Abstract
The utility model discloses a mould locking mechanism. A mould moving guide rail pair can cause two mould locking devices to move towards each other, and the locking of hinged arm connecting seats is realized through a mould locking guide rail pair. The locking or separating of the two hinged arm connecting seats is realized by using a mould locking oil cylinder as power driven and a hinged arm as transmission, and the synchronous movement of the two hinged arm connecting seats is realized through a synchronous gear device. In addition, an anti-collision frame and an anti-collision block are additionally arranged on the mould locking mechanism, so the safety of the mould locking mechanism is ensured during working. By the mechanics principle and the action of the guide rail pairs, the mould locking mechanism ensures that the stress center point of a template on a locking arm connecting seat acting on a mould is not changed; even if a large mould is clamped, the template is not easily deformed, and the guide rail pairs and corresponding sliding blocks are not easily worn; the locking force of mould locking connecting seats can be greatly increased by adopting hinged arm locking, and the mould locking force is enough; meanwhile, by the assist of the synchronous gear device, the synchronous movement and the synchronous locking of the two mould locking connecting seats are realized; and the quality of product is greatly ensured.
Description
Technical field
The utility model relates to a kind of clamping mechanism, relates in particular to the clamping mechanism that a kind of mode with pivoted arm realizes clamp force.
Background technology
At present, the large size plastic jetting-moulding device that injection machine manufacturer in countries in the world produces, the version of its mode locking unit can reduce three kinds of forms substantially: (1) mechanical lock mode structure; (2) two plates four oil cylinder booster-type mould-locking structures; (3) two plate list oil cylinder vertical compression type mould-locking structures.
The mould-locking structure of three kinds of forms; pluses and minuses are respectively arranged; now briefly be compared as follows: 1. the mechanical lock mold mechanism is by forming advantage by locked mode plate, locked mode toggle, cylinder drive etc.: mechanism is reliable, movement velocity is fast, cost is low, hydraulic system is simple, low energy consumption etc.Shortcoming is: the clamp force of setting during easily by the variations in temperature of system motion heating and environment the pull bar elongation cause clamp force loss, and strong mechanical friction arranged under heavy load, the intrinsic running precision that causes machine is after the use of a period of time, just be subjected to bigger influence, relative maintenance cost is also higher.
2. two plates, four oil cylinder booster-type mould-locking structures, advantage: no matter be to adopt rotary be connected or cohesion style connects between brother woods post and the high-voltage lock mould oil cylinder piston (A), under die opening state, brother woods post all can break away from solid plate.Therefore, can realize the operation of side progressive die.Having reduced the requirement to factory building height virtually, is a very desirable advantage.(B) mould structure is simple, so comparatively speaking, the overall weight of locked mode portion cover is low weight, and transportation, lifting are conveniently.(C) demoulding ejecting mechanism is installed on the back side of moving platen, and the space is not subjected to any restriction, installs, dismantles, keeps in repair all more convenient.(D) structure is simple relatively, so cost is also cheap relatively.Shortcoming: (A) profile of four oil cylinders is because of being subject to platen size, and can not do very greatly, and can effectively produce the endless belt area that is only limited to four oil cylinder pistons of clamp force.For the effective area of single cylinder structure, this effective area is big inadequately.In order to reach specified clamp force, have only high-voltage lock mould pressure is pressurized to 280-320kg/cm2, even 350kg/cm2.This just has quite harsh requirement to the quality of form and position tolerance, surface smoothness, total quality and the seal of cylinder body.And the level of current Chinese manufacturing generally is difficult to reach this requirement.Two plates, four oil cylinder booster-type locked mode large size plastic jetting-moulding devices are produced in the native land, ubiquity high pressure leakage of oil problem, and can't thoroughly solve.This is a big deadly defect of this structure.(B) for adopting the four cylinder mould-locking structures that are rotatably connected between brother woods post and the solid plate high-voltage lock mould oil cylinder, be buckled with and imitate area and reduce by half owing to bear the spiral shell of clamp force, pressure is too big, causes the spiral shell button surrender brother woods post head fracture even of breaking easily.This case is of common occurrence.(C) change the molar space, must realize by mould adjusting mechanism.This is a weak point for the hydraulic pressure locking injection machine.
3. two plate list oil cylinder vertical compression type mould-locking structures, advantage: (A) moving platen is not by brother woods post guiding, the depth of parallelism between head, two sign indicating number die faces of two plates can arbitrarily be adjusted within the specific limits, therefore is adjustable to the degree that is bordering on absolute parallel, helps precision moding.(B) the line journey of unblanking is not subjected to structural restriction, can strengthen its line journey of unblanking according to technologic needs.This is a hydraulic pressure locking injection machine biggest advantage, also is the topmost weakness of toggle formula machinery locking injection machine.(C) do not need mould adjusting mechanism, by means of the sensing technology of precision, in whole molar spatial dimension, can locate voluntarily fast, the nut obvolvent, play high-voltage lock mould.Everything is continuous, accurate, brisk, promptly carry out.Shortcoming: (A) because of its moving platen is to adopt composite structure, so comparatively speaking, the overall weight of locked mode portion cover is heavier, and it is not too convenient to transport, lift.(B) fixedly connected because of adopting between four Gen Gelin posts and the solid plate, thus can not allow one or more brother woods posts break away from solid plates, and realize the operation of side progressive die.(C) complicated because of clamping mechanism, the manufacture process requirement height is so cost is higher.
At above-mentioned existing situation, although the shortcoming of existing mechanical clamping mechanism can overcome with all-hydraulic clamping mechanism, the advantage of existing mechanical clamping mechanism is again that all-hydraulic clamping mechanism is unapproachable.The applicant endeavours the research and development to the clamping mechanism of existing situation always, has improved out a kind of clamping mechanism that can overcome existing machinery clamping mechanism shortcoming finally.
