Description
Technical field
The utility model relates to that a kind of gas of automobile instrument panel storing cover mold tool is auxilliary to subtract gluing mechanism, belongs to auto parts machinery mfg. moulding die technical field.
Background technology
Whole attractive in appearance in order to make in the compartment, lid is installed on the storage tank of automobile is given a kind of comfort of people.The edge of lid is shaped on rib, will handle the surface and the good looking appearance of appropriate assurance lid in the process of producing to rib.The edge of prior art lid is shaped on whole circle rib, be used for assembling and booster action, but there is shortcoming in it: in actual production, bead zone thickness causes wall unevenness even more easily, and rib processing difficulties and be difficult to solve rib and cause product surface epitome problem, influence the overall appearance of instrument board, reduce the car load class.
Summary of the invention
The purpose of this utility model is the shortcoming at prior art, and the auxilliary gluing mechanism that subtracts of gas of the automobile instrument panel storing cover mold tool that a kind of product wall thickness is even, the no epitome in surface is out of shape is provided.
The technical scheme that the utility model adopted is to achieve the above object of the invention:
The auxilliary gluing mechanism that subtracts of the gas of automobile instrument panel storing cover mold tool, comprise compound plate and following compound plate, last compound plate connects die cavity by the die cavity heat flux plates, following compound plate is installed core by the mould pin, constitute die cavity between die cavity and the core, it is characterized in that being shaped in the described core breather line that is used for logical inert gas, breather line connects air pins, air pins is installed in the core and is opened on die cavity, is provided with flash groove in the described core, and flash groove is opened on die cavity, there is cylinder the below of flash groove, cylinder is installed in the core, the Kai Heguan of the cylinder rod control flash groove of cylinder, and described air pins and cylinder are controlled by injection machine.
The technical program is in injection moulding process, cylinder rod and die cavity bump extremely (being that cylinder rod is closed flash groove) and prevent that materials flow from going in the flash groove, the air pins closure, treat injection moulding finish after constant pressurize, injection machine control this moment inert gas is entered by breather line, air pins is opened entered cavity, enters cavity injection machine startup simultaneously cylinder at inert gas, cylinder rod separates with die cavity opens flash groove, and the local thicker region sizing material of product is clamp-oned flash groove by inert gas.After injection moulding was finished, injection machine stopped to import inert gas, started cylinder and closed flash groove, the cooling die sinking.The technical program is utilized the inert gas characteristics, and it is even that the equal volume inert gas is extruded the sizing material solution product wall unevenness of equal volume, solves product epitome problem on deformation simultaneously, improves the attractive in appearance of instrument board surface.Be drilled with breather line in core, breather line links to each other with air pins, and the air pins ventilation is smooth and easy, reliable.
Fix straight guide pin bushing on the described die cavity, fix straight guide rod on the core, straight guide rod matches with straight guide pin bushing.There had the straight guide rod that cooperatively interacts and straight guide pin bushing that core is moved up and down to be more stable.
The inert gas of described breather line is a nitrogen.The advantage of nitrogen is a low price.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that the inert gas of the utility model embodiment flows to schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As depicted in figs. 1 and 2, the auxilliary gluing mechanism that subtracts of the gas of automobile instrument panel storing cover mold tool, comprise compound plate 2 and following compound plate 11, last compound plate 2 connects die cavity 4 by die cavity heat flux plates 3, following compound plate 11 is installed core 6 by mould pin 7, constitute die cavity between die cavity 4 and the core 6, it is characterized in that being shaped in the described core 6 breather line 8 that is used for logical inert gas 12, breather line 8 connects air pins 1, air pins 1 is installed in the core 6 and is opened on die cavity, be provided with flash groove 10 in the described core 6, flash groove 10 is opened on die cavity, and there is cylinder 13 below of flash groove 10, and cylinder 13 is installed in the core 6, the Kai Heguan of the cylinder rod 14 control flash grooves 10 of cylinder 13, described air pins 1 and cylinder 13 are controlled by injection machine.The technical program is in injection moulding process, cylinder rod 14 and die cavity 4 bump extremely (being that cylinder rod 14 is closed flash groove 10) only materials flow go in the flash groove 10, air pins 1 closure, treat injection moulding finish after constant pressurize, injection machine control this moment inert gas 12 is entered by breather line 8, air pins 1 opened enter cavity, enter cavity injection machine startup simultaneously cylinder 13 at inert gas 12, cylinder rod 14 separates with die cavity 4 opens flash groove 10, and the local thicker region sizing material of product is clamp-oned flash groove 10 by inert gas 12.After injection moulding was finished, injection machine stopped to import inert gas 12, started cylinder 13 and closed flash groove 10, the cooling die sinking.The technical program is utilized inert gas 12 characteristics, and it is even that equal volume inert gas 12 is extruded the sizing material solution product wall unevenness of equal volume, solves product epitome problem on deformation simultaneously, improves the attractive in appearance of instrument board surface.Be drilled with breather line in core, breather line links to each other with air pins, and the air pins ventilation is smooth and easy, reliable.Fix straight guide pin bushing 9 on the described die cavity 4, fix straight guide rod 5 on the core 6, straight guide rod 5 matches with straight guide pin bushing 9.There had the straight guide rod that cooperatively interacts and straight guide pin bushing that core is moved up and down to be more stable.The inert gas of described breather line 8 is a nitrogen.
