The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 to 5, a core-pulling acoustic panel mold according to an embodiment of the present invention includes a mold frame 1, a bottom plate 3, and a bottom frame 4; the die frame 1 can be arranged in a vibrating way, and a core pulling hole 11 for inserting the core rod 2 is formed at the side part of the die frame 1; the bottom plate 3 is arranged at the bottom of the mold frame 1, and a plurality of insertion holes 31 are formed in the bottom plate 3; the bottom frame 4 can be arranged in a vibration mode, the bottom frame 4 is arranged at the bottom of the mould frame 1 or the bottom of the bottom plate 3, and a plurality of inserting pins 41 inserted into the inserting holes 31 are arranged on the bottom frame 4.
When the sound screen panel 10 is manufactured, the bottom plate 3 and the bottom frame 4 are sequentially installed, then a part of materials such as concrete materials are added into the mold frame 1, the mold frame 1 and the bottom frame 4 compact the part of materials to form the panel 101 of the sound screen panel 10, then the core rod 2 is inserted into the core drawing hole 11, the bottom of the core rod 2 abuts against the end portion of the bolt 41, then the concrete materials are added into the mold frame 1, the mold frame 1 and the bottom frame 4 continue to vibrate to compact the concrete materials to form the back layer 102, after maintenance is completed, the core rod 2 can be drawn out from the core drawing hole 11, the bottom plate 3 and the bottom frame 4 are detached, at the moment, a cavity 103 is formed in the sound screen panel 10, the cavity 103 is communicated with a sound absorption hole 104 formed by the bolts 41, sound absorption materials such as sound absorption cotton can be placed into the cavity 103, the sound absorption cotton is communicated with the outside through the sound absorption hole 104, and the sound absorption effect is improved. When the sound screen 10 is manufactured, the front panel 101 and the back panel 102 are compacted by concrete through the mold frame 1 and the bottom frame 4, so that the manufactured sound screen 10 has strong integral uniformity.
By providing the bottom plate 3, when the bottom frame 4 is detached, the weight of the sound screen panel 10 is supported on the bottom plate 3, so that the latch 41 of the bottom frame 4 is conveniently separated from the sound screen panel 10, the panel 101 of the sound screen panel 10 is not damaged by demolding, and the flatness of the panel 101 of the sound screen panel 10 is maintained.
Optionally, the core pulling hole 11 includes at least two core pulling hole groups arranged side by side, as shown in fig. 1 and fig. 2, in this example, the core pulling hole 11 includes a first core pulling hole group 11a and a second core pulling hole group 11b arranged side by side with the first core pulling hole group 11 a. Wherein, every group loose core hole group includes first loose core hole 111 and second loose core hole 112, the area of first loose core hole 111 is greater than the area of second loose core hole 112, because core rod 2 inserts behind the loose core hole 11, core rod 2 laminating loose core hole 11, that is to say, the area that core rod 2 inserted first loose core hole 111 place is greater than the area that core rod 2 inserted second loose core hole 112 place, make 2 cross-sections of core rod can be isosceles trapezoid, right trapezoid or other similar shapes, so that core rod 2 forms the inclined plane 21 that is convenient for break away from framed 1, when making the preliminary shaping of sound screen panel 10, when core rod 2 breaks away from sound screen panel 10, be convenient for take out core rod 2.
In some examples, each of the pins 41 includes a mounting portion 411, an insertion portion 412, and a forming portion 413, the mounting portion 411 is mounted on the bottom frame 4, the insertion portion 412 is inserted into the bottom plate 3, and the forming portion 413 protrudes from the bottom plate 3, and when mounted, the mounting portion 411 is disposed on the bottom frame 4 and the insertion portion 412 is inserted into the bottom plate 3 such that the forming portion 413 protrudes from the bottom plate 3, so that the sound absorbing hole 104 is formed in the sound panel 10 when the sound panel 10 is manufactured.
Further, the terminal surface of shaping portion 413 is the plane state, the highly uniform of each bolt 41, after inserting core rod 2 into coring hole 11, because the highly uniform of each bolt 41, the terminal surface of each shaping portion 413 is the plane state, make the terminal surface of each bolt 41 shaping portion 413 support and lean on the bottom of core rod 2, pour into in the framed 1 and mix the earth material after, this material can not exist and between the terminal surface of shaping portion 413 and the core rod 2, make the sound absorbing hole 104 of the sound screen board 10 who makes all communicate with each other with cavity 103, thereby make put into the sound absorbing cotton after, the sound absorbing cotton is through the sound absorbing hole 104 direct with external intercommunication, be convenient for inhale the sound. The mandrel bar 2 may be made of a concrete material or a metal material, such as a steel material, so that the weight of the mandrel bar 2 is large, and the mandrel bar 2 can be closely attached to the end surface of the forming portion 413 when the mold frame 1 and the bottom frame 4 vibrate.
In this example, the forming portion 413 is a circular truncated cone, the forming portion 413 protrudes from the bottom plate 3, when pouring, the concrete material covers the forming portion 413, when demolding, the forming portion 413 corresponds to a position to form the sound absorption hole 104, because the forming portion 413 is a circular truncated cone, the sound absorption hole 104 is also a circular truncated cone, namely, the aperture of the end of the sound absorption hole 104 close to the outside is larger than the aperture of the end of the sound absorption hole 104 far away from the outside, so that more noise can be absorbed conveniently, and the sound absorption effect is better.
In some examples, the core pulling acoustic screen mold further comprises a sealing gasket 5, the sealing gasket 5 is located between the bottom plate 3 and the mold frame 1, the sealing gasket 5 forms a through hole 51 for the plug pin 41 to penetrate through, the aperture of the through hole 51 is slightly smaller than that of the insertion portion 412, when the plug pin 41 is inserted into the through hole 51 of the sealing gasket 5, the plug pin 41 and the sealing gasket 5 are in a substantially interference fit, so that water components in the concrete material are effectively prevented from leaking out of the bottom plate 3, and the sealing performance is excellent.
As shown in fig. 2, in this example, the vibration motor 12 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 12 may be disposed, and two vibration motors 12 are respectively mounted on one mounting plate. The vibrator 42 is arranged at the side of the bottom frame 4, one vibrator 42 is arranged at one side of the bottom frame 4, and the other vibrator 42 is arranged at the other side of the bottom frame 4, wherein the vibrator 42 can be a pneumatic gear type vibrator.
In this example, the guide posts 13 are provided on the bottom of the mold frame 1, and the guide holes 6 into which the guide posts 13 are inserted are provided on the bottom plate 3 and the bottom frame 4. Wherein, the end of the guide post 13 is in an inverted circular truncated cone shape, that is, the end of the guide post 13 has an arc-shaped guide surface, so that the guide post 13 is more convenient to insert into the guide hole 6.
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.
