Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 3, wherein product 10 inner side the right and left of upper surface there is upside left barb 11, the right barb 12 in upside respectively, also there is inside its lower surface downside barb 13.Existing oblique core-pulling die generally all can only once tiltedly be loosed core, and cannot complete the production of this product 10.
Refer to Fig. 1-3, a kind of oblique core-pulling die of secondary of automatic lock core, comprise upper mounted plate 100 from top to bottom successively, have the caster 200 of mother module core 210, have the male template 300 of male die core 310, ejector retainner plate 400 and bottom plate 500, the oblique core-pulling die of secondary of described automatic lock core also comprises master mold push pedal 220, oil hydraulic cylinder 230, spring 110, deduction and lock core mechanism, described master mold push pedal 220 is slided and is arranged between upper mounted plate 100 and caster 200, and master mold push pedal 220 vertically slides up and down, the left and right sides of described master mold push pedal 220 is connected to the first taper pin 221, first taper pin 221 is slidably mounted in master mold push pedal 220, and the first taper pin 221 horizontally slips in the horizontal direction, first taper pin 221 runs through caster 200 and mother module core 210 obliquely and inserts in mold cavity, caster 200 is provided with first slider guide 222 corresponding with the first taper pin 221, in master mold push pedal 220, two the first taper pins 221 of the left and right sides are respectively used to exit the right barb 12 of left barb 11 and upside on the upside of product 10, described oil hydraulic cylinder 230 is fixedly arranged on caster 200, its piston rod 231 is connected to master mold push pedal 220, described lock core mechanism is by lock core oil cylinder 600, lock core head 610 and lock core cover 620 composition, lock core oil cylinder 600 is fixedly arranged on caster 200, and the telescopic direction of the telescopic direction of lock core oil cylinder 600 and oil hydraulic cylinder 230 is perpendicular, lock core head 610 is installed in the expansion link end of lock core oil cylinder 600, lock core cover 620 is set on the piston rod 231 of oil hydraulic cylinder 230, and lock core overlaps 620, and position is corresponding in the horizontal direction with lock core head 610, lock core cover 620 offers the groove corresponding with lock core head 610, when lock core oil cylinder 600 extends, lock core head 610 is inserted in the groove of lock core cover 620 just, thus the piston rod 231 of oil hydraulic cylinder 230 is fixed, it is made to move, reach the object of lock core, described spring 110 is fixedly arranged on upper mounted plate 100, its plunger rod 111 pushes against the upper surface of described caster 200 downwards, preferably, described spring 110 is nitrogen spring, and suppressing of nitrogen spring is large, its pressure in stroke keeps substantially constant, take up room little, precompressed amount is little, long service life, safe and reliable, save cost, described deduction comprises the locking bed 320 be fixedly arranged in male template 300 and the hooked latch 120 be fixedly arranged on upper mounted plate 100, and described hooked latch 120 is vertically slided and inserted in locking bed 320, described ejector retainner plate 400 slidably connects the second taper pin 410, and the second taper pin 410 horizontally slips in the horizontal direction, described second taper pin 410 runs through male template 300 and male die core 310 obliquely and inserts in mold cavity, described male template 300 is provided with second slider guide 411 corresponding with the second taper pin 410.
Operation principle of the present invention is: in process, and lock core oil cylinder 600 extends, and lock core head 610 is inserted in the groove of lock core cover 620 just, thus the piston rod 231 of oil hydraulic cylinder 230 is fixed, make it move, reach the object of lock core, avoid making because pressure is comparatively large latch displacement of loosing core in process.During first time die sinking, machine drives male template 300 and bottom plate 500 to move downward, under the plunger rod 111 of spring 110 ejects effect downwards, upper mounted plate 100 is first separated with caster 200, caster 200 moves downward along with male template 300 simultaneously, master mold push pedal 220 synchronously moves downward along with caster 200, until the hooked latch 120 of described deduction fastens described locking bed 320, and caster 200 and master mold push pedal 220 stop motion.During second time die sinking, lock core oil cylinder 600 shrinks, the groove that lock core head 610 and lock core overlap 620 departs from, thus the piston rod 231 of oil hydraulic cylinder 230 is unlocked, male template 300 and bottom plate 500 continue to move downward, caster 200 separates with male template 300, meanwhile, the piston rod 231 of oil hydraulic cylinder 230 is replied downwards and is pulled master mold push pedal 220 to move downward, first taper pin 221 to slide the left barb 11 in upside exited inside product 10 upper surface to die inside under the promotion of the first slider guide 222, the right barb 12 in upside, then the top rod of mould upwards ejects, promote ejector retainner plate 400 to move upward, second taper pin 410 exits the downside barb 13 of product 10 lower surface under the effect of the second slider guide 411 to product inner slide, thimble simultaneously on ejector retainner plate 400 is by product 10 ejection device.
The oblique core-pulling die of secondary of described automatic lock core can carry out secondary and tiltedly loose core, and can be used for producing upper and lower two inner side surfaces and all has barb and the less plastic cement products of structure; The oblique core-pulling die of secondary of described automatic lock core can make up the deficiency of hydraulic pressure self-lock force by lock core mechanism, make positioning stablity of loosing core, and avoids affecting shaping high-quality because loosing core displacement in process.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
