S2. extrusion molding head is molded from any position of closed set slot as starting point clockwise or counterclockwise,
Being arranged at intervals at the rear of extrusion molding head helps a device and injecting head to run simultaneously, the lift when distance injection molding starting point reaches preset distance
It plays extrusion molding head and cuts off modeling liquid, form extrusion molding tail end；
S3. a device is helped to continue to move along, and by the modeling liquid tail end after cutting draw to start position at shape liquid
Bonding.
Preferably, the extrusion molding head provides the pipeline of modeling liquid at least provided with one.
Preferably, the modeling of transfer pipeline described in step S1 liquid supply uses screw rod feed liquid way.
Preferably, preset distance described in step S2 is 0.5-3 centimetres.

A device drawing bonding is helped, it is full not only to ensure that closed set slot can be filled, compactness is more preferable, while being also convenient for automating
Transformation and construction, substantially increase production efficiency, and the head and the tail junction adhesion of door seal can be made integral, ensure that sealing effect
Fruit and airtight quality.
Detailed description of the invention
In order to make the content of the present invention more clearly understood, with reference to the accompanying drawing, the present invention is made further detailed
Thin explanation, in which:
Fig. 1 is the flow chart of the squeeze technology for forming of TPE, TPV door seal of the invention.
Specific embodiment
Referring to Fig. 1, a kind of squeeze technology for forming of TPE, TPV door seal comprising following steps:
S1. extrusion molding head will be conveyed to by transfer pipeline after TPE, TPV hot melt, is injected from extrusion molding head into closed set slot
Closed set slot is filled and forms sealing strip in the outside of closed set slot by TPE and/or TPV the modeling liquid heated in right amount；Institute
Stating the modeling liquid that the TPE heated in right amount and/or TPV modeling liquid refers to that extrusion molding head squeezes out can not only fill completely closed set slot,
The sealing strip of setting shape can also be squeezed out according to the head type chamber of extrusion molding head in the outside of embedding groove as needed simultaneously, it is close
The modeling liquid and external modeling liquid sealed inside embedding groove is integrally formed, and can pass through increasing when larger for the capacity of seal groove a part
The form filling of extrusion molding flow is full；
S2. extrusion molding head is molded from any position of closed set slot as starting point clockwise or counterclockwise,
Being arranged at intervals at the rear of extrusion molding head helps a device and injecting head to run simultaneously, and helps the spacing of a device and extrusion molding head according to extrusion molding work
Skill setting, generally at 1-3 centimetres or so, helping the effect of a device will further be helped through extrusion molding head sealing strip after molding to protect
Demonstrate,prove the position precision of sealing strip；When extrusion molding head is molded starting point around the operation of closed set slot nearly one week of annular, namely in distance
Extrusion molding head is lifted when reaching preset distance and cuts off the modeling liquid at extrusion molding head, forms extrusion molding tail end；
S3. it helps a device to continue to move along, and the modeling liquid tail end after cutting is drawn to substantially cold with start position
Molding modeling liquid is bonded to form closed loop, and the mode for helping a device that clamping can be used in the traction of extrusion molding tail end carries out, namely applies
Certain clamping force pulls extrusion molding tail end Nian Jie to the molded modeling liquid with start position.
The extrusion molding head of the invention provides the liquid feeding pipeline in the pipeline namely extrusion molding head of modeling liquid at least provided with one
Settable one according to actual needs, two, three with first-class, each liquid feeding pipeline can inject the hot melt plastic liquid of different material,
The hot melt plastic liquid of different material extrusion molding head type it is intracavitary be fused into one, hierarchical fusion can also be carried out as needed.
Transfer pipeline described in the step S1 of the present embodiment moulds liquid supply and uses screw rod feed liquid way, or using other pressures
The feed liquid way that power is stayed, as long as can guarantee shot, and can be to confession for the cavity size of different location closed set slot
Liquid measure carries out implementation control.
Preset distance described in the step S2 of the present embodiment is 0.5-3 centimetres namely extrusion molding head is around closed set slot
It extrusion molding nearly one week, cuts off to form extrusion molding tail end from the exit of extrusion molding head by liquid is moulded when apart from 0.5-3 centimetres of start position,
Tail end molten condition not yet at this time, is then closed by helping a device to pull tail end to be bonded formed of shape liquid that have become with start position
Ring.
The squeeze technology for forming of TPE, TPV door seal of the invention is mainly for TPE (thermoplastic elastomer (TPE)), TPV (thermoplasticity
Vulcanized rubber) two kinds of raw materials, but for the technical staff in extrusion molding field, squeeze technology for forming of the invention is not limited in
Both raw materials, it is all that the present invention all can be used in the close or similar raw material of performance and extrusion moulding mode with both raw materials
Technique.
The squeeze technology for forming of TPE, TPV door seal of the invention, using extrusion moulding technique carry out, joint location by
A device drawing bonding is helped, it is full not only to ensure that closed set slot can be filled, compactness is more preferable, while being also convenient for automating
Transformation and construction, substantially increase production efficiency, and the head and the tail junction adhesion of door seal can be made integral, ensure that sealing effect
Fruit and airtight quality.
Above-mentioned specific embodiment is only explained in detail technical solution of the present invention, the present invention not only only office
Be limited to above-described embodiment, it will be understood by those skilled in the art that it is all according to above-mentioned principle and spirit on the basis of the present invention
