Abstract
Description
Technical Field
[0001] This application relates to the field of foam board molds, and more particularly to a polystyrene foam board mold. Background Technology
[0002] Polystyrene foam board, also known as foam board or EPS board, is a white material made from expandable polystyrene beads containing volatile liquid foaming agents, which are pre-expanded by heating and then molded in a mold. Polystyrene foam board has a micro-closed-cell structure, with a uniform and flat surface and a completely closed-cell honeycomb structure inside. This structure gives polystyrene foam board excellent thermal insulation, sound insulation, and moisture-proof properties, as well as the characteristics of being high-pressure resistant, lightweight, non-absorbent, airtight, wear-resistant, and non-degradable.
[0003] Polystyrene foam boards are widely used in modern society's production and daily life. However, during the production and processing of polystyrene foam boards through molds, due to the thermoplastic molding process, the polystyrene foam boards tend to stick to the mold after production, making it difficult to demold them easily. This results in reduced production and processing efficiency and compromised integrity of the polystyrene foam boards.
[0004] Regarding the aforementioned technologies, the inventors believe that polystyrene foam boards have the drawback of inconvenient demolding.
[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0023] This application discloses a polystyrene foam board mold. (Refer to...) Figures 1-5 A polystyrene foam board mold includes: a main mold 5 and a mold cavity 12 integrally formed inside the main mold 5 for use in the production of polystyrene foam boards; a demolding mechanism disposed on the main mold 5 for demolding polystyrene foam boards produced inside the main mold 5; a support mechanism disposed at the bottom of the main mold 5 for supporting the production of polystyrene foam boards; and an adjustment mechanism fixedly disposed on the main mold 5 for sliding and lifting the main mold 5.
[0024] By setting up a main mold 5, polystyrene foam board production and processing can be completed in the mold cavity 12 inside the main mold 5. A receiving plate 8 is set below the main mold 5 to facilitate the production of polystyrene foam board in the auxiliary main mold 5. At the same time, the hydraulic rod 2 set at the top of the main mold 5 can lift the main mold 5 upward, while the hydraulic rod 1 keeps the demolding plate 14 stationary, so that the demolding plate 14 can quickly push out the polystyrene foam board produced inside the main mold 5, achieving the purpose of convenient demolding.
[0025] Reference Figure 4 and Figure 5 The demolding mechanism includes a demolding plate 14, a sealing sleeve 7, and a hydraulic rod 1;
[0026] By sliding a demolding template 14 inside the main mold 5, after the polystyrene foam board is produced in the mold cavity 12 inside the main mold 5, the produced polystyrene foam board can be completely ejected by the demolding template 14, which facilitates the quick and complete demolding of the polystyrene foam board. A sealing sleeve 7 is fixedly installed on the demolding template 14, and a hydraulic rod 1 is fixedly connected to the demolding template 14 through the sealing sleeve 7. When the demolding template 14 is used, the hydraulic rod 11 drives the demolding template 14 to extend and retract, and the demolding template 14 pushes the polystyrene foam board out of the interior of the main mold 5 to complete the demolding operation.
[0027] Meanwhile, the sealing sleeve 7, which fixes the hydraulic rod 1 to the demolding template 14, can seal the gap between the main mold 5 and the demolding template 14, preventing material leakage when polystyrene foam board is produced and molded inside the main mold 5.
[0028] Reference Figure 1 and Figure 2 The support mechanism includes a receiving plate 8, a support frame 9, a sealing groove 10, and a connector 11;
[0029] By providing a receiving plate 8 below the main mold 5 and opening a sealing groove 10 on the top of the receiving plate 8, the main mold 5 can be engaged inside the sealing groove 10 when connected to the top of the receiving plate 8, and the side wall of the main mold 5 can be sealed to the mold cavity 12, thereby enabling the production of polystyrene foam board inside the main mold 5.
[0030] Meanwhile, support frames 9 are fixedly connected to the four corners of the bottom of the receiving plate 8, so that several support frames 9 can be used to stably support the receiving plate 8. A connector 11 is fixedly installed at the middle of the bottom of the receiving plate 8. When polystyrene foam boards need to be mass-produced, the receiving plate 8 can be connected to the conveyor belt through the connector 11. This makes it convenient for the main mold 5 to complete the demolding with the demolding template 14 after the polystyrene foam board is produced. The polystyrene foam board can then be quickly transferred through the receiving plate 8, the connector 11 and the conveyor belt.
[0031] Reference Figure 2 and Figure 3 The adjustment mechanism includes a hydraulic rod 2, a connecting shaft 3, and a connecting frame 4;
[0032] By fixing connecting frames 4 at the top four corners of the main mold 5, and sliding connecting shafts 3 in the inner wall of the connecting frames 4, the main mold 5 can be raised and lowered by several connecting shafts 3 and connecting frames 4. Several limiting slide bars 13 are fixedly connected to the side wall of the connecting shafts 3, so that the several limiting slide bars 13 can slide and limit the connecting shafts 3 and connecting frames 4, thereby facilitating the stable sliding adjustment of the main mold 5 through the connecting shafts 3 and connecting frames 4.
[0033] Meanwhile, two hydraulic rods 2 are symmetrically fixedly connected to the top of the main mold 5, so that the main mold 5 can be raised and lowered. The main mold 5 can be driven by the two hydraulic rods 2, and then raised and lowered in conjunction with several connecting frames 4. When the polystyrene foam board inside the main mold 5 needs to be demolded, the two hydraulic rods 2 will drive the main mold 5 to move upward, so that the hydraulic rod 1 will drive the demolding template 14 to have a downward pushing force, so that the polystyrene foam board will be separated from the inside of the main mold 5 and placed on the receiving plate 8. Then, the demolding template 14 will be retracted into the mold cavity 12 by the hydraulic rod 1 to carry out the next polystyrene foam board production and processing.
[0034] Secondly, mounting parts 15 are fixedly connected to the top of hydraulic rod 1, hydraulic rod 2, and connecting shaft 3, so that hydraulic rod 1, hydraulic rod 2, and connecting shaft 3 can be fixedly installed on buildings or processing equipment through the mounting parts 15 for use.
[0035] The implementation principle of a polystyrene foam board mold according to this application embodiment is as follows: A demolding template 14 is slidably connected inside the main mold 5, allowing the polystyrene foam board to be completely ejected from the mold cavity 12 inside the main mold 5 after production. This facilitates quick and complete demolding of the polystyrene foam board. A sealing sleeve 7 is fixedly installed on the demolding template 14, and a hydraulic rod 1 is fixedly connected to the demolding template 14 through the sealing sleeve 7. During demolding, the hydraulic rod 11 drives the demolding template 14 to extend and retract, thus ejecting the polystyrene foam board from the interior of the main mold 5. The main mold 5 is symmetrically fixed to the top of the main mold 5 to complete the demolding operation. Two hydraulic rods 2 are fixedly connected to the top of the main mold 5, so that the main mold 5 can be raised and lowered. The main mold 5 can be driven by the two hydraulic rods 2, and in conjunction with several connecting frames 4, the polystyrene foam board inside the main mold 5 needs to be demolded. The two hydraulic rods 2 will drive the main mold 5 to move upward, so that the hydraulic rod 1 will drive the demolding template 14 to push downward, so that the polystyrene foam board will be separated from the inside of the main mold 5 and placed on the receiving plate 8. Then, the hydraulic rod 1 will retract to retract the demolding template 14 into the mold cavity 12 for the next polystyrene foam board production process.
