Description

TECHNICAL FIELD

[0002] The thermal insulation wallboard is mainly composed of thermal insulation materials and panels, wherein the thermal insulation materials mainly include polystyrene, mineral wool, silicate and the like, and these materials have the advantages of light weight, environmental protection and the like. The panels mainly include cement fiber boards, aluminum plates and the like, and these materials have good pressure resistance. The existing extrusion process usually pours mixed materials into a mold cavity, uses a pressurizing device to extrude and shape the mixed materials, and demolds the shaped materials after shaping. The shaped materials after demolding are cut and adjusted by workers to make the outer surface of the shaped materials more flat, and the shaped materials after cutting and adjusting are adhered to the panels to form wallboards. However, the existing demolding method is very complex and it is not easy to take out the panels.

[0003] The patent with the publication number CN217257043U discloses an extrusion forming equipment for partition wallboard, which is provided with an extrusion push rod, an extrusion plate, telescopic hydraulic rods, a forming mold and the like. When the shaped wallboard needs to be taken out, the worker drives the extrusion plate to rise by the extrusion push rod, adjusts the extension size of the telescopic shafts of the two telescopic hydraulic rods after the extrusion plate rises to a suitable position, and thereby lifts the forming mold to a vertical state. Then, the wallboard in the forming mold in the vertical state is inclined to one side by the inclined setting of the inner cavity bottom of the forming mold, thereby achieving the effect of easier demolding.

[0004] However, the mixed materials are easy to adhere to the inner cavity inner wall of the forming mold during the extrusion forming process, and only the inclined setting of the inner cavity of the forming mold cannot achieve a good auxiliary demolding effect after the adhesion of the mixed materials and the inner cavity inner wall. The worker needs to manually demold, and the shaped wallboard is located in the inner cavity of the forming mold, so it is difficult for the worker to demold, which is not conducive to the taking out of the shaped wallboard, and the demolding has certain limitations.

[0027] The guide plate 17 can limit and guide the top plate 15, so that the top plate 15 is more stable when sliding up and down. The disc 22 can limit the top plate 15, so as to avoid the disengagement of the top plate 15 and the guide plate 17.

[0028] A plurality of protrusions 21 are fixedly arranged on the top of the top plate 15, a plurality of clearance holes are formed on the bottom of the die cavity of the forming die 16, the number of the protrusions 21 and the clearance holes is equal and one-to-one sliding sealing cooperation. The protrusions 21 can be made of high-hardness materials such as silicon carbide and stainless steel for sealing.

[0029] The pressing plate 4 is in transmission cooperation with the top plate 15. One tooth plate 5 is fixedly arranged at the left and right sides of the pressing plate 4, both tooth plates 5 are L-shaped, the forming die 16 is located between the two tooth plates 5, and the smooth pressing of the pressing plate 4 is ensured.

[0030] Two fixed plates 6 are fixedly arranged vertically on the top of the bottom plate 1, and the two fixed plates 6 are arranged on the left and right sides of the forming die 16. A connecting rod 7 is rotatably arranged on the opposite side of the two fixed plates 6, and a second pulley 11 is rotatably arranged on the connecting rod 7. A gear 9 and a first pulley 8 are coaxially fixedly arranged on the outer surface of the connecting rod 7, and a clamping rod 12 is fixedly and horizontally eccentrically arranged on the opposite side of the second pulley 11.

[0031] The toothed plate 5 and the gear 9 are equal in number and one-to-one correspondence, each toothed plate 5 is engaged with the corresponding gear 9. The first pulley 8 and the second pulley 11 are equal in number and one-to-one correspondence, each first pulley 8 is transmission sleeved with the corresponding second pulley 11. The waist type slot guide rail 13 and the clamping rod 12 are equal in number and one-to-one correspondence, each clamping rod 12 is limited to slide in the corresponding waist type slot guide rail 13.

[0032] Through the engagement of the toothed plate 5 and the gear 9, the first pulley 8 is driven to rotate by the cylinder 3, and the first pulley 8 drives the second pulley 11 to rotate through the belt 10. The second pulley 11 drives the clamping rod 12 to rotate, and the clamping rod 12 drives the top plate 15 to slide up and down under the limitation of the guide plate 17, thereby performing demolding.

[0033] The drawings in the specification are structural schematic diagrams, and the specific size can be adjusted according to actual use.

[0034] The working principle of the first embodiment is as follows: when the mixture needs to be extruded, the cylinder 3 is started, and the extension shaft of the cylinder 3 is controlled to be elongated. The extension shaft of the cylinder 3 drives the pressing plate 4 to move downward, and the pressing plate 4 drives the toothed plate 5 to move synchronously in the process of moving downward, and the toothed plate 5 drives the gear 9 to rotate, and the gear 9 drives the first pulley 8 to rotate through the connecting rod 7. The first pulley 8 drives the second pulley 11 to rotate through the belt 10, and the second pulley 11 drives the clamping rod 12 to rotate around the center axis of the second pulley 11 through the rotating shaft.

[0035] Subsequently, under the limited sliding cooperation of the clamping rod 12 and the waist type slot guide rail 13 and the limitation of the guide plate 17, the clamping rod 12 rotates and drives the waist type slot guide rail 13 to move downward. The waist type slot guide rail 13 moves and drives the top plate 15 to move downward through the connecting plate 14, and the top plate 15 moves downward and drives the protrusion 21 to move downward in the clearance hole.

[0036] When the toothed plate 5 and the gear 9 are completely disengaged, the top of the protrusion 21 is just flush with the bottom of the mold cavity, and the protrusion 21 completely seals all the clearance holes. At this time, the bottom of the top plate 15 just touches the top of the disc 22, thereby limiting the top plate 15, avoiding the sliding of the protrusion 21 in the process of extrusion.

[0037] Subsequently, the cylinder 3 is closed, and the mixture is placed in the forming mold 16. After the mixture is placed, the cylinder 3 is started, and the extension shaft of the cylinder 3 is controlled to be elongated. The extension shaft of the cylinder 3 drives the pressing plate 4 to move downward, thereby gradually inserting into the mold cavity and extruding the mixture in the mold cavity, so that the mixture is gradually extruded into a wallboard shape.

[0038] When the formed wallboard needs to be taken out, the telescopic shaft of the air cylinder 3 is controlled to contract. The contraction of the telescopic shaft of the air cylinder 3 drives the pressing plate 4 to move upwards, and the upward movement of the pressing plate 4 gradually separates from the mold cavity. With the continuous upward movement of the pressing plate 4, the pressing plate 4 drives the toothed plate 5 to re-engage with the gear 9. After the two are engaged, the toothed plate 5 drives the gear 9 to rotate in the opposite direction, thereby driving the protrusions 21 at the top of the top plate 15 to move upwards, thereby lifting the shaped wallboard, and then completing the demolding process.

[0039] Embodiment Two: As shown in the figure, embodiment two is different from embodiment one in that a first bevel gear 18 is fixedly sleeved on the outer surface of each connecting rod 7. Two lead screws 19 are rotatably arranged on the top of the bottom plate 1 in the vertical direction, and the two lead screws 19 are threadedly matched with the two connecting plates 14 one by one. A second bevel gear 20 is coaxially and fixedly arranged on the top of each lead screw 19, and the second bevel gear 20 is engaged with the first bevel gear 18 one by one. Figures 4-5

[0040] By the engagement of the toothed plate 5 and the gear 9, the gear 9 is driven to rotate by the air cylinder 3, the gear 9 drives the first bevel gear 18 to rotate through the connecting rod 7, and the first bevel gear 18 drives the lead screw 19 to rotate through the second bevel gear 20. The rotation of the lead screw 19 drives the top plate 15 to slide up and down under the limitation of the guide plate 17, thereby driving the protrusions 21 to slide up and down.

[0041] The working principle of embodiment two is as follows: start the air cylinder 3, and control the telescopic shaft of the air cylinder 3 to elongate. The telescopic shaft of the air cylinder 3 drives the pressing plate 4 to move downwards, and the toothed plate 5 is driven to move synchronously in the process of the downward movement of the pressing plate 4. The movement of the toothed plate 5 drives the gear 9 to rotate, and the gear 9 drives the first bevel gear 18 to rotate through the connecting rod 7. The first bevel gear 18 drives the lead screw 19 to rotate through the second bevel gear 20, and the lead screw 19 drives the top plate 15 to move downwards through the connecting plate 14, thereby driving the protrusions 21 to move downwards in the clearance hole.

[0042] When the toothed plate 5 and the gear 9 are completely disengaged, the top of the protrusions 21 is just flush with the bottom of the mold cavity, and the protrusions 21 completely seal all the clearance holes. At this time, the bottom of the top plate 15 just abuts against the top of the disc 22, thereby limiting the top plate 15, and avoiding the sliding of the protrusions 21 in the process of extrusion molding.

[0043] When the formed wallboard needs to be taken out, the telescopic shaft of the air cylinder 3 is controlled to contract. The contraction of the telescopic shaft of the air cylinder 3 drives the pressing plate 4 to move upwards, and the upward movement of the pressing plate 4 gradually separates from the mold cavity. With the continuous upward movement of the pressing plate 4, the pressing plate 4 drives the toothed plate 5 to re-engage with the gear 9. After the two are engaged, the toothed plate 5 will drive the gear 9 to rotate in the opposite direction, thereby driving the protrusions 21 at the top of the top plate 15 to move upwards, thereby lifting the shaped wallboard, and then completing the demolding process. ​

[0044] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
