Abstract
The invention provides an injection shifting cylinder of an injection molding machine. The injection shifting cylinder of the injection molding machine comprises a piston and a piston rod. The piston is provided with a groove. A plane of the groove is mutually perpendicular to the piston rod. One end of the piston rod penetrates into the groove to fit with the piston. The end of the piston is provided with a threaded hole parallel to an axis of the piston. A screw is tightened into the piston through the threaded hole, and the head of the screw is screwed into one end of the piston rod, which matches with the piston, so that the piston is fixedly connected with the piston rod. A first seal ring is arranged between the piston and the piston rod. The other end of the piston rod is fixedly connected with a connecting rod through a nut. The groove of the piston matches with the piston rod, and the inner wall of the groove surrounds one end of the piston rod to position the piston rod. In addition, the seal ring is arranged between the piston and the piston rod for sealing.
Description
Technical field
The present invention relates to a kind of injection machine accessory, relate in particular to penetrating of a kind of injection machine and move oil cylinder.
Background technique
Mould is the indispensable part of product manufacturing industry, and the quality of a secondary mold design directly has influence on the quality of product.At present injection machine is used more frequent, and used the penetrating of present injection machine move the oil cylinder that oil cylinder is half piston rod mostly, penetrates the speed that injects of moving oil cylinder and is starkly lower than and penetrates the back speed degree; It all is to realize through fastening screw trip bolt and locating stud that piston was located with being connected of piston rod; In use fastening screw trip bolt is easy to become flexible, and overhaul constantly at any time and change, and influences manufacturing efficiency; Also can damage equipment when serious, and locate the inaccurate operation that can influence entire equipment.
In view of this, be necessary that penetrating of injection machine in the existing technology moved oil cylinder improves, to address the above problem.
Summary of the invention
The object of the present invention is to provide penetrating of a kind of injection machine to move oil cylinder.
For realizing the foregoing invention purpose, the invention provides penetrating of a kind of injection machine and move oil cylinder, comprise piston and piston rod; Said piston is provided with groove, and groove belongs to the plane and said piston rod is orthogonal, and said piston rod one end is deep in the said groove and cooperates with said piston; Said pistons end has tapped hole; Tapped hole is parallel with said piston axis, and screw screws in piston through said tapped hole and screw head screws in the end that said piston rod cooperates with said piston, and said piston is fixedly connected with piston rod; Be provided with first seal ring between said piston and the piston rod, the other end of said piston rod is fixedly connected through nut with extension bar.
As further improvement of the present invention; Said penetrating moved oil cylinder and also comprised penetrating and move cylinder and pass through lid; Said penetrating moved cylinder and passed through lid and be set on the said piston rod and with said piston and contact, and said penetrating moved cylinder and passed through and be provided with dust ring, oilite bushing, second seal ring, retaining between lid and the said piston rod successively and fill up and back-up ring.
Compared with prior art; The invention has the beneficial effects as follows: the present invention cooperates with piston rod through groove is set on piston, and the groove inwall is centered around the location that piston rod one end has been realized piston rod, in addition; Be provided with seal ring between piston and the piston rod, reached the purpose of sealing.
Description of drawings
