Description

Technical Field

[0001] This utility model relates to the field of sheet material processing technology, specifically to a vacuum pressing device for quartz stone sheets. Background Technology

[0002] Quartz stone slabs are a new type of artificial stone made of more than 80% quartz crystals, resin, and other trace elements. It belongs to the category of artificial stone and is made into large-format slabs by pressing them under certain physical and chemical conditions using special machines. It can also be customized and cut into different specifications and styles according to customer needs.

[0003] In the production of quartz stone slabs, vacuum pressing is a key process. Current vacuum pressing methods typically involve placing a mold containing the raw material into a vacuum press, closing the press chamber door, starting the vacuum pump to extract air from the mold, achieving a set vacuum level, and then applying pressure to the mold through the press's hydraulic system to produce the quartz stone slab. However, existing vacuum presses can only press one slab at a time in a vacuum environment, resulting in high processing costs and low production efficiency. Utility Model Content

[0032] Working principle and usage process of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-3 In use, the vacuum pressing device for quartz stone slabs of this utility model first places the mixed raw materials into the pressing mold groove 14, then closes the sealing box door 19, and uses the vacuum pump 18 to evacuate the vacuum pressing box 1. Then, the output end of the hydraulic push rod 17 extends downward to press the second module 3. The compression spring 11 on the guide rod 10 begins to contract into the interior of the first compression sleeve 8 and the second compression sleeve 9, and the pressing module 15 is pressed into the pressing mold groove 14, pressing the quartz stone raw materials and forming the quartz stone slab.

The top of the third module 4 is provided with a pressing groove 14, and the pressing module 15 provided between adjacent third modules 4 is pressed into the pressing groove 14. The pressing module 15 provided at the bottom of the third module 4 is pressed into the pressing groove 14 with the top opening of the first module 2. This can simultaneously compress multiple quartz stone slabs, greatly improving the processing efficiency of quartz stone slabs in a vacuum environment. After the quartz stone slabs are pressed and formed, the output end of the hydraulic push rod 17 is retracted, and the first module 2, the third module 4 and the second module 3 are supported in sequence by the compression spring 11. Then the vacuum pump 18 stops working, and the outside gas flows back into the vacuum pressing box 1 through the vacuum pump 18. Finally, the sealed box door 19 is opened, and the pressed quartz stone slabs are taken out.
