Abstract
The utility model discloses a die for manufacturing an automobile interior trim part. At present, a die for compression molding is produced by billet die casing or machining of an aluminum alloy material; and a lower die is an inseparable whole body and has the defects of high requirement on the machining precision of the surface, high cost and long manufacturing time; and in addition, the die is a solid and is great in heat consumption during work. The die comprises an upper die and a lower die matched with the upper die and is characterized in that the lower die comprises an outer frame and a die cavity layer attached to the outer frame; an inner cavity of the outer frame is a cavity and is formed by welding a metal plate; and a heat conductor is arranged in the die cavity layer. The die is formed by combining the outer frame with the die cavity layer and is simple and convenient in processing and short in manufacturing time; no requirement of precision machining on the surface of the die cavity layer is required, and thus the processing cost is low and the heat loss is low; and a heating water pipe can be maintained and replaced conveniently, and thus the service life of the die is prolonged.
Description
Technical field
The utility model relates to the mould that a kind of compression molding is used, especially a kind of mould of making automotive upholstery.
Background technology
The mould that compression molding is at present used adopts aluminum alloy materials to form through base substrate die casting or machined, and it comprises patrix and the counterdie that matches with patrix, and counterdie is inseparable integral body; High to its surperficial requirement on machining accuracy, difficulty is big, and cost is high; Operation is many and complicated, and Production Time is long; In addition, mould is an entity, and material usage is big, and the thermal losses when work is big.In addition, when the heating pipe in the mould is broken,, change or keep in repair very difficulty, generally all mould is scrapped, influenced the service life of mould because the heating pipe is embedded in the mould.
The utility model content
The utility model technical problem to be solved is the defective that overcomes above-mentioned prior art, and a kind of mould of making automotive upholstery is provided, and its cost is low, processes easyly, and Production Time is short, and thermal losses is little, no requirement on machining accuracy and long service life.
The technical scheme that the utility model adopted is: a kind of mould of making automotive upholstery; Form by patrix and associated counterdie; It is characterized in that described counterdie comprises housing and tightly is attached to the die cavity layer on housing top; The inner chamber of housing is a cavity, is formed by the metallic plate welding, and the die cavity layer is built-in with heat carrier.The die cavity layer adopts cast polyurethane to form, and settles heat carrier before the cast in advance.Inner chamber is the bigger material usage of saving housing of the housing of cavity, has reduced cost, has reduced heat loss; Because the counterdie of mould is that housing and die cavity layer combine, to process easyly, Production Time lacks; The used material of die cavity layer is polyurethane, and the die cavity laminar surface does not have the requirement of precision processing, under the mechanical performance of guaranteeing mould and heat-conductive characteristic, has reduced processing cost; Because heat carrier is in die cavity, thermal losses is little.
Described a kind of mould of making automotive upholstery is provided with the heating pipe in the cavity, the heating pipe is close on the housing inwall that is positioned at die cavity layer below.Because the heating pipe is positioned at cavity, can carry out heating pipe's maintenance or replacing easily, has prolonged the service life of mould.Described a kind of mould of making automotive upholstery, metallic plate is an iron plate; Heat carrier is an aluminium sheet, and its cross section is continuous polyline shaped.Described a kind of mould of making automotive upholstery, the thickness of heat carrier is the 8-12 millimeter.
The counterdie of the utility model is combined by housing and die cavity layer, processes easyly, and Production Time is short; The die cavity laminar surface does not have the requirement of precision processing; Under the mechanical performance of guaranteeing mould and heat-conductive characteristic, processing cost is low, and thermal losses is little; Can carry out heating pipe's maintenance or replacing easily, prolong the service life of mould.The utility model also can be used for making the various products that utilize compression molding: below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of existing mold.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 2; A kind of mould of making automotive upholstery is made up of patrix 1 and associated counterdie, and counterdie comprises housing 2 and tightly is attached to the die cavity layer 3 on housing 2 tops; Housing 2 is welded by iron plate; Die cavity layer 3 adopts the moulding of liquid polyurethane method for filling, and the heat carrier 4 that is continuous polyline shaped is arranged in the die cavity layer 3, and heat carrier 4 is 10 millimeters aluminium sheet for thickness.The inner chamber of housing 2 is a cavity 5, is provided with heating pipe 6 in the cavity 5, and heating pipe 6 is close on housing 2 inwalls that are positioned at die cavity layer 3 below.The die cavity type can adopt prefabricated model cast, also can pour into base substrate earlier and form through machined then, settles heat carrier before the cast in advance.According to the needs of actual product, the shape on patrix bottom and counterdie top has multiple variation, and patrix bottom and product top match, and counterdie top and product bottom match.
Claims (4)
