Description
Technical field
A kind of mould is the utility model is related to, more particularly to a kind of injection moulding of zero polyurathamc coating composite plate
Mould.
Background technology
At present, on the inner-decoration components such as cover plate of spare tire of automobile, board putting things and sunshading board, PHC materials are widely used.
PHC materials are sandwich, and using core as substrate, upper and lower composite cover, then surface recombination decorative layer form, have light weight,
The features such as intensity is high.Therefore, people want by the materials application automobile exterior part（Such as automobile engine cover, top cover）On,
But in actual use, the direct class-A surfaces for applying PHC materials not reach automobile exterior trimming parts also, waterproof, intensity, ageing-resistant etc.
It is required that developer on the basis of PHC materials, coats a kind of polyurethane of zero foaming（PU）Coating,（Only in the appearance of part
Face applies polyurethane coating, and inner surface does not need coating）, the requirements of automobile exterior trimming parts can be reached, therefore, in industrialized production
When, it is necessary to develop a kind of zero polyurathamc coating injection mould.
The content of the invention
The purpose of this utility model is to overcome the shortcomings that having existed, there is provided one kind is used to process zero polyurathamc
The injecting molding die of coating composite plate.
The technical scheme of the polyurathamc injecting molding die of the utility model zero is：It is characterized in that including cope plate and
Lower template, die cavity is set between cope plate and lower template, PHC sheet materials are placed in die cavity, is respectively provided with and adds in cope plate and lower template
Pipe line, the external die heater of pipeline is heated, is set in cope plate and vacuumizes suction hole, vacuumize the external evacuator in suction hole,
The side of lower template sets injection port, and the opposite side of lower template sets flash area, adsorbing mechanism, adsorption machine are set in lower template
PHC sheet materials are fixed in lower template by structure.
The utility model discloses a kind of reaction type polyurethane injecting molding die, during production, whole secondary mould is arranged on mould
In press, cope plate is first in die opening state with lower template, heats pipeline pre-temperature, then PHC sheet materials are put into the die cavity of lower template
In, and adsorbed and fixed by adsorbing mechanism, then upper and lower template matched moulds, polyurethane（PU）Material starts to inject at injection port, together
When, vacuumize suction hole and suction produced by external evacuator, by the polyurethane material of injection from sprue to vacuumizing suction
Being drawn at hole, polyurethane material flows through from the upper surface of PHC sheet materials, flows to flash area always, forms one layer of polyurethane coating, just as
That to coat one layer of polyurethane coating in the upper surface of PHC sheet materials the same, when vacuumize be stopped after, pressurize sizing, formed poly-
Urethane coating composite plate, last upper and lower template die sinking, is taken out the composite plate of shaping by manually or mechanically hand.
Zero polyurathamc injecting molding die of the present utility model, the concrete technical scheme of described adsorbing mechanism have compared with
It is a variety of, such as vacuumizing and adsorbing hole, another external evacuator of vacuumizing and adsorbing hole, by evacuator are set in lower template
Generation vacuumizes suction and is fixed PHC sheet materials by vacuumizing and adsorbing hole.Or sucker is set in lower template, sucker with
PHC sheet materials are in contact to adsorb and fixed.The external injection head of described injection port, is easy to polyurethane（PU）Material injection.Described
Lower template periphery sets seal groove, sets sealing strip in seal groove, is in contact with cope plate during sealing strip matched moulds, makes the close of die cavity
Envelope property is good, vacuumizes suction efficiency high.Upper thermal insulation board and upper plate are set on described cope plate.Set under described lower template
Lower thermal insulation board and support block, lower shoe is set under support block.Upper and lower thermal insulation board plays effect of heat insulation, and template heat dissipates when reducing production
Lose and environment, the influence of equipment, upper plate and lower shoe can be fixed and lifted.Four corners of described lower template are set
Locating piece and lead, four corners of cope plate set locating slot and pilot hole, registration, and open mold is oriented to stable.

Embodiment
A kind of zero polyurathamc injecting molding die is the utility model is related to, as shown in Fig. 1-Fig. 3, including cope plate 1
With lower template 2, die cavity 8 is set between cope plate 1 and lower template 2, places PHC sheet materials 7 in die cavity, in cope plate 1 and lower template 2
Heating pipeline 3 is respectively provided with, the external die heater of pipeline is heated, is set in cope plate 1 and vacuumize suction hole 4, vacuumized outside suction hole 4
Evacuator is connect, the side of lower template 2 sets injection port 5, and the opposite side of lower template 2 sets flash area 6, set in lower template 2
Adsorbing mechanism is put, PHC sheet materials 7 are absorbed and fixed in lower template 2 by adsorbing mechanism.During production, whole secondary mould is arranged on moulding press
In, cope plate 1 is first in die opening state with lower template 2, heats the pre-temperature of pipeline 3, then PHC sheet materials 7 are put into the die cavity 8 of lower template
In, and adsorbed and fixed by adsorbing mechanism, then upper and lower template matched moulds, polyurethane（PU）Material starts to inject at injection port 5, together
When, vacuumize suction hole 4 and suction is produced by external evacuator, by the polyurethane of injection（PU）Material is from true to taking out at sprue 5
Drawn at suction material hole 4, polyurethane（PU）Material flows through from the upper surface of PHC sheet materials 7, flows to flash area 6 always, forms a strata
Urethane coating 71, be like that one layer of polyurethane coating is coated in the upper surface of PHC sheet materials, when vacuumize be stopped after,
