Abstract
The utility model discloses a gas cylinder with adjustable valve needle travel, which at least comprises a cylinder body component with an inner cavity, a cylinder core with an axial through hole and positioned in the inner cavity of the cylinder body component, and a valve needle component sleeved in the axial through hole of the cylinder core, wherein an adjusting block is sleeved between the valve needle component and the cylinder core, the valve needle component is fixedly connected with the adjusting block which is in fit connection with the cylinder core through a thread. Thus the valve needle travel can be adjusted according to the requirement or the specific production status; and the adjusting process is simple so that the valve needle travel can be shifted only by manual operations of staffs.
Description
Technical field
The utility model relates to the cylinder technical field, is specifically related to the adjustable cylinder of a kind of needle stroke.
Technical background
Along with the development of hot runner technology, cylinder valve pin type TOP-TIP is application widely.
Existing cylinder is in long-term injection moulding using process, needle is frequently opened and the excessive wear or the sealing face of damage, cause sealing not tight, phenomenons such as strike-through or leakage glue appear, the effective way of energy head it off is the needle that more renews again, so way has increased cost beyond doubt, if the new sealing face of processing will cause needle too short on former needle basis.In addition, in course of working or assembly process, for various reasons, also may there be the long or too short situation of needle sometimes.
To sum up, develop and a kind ofly can regulate the cylinder of needle length, become the focus of paying close attention in the industry according to concrete PRODUCTION STATUS.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of needle stroke adjustable cylinder, and its needle can be reconciled its length as required, to be adapted to different production status.
For achieving the above object, the utility model adopts following technological scheme:
The adjustable cylinder of a kind of needle stroke, at least comprise housing assembly with an inner chamber, be positioned at the cylinder core that described housing assembly inner chamber has an axial hole, be socketed on the needle assembly of described cylinder mandrel in through hole, also be socketed with one between described needle assembly and the described cylinder core and adjust piece, described needle assembly is fixedlyed connected with described adjustment piece, and described adjustment piece and described cylinder core are connected by thread.
Described needle assembly comprises stud bolt and needle, and described stud bolt outer peripheral edge is provided with the screw thread with described adjustment piece through-hole wall coupling.
Described housing assembly comprises cylinder body, and the cylinder body lid that is connected in cylinder body one end.
Also be provided with suction port and air outlet on the described cylinder body with the conducting of described housing assembly inner chamber.
The adjustable cylinder of the needle stroke that the utility model is set forth, its beneficial effect is:
1, it can be as required or concrete PRODUCTION STATUS, regulates the stroke of needle;
2, adjustment process is simple, and producers' manually-operable can be finished the conversion to needle stroke.
Description of drawings
Fig. 1 is the adjustable structural representation of air cylinder of a kind of needle stroke of the utility model;
Fig. 2 is cylinder core shown in Figure 1 and the connection diagram of adjusting piece.
Embodiment
Below, in conjunction with the accompanying drawings and embodiment, the adjustable cylinder of needle stroke of the present utility model is described further:
Fig. 1,2 is the adjustable cylinder of a kind of needle stroke of the present utility model, it comprises cylinder body 3, cylinder cap 1, wherein cylinder cap 1 is fixedly connected on the upper end portion of cylinder body 3, after its two connection, form one along the ccontaining longitudinally cavity of cylinder body 1, in this cavity, cylinder core 2 is installed longitudinally, cylinder core 2 be vertically arranged with a through hole, be equipped with one in this through hole and adjust piece 5, adjust piece 5 and be provided with a vertical hole along its length direction, in this vertical hole, the needle assembly is installed, the needle assembly comprises the stud bolt 6 that is positioned at its top, and the needle 4 that is fixedly installed in stud bolt 5 bottoms, wherein adjusts the screw threads that vertically inwall in hole is provided with and mate stud bolt 6 outsides on the piece 5, thereby stud bolt 6 is installed in needle 4 and adjusts on the piece 5.Adjusting the outer surface of piece 5 and the inwall of cylinder core 2 through holes is connected by thread 7.
In the adjustable cylinder using process of above-mentioned needle stroke, when need regulating its stroke, cooperates with thread 7, then can regulate the relative displacement of adjusting piece 5 and cylinder core 2, with the stroke of change needle 4 owing to adjust between piece 5 and the cylinder core 2; When adjustment piece 5 moves up, d will become greatly among Fig. 2, and promptly the stroke of needle 4 becomes big before; When adjustment piece 5 moves down, d will diminish, and promptly the stroke of needle 4 diminishes before.
In the utility model, inventor's cylinder cap and cylinder body are set to detachable structure, so that repair demolition and installation; In addition, as shown in Figure 1,, also be provided with suction port 8 and air outlet 9 with the conducting of housing assembly inner chamber at cylinder body 3 sidewalls.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technological scheme described above and design.
