Control part 200 at the double coloured plastic injection machine of this variation is also connecting drawer at movable side pressing mechanism drive division 206 and slider-actuated portion 205 etc.
Then utilize Figure 12 and Figure 16 A to describe the once-forming portion operation of the double coloured plastic injection machine of this variation.
First, control part 200, after having carried out mold closing action (S11), as shown in Figure 12 A, penetrates the first material from the not shown nozzle of the first ejaculator 203a, the housing 100 (S12) of shaping once-forming product.Now slide block 21 makes a part for slide block 21 be positioned at the relative position relative with housing 100.Then control part 200 is controlled the first plate drive division 201a, as shown in Figure 12 B, makes to water guidance tape 9 and moves to the direction of leaving runner plate 8, and make running channel flow path portion S1 expose (S13).Then, as shown in Figure 12 C, make the second plate 92 that waters guidance tape 9 leave the first plate 91, be easy to remove running channel flow path portion S1.
Then, control part 200 is removed the locking (S14) of shutter 19, controls fixation side pressing mechanism drive division 202a, as shown in Figure 12 D, makes pressing plate 71 to the first fixed side mold 10 side shiftings (S15).Thus, fixation side return pin 73 gives prominence to and makes Die and mould plate 6 and runner plate 8 to move to the direction of leaving drawer at movable side mould 12 from Die and mould plate 6.And meanwhile fixation side is outstanding by nail pressing 72, and the housing 100 as once-forming product is pressed into drawer at movable side mould 12.And now a part for slide block 21 is relative with a part for housing 100, stop housing 100 be maintained at the first fixed side mold 10 and move together with the first fixed side mold 10.Like this, in the double coloured plastic injection machine of variation, by slide block 21 and fixation side, by nail pressing 72, make housing 100 remain on drawer at movable side mould 12.And, in this variation, with the fixation side return pin 73 that is arranged at fixation side pressing plate 71, the first fixed side mold 10 is left with drawer at movable side mould 12.Therefore, can be synchronizeed the opportunity of leaving of the first fixed side mold 10 by the outstanding opportunity of nail pressing 72 with fixation side by simple structure.Thus, can with fixation side by nail pressing 72 really housing 100 by being pressed in drawer at movable side mould 12.
Then, by fixation side return pin 73, opened after ormal weight mould, control part 200 is controlled the first plate drive division 201a, as shown in Figure 12 E, makes Die and mould plate 6 and runner plate 8 move (S16) to the direction of leaving drawer at movable side mould 12.Thus, the first fixed side mold 10 is left drawer at movable side mould 12 completely.
Then utilize Figure 13 and Figure 16 B to describe the operation of the secondary forming portion 3 of the double coloured plastic injection machine of this variation.
First, control part 200 is after having carried out mold closing action (S21), as shown in FIG. 13A, penetrate basic synchronization with the first material dissolving in once-forming portion 2, from the not shown nozzle of the second ejaculator 203b, penetrate the second material (thermoplastic elastomer (TPE)) of dissolving (S22).So, the second material filling is to the space by remaining on the housing 100 of drawer at movable side mould 12 and the seal member forming section of the second fixed side mold 20 and forming, at the assigned position form seal parts 101 of housing 100.Now, the second material that injects to the space that the seal member forming section by housing 100 and the second fixed side mold forms from 4 cast gates, by the pathway shown in Figure 10, is finally filled to the overflow forming section 20a shown in Figure 14.Now, from injecting to the gas flow overflow forming section 20a of the second material production in above-mentioned space, and discharge from being arranged at the not shown air bleeding valve of overflow forming section 20a.By being set, overflow forming section 20a can obtain following effect.Even if that is to say gas not get rid of completely, be trapped in above-mentioned space and produce filling badness etc., the occurrence positions of its filling badness is the overflow part 101b (with reference to Figure 10) that is created in last filling the second material and is shaped.Thus, have and can suppress the part that causes because of the filling badness effect that filling etc. does not occur at the sealing 101c of seal member 101.And, owing at overflow forming section 20a, not shown air bleeding valve being set, at overflow part 101c, generating air bleeding valve trace, can not exert an influence to sealing.
After housing 100 seal members 101 are shaped, control part 200 is controlled the second plate drive division 201b, as shown in Figure 13 B, makes to water guidance tape 9 and runner plate 8 moves (S23) to the direction of leaving drawer at movable side mould 12.Thus, clamping block 23 leaves the outboard end of slide block 21.Then, control part 200 is controlled slider-actuated portion 205, as shown in Figure 13 C, gusset 26 is moved to drawer at movable side die side, and angle pin 22 is moved.So, the pin conical surface of front end in angle touches with the conical surface of the through hole 21a of slide block 21, makes slide block 21 to left side movement (S24) in figure.Thus, the relative part of the part with housing 100 of slide block 21 is kept out of the way.
Then, control part 200 is removed the locking (S25) of shutter 19, as shown in Figure 13 D, controls drawer at movable side pressing mechanism drive division 206, and drawer at movable side pressing plate 251 is moved to drawer at movable side die side.Thus, drawer at movable side return pin 253 is given prominence to and the Die and mould plate 6 of fixation side is moved from drawer at movable side Die and mould plate 24.And meanwhile drawer at movable side is outstanding by nail pressing 252, and the product of completing are pressed into the second fixed side mold 20.Now, as mentioned above, slide block 21 is kept out of the way, and due to not relative with housing 100, complete product and can by slide block 21, not stoped mobile and be kept by the second fixed side mold 20, and move together with the second fixed side mold 20.When this variation is left with moveable die 12 in the second fixed side mold 20, with drawer at movable side, by nail pressing 252, completing product, to the second fixed side mold 20, press.Thus, really can make product remain on the second fixed side mold 20.
Next, control part 200 is controlled the second plate drive division 201b, as shown in Figure 13 E, makes to water guidance tape 9 and moves (S26) to the direction of leaving runner plate 8.So, water guidance tape 9 and leave with runner plate 8, running channel flow path portion S2 exposes.Then as shown in Figure 13 F, make the second plate 92 that waters guidance tape 9 leave the first plate 91, running channel flow path portion S2 is easily removed.Then, control part 200 is controlled the second plate drive division 201b, as shown in Figure 13 G, Die and mould plate 6 and runner plate 8 is moved to the direction of leaving drawer at movable side mould 12, makes the second fixed side mold 20 leave drawer at movable side mould 12 (S28) completely.Next, the not shown fixture for having kept product is inserted into second fixedly between sidepiece 4b and the second movable sidepiece 5b.Then, control part 200 is controlled penetrating mechanism drive division 202b, as shown in Figure 13 H, makes ejection plate 71 to the second fixed side mold 20 side shiftings.So, completing product is taken off and is kept by fixture from the second fixed side mold 20 by ejecting plug 72.
In this variation, in once-forming portion 2, be provided with maintenance means, when these maintenance means are left for the first fixed side mold 10 when as the first mould and as the drawer at movable side mould 12 of mobile side mold, make housing 100 remain on drawer at movable side mould 12.Specifically, as maintenance means, there are following 2 structures.That is, first maintenance means are arranged on the first fixing sidepiece 4 of the first die side, the fixation side pressing mechanism 7 as the means of pressing of when making the first fixed side mold 10 leave drawer at movable side mould 12, housing 100 being pressed to drawer at movable side die side.Second maintenance means be free sliding be arranged on as the movable sidepiece 5 of the side that moves moulds with the first fixedly sidepiece 4 opposite faces, at least slide block 21 of the conduct relative parts relative with a part for housing 100 when making the first fixed side mold 10 leave drawer at movable side mould 12.When making the first fixed side mold 10 leave drawer at movable side mould 12, by fixation side pressing mechanism 7 by nail pressing 71 housing 100 by being pressed in drawer at movable side mould 12.And, now make a part for slide block 21 relative with housing 100, stop housing 100 to move together with the first fixed side mold 10.Thus, can make housing 100 really remain on drawer at movable side mould 12.
And, in this variation, for the place beyond the sealing 101c at seal member 101, be shaped and make the second material finally flow into the overflow part 101b of use and be provided with overflow forming section 20a in the second fixed side mold 20 as the second mould.Thus, even if there is the filling badness of the second material, its impact also occurs in the last overflow part 101b flowing into of the second material.Its result, can suppress local not filling etc. and occur at the sealing 101c of seal member 101, can be shaped and possess the housing 100 of the seal member 101 that can obtain good sealing property.
And, in this variation, due to also, at the inner peripheral surface of the first fixed side mold 12 Shaped shells 100, therefore can easily at the inner peripheral surface of housing 100, set cast gate.Thus, can not produce cast gate trace at the outer peripheral face of housing 100, so can suppress the infringement to products appearance.
And in above-mentioned variation, only left side is provided with slide block 21 in the drawings, but as shown in figure 17, a plurality of slide blocks 21 can be set.Structure shown in this Figure 17 is recess 24R, the 24L that left side and right side arrange rectangle in the figure of drawer at movable side Die and mould plate 24 and Die and mould plate opposite face fixation side, these recesses 24R, 24L free sliding be provided with slide block 21R, 21L.At the first forming section 2 Shaped shells 100, when the first fixed side mold 10 and moveable die 12 are left, as shown in figure 17, make in the part of slide block 21L in left side in figure and the figure of housing 100 left end relative.And, make in the part of slide block 21R on right side in figure and the figure of housing 100 right-hand end relative.Thus, slide block 21L, 21R can stop housing 100 to want to move together with the first fixed side mold 10, make housing 100 remain on drawer at movable side mould 12.Then, at secondary forming portion 3 product that have been shaped, when making the second fixed side mold 20 leave drawer at movable side mould 12, as shown in figure 18, the angle pin 22L that makes left side in figure is to fixing sidepiece side shifting, and the slide block 21L on the left of making in figure moves to arrow A 1 direction in figure.And the angle pin 22R that makes right side in figure is to fixing sidepiece side shifting, the slide block 21R that makes right side in figure moves to arrow A 2 directions in figure.Thus, slide block 21L, 21R keep out of the way, not relative with housing 100.After each slide block 21R, 21L keep out of the way, make the second fixed side mold 20 leave drawer at movable side mould 12.Now, each slide block 21R, 21L are at retreating position, not relative with housing 100, so the product of completing are maintained at the second fixed side mold 20, move together with the second fixed side mold 20.
