Art, the technique be it is a kind of by fabric and middle part substrate injection step straight forming a kind of technology, compared to traditional glue spraying
Cover and method, back of the body note technique are the processes that a kind of melt body combines, product environmental protection, manufacturing process is few, adhesive property is excellent, the shaping
Technology has broad application prospects.And for the middle part fabric with sewing thread, during injection forming is carried on the back, it can sew
Seep through phenomenon occurs at the pin hole of line, and then influences the presentation quality of product.
The content of the invention
In view of the above problems, the object of the present invention is to provide back of the body injection forming side in the middle part of a kind of automobile door plate with sewing thread
Method, to solve during injection forming is carried on the back, there are the problem of seep through at the pin hole of sewing thread.
Back of the body injection forming method in the middle part of automobile door plate provided by the invention with sewing thread, including：
Step S100：The back side of the sewing thread of middle part fabric in 10 ~ 15 seconds was warming up to 80 ~ 85 by infrared heating mode
DEG C, and keep the temperature 1 ~ 1.5 minute；
Step S110：By heat-sealing machine by the back of the body of the sewing thread of the TPE plastic films heat seal of 0.1 ~ 0.15mm thickness to middle part fabric
Face；Wherein, the heat-seal temperature of heat-sealing machine is 180 ~ 210 DEG C, and the heat-sealing speeds of heat-sealing machine are 30 ~ 40mm/s；
Step S120：The middle part fabric that heat seal there are TPE plastic films is suspended in the cavity of injection mold and carries out injection molding；
Wherein, injection temperature is 200 ~ 210 DEG C, and injection pressure is 50 ~ 60MPa, and the temperature of injection mold is 15 ~ 20 DEG C.
Compared with prior art, beneficial effects of the present invention are：
1st, by the back side heat seal TPE plastic films of the sewing thread in middle part fabric, seam can be flowed directly into avoid injection melt
Thread line pin hole and seep through；
2nd, before by TPE plastic films heat seal to the back side of the sewing thread of middle part fabric, infrared heating is carried out to middle part fabric
Processing, can be effectively ensured the heat sealing strength of TPE plastic films；
3rd, TPE is ethylene octane copolymer material, has good blending with the polypropylene material of molded plastic substrate, meanwhile, should
Elastomeric material has good heat seal performance with fabric；
4th, method is easy, and selection and implementation are of low cost, and product appearance quality is good.
In order to realize above-mentioned and related purpose, one or more aspects of the invention include the spy that will be explained in below
Sign.Some illustrative aspects of the present invention are described in detail in following explanation and attached drawing.However, these aspect instructions are only
It is some modes in the various modes for can be used the principle of the present invention.In addition, it is contemplated that including all these aspects with
And their equivalent.
Brief description of the drawings
By reference to the explanation below in conjunction with attached drawing, and with the present invention is more fully understood, of the invention is other
Purpose and result will be more apparent and should be readily appreciated that.In the accompanying drawings：
Fig. 1 is the flow diagram of back of the body injection forming method in the middle part of the automobile door plate with sewing thread according to the present invention.
Embodiment
In the following description, for purposes of illustration, in order to provide the comprehensive understanding to one or more embodiments, explain
Many details are stated.It may be evident, however, that it can also realize these embodiments in the case of these no details.
In other examples, for the ease of the one or more embodiments of description, known structure and equipment are shown in block form an.
Fig. 1 shows the flow of back of the body injection forming method in the middle part of the automobile door plate with sewing thread according to the present invention.
As shown in Figure 1, back of the body injection forming method in the middle part of the automobile door plate provided by the invention with sewing thread, including：
Step S100：The back side of the sewing thread of middle part fabric in 10 ~ 15 seconds was warming up to 80 ~ 85 by infrared heating mode
DEG C, and keep the temperature 1 ~ 1.5 minute.
Preferably, by infra red heating device by the back side of the sewing thread of middle part fabric after 15 seconds 85 DEG C of heat temperature raisings,
Insulation 1 minute.
