Above-mentioned cam mechanism is as shown in figure 1, to the outer peripheral face radial direction of needle (50) in above-mentioned second piston (80)
The convex pin of 1 couple (55) of the side wall for being fixed on second piston (80) of protrusion, can house above-mentioned convex pin (55) front end and can be with
Make convex needle tray (53) formation that it is slided.Above-mentioned convex needle tray (53) is as shown in figure 3, by above-mentioned first piston (70) lower-upper length side
Can allowing above-mentioned needle (50) when being moved to linear reciprocation, linear reciprocation is displaced into the needle outer peripheral face of second piston (70) up and down
The straight-line groove (53a) that length direction is formed with above-mentioned second piston (50) can allow what above-mentioned needle (50) axle rotated when rising
Needle (50) outer peripheral face is formed and can housed thread groove (53b) shape that the front end of convex pin (55) is slided by certain anglec of rotation
Into.
Above-mentioned second piston (80) rises convex pin (55) when either declining and also rises or decline together, now possesses screw thread
The needle (50) that groove (53b) can house and allow the front end of convex pin (55) to slide can follow convex pin (55) rise and along thread groove
The hand of spiral rotation of (53b).Now because first piston (70) will not above-below direction movement, needle (50) also will not upper and lower
Only rotated to movement.
Hereinafter, the action for the cast gate valve needle device of said structure illustrates.
(I) it is molded the last stage (Fig. 1)
Fig. 1 is that first piston (70) is located at upper limit position, is connected to the lower end of needle (50) of first piston (70) in valve
It is located at upper limit position (H1) in pin hole (33), spray nozzle part is cut off in the bottom side of the wall of this upper limit position (H1) above-mentioned needle (50)
(30) molten resin path (31) outlet (31b) and cast gate (22) entrance (22a), the melting tree of molten resin path (31) is made
Fat can not be flow in die cavity (13).
(II) decline stage (Fig. 4) of needle
Fig. 4 is that needle (50) leads to from cut-out molten resin as first piston (70) drops to lower position under Fig. 1 states
The state that road (31) exports (31b) and cast gate (22) entrance (22a) moves along a straight line to lower position (H2) state.
Each corresponding molten resin leads to needle (50) connecting path (51) entrance (51a) with outlet (51b) in this case
It is not the position interconnected that road (31), which exports (31b) and is rotated in cast gate (22) entrance (22a) sustained height by certain angle axle,
Put.
(III) injection phase (Fig. 5)
The 4th chamber (82) on the downside of second piston (80) is supplied by the 4th stream (64) under the state of fig. 4 and compresses sky
Second piston (80) rises to upper limit position as shown in Figure 5 during gas.With second piston (80) rise convex pin (55) also together on
Rise, thread groove (53b) hand of spiral combined with the vertical motion needle (50) of convex pin along convex pin (55) rotates, such as Fig. 5
Shown, the entrance (51a) of connecting path (51) is each connected molten resin path (31) outlet (51b) with outlet (51b) with pouring
Mouthful (22) entrance (22a), thus molten resin path (31) the side molten resin of spray nozzle part (30) by cast gate (22) to die cavity
(13) surface incline direction is injected into die cavity (13).
Molten resin is injected into die cavity (13) by above-mentioned inclined cast gate (22) incline direction, therefore will not be noted
It is moulded into the phenomenon that type product surface forms the die cavity inner molten resin generation ripple of current mark (FLOW MARK) reason.And can
With the mobility in improved-type intracavitary portion.
(IV) cast gate is closed and gate part cuts off the stage (Fig. 6)
After above-mentioned injection phase is molded, second piston (80) drops to the lower decrease such as Fig. 4 states under Fig. 5 states
Put.Needle (50) is acted because of the cam mechanism of convex pin (55) and thread groove (53b) when second piston (80) declines, and rotation is to cutting
The off-position of disconnected molten resin path (31) and cast gate (22) and while close gate entry with molten resin lane exit
Cut off the resin of cast gate end protrusion.(as shown in Figure 4)
(V) opening of die cavity and the taking-up of shaped article
By above-mentioned (IV) stage, after the molten resin in die cavity is molded, state as shown in Figure 1
Needle (50) rise to movable platen (12) after upper limit position separated from fixed plate (11) and from die cavity (13) take out into
Type product.
In summary, the cast gate valve needle device of hot runner plastic injection mould of the invention, the melting entered from cast gate in die cavity
Resin tilts injection for the molten resin surface in die cavity, therefore the molten resin surface of filling is not in ripple inside die cavity
Line, its result can prevent shaped article surface flow marks (FLOW MARK）The bad generation of related injection molding, and this hair
Bright cast gate valve needle device, according to 2 sections of cam mechanism and dual piston actions, the side of needle while allowing the needle to be rotated
Face can be opened and closed inclined cast gate.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, it is included within the scope of the present invention.
