Description

Technical Field

[0001] This utility model belongs to the field of foam board mold technology, and in particular relates to a mold for producing supercritical foam boards. Background Technology

[0002] Supercritical foam board is a high-performance porous material prepared by supercritical fluid foaming technology. Its core process is to dissolve gas in a polymer substrate under supercritical conditions, and then expand the gas by rapidly depressurizing to form a uniform microporous structure. It has the characteristics of being environmentally friendly and efficient, and can precisely control the size and distribution of the foam cells.

[0003] Currently, existing foam board molding molds typically require multiple bolts to connect to the processing table. Installation and disassembly require tools to operate on each bolt individually, which is cumbersome and time-consuming. Mold maintenance and replacement require a long downtime, affecting the production rate of foam boards.

[0004] To address the aforementioned issues, this application proposes a mold for producing supercritical foam boards. Utility Model Content

[0005] The purpose of this invention is to provide a mold for producing supercritical foam boards, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a mold for producing supercritical foam boards, comprising a horizontal top plate, a processing table, and a base arranged sequentially from top to bottom. It also includes a positioning rod fixed to the bottom of the mold body and passing through a positioning hole in the processing table. The positioning rod has a slot for inserting a block. The block is fixed to a sliding block via a connecting plate and a smoothing rod. A lifting seat is located below the processing table. Inclined guide surfaces are provided on the bottom surface of the lifting seat and the top surface of the sliding block. The lifting seat moves downwards, causing the sliding block to move laterally, thereby separating the block from the slot via the smoothing rod and the connecting plate. A moving block is positioned above the lifting seat. A template is located inside the mold body. Both the processing table and the mold body have clearance holes. The moving block is used to move the lifting seat and the template.

[0008] Furthermore, the bottom end of the processing table is fixedly connected to the base via a support leg, and the support leg is fixedly connected to the second fixed plate. The second fixed plate is penetrated by the second telescopic rod and is slidably connected to the second telescopic rod. The two ends of the second telescopic rod are fixedly connected to the limiting block and the first connecting plate, respectively. A spring is wound around the second telescopic rod, and the two ends of the spring are fixedly connected to the first connecting plate and the second fixed plate, respectively.

[0009] Furthermore, a second cylinder with its output end fixedly connected to the bottom end of the moving block is installed on the top surface of the base, and the output shaft of the second cylinder passes through the through hole opened in the lifting seat.

[0010] Furthermore, a telescopic rod and a spring are fixed between the lifting seat and the processing table, and the spring is wound around the telescopic rod. The bottom height of the telescopic rod is greater than the bottom height of the sliding block.

[0011] Furthermore, the mold body has a receiving groove, and the receiving groove is fixedly connected to the bottom end of the telescopic rod and the spring. The top end of the telescopic rod and the spring is fixedly connected to the template, and the spring is wrapped around the outside of the telescopic rod.

[0012] Furthermore, the smooth rod passes through the guide sleeve and is slidably connected to the guide sleeve, and the guide sleeve is fixedly connected to the bottom end of the processing table through a fixing block.

[0013] Furthermore, a slot two is provided on one side of the lifting seat to insert the second plug block. The second plug block is fixedly connected to the second connecting plate, and the second connecting plate is rotatably connected to the screw. A fixing plate one is fixedly provided on the bottom surface of the processing table and threadedly connected to the screw. A guide rod is fixedly provided on one side of the second connecting plate and slidably connected to the first fixing plate.

[0014] Furthermore, a support column is fixed between the processing table and the horizontal top plate, and a cylinder with its output end fixedly connected to the lifting plate is installed on the top surface of the horizontal top plate.

[0015] This utility model has the following beneficial effects:

[0016] This invention uses a lifting seat to move downwards so that its guide surface contacts the guide surface of the sliding block. Then, the sliding block is pushed to move laterally, which, through the smooth rod and connecting plate, causes the insert block to separate from the slot, releasing the fixation of the positioning rod. This allows the mold body to be easily removed for inspection or replacement, effectively improving the disassembly speed of the mold body.

[0017] This invention uses the upward movement of the moving block to push the lifting seat downward, which in turn pushes the sliding block to move laterally, thus achieving automatic unlocking of the mold body. Furthermore, the upward movement of the moving block can drive the template upward to push out the foam board, thereby improving the demolding speed of the foam board.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating 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.

[0031] Please see Figure 1 - Figure 7 As shown, this utility model is a mold for producing supercritical foam board, including a horizontal top plate 3, a processing table 1, and a base 2 arranged sequentially from top to bottom. It also includes a positioning rod 5, which is fixed to the bottom end of the mold body 4 and passes through the positioning hole 101 opened in the processing table 1. The positioning rod 5 has a slot 501 to be inserted into a block 8. The block 8 is fixed to a sliding block 12 through a connecting plate 801 and a smooth rod 13. A lifting seat 10 is provided below the processing table 1. The bottom surface of the lifting seat 10 and the top surface of the sliding block 12 are both provided with inclined guide surfaces. The lifting seat 10 moves down and drives the sliding block 12 to move laterally, thereby separating the block 8 from the slot 501 through the smooth rod 13 and the connecting plate 801. A moving block 16 is provided above the lifting seat 10. A template 401 is provided inside the mold body 4. Both the processing table 1 and the mold body 4 have clearance holes. The moving block 16 is used to drive the lifting seat 10 and the template 401 to move.

[0032] This embodiment provides a mold for producing supercritical foam board. The positioning rod 5 is fixed and unlocked by the insertion and separation of the insert block 8 and the slot 501, thereby fixing and unlocking the mold body 4, effectively improving the disassembly and installation speed of the mold body 4. When the moving block 16 pushes the lifting seat 10 down, the guide surfaces of the lifting seat 10 and the sliding block 12 interact, pushing the sliding block 12 to move laterally, causing the insert block 8 to disengage from the slot 501, releasing the mold lock. During foam board production, the moving block 16 pushes the template 401 up to push the foam board out of the mold body 4, improving the demolding speed of the foam board. The diameter of the clearance hole opened on the processing table 1 and the mold body 4 is larger than the outer diameter of the moving block 16.

[0033] The bottom of the processing table 1 is fixedly connected to the base 2 via a support leg, and the support leg is fixedly connected to the second fixed plate 11. The second fixed plate 11 is slidably connected to the second telescopic rod 9. The two ends of the second telescopic rod 9 are fixedly connected to the limiting block 901 and the connecting plate 801, respectively. A spring is wound around the second telescopic rod 9, and the two ends of the spring are fixedly connected to the connecting plate 801 and the second fixed plate 11, respectively. The support leg is reinforced by the second fixed plate 11. When the mold body 4 is installed, the moving block 16 moves upward and separates from the lifting seat 10. The spring drives the connecting plate 801 to reset the insertion block 8 and insert it into the slot 501, thereby achieving automatic locking.

[0034] The base 2 has a cylinder 15 whose output end is fixed to the bottom end of the moving block 16. The output shaft of the cylinder 15 passes through the through hole 1002 opened in the lifting seat 10. The diameter of the through hole 1002 is larger than the outer diameter of the output shaft of the cylinder 15 and smaller than the outer diameter of the moving block 16. The cylinder 15 drives the moving block 16 to move vertically.

[0035] The lifting seat 10 and the processing table 1 are fixedly connected by a telescopic rod 3 18 and a spring, with the spring wrapped around the telescopic rod 3 18. The bottom height of the telescopic rod 3 18 is greater than the bottom height of the sliding block 12. When the lifting seat 10 descends, because the bottom height of the telescopic rod 3 18 is greater than the bottom height of the sliding block 12, the top surface of the lifting seat 10 will always be above the bottom surface of the lifting seat 10, preventing the lifting seat 10 from separating from the sliding block 12 when it moves down. The telescopic rod and the spring prevent the moving block 16 from having a rigid collision with the lifting seat 10 when it moves down. After the moving block 16 separates from the lifting seat 10, the lifting seat 10 automatically resets under the action of the spring.

[0036] The mold body 4 has a receiving groove 402, which is fixedly connected to the bottom end of the telescopic rod 403 and the spring. The top end of the telescopic rod 403 and the spring is fixedly connected to the template 401, and the spring is wrapped around the telescopic rod 403. The spring acts as a buffer to prevent the moving block 16 from rigidly colliding with the template 401. After the foam board is pushed out of the mold body 4 by the moving block 16, the worker removes the foam board, and then the moving block 16 moves down, and the spring drives the template 401 to reset.

[0037] The smoothing rod 13 passes through the guide sleeve 14 and is slidably connected to the guide sleeve 14. The guide sleeve 14 is fixed to the bottom of the processing table 1 through the fixing block 1401. The guide sleeve 14 guides the movement of the smoothing rod 13, ensuring that the smoothing rod 13 can move laterally stably.

[0038] The lifting seat 10 has a slot 1001 on one side for inserting the second insertion block 17. The second insertion block 17 is fixedly connected to the second connecting plate 1701, and the second connecting plate 1701 is rotatably connected to the screw 19. The bottom surface of the processing table 1 is fixedly provided with a fixing plate 102, which is threadedly connected to the screw 19. A guide rod 20 is fixedly provided on one side of the second connecting plate 1701 and slidably connected to the fixing plate 102. A crank handle is provided on the side of the screw 19 away from the second insertion block 17. After the mold body 4 is installed on the processing table 1, the lifting seat 10 is fixed by inserting the second insertion block 17 into the slot 1001 to prevent the moving block 16 from pushing the lifting seat 10 down. When disassembling the mold body 4, the screw 19 is rotated by rotating the crank handle, which drives the second insertion block 17 to separate from the slot 1001 through the second connecting plate 1701. The guide rod 20 guides the movement of the second insertion block 17.

[0039] A support column is fixed between the processing table 1 and the horizontal top plate 3. A cylinder 7 with its output end fixed to the lifting plate 6 is installed on the top surface of the horizontal top plate 3. The cylinder 7 drives the lifting plate 6 to move down and close with the mold body 4.

[0040] Understandably, this invention enables the rapid disassembly and installation of the mold body 4, and secondly, it lifts up the foam board to improve the demolding speed.

[0041] A specific application of the operation process of this embodiment is as follows: When processing foam board, insert block 8 is inserted into slot 501, and insert block 17 is inserted into slot 1001. During demolding, cylinder 15 drives moving block 16 to move upward and lift foam board through template 401. When disassembling mold body 4, rotating the crank handle causes screw 19 to separate insert block 17 from slot 1001. Then, cylinder 15 drives moving block 16 downward, pushing lifting seat 10 to move sliding block 12 laterally, thereby separating insert block 8 from slot 501. Then, mold body 4 can be removed.

[0042] When the mold body 4 is installed, the positioning rod 5 and the positioning hole 101 are inserted to achieve quick positioning of the mold body 4. Then, the second cylinder 15 is driven to move the moving block 16 upward. The connecting plate 801 and the insert block 8 are reset under the action of the spring. The insert block 8 is inserted into the slot 501 to achieve quick fixation of the mold body 4. Then, the lifting seat 10 is reset under the spring. The rotating handle drives the insert block 17 to be inserted into the slot 1001 to fix and limit the lifting seat 10, thus completing the quick installation of the mold body 4.
