The specific embodiment

Further specify below in conjunction with the embodiment of accompanying drawing the utility model:

Like Fig. 1, shown in Figure 2, picking device in the secondary with plug-in type fixed mechanism of injection mold comprises moving platen 19, and gun barrel 10 is installed on the moving platen 19, and gun barrel 10 is for having the hollow cylinder of an end cap.

Being provided with in the gun barrel 10 can be along guiding I-shaped piece 5, spline piece 4 and the slide rail 9 of gun barrel 10 inwalls slip, and wherein slide rail 9 is the uncovered hollow cylinder, and guiding I-shaped piece 5 is fixed with an end of contiguous block 8.

Contiguous block 8 is a cylinder, has groove 81 between wherein, and the center is shaped on tie rod holes 82, and is as shown in Figure 5.

Spline piece 4 is arranged in groove 81, and its width is corresponding with groove 81 width; The two ends of spline piece 4 are the arc structure that cooperates with gun barrel 10 inwalls, and fix with the right side of slide rail 9, and its effect is to prevent that contiguous block 8 from producing rotation in sliding process, and is as shown in Figure 4.

The other end of contiguous block 8 is fixed with slider guide 1 through screw, is furnished with eight slide blocks 2 on the slider guide 1, and wherein contiguous block 8 all can slide along slide rail 9 inwalls with slider guide 1.

Slider guide 1 is Rotary-table, is shaped on equally distributed 8 oblique I-shaped grooves 11 in slider guide 1 side along generatrix direction, like Fig. 3 and shown in Figure 6.

Eight slide blocks 2 are present mould applications a kind of mechanisms commonly used; The loop configuration that it is made up of 8 slide blocks, " design of the eight slide block PVC tubing bulging moulds " literary composition that specifically can write referring to Chen Jun honor in the periodical " mould manufacturing-2006 year 5 phases ", Cui Caifen, Liu Xiuhuan.All be shaped on inner slide 22 on the every slide block of eight slide blocks 2, inner slide 22 matches with the structure of oblique I-shaped groove 11, like Fig. 6 and shown in Figure 9.

Also be shaped on bulge loop 21 on eight slide blocks 2, as shown in Figure 8.Bulge loop 21 is used to make annular back-off 20 moulding of pipe fitting.

Have first blind hole at spline piece 4 centers, be fixed with connecting rod 3 in first blind hole, behind the tie rod holes 82 that connecting rod 3 runs through contiguous block 8 successively and the slider guide 1 its end away from first blind hole is stretched in second blind hole on the fuse 6, as shown in Figure 2.

Like Figure 12, shown in Figure 13; The one side that is shaped on first blind hole at spline piece 4 is shaped on draw-in groove; Be fixed with the connecting rod card article 41 that size cooperates with draw-in groove in the draw-in groove; Its fixed form can for: be shaped on groove (projection) in connecting rod card article 41 two sides, on the draw-in groove wall of spline piece 4, be shaped on projection (groove), be fixed through projection and groove; Also can directly connecting rod card article 41 be locked in and realize on the spline piece 4 fixing with screw; It is fixing to adopt above-mentioned dual mode to realize simultaneously.Radially have through hole in connecting rod 3 and the corresponding position of draw-in groove, connecting rod card article 41 is inserted through through hole, realizes the fixing of connecting rod card article 41 and spline piece 4.

Second blind hole on the fuse 6 is step-like, comprises first step 61, second step 62 and the 3rd step 63 from inside to outside successively, and connecting rod 3 stretches in the first step 61 away from an end of first blind hole, like Figure 10 and shown in Figure 11.

Being provided with in the second step 62 can be along the I-shaped slide block 12 of second step 62 walls slip; Wherein I-shaped slide block 12 is fixing with connecting rod 3; Be connected with 8 on the I-shaped slide block 12 and take out piece 13 in slidably; Take out piece 13 in every and be shaped on projection 14 away from the end of I-shaped slide block 12, projection 14 is used to make block back-off 30 moulding of pipe fitting.Take out piece 13 in 8 and radially evenly distribute radially, and run through fuse 6 and make projection 14 expose the outer wall of fuse 6 along fuse 6, I-shaped slide block 12 and in the matching relationship taken out between the piece 13 identical with matching relationship between slider guide 1 and eight slide blocks 2.

In the 3rd step 63 fuse fixed block 16 is installed.After I-shaped slide block 12 slides the h distance to the right, will run into fuse fixed block 16 and stop slip, and avoid coming off.

Oil cylinder 7 is installed on the right end cap of gun barrel 10, and the cylinder rod 71 of oil cylinder 7 passes right end cap and is connected with guiding I-shaped piece 5.

As further optimization to technique scheme; Can also on eight slide blocks 2, be provided with the water route cooling body; The water route cooling body specifically comprises; Be shaped on the flowing water passage in each slide block on eight slide blocks 2, the two ends of flowing water passage all are opened on shoe surface and form entery and delivery port, and water pipe all is installed on the entery and delivery port.Can be straight water pipe 23 of the equal separate configurations of each entery and delivery port, also can be only to part entery and delivery port configuration straight water pipe 23, all the other entery and delivery ports are communicated with through connecting water pipe 24, and are as shown in Figure 9.Through connect 24 pairs of entery and delivery ports of water pipe be communicated with its advantage be take up room little.

It is following to take out working process of mechanism in this secondary:

After the die sinking, oil cylinder 7 drives guiding I-shaped piece 5 through cylinder rod 71 and slides to the right, and the I-shaped piece 5 that leads simultaneously drives contiguous block 8, contiguous block 8 drives slider guide 1 and slides to the right; And other parts such as spline piece 4, connecting rod 3, slide rail 9 all remain on original position at this moment, and in this process, eight slide blocks 2 will inwardly shrink under the effect of oblique I-shaped groove 11; Bulge loop 21 also slowly breaks away from annular back-off 20; Until the contiguous block 8 H distance that moves right, spline piece 4 is run in the left part 83 of contiguous block 8, at this moment; Bulge loop 21 breaks away from annular back-off 20 fully, so far accomplishes in the first time and takes out.

Oil cylinder 7 drives guiding I-shaped piece 5, contiguous block 8 and slider guide 1 to be continued to slide to the right; Because spline piece 4 has been run in the left part 83 of contiguous block 8, so spline piece 4 drivening rods 3, connecting rod 3 drive I-shaped slide blocks 12 and slide to the right synchronously, and in this process fuse 6 and fuse fixed block 16 still to remain on original position motionless; With take out in the first time in like manner under the effect of the oblique I-shaped groove on the I-shaped slide block 12; In take out piece 13 and inwardly slide, in the projection 14 taken out on the piece 13 also slowly break away from the block back-off 30 on the pipe fitting, until the contiguous block 8 I-shaped slide blocks 12 h distance that moves right again; I-shaped slide block 12 is run into fuse fixed block 16; At this moment, projection 14 breaks away from block back-off 30 fully, so far accomplishes in the second time and takes out.

Oil cylinder 7 drives guiding I-shaped piece 5, contiguous block 8, slider guide 1, spline piece 4, connecting rod 3 and I-shaped slide block 12 to be continued to slide to the right; Because I-shaped slide block 12 has been run into fuse fixed block 16; Therefore fuse fixed block 16 and fixing with it fuse 6 also slide to the right; Break away from from pipe fitting until fuse 6, accomplish the whole process of loosing core.

By on can find out that smoking in twice links up with three processes of once loosing core carries out, and has therefore shortened the production cycle of pipe fitting, has improved production efficiency.

More than describe the preferred embodiment of the utility model in detail.The ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technical staff in the art, all should fall in the protection domain of the utility model on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment according to the design of the utility model.
