Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary intended for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 6, a mold for suppressing a sound panel according to an embodiment of the present invention includes a mold frame 1, a bottom plate 2, and a bottom frame 3; the mould frame 1 can be arranged in a vibrating way; the bottom plate 2 is arranged at the bottom of the mold frame 1, and a plurality of water drainage holes 21 are formed on the bottom plate 2; the bottom frame 3 is arranged in a vibrating way, the bottom frame 3 is arranged at the bottom of the mould frame 1 or the bottom of the bottom plate 2, and a plurality of sharp pins 31 which are inserted into the drainage holes 21 and protrude out of the bottom plate 2 are arranged on the bottom frame 3.

When the sound screen panel 10 is manufactured, after the bottom plate 2 and the bottom frame 3 are installed, partial materials such as concrete materials can be added into the mold frame 1, the mold frame 1 vibrates and the bottom frame 3 vibrates to compact the concrete materials to form the panel 101 of the sound screen panel 10, then the compacted panel 101 can be pressed, then sound absorption materials such as sound absorption cotton are placed into the mold frame 1, the sound absorption cotton is close to the end part of the sharp pin 31, the end part of the sharp pin 31 is pointed, the end part of the sharp pin 31 is inserted into the sound absorption cotton after the sound absorption cotton is placed, then the concrete materials are added into the mold frame 1 to cover the sound absorption cotton, and finally the mold frame 1 vibrates and the bottom frame 3 vibrates to compact the concrete materials to form the back layer 102. After the demolding is finished, the sharp pin 31 is pulled out of the sound absorption cotton, and the sound absorption hole 103 is formed in the position corresponding to the sharp pin 31, so that the sound absorption hole 103 of the manufactured sound screen plate 10 is communicated with the sound absorption cotton, external sound can enter the sound absorption cotton through the sound absorption hole 103, and the sound absorption effect is good.

Optionally, the acoustic screen pressing mold may further include a filter screen 4, the filter screen 4 is provided with a plurality of filter holes 41, the filter holes 41 correspond to the drain holes 21 one by one, and the filter screen 4 is located between the bottom plate 2 and the mold frame 1. After the compaction, when the concrete is pressed, the moisture in the concrete can enter the drain hole 21 from the filtering hole 41, and finally the moisture is discharged from the bottom frame 3, so that the density after the pressing is high, and meanwhile, the panel 101 can be formed more quickly after the moisture is extruded, and the efficiency is further improved. The filter holes 41 in this example have a small diameter, allowing only water to pass through, and the concrete cannot pass through the filter holes 41.

As shown in fig. 4, in this example, each of the pins 31 includes a mounting portion 311, a forming portion 312, and a tapered portion 313, the mounting portion 311 is mounted on the bottom frame 3, one end of the forming portion 312 is connected to the mounting portion 311, the tapered portion 313 is connected to the other end of the forming portion 312, and the tapered portion 313 can be inserted into the sound-absorbing cotton. The toper portion 313 is sharp form, and sound absorbing material is comparatively soft like sound absorbing cotton, and sound absorbing cotton places in toper portion 313 after, and toper portion 313 inserts easily and inhales in the sound cotton, and after the drawing of patterns, toper portion 313 breaks away from sound absorbing cotton, and shaping portion 312 corresponds the position and forms and inhales sound hole 103, ensures that each inhales sound hole 103 and inhales the sound cotton and communicates with each other, and sound absorbing effect is good.

In this example, the forming portion 312 has a truncated cone shape, and the diameter of the forming portion 312 gradually increases from the portion closer to the tapered portion 313 to the portion farther from the tapered portion 313. That is to say, after the drawing of patterns, the shaping portion 312 corresponds the position and forms and inhales sound hole 103, and shaping portion 312 is the round platform shape and makes and inhale sound hole 103 also correspond and be the round platform shape hole, also be exactly the horn shape hole, and should inhale sound hole 103 and inhale sound cotton to keeping away from to inhale sound cotton direction aperture crescent by being close to, make the sound of absorbing the incoming sound can be through inhaling sound hole 103 multiple reflection and get into and inhale in the sound cotton, further improve sound absorbing effect.

In some examples, the diameter of the filter hole 41 is larger than the maximum diameter of the molding part 312, so that moisture in the concrete may flow into the drain hole 21 through a gap formed between the filter hole 41 and the molding part 312 and finally flow out of the bottom frame 3.

As shown in fig. 2 and 3, in this example, the vibration motor 11 is disposed at a side portion of the mold frame 1, two mounting plates may extend from two sides of the mold frame 1, two vibration motors 11 may be disposed, and two vibration motors 11 are respectively mounted on one mounting plate. The vibrator 32 is arranged at the side of the bottom frame 3, one vibrator 32 is arranged at one side of the bottom frame 3, and the other vibrator 32 is arranged at the other side of the bottom frame 3, wherein the vibrator 32 can be a pneumatic gear type vibrator. In this example, guide posts 12 are provided on the bottom of the mold frame 1, and guide holes 5 into which the guide posts 12 are inserted are provided on the bottom plate 2 and the bottom frame 3. Wherein, the end of the guide post 12 is in an inverted circular truncated cone shape, that is, the end of the guide post 12 has an arc-shaped guide surface, so that the guide post 12 is more convenient to insert into the guide hole 5.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
