The invention relates to a multi-layer extrusion die. The multi-layer extrusion die is characterized in that the extrusion die comprises a die body, a flow splitting plate, a flow splitting cone, a flow splitting support, a sizing sleeve, a bush die and a mandrel. The mandrel penetrates through the bush die to be arranged inside the die body. One end of the mandrel is connected with the flow splitting cone, and the other end of the mandrel is connected with the sizing sleeve. The flow splitting cone is arranged on the flow splitting cone support. The flow splitting plate is arranged at the end of the die body. A plurality of layers of extrusion plates are arranged on the mandrel. According to the technical scheme, the sizing sleeve is arranged for better guaranteeing the product precision and extruded product quality, and the service life of the die is long; and the flow splitting plate is arranged for guaranteeing the stability of products in the forming process, multi-layer extrusion is achieved, the working efficiency is improved, and large-scale application and popularization are facilitated.
Description
Technical field
The present invention relates to a kind of mould, and in particular to a kind of Multi layer extrusion mould, belongs to mold component technical field.
Background technology
Mould, in commercial production in order to be molded, to be blow molded, to extrude, die casting or the method such as forging forming, smelting, punching press obtain
The various moulds of required product and instrument.In brief, mould is used to the instrument of formed article, and this instrument is by various zero
Part is constituted, and different moulds is made up of different parts.It mainly realizes thing by the change of institute's moulding material physical state
The processing of product profile.Blank is made to become the instrument of the product having given shape and size under external force.Be widely used in punching,
The compression moulding of die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and the product such as engineering plastics, rubber, pottery or note
In the forming moulded.
In industrial processes, often extrusion die to be used carries out the extruding production of section bar, the shape of section bar, size
Limited and molding by extruding grinding tool Deng all, wherein, by the nib molding of lower mould, the endoporus of section bar is by mould for the profile of section bar
The upper mold core head molding of tool.But there is problem in extrusion die of the prior art：Working life is relatively low, and scrappage is relatively
Height, complex structure, precision is low, the complex manufacturing of processing this extrusion die of formation, and the production cycle is longer, and production cost is higher
Etc. defect, and extrusion die is mostly the extruding of monolayer, and therefore, a kind of new scheme of exigence solves this technology and asks
Topic.
Content of the invention
The present invention is exactly directed to technical problem present in prior art, provides a kind of Multi layer extrusion mould, this device is whole
Body smart structural design, compact, cost is relatively low, and this technical scheme can preferably ensure the precision of product it is achieved that many
Layer extruding, high working efficiency, with short production cycle, reduce entreprise cost.
To achieve these goals, technical scheme is as follows, and a kind of Multi layer extrusion mould is it is characterised in that institute
State extrusion die and include die ontology, flow distribution plate, spreader, shunting support, calibration sleeve, mouth mould and mandrel, described mandrel is worn
Cross mouth mould to be arranged in die ontology, one end of described mandrel connects spreader, and the other end connects calibration sleeve, and described spreader sets
Put on spreader support, described flow distribution plate is arranged on the end of die ontology, described mandrel is provided with Multi layer extrusion plate, real
Existing Multi layer extrusion, wherein Multi layer extrusion plate is at least two-layer.
As a modification of the present invention, described extrusion die also includes suction nozzle, and described suction nozzle is arranged on mould originally
The side of body.
As a modification of the present invention, described extrusion die also includes connecting plate, and described connecting plate is arranged on mould originally
The both sides of body.
With respect to prior art, advantages of the present invention is as follows：1）Overall construction design of the present invention is ingenious, compact conformation, practicality
By force；2）It is provided with calibration sleeve in this technical scheme, can preferably ensure the precision of product it is ensured that extruded product quality, mould
Last a long time；3）This technical scheme is provided with flow distribution plate it is ensured that stability during formed product, high working efficiency, institute
State and Multi layer extrusion plate is provided with mandrel, realize Multi layer extrusion, be easy to large-scale popularization and application.
