Technical Field
The utility model relates to a screw rod technical field of moulding plastics specifically indicates an injection molding screw rod for injection molding machine.
Background
The injection molding machine screw rod is the important part of injection molding machine, and mainly used carries, the compaction to plastics, melts, stirs and exerts pressure, and the screw rod of current moulding plastics is the integrated into one piece structure usually, is fixed together between transfer line and the helical blade, can't carry out solitary dismantlement separation, when needs use different helical blade, needs the hob of the model of whole renewal, and it is comparatively troublesome to change, and it is not nimble convenient enough to use, and adaptability is relatively poor.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome above technical defect, provide an injection molding screw rod for injection molding machine, conveying part and bull stick can the alternate segregation, and it is convenient to change, and it is nimble convenient to use, and adaptability is stronger.
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides an injection molding screw rod for injection molding machine, includes the bull stick, the one end of bull stick is equipped with the connecting rod, it has the keyway to open on the connecting rod, the one end that the bull stick is close to the connecting rod is equipped with the baffle, be equipped with the guide slot of being no less than one on the bull stick, be equipped with conveying part on the bull stick, conveying part includes the sleeve of being connected with the bull stick grafting, be equipped with on the telescopic inner wall with guide slot complex gib, be equipped with helical blade on the telescopic outer wall, telescopic one end is equipped with the screw hole one of being no less than one, be equipped with the screw hole two that corresponds with screw hole one on the baffle, the one end threaded connection that the baffle was kept away from to the bull stick has and sleeve complex fixed separation blade.
Compared with the prior art, the utility model the advantage lie in: one end is spacing through the baffle between transport portion and the bull stick and is passed through screw fixed connection simultaneously, and the other end is fixed through fixed separation blade to realize the connection of dismantling between transport portion and the bull stick, when the helical blade of different requirements is changed to needs like this, only need solitary change transport portion just, need not change together with the pivot, comparatively convenient and fast uses nimble convenience simultaneously, and adaptability is stronger.
As the improvement, the guide slot is equipped with four, and even distribution improves the stability of being connected between sleeve and the pivot on the week outer wall of bull stick.
As the improvement, baffle, connecting rod and bull stick are integrated into one piece structure, improve holistic stability.
As the improvement, be welded connection between sleeve and the helical blade, and the welding department is through polishing treatment, connects comparatively conveniently, firm.
As the improvement, sleeve and conducting bar are integrated into one piece structure, and overall stability is better.
