Abstract
The present invention discloses a curve elbow mould closing mechanism on an injection machine, which comprises a fixed mould plate, a movable mould plate, a base plate, a draw rod, a mould closing cylinder and a curve elbow link mechanism, wherein one end of the draw rod is fixedly connected with the base plate, and the other end of the draw rod is fixedly connected with the movable mould plate. The curve elbow link mechanism is respectively hinged with the front supporting base of a piston rod of the mould closing cylinder and the base plate. The fixed mould plate is supported by a supporting frame and is arranged between the base plate and the movable mould plate. The draw rod is in sliding fit with the fixed mould plate. The curve elbow link mechanism is arranged between the fixed mould plate and the base plate and is hinged with the fixed mould plate. One side of the fixed mould plate is provided with a positioning frame on which the mould closing cylinder is fixed. The curve elbow mould closing mechanism needs a small calibre of the mould closing cylinder in reach the same mould locking force, and therefore, the curve elbow mould closing mechanism has low cost and short whole length. When the curve elbow mould closing mechanism is vertically arranged, an operating station is lower, inserts are suitable to inserted in the curve elbow mould closing mechanism, and a mould is not easy to be damaged.
Description
Technical field
The present invention relates to a kind of clamping of plastic-injection moulding machine, and be the clamping that is specially adapted to vertical injection molding machine.
Background technology
Traditional hydraulic lock mold mechanism only has Mode-locking oil cylinder and does not have toggle mechanism, clamp force all to be applied on the oil cylinder, thereby the cylinder seal difficulty is big, and required oil cylinder bore is bigger, the manufacturing cost height.Existing Curved Elbow Die Mechanism, as the disclosed structure of Chinese patent CN2454116Y, though the oil cylinder bore of required oil cylinder relative aperture hydraulic lock mold mechanism is little when reaching identical clamp force, but also there is following shortcoming: 1, generally only be adapted to horizontal installation, and entire length is big, and floor space is big; 2, if carry out vertical installation, then the operation position is higher, is awkward; And,, cause mould to damage as laying then easily displacement of inserts in the counterdie by the reciprocating motion of moving platen drive counterdie; 3, must be oily continually to crank connecting rod mechanism, and therefore cause the complete machine outward appearance unclean, seriously polluted.
Summary of the invention
The object of the present invention is to provide a kind ofly not only when reaching identical clamp force, required closing cylinder bore is little, and entire length is less, and not only the operation position is low but also be fit to lay the Curved Elbow Die Mechanism of inserts when vertical the installation.
The technical scheme that realizes above-mentioned purpose is: a kind of Curved Elbow Die Mechanism, have solid plate, moving platen, base plate, pull bar, closing cylinder and crank connecting rod mechanism, one end of pull bar is fixedlyed connected with base plate, crank connecting rod mechanism respectively with the preceding end bearing and the base plate hinged of the piston rod of closing cylinder, the other end of pull bar is fixedlyed connected with moving platen; Solid plate is by branching bolster supporting, and is arranged between base plate and the moving platen; Pull bar and solid plate are slidingly matched; Crank connecting rod mechanism is arranged between solid plate and the base plate, and crank connecting rod mechanism is also hinged with solid plate; One side of solid plate is provided with locating rack, and closing cylinder is fixed on the locating rack.
Further purpose of the present invention is to provide a kind of need not carry out the lubricated Curved Elbow Die Mechanism of hand oiling continually to crank connecting rod mechanism.
The technical scheme that realizes above-mentioned further purpose is when vertical installation, bearing support can be made for the fuel tank that can contain crank connecting rod mechanism.
After adopting said structure; owing to adopted closing cylinder and crank connecting rod mechanism locked mode together; thereby when reaching identical clamp force; required closing cylinder bore is little; low cost of manufacture; simultaneously; again owing to fixedlying connected with moving platen with base plate respectively in the two ends of pull bar; and solid plate by branching bolster supporting and be arranged on base plate and moving platen between; crank connecting rod mechanism is arranged between solid plate and the base plate; such structure makes pull bar; base plate; the moving platen three constitutes one; and it is reciprocating with respect to solid plate; and after closing cylinder is contained on the locating rack; because locating rack is positioned at the inboard of base plate; thereby closing cylinder is just by the plate outer side that originally was contained in Curved Elbow Die Mechanism; become and be contained on the locating rack that is positioned at the base plate inboard; this has just effectively utilized the segment space of crank connecting rod mechanism; shortened the length between solid plate and the oil cylinder bottom greatly; overcome the shortcoming that closing cylinder and crank connecting rod mechanism in the prior art are contained in the both sides of base plate respectively thereby need big installing space; the present invention has equaled to save the part or all of installation length of closing cylinder; effectively utilized the space; thereby compact conformation; entire length is less; not only can horizontally install; and vertical installation preferably, floor space is little.When vertical installation,, thereby can reduce the operation position because solid plate is in the centre position; Because counterdie is installed on solid plate, counterdie does not move, so be well suited for laying inserts, is difficult for mold damage again; Again since this moment solid plate bearing support can be arranged to Oiltank structure, thereby crank connecting rod mechanism can adopt sealing oil immersion mode, not only removed the trouble of frequent oiling in the use from, and the complete machine outward appearance of having taken on a new look, and makes it neat and tidy.
