of the lower sealing column and the fixed die. Initially, under the support of the lower spring, the upper surface of the lower sealing column is located below the upper side hole.

[0011] As a further improvement and optimization of the present invention, an upper sealing column is sleeved in the upper inlet pipe. The upper end of the upper sealing column extends out of the upper inlet pipe and is provided with an upper lug. The upper surface of the upper lug contacts the moving die base; An upper spring is arranged between the upper end of the upper sealing column and the moving die. Initially, under the support of the upper spring, the lower surface of the upper sealing column is located above the upper side hole.

[0012] As a further improvement and optimization of the present invention, the connecting guide column forms a sliding connection with the fixed die and forms a sliding connection with the moving die. A limiting ring is arranged at the upper end of the connecting guide column. A connecting spring located between the fixed die and the moving die is sleeved outside the connecting guide column; The elastic coefficient of the connecting spring is greater than that of the upper spring, and the elastic coefficient of the connecting spring is greater than that of the lower spring.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The concrete cover slab forming process of this scheme includes the feeding stage and the forming stage, in which: 1. In the feeding stage, the cement raw materials are pulled into the mold cavity of the fixed mold by the supply member. Specifically, a part of the cement raw materials flows into the mold cavity of the fixed mold through the lower side tube, the lower side hole, the lower inlet tube, and the lower inlet, and another part of the cement raw materials falls into the mold cavity of the fixed mold through the upper side tube, the upper side hole, the upper inlet tube, and the upper inlet. Therefore, during the feeding process, the two parts of cement will collide and impact with each other, which has a stirring effect, that is, in the production process of the concrete cover plate, except for the final vibration molding step, the cement raw materials are stirring until the feeding, so the composition distribution of the concrete cover plate finally produced is balanced and the quality is higher; Second, in the molding stage, the upper side hole, upper inlet, lower side hole and lower inlet are sealed by the cooperation of the upper sealing column and the lower sealing column before molding begins. The advantages are: If there is no lower sealing column, the bottom of the formed concrete cover plate will become a convex column, which will affect the forming quality of the concrete cover plate. If there is no upper sealing column, then during the molding process: on the one hand, since the orifice of the upper side hole is not blocked, the cement raw material in the upper side tube can easily fall into the upper surface of the concrete cover plate being molded during molding, and the time of falling is uncertain, so there is a bulge on the upper surface of the concrete cover plate after molding, affecting the molding quality of the concrete cover plate; on the other hand, when the cement raw material in the mold cavity is compacted by inserting the movable mold into the mold cavity of the fixed mold, part of the water in the cement raw material will be squeezed out, which not only easily causes the water to flow back into the upper inlet, thereby affecting the molding of the cement raw material located below the upper inlet, but also easily leaves a mark on the upper surface of the molded concrete cover plate that matches the lower orifice of the upper inlet, affecting the molding quality of the concrete cover plate; On the contrary, with the existence of upper sealing columns and lower sealing columns, the above-mentioned problem of affecting the molding quality of the concrete cover slab does not exist.

[0025] A lower sealing column 304 is sleeved inside the lower inlet pipe. The bottom of the lower sealing column 304 extends out of the lower inlet pipe and is provided with a lower lug 3041, and the lower surface of the lower lug 3041 contacts the fixed mold base 301.

[0026] A lower spring 305 is provided between the bottom of the lower sealing column 304 and the fixed mold 302. Initially, under the support of the lower spring 305, the upper surface of the lower sealing column 304 is located below the lower side hole.

[0027] Refer to Figure 5 And Figure 7 , the moving mold assembly 200 is located above the fixed mold assembly 300.

[0028] The moving mold assembly 200 includes a moving mold base 202 and a moving mold 201 located below the moving mold base 202, and the two form a sliding connection in the vertical direction. Further, a vertically arranged upper guide sleeve 2021 is provided on the lower surface of the moving mold base 202, a vertically arranged upper guide rod 2011 is provided on the upper surface of the moving mold 201, and the upper end of the upper guide rod 2011 is slidably arranged in the upper guide sleeve 2021.

[0029] The lower surface of the moving mold 201 is horizontally arranged, and an upper inlet 203 is penetrated and opened at the middle position of the lower surface of the moving mold 201. An upper inlet pipe is provided at the upper orifice of the upper inlet 203. An upper side hole is opened on the side surface of the upper inlet pipe. An upper side pipe 206 is provided at the orifice of the upper side hole, and the end of the upper side pipe 206 is connected to the supply member.

[0030] An upper sealing column 204 is sleeved inside the upper inlet pipe. The upper end of the upper sealing column 204 extends out of the upper inlet pipe and is provided with an upper lug 2041, and the upper surface of the upper lug 2041 contacts the moving mold base 202.

[0031] An upper spring 205 is provided between the upper end of the upper sealing column 204 and the moving mold 201. Initially, under the support of the upper spring 205, the lower surface of the upper sealing column 204 is located above the upper side hole.

[0032] Refer to Figure 5 With Figure 6 , the connecting guide post 400 and the fixed mold 302 are slidably connected, the connecting guide post 400 and the movable mold 201 are slidably connected, a limit ring is provided at the upper end of the connecting guide post 400, and a connecting spring 401 located between the fixed mold 302 and the movable mold 201 is sleeved outside the connecting guide post 400.

[0033] The working process of the forming mold is specifically shown as follows: Feeding stage: The cement raw materials are drawn into the cavity of the fixed mold 302 through the supply member. Specifically, a part of the cement raw materials pour into the cavity of the fixed mold 302 through the lower side pipe 306, the lower side hole, the lower inlet pipe, and the lower inlet 303. Another part of the cement raw materials fall into the cavity of the fixed mold 302 through the upper side pipe 206, the upper side hole, the upper inlet pipe, and the upper inlet 203. Therefore, during this feeding process, the two parts of cement will collide and impact with each other, achieving a stirring effect. That is, during the production process of the concrete cover plate, except for the final vibration forming step, the cement raw materials are constantly stirred until the feeding process. Therefore, the component distribution of the finally produced concrete cover plate is balanced and the quality is higher.

[0034] Forming stage: After the feeding is completed, the movable mold base 202 is driven to move downward through the existing hydraulic technology. During this process: At the beginning, since the elastic coefficient of the connecting spring 401 is much larger than that of the upper spring 205, when the movable mold base 202 moves downward, it drives the upper sealing post 204 to move downward together through the upper lug 2041. The upper side hole is sealed by the upper sealing post 204. When the lower surface of the upper sealing post 204 is flush with the lower surface of the movable mold 201, the lower surface of the movable mold 201 can form a complete flat shape. At this time, the displacement of the upper guide rod 2011 in the upper guide sleeve 2021 reaches the maximum, and the upper sealing post 204 is restricted and cannot continue to move downward with the movable mold 201 as a reference point; After that, the movable mold base 202 moves downward and drives the entire movable mold assembly 200 to move downward together. Since the elastic coefficient of the connecting spring 401 is much larger than that of the lower spring 305, the movable mold assembly 200 pushes the fixed mold 302 to move downward through the connecting spring 401. Due to the contact between the lower lug 3041 and the fixed mold base 301, the downward movement of the lower sealing post 304 is restricted. Therefore, with the fixed mold 302 as a reference point, the lower sealing post 304 moves upward to block the lower side hole, and finally the upper surface of the lower sealing post 304 is flush with the bottom of the cavity of the fixed mold 302, making the bottom of the cavity form a complete flat shape. At this time, the displacement of the lower guide rod 3021 in the lower guide sleeve 3011 reaches the maximum, and the lower sealing post 304 is restricted and cannot continue to move upward with the fixed mold 302 as a reference point; After that, the moving die holder 202 continues to move downward as a whole with the moving die assembly 200, so that the moving die 201 is inserted into the mold cavity of the fixed die 302, compressing the cement raw materials in the mold cavity, and the connecting spring 401 is compressed; After a preset time, the forming is completed. By means of the existing hydraulic technology, the moving die holder 202 is driven to move upward to realize mold opening, and the concrete cover plate is taken away; During the forming stage, the existence of the upper sealing column 204 and the lower sealing column 304 has the following advantages: Without the lower sealing column 304, the bottom of the formed concrete cover plate will form a convex column, which affects the forming quality of the concrete cover plate; Without the upper sealing column 204, during the forming process: on the one hand, since the orifice of the upper side hole is not blocked, when forming, the cement raw materials in the upper side pipe 206 are very likely to fall onto the upper surface of the concrete cover plate being formed, and the falling time is uncertain. Therefore, there are protrusions on the upper surface of the formed concrete cover plate, which affects the forming quality of the concrete cover plate; on the other hand, when the moving die 201 is inserted into the mold cavity of the fixed die 302 to compact the cement raw materials in the mold cavity, some of the moisture in the cement raw materials will be squeezed out. This not only easily causes the moisture to flow back into the upper inlet 203, thus affecting the forming of the cement raw materials located below the upper inlet 203, but also easily leaves a mark on the upper surface of the formed concrete cover plate that matches the lower orifice of the upper inlet 203, affecting the forming quality of the concrete cover plate; On the contrary, the existence of the upper sealing column 204 and the lower sealing column 304 does not have the above-mentioned problems that affect the forming quality of the concrete cover plate.

[0035] In a preferred embodiment, vibrators are provided on both the moving die 201 and the fixed die 302 to improve the compaction effect when compacting the cement raw materials in the mold cavity.

[0036] In a preferred embodiment, a water receiving box 307 is provided on the outer surface of the fixed die 302. A drain pipe 3071 is provided at the bottom of the water receiving box 307. After the moisture generated by compaction penetrates out, it falls into the water receiving box 307 and is discharged through the drain pipe 3071.

[0037] II. Supply component: Referring to Figures 2-4 , the supply component includes a storage tank 100. The storage tank 100 is used to receive the stirred and mixed cement raw materials. Obtaining the cement raw materials by stirring and mixing the raw materials is achievable by existing technologies and will not be elaborated here.

[0038] A feeding component 101 is provided at the bottom of the storage tank 100. Specifically, the feeding component 101 includes a horizontally arranged feeding pipe 1011. An upper connecting nozzle is provided at the highest point of the outer circumferential surface of the feeding pipe 1011, and the upper connecting nozzle is connected to the bottom of the storage tank 100.

[0039] A piston 1012 is sleeved inside the feeding pipeline 1011, and the piston 1012 is driven by a telescopic rod 1013 to move inside the feeding pipeline 1011.

[0040] The output end of the feeding pipeline 1011 is provided with a main pipeline 102, and the end of the main pipeline 102 is provided with two branch pipelines 103. The ends of the two branch pipelines 103 are respectively connected to the upper side pipe 206 and the lower side pipe 306.

[0041] In this solution, the telescopic rod 1013 is used to drive the piston 1012 to move, so that the upper nozzle is opened, and the cement raw materials in the storage tank 100 fall into the feeding pipeline 1011. After a preset time, the piston 1012 moves in the reverse direction to block the upper nozzle, and continues to move to push the cement raw materials in the feeding pipeline 1011. The cement raw materials are sent into the forming die through the main pipeline 102 and the two branch pipelines 103.

[0042] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
