[0002] Acrylic, also known as PMMA or organic glass, is an important, early-developed plastic polymer material. It features excellent transparency, chemical stability, weather resistance, easy dyeing, ease of processing, and an attractive appearance, making it widely used in the construction industry.

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0025] First, combine Figure 1 Figure 4An acrylic forming device according to an embodiment of the present invention is described, which is used to press-form an acrylic plate.

[0026] like Figure 1~Figure 2 As shown, an acrylic forming device according to an embodiment of the present invention comprises: a mold assembly 1, a die assembly 2 and a stripping assembly 3;

[0027] The mold assembly 1 includes: a mold base plate 11 and a mold body 12;

[0028] The mold base 11 is arranged around the periphery of the mold body 12. The mold body 12 is arranged according to the molding shape of the material, and the material is placed on the mold body 12;

[0029] The die assembly 2 is used to press the material to shape it;

[0030] The material stripping assembly 3 includes: a material stripping spring 31 and a material stripping plate 32;

[0031] The stripper plate 32 is provided on the mold bottom plate 11 , the edge of the material is located on the stripper plate 32 , and the stripper spring 31 is provided between the stripper plate 32 and the mold bottom plate 11 , and the stripper spring 31 is used to lift the formed material.

[0032] The material to be formed is placed on the mold body 12, and the die assembly 2 presses the material. The material stripping spring 31 is compressed by the pressure of the die assembly 2. After the material is pressed, the elastic force of the material stripping spring 31 pushes the material stripping plate 32 to lift the material upward, thereby increasing the gap between the material and the mold body 12, making it easier to remove the material from the mold assembly 1.

[0033] like Figure 4 As shown, the material stripping assembly 3 includes: a guide tube 33;

[0034] The guide tube 33 is provided below the stripping plate 32 , and the mold bottom plate 11 is provided with a guide groove, which is provided corresponding to the guide tube 33 .

[0035] When the stripper plate 32 is moved by the pressure of the die assembly 2 and the elastic force of the stripper spring 31, the guide tube 33 slides in the guide groove of the mold bottom plate 11 to prevent the stripper plate 32 from shaking during movement and affecting the molding shape of the material.

[0036] like Figures 2 to 4 As shown, the die assembly 2 includes: a top plate 21, a pressing plate 22 and a support rod 23;

[0037] The top plate 21 is located above the mold assembly 1 , the support rod 23 is located below the top plate 21 , the pressing plate 22 is located at the lower end of the support rod 23 , and the pressing plate 22 is provided corresponding to the mold bottom plate 11 .

[0038] The pressing plate 22 only presses the edge of the material, so that the middle area of the material changes with the shape of the mold body 12. In this embodiment, an upper mold can be set under the top plate 21. The shape of the upper mold is matched with the shape of the mold body 12, so that the molding device can form more diverse shapes.

[0039] like Figures 1 to 4 As shown, it includes: a driving mechanism 4, which includes: at least two driving cylinders 41 and a fixing plate 42;

[0040] The fixing plate 42 is arranged above the die assembly 2, and the driving cylinder 41 is arranged on the die assembly 2. The two driving cylinders 41 are respectively arranged at both ends of the die assembly 2. The driving cylinder 41 is used to drive the die assembly 2 to press the material.

[0041] The driving mechanism 4 further includes: a synchronization rack 43 and a synchronization gear 44;

[0042] The fixed plate 42 has a synchronization opening, a synchronization rack 43 is provided on the die assembly 2 and passes through the synchronization opening, and a synchronization gear 44 is provided in the synchronization opening. The synchronization gear 44 is provided corresponding to the synchronization rack 43 and is rotationally connected to the fixed plate 42.

[0043] The fixed plate 42 is fixed to the top of the die assembly 2, and the two driving cylinders 41 simultaneously drive the die assembly 2 to move for pressing. The synchronous gear 44 rotates on the synchronous rack 43, so that the two ends of the die assembly 2 move synchronously, avoiding the die assembly 2 from being in a tilted state when pressing the material, ensuring that the shape of the material pressed meets the requirements.

[0044] Above, refer to Figures 1 to 4 An acrylic forming device according to an embodiment of the present invention is described. In this embodiment, when the die assembly 2 presses the material, the material stripping spring 31 is compressed by the pressure of the die assembly 2. After the material is pressed, the elastic force of the material stripping spring 31 pushes the material stripping plate 32 to lift the material upward, thereby increasing the gap between the material and the mold body 12, making it easier to remove the material from the mold assembly 1.
