Description

Technical Field

[0001] This utility model relates to the field of PVC foam board technology, and in particular to a PVC foam board production shaping table. Background Technology

[0002] PVC foam board, also known as PVC foam board, Andy board, or foamed polyvinyl chloride board, is a lightweight board made from polyvinyl chloride (PVC) resin as the main raw material, with the addition of foaming agents and additives, and through a special foaming process. In the production process of PVC foam board, the main function of the shaping table is to cool and shape the molten material extruded from the extruder to ensure the dimensional stability and surface quality of the board.

[0003] However, during the use of the shaping table, the material enters the cavity for foaming and shaping. After shaping, it is removed by the staff. However, during the removal process, because the shaping cover plate covers the top of the cavity, the shaped foam board is completely placed inside the cavity and is in close contact with the inner wall of the cavity. There is no suitable gripping for the foam board, which makes it inconvenient for the staff to remove it from the cavity. The removal process is time-consuming and affects production efficiency.

[0004] To address this, a PVC foam board production shaping table is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a PVC foam board production shaping table to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PVC foam board production shaping table, including a mold, a base plate in the mold, and a mold cavity between the base plate and the mold; a demolding component is provided at the bottom end of the base plate, which can quickly remove the board from the mold cavity to improve production efficiency; the demolding component includes a support platform at the bottom end of the base plate, a first spring and a sliding rod in the support platform, and the sliding rod is fixedly connected to the base plate.

[0007] Preferably, the base plate is slidably connected in the mold cavity, the support platform has a receiving groove, and the first spring is fixedly connected in the receiving groove, and the slide rod is fixedly connected to the first spring.

[0008] Preferably, a bracket is fixedly connected to the mold, a telescopic component is fixedly installed on the bracket, and a mold cover plate is fixedly connected to the telescopic component. The mold cover plate is used to cooperate with the base plate to shape the sheet material in the mold cavity.

[0009] Preferably, a telescopic rod is fixedly installed on the mold cover plate, a pressure plate is fixedly connected to the bottom end of the telescopic rod, and a bending plate is fixedly connected to the bottom plate.

[0010] Preferably, a circular plate is fixedly installed on the telescopic rod, and a second spring is fixedly connected between the circular plate and the pressure plate, wherein the elastic force of the second spring is greater than that of the first spring.

[0011] Preferably, a connecting plate is fixedly connected to the support platform, a limiting groove is formed on the mold, and the connecting plate is slidably connected in the limiting groove.

[0012] Preferably, the mold is rotatably connected to a threaded rod, and the threaded rod is threadedly connected to a connecting plate. Two locking nuts are threadedly connected to the threaded rod, and the two locking nuts are located on both sides of the connecting plate.

[0013] The beneficial effects of this utility model are: This invention utilizes a demolding assembly that allows the foam board to be molded during the shaping process. After the mold cover moves downwards, it pushes the bending plate, causing the bottom plate to move downwards and adhere to the top surface of the support. This allows the sliding rod to enter the receiving groove, and the first spring contracts, generating a reaction force. The foaming process continues until the mold cover covers the top of the mold, completing the foaming process. After the mold cover moves upwards and resets, the bottom plate, under the reaction force of the first spring, pushes the foam board in the mold cavity upwards and removes it from the mold cavity, thus achieving a demolding effect. This facilitates direct removal by workers, improving the convenience of removing the foam board.

[0014] This invention allows the connecting plate to be adjusted by rotating the threaded rod, which in turn allows the support platform to move the base plate to adjust its position. The change in the position of the base plate in the mold changes the depth of the mold cavity. Therefore, the entire device can facilitate the foaming and shaping of foam boards of different thicknesses and models. At the same time, it can still work with the demolding component to achieve the demolding effect when removing foam boards of different models. Attached Figure Description

[0018] 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 specific embodiments.

[0020] As shown in the figures, a specific embodiment of this utility model provides a PVC foam board production shaping table, including a mold 1, a base plate 2 in the mold 1, and a mold cavity 3 between the base plate 2 and the mold 1. After material is injected into the mold cavity 3 by an external injection device, it gradually foams inside to form a foam board. The bottom end of the base plate 2 is provided with a demolding component. After the material gradually foams in the mold cavity 3 to form a foam board, when it needs to be removed from the mold cavity 3, since the shaped foam board is completely placed inside the cavity and the foam board is in close contact with the inner wall of the cavity, there is no suitable gripping for the foam board, making it inconvenient for the staff to remove it. However, by setting a demolding component, it is more convenient to remove the foam board during the demolding process. The foam board inside the mold cavity 3 can automatically detach outward, making it easy for the staff to remove it directly. The demolding component includes a support platform 4 at the bottom end of the base plate 2, and a first spring 5 and a sliding rod 6 are provided in the support platform 4. The sliding rod 6 is fixedly connected to the base plate 2.

[0021] like Figure 2 , Figures 4 to 5As shown, specifically, the base plate 2 is slidably connected to the mold cavity 3, the support platform 4 has a receiving groove 7, and the first spring 5 is fixedly connected to the receiving groove 7. The slide rod 6 is fixedly connected to the first spring 5. A bracket 8 is fixedly connected to the mold 1, and a telescopic component 9 is fixedly installed on the bracket 8. A mold cover plate 10 is fixedly connected to the telescopic component 9. The mold cover plate 10 is used to cooperate with the base plate 2 to shape the sheet material in the mold cavity 3. When shaping the foamed board, external equipment, such as an automatic injection equipment, injects the material into the mold cavity 3, so that it is positioned on the base plate. After the material is injected into the top of mold 1, the operator activates the control switch, which causes the controller to activate the telescopic component 9 to push the bottom mold cover plate 10 downwards and gradually cover the top of mold 1. The telescopic component 9 is a prior art technology, such as a cylinder or other pushing mechanism. A telescopic rod 11 is fixedly installed on the mold cover plate 10, and a pressure plate 12 is fixedly connected to the bottom end of the telescopic rod 11. A bending plate 13 is fixedly connected to the bottom plate 2, and a circular plate 14 is fixedly installed on the telescopic rod 11. A second spring 15 is fixedly connected between the circular plate 14 and the pressure plate 12. The elastic force of spring 15 is greater than that of the first spring 5. During the downward movement of the mold cover plate 10, the mold cover plate 10 pushes the telescopic rod 11 and the bottom pressure plate 12 downwards. The pressure plate 12 gradually contacts the bottom bending plate 13. At this time, the bending plate 13 moves downwards under the pushing effect of the pressure plate 12. The downward movement of the bending plate 13 pulls the bottom plate 2 downwards. The downward movement of the bottom plate 2 pushes the bottom sliding rod 6 downwards. The sliding rod 6 gradually enters the receiving groove 7, and the first spring 5 contracts under force. It is worth noting that the bottom... When plate 2 moves downward, it will be resisted by the first spring 5. During the continuous downward movement of the mold cover plate 10, the thrust generated is sufficient to cause the first spring 5 to contract, overcoming the resistance generated by it and causing the bottom plate 2 to move downward. In this process, since the elastic force of the second spring 15 is greater than that of the first spring 5, when the telescopic rod 11 pushes the bending plate 13 downward through the pressure plate 12 at the bottom, the second spring 15 is sufficient to overcome the resistance brought by the first spring 5, so that the second spring 15 can remain stable and will not contract.

[0022] As the base plate 2 gradually moves downwards to meet the top surface of the support platform 4, it is blocked by the support platform 4 and cannot move further downwards. The sliding rod 6 enters the receiving groove 7, and the first spring 5 contracts, generating a reaction force. While the base plate 2 cannot move further downwards, the mold cover plate 10 does not completely cover the top of the mold 1. At this time, the telescopic assembly 9 continues to push the mold cover plate 10 downwards, but the inability of the base plate 2 to move downwards keeps the bending plate 13 stable and unable to move downwards. Therefore, under the pushing force of the mold cover plate 10, the telescopic rod 11 contracts, and the second spring 15 contracts. As the telescopic rod 11 gradually contracts, the mold cover plate 10 has space to move downwards and cover the mold 1. The top seals the mold 1, allowing the material to foam in the mold cavity 3 to form a foam board. After the foam board is shaped, the reverse drive telescopic component 9 moves the mold cover plate 10 upward to reset. As the mold cover plate 10 moves upward, it drives the telescopic rod 11 to move upward. The second spring 15 gradually pushes the telescopic rod 9 to extend and reset under the reaction force. After the pressure plate 12 is separated from the bending plate 13, the bottom plate 2 is not under pressure and will push the slide rod 6 upward under the reaction force of the first spring 5, pushing the bottom plate 2 to move upward. The upward movement of the bottom plate 2 will push the foam board in the mold cavity 3 to move upward and out of the mold cavity 3 by a certain distance, so that the top of the foam board is higher than the top of the mold 1, achieving the purpose of demolding, thus making it easy for the staff to take it out directly.

[0023] like Figures 2 to 3As shown, specifically, a connecting plate 16 is fixedly connected to the support platform 4, and a limiting groove 17 is formed on the mold 1. The connecting plate 16 is slidably connected in the limiting groove 17. A threaded rod 18 is rotatably connected to the mold 1, and the threaded rod 18 is threadedly connected to the connecting plate 16. Two locking nuts 19 are threadedly connected to the threaded rod 18, and the two locking nuts 19 are located on both sides of the connecting plate 16. The entire device can adjust the thickness of the foam board to obtain foam boards of different types. By rotating the threaded rod 18, the connecting plate 16 moves downward in the limiting groove 17. The downward movement of the connecting plate 16 can drive the support platform 4 to move downward, and the downward movement of the support platform 4 can drive the bottom plate 2 at the top to move downward. After the movement, its position is adjusted, and the depth of the mold cavity 3 changes. Therefore, the thickness of the foamed board formed after the injected material foams is changed. It is worth noting that after the position of the bottom plate 2 changes, after the mold cover plate 10 moves downward, the bottom plate 2 can also move downward to fit the support platform 4 according to the above process, and the demolding effect will still be formed. The thickness of the foamed board formed in the whole device is the height between the mold cover plate 10 and the bottom plate 2 when they fit the top surface of the support platform 4 after the mold cover plate 10 covers the top of the mold 1. After the connecting plate 16 adjusts the position of the bottom plate 2, the threaded rod 18 can be locked by rotating the two locking nuts 19 to prevent the threaded rod 18 from being unstable and slightly rotating.
