Description

Technical Field

[0001] This utility model relates to the field of acrylic sheet processing technology, specifically to a device for irregular forming of acrylic sheets. Background Technology

[0002] Acrylic sheet is an important, well-developed, malleable polymer material, commonly known as plexiglass. It possesses good transparency, chemical stability, and weather resistance, is easy to dye and process, and has a beautiful appearance, making it widely used in the construction industry. During the production and processing of acrylic sheets, it is necessary to perform irregular shaping processes; therefore, a device for irregular shaping acrylic sheets is required. However, current irregular shaping devices still have the following shortcomings:

[0003] For example, patent document CN214239509U discloses a device for irregular forming of acrylic sheets. After the forming process is completed, the pressure plate resets, driving the stop rod to pull the piston upward, thereby drawing the hot air inside the lower box into the air cylinder for storage through the air inlet and outlet pipes, thus completing the heat recovery. However, it is not convenient to disassemble and replace the mold, and it is not convenient to perform irregular forming processing of different shapes.

The lower end of the threaded fixing post 606 penetrates the inner side of the snap-fit ​​mounting block 605 and extends to the inner end of the snap-fit ​​mounting groove 604.

[0024] The specific operation is as follows: During use, the irregular concave mold 602 is fixed on the fixed base 1 by engaging with the mold receiving groove 601. At the same time, the irregular concave mold 602 is reinforced by engaging with the engagement groove 604 on the surface of the fixed base 1 by engaging with the engagement block 605.
