Abstract
The utility model relates to the technical field of plastic injection molding equipment, in particular to a rotating preventing structure of a tie bar and a die locking head plate of an injection molding machine. The rotating preventing structure comprises a die locking head plate, a tie bar is arranged in the die locking head plate, one end of the die locking head plate is provided with a locking nut for locking the tie bar, one end of the tie bar is provided with a gland connected with the die locking head plate, a connecting rod is arranged between the die locking head plate and the gland, and a connecting key is arranged between the tie bar and the gland. In the utility model, the gland and the tie bar are connected through the connecting key, and the circumferential locating of the tie bar is finished. Besides, the connecting rod is located with the die locking head plate and the gland by pin holes. Therefore, circumferential stress bore by the tie bar is large, the tie bar is accurately located in the circumferential direction, and the rotating preventing performance is good.
Description
Technical field
The utility model relates to the injection-moulding plastic equipment technical field, particularly injection machine brother woods post and the anti-rotation structure of locking die plate.
Background technology
When brother woods post anti-rotation device of the prior art only leans on screw-driving, the frictional force that brother woods post and gland produce by the screw pretension prevents the rotation of brother woods post, though this structure is simple, circumferentially stressed little, be easy to occur rotating and the influence sign indicating number die face depth of parallelism at mode transfer, folding Mo Shigelin post.
At above-mentioned fault of construction, how could thoroughly solve injection molding aborning, the problem that brother woods post rotates is the problem that we inquire into research always.
Summary of the invention
The purpose of this utility model is to overcome the fault of construction that prior art exists, provide a kind of rational in infrastructure, brother woods post is circumferentially met with stresses greatly, circumferentially the location accurately prevents brother woods post injection machine brother woods post that rotates and the anti-rotation structure of locking die plate.
The purpose of this utility model is achieved in that
Injection machine brother woods post and the anti-rotation structure of locking die plate, comprise the lock die plate, be provided with brother woods post in the lock die plate, lock die plate one end is provided with the locking nut of locking brother woods post, brother woods post one end is provided with and locks the gland that die plate is connected, be provided with connecting rod between described lock die plate and the gland, key is connected between described brother woods post and the gland.
Be connected for flat key between described brother woods post and the gland.
Be connected for wedge key between described brother woods post and the gland.
Described lock die plate and gland are equipped with locating hole, and described connecting rod is located in this locating hole.
The end that described connecting rod is connected with gland is provided with nut.
The beneficial effects of the utility model are: the utility model comprises the lock die plate, be provided with brother woods post in the lock die plate, lock die plate one end is provided with the locking nut of locking brother woods post, brother woods post one end is provided with and locks the gland that die plate is connected, be provided with connecting rod between described lock die plate and the gland, key is connected between described brother woods post and the gland, and the utility model couples together gland and Ge Lin post by key, finishes the circumferential location of brother woods post.In addition, connecting rod adopts the pin-and-hole location with lock die plate and gland.Brother woods post is circumferentially met with stresses greatly, and circumferentially the location is accurate, and the anti-rotation performance is good.

7---nut.
The specific embodiment
The utility model is described in further detail with embodiment below, is not practical range of the present utility model is limited to this.
As shown in Figure 1, injection machine brother woods post and the anti-rotation structure of locking die plate, comprise lock die plate 2, be provided with brother woods post 1 in the lock die plate 2, lock die plate 2 one ends are provided with the locking nut 4 of locking brother woods post 1, one end of lock die plate 2 is provided with gland 5, is provided with connecting rod 3 between described lock die plate 2 and the gland 5, is provided with connecting key 6 between described brother woods post 1 and the gland 5 and is connected.By connecting key 6 gland 5 and Ge Lin post 1 are coupled together, finish the circumferential location of brother woods post 1.In addition, connecting rod 3 adopts the pin-and-hole location with lock die plate 2 and gland 5.Brother woods post 1 is circumferentially met with stresses greatly, and circumferentially the location is accurate, and the anti-rotation performance is good.
Wherein, be connected for flat key between described brother woods post 1 and the gland 5 or wedge key connects, also can be other connecting key 6 certainly and connect, circumferentially meet with stresses greatly as long as can guarantee brother woods post 1, circumferentially the location is accurate, and the anti-rotation performance gets final product well.
Wherein, described lock die plate 2 is equipped with locating hole with gland 5, and described connecting rod 3 is located in this locating hole, connecting rod 3 adopts the mode of this pin-and-hole location to be connected with lock die plate 2 and gland 5, brother woods post 1 is circumferentially met with stresses greatly, and circumferentially the location is accurate, and the anti-rotation performance is good.
Wherein, the end that connecting rod 3 is connected with gland 5 is provided with nut 7, and this nut 7 is for gland 5 is pressed on the brother woods post 1 closely, further guarantees gland 5 and the circumferentially reliable location of finishing of brother woods post 1.
When the utility model uses, brother woods post 1 passes lock die plate 2, with locking nut 4 lockings, finish monolateral axial restraint, by connecting key 6 brother woods post 1 and gland 5 are coupled together then, finish the circumferential Primary Location of brother woods post 1, couple together with connecting rod 3 locks die plate 2 and gland 5 again, adopt pin-and-hole to cooperate between the three, the circumferential location of finishing brother woods post 1 thoroughly prevents the rotation of brother woods post 1; With nut 7 gland 5 is pressed on the brother woods post 1 at last, finishes circumferentially reliable location.
When mode transfer, because connecting rod 3 and lock die plate 2 and gland 5 have all adopted the pin-and-hole cooperation, brother woods post 1 is connected by key 6 with gland 5, thereby the circumferential stress that brother woods post 1 can bear is big, and machine code die face depth of parallelism performance improves greatly.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
