Abstract
The utility model relates to a single-point needle valve type hot runner system, which comprises a valve body, a valve needle, a runner, cylinders and a heating system, wherein the valve needle and the runner are arranged in the valve body; the system is characterized in that: the valve needle is arranged on a central line of the valve body; the valve body comprises a jet nozzle head, a jet nozzle body and a nozzle body which are sequentially and detachably connected with one another from top to bottom; the heating system is arranged at the periphery of the jet nozzle body; the jet nozzle body is provided with a cylinder shaft; and the cylinders are fixed at the two ends of the cylinder shaft. In the system, the central line of the valve needle is used as a symmetric axis for the two cylinders, so that the valve needle is uniformly and stably stressed during movement; meanwhile, the transfer of a large amount of heat is avoided, so that the hot runner system is stable in working performance and long in service life.
Description
Technical field
The utility model relates to TOP-TIP, relates in particular to the needle valve TOP-TIP.
Background technology
Hot flow path is the plastics maintenance molten condition that guarantees runner and cast gate by the way of heating, successfully is applied to process various plastic materials.
Single-point needle-valve TOP-TIP is a kind of as TOP-TIP, not only can improve the quality of products, economize in raw materials, and also can shorten the production cycle simultaneously, enhance productivity, and its processing is simple relatively, the price material benefit, greatly the client reduces cost.
Common single-point needle-valve TOP-TIP mainly comprises valve body, valve body outside cylinder system and heat-generating system.Wherein valve body mainly comprises the hot flow path main body, is positioned at chewing body and being positioned at the needle of hot flow path main body of hot flow path main body end, and heat-generating system mainly is in order to guarantee that melting glue guarantees its temperature by TOP-TIP the time.Single-point needle-valve TOP-TIP operation principle is exactly: move up and down by the needle in the middle of the hot mouth of air cylinder driven, be connected with the control signal of injection machine by magnetic valve, when injection moulding begins, needle shrinks back and allows heat chew gum outlet to open, allow melt enter die cavity, needle closes when injection moulding finishes, and closes glue-feeder, has finished injection molding operation one time.In hot flow path, must keep the melting state owing to melt glue, therefore overall thermal flow passage system temperature is higher, and there is the many places seal in cylinder system, seal frequent activities owing to cylinder piston in hot environment is subjected to heavy losses, so hot conditions greatly reduces the service life of single-point needle-valve system.In addition, because the traditional gentle cylinder of single-point needle-valve system valve body system, heat-generating system are all as one, cylinder power may cause stressed the occur non-equilibrium state of system at injection direction, is subjected to force unbalance even may draws a series of problems such as card needle, leakage glue.
The utility model content
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and the single-point needle valve TOP-TIP of a kind of simple in structure, long service life, stable work in work is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of single-point needle valve TOP-TIP, comprise valve body, place needle in the described valve body and runner, cylinder, heat-generating system, described needle places on the center line of described valve body, described valve body comprises that the purt that removably connects is in turn chewed head, purt is chewed body, chewed body from top to bottom, described heat-generating system places described purt to chew the periphery of body, described purt is chewed body and is established cylinder axis, and described cylinder is fixed on the two ends of described cylinder axis.
As optimize selecting, described purt is chewed head, purt and is chewed body, chews body and be spirally connected by a screw.
As prioritization scheme, described purt is chewed head, purt is chewed body, chewed body three's shaft centre line on same straight line.
As prioritization scheme, described heat-generating system comprises first heat-generating system and second heat-generating system, described first heat-generating system places described purt to chew the periphery that head is chewed the body touching position with described purt, and described second heat-generating system places described purt to chew body and described periphery of chewing the body touching position.
The cylinder core that described cylinder comprises cylinder body, moves in cylinder body, the inwall of described cylinder body is provided with sealing.
The beneficial effects of the utility model are: 1, two cylinders be fixed on the two ends that purt is chewed the cylinder axis of body, chew body with purt, heat-generating system separates, system is when work, though because the heat conduction meeting of cylinder axis uses temperature cylinder to raise a little, but because cylinder is independent and away from heat-generating system, the heat that heat conduction reaches cylinder seldom, on the other hand, the cylinder periphery also has enough spaces to design to guarantee the operation of cylinder system, thereby guarantees two cylinder inner seal liners not to be subjected to the hot environment effect and influence service life of seal; 2, even and symmetrical about the active force of two cylinders to needle 8, make that needle can balance and finish at a high speed and come and go the open and close action; 3, purt is chewed head, purt is chewed body, chewed status from design, can effectively reduce its difficulty of processing and mass production, and three's center is in same straight line, has increased the symmetry of system, thereby guarantees normally carrying out of needle action; 4, purt is chewed head, purt chews body, chew the body periphery can design heat-generating system easily, thus the temperature of can fine assurance melting glue by runner.
Description of drawings
Fig. 1 is the structural representation of a kind of single-point needle valve of the utility model TOP-TIP.
The specific embodiment
Below in conjunction with the drawings and specific embodiments a kind of single-point needle valve of the utility model TOP-TIP is described in further detail.
Please refer to Fig. 1, a kind of single-point needle valve of the utility model TOP-TIP comprises that the purt that is spirally connected in turn by screw 10 chews 5, purt is chewed body 6, chewed body 7.Runner 9 is chewed body 6 from purt and is crossing to and chews body 7.Purt 5 the center of chewing is the injection moulding center, and purt chews 5, purt is chewed body 6, chewed body 7 is benchmark with the injection moulding center all, three parts connect finish after its center overlap with needle 8, center and be in line, be the flow passage system center.
Purt is chewed body 6 and is established cylinder axis 1, and cylinder comprises that cylinder body 2, cylinder core 3,4, two cylinders of seal all pass purt and chew the cylinder axis 1 of body 6 and be fixed in two ends.
Chew 5 peripheries of chewing body 6 touching positions with purt at purt one heat-generating system (figure does not show) is set, chew body 6 at purt and add with the periphery of chewing body 7 touching positions another heat-generating system (figure does not show) is set.
The utility model in use, injection machine will melt glue to be chewed 5 from purt and begins to enter in the runner 9, enters mold cavity by runner 9, forms injection moulding.When gas when two cylinder lower cavity enter in the cylinder, cylinder axis 1 drives needle 8 and moves up, and opens heat and chew gum outlet and form into glue; When gas enters in the cylinder from two cylinder upper cavity simultaneously, just promoting cylinder core 3 simultaneously moves down, two cylinder balancings drive cylinder axis 1, needle 8 moves down rapidly under cylinder axis 1 effect, formation is to the sealing of gum outlet, also disconnected simultaneously glue forms the perfect outward appearance of injecting products, finishes whole injection operation.
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 technical scheme described above and design.
