Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As the embodiment one of high-precision injection mold described in the utility model, as shown in Figure 1, pulling 1, dynamic model including cover half
Plate 2, side pumping slider 3 and inclined guide pillar 4, the solid plate 1 are equipped with through-hole 101, and the inclined guide pillar 4 is fixed on the logical of solid plate 1
On hole 101, the side pumping slider 3 be equipped with 4 matched inclined hole 31 of inclined guide pillar, further include and be fixed on supporting on solid plate 1
Briquetting 5,5 inside of press block are equipped with inclined-plane 51, also are provided with inclined-plane 32 on 3 outside of side pumping slider, are compressed in molding
The inclined-plane 51 of 5 inside of block and the inclined-plane 32 in 3 outside of side pumping slider abut against.
The high-precision injection mold includes side core-pulling structure, is still coordinated using side pumping slider of the prior art and inclined guide pillar
Structure, but be additionally arranged press block 5, i.e., every time molding when, horizontal direction that side pumping slider 3 can all be transmitted by press block 5 pushes away
Power fixes the position of side pumping slider 3, will not generate floating space because of having gap between inclined guide pillar 4 and inclined hole 31, institute
To improve the measure of precision of injecting products size.
In the present embodiment, fixed block is also fixed on the solid plate 1, the fixed block is distributed in side pumping slider
Two sides, fixed block can play guiding role, and fixed block can also be defined in the longitudinal direction, improve in the front-back direction
Product Precision.
Existing inclined guide pillar is arranged on solid plate, is in tilted layout, the space needed is larger, causes die size that can not contract
It is small, it can not further reduce the cost.In order to solve this problem, in the present embodiment, the inclined guide pillar 4 includes 41 He of straightway
Oblique line section 42, the straightway 41 are matched with the through-hole 101 of solid plate 1, and the oblique line section 42 is matched with inclined hole 31, described
Angle between straightway 41 and oblique line section 42 is 150-160 degree.Through-hole 101 first on solid plate 1 is positive hole, processing side
Just, inclined guide pillar 4 is easily mounted on solid plate 1, and secondly, distance is taken out in similary side can reduce the size of solid plate 1, so as to reduce
Mold Making cost.
As the embodiment two of high-precision injection mold described in the utility model, as shown in Fig. 2, it is different from embodiment one it
It is in being additionally provided with side core-pulling bar 6 and resetting spring 7 in the side pumping slider 3, the side pumping slider 3 is equipped with through-hole 33, institute
It states side core-pulling bar 6 to be slidably arranged in the through-hole 33, the solid plate 1 is equipped with stent 8, and the stent 8 is equipped with fixed sliding
Wheel 9,10 one end of driving rope are fixed on solid plate 1, and the other end is fixed on side core-pulling bar 6.Fig. 2 is ladder cut-away view,
Left-half is half cut-away view, and right half part is cut-away view at the shaft core of side core-pulling bar, and the inclined guide pillar on right side still has, only
It does not cut open, so not showing.
In the present embodiment, the locating piece 11 for fixed reset spring 7 is additionally provided on the moving platen 2.In die sinking,
Moving platen 2 retreats, and inclined guide pillar 4 drives 3 normal side of side pumping slider to take out, and driving rope 10 drives side core-pulling bar 6 to carry out side pumping, driving
The tightness of rope 10 determines that opportunity is taken out in the side of side core-pulling bar 6；In molding, 7 push side core_pulling pole 6 of resetting spring resets.
When there is more groove in the side of product, takes out hole or cylinder, if being carried out at the same time side pumping, larger side is needed to take out
Power, it is necessary to which thicker inclined guide pillar can influence die size and cost, and product side is easily pulled out of shape, and precision is not easy
Control.The side pumping slider 3 of the present embodiment is normally carried out side pumping, but by the way of side core-pulling bar 6 is taken out using slow side, in side pumping slider
It takes out after a distance or finishes and then carry out side pumping in 3 sides, it is only necessary to which control driving 10 tightness of rope can control
The side of side core-pulling bar 6 is taken out opportunity, and adjustment is very convenient, can be reduced the deformation of product side, be improved Product Precision.Other structures and
Advantageous effect is consistent with embodiment one, and details are not described herein again.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
