Abstract
The invention relates to a crosshead structure of a mold-locking device of a toggle rod type injection molding machine. The mold-locking device of the toggle rod type injection molding machine is formed by matching a novel crosshead with a mold-locking oil cylinder, a rear mold plate, a hook hinge, a long hinge, a small hinge, a movable mold plate, and a pull rod. The crosshead is fixed on a piston rod of the mold-locking oil cylinder and the pull rod; the hook hinge and the long hinge are respectively connected with suspension arms on the rear mold plate and the movable mold plate; the crosshead is formed by connecting the small hinge and the hook hinge. The crosshead structure is simple; the manufacturability and materials of the rear mold plate can be saved; by adopting reinforcing ribs, the rigidity and the strength of the crosshead structure are improved; meanwhile, the breaking of the rear mold plate near an A-shaped frame due to non-balanced stress on the rear mold plate caused by the conventional crosshead structure form during mold opening and closing is avoided. The mold-locking device is convenient to process and install, and steadily moves.
Description
Technical field
The present invention relates to a kind of clamping apparatus of toggle rod type injection machine, especially a kind of cross head design of clamping apparatus of toggle rod type injection machine.
Background technology
The clamping apparatus of existing toggle rod type injection machine uses two groups of elbow-bar mechanism, connects with crosshead between the elbow-bar mechanism, and crosshead is driven by Mode-locking oil cylinder, and slide at two guide posts, in the course of the work, for fear of stuck, elbow-bar mechanism and crosshead must high accuracy processing and assemblings.Because the Mode-locking oil cylinder of above-mentioned conventional apparatus is used for crosshead with masterpiece, crosshead is delivered on the moving platen after by toggle link power being amplified, so in motion process, especially at die sinking extreme position or front rod during near the upright position, it is very serious to wear and tear, and can cause mechanical performance to descend, simultaneously because the crosshead bumpy motion, the radial load of Mode-locking oil cylinder effect acts on rear pattern plate by two cross-head guide bars, causes the fracture of rear pattern plate " A " cabinet frame place.
Known Chinese patent ZL200520132386.8 " a kind of clamping apparatus of special-purpose injection machine ", improve folding by optimization machine strand parameter and imitate rate, but still there are serious wear, a bumpy motion of traditional toggle rod type injection machine, rear pattern plate " A " cabinet frame place phenomenon of rupture.
Summary of the invention
At the deficiency that prior art exists, the object of the present invention is to provide a kind of clamping apparatus of toggle rod type injection machine simple in structure.
For achieving the above object, the present invention is by the following technical solutions:
A kind of clamping apparatus of toggle rod type injection machine, comprise a rear pattern plate, a moving platen, a front template, four pull bars, a Mode-locking oil cylinder, two elbow-bar mechanism and crossheads, crosshead is fixed on the piston rod of Mode-locking oil cylinder, crosshead comprises the main body that connects with piston rod, it is characterized in that: main body is provided with four engaging lugs that extend to pull bar, offer a pilot hole that can pass for corresponding pull bar on each engaging lug, crosshead is enclosed within on four pull bars slippingly by these four pilot holes.
Technique scheme can also be further improved by following technical measures:
Be the hank joint chair between first engaging lug and second engaging lug, be another hinge joint seat between the 3rd engaging lug and the 4th engaging lug, stride between the second engaging lug stage casing and the 3rd engaging lug stage casing and be provided with reinforcement, stride between the 4th engaging lug stage casing and the first engaging lug stage casing and be provided with reinforcement.
Be provided with axle sleeve between pilot hole and the pull bar.
Cross head design of the present invention adopts reinforcement to improve its rigidity and intensity, four pilot holes are fixed on the pull bar (also being guide pillar or brother woods post), pull bar plays cross-head guide and bearing radial force effect, its motion is more steady, thereby does not need " A " cabinet frame and the guide post of traditional locks die device rear pattern plate.Compare with the clamping apparatus of traditional toggle rod type injection machine, the structure optimization of locked mode rear pattern plate, motion steadily cause its " A " cabinet frame phenomenon of rupture when solving locked mode.Though the weight of crosshead need have increase simultaneously, " A " cabinet frame cancellation of tailgate, overall weight reduces, the manufacturability of tailgate, reliability gets a promotion, two parts such as crosshead guide bar cancellations, manufacturing cost also is reduced.

The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in the figure, a kind of clamping apparatus of toggle rod type injection machine, comprise a rear pattern plate 2, one moving platen 14, one front template 17, four pull bars 15, one Mode-locking oil cylinder 1, two elbow-bar mechanism and a crosshead 7, crosshead 7 is fixed on the piston rod 6 of Mode-locking oil cylinder 1, crosshead 7 comprises the main body 7-5 that connects with piston rod 7, main body 7-1 is provided with four engaging lug 7-1 that extend to pull bar, 7-2,7-3,7-4, offer a pilot hole 7-6 that can pass for corresponding pull bar 15 on each engaging lug, crosshead 7 is enclosed within on four pull bars 15 slippingly by these four pilot hole 7-6.
Be hank joint chair 7-7 between first engaging lug 7-1 and second the engaging lug 7-2, be another hinge joint seat 7-8 between the 3rd engaging lug 7-3 and the 4th the engaging lug 7-4, stride between the second engaging lug 7-2 stage casing and the 3rd engaging lug 7-3 stage casing to be provided with to stride between reinforcement 18, the four engaging lug 7-4 stage casings and the first engaging lug 7-1 stage casing and be provided with reinforcement 18.Two reinforcements, 18 left-right symmetry.Reinforcement, engaging lug, hinge joint seat and main body are an integral body.
Elbow-bar mechanism comprises rap 8, hook strand 5 and long strand 11.Two hinge joint seats of crosshead 7 are connected with hook strand 5 by rap 8 respectively.
Mode-locking oil cylinder 1 is installed on the rear pattern plate 2 by screw, and its piston rod 6 front ends are connected with crosshead 7.
During die sinking, Mode-locking oil cylinder 1 drives crosshead 7 by piston rod 6, its four pilot holes pass pull bar 15 guiding, rap 6 makes long strand 11 rotate along bearing pin 4 clockwise directions, and moves down, and drives long strand 11 by bearing pin 12 and draws in downwards, thereby pulling moving platen 14 is moved to the left, mould is thrown off, if mobile for matched moulds, with above-mentioned round about.
Patent of the present invention is compared with prior art: cross head design adopts reinforcement to improve its rigidity and intensity, four pilot holes are fixed on the guide pillar, guide pillar plays cross-head guide and bearing radial force effect, its motion is more steady, thereby does not need " A " cabinet frame and the guide post of traditional locks die device rear pattern plate.The structure optimization of locked mode rear pattern plate, motion steadily, " A " cabinet frame phenomenon of rupture that causes it when solving locked mode, though the weight of crosshead need have increase simultaneously, " A " cabinet frame cancellation of tailgate, overall weight reduces, the manufacturability of tailgate, reliability gets a promotion, two parts such as crosshead guide bar cancellations, and manufacturing cost also is reduced.
The above act executed example and only is used for conveniently illustrating patent of the present invention, is not that patent of the present invention is done any pro forma restriction, and every equivalent transformation or modification of making according to the design concept among the present invention all should be thought to fall into protection scope of the present invention.
