Abstract

This invention discloses an energy-saving lightweight precast concrete component molding equipment, belonging to the field of concrete molding technology. It includes a molding mechanism for casting precast concrete components, an application mechanism for applying a release agent, and a removal mechanism for removing the molded precast concrete component. The application mechanism automatically flips and attaches the side and bottom templates to a rotating application wheel during demolding, achieving uniform and quantitative application of the release agent. This replaces inefficient and inconsistent manual application, improving efficiency, ensuring a smooth component surface, reducing release agent waste, and being more energy-efficient and environmentally friendly. The removal mechanism, driven by a single bottom electric cylinder, simultaneously completes the opening of the side templates, the lifting and demolding of the component, and the receiving and lowering of the finished product, all without manual intervention.

Description

Technical Field

[0001] This invention relates to the field of concrete molding technology, and in particular to an energy-saving lightweight precast concrete component molding equipment. Background Technology

[0002] Against the backdrop of rapid development in building industrialization and prefabricated construction, precast concrete components are widely used in various building projects due to their advantages such as fast construction speed, stable quality, energy saving, and environmental protection. Lightweight precast concrete components, with their low density, excellent thermal insulation performance, and ability to effectively reduce structural weight, are particularly favored in modern architecture.

[0003] However, several technical problems remain to be solved in the traditional production process of lightweight precast concrete components. First, the application of release agent to molds mostly relies on manual operation or simple mechanical assistance, which is not only inefficient and difficult to guarantee uniform application, but also results in significant waste of release agent and affects the working environment. Second, the demolding and removal process after component molding usually requires the cooperation of multiple people, has a low degree of automation, poses safety hazards, and is prone to causing bumps and damage to the edges of components during demolding. In addition, traditional molding equipment has poor control over mold closing and sealing during concrete pouring, which can easily lead to concrete slurry leakage, affecting the quality of component molding and the on-site working environment. At the same time, air bubbles inside the mold are difficult to remove effectively, which can easily cause porosity defects on the surface of the component.

[0004] Currently, some automated molding equipment on the market attempts to solve some of the above problems, but they are often complex in structure, have high energy consumption, or only make automation improvements for a single process, failing to integrate and coordinate processes such as release agent application, concrete pouring and compaction, and component demolding. This results in large equipment footprint, high energy consumption, cumbersome operation procedures, and poor coordination between various mechanisms, making it impossible to achieve efficient, energy-saving, and high-quality continuous production.

[0005] Therefore, developing a lightweight precast concrete component molding equipment that integrates functions such as automatic application of release agent, sealed concrete pouring and venting, and automatic demolding and removal of molded components, and is compact, energy-efficient, and highly effective, is of great practical significance for improving the automation level of precast component production, ensuring component quality, and reducing production costs and energy consumption. Summary of the Invention

[0006] To address the aforementioned technical problems, the present invention adopts the following technical solution: an energy-saving lightweight precast concrete component forming equipment, comprising a forming mechanism for casting precast concrete components, the forming mechanism comprising a main frame, and the forming mechanism being provided with an application mechanism for applying a release agent and an extraction mechanism for removing the formed precast concrete component. The coating mechanism includes a lower limit plate fixedly installed on the main frame, two side bottom templates slidably installed on the lower limit plate, the lower surfaces of the two side bottom templates are in contact, a horizontal sliding column is fixedly installed on the side bottom template, and a movable frame is slidably installed on the horizontal sliding column.

[0007] Furthermore, the forming mechanism includes an opening and closing electric cylinder fixedly installed on the main frame. A lifting frame is fixedly installed on the output end of the opening and closing electric cylinder. An upper template is fixedly installed on the lifting frame. Two outer push plates are slidably installed on the upper template. A slope is provided on the upper surface of the outer push plates. A horizontal spring is provided between the outer push plates and the upper template. An entry hole is provided on the upper template. In the initial state, the outer push plates close the entry hole.

[0008] Furthermore, the forming mechanism also includes a positioning slide plate and an insertion plate that are slidably mounted on the main frame. The positioning slide plate is provided with five limiting grooves, and the insertion plate is provided with five through holes. The positions of the through holes and the limiting grooves are consistent. A return spring is provided between the insertion plate and the main frame, and a return spring is also provided between the positioning slide plate and the main frame. Two outer top slope blocks and multiple steel bar holes are fixedly installed on both the positioning slide plate and the insertion plate. The lower surface of the outer top slope block is provided with a slope.

[0009] Furthermore, the molding mechanism also includes an opening and closing frame that is slidably mounted on the main frame. An opening and closing spring is provided between the opening and closing frame and the main frame. A feed pipe is fixedly mounted on the main frame. The outlet end of the feed pipe is located above the inlet hole. An opening and closing shell is fixedly mounted on the feed pipe. An opening and closing plate is fixedly mounted on the opening and closing frame. The opening and closing plate slides inside the opening and closing shell.

[0010] Furthermore, the upper template, positioning slide, insertion plate, and two side bottom templates form an internally enclosed space.

[0011] In use, remove the plugs from the insertion holes and insert five steel bars into the five insertion holes. Then, insert the five steel bars into the limiting grooves, ensuring the top of each bar reaches the groove and the tail end is positioned within the insertion hole without protruding beyond it. Next, insert the plugs used to seal the insertion holes, thus closing them. Then, the electric cylinder retracts, causing the lifting frame and upper template to rise. When the slope of the outer push plate contacts the bottom of the feed pipe, the feed pipe pushes the two outer push plates outwards, compressing the horizontal spring and inserting the feed pipe into the entry hole. The outer push plates then continue to rise, pushing the opening and closing frame. As the plate rises, the opening and closing spring is stretched, and the opening and closing plate no longer closes the feed pipe. External concrete enters from the feed pipe between the side bottom template, positioning slide plate, and insertion plate. When the mold is full of concrete, the opening and closing electric cylinder extends, driving the upper template and outer push plate to descend. When the outer push plate disengages from the lower end of the opening and closing frame, the opening and closing spring rebounds, driving the opening and closing frame and opening and closing plate to descend. The opening and closing plate closes the feed pipe again. Subsequently, when the outer push plate disengages from the bottom of the feed pipe, the horizontal spring rebounds, causing the outer push plate to reach above the inlet hole again, closing the inlet hole. At this time, the upper template, positioning slide plate, insertion plate, and two side bottom templates enclose the concrete inside.

[0012] During the concrete setting process, the electric cylinder can retract slightly, causing the upper formwork to rise. At this time, air bubbles at the top of the concrete can be expelled, and the outer push plate will not come into contact with the feed pipe.

[0013] Furthermore, the coating mechanism also includes a movable frame fixedly installed on the main frame, a sliding groove is provided in the movable frame, a compression spring is provided between the horizontal sliding column and the movable frame, guide columns are provided on both sides of the movable frame, the guide columns on both sides of the movable frame slide and rotate in the movable frame, a movable gear is fixedly installed on the guide column of the movable frame, and a fixed rack is fixedly installed on the main frame. When the side bottom template moves outward and disengages from the horizontal sliding column, the movable gear and the fixed rack begin to mesh.

[0014] Furthermore, the coating mechanism also includes two brushing motors fixedly installed on both sides of the main frame, and two brushing soft wheels rotatably installed on the main frame. The brushing soft wheels are fixedly installed with the motor shafts of the brushing motors, and the brushing soft wheels are coated with release agent.

[0015] When the movable frame moves outward, it drives the side bottom template to move outward as well. At this time, the lower limit plate supports the side bottom template, so the movable frame cannot rotate freely. After the side bottom template leaves the lower limit plate, the movable gear begins to mesh with the fixed rack. As the movable frame moves outward, the fixed rack drives the movable gear and the movable frame to rotate 180 degrees, so that the side bottom template is upside down on the brushing wheel. The brushing motor drives the brushing wheel to rotate, and the brushing wheel brushes the release agent onto the side bottom template.

[0016] When the movable frame moves inward, under the action of the fixed rack, it drives the side bottom templates, which have been coated with release agent, to rotate 180 degrees and fall back to the lower limit plate. Then the movable frame continues to move inward, so that the two side bottom templates fit together. After the two side bottom templates fit together, the movable frame will continue to move a short distance, so that the horizontal sliding column slides relative to the movable frame, and the compression spring is compressed a short distance, so that the lower surfaces of the two side bottom templates fit tightly together.

[0017] Furthermore, the extraction mechanism includes two bottom electric cylinders located below the main frame. A bottom connecting rod is rotatably mounted on the output end of the bottom electric cylinder, a lower lifting frame is rotatably mounted on the bottom connecting rod, and an outer push rod is rotatably mounted on the lower lifting frame. The outer push rod is rotatably mounted to the movable frame.

[0018] Furthermore, the extraction mechanism also includes a material support plate rotatably mounted on the lower lifting frame. The material support plate is provided with multiple lower top ramps, and the lower top ramps are provided with slopes. A lower rotating block is rotatably mounted below the material support plate, and an inclined spring is provided between the lower rotating block and the lower lifting frame.

[0019] After molding is completed, the bottom electric cylinder extends, driving the lower lifting frame to rise via the bottom connecting rod. The lower lifting frame then drives the material support plate to rise. Simultaneously, the lower lifting frame drives the movable frame and side bottom template to move outward via the outer push rod. Since the two ends of the reinforcing bars are still in the insertion holes and limiting grooves, the precast concrete component will not fall off at this time. When the slope surface of the top slope block contacts the slope surface of the outer slope block, it pushes the insertion plate and positioning slide plate to slide outward. The return spring is compressed, and the precast concrete component falls onto the material support plate. Then, the bottom electric cylinder retracts, driving the lower lifting frame and material support plate to descend. The lower lifting frame drives the movable frame and side bottom template to move inward via the outer push rod. When the top slope block separates from the outer slope block, the return spring rebounds, causing the positioning slide plate and insertion plate to return to their initial positions. Then, the material support plate descends with the precast component. By pressing down one end of the material support plate, the material support plate can rotate relative to the lower lifting frame, facilitating the sliding out of the precast concrete component.

[0020] The beneficial effects of this invention compared with the prior art are: (1) The coating mechanism set in this invention automatically flips the side bottom template and attaches it to the rotating brushing soft wheel during the demolding process, and completes the uniform and quantitative coating of the release agent, replacing the inefficient and unstable manual brushing, which not only improves efficiency and ensures the surface smoothness of the component, but also reduces the waste of release agent, making it more energy-saving and environmentally friendly; (2) The removal mechanism set in this invention completes the opening of the side template, the lifting and demolding of the component and the receiving and falling of the finished product simultaneously through the single drive of the bottom electric cylinder, and the whole process does not require manual intervention; (3) This invention realizes the injection of concrete into a completely closed mold, which effectively prevents grout leakage. At the same time, the unique controllable venting function allows the upper template to be slightly raised in the early stage of solidification to release air bubbles, thereby reducing defects such as air holes and pitting on the surface of the component, and improving the internal density and appearance quality consistency of the component.

Detailed Implementation

[0030] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0031] Example: Reference Figures 1-8An energy-saving lightweight precast concrete component forming equipment includes a forming mechanism for casting precast concrete components. The forming mechanism includes a main frame 101 and is equipped with a coating mechanism for applying a release agent and a take-out mechanism for removing the formed precast concrete components. The coating mechanism includes a lower limit plate 202 fixedly installed on the main frame 101. Two side bottom templates 201 are slidably installed on the lower limit plate 202. The lower surfaces of the two side bottom templates 201 are in contact. A horizontal sliding column 203 is fixedly installed on the side bottom template 201. A movable frame 204 is slidably installed on the horizontal sliding column 203.

[0032] like Figures 2-4 As shown, the molding mechanism includes an opening and closing electric cylinder 104 fixedly installed on the main frame 101. A lifting frame 112 is fixedly installed on the output end of the opening and closing electric cylinder 104. An upper template 109 is fixedly installed on the lifting frame 112. Two outer push plates 113 are slidably installed on the upper template 109. The upper surface of the outer push plate 113 is provided with a slope. A horizontal spring 114 is provided between the outer push plate 113 and the upper template 109. An entry hole 115 is provided on the upper template 109. In the initial state, the outer push plate 113 closes the entry hole 115.

[0033] like Figures 2-4 As shown, the forming mechanism also includes a positioning slide plate 102 and an insertion plate 110 slidably mounted on the main frame 101. The positioning slide plate 102 is provided with five limiting grooves 119, and the insertion plate 110 is provided with five through holes 118. The positions of the through holes 118 and the limiting grooves 119 are consistent. A return spring 111 is provided between the insertion plate 110 and the main frame 101, and a return spring 111 is also provided between the positioning slide plate 102 and the main frame 101. Two outer top slope blocks 116 and multiple steel bar holes 117 are fixedly installed on both the positioning slide plate 102 and the insertion plate 110. The lower surface of the outer top slope block 116 is provided with a slope.

[0034] like Figures 2-4 As shown, the molding mechanism also includes an opening and closing frame 105 slidably mounted on the main frame 101. An opening and closing spring 106 is provided between the opening and closing frame 105 and the main frame 101. A feed pipe 103 is fixedly mounted on the main frame 101. The outlet end of the feed pipe 103 is located above the inlet hole 115. An opening and closing shell 107 is fixedly mounted on the feed pipe 103. An opening and closing plate 108 is fixedly mounted on the opening and closing frame 105. The opening and closing plate 108 slides inside the opening and closing shell 107.

[0035] like Figures 2-4 As shown, the upper template 109, positioning slide plate 102, insertion plate 110 and two side bottom templates 201 form an internally enclosed space.

[0036] In use, remove the plugs from the insertion holes 118, insert five steel bars into the five insertion holes 118, and then insert the five steel bars into the limiting grooves 119, with the top of the steel bars touching the limiting grooves 119. The tail of the steel bars is now located in the insertion hole 118 and does not extend beyond the outside of the insertion hole 118. Then, insert the plugs used to seal the insertion holes 118, thus sealing the insertion holes 118. Subsequently, the opening and closing electric cylinder 104 retracts, driving the lifting frame 112 and the upper template 109 to rise. When the slope of the outer push plate 113 contacts the bottom of the feed pipe 103, the feed pipe 103 pushes the two outer push plates 113 outward, compressing the horizontal spring 114, causing the feed pipe 103 to insert into the entry hole 115. Then, the outer push plate 113 continues to rise, pushing the opening and closing frame 105 and the opening and closing plate 108 to rise, opening and closing. When spring 106 is stretched, opening and closing plate 108 no longer closes the feed pipe 103. External concrete enters from the feed pipe 103 into the space between the side bottom template 201, positioning slide plate 102, and insertion plate 110. When the mold is full of concrete, opening and closing electric cylinder 104 extends, driving the upper template 109 and outer push plate 113 to descend. When the outer push plate 113 disengages from the lower end of the opening and closing frame 105, opening and closing spring 106 rebounds, driving the opening and closing frame 105 and opening and closing plate 108 to descend. Opening and closing plate 108 closes the feed pipe 103 again. Subsequently, when the outer push plate 113 disengages from the bottom of the feed pipe 103, horizontal spring 114 rebounds, causing the outer push plate 113 to reach above the inlet hole 115 again, closing the inlet hole 115. At this time, the upper template 109, positioning slide plate 102, insertion plate 110, and two side bottom templates 201 enclose the concrete within.

[0037] During the concrete solidification process, the opening and closing electric cylinder 104 can retract slightly, driving the upper formwork 109 to rise. At this time, air bubbles at the top of the concrete can be discharged, and the outer push plate 113 will not come into contact with the feed pipe 103.

[0038] like Figure 5 , Figure 6 As shown, the coating mechanism also includes a movable frame 206 fixedly installed on the main frame 101. A sliding groove is provided in the movable frame 206. A compression spring 205 is provided between the horizontal sliding column 203 and the movable frame 204. Guide columns are provided on both sides of the movable frame 204. The guide columns on both sides of the movable frame 204 slide and rotate in the movable frame 206. Movable gears 207 are fixedly installed on the guide columns of the movable frame 204. A fixed rack 208 is fixedly installed on the main frame 101. When the side bottom template 201 moves outward and disengages from the horizontal sliding column 203, the movable gear 207 and the fixed rack 208 begin to mesh.

[0039] like Figure 5 , Figure 6As shown, the coating mechanism also includes two brushing motors 209 fixedly installed on both sides of the main frame 101. Two brushing soft wheels 210 are rotatably installed on the main frame 101. The brushing soft wheels 210 are fixedly installed with the motor shafts of the brushing motors 209. The brushing soft wheels 210 are coated with release agent.

[0040] When the movable frame 204 moves outward, it drives the side bottom template 201 to move outward as well. At this time, the lower limit plate 202 supports the side bottom template 201, so the movable frame 204 cannot rotate freely. After the side bottom template 201 leaves the lower limit plate 202, the movable gear 207 begins to mesh with the fixed rack 208. As the movable frame 204 moves outward, the fixed rack 208 drives the movable gear 207 and the movable frame 204 to rotate 180 degrees, so that the side bottom template 201 is upside down on the brushing soft wheel 210. The brushing motor 209 drives the brushing soft wheel 210 to rotate, and the brushing soft wheel 210 brushes the release agent onto the side bottom template 201.

[0041] When the movable frame 204 moves inward, under the action of the fixed rack 208, the side bottom template 201, which has been coated with release agent, rotates 180 degrees and falls back onto the lower limit plate 202. Then the movable frame 204 continues to move inward, so that the two side bottom templates 201 fit together. After the two side bottom templates 201 fit together, the movable frame 204 will continue to move a short distance, so that the horizontal sliding column 203 slides relative to the movable frame 204, and the compression spring 205 is compressed a short distance, so that the lower surfaces of the two side bottom templates 201 fit tightly together.

[0042] like Figure 7 , Figure 8 As shown, the removal mechanism includes two bottom electric cylinders 301 located below the main frame 101. A bottom connecting rod 302 is rotatably mounted on the output end of the bottom electric cylinder 301. A lower lifting frame 303 is rotatably mounted on the bottom connecting rod 302. An outer push rod 308 is rotatably mounted on the lower lifting frame 303. The outer push rod 308 is rotatably mounted with the movable frame 204.

[0043] like Figure 7 , Figure 8 As shown, the extraction mechanism also includes a material support plate 304 rotatably mounted on the lower lifting frame 303. The material support plate 304 is provided with a plurality of lower top ramps 305, and the lower top ramps 305 are provided with a slope. A lower rotating block 306 is rotatably mounted below the material support plate 304, and an inclined spring 307 is provided between the lower rotating block 306 and the lower lifting frame 303.

[0044] After molding is completed, the bottom electric cylinder 301 extends, driving the lower lifting frame 303 to rise via the bottom connecting rod 302. The lower lifting frame 303 drives the material support plate 304 to rise. At the same time, the lower lifting frame 303 drives the movable frame 204 and the side bottom template 201 to move outward via the outer push rod 308. Since the two ends of the reinforcing bars are still located in the insertion hole 118 and the limiting groove 119, the precast concrete component will not fall off at this time. After the slope surface of the top slope block 305 contacts the slope surface of the outer slope block 116, it pushes the insertion plate 110 and the positioning slide plate 102 to slide outward. The return spring 111 is compressed, and the precast concrete component moves outward with the concrete. The component falls onto the support plate 304, and then the bottom electric cylinder 301 retracts, driving the lower lifting frame 303 and the support plate 304 to descend. The lower lifting frame 303 drives the movable frame 204 and the side bottom template 201 to move inward through the outer push rod 308. After the lower top slope block 305 disengages from the outer top slope block 116, the return spring 111 rebounds, causing the positioning slide plate 102 and the insertion plate 110 to return to their initial positions. Then the support plate 304 descends with the precast component. By pressing down one end of the support plate 304, the support plate 304 can rotate relative to the lower lifting frame 303, which facilitates the sliding out of the precast concrete component.

[0045] The working principle of the energy-saving lightweight precast concrete component molding equipment disclosed in this invention is as follows: During use, the plugs on the insertion holes 118 are removed, and five reinforcing bars are inserted through the five insertion holes 118. The five reinforcing bars are then inserted into the limiting grooves 119, with the top ends of the reinforcing bars touching the limiting grooves 119. The tail ends of the reinforcing bars are then positioned within the insertion holes 118 and do not extend beyond the outside of the insertion holes 118. The plugs used to seal the insertion holes 118 are then inserted, sealing the insertion holes 118. Subsequently, the opening and closing electric cylinder 104 retracts, driving the lifting frame 112 and the upper template 109 to rise. When the slope of the outer push plate 113 contacts the bottom of the feed pipe 103, the feed pipe 103 pushes the two outer push plates 113 outwards, compressing the horizontal spring 114, causing the feed pipe 103 to insert into the entry hole 115. The outer push plates 113 then continue to rise, pushing the opening and closing mechanism. As the frame 105 and opening / closing plate 108 rise, the opening / closing spring 106 is stretched, and the opening / closing plate 108 no longer closes the feed pipe 103. External concrete enters from the feed pipe 103 into the space between the side bottom template 201, the positioning slide plate 102, and the insertion plate 110. When the mold is full of concrete, the opening / closing electric cylinder 104 extends, driving the upper template 109 and the outer push plate 113 to descend. When the outer push plate 113 disengages from the lower end of the opening / closing frame 105, the opening / closing spring 106 rebounds, driving the opening / closing frame 105 and the opening / closing plate 108 to descend. The opening / closing plate 108 closes the feed pipe 103 again. Subsequently, when the outer push plate 113 disengages from the bottom of the feed pipe 103, the horizontal spring 114 rebounds, causing the outer push plate 113 to reach above the inlet hole 115 again, closing the inlet hole 115. At this time, the upper template 109, the positioning slide plate 102, the insertion plate 110, and the two side bottom templates 201 enclose the concrete within. During the concrete solidification process, the opening and closing electric cylinder 104 can retract slightly, driving the upper formwork 109 to rise. At this time, air bubbles at the top of the concrete can be discharged, and the outer push plate 113 will not come into contact with the feed pipe 103.

[0046] After molding is completed, the bottom electric cylinder 301 extends, driving the lower lifting frame 303 to rise via the bottom connecting rod 302. The lower lifting frame 303 then drives the material support plate 304 to rise. Simultaneously, the lower lifting frame 303 drives the movable frame 204 and the side bottom template 201 to move outward via the outer push rod 308. When the movable frame 204 moves outward, it also drives the side bottom template 201 to move outward together. At this time, the lower limit plate 202 supports the side bottom template 201, and the movable frame 204... Unable to rotate freely, after the side bottom template 201 leaves the lower limit plate 202, the movable gear 207 begins to mesh with the fixed rack 208. As the movable frame 204 moves outward, the fixed rack 208 drives the movable gear 207 and the movable frame 204 to rotate 180 degrees, causing the side bottom template 201 to be upside down on the brushing soft wheel 210. The brushing motor 209 drives the brushing soft wheel 210 to rotate, and the brushing soft wheel 210 brushes the release agent onto the side bottom template 201. Since both ends of the reinforcing bar are still located in the insertion hole 118 and the limiting groove 119, the precast concrete component will not fall off at this time. After the slope surface of the lower top slope block 305 contacts the slope surface of the outer top slope block 116, it pushes the insertion plate 110 and the positioning slide plate 102 to slide outward, the return spring 111 is compressed, and the precast concrete component falls onto the support plate 304. Then the bottom electric cylinder 301 retracts, driving the lower lifting frame 303 and the support plate 304 to descend. The lower lifting frame 303 drives the movable frame 204 and the side bottom template 201 through the outer push rod 308. Moving inward, when the movable frame 204 moves inward, under the action of the fixed rack 208, it drives the side bottom template 201, which has been coated with release agent, to rotate 180 degrees and fall back onto the lower limit plate 202. Then, the movable frame 204 continues to move inward, causing the two side bottom templates 201 to fit together. After the two side bottom templates 201 fit together, the movable frame 204 will continue to move a short distance, causing the horizontal sliding column 203 to slide relative to the movable frame 204. The compression spring 205 is compressed a short distance, and the lower surfaces of the two side bottom templates 201 fit tightly together. When the lower top slope block 305 separates from the outer top slope block 116, the return spring 111 rebounds, causing the positioning slide plate 102 and the insertion plate 110 to return to their initial positions. Then, the material support plate 304 descends with the precast component. By pressing down one end of the material support plate 304, the material support plate 304 can rotate relative to the lower lifting frame 303, facilitating the sliding out of the precast concrete component.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
