Specific embodiment
The invention will be further described with the following Examples.
A kind of specific embodiment of injection mold sliding block anti-back structure of the invention, as depicted in figs. 1 and 2, including
Hydraulic cylinder 5, linkage seat 1, sliding block 3 and T-block 2, the piston shaft 4 and linkage seat 1 of hydraulic cylinder 5 are affixed, the bottom face of linkage seat 1 by
The first horizontal plane 11 and inclined first inclined-plane 12 composition, the longitudinal sections 21 of T-block 2 are inserted into and are fixed in linkage seat 1
First inclined-plane 12, see Fig. 7, sliding block 3 offers T-type fluting 33, and in the assembled condition, the traversing section 22 of T-block 2 is inserted into T-type
Can slot in fluting 33 and relative to T-type and 33 slide, the top end face of sliding block 3 by second plane 31 parallel with the first plane 11 and
Second inclined-plane 32 composition parallel with the first inclined-plane 12.
It is that, see Fig. 2, the second plane 31 and the second inclined-plane 32 correspondingly offer the first right-angle notch 61 as improved
With the second right-angle notch 62, the lateral face of the lateral face 611 of the first right-angle notch 61 and the second right-angle notch 62 is flat with second
Face 31 is parallel, and T-block 2 is connected with the first clamping block 7 close to the end of the first right-angle notch 61, and the length of the first clamping block 7 is small
In or equal to T-block 2 width and may pass through T-type fluting 33, the first plane 11 of linkage seat 1 is connected with the second clamping block 8, the
The lateral bottom face of one clamping block 7 is parallel with the second plane 31 with the lateral bottom face 81 of the second clamping block 8, T-type fluting 33
There are the free gap 9 in T-type fluting 33 is slid into for the first clamping block 7 between the T-block 2 of position in the inner；Under molding state,
See Fig. 4 and Fig. 6, the bottom face of the first clamping block 7 resists the lateral face 611 of the first right-angle notch 61, the first right-angle notch 61
Longitudinal surface 612 do not contacted with the first clamping block 7, the lateral bottom face 81 and longitudinal side 82 of the second clamping block 8 are respectively held against
The lateral face of second right-angle notch 62 and longitudinal surface.
The course of work of the injection mold of the present embodiment sliding block anti-back structure, see Fig. 1 to Fig. 7, under injection state,
Hydraulic cylinder 5 drives piston shaft 4 to work, and piston shaft 4 drives linkage seat 1 mobile towards the left side Fig. 1, and injection molding can apply one to sliding block
A pressure, so that the first inclined-plane 12 that the second inclined-plane 32 of sliding block 3 will be bonded linkage seat 1 (pastes the traversing section top surface of T-block 2
Top surface in nearly T-type fluting 33), when pressure is excessive, sliding block 3 will have a trend along the first inclined-plane 12 or the second inclined-plane 32
It is slided, and the anti-back structure of this implementation is locked by the way that the first of mutual clamping is respectively set at the left and right ends of sliding block 3
The second clamping block 8 and the second right-angle notch 62 of block 7 and the first right-angle notch 61 and mutually clamping, and then limit sliding block 3
It is slided along inclined-plane, the lateral face of the right-angle structure of the first right-angle notch 61 and the second right-angle notch 62 is able to bear T-block 2
Or the pressure straight down that linkage seat 1 is applied, the longitudinal surface of the right-angle structure of the second right-angle notch 62 are able to bear prevention
The power for the horizontal direction that sliding block 3 moves obliquely so as to the retrogressing of anti-limited slip block, and then extends the use longevity of demoulding mechanism
Life；In addition, there are slided between the activity of T-type fluting 33 for the first clamping block 7 between the T-block 2 of T-type fluting 33 and position in the inner
Gap 9, in mode-lock status, free gap 9 is located at the top of T-block 2, and the first clamping block 7 is located at the first right-angle notch 61；?
When demoulding state, free gap 9 is located at the bottom of T-block 2, and the first clamping block 7 is located in T-type fluting 33.In de-filming process,
The right that hydraulic cylinder 5 drives piston shaft 4 towards the direction Fig. 1 bounces back, and drives the first clamping block 7 to right translation, and the first clamping block 7 is sliding
Enter T-type fluting 33, limit of second clamping block 8 to left and releasing to sliding block 3, then sliding block 3 can be along the second inclined-plane
32 are slided, to realize that demoulding acts, in addition, the free gap 9 between T-type fluting 33 and T-block 2, can mention for sliding block 3
The space buffered for one section after sliding block 3 can be moved a certain distance relative to linkage seat 1, just will receive pressure during the work time
Effect, avoid the instantaneous stress of sliding block 3 excessive and damage, further prolong the service life.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered
Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention
Matter and range.
