Abstract
The utility model relates to a hydraulic oil cylinder with adjustable valve needle stroke, at least comprising a cylinder body, a cylinder core and a valve needle, wherein the cylinder body is provided with an internal cavity; the cylinder core is mounted in the internal cavity of the cylinder body; the valve needle is mounted at the outer end of the cylinder core; an adjustment block is in sleeved connection between the side wall of the cylinder body and the cylinder core; the periphery of the adjustment block is provided with a plurality of limiting grooves; the side wall of the cylinder body is provided with limiting holes matched with the plurality of limiting grooves; and the adjustment block is in matching connection with a steel core through a thread. By the hydraulic oil cylinder with adjustable valve needle stroke, the stroke of the valve needle can be manually adjusted according to requirements or concrete production situations, and the hydraulic oil cylinder with adjustable valve needle stroke is simple in adjustment process; and the changing on the stroke of the valve needle can be finished by manual operation of a worker.
Description
Technical field
The utility model relates to technical field of hydraulic oil cylinder, is specifically related to the adjustable hydraulic jack of a kind of needle stroke.
Technical background
Along with the development of hot runner technology, hydraulic jack needle valve type TOP-TIP is application widely.
Existing hydraulic jack needle valve type TOP-TIP mainly comprises oil cylinder, flow distribution plate, Re Zui, needle, valve seat etc.; Wherein needle closely contacts with valve seat under the effect of cylinder system, thereby reaches sealing; In long-term injection moulding 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 hydraulic jack 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 hydraulic jack, 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 hydraulic jack of a kind of needle stroke, at least comprise the cylinder body with an inner chamber, the needle that is installed on the cylinder core in the described inner chamber of cylinder block and is installed on described cylinder core outer end, also be socketed with a regulating block between described cylinder side wall and the described cylinder core, described regulating block periphery is provided with a plurality of limited impressions, and described cylinder side wall is provided with the spacing hole with described a plurality of limited impression couplings; Described adjustment piece is connected by screw-thread fit with described steel core.
The inner chamber of described cylinder body becomes cylindric.
The cross section of described adjustment piece is circular, and described a plurality of limited impressions are evenly arranged on the cross-sectional periphery of described adjustment piece.
The adjustable hydraulic jack 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, the stroke of manual tune 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 hydraulic jack structural representation of a kind of needle stroke of the utility model;
Fig. 2 is a structural representation of adjusting piece among Fig. 1.
Embodiment
Below, in conjunction with the accompanying drawings and embodiment, the adjustable hydraulic jack of needle stroke of the present utility model is described further:
Fig. 1 is the adjustable hydraulic jack of a kind of needle stroke of the present utility model, it comprises cylinder body 1, cylinder core 2, needle 6, wherein cylinder body 1 has a columned internal cavity along its length direction, and cylinder core 2 is installed in this cavity, and its needle 6 is installed in the end that cylinder core 2 is positioned at cylinder body 1 opening end; Also be socketed with one and adjust piece 3 between cylinder core 2 and cylinder body 1 sidewall, the face of its two coupling is by being threaded; In conjunction with shown in Figure 2, be provided with a plurality of limited impressions 4 in the outer peripheral edge of adjusting piece 3, wherein a plurality of limited impressions 4 are evenly arranged on the circumference of the circular cross-section of adjusting piece 3, and the angle of the center line of adjacent two limited impressions 4 equates arbitrarily; Be positioned at cylinder body 1 and be provided with spacing hole 7, spacing hole 7 passes the sidewall of cylinder body 1, with limited impression 4 conductings.
Above-mentioned hydraulic jack is in using process, in the time of need regulating the stroke of needle 6, in spacing hole 7 and groove 4, stretch into rod shape objects such as a screw rod, drive and adjust piece 3 rotations, because adjusting piece 3 and cylinder core 2 is by being threaded, therefore, when adjusting piece 3 rotations, it can realize finally that needle 6 moves up or down.
In Fig. 1, the initial stroke of needle 6 is L0, and when adjustment piece 3 moved up L1, the stroke of needle 6 then became L0-L1 by L0; When adjustment piece 3 moved down L2, the stroke of needle 6 then became L0+L2 by L0; This shows that the stroke of needle 6 of the present utility model can change between the L0-L1 to L0+L2 by the shirtsleeve operation manual adjustment under the situation that does not change original accessory.
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.
