Detailed description of the invention
Enumerating a specific embodiment below in conjunction with accompanying drawing further sets forth the present invention.
As shown in Figure 1, Figure 2, Figure 3 shows, the present invention is a kind of based on turning over structural assembly on hydraulic mechanism, comprises fluid pressure drive device, guide pillar 4, guide pin bushing 5, flange insert 7, jacking block 14, the installing plate 6 of inserting, mount pad 3.
In the present embodiment, jacking block 14 is affixed with upper mould body; Fluid pressure drive device comprises pressure transmission part 1, hydraulic cylinder 2 and pipe-line system 9, and described pipe-line system 9 links together pressure transmission part 1 and hydraulic cylinder 2; The lower surface mating reaction of the upper surface of pressure transmission part 1 and jacking block 14; The installing plate 6 of inserting is a rectangular flat structure, and four corners of the installing plate 6 of inserting all have a through hole, and on each through hole, all coupling has a guide pin bushing 5, and each guide pin bushing 5 all mates a guide pillar 4; Mount pad 3 is cubic, and four guide pillars 4 are fixed in respectively four edges of mount pad 3 upper surfaces, and the center of mount pad 3 lower surfaces has a through hole; The cylinder body of hydraulic cylinder 2 is passed the through hole of mount pad 3 by the upper surface of mount pad, the ring flange of hydraulic cylinder 2 front ends is fixed on mount pad 3, and flange insert 7 is fixed in installing plate 6 centers, upper surface of inserting; Mount pad 3 is fixed on lower mould body.
The present embodiment is also provided with four nitrogen cylinders 8, four nitrogen cylinders 8 is fixed in to mount pad 3 equably and inserts between installing plate 6; Flange insert 7 be positioned at counterdie insert 13 with insert 12 side of upper material pressing core, and be positioned at material pressing core 12 the downside of inserting.
In the present embodiment, the upper surface of the installing plate 6 of inserting is smooth smooth, and the through hole central axis of inserting on installing plate 6 is vertical with its upper surface; And the upper surface of mount pad 3 is smooth smooth, guide pillar 4 central axis on mount pad 3 are vertical with its upper surface; So just make to coordinate more accurately between guide pillar and guide pin bushing, while making package unit work, ensured the quality of product.
The shape of flange insert 7 determines by the planform of flange part, and the flange insert 7 in the present embodiment is a cylinder.
In the present invention, be also provided with sensor 11 and Pressure gauge 10, sensor 11 is connected with hydraulic cylinder 2.Sensor 11 can detect and the pressure and the state that record package unit work in real time with arranging of Pressure gauge 10, can be fine by package unit under operating personnel's manipulation in optimum state work, so just can avoid well the fault of the easy appearance in production process, ensure the crudy of the product of processing.
The course of work of the present invention is: in the time that upper die body moves downward with lower mold body matched moulds, jacking block 14 on upper die body contacts with the pressure transmission part 1 in the present invention, and pressure transmission part 1 is exerted pressure downwards, the internal pressure of pressure transmission part 1 is increased, now pressure transmission part 1 passes to pressure on the hydraulic cylinder 2 on mount pad 3 by pipe-line system 9, the piston rod of hydraulic cylinder 2 starts the installing plate 6 of inserting to apply and upward pressure, the flange insert 7 of now inserting on installing plate 6 just can to upper material pressing core insert 12 and the flange part inserted between 13 of counterdie carry out flange and processed.
Due to the guide effect of four guide pillars, make package unit offset the side force that mould produces, can ensure the proper position that fringing is inserted 7 arrival flange part to be processed.Meanwhile, insert 13 cutting edge of the cutting edge of flange insert 7 and counterdie also has guide effect, and the further like this stability of having strengthened package unit motion has been guaranteed the machining accuracy of product.
In mould applications, use this enforcement novel, can save a set of lower material pressing core and insert, even can save a whole set of upper overturning mould; Meanwhile, as long as the flange insert during this use is novel replaces to needed difform inserting, just can realize rollover, the operation such as shaping, side blow upwards, so just save manufacturing procedure, reduce cost, and applied range.
In sum, the present invention is simple in structure, compact, reasonable, has advantages of that cost is low, product percent of pass is high, applied range.
Be more than that one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the present patent application scope, within all should still belonging to patent covering scope of the present invention.
