The course of work according to dijection injection mold of the present invention is as follows:
The control injection machine is drawn close dynamic model part 30 to quiet mould part 20, and realizes matched moulds, carries out injection moulding then.In quiet mould side, because the existence of return push rod 27, when matched moulds arrives certain position, return push rod 27 just can contact with male model plate 36, and under the impetus of male model plate 36, carry out return, and drive about in the of the 3rd liftout plate 25 and the 4th up and down liftout plate 26 do returning movement, when finishing matched moulds, the 3rd about about the liftout plate 25 and the 4th liftout plate 26 also finish revert action.Since driving lever 23 only exists and the first quiet mould 21 on, therefore, under the effect of driving lever 23, in the matched moulds process, the slide block 34 of the dynamic model that cooperates with the first quiet mould 21 part is drawn close to mold center, under the effect of inferring on inclined-plane, the liftout plate 33 about in the of second that is positioned at first shaping area that cooperates with the first quiet mould 21 moves upward, driving advance and retreat disposed thereon inserts and 331 moves upward, after finishing matched moulds, this group advance and retreat are inserted and 33 are in the state that stretches out, and complement each other to form the first colour solid forming cavity of moulding first colour solid 10 with the male model benevolence 31 that is positioned at first shaping area and first mother module core 213, carry out injection moulding then, the first colour solid mould material that will be connected with first adaptor 211 injects mould by injection machine, the mould material flows into the first flow 311 that is positioned on the male model benevolence 31 through first adaptor 211, flowing into first of each first colour solid forming cavity respectively along first flow 311 then advances in the cast gate 312, and advance cast gate 312 by first and carry out injection moulding, pass through abundant material feeding then, pressurize, make the mould material fully flow to the various piece of the first colour solid forming cavity, finish injection moulding first colour solid 10.
When carrying out the branch mould, the injection machine that is connected with dynamic model part 30 begins to retreat, driving dynamic model part 30 retreats, in the separated process of feature die, under the effect of the driving lever 23 that is positioned at first shaping area, slide block 34 beginnings are to the direction motion of deviating from mould, correspondingly, liftout plate 33 beginnings descend gradually about in the of second, the advance and retreat that drive is positioned at first shaping area 331 withdrawals of inserting, when slide block 34 moves to the precalculated position, promptly during the position of stop screw 341, the insert die joint of 331 upper surface, edge and male model benevolence 31 of advance and retreat is in the same plane.Under the effect of drawing the material pin, product is left on the male model side.
Same, when minute mould, owing to be subjected to the elastic reaction of limit spring, liftout plate 26 meetings separately moving about the liftout plate 25 and the 4th about in the of the 3rd along with feature die to the male model side direction, under the impetus of the master mold side thimble 251 on the liftout plate 25 about in the of the 3rd, first colour solid 10 also can be to the male model lateral movement, thereby makes first colour solid 10 be retained in the male model side, can prevent effectively that product from gluing master mold.When moving to the bottom position of caster, under the obstruction effect of caster, liftout plate 25 stop motions about in the of the 3rd, and static with first caster 212, detach the master mold side fully until the male model side.
After finishing injection moulding for the first time, under the effect of injection machine, dynamic model part 30 Rotate 180 degree, first colour solid of finishing after the injection moulding is for the first time followed dynamic model partial rotation 180 degree of finishing injection moulding for the first time, and goes in second shaping area.Left residual mould material is cut off from flow field end after this moment of the injection moulding for the first time, so that be the moving slot milling of mould materials flow of the injection moulding second time.
When carrying out second time injection moulding, still carry out matched moulds earlier.When carrying out matched moulds, dynamic model part 30 is drawn close to quiet mould part 20, and the part that has first colour solid 10 on it is positioned at the position corresponding with the second quiet mould 22.Because driving lever 23 exists only in first quiet mould 21 sides, therefore during matched moulds, insert 331 position of the advance and retreat that are positioned at second shaping area can not change, and 331 the cavity that stays in first colour solid 10 that is retracted in still keeps because advance and retreat are inserted after the first time, moulding was finished.
When finishing matched moulds, second adaptor 222 be enclosed within moulding for the first time on the residual mould material, and leave the moving space of enough mould materials flows.Because the first flow 311 inflow die cavitys of injection mo(u)lding for the first time from being positioned at the male model side, therefore, when second time injection moulding, first flow 311 still has been full of residual mould material.Therefore, the runner of injection moulding for the second time is second runner 2211 that is arranged on the mother module core, can guarantee that the mould material has the good mobility energy after entering second runner 2211.
Carry out the injection moulding second time after finishing matched moulds, be connected to the mould material place of second colour solid 11 by second adaptor 222, the mould material of second colour solid 11 enters second runner 2211 through second adaptor 222 then, the mould material that enters in second runner 2211 advances in the cast gate 2212 inflows second colour solid forming cavity from being arranged on second on the male model benevolence 31, because second advances cast gate 2212 when first time moulding and unoccupied, be not communicated with the runner of the moulding first time yet, therefore remain unimpeded, use in the time of can be for second time injection moulding.
The mould material of second colour solid advances cast gate 2212 through second runner 2211 and second and flows in the second colour solid forming cavity, through abundant material feeding and pressurize, finishes injection moulding at last.
Carry out die sinking then, by injection machine feature die is separated, owing to draw the effect of material pin, product is stayed the male model side, promote liftout plate 32 about in the of first by the push rod on the injection machine then, and then drive is positioned at, and the male model side thimble 321 on the liftout plate 32 moves upward about in the of first, product behind the quadric injection mould is ejected, the product that will have residual runner mould material is then handled through ultrasonic unit, the mould material shake that to enter the cast gate place is disconnected, simultaneously can not damage product and advance cast gate, make product have preferable quality.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect: according to technical scheme of the present invention, have between the dichromatism material of dual-color plastic rod to be and disconnect the surface that shape distributes fully, and the dichromatism material all is formed in one.The dynamic model of dijection injection mold partly is provided with advance and retreat and inserts, these advance and retreat are inserted and are arranged on about in the of second on the liftout plate, move with liftout plate about in the of second, and when moulding first colour solid, be in the state of stretching out, when moulding second colour solid, be in retracted mode, like this, when moulding second colour solid, the retraction because advance and retreat are inserted, first colour solid was placed the part of inserting of advancing and retreat originally and had just been had inner chamber, this inner chamber is communicated with the groove that each spaced surface of first colour solid distributes, when carrying out second time injection moulding, the mould material flows in each groove from inner chamber, and second colour solid and first colour solid are closely linked, and presents striated pattern spaced apart spaced apart on the surface.Advance and retreat are inserted and adjusted its height up and down by the slide block that cooperates with its inclination, and are simple in structure, easily and effectively, are convenient to operation.Quality of fit when the location structure between the male and female template further improves the moulding of male and female die, thus the formed product precision improved.
