Description

Technical Field

[0001] This utility model relates to the field of foaming and demolding of insulation boards, and in particular to a foam particle insulation board foaming molding, automatic demolding mold box and limiting structure. Background Technology

[0002] Foam particle insulation board, a building insulation material made primarily of polystyrene resin, is widely used in building wall and roof insulation due to its lightweight and excellent thermal insulation properties. The manufacturing process typically involves mixing foam particles (polystyrene particles), foaming agents, and flame retardants to form a slurry, which is then added to a mold for foaming and molding into solid granular blocks.

[0003] The lack of an effective compression control mechanism during foaming of the slurry in the mold box leads to excessive expansion of the slurry within the mold box, resulting in insufficient density of the foam particles after molding, which affects the mechanical properties and insulation effect of the insulation board. In addition, existing mold boxes rely heavily on manual demolding after foaming and molding, requiring manual removal of the box from the solid particles after molding. The manual demolding method has a low degree of automation, increases the labor intensity of workers, and also limits the improvement of production efficiency. Utility Model Content

[0004] To overcome the problems of insufficient density of the slurry after foaming in the mold box and high labor intensity of manual demolding in the above-mentioned background technology, this utility model provides a foam particle insulation board foaming molding, automatic demolding mold box and limiting structure. By setting the limiting structure to limit the height of the cover plate, the foaming density of the slurry is controlled by compression. The demolding equipment can automatically remove the solid particle blocks after foaming and molding from the mold box. It has the beneficial effects of increasing the density of the solid particle blocks, making the molded solid particle blocks more compact, improving the molding quality, high degree of automation, significantly reducing the labor intensity of manual labor, and improving production efficiency.

[0005] The technical solution of this utility model is as follows:

[0006] A foam particle insulation board foaming molding and automatic demolding mold box includes a mold box, slurry is injected into the mold box and foamed, and also includes a demolding device and a cover plate that is placed in the mold box after slurry injection and pressed on the surface of the slurry. The cover plate can allow the slurry in the mold box to reach a set height; the demolding device removes the solid particle blocks after foaming from the mold box.

[0007] Preferably, the mold box includes a side panel and a bottom plate, with the side panel placed vertically on the surface of the bottom plate and engaging with it.

[0008] More preferably, the base plate has upwardly protruding limiting blocks on both sides, and the surrounding plate is engaged between the limiting blocks on both sides when it is assembled with the base plate.

[0009] More preferably, the inner side of the limiting block has a sloping structure and is inclined inward from top to bottom; the bottom plate is also fixed with a latch lock, and the latch lock's locking ring can be embedded in the corresponding slot on the surrounding plate.

[0010] More preferably, the demolding device includes a pressure plate and a lifting frame. During demolding, the pressure plate presses down on the cover plate, and the lifting frame lifts the surrounding plate upward through the support plates on both sides of the mold box to separate it from the foam particle block.

[0011] In a further preferred embodiment, the demolding device also includes a hydraulic mechanism that provides power. During demolding, the hydraulic mechanism controls the pressure plate to press against the cover plate and the lifting frame to move upward.

[0012] More preferably, the demolding device further includes a cylinder that can push the foam particle block forward on the slide, wherein the height of the top surface of the slide is less than or equal to the height of the top surface of the base plate.

[0013] This application also provides a limiting structure for the above-mentioned mold box, including a limiting plate that can pass through the enclosure and limit the rising height of the cover plate.

[0014] In a further preferred embodiment, the limiting structure is arranged on the outside of the mold box's surrounding plate, and the surrounding plate has a limiting hole. The limiting plate passes through the limiting hole and can rotate up and down within the limiting hole, entering or leaving the mold box. Its lower part can be pressed against the surrounding plate under the action of a torsion spring, limiting the upward rotation range of the surrounding plate.

[0015] More preferably, the limiting structure is arranged along the circumference of the mold box, and 2-3 sets of limiting structures are provided on each side of the enclosure.

[0016] Compared with existing technologies, the advantages of the above technical solution are as follows:

[0017] By using the cooperation of various components in the demolding equipment, the solid granules after foaming are automatically separated from the surrounding plate, cover plate and top plate, realizing automated demolding, greatly reducing the intensity of manual labor, improving the degree of automation and improving production efficiency. By connecting and cooperating the limiting plate and limiting hole in the limiting structure, the cover plate can be restricted to a fixed height in the mold box, so that the slurry can only reach the set height, realizing compression control, improving the foaming density of the slurry, increasing the density after foaming and molding, making the solid granules more compact, improving the molding quality, and the cover plate covering the surface of the slurry also improves the smoothness of the surface of the solid granules after molding.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Example 1: As Figures 1 to 5 The diagram shows a foam particle insulation board foaming molding and automatic demolding mold box, including a mold box 1, into which slurry is injected and foamed, and also includes a demolding device and a cover plate 11 that is placed in the mold box 1 after the slurry is injected and pressed against the surface of the slurry. The cover plate 11 can make the slurry in the mold box 1 reach a set height, and the foaming density of the slurry is controlled by compression; the demolding device removes the solid particle blocks after the slurry foaming is formed from the mold box 1.

[0029] After the slurry is injected into the mold box 1 and allowed to stand, the cover plate 11 can be fixed at a fixed height inside the mold box 1. At this time, the slurry reaches the set height, and compression control is achieved to increase the slurry density, increase the density after foaming, and make the solid granules after molding more compact, thus improving the molding quality. Covering the surface of the slurry with the cover plate 11 also improves the smoothness of the surface of the solid granules after molding. By using a demolding device to automatically remove the foamed solid granules from the mold box 1, the intensity of manual labor can be greatly reduced, the degree of automation can be improved, and the production efficiency can be increased.

[0030] Example 2: Based on Example 1, the structure of the mold box 1 is optimized. The mold box 1 includes a surrounding plate 12 and a bottom plate 13. The surrounding plate 12 is placed vertically on the surface of the bottom plate 13 and is connected to it. The surrounding plate 12 is a rectangular structure that is open at the top and bottom and is connected to the bottom plate 13. The two are detachably and fixedly connected.

[0031] Specifically, the base plate 13 has upwardly protruding limiting blocks 31 on both sides. When the surrounding plate 12 is assembled with the base plate 13, it is snapped between the limiting blocks 31 on both sides. The inner side of the limiting block 31 is a sloping structure and is inclined inward from top to bottom. By setting the limiting block 31 with this structure, it is easier for the surrounding plate 12 to move downward along the inner side of the limiting block 31, be placed on the base plate 13 and snapped and fixed between the limiting blocks 31 on both sides. This structure will not affect the separation of the surrounding plate 12 and the base plate 13 during demolding. Two limiting blocks 31 can be set on each of the opposite sides of the base plate 13.

[0032] Preferably, a latch lock 32 is also fixed to the periphery of the base plate 13. The locking ring 321 of the latch lock 32 can be embedded into the corresponding slot 33 on the surrounding plate 12. The latch lock 32 is a mechanical device that achieves the locking function by engaging the locking ring 321. In this embodiment, there are four latch locks 32, which are respectively arranged on the four corners of the base plate 13. Corresponding slots 33 are provided at the corresponding positions on the surrounding plate 12. Before injecting slurry into the mold box 1, the locking ring 321 is rotated upward and fastened into the corresponding slot 33. Before demolding, the locking ring 321 is rotated out of the slot 33.

[0033] Example 3: Based on Example 1, the demolding equipment is optimized. The demolding equipment includes a pressure plate 21 and a lifting frame 22. The pressure plate 21 can press down the cover plate 11. There are two sets of lifting frames 22, which stand opposite each other. The lifting frame 22 has a frame structure, and its bottom is a horizontally arranged lifting plate 221. The pressure plate 21 is arranged between the two sets of lifting frames 22. The top of the surrounding plate 12 of the mold box 1 has outwardly protruding support plates 14 on opposite sides. The distance between the two sets of lifting frames 22 and the lifting plates 221 is based on the width of the mold box 1 and the support plates 14, which must allow the mold box 1 to be placed between the two sets of lifting frames 22, and the lifting plates 221 can also be placed directly below the corresponding support plates 14.

[0034] When the mold box 1 needs to be demolded, the mold box 1 is slid between the two sets of lifting frames 22. The lifting plate 221 is then engaged under the support plates 14 on both sides of the mold box 1. When the lifting frame 22 moves upward, the pressure plate 21 presses down on the cover plate 11, and the lifting plate 221 can lift the surrounding plate 12 upward through the support plate 14 to separate it from the foam granule block.

[0035] The demolding equipment is powered by a hydraulic mechanism 40. One hydraulic cylinder in the hydraulic mechanism 40 controls the pressure plate 21 to press down the cover plate 11, while the other hydraulic cylinder simultaneously controls the lifting frame 22 to move upward. Thus, during demolding, the pressure plate 21 presses down the cover plate 11, and the lifting frame 22 can lift the enclosure plate 12, causing the foam granule blocks to detach from the enclosure plate 12.

[0036] Example 4: Based on the above examples, a preferred design is made. The demolding device further includes a cylinder 41 that can push the foam granule blocks forward on the slide 51. Both the cylinder 41 and the slide 51 are arranged on the ground foundation 5. The height of the top surface of the slide 51 is less than or equal to the height of the top surface of the base plate 13, that is, the top surface of the slide 51 is lower than or flush with the top surface of the base plate 13. In this example, the slide 51 is flush with the base plate 13 of the mold box 1, and the base plate 13 can be placed in the groove 52 of the ground foundation 5. This arrangement makes it easier for the base plate 13 to separate from the foam granule blocks and slide onto the slide 51. After the foam granules are moved onto the slide 51, the cover plate 11 can be lifted by a suction device or manually. If a suction device is used, a magnetic suction plate 42 (such as a magnet) can be set on the bottom surface of the lifting rod 401 of the hydraulic mechanism 40, and the cover plate 11 can be made of ferromagnetic material. The cover plate 11 can be lifted by the magnetic suction plate 42 and lifted upward by the lifting rod 401 to move it away from the foam granules, thus completing the separation of the cover plate 11 from the foam granules.

[0037] After the enclosure plate 12 of the mold box 1 is separated from the foam granule block, the control cylinder 41 is activated. The moving end of the piston rod 411 of the cylinder 41 is fixed with the push plate 412. When the piston rod 411 extends, the push plate 412 pushes forward and presses against the lower part of the foam granule block, which can push the foam granule block towards the slide 51. Since the adhesion between the cover plate 11 and the foam granule block is less than the weight of the foam granule block itself, the magnetic suction plate 42 can easily pick up the cover plate 11 and separate it from the foam granule block, thus completing the final demolding work.

[0038] Example 5: Based on Example 1, this example also provides a limiting structure for the above-mentioned mold box 1, including a limiting plate 61, which can pass through the surrounding plate 12 and limit the rising height of the cover plate 11.

[0039] Specifically, the limiting structure 6 is installed inside the limiting frame 62 fixed to the outside of the surrounding plate 12 of the mold box 1. The limiting plate 61 can be a triangular plate, which is sleeved on the limiting post 63 and perpendicularly connected to it. The limiting post 63 passes through both sides of the limiting frame 62 and is parallel to the corresponding mounting surface of the surrounding plate 12. The surrounding plate 12 of the mold box 1 has a limiting hole 64. The limiting plate 61 passes through the limiting hole 64 and can rotate up and down within the limiting hole 64, entering or leaving the mold box 1. Its lower part can be pressed against the surrounding plate 12 under the action of the torsion spring 65, limiting the upward rotation range of the limiting plate 61 within the limiting hole 64. The torsion spring 65 is wound around the limiting post 63 and extends to the lower part of the limiting plate 61.

[0040] When the cover plate 11 needs to be placed inside the mold box 1, the cover plate 11 moves down along the inner side of the surrounding plate 12. When it reaches the position of the limiting structure 6, the limiting plate 61 is pressed down, causing the limiting plate 61 to rotate along the limiting post 63 and move away from the inner side of the mold box 1. After the cover plate 11 moves downward away from the position of the limiting structure 6, the torsion spring 65 controls the limiting plate 61 to rotate in the opposite direction to reset and abut against the outer side of the surrounding plate 12. Therefore, the limiting plate 61 can be restricted from continuing to rotate upward in the limiting hole 64, preventing the cover plate 11 from moving upward, which would result in insufficient density of the foam particles after foaming and molding, affecting the mechanical properties and insulation effect of the insulation board.

[0041] Preferably, the limiting structure 6 is arranged around the circumference of the mold box 1, and 2-3 sets of limiting structures 6 are provided on each side of the enclosure 12 to improve the limiting effect on the cover plate 11.

[0042] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the technical solution of this application, and these all fall within the scope of protection of this application.
