Abstract

The utility model relates to a mould, which is used for compression moulding formation. The mould which is used by the compression moulding formation is formed by the blank body pressure casting or the machine work of aluminum alloy materials at present, a lower mould is an inseparable whole, the requirements of the machining accuracy of the surface of the lower mould is high, the cost is high, and the manufacture time is long. Additionally, the mould is an entity, and the thermal losses are large in the process of operating. The utility model is composed of an upper mould and the lower mould which is matched with the upper mould. The utility model is characterized in that the lower mould comprises an outer frame and a die cavity layer which is tightly attached on the upper part of the outer frame, an inner cavity of the outer frame is a hollow cavity and is formed by welding metal plates, and a heat conductor is arranged in the die cavity layer. The lower mould of the utility model is formed by combining the outer frame and the die cavity layer. The utility model has the advantages of convenient processing, short manufacture time, no accuracy processing requirement of the surface of the die cavity layer, low processing cost and few thermal losses. The maintenance or the replacement of a water heating pipe can be conveniently carried out, and the service life of the mould can be extended.

Description

A kind of novel die
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, to its surperficial requirement on machining accuracy height, difficulty is big, the cost height, 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
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, and a kind of novel die 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 novel die, be made up of 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, formed by the metallic plate welding, 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, 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 novel die 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 novel die, heat-conducting plate are iron plate; Heat carrier is an aluminium sheet, and its cross section is continuous polyline shaped.
Described a kind of novel die, the thickness of heat carrier are the 8-12 millimeter.
Counterdie of the present utility model is combined by housing and die cavity layer, process easy, 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.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the structural representation of existing mold.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 2, a kind of novel die, form by patrix 1 and associated counterdie, 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 by 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.
