Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind for the treatment of process of car trim surface, the technical problem that the present invention solves how to reduce environmental pollution.
Object of the present invention realizes by following technical proposal: a kind for the treatment of process of car trim surface, is characterized in that, comprise the following steps:
A, decoration substrate forming;
The installation of b, decoration base material and diaphragm: decoration base material and diaphragm are all placed in closed cavity, diaphragm to be fixed in closed cavity and closed cavity is divided into upper chamber and lower chambers, and decoration base material is positioned at the bottom chamber below diaphragm;
C, vacuum adsorption molding, comprise the following steps:
C1, upper chamber and lower chambers vacuumized and heats;
C2, lower chambers keep vacuum state, and upper chamber's inflating pressure, makes diaphragm be covered on decoration base material;
D, cooling and shaping: take out the decoration base material after overlay film, normal temperature cools;
E, cutting: unnecessary membrane cutting on the decoration base material after overlay film is removed;
F, inspection: the decoration base material after overlay film is up to the standards, vanning.
In the treatment process on this car trim surface, have employed the technique of vacuum coated, avoid adopting and spray paint or technique that plating etc. easily pollutes environment, reduce the pollution to environment with this; Meanwhile, during decoration surface vacuum adsorption forming, by lower chambers is kept vacuum, upper chamber's inflating pressure, be covered on the surface of decoration with this by diaphragm, this treatment process can be applicable to the product of various Curvature varying, especially can change large product by shaping surface curvature; In addition, decoration base material is alternative large, and decoration base material can be the working of plastics of current any technique, comprises injection moulding, blowing, extrudes, extrudes, mold pressing etc., and pottery, metal, SMC, PHC, glass etc. also can overlay films as the product of base material.
In above-mentioned plastic part surface decoration technology, in described step c1, heating-up temperature is 100 ° ~ 120 °, and the heat time is 25 ~ 45 seconds.Diaphragm heats at a proper temperature can deliquescing, and diaphragm and decoration base material are better fitted.
In above-mentioned plastic part surface decoration technology, in described step c2, the blowing pressure of upper chamber is 20 ~ 30KGF/ ㎡, 25 ~ 35 seconds dwell times.Diaphragm is subject to the blowing pressure, can extend the surface covering decoration base material, and overlay film percentage elongation can reach more than 300%, and shaping rear outward appearance, texture, pattern are indeformable, or is out of shape minimum naked eyes and should not discovers.
In above-mentioned plastic part surface decoration technology, in described steps d, normal temperature cool time is 50 seconds.After normal temperature cools a period of time, the decoration after overlay film completes sizing.
In above-mentioned plastic part surface decoration technology, in described step e, adopt high pressure waterjet to diaphragm unnecessary on the decoration base material after overlay film, hydraulic pressure is 45000psi, and the air pressure of high pressure waterjet is 5.0kg/cm
2.Little decoration product also can carry out hand cut.
In above-mentioned plastic part surface decoration technology, in described step b, decoration base material is placed on bottom chamber by fixing tool.According to substrate product size, make the fixing tool meeting substrate product size.
Compared with prior art, the treatment process on this car trim surface has the following advantages: 1, present treatment technique is sprayed paint or electrophoresis process in implementation process, to this reduce the pollution to environment; 2, present treatment technique can complete the large scale product of profile complexity change; 3, present treatment technique reduces the cost of decoration incrustation.
Accompanying drawing explanation
Fig. 1 is the flow chart of the treatment process on this car trim surface.
Detailed description of the invention
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
As shown in Figure 1, the treatment process on this car trim surface comprises the following steps:
A, decoration substrate forming;
The installation of b, decoration base material and diaphragm: decoration base material and diaphragm are all placed on closed cavity, diaphragm to be fixed in closed cavity and closed cavity is divided into upper chamber and lower chambers, decoration base material is positioned at the bottom chamber below diaphragm and is placed on bottom chamber by fixing tool, between decoration base material and diaphragm, there is gap, and gap is less;
C, vacuum adsorption molding, comprise the following steps:
C1, vacuumizing and heat upper chamber and lower chambers, heating-up temperature is 100 ° ~ 120 °, and the heat time is 25 ~ 45 seconds; C2, lower chambers keep vacuum state, and upper chamber's inflating pressure, makes diaphragm be covered on decoration base material, and the blowing pressure of upper chamber is 20 ~ 30KGF/ ㎡, 25 ~ 35 seconds dwell times;
D, cooling and shaping: take out the decoration base material after overlay film, normal temperature cools, and cool time is 50 seconds;
E, cutting: adopt high pressure waterjet to diaphragm unnecessary on the decoration base material after overlay film, hydraulic pressure is 45000psi, and the air pressure of high pressure waterjet is 5.0kg/cm
2;
F, inspection: the decoration base material after overlay film is up to the standards, vanning.
In present treatment technique, the principle of step c vacuum adsorption molding is: because between decoration base material and diaphragm, gap is less, when vacuumizing upper and lower chamber, the air pressure in gap is less than the air pressure outside gap, utilizes air-flow and air pressure, Dicoration base material is tentatively adsorbed on diaphragm,, upper and lower chamber is heated meanwhile, make diaphragm deliquescing, again by making diaphragm extend and be covered on decoration base material completely at upper chamber's inflating pressure, complete the decoration of decoration substrate surface with this.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ the terms such as decoration base material, diaphragm, closed cavity, upper chamber, lower chambers, fixing tool herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
