Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As Figure 1-3, a kind of fixture of mfg. moulding die, comprise base 100 and the mold clamping mechanism 10 of mould 101 can be clamped, described mold clamping mechanism 10 comprises the holder 11 be fixed on base 100, and the swing retaining mechanism 20 to be flexibly connected with holder 11, described holder 11 is also installed with one with swing the hydraulic traction mechanism 30 that is flexibly connected of retaining mechanism 20 and the output of hydraulic traction mechanism 30 is fixedly connected with holder 11, when hydraulic traction mechanism 30 draws swing retaining mechanism 20, swing retaining mechanism 20 toward moving near the direction of holder 11, when hydraulic traction mechanism 30 promotes to swing retaining mechanism 20, swing retaining mechanism 20 to move toward the direction away from holder 11.When mould 101 is put in mold clamping mechanism 10, it is close toward holder 11 direction that hydraulic traction mechanism 30 draws swing retaining mechanism 20, thus from mold clamping mechanism 10 clamping mold 101, because hydraulic traction mechanism 30 provides a lasting tractive force, therefore mould 101 can be continued clamping, prevent mould 101 in process medium dip or be down shifted, ensure that the precision of processing.
Hydraulic traction mechanism 30 comprises the hydraulic cylinder 31 be fixed on holder 11, and hydraulic cylinder 31 draw bar assembly 32 connects swing retaining mechanism 20.Swing retaining mechanism 20 and comprise the swing latch segment 21 two block-shaped, size is identical, two the end face connection straps 22 up and down swinging latch segment 21 are flexibly connected with holder 11.
Mold clamping mechanism 10 also comprises the dissection type drill holder assembly 40 being arranged on mold clamping mechanism 10 center, described dissection type drill holder assembly 40 comprise dismountable be arranged on holder 11 and in the first drill holder 41 of the semicolumn bodily form, also comprise dismountable be arranged on swing on latch segment 21 in 1/4 tubular second drill holder 42, when the first drill holder 41 and the second drill holder 42 surround, first drill holder 41 and the second drill holder 42 form cylindrical, the die hole suitable with mould 101 matching form is formed centrally in this cylindrical, that is, inwall and the mould 101 of the first drill holder 41 and the second drill holder 42 are fitted.
Draw bar assembly 32 also comprises the fixed head 33 be fixed on hydraulic cylinder 31, the two ends of described fixed head 33 are respectively flexibly connected a draw bar 34, described draw bar 34 is flexibly connected with swing latch segment 21 through after the towing pad 35 be arranged on holder 11, towing pad 35 runs through two opposite sidewalls of holder 11, draw bar 34 is inserted in towing pad 35, and two ends are flexibly connected fixed head 33 respectively and swing latch segment 21.Holder 11 is fixed with a withstanding tight block 13 on the sidewall of hydraulic cylinder 31, and the end winding support of the output of hydraulic cylinder 31 connects withstanding tight block 13.
Swing latch segment 21 is provided with a fastening block 23 outstanding to holder 11 direction, holder 11 is provided with one two fastening holes 12 matched with fastening block 23 shape, size, when swing latch segment 21 to holder 11 near time, fastening block 23 snaps in fastening holes 12.Therefore, when swing latch segment 21 and holder 11 near time, both can fit closely, not easily throw off, and also just improve the fastness of mold clamping mechanism 10 clamping mold 101, make mould 101 not easily break away from moulds clamp system 10.
Operation principle of the present invention is: put into by mould 101 in dissection type drill holder assembly 40, open hydraulic cylinder 31, the output of hydraulic cylinder 31 withstands holder 11, and hydraulic cylinder 31 is moved outward, and by draw bar 34 draw two swing latch segments 21 move toward holder 11 direction.The active force of hydraulic cylinder 31 is utilized first drill holder 41 and the second drill holder 42 to be surrounded and clamping mold 101, because the second drill holder 42 has two pieces and is symmetric, therefore can prevent mould 101 from tilting to both sides, also mould 101 flexural deformation is prevented, the active force of hydraulic cylinder 31 is all remained valid in whole mold pressing process, thus down drops when can prevent mould 101 from being rushed 102 punching press by instrument.
After mould 101 machines, the output of hydraulic cylinder 31 pulls hydraulic cylinder 31 to draw close to holder 11, and draw bar 34 promotes two swing latch segments 21 and moves toward away from holder 11 direction, thus unclamps mould 101.
Therefore, the present invention can avoid mould 101 mould 101 flexural deformation and scrapping and the inclination of cavity surface in extrusion process, effectively, accurately controls the extruding degree of depth, avoids the depth error caused because mould 101 is different in size.Thus improve the quality of products, enhance productivity.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ mold clamping mechanism 10, holder 11, fastening holes 12, withstanding tight block 13 herein, swing the terms such as retaining mechanism 20, swing latch segment 21, connection strap 22, fastening block 23, hydraulic traction mechanism 30, hydraulic cylinder 31, draw bar assembly 32, fixed head 33, draw bar 34, towing pad 35, dissection type drill holder assembly 40, first drill holder 41, second drill holder 42, base 100, mould 101, instrument punching 102, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
