Description
Technical field
The invention belongs to automobile door plate hot pressing coating mould technical fields, in particular to a kind of to form air curtain by air duct slot
Automobile door plate hot pressing coat lower mold.
Background technique
In the prior art for automobile door plate hot pressing cladding mold be divided into upper mold and lower mold, such as application No. is
The utility model of CN201320673756 discloses a kind of for coating the device of auto parts, which includes for solid
Determine the upper mold of auto parts substrate and coat the lower die of skin for fixation, the top surface of the bottom surface of the upper mold and the lower die is phase
The hot pressing face of adaptation, the top surface of the lower die are provided with locating slot, and the outside of the locating slot is provided with sealing ring, the lower die
Top surface be provided with positioning pin.The effect of positioning pin described in the utility model is then led to for carrying out Primary Location to covering
It crosses locating slot and matching positioning is carried out to the sewing thread on covering face, it may further be by carrying out vacuumizing place to sealing ring inside
Reason is accurately positioned the sewing thread on covering face to realize.
In the prior art, several vacuum holes are equipped on the lower mould body of the mold of automobile door plate hot pressing cladding, had
Be additionally provided with before lower mould body with automobile door plate covering knob position shape similar opening, connect for installing with cylinder
Movable mould tire, to realize the cladding to knob position covering, during automobile door plate hot pressing cladding process, first in covering
Reverse side roller coating non-reactive hot melt adhesive, is then fitted in lower mould upper surface for covering front, and lower mold is covered by vacuum suction
Then door-plate skeleton is placed on upper mold, the mobile heating covering of heating plate and skeleton surface, because of non-reactive glue by the front of skin
Activationary temperature is higher, and a large amount of smog is volatilized during heating, these smog under the action of lower mold vacuumizes, from
The trailing edge of lower mold and the automobile door plate covering knob similar approximately circular opening edge of position shape and lower mold
It is adsorbed to covering front, after skeleton and covering pressing, in opening similar with automobile door plate covering knob position shape
Covering front near the trailing edge of adjacent edges and lower mold forms fuzzy offset printing, influences the positive quality of covering,
In order to overcome this defect, the prior art is all these fuzzy offset printings of manual cleaning, not only influences production efficiency, but also clear up
It is not thorough, still the influence positive quality of covering.
In order to solve the problems, such as this, the applicant demonstrates many schemes, takes out wherein using and increasing in the top of upper mold
Wind system takes the smog volatilized during heating away, still, due to the limitation of this body structure of equipment, exhausting system
Draught hood positional distance covering reverse side is higher, cannot rapidly take smog in time away, also has part smog and takes out very in lower mold
Under the action of sky, from lower mold approximately circular opening edge similar with automobile door plate covering knob position shape and lower die
The trailing edge of tool is adsorbed onto covering front, to so influence the positive quality of covering.
The applicant also used the power by reducing heating plate to reduce the activationary temperature to non-reactive hot melt adhesive,
To reduce the volatile quantity of smog, experiments have shown that, the volatile quantity of smog significantly reduces really, and the positive quality of covering is also changed
Kind, still, due to the reduction of temperature of heating plate, the non-reactive hot melt adhesive of covering reverse side roller coating is not activated sufficiently, causes to cover
The partial region of skin reverse side cannot be sufficiently bonded with skeleton, or the phenomenon that coming unglued after being bonded occur, and can not meet automobile door plate
The requirement of hot pressing cladding process.
The applicant in experiments it is found that, at left and right sides of lower mold with automobile door plate covering and the covering in forward position front
Quality volatilizes the influence of a large amount of smog during not being heated, the reason is that having in the left and right sides of lower mold and forward position
There is upward protrusion, these protrusions jack up at the positive edge of covering upwards, and mold passes through the front of vacuum suction covering instantly
When, the shape to raise upward is also formed by the positive edge of covering that the marginate protrusion of these lower dies jacks up upwards, this
A little covering front edge protrusions play the role of blocking smog, make not obscure near these covering front edges protrusions
Offset printing, and the no protrusion of the trailing edge of lower mold and knob position approximately circular opening edge, these do not have edge protuberance
Covering front nearby then produce fuzzy offset printing, thus so influence the positive quality of covering；After this discovery, the application
People increases similar protrusion with knob position approximately circular opening edge in the trailing edge of lower mold, to eliminate fuzzy
Offset printing, still, the left and right sides and forward position of lower mold, which have upward protrusion, to be arranged according to product itself shape need,
The trailing edge and knob position approximately circular opening edge of lower mold are also to be set according to product itself shape need in plane
It sets, although the trailing edge and knob position approximately circular opening edge in lower mold newly increase protrusion and eliminating covering just
The offset printing of face mould paste, but impression is produced in covering front, also affect the positive quality of covering.
Summary of the invention
Problem to be solved by this invention is that overcome the deficiencies in the prior art place and defect, providing both can be to avoid illiteracy
Skin front obscures the generation of offset printing, improves product quality, and one kind that production efficiency can be improved forms air curtain by air duct slot
