When plastics are hydroscopic plastic, it is necessary to which plastics are dried before injection parison is carried out.
Further, in step s 2, the temperature of mould is adjusted by high temperature heat conductive oil, it is met blowing for step S3
Modeling condition.
Further, in step s3, the low pressure blowing and high pressure blowing including successively carried out.
Further, the flow of low pressure blowing is more than the flow that high pressure is blow molded.
Further, injection machine is horizontal injection press.
Further, the feed mechanism is automatic feed mechanism.
The invention provides a kind of preparation method for exempting from spray car empennage, its advantage is：Blown by using note
Technology mode formed automobile empennage, the automobile tail fin of shaping can be excused from a college course that whole, to exempt from spray painting, surface brightness high and colour-fast, and
Time saving material-saving, improves production efficiency and product qualification rate, while reducing the labor intensity of workman, reduces cost.
Brief description of the drawings
A kind of flow chart for preparation method for exempting from spray car empennage that Fig. 1 provides for the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As shown in figure 1, the invention provides a kind of preparation method for exempting from spray car empennage, comprising the following steps：
S1：Prepare raw material, resin to be formed, auxiliary agent and colouring agent are proportionally added and well mixed formed mixes
Material, then compound is sent to by main frame hopper by feed mechanism；
S2：Parison is injected, plastics melten gel is subjected in the barrel of the injection member of injection machine, through heat passage with high pressure
Mode, which is expelled in mold cavity, turns into parison；
S3：Blowing, parison is attached on plug and moved in blow mold, and being blown by plug to the inside of parison makes
It expands, until the inwall of parison and blow mold fits；
S4：Cooling, pressurize cooling is carried out by parison so that parison is shaped；
S5：The die sinking demoulding, mould die sinking, empennage finished parts are stripped and taken out.
, it is necessary to grasp suitable cool time in above-mentioned steps S4, sufficiently cooling can prevent product deformation and ensure
Presentation quality.In S2, the pressure of injection parison is generally 54~100MPa, preferably 58~98MPa.
By the design of above-mentioned its preparation process, the technology mode formed automobile empennage that can be blown by using note, into
The automobile tail fin of type can be excused from a college course whole, high and colour-fast, and time saving material-saving of exempting from spray painting, surface brightness, improve production efficiency and
Product qualification rate, while reducing the labor intensity of workman, reduces cost.
It is preferred that, in step sl, colouring agent is Masterbatch, according to demand the proportioning of color adjustment Masterbatch and addition
Amount, the selection of Masterbatch can arbitrarily be adjusted according to client for the demand of color, can make pigment in product from Masterbatch
In have in preferably dispersed color masterbatch production process and must carry out micronization processes to pigment, to improve dispersiveness and the coloring of pigment
Power.The carrier of special color masterbatch is identical with the plastics variety of product, with good matching, and granules of pigments can be very after heating melting
It is scattered in well in product plastics.
It is preferred that, in step sl, when plastics are non-hygroscopic plastics, compound is directly subjected to injection parison；When
When plastics are hydroscopic plastic, it is necessary to plastics are dried before injection parison is carried out, in order to avoid occur abscess, splay mark or
The defects such as striped.
It is preferred that, in step s 2, the temperature of mould is adjusted by high temperature heat conductive oil, the blowing for making it meet step S3
Condition, using conduction oil because its heat conductivility is preferable, temperature that can be rapidly to mould is adjusted, and saves temperature change
Time.
Wherein, classified according to international standard, the maximum temperature temperature in use of high temperature heat conductive oil is no more than 320 DEG C, at present
The maximum operation (service) temperature of most high temperature heat conductive oils is 300 DEG C.
It is preferred that, in step s3, including the low pressure blowing and high pressure blowing carried out successively, wherein：Low pressure is blow molded and high
The pressure and time for pressing blowing can arbitrarily be adjusted according to actual service condition.
It is preferred that, the flow of low pressure blowing is more than the flow that high pressure is blow molded, and can be use up using the low pressure blowing of big flow can
Can be in the case of parison be cooled down less with contacting dies, the profile for then using high pressure blowing that preform blowup can be made to form mould.
In the preform blowup stage, blowing pressure effect is to make the close patch mold cavity wall of parison deformation and product is protected
Pressure, cooling.Pressure size influences parison speed of deformation.When pressure is small, product may be prevented to be molded from full, it is also possible to cause
The defect such as product after-contraction is serious.When pressure is excessive, parison speed of deformation can increase, and make the non-turning position of parison, quick patch
Plesiotype cavity wall, makes product more early enter the constraint inflation stage, due to the cooling effect of mould, and parison temperature declines at this, viscosity
Rise, it is difficult to continue to deform；Now turning position, still in deformation stage, continues deformation and makes it have larger blow-up ratio, finally
Cause product Wall-Thickness Difference larger.Rational blowing pressure is thus selected in blowing process, qualified product could be obtained.It is preferred that
Ground, the pressure of low pressure blowing is 0.4~0.6MPa, with contacting dies as far as possible in the case of parison is cooled down less；High pressure blowing
Pressure is 0.8~1.2MPa, makes the profile of preform blowup formation mould.
It is preferred that, injection machine is horizontal injection press, wherein, horizontal injection press is compared to vertical injection molding machine, horizontal injection press
Easily maintain, repair, expect clearly and change quick and convenient.
It is preferred that, the feed mechanism is automatic feed mechanism.
Described above, only presently preferred embodiments of the present invention is not intended to limit the invention, every skill according to the present invention
Any trickle amendment, equivalent substitution and improvement that art is substantially made to above example, should be included in technical solution of the present invention
Protection domain within.
