A kind of mold for making acoustic board of excellent acoustic board.The mold production process is relatively easy, and production process is brief.
A kind of mold making acoustic board, it is characterized in that being made of bottom plate, side plate, upper plate, installation bolt；Bottom plate is placed on
On shaking platform, three face of bottom plate is open and is in U-shape, and two blocks of side plates are placed in bottom plate two sides and correspond to open-mouth and open bottom plate two sides
Mouth is blocked to form pentahedron, and upper plate is arranged on bottom plate and side plate and is fixed with installation bolt；The bottom plate is in U-shape frid,
It is characterized in that several grooves are arranged in U-lag board bottom portion, the curve of groove is+z2/9=1 y2, wherein 1 < y <, 1,0 < z < 3, if
Raised position between dry groove is equipped with round steel, and on the both sides in bottom plate Yu texturearunaperpendicular direction, there are four blocks altogether, and on block
There is threaded hole；Block makes U-shaped base plate and side plate form a Back Word type groove mold, screw thread on block for limiting two sides side plate
Hole is for fastening upper plate；
The side plate is the recessed convex plate in intermediate projections both sides, and intermediate projections are equipped with side plate round steel；Side plate passes through bottom plate two sides
Block limit；The upper plate is equipped with the trapezoidal dovetail groove in several sections, and upper plate surrounding has threaded hole.
The present invention, which makes acoustic board, can form assembly line, shorten Production Time and cost, the acoustic board made are prefabricated
It is combined afterwards in factory, in-site installation facilitates construction, improves efficiency, realizes shop equipment, EM equipment module, module flowing water
Change；The independently combinable structure of acoustic board reduces installation difficulty, and convenient material transport is easily changed, and realizes installation letter
Dan Hua, it is simple intelligent.Relative to the various non-metal sound barrier of existing market, intensity, rigidity, durability are more preferable, more sharp
Optimize in sound barrier force structure, and cost is low with running cost, also as save a large amount of cost of labor.
And reflected sound is effectively reduced in the multi-angle of acoustic board panel, protrusion, the micropore effectiveness of Felt and inhale every
Space between sound plate further increases sound absorption effect, and the noise that train operation generates is first through acoustic board substantially noise reduction, especially
Suitable for the antinoise such as highway, railway, overhead road of city, urban track traffic barrier and tunnel, underground garage, underground quotient
The noise reduction of the hypogees such as field uses, it is possible to use in urban cells, the municipal administrations such as park.It realizes non-maintaining, improves durability,
Factory prefabricating, noise reduction effect are excellent.

Specific embodiment
Shown in Fig. 1, Fig. 2, Fig. 3, a kind of mold making acoustic board, by bottom plate 1, side plate 2, upper plate 4,3 groups of bolt of installation
At.
Shown in Fig. 2, Fig. 4, Fig. 5, bottom plate 1 is in U-shape and open on three sides, and one of opening upwards are placed on shaking platform
On, two blocks of side plates 2 are placed in 1 two sides of bottom plate (former and later two sides) and block two sides, and the setting of upper plate 4 exists
Bottom plate 1 and side plate 2 are above and fixed by installation bolt 3, and bottom plate 1 is equipped with round steel 6, and round steel 6 is used for the installation of prefabricated acoustic board
Hole.
There are a perpendicular side plate direction, 4 row groove 5 of disposed at equal distance in bottom plate bottom surface, places steel mesh in combination bottom plate when production
Piece, upper plate 4 are covered on above combination bottom plate and reinforced mesh, the block 13 of upper plate 4 and bottom plate 1 are connected using installation bolt 3, directly
A complete sound absorbing plate mold is formed to tightening.In 3 back side panel 2 of fastening bolt because the extruding of upper and lower two mold is fixed.Most
After-pouring super high strength concrete, vibrates, and forms, maintenance, demoulding.
Bottom plate 1 is the support mode for making acoustic board, the U-board that bottom plate 1 is made of lower plate, left plate, right panel.Bottom plate 1 is set
There are 4 row grooves 5, groove 5 is parallel with the chimb 9 of U-type groove, 4 row groove, 5 disposed at equal distance, groove 5(perpendicular side plate direction, equidistant
From arrangement), 5 curvilinear figure of groove is y2/a2+z2/c2=1, wherein a=1, and c=3,1,0 < z < 3 of -1 < y <, groove is for making
Make acoustic board surface bulge, reduces the reflection of sound absorption plate face.8 position of protrusion of bottom plate 1 is arranged in round steel 6, and round steel 6 is for prefabricated
The mounting hole for the plate face that absorbs sound.There are four blocks 7 altogether with the both sides in texturearunaperpendicular direction on bottom plate 1, and block 7 is equipped with screw thread
Hole；Block 7 makes bottom plate 1 form a complete Back Word type with side plate 2 and combines bottom plate, spiral shell on block for limiting two sides side plate 2
Pit is for fastening upper plate 4.
