The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present invention is further specified:
Like Fig. 1, shown in Figure 2, pump structure in the secondary 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.
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.
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 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 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 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.
Be shaped on crank-guide way on the connecting rod card 41; Connecting rod 3 both sides are shaped on the recess that cooperates with the crank-guide way two side, because connecting rod 3 both sides are shaped on recess, so this part of connecting rod 3 diminishes; Can just insert crank-guide way, and the crank-guide way two side just is stuck in also in the recess that connecting rod 3 both sides are shaped on.Realize the fixing of spline piece 4 and connecting rod 3 through this structure.
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.
Like Figure 14, shown in Figure 15; As a kind of distortion to technique scheme; Fixed form between spline piece 4 and the connecting rod 3 can be employed in the one side that spline piece 4 is shaped on first blind hole and be fixed with connecting rod clamp 42, and the size of connecting rod clamp 42 cross sections matches with the size of spline piece 4 cross sections, is shaped on crank-guide way on the connecting rod clamp 42; Connecting rod 3 both sides are shaped on the recess that cooperates with the crank-guide way two side, in like manner also realize the fixing of switch block 4 and connecting rod 3.But the present technique scheme ends can lock through screw between switch block 4 and the connecting rod clamp 42, but can't be fixed through projection and groove.
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.
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 preferred embodiment of the present invention in detail.The ordinary skill that should be appreciated that this area need not creative work and just can design according to the present invention make many modifications and variation.Therefore, all technical staff in the art on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment, all should fall in protection scope of the present invention under this invention's idea.
