[0002] EPS board (also known as benzene board) is the abbreviation of expandable polystyrene board. It is a polystyrene foam plastic board with a closed-cell structure, which is made by heating and pre-foaming expandable polystyrene beads and then heating and molding them in a mold. It is made from raw materials through processes such as pre-expansion, ripening, molding, drying, and cutting. It can be made into foam products with different densities and shapes, and can also produce foam boards with various thicknesses. It is widely used in fields such as construction, insulation, packaging, refrigeration, daily necessities, and industrial casting. It can also be used for the manufacture of exhibition venues, product showcases, advertising signs, and toys. To meet the national building energy conservation requirements, it is mainly used for external wall external insulation, internal wall insulation, and floor heating of exterior walls.

[0003] During the processing of EPS foam boards, they need to be processed through ripening and molding. This process is carried out in a special mold. After ripening and molding, it is necessary to take out the large-volume whole foam board from the molding mold. Since the outer surface of the foam board is relatively rough and the volume is large, a large frictional force will be generated between the foam board and the surface of the mold during the process of taking it out, thus affecting the demoulding speed.

Specific embodiments

[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, 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 only used to explain the present utility model and are not used to limit the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a rapid demoulding device for EPS foam boards, including a bottom plate 1. A support ring 2 is vertically fixedly connected to the upper surface of the bottom plate 1. A bottom mold mounting plate 3 is horizontally fixedly connected to the top end of the support ring 2. Side mold mounting plates 4 are hinged to the front, rear, both sides of the bottom mold mounting plate 3 through hinges. A vertical seat 5 is vertically fixedly connected to the rear part of the upper surface of the bottom plate 1. An extension plate 6 extending forward is horizontally fixedly connected to the upper surface of the vertical seat 5. A plurality of mounting holes are vertically and throughly opened on the upper surface of the extension plate 6. A first electric control telescopic rod 7 is vertically fixedly connected to the inside of each of the plurality of mounting holes. The bottom ends of the plurality of first electric control telescopic rods 7 are horizontally fixedly connected to a top mold mounting plate 8;

[0020] The bottom mold mounting plate 3, the plurality of side mold mounting plates 4 and the top mold mounting plate 8 are combined to form a rectangular frame.

[0021] The outer surfaces of the plurality of side mold mounting plates 4 are all hinged with second electric control telescopic rods 12, and the other ends of the plurality of second electric control telescopic rods 12 are all hinged to the upper surface of the bottom plate 1.

[0022] In this embodiment, when the device is in use, the plurality of side mold mounting plates 4 are driven to rotate by the plurality of second electric control telescopic rods 12. When the plurality of second electric control telescopic rods 12 extend, they can push the plurality of side mold mounting plates 4 to rotate inwards until the plurality of side mold mounting plates 4 and the bottom mold mounting plate 3 are combined to form a frame with an open top. Then, raw materials are added inwards and the top mold mounting plate 8 is pressed down to be combined with the frame. After that, curing and forming can be carried out. After the forming is completed, when the plurality of second electric control telescopic rods 12 contract, they will drive the plurality of side mold mounting plates 4 to rotate outwards and separate from the formed foam board. At this time, when demoulding the foam board, it will not be affected by friction, thereby improving the demoulding efficiency.

[0023] The top mold mounting plate 8 is controlled to rise and fall by the extension and contraction of the plurality of first electric control telescopic rods 7, so as to realize the combination and separation with the plurality of side mold mounting plates 4.

[0024] Further, a bottom template 9, a side template 10, and a top template 11 are respectively fixedly connected to the upper surface of the bottom mold mounting plate 3, the inner surfaces of the plurality of side mold mounting plates 4, and the lower surface of the top mold mounting plate 8.

[0025] In this embodiment, the bottom template 9, the side template 10, and the top template 11 are combined under the action of the bottom mold mounting plate 3, the plurality of side mold mounting plates 4, and the top mold mounting plate 8 to form a rectangular mold frame for curing and forming the foam board.

[0026] Further, a plurality of through holes 13 penetrating through to the upper surface of the bottom template 9 are vertically formed in the lower surface of the bottom mold mounting plate 3 and inside the support ring 2. The bottom ends of the plurality of through holes 13 are outwardly expanded to form threaded holes, and threaded columns 14 are threadedly connected to the inside of the plurality of threaded holes. The top ends of the plurality of threaded columns 14 are fixedly connected to ejector posts 15 whose outer diameters are adapted to the inner diameters of the through holes 13.

[0027] A plurality of motors 16 respectively corresponding to the plurality of threaded columns 14 are vertically fixedly connected to the upper surface of the bottom plate 1 and inside the support ring 2. The top ends of the output shafts of the plurality of motors 16 are vertically fixedly connected to telescopic rods, and the other ends of the plurality of telescopic rods are respectively fixedly connected to the bottom ends of the plurality of threaded columns 14.

[0028] In this embodiment, after the plurality of side mold mounting plates 4 are opened, the top mold mounting plate 8 will also rise under the action of the first electric control telescopic rod 7 to separate from the foam board. At this time, the plurality of motors 16 will operate. By the operation of the motors 16, the threaded columns 14 can be driven to rotate. During the rotation of the threaded columns 14, the threaded columns 14 will perform vertical displacement through the threaded holes, so as to drive the ejector posts 15 to synchronously move vertically. When the ejector posts 15 rise, the foam board can be lifted from the upper surface of the bottom template 9, so that it is completely separated from the mold.

[0029] During the curing process, the horizontal plane where the top ends of the ejector posts 15 are located is at the same horizontal plane as the upper surface of the bottom template 9.

[0030] Further, a plurality of support pads are fixedly connected to the bottom end of the bottom plate 1.

[0031] In this embodiment, the support pads play a supporting role.

[0032] Working principle and usage process of the present utility model: After the present utility model is installed, when the device is in use, multiple second electric control telescopic rods 12 drive multiple side mold mounting plates 4 to rotate. When the multiple second electric control telescopic rods 12 extend, they can push the multiple side mold mounting plates 4 to rotate inwards until the multiple side mold mounting plates 4 and the bottom mold mounting plate 3 are combined to form a frame with an open top. Then, raw materials are added inwards and the top mold mounting plate 8 is pressed down to be combined with the frame. After that, curing and forming can be carried out. After the forming is completed, when the multiple second electric control telescopic rods 12 contract, they will drive the multiple side mold mounting plates 4 to rotate outwards and separate from the formed foam board. At this time, when demolding the foam board, it will not be affected by friction, thereby improving the demolding efficiency.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
