A kind of support oriented device of injection machine injection member
Technical field
The utility model relates to the support oriented device on a kind of injection machine, especially relates to a kind of support oriented device of injection machine injection member.
Background technology
The support oriented device of traditional injection moulding machine injection member comprises preceding supporting seat, back supporting seat and guide post, and the guiding bridge is between preceding supporting seat and back supporting seat, and preceding supporting seat is positioned at the front end of guide post, and back supporting seat is positioned at the rear end of guide post.The injection machine injection member comprises parts such as injection header board and injection back plate; The injection header board is bearing in the leading portion part of guide post and can on guide post, moves; Injection back plate is bearing in the back segment part of guide post and can on guide post, moves; Fairlead between injection header board or injection back plate and the guide post adopts the full circle shape, in order to make injection member moving on guide post, must make between fairlead and the guide post of full circle shape to have relatively large fit clearance.
There is following problem in the support oriented device of said structure: 1. have relatively large fit clearance between fairlead and the guide post, the fore-end that can make injection member is owing to the sagging deflection of gravity effect, and this can influence injection-molded product.2. because injection member is in frequent mobile status when work, can cause the fairlead wearing and tearing, the fairlead after the wearing and tearing is changed cumbersome, and the dismounting of injection member is cumbersome simultaneously.3. the front and back supporting seat is positioned at the two ends of guide post, the weight supporting of whole injection member on guide post and long-time frequent action of injection can cause the guide post distortion, this can influence injection-molded product.
Summary of the invention
The utility model technical problem to be solved provides a kind of support oriented device of avoiding the injection machine injection member of the sagging distortion of injection member.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of support oriented device of injection machine injection member; Comprise preceding supporting seat, back supporting seat and guide post; Described guiding bridge before described supporting seat with the back supporting seat on; Injection member is clamped on the guide post through clamping device; Described clamping device comprises semi-circular base frame that is fixed under the injection member and the semicircle clamping seats that is positioned at the guide post below, and described semicircle clamping seats is fixed on the described semi-circular base frame through first screw, is provided with two semicircle fairleads between described clamping device and the described guide post.
Described two semicircle fairleads comprise the first semicircle fairlead and the second semicircle fairlead; The first semicircle fairlead is fixed on the semi-circular base frame inwall through second screw, and the second semicircle fairlead is fixed on the semicircle clamping seats inwall through the 3rd screw.
Described clamping device is installed in the injection header board below of injection member; Supporting seat is positioned at the front end of guide post before described; Described back supporting seat has a segment distance apart from the guide post rear end; Described back supporting seat is positioned at plate below, injection back, is provided with the 3rd semicircle fairlead between semi-circular base frame under the plate of injection back and the guide post, and the described the 3rd semicircle fairlead is fixed on the semi-circular base frame inwall through the 3rd screw.
Compared with prior art, the utility model has the advantages that with clamping device to clamp guide post, can reduce the fit clearance between circular fairlead and the guide post, thereby reduce injection member greatly because the sagging deflection that the gravity effect causes.The dismounting of injection member is more convenient simultaneously.
After the fairlead wearing and tearing, can regulate the fit clearance between fairlead and the guide post, after fairlead heavy wear, change also more convenient simultaneously through screw.
The reach of the position of back supporting seat is avoided guide post because the injection member frequently distortion that causes of action of injection and injection member weight for a long time.
