A kind of bicolor injection mould structure motion process that the utility model embodiment provides is as follows:
Step 1: injection machine drives described first dynamic model 300 and second dynamic model 400 moves forward simultaneously, makes first dynamic model 300 and the first look cover half, 100 matched moulds, second dynamic model 400 and the second look cover half, 200 matched moulds.Briquetting 320 on the first look cover half 100 compresses first release link, 312 ends in described first dynamic model 300 at this moment, this moment, described first release link 312 was 0 (with reference to shown in Figure 15) with the distance L 4 of cavity plate 305, described warpage bar 310 is under the effect of described first release link, 312 pressure, power is passed to described pin push pedal 304 and described pin push pedal 304 is moved upward, thereby the described pin 301 and second release link 313 are moved upward, pin fixed head 303 supports and terminates in (with reference to shown in Figure 14) on the described core plate 302, distance L 3 between described pin fixed head 303 and the core plate 302 is 0 (with reference to shown in Figure 16) at this moment, and make pin 301 be higher than the die joint (with reference to shown in Figure 21) of mould, participate in moulding can be entered its closed inner chamber 92 for the second coloring agent material by product ring-type font product profile 91 outsides passage 9, second release link, 313 ends are higher than the mould die joint and stretch in first cavity 321 at this moment, the distance that described second release link 313 stretches into described first cavity 321 is L2, and the empty avoiding distance of described second release link 313 and first cavity 321 is L1 (with reference to shown in Figure 13).
Step 2: injection machine is injected the first coloring agent material with moulding ring-type font product profile 91 parts in the first look cover half 100, the second look cover half 200 is in idle state in this step, does idle stroke, does not inject.
Step 3: injection machine is opened mould, injecting the product that the first coloring agent material moulding obtains stays in first dynamic model 300, injection machine drives behind first dynamic model 300 and second dynamic model, the 400 Rotate 180 degree matched moulds once more, this moment the first look cover half 100 and second dynamic model, 400 matched moulds, the second look cover half 200 and first dynamic model, 300 matched moulds, briquetting 320 on the first look cover half 100 compresses first release link, 312 ends in described second dynamic model 400, described warpage bar 310 is under the effect of described first release link, 312 pressure, power is passed to described pin push pedal 304 and described pin push pedal 304 is moved upward, thereby the described pin 301 and second release link 313 are moved upward, and make described pin 301 be higher than the die joint of mould, participate in moulding can be entered its closed inner chamber 92 for the second coloring agent material by product ring-type font product profile 91 outsides passage 9, second release link, 313 ends were higher than the mould die joint and stretched into first cavity 321 this moment, and pin fixed head 303 supports and terminates on the described core plate 302.Cavity plate 305 on the described second look cover half 200 is pressed in second release link, 313 ends in described first dynamic model 300, described second release link 313 is moved downward, the distance L 6 that described second release link 313 and cavity plate are 305 is 0 (with reference to shown in Figure 17), drive described pin fixed head 303 simultaneously, pin push pedal 304 and pin 301 move down synchronously, distance between described pin fixed head 303 and the core plate 302 is L7 (with reference to shown in Figure 180) at this moment, thereby pin 301 is extracted out from the product of injecting the first coloring agent material and obtaining, obtain to enter by product ring-type font product profile 91 outsides for the second coloring agent material passage 9 (with reference to shown in Figure 22) of its closed inner chamber 92, described pin push pedal 304 moves down and compresses warpage bar 310, move and stretch on described first release link 312 in second cavity interior 322 thereby make, the distance that described first release link 312 stretches into second cavity interior 322 is L8, and the empty avoiding distance of described first release link 312 and second cavity 322 is L5 (with reference to shown in Figure 19).
Step 4: injection machine is injected the first coloring agent material with moulding ring-type font product profile 91 parts in the first look cover half, in the second look cover half 200, inject the second coloring agent material simultaneously, the second coloring agent material passage 9 of can flowing through outside ring-type font product profile 91 enters its closed inner chamber 92, obtains complete dual-color plastic product.After injection is finished, injection machine drives mould and divides mould, thimble push pedal 307 moves forward in the relative core plate 302 of the effect of top rod with thimble fixed head 306, driving the product that 308 reaches of described thimble will finish after the injection of the second coloring agent material simultaneously ejects, obtain the product of ring-type font product profile 91 in second dynamic model 400, finish an injection cycle.
Step 5: injection machine drives injection machine and drives behind first dynamic model 300 and second dynamic model, the 400 Rotate 180 degree matched moulds once more, described first dynamic model 300 and the first look cover half, 100 matched moulds, second dynamic model 400 and the second look cover half, 200 matched moulds, injection machine is to the first look cover half, 100 injections, the first coloring agent material, simultaneously to the second look cover half, 200 injections, the second coloring agent material, after injection moulding was finished, the product that thimble 308 will be finished after the injection of the second coloring agent material ejected.
Repeating step 3 to step 5 can continuously be produced the bicolor plastic cement product of annular enclosed word or figure, and mould structure is simply ingenious, and the Mold Making cost is low, and the Mold Making cycle is short, and the production efficiency height helps reducing product cost.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
