Abstract
The utility model discloses a mold structure for air blowing and cooling felt sound insulation cushion products. The felt product forming machine comprises an upper die, a lower die, an upper die core and a lower die core, wherein the upper die core is arranged at the bottom of the upper die, the lower die core is arranged at the top of the lower die, the upper die core is vertically provided with a plurality of air blowing holes at intervals, and the lower die core is vertically provided with a plurality of air suction holes at intervals. According to the utility model, the air blowing holes of the upper die blow air to the felt (product), and the air suction holes of the lower die suck air in the felt (product), so that the air passes through the product to take away heat in the product, thereby quickly cooling the product and achieving the effect of forming and cooling.
Description
Technical Field
The utility model belongs to the technical field of automobile part molds, and particularly relates to a mold structure for air blowing and cooling felt type sound insulation pad products.
Background
For the mold structure for cooling the products of the felt type mold pressing piece, the prior art usually adopts a cooling water pipe designed in the mold, the mold keeps a lower temperature through circulating cooling water, and the temperature of the product is transferred to the mold through a heat transfer mode, so that the temperature of the product is reduced.
However, the felt type sound insulation cushion product is generally fluffy in material, and only the heat on the surface of the felt can be taken away through a mold structure of circulating cooling water heat transfer, but the heat in the felt is difficult to transfer, so that the temperature of the product is difficult to reduce in a short time.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the prior art and provide a mold structure for air-blowing and cooling felt sound-insulating pad products.
The technical scheme adopted by the utility model is as follows: the utility model provides a felt type sound insulating pad product air blowing refrigerated mould structure, is including the last mould benevolence that is used for felt product make-up machine, lower mould and locates the last mould benevolence of mould bottom, locate the lower mould benevolence at lower mould top, go up the vertical interval of mould benevolence and set up a plurality of gas holes, a plurality of aspirating holes are seted up to the vertical interval of lower mould benevolence.
In a further preferable structure, the air blowing hole is connected with a compressed air storage tank, and the pressure of the compressed air storage tank is 0.3-0.5 MPa.
In a further preferable structure, the air exhaust hole is connected with a vacuum energy storage tank, and the negative pressure of the vacuum energy storage tank is-0.3 to-0.5 MPa.
In a further preferable structure, the diameter of the air blowing hole is 3-6 mm.
In a further preferable structure, the diameter of the air exhaust hole is 3-6 mm.
In a further preferable structure, the distance L1 between two adjacent air blowing holes is 60-100 mm.
In a further preferable structure, the distance L2 between two adjacent extraction holes is 60-100 mm.
When the felt is produced, the upper die descends until the felt product is compressed, the pressure control valve of the air blowing hole of the upper die and the negative pressure control valve of the air suction hole of the lower die are opened at the moment, the air blowing hole of the upper die blows air to the felt (product), the air suction hole of the lower die sucks air in the felt (product), and therefore the air penetrates through the product to take away heat in the product, the product is cooled quickly, and the forming and cooling effects are achieved.

FIG. 1 is a schematic structural diagram of the present invention.
Wherein, 1-upper mold, 2-upper mold core, 3-felt product, 4-lower mold core, 5-lower mold, 6-air blowing hole and 7-air suction hole.
Detailed Description
The utility model will be further described in detail with reference to the following drawings and specific examples, which are not intended to limit the utility model, but are for clear understanding.
As shown in fig. 1, the utility model comprises an upper die 1 and a lower die 5 for a felt product 3 forming machine, an upper die core 2 arranged at the bottom of the upper die 1, and a lower die core 4 arranged at the top of the lower die 5, wherein the upper die core 2 is vertically provided with a plurality of air blowing holes 6 at intervals, and the lower die core 4 is vertically provided with a plurality of air suction holes 7 at intervals.
The air blowing hole 6 is connected with a compressed air storage tank, and the pressure of the compressed air storage tank is 0.3-0.5 MPa.
The air exhaust hole 7 is connected with a vacuum energy storage tank, and the negative pressure of the vacuum energy storage tank is-0.3 to-0.5 MPa.
The diameter of the air blowing hole 6 is 3-6 mm.
The diameter of the air exhaust hole 7 is 3-6 mm.
The distance L1 between two adjacent air blowing holes 6 is 60-100 mm.
The distance L2 between two adjacent extraction holes 7 is 60-100 mm.
During production, an upper die 1 descends until a felt product 3 is compressed, a pressure control valve of an upper die air blowing hole 6 and a negative pressure control valve of a lower die air suction hole 7 are opened, the upper die air blowing hole 6 starts to blow air to the felt (product), the lower die air suction hole 7 starts to extract air in the felt (product), and the air penetrates through the product to take away heat in the product, so that the product is quickly cooled, and the forming and cooling effects are achieved.
Those not described in detail in this specification are within the skill of the art.
