Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1 to 4 The illustrated air-permeable pressure plate includes a main body 10, which has an upper surface 12 and a lower surface 11. The upper surface 12 of the main body 10 is fixedly installed at the output end of a press. The lower surface 11 has a plurality of first transverse airflow grooves 111 and a plurality of first longitudinal airflow grooves 112, which are connected. A filter screen 14 is also sealed and installed on the lower surface 11, covering the first transverse airflow grooves 111 and the first longitudinal airflow grooves 112, thereby forming a first airflow channel between the filter screen 14 and the lower surface 11. Air holes 1 are also provided on the side of the main body 10. 3. The air hole 13 is connected to the first longitudinal airflow groove 112. The filter screen 14 has a filtration accuracy of 1μm to 5μm, so that the filter screen 14 can filter out the discharged air and block the powder material. During pressing, the air-permeable pressure plate is driven by the press to descend and press the powder material in the lower die. During the pressing process, the air in the lower die can be discharged from the filter screen 14 through the first transverse airflow groove 111 / first longitudinal airflow groove 112 and from the air hole 13, ensuring that the air in the lower die is completely discharged so as to smoothly and stably press to obtain the heat insulation and fireproof board. It can also reduce the burrs generated on the side of the heat insulation and fireproof board caused by the air escaping from the gap between the air-permeable pressure plate and the lower die.

[0019] Among some possible implementation methods, refer to Figures 1 to 3 As shown, the upper surface 12 of the main body 10 has a second transverse airflow groove 121 and a second longitudinal airflow groove 122. The second transverse airflow groove 121 and the second longitudinal airflow groove 122 are connected. The upper surface 12 of the main body 10 is sealed and installed at the output end of the press, so that the second transverse airflow groove 121 and the second longitudinal airflow groove 122 form a second airflow channel. The main body 10 is also provided with a number of through holes 15 to connect the first longitudinal airflow groove 112 and the second longitudinal airflow groove 122. The air hole 13 is connected to the second longitudinal airflow groove 122. During pressing, the air in the lower die passes through the filter screen 14, the first transverse airflow groove 111 / first longitudinal airflow groove 112 and the second transverse airflow groove 121 / second longitudinal airflow groove 122, and finally exits from the air hole 13. In this embodiment, airflow grooves are formed on both the upper and lower surfaces of the main body 10 and the two are connected through the through holes 15 to facilitate the arrangement of the air hole 13 and improve the efficiency of air discharge.

[0020] Among some possible implementation methods, refer to Figure 3 As shown, the air holes 13 are distributed on opposite sides of the main body 10, and the two ends of the second longitudinal airflow groove 122 are respectively connected to the two air holes 13, the purpose of which is to further accelerate the efficiency of air discharge.

[0021] Among some possible implementation methods, refer to Figure 5As shown, the lower surface 11 has several spaced transverse ribs 113, and a first transverse airflow groove 111 is formed between two adjacent transverse ribs 113. The upper end of the transverse ribs 113 can support the filter screen 14, avoiding the problem of uneven thickness of the pressed heat insulation and fire-resistant board caused by the indentation and collapse of the filter screen 14. Air can be discharged from the first transverse airflow groove 111 through the air hole 13.

[0022] Among some possible implementation methods, refer to Figure 5 As shown, the upper two sides of the transverse rib 113 are chamfered 114, which is intended to increase the exhaust effect of the first transverse airflow groove 111.

[0023] Among some possible implementation methods, refer to Figures 1 to 3 As shown, both the upper surface 12 and the lower surface 11 have sealing grooves 16 for installing sealing rings to ensure airtightness between the upper surface 12 and the output end of the press and between the lower surface 11 and the filter screen 14.
