Detailed description of the invention
With reference to accompanying drawing:
Substep die opening mechanism, comprise involutory moving platen and solid plate, moving platen is provided with mavable module core 10, and solid plate is provided with fixed mold core 1, die joint between mavable module core 10 and fixed mold core 1 is provided with the forming recess of plastic product, and described forming recess connects casting mechanism; Direction of loosing core is defined as outside, and the arranged outside of described slide block has latch segment 6, and the guide rail that described slide block is formed at slider layering slides;
It is characterized in that:
Described slide block comprises the first slide block 4, second slide block 8, and described forming recess is provided with the step stopping plastic product when die sinking is loosed core, and described step and the second slide block 8 are conflicted;
Slide block insert 2 connects the first slide block 4;
The stop screw 7 be connected on the second slide block 8 penetrates in the spacing hole on the first slide block 4; In matched moulds state, described stop screw 7 has the first spacing with the outside of spacing hole in direction of loosing core;
Described latch segment 6 connects Angle Pin 5, and Angle Pin 5 passes the second guide hole 81 on the first guide hole 41, second slide block 8 on the first slide block 4, the described bore of the first guide hole 41 and the equal diameters of Angle Pin 5; In matched moulds state, the inner side of the second described guide hole 81 flushes with the inner side of the first guide hole 41, and there is the second spacing in the outside of the second described guide hole 81 and the outside of the first guide hole 41 in die sinking direction;
The first described spacing and the second spacing, all equal slipper block loose core distance;
Perpendicular to the section of facing directly 61 in direction of loosing core on described latch segment 6, the described section of facing directly 61 is close to the second slide block 8; In die sinking process, after the described section of facing directly 61 departs from the second slide block 8, described Angle Pin 5 promotes the second slide block 8.
Further, described slide block insert 2 connects the first slide block 4 by fixed block 3.Slider layering comprises the first slider layering 11, second slider layering 12, and the first described slider layering 11 forms the guide rail of the first slide block 4, and the second described slider layering 12 forms the guide rail of the second slide block 8.
As Fig. 1, most of feature of plastic is all molded over slide block position.So need arrange novel mold mechanism at slide block position, ensure that slide block is when the demoulding, product does not follow slide block direction to move, by the demoulding of thimble pushing method.
In Fig. 2, Fig. 3,1. fixed mold core 2. slide block insert 3. fixed block 4. first slide block 5. Angle Pin 6. latch segment 7. limited screw 8. second slide block 9. plastic 10. mavable module core L1. slipper block loose core is apart from L2. die sinking apart from 11. second slider layering 12. first slide block pressure 41 first guide hole 81 second guide holes.
As Fig. 2, slide block insert 2 is connected and fixed by fixed block 3 screw and the first slide block 4.Limited screw 7 is fixed on the second slide block 8 li, and the first slide block 4 and limited screw 7 have a slipper block loose core apart from L1, has the section of facing directly 61 to be L2 die sinking distance, closely cooperate with the second slide block 8 in latch segment 6.First guide hole 41 of Angle Pin 5 and the first slide block 4 is fitted, the cross section of the second guide hole on the second slide block 8 is kidney ellipsoid hole, Angle Pin 5 and the second slide block 8 have one section of L1 Core-pulling distance, and its function is that mould first slide block 4, second slide block 8 that first slides when die sinking keeps motionless.
As shown in Figure 3, the first slide block 4 is fixed on the second slide block 8 by the first slider layering 12, and the first slide block 4 can only be slided on the second slide block 8, and the second slide block 8 is fixed on mould by the second slider layering 11.
As shown in Figure 4, limited screw 7 is arranged in the spacing hole on 4 slide blocks, and the cross section of this spacing hole is kidney ellipsoid hole, occurs L1 slipper block loose core distance in direction of loosing core.
As shown in Figure 7, in mould die sinking process, Angle Pin 5 drives the first slide block 4 in the die sinking of first stage, because slide block insert 2 and fixed block 3 and the first slide block 4 connect together, so the large slide block insert 2 of product package power is moved toward slide block direction.Produce L1 slipper block loose core distance.
Because latch segment 6 has the section of facing directly 61, in mould die sinking process, because the slanting guide pillar hole on the second slide block 8 is kidney ellipsoid hole, enough distances are had to ensure Angle Pin 5 demoulding, and the second slide block 8 keeps motionless, till generation L1 slipper block loose core distance, now slide block insert 2 departs from product, product in the second slide block 8 without package power, can the demoulding smoothly.
As shown in Figure 8, after completing first stage die sinking, mould continues die sinking, after the section of facing directly 61 of die sinking distance L2 departs from the second slide block 8 completely, by Angle Pin 5, second slide block 8 is continued die sinking, till the second slide block 8 and slide block insert 2 all depart from product, complete whole slide block stripping action.
Know-why: this slide block structure is combined by multi-slide, thinking of breaking the normal procedure, utilizes the section of facing directly 61 of novel latch segment 6 li, and slanting guide pillar hole is designed to kidney ellipsoid hole in the second slide block 8, has enough spaces to allow 5 Angle Pins move in the 28 slide block.Slide block sequence of movement first takes out the first slide block 4, ensures that the second slide block 8 is motionless simultaneously, looses core to L1 slipper block loose core distance, again by Angle Pin 5 die sinking, finally the second slide block 8 and slide block insert 2 all departed from product.
Second slide block 8 plays push pedal fixation in the slide block demoulding, first most of feature of product is retained in mavable module core 10 and the second slide block 8, first takes out the first slide block 4, then take out the second slide block 8, is successively loosed core, complete whole slide block stripping action by slide block.
Content described in this description embodiment is only enumerating the way of realization that utility model is conceived; protection domain of the present utility model should not be regarded as being only limitted to the concrete form that embodiment is stated, protection domain of the present utility model also and conceive the equivalent technologies means that can expect according to the utility model in those skilled in the art.
