Detailed description of the invention
To the technical scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 7:
Figure 2 shows that, hot-runner injection mold device of the present utility model is to utilize piston to allow needle move, and recycling needle comes the mode of opening and closing mould gate, the relevant content of hot-runner injection mold device of so-called " valve " mode.But the utility model is not limited to described needle valve cast gate mode, can also be applied in open cast gate mode.
Hot-runner injection mold device of the present utility model as shown in Figure 2, possesses fixed upper die (11) (hereinafter to be referred as " cover half "), form the movable type lower mould (12) (hereinafter to be referred as " dynamic model ") of die cavity (13) together with cover half (11), described die cavity (13) has the inclined-plane (14) that opens and closes the inclination of direction formation certain angle with respect to dynamic model (12), and this inclined-plane (14) possess cast gate (15).Cast gate (15) in the utility model forms certain angle with mould die sinking direction.
Described cover half (11) upside being provided with possesses the flow distribution plate (20) of the hot flow path (22) that can guide molten resin.Described flow distribution plate (20) is the dull and stereotyped piece that bottom surface (23) forms with plane parallel above cover half (11).The flow distribution plate (20) that the utility model uses also need not be considered the problem such as special structure or shape change.
Hot-runner injection mold device of the present utility model, nozzle is imbedded at a slant and is arranged at cover half.This nozzle makes can be injected in the die cavity (13) of mould by described cast gate (15) by the high-temperature fusion resin of described flow distribution plate (20) side hot flow path (22).
Described nozzle (30) as shown in Figure 2, by tilt to insert towards cast gate (15) nozzle body (32) that is arranged at cover half (11) with, the nozzle head (36) can the horizontal direction (diametric(al)) along the upper surface of described nozzle body (32) (33) to nozzle body sliding forms.
Described nozzle body (32) inserts and is arranged at cover half (11) towards cast gate (15) inclination, and upper surface (33) are with respect to bottom surface (23) tilted configuration of described flow distribution plate (20).Possess resin passage (31) along the central shaft length direction of nozzle body (32), the top of described resin passage (31) is from the center deviation of nozzle body (32) to prolongation.
The structure of the upper end of nozzle body (32) and nozzle head (36) combination as shown in Figure 3.There is the guide rail (37) extending along the diametric(al) of nozzle body (32) upper surface (33) of described nozzle body (32), and there is the guide-track groove (39) with described guide rail (37) combination the bottom surface of described nozzle head (36).Described nozzle head (36) can slide in conjunction with guide-track groove (39) and guide rail (37).
One side, upper end of nozzle head (36) possesses the contact-making surface (34) of being close to bottom surface (23) the face way of contact of described flow distribution plate (20), forms the connecting path (35) that the hot flow path (22) of bottom surface (23) direction opening of flow distribution plate (20) and the upper end open of the resin passage (31) of nozzle body (32) interconnect on the position that the bottom surface (23) of this contact-making surface (34) and flow distribution plate (20) is close to.
This nozzle head (36) is as shown in Fig. 4 to Fig. 6 stage, because tight lock part material (40) slides to flow distribution plate (20) direction.Nozzle head (36) forms and is positioned at sideways the 1st downward-sloping locking face (36a) of contact-making surface (34) negative side.Described tight lock part material (40) possesses the 2nd locking face (41) being in contact with one another with described the 1st locking face (36a).Therefore, as shown in Figures 4 to 6, tight lock part material (40) is tightened when it is declined to piston bush (61) direction with the mobile screw of locking (44), the 2nd locking face (41) of tight lock part material (40) can pressurize to side, the 1st locking face (36a) of nozzle head (36) can be because the pressure being subject to slides in the other direction to tight lock part material (40), until the contact-making surface (34) of nozzle head (36) is close to the bottom surface (23) of flow distribution plate (20).As shown in Figure 6, tight lock part material (40) can be close to the bottom surface (23) of flow distribution plate (20) and be fixed to nozzle head (36) because of the contact-making surface (34) of nozzle head (36).
On the other hand, as shown in Figure 7, be close under the stationary state of flow distribution plate (20) bottom surface (23) at the contact-making surface (34) of nozzle head (36), needle (38) inserts and is set in the resin passage (31) of nozzle body (32) from the upside of nozzle head (36).
Described needle (38) can be followed and be imbedded the piston action of the piston portion material (60) being arranged in cover half (11) and above-below direction moves up and down.As shown in Fig. 3 and Fig. 7, described needle (38) inserts the upper end (38a) arranging with the rear needle of nozzle body (32) can expose the outside in nozzle head (36).Described piston portion material (60) is by forming with lower component: coaxial and imbed the piston bush (61) that is arranged on cover half (11) with nozzle body (32); Be arranged on described piston bush (61) inner space and according to the piston (62) of oil pressure or air pressure action; In order to link with piston (62), extend to dynamic model (11) outside and the 1 pair of piston rod (63) with needle (38) upper end (38a) combination from described piston (62).
Described piston (62) is because of the oil pressure or the pneumatics knee-action that are subject to outside and provide and drive 1 pair of piston rod (63) to move up and down, make this piston rod (63) above do oscilaltion action with the needle fixed bar (64) of fixed screw (65) combination, the needle upper end (38a) being fixed on this needle fixed bar (64) drives needle (38) to do lifting action simultaneously.
So, the piston portion material (60) that makes needle (38) action is at the downside of flow distribution plate (20) and imbed and be arranged on cover half (11), need to change needle (38) time, need to not split flow distribution plate (20) or piston portion material (60) and only needle (38) need be split out to replacing from nozzle (30) from mould.
And, even if flow distribution plate (20) is because of the backward length direction thermal expansion of high-temperature heating, because the contact-making surface (34) of nozzle head (36) is surface contact state and can slides, so it is upper the power of thermal deformation can not to be communicated to nozzle (30), therefore can prevent needle (38) distortion.
The oblique cast gate of the utility model with the beneficial effect of hot-runner injection mold device is:
One, the general plate flow distribution plate that use and die horizontal arrange, saves the flow distribution plate manufacturing cost of special construction shape and the manufacturing cost of mold integral;
Two, be designed with and prevent that flow distribution plate thermal deformation from causing the structure of the nozzle assembly of needle distortion, improves the life-span;
Three, the assembling of nozzle assembly and decomposition are simple, and nozzle assembly or as simple and easy in the part replacement of the nozzle assemblies such as needle is provided;
Four, compared to existing technology, the utlity model has the advantages such as reliability is high, registration, compact conformation, nozzle assembling is easy to maintenance, cooperation is tight, does not leak glue, and needle-valve is convenient for installation and maintenance, have market prospects widely at Die & Mould Market simultaneously.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
