Technical field

The present invention relates to a kind of molding die of damping material and its application methods.

Background technique

With the raising of people's work and life quality, in environment antidetonation, vibration damping, noise reduction requirement also increasingly Height, high-damping structural material are the largely effective means to solve the above problems, and existing high-damping structural material is generally by sticking bullet Property different polymer material layered combination, sandwich structure or other layered arrangement structures are formed, to improve the damping of material Property.Such as utilize the composite construction of three layers of viscoelasticity polymer damping material and steel plate composition, metal mesh sandwich composite damping Material etc., the flexible structure in lamellar composite damping material is variable, and the property of each layer can be different, can also be added between each layer The metal plate layers such as plate, net are to improve the damping capacity of composite material.Since structure is complicated for lamellar composite damping material, while It to be also heating and curing in preparation process, how guarantee that the thickness of layers of material reaches design requirement, gold in cured heating process Belonging to expanded metals not being subjected to displacement all is considered the problems of before material preparation, the preparation side of current this lamellar composite damping material Method is: being to be put metal mesh in a mold, then Macromolecular pouring liquid is cast in die cavity using integrated mould, solidifies.Gold Belong to net to deviate frequent occurrence, and the thickness of each layer Macromolecular pouring liquid is not also accurate, is unfavorable for production and scientific research.

Summary of the invention

The present invention is to solve existing each layers of the mold for preparing lamellar composite damping material, and not accurate, metal Netease occurs The technical issues of displacement, and the molding die and its application method of a kind of composite damping material are provided.

The molding die of composite damping material of the invention includes lower mold, middle layer mold, upper mold and locking dress It sets；

One bottom cavity is wherein set in lower mold, one lower bay, bottom cavity position are set in the upper surface of lower mold In in the region of lower bay covering, the lower bay of upper surface setting positions and fixed for metal mesh；In lower mold Lower layer's location hole is arranged in edge；Bottom cavity is blinded；

One lumen is set in mold in middle level, and the position of lumen and the position of bottom cavity are corresponding；Mold is upper in middle level Middle layer groove is arranged in surface, and lumen is located in the region of middle layer groove covering；It is fixed that the first middle layer is arranged in the edge of mold in middle level Position hole and the second middle layer location hole；Lumen is through；

Lower layer's location hole is corresponding with the position of the first middle layer location hole；

One epicoele is set in upper mold, and the position of epicoele and the position of lumen are corresponding；On the side of upper mold Upper layer location hole is arranged in edge；Epicoele is through；

Upper layer location hole is corresponding with the position of the second middle layer location hole.

The application method of the molding die of composite damping material of the invention is as follows:

One, metal mesh is placed in the lower bay of upper surface of lower mold, is passed through with the bolt of bolt and nut external member First middle layer location hole of lower layer's location hole and middle layer mold is simultaneously fastened with nut；

Two, metal mesh is placed in the middle layer groove of middle layer mold, passes through upper mold with the bolt of bolt and nut external member Upper layer location hole 3-2 and middle layer mold 2 the second middle layer location hole and fastened with nut；

Three, integrated poured or with different types of potting syrup laminated pouring with Macromolecular pouring liquid, after solidification, obtain compound Damping material.

The application method of the molding die of above-mentioned composite damping material, can also be as follows:

One, metal mesh is placed in the lower bay of upper surface of lower mold, is cast in lower layer with Macromolecular pouring liquid Groove and under it is intracavitary；Lower layer's location hole is passed through with the bolt of bolt and nut external member and the first middle layer location hole of middle layer mold is used in combination Nut fastening；

Two, metal mesh is placed in the middle layer groove in the mold of middle layer, is poured groove 2-2 in middle level with Macromolecular pouring liquid And in lumen；Second middle layer of the upper layer location hole and middle layer mold that pass through upper mold with the bolt of bolt and nut external member positions The fastening of Kong Bingyong nut；

Three, it is cast in Macromolecular pouring liquid upper intracavitary；

Four, after solidifying, composite damping material exemplar is obtained.

The molding die of composite damping material of the invention can flexibly arrange in pairs or groups the potting syrup material of different components, and preparation is complicated Combined composite material.It can be very good for metal mesh to be fixed between two layers of composite material with the groove of each interlayer, do not settle, It does not deviate, position is accurate.The hierarchical design of the molding die of composite damping material of the invention, independent assortment also comply with saving Principle replaces the middle layer mold of different-thickness, can get the composite material exemplar of different specific dimensions specifications, when any a part When burn failure, broken parts are only replaced, reduce the investment of mould development, while also adequately achieving to resource again It utilizes.
