Description
Technical field
It is especially a kind of to extrude bore beyond extruder the utility model relates to a kind of extrusion die of rubber
Porous extrusion sebific duct product mould.
Background technology
Existing extrusion class rubber tubular product, is typically limited by existing cross-head size when extrusion, is
Single hole extruded product is carried out by the mouth mold in single hole.It is typically out of question to the not high similar products of order volume, but to ordering
Single amount is accomplished by greatly big mouth mold, and supporting in order to be carried out with existing extruder, thus to carry out new construction to extrusion die
Design and produce.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides one kind in prior art basis
Improved, realize porous using existing small dimension extruder while extruding sebific duct product, put into low, production efficiency height, matter
Amount is stable, the extrusion die of the realisation good rubber of technique.
In order to solve above-mentioned technical problem, the utility model, which is mainly, uses following technical proposals：A kind of rubber
The extrusion die of product, it includes a switching head connected with cross-head, is configured with the switching head by preceding mould
The mold that plate and rear pattern plate are combined, described rear pattern plate is fixed with the porous core rod stretched into forward in front template, and
Described front template and rear pattern plate can coordinate the relatively front and rear sliding of front template and rear pattern plate by positioning finger setting.
As preferred：Described alignment pin is fixedly mounted on before rear pattern plate and can be by the pin that is opened up on front template
Hole is screwed, axially arranged on described alignment pin to have air admission hole, and the air admission hole is connected by the gas channel in rear pattern plate
Pass to the venthole opened up on the porous core rod.
As preferred：Described rear pattern plate is arranged in the horn-like inner chamber set inside switching head, the switching machine
The front portion of head is provided with the inner groovy of embedded front template；The outside wall surface of described switching head is provided with by the sealed water of groove lid
Cold trap.
The utility model utilizes existing extruder specification, in the mouth mold of front template and arranges porous tube chamber,
It is simultaneously corresponding that porous tube core is processed in rear pattern plate, due to extruding the increase of pipe product number, also increase accordingly into glue
Material, once carries out smallization processing to rear pattern plate, removes unnecessary mold materials, facilitates the increase of sizing material amount to enter, and passes through positioning
Pin is combined front and rear template；Due to the increase of hole count, the size of mouth mold can not be normal more than the extruder of existing specification
Install, to process an inner chamber behind existing mouth mold to this for horn-like switching head, so can be carried out more empty
While extrusion.
The utility model has simple in construction, and easy to process, adjustability is good during extrusion, and steady quality, percent defective is low, production
Efficiency high, the features such as technique is realisation good.
Brief description of the drawings
Fig. 1 is Split type structure schematic diagram of the present utility model.
Label in figure is：1. head of transferring, 2. water-cooling grooves, 3. water cooling groove lids, 4. rear pattern plates, 5. air admission holes, 6. determine
Position is sold, 7. core rods, mouth mold before 8..
Embodiment
The utility model is further described below in conjunction with accompanying drawing.Shown in Fig. 1, one kind described in the utility model
The extrusion die of rubber, it includes a switching head 1 connected with cross-head, is configured with the switching head 1
The mold combined by front template 8 and rear pattern plate 4, described rear pattern plate be fixed with stretch into forward it is porous in front template
Core rod 7, and described front template 8 and rear pattern plate 4 positioned by alignment pin 6, and front template and rear pattern plate can be made relatively front and rear
Sliding coordinates.
Shown in figure, alignment pin 6 described in the utility model is fixedly mounted on before rear pattern plate 4 and can be by preceding mould
The pin-and-hole opened up on plate 8 is screwed, axially arranged on described alignment pin 6 to have air admission hole 5, and the air admission hole 5 passes through rear mold
Gas channel in plate 4 is communicated to the venthole opened up on the porous core rod 7.
Rear pattern plate 4 described in the utility model is arranged in the horn-like inner chamber that the inside of switching head 1 is set, the switching
The front portion of head 1 is provided with the inner groovy of embedded front template 8；The outside wall surface of described switching head 1 is provided with close by groove lid 3
The water-cooling groove 2 of envelope.
Embodiment：The utility model utilizes small dimension extruder to be used for a plurality of extruded product, as shown in figure 1, mould includes
Front template 8 and rear pattern plate 4, rear pattern plate are fixed with core rod 7 and alignment pin 6, and front template keeps constant, and front and rear template uses alignment pin
Nail 6 is positioned, it is ensured that upper and lower plates are only along front and rear sliding, while the processing gas inlet hole 5 on alignment pin, front and rear template is fixed by screw,
Whole mould is connected by head 1 of transferring with extruder, is machined with water-cooling groove 2 on switching head, water-cooling groove is carried out close by groove lid 3
Envelope.
The mould is included using front and rear template, and the side position of rear pattern plate two removes unnecessary mould material, and forms a section
