Detailed description of the invention
For convenient understanding structure of the present utility model, describe with reference to the accompanying drawings acceleration liftout attachment of the present utility model below in detail.
As shown in Figure 1, slanted kicking block 1 is supported by two angle ejector rods 5.
As shown in Figure 6, the angle of inclination of angle ejector rod 5 and Angle Pin 11 is α=16 °, and Z-direction ejects distance for H 1=70mm, oblique top directions X Core-pulling distance is from being L 1=20.07mm, is greater than the back-off of plastic products 17 apart from 16.17mm.The guide runner angle of guide sliding base 13 is β=18 °, and in the situation that ejecting 70mm, slide block 14 is H along guide runner at the climb of Z direction 2=6.52mm.The height of the solidifying material of cold slug well is 6.27mm, so sprue puller 15 can be by the solidifying material of cold slug well ejection pitched roof piece 1.
The reasoning process of all angles is as follows:
This mould ejection distance is H 1=70mm, goods herein maximum back-off distance are 16.17mm, therefore slant-top core-pulling distance L 1should be greater than the safe distance of back-off distance+3mm, i.e. L 1=H 1tan α > 19.17mm,
Calculate 15.32 ° of α >, round numerical value α=16.
The actual distance L of loosing core of oblique top 1=H 1tan α=70 × tan16 °=20.07mm,
In this oblique top, the degree of depth of the solidifying material of cold slug well is 6.27mm, and therefore sprue puller is with respect to the distance H that ejects of slanted kicking block Z direction 2> 6.27mm, i.e. H 2=L 1tanb > 6.27mm, calculates 17.35 ° of b >, rounds numerical value b=18 °,
Actual distance H=the H that ejects of sprue puller 1+ H 2=70+20.07 × tan18 °=76.52mm.
Can find out by above reasoning, by changing guide runner upward slope angle b value, just can change and accelerate to eject distance.
The detailed course of action of this acceleration liftout attachment is as follows:
The action of Slanted ejecting component: in the time of mould ejection, ejector retainner plate 19, end needle plate 20 move along Z-direction, Slanted ejecting component moves upward along angle ejector rod direction under the slip guiding sleeve 4 of angle ejector rod 5 and the guide effect of Angle Pin 11, under the guide effect of slide pressing plate 7, oblique-top sliding seat 6 moves along directions X with respect to end needle plate 20, Slanted ejecting component also for along the moving of directions X, has so just completed the motion of loosing core of plastic products back-offs with respect to the direction of motion of plastic products 17.
Accelerate the action of ejection assembly: slide block 14 and push rod 10 can only move up and down along guide post 12 directions, because guide sliding base 13 is fixed on oblique-top sliding seat 6, along with guide sliding base 13 moving right along end needle plate, slide block 14 moves upward along its guide runner with respect to guide sliding base 13, the effect of guide post 12 is for push rod carries out secondary guiding in the motion of Z-direction, and anti-limited slip block 14 is stuck in the process of sliding along guide runner inclined-plane.
The action of sprue puller assembly: because sprue puller assembly is all arranged on slanted kicking block 1, along with slanted kicking block 1 moves along loosing core of angle ejector rod 5 directions, sprue puller assembly is motion together also, sprue puller seat 3 with respect to push rod 10 along X to moving, along with push rod 10 ejects and moves along the acceleration of Z-direction, sprue puller seat 3 and sprue puller 15 move along Z-direction with respect to slanted kicking block 1, and back-moving spring 16 is compressed, so just, by the solidifying material ejection pitched roof piece 1 in cold slug well, complete the demoulding of crotch gate materials handle.
The foregoing is only preferred embodiment of the present utility model, not in order to limit scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes.Be that simple, the equivalence that every foundation claims content of the present utility model is done changes and modify, all fall into the claim protection domain of the utility model patent.
