The specific embodiment
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, the mold clamping mechanism 10 that comprises base 100 and can clamp mould 101, described mold clamping mechanism 10 comprises the holder 11 being fixed on base 100, and the swing retaining mechanism 20 being flexibly connected with holder 11, on described holder 11, be also installed with a hydraulic traction mechanism 30 being flexibly connected with swing retaining mechanism 20 and the output of hydraulic traction mechanism 30 and be fixedly connected with holder 11, when hydraulic traction mechanism 30 tractions swing retaining mechanism 20, swing retaining mechanism 20 toward the direction motion near holder 11, when hydraulic traction mechanism 30 promotes to swing retaining mechanism 20, swing retaining mechanism 20 toward the direction motion away from holder 11.When mould 101 is put in mold clamping mechanism 10, it is close toward holder 11 directions that hydraulic traction mechanism 30 tractions swing retaining mechanism 20, thereby from mold clamping mechanism 10 clamping molds 101, because hydraulic traction mechanism 30 provides a lasting tractive force, therefore mould 101 can be continued to clamp, prevent that mould 101 from, in process medium dip or down displacement, having guaranteed the precision of processing.
Hydraulic traction mechanism 30 comprises the hydraulic cylinder 31 being fixed on holder 11, and hydraulic cylinder 31 use draw bar assemblies 32 connect swing retaining mechanism 20.Swing retaining mechanism 20 and comprise two block-shaped, big or small identical swing latch segments 21, two end faces up and down that swing latch segment 21 are flexibly connected with holder 11 with connection strap 22.
Mold clamping mechanism 10 also comprises the dissection type drill holder assembly 40 that is arranged on mold clamping mechanism 10 centers, described dissection type drill holder assembly 40 comprises dismountable the first drill holder 41 on holder 11 and that be the semicolumn bodily form that is arranged on, also comprise dismountable 1/4 tubular the second drill holder 42 that is swinging on latch segment 21 that is arranged on, when the first drill holder 41 and the second drill holder 42 surround, the first drill holder 41 and the second drill holder 42 form cylindrical, in this cylindrical, be formed centrally the die hole matching with mould 101 shapes, that is to say, the inwall of the first drill holder 41 and the second drill holder 42 and mould 101 laminatings.
Draw bar assembly 32 also comprises the fixed head 33 being 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 after passing the towing pad 35 being arranged on holder 11, towing pad 35 runs through opposed two sidewalls of holder 11, draw bar 34 is inserted in towing pad 35, and two ends are flexibly connected respectively fixed head 33 and swing latch segment 21.On the sidewall of holder 11 near hydraulic cylinder 31, be fixed with a withstanding tight block 13, the end of the output of hydraulic cylinder 31 is fixedly connected with withstanding tight block 13.
Swing latch segment 21 and be provided with one to the outstanding fastening piece 23 of holder 11 directions, holder 11 is provided with one two the fastening holes 12 that match with fastening piece 23 shapes, size, when swing latch segment 21 to holder 11 near time, fastening piece 23 snaps in fastening hole 12.Therefore, when swing latch segment 21 and holder 11 near time, both can fit closely, are difficult for throwing off, and have also just improved the fastness of mold clamping mechanism 10 clamping molds 101, make mould 101 be difficult for break away from moulds clamp mechanism 10.
Operation principle of the present invention is: mould 101 is put 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 moves toward holder 11 directions by two swing latch segments 21 of draw bar 34 traction.Utilize the active force of hydraulic cylinder 31 the 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 and be symmetric, therefore can prevent that mould 101 from tilting to both sides, also prevent mould 101 flexural deformations, the active force of hydraulic cylinder 31 is all remained valid in whole Mould Machining process, thereby can prevent from when mould 101 from being rushed 102 punching press by instrument down dropping.
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 and swings latch segment 21 toward moving away from holder 11 directions, thereby unclamps mould 101.
Therefore, the present invention can avoid mould 101 mould 101 flexural deformations and scrapping and the inclination of cavity surface in extrusion process, effectively, accurately controls the extruding degree of depth, avoids because of mould 101 depth error causing different in size.Thereby 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 modifications or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although more used mold clamping mechanism 10, holder 11, fastening hole 12, withstanding tight block 13 herein, swung the terms such as retaining mechanism 20, swing latch segment 21, connection strap 22, fastening piece 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, the first drill holder 41, the second drill holder 42, base 100, mould 101, instrument punching 102, do not got rid of the possibility of using other term.Use these terms to be only used to describe more easily and explain essence of the present invention; They are construed to any additional restriction is all contrary with spirit of the present invention.
