Abstract
The utility model provides an extrusion die, it includes preceding template and back template, back template assembly mold core, back template side position be provided with a feed port, the front portion of back template is provided with symmetrical two feed chutes, preceding template settings have a feeding bush, preceding template and back template are through location pin positioning to the template is slided around can only following with the back template before making, be provided with the inlet port on the shop bolt, this inlet port is connected to the venthole on the mold core through the back template, preceding template with the back template carry out fixed connection through the screw, it has simple structure, and processing is convenient, two mutual noninterferences of extruder when extruding, and the adjustability is good, and the rejection rate is low, characteristics such as production efficiency height.
Description
Technical field
The utility model relates to the extrusion die of a kind of new construction, refer more particularly to a kind of double compound extruded rubber system
The mould of product, belongs to technical field of mold.
Background technology
Existing pair of compounded rubber sealing strip product, when carrying out extrusion sulfuration and producing, twin screw to be used is double compound
Extruder, but this type of machine is expensive, and also the sizing material physical property difference of this type of rubber composite product is relatively big, for double compound
The requirement of extruder is the highest, controls inconvenience during production, and production efficiency is low.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art to exist, and provides a kind of simple in construction, and processing makes
With convenient, reliable, by the transformation to existing mold, double compound extruded can be produced with two single single screw extrusion machines and produce
Product, less input, controlled convenience during production, the extrusion die that production efficiency is high.
In order to solve the technical problem of above-mentioned existence, this utility model mainly uses following technical proposals: one is extruded
Mould, it includes front template and rear pattern plate, and described rear pattern plate assembling mold cores, described rear pattern plate lateral location is provided with
One charging hole, the front portion of rear pattern plate is provided with double feed wells of symmetry, and described front template is provided with charging mouth die, front template
Positioned by shop bolt with rear pattern plate, and make front template and the rear pattern plate can only be along front and back's sliding.
As preferably: be provided with air inlet on described shop bolt, this air inlet is connected to mold cores by rear pattern plate
On venthole；Described front template and rear pattern plate are fixedly connected by screw.
This utility model utilizes existing extrusion die, adds at rear pattern plate lateral location one charging hole of processing and front portion
Double feed wells that work is symmetrical, front template keeps constant, and front and back template alignment pin positions, and is screwed, on alignment pin
Processing passage, the venthole being connected on core.When producing, a kind of sizing material is clamp-oned from behind, and another sizing material is from rear
The side-fed of template, imports mould, and final extrusion molding by feed well, and external compressed air simultaneously, by core
Venthole, enter interiors of products, reach auxiliary sizing purpose.
This utility model has simple in construction, easy to process, and during extrusion, two extruders does not interfere with each other, and adjustability is good, useless
Product rate is low, production efficiency high.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the schematic top plan view of Fig. 1
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.Shown in Fig. 1-2, described in the utility model one
Planting extrusion die, it includes that front template 1 and rear pattern plate 2, described rear pattern plate 2 are assemblied in mold cores, described rear pattern plate 2 side
Position, face is provided with a charging hole 5, and the front portion of rear pattern plate 2 is provided with double feed wells of symmetry, and described front template 1 is provided with
Charging mouth die 6, front template 1 and rear pattern plate 2 are positioned by shop bolt 3, and make front template 1 and the rear pattern plate 2 can only be along front and back sliding
Move.
Shown in figure, described shop bolt 3 being provided with air inlet, this air inlet is connected to mold cores by rear pattern plate
On venthole 4；Described front template 1 and rear pattern plate 2 are fixedly connected by screw 7.
Embodiment: a kind of new construction extrusion die described in the present embodiment, it utilizes single single screw extrusion machine to be used for
Producing double compound extruded product, as it is shown in figure 1, mould includes front template 1 and rear pattern plate 2, rear pattern plate lateral location processes one
Charging hole 5 and double feed wells of anterior processing symmetry, front template keeps constant, is machined with charging mouth die 6, and front and back template uses
Shop bolt 3 positions, it is ensured that upper and lower plates, only along sliding front and back, is processed passage simultaneously on alignment pin, is connected on core
Venthole 4, front and back template is fixed by screw 7.
During use, front and back template is fixed by alignment pin and screw, puts into extruding dies position, a kind of sizing material
Clamp-oning from behind, directly by front template mouth die, another sizing material, from the side-fed of rear pattern plate, imports mould by feed well
Tool, and final extrusion molding, external compressed air simultaneously, by the venthole on core, enter interiors of products, reach auxiliary fixed
The purpose of type.During this, two extruders do not interfere with each other, and can carry out independent technique adjustment, and whole process operation is easy,
Putting into low, production efficiency is high, and steady quality, technique is realisation good.
Described mould includes template before and after employing, rear pattern plate lateral location one charging hole of processing and rear portion processing symmetry
Double feed wells, front template is constant, rear pattern plate assembling mold cores.
On the rear pattern plate of described mould, shop bolt is installed, by alignment pin, reaches the location with front template and couple, and
It is fixed by screw.
Air inlet, and the venthole being connected on core by rear pattern plate it is machined with on the alignment pin of described mould so that it is
Can smooth and easy ventilation.
Described mould operationally can carry out independent technique initialization with the interference-free extruder to two platform independent, to reach
To the purpose that can more preferably realize quality of item.
In description of the present utility model, technical term " on ", D score, "front", "rear", "left", "right", " interior ",
" outward " etc. represent that direction or position relationship are based on direction shown in the drawings or position relationship, are for only for ease of description and understand
