The present invention relates to be used for the detent mechanism of pressing mold, relate in particular to a kind of detent mechanism that is placed in the pressing mold, the formation of pressing mold makes material is enclosed in the die cavity of determining between cover half side plate (hereinafter referred to as " solid plate ") and the dynamic model side plate (hereinafter referred to as " moving platen "), forming goods, the effect of this mechanism is that fixed, moving platen is positioned.
Now, with reference to accompanying drawing 13 pressing mold that is provided with traditional detent mechanism in it is introduced.General conventional die with label 1 sign comprises and is installed in the cover half installing plate 2 on the not shown press cover half frame and is installed in dynamic model installing plate 3 on the press dynamic model frame.
One solid plate that is used as former 4 mounted thereto is arranged on the cover half installing plate 2.Also be equipped with on the installing plate 2 make molten resin material from press cylinder barrel nozzle be injected into pressing mold 1, passage or stimulate the menstrual flow the effect sprue bush 10.The resin that is injected into pressing mold 1 through sprue bush 10 enters the cross gate that is formed on solid plate 4 sides then, enters die cavity through cast gate then.
Dynamic model installing plate 3 has moving platen 5, and moving platen 5 roles are as by dash receiver 6 and backing plate 7 former mounted thereto.
Pressing mold 1 is by fixed, moving platen 4,5 separated into two parts.Specifically, along with the motion of press frame, moving platen 5 relative solid plates 4 move on the direction vertical with template, thereby decide, the die sinking of moving platen and matched moulds operation.Fixed, moving platen 4,5 toward each other close up, therefore limit and the corresponding die cavity A of goods that treats die forming.
That pressing mold 1 is placed in addition is fixed, between the moving platen 4,5, be used to make fixed, moving platen 4,5 each all be positioned at detent mechanism on the correct position.As shown in the Figure 15 that amplifies, detent mechanism comprises the sleeve 11 that is placed on the solid plate 4 and is configured in pin member 12 on the moving platen 5.During matched moulds, pin member 12 is inserted sleeves 11, thereby fixed, moving platen 4,5 all is positioned on the tram.
Figure 14 shows the pressing mold that another kind of traditional detent mechanism is arranged in it.The structure of this pressing mold self is substantially with shown in Figure 13 identical, its detent mechanism is illustrated in and amplifies among Figure 16, comprise by packing ring 13 being installed in female part on the solid plate 4, and be installed in male part 16 on the moving platen 5 by packing ring 15, male part 16 has a taper protruded stigma 16a.

1-12 is introduced detent mechanism of the present invention with reference to the accompanying drawings.
The sort of pressing mold of introducing in conjunction with prior art above detent mechanism of the present invention is applied to.Therefore, detent mechanism of the present invention is suitable for fixed, moving platen location in the pressing mold, and the formation of pressing mold makes material is enclosed in the die cavity of determining between fixed, the moving platen, and forms goods therefrom.
At first, introduce an embodiment of detent mechanism of the present invention with reference to Fig. 1 and 2.To install with the solid plate 4 of sleeve 21 with screw 20.To install with the moving platen 5 of pin member 12 by screw 22 as fixture.
Disposed the ball distance ring 23 of guide member effect in the sleeve 21.That ball distance ring 23 comprises is one cylindric, pedestal 24 and a plurality of bearing 25 of its both ends open, and each bearing 25 all is placed on the perisporium of pedestal 24 rotationally, plays the effect of sliding part.The external diameter of ball distance ring 23 is consistent with the internal diameter of sleeve 21 substantially, but its axial length is than the weak point of sleeve 21.The internal diameter of ball distance ring 23 is bigger than the head of screw 20, prevents that therefrom it from contacting with screw 20.When this scheme can contact ball distance ring 23 with the inner surface of sleeve 21, also can make retainer motion vertically in sleeve 21 in a preset range.
Be clamped in the sleeve 21 in order to ensure ball distance ring 23, at inlet or holder 26 of the place's of entering configuration of sleeve 21.Like this, holder 26 plays the backstop effect, and it prevents that retainer 23 from leaving sleeve 21.Therefore, holder 26 can be made for example an open loop or analog.
The elastic component that has been mounted with the thrust unit effect between sleeve 21 bottoms and ball distance ring 23 is a spring 27.The internal diameter of spring 27 is greater than the head of screw 20, so the head of screw 20 can be contained in the spring 27.
Also dispose one on the bottom of sleeve 21 with screw 20 fastening plain washers 28 thereon, plain washer 28 plays receiving element.The external diameter of plain washer 28 causes plain washer 28 is contained in the spring 27 less than the internal diameter of spring 27.In addition, therefore the external diameter of plain washer 28 makes ball distance ring 23 can contact with plain washer 28 when arriving the deepest part of sleeve 21 greater than the internal diameter of the pedestal 24 of ball distance ring 23.In addition, the thickness of plain washer 28 make allow sleeve 21 the height of deepest part when plain washer 28 contacts with ball distance ring 23, be enough to make the spring 27 of contraction to be contained in this deepest part.
Therefore, even forced down by pin member 12 reinforcings when aforesaid ball distance ring 23, when the deepest part of arrival sleeve 21 contacted with contraction spring simultaneously, ball distance ring 23 contacted and is blocked with plain washer 28 because of it.So just prevent spring 27 crampings between the bottom of ball distance ring 23 and sleeve 12 effectively, damage from preventing spring 27.
In the embodiment that is introduced, plain washer 28 is connected in the detent mechanism.As a kind of replacement, also size can be suitable for protect in a similar manner a projection of spring 27, integral body is arranged on the deepest part of sleeve 21.
The effect of spring 27 is to promote ball distance ring 23 towards holder 26.When not applying resistance on ball distance ring 23, retainer 23 moves under spring 27 thrust, and it is clamped on the holder 26.
The detent mechanism of the embodiment that is introduced among Fig. 3, expression sleeve 21 is installed in the situation on solid plate 4 and the cover half installing plate.Fig. 4 shows that then this detent mechanism middle sleeve 21 is installed in the situation on moving platen 5 and the dash receiver.
In addition, the pin member that is connected in the foregoing description detent mechanism can the mode shown in Fig. 5-7 constitute, and these figure have showed A type pilot pin 12a, Type B pilot pin 12b and the C type pilot pin 12c that determines according to JISB 5107 respectively.
8-10 is introduced the operational circumstances of embodiment detent mechanism during matched moulds with said structure with reference to the accompanying drawings.
Fig. 8 shows the pressing mold that is in die opening state.Ball distance ring 23 is promoted down by spring 27, retainer is remained on place on the holder 26 of sleeve 21 porch.
When the beginning matched moulds, pin member 12 begins to insert sleeve 21 with its end.Present embodiment prevents pin member 12 because a matched moulds just inserts in the ball distance ring 23 immediately.Because the pressing mold motion, the end of pin member 12 compresses spring 27 forcibly, during endways in abutting connection with ball distance ring 23 inlets retainer 23 is pressed into sleeve 21, prevents that thus pin member 12 is inserted into ball distance ring 23.
Described embodiment detent mechanism constitutes like this: i.e. when the ball distance ring 23 in pin member 12 maintenance insertion sleeves 21, or ball distance ring 23 assigns between sleeve 21 and the pin member 12, on the bearing 25 of ball distance ring 23 load that adds is in advance just arranged.Thereby in this state, the bearing 25 of retainer 23 is clamped between the inner surface of the outer surface of pin member 12 and sleeve 21.For this reason, the overall diameter of bearing 25 is done slightly greater than the gap between pin member 12 outer surfaces and sleeve 21 inner surfaces.This predetermined difference in size is called " preload ".In described embodiment, preload is limited between 10 μ m to the 20 μ m.This scheme causes large diameter bearing 25 to clamp in the more closely-spaced gap, has applied preload and make on the bearing 25.This just allows bearing 25 to keep rolling when contacting with the inner surface of sleeve 21 is constant with the outer surface of pin member 12 at it.The axis that causes pin member 12 is with the axis alignment of sleeve 21 or overlap, and occurs the gap thus between the two.
When continuing matched moulds, pin member 12 begins to insert ball distance ring 23, maintains aforesaid preload in pin member 12 and 21 in sleeve simultaneously, causes fixed, moving platen to be located each other.
When continuing matched moulds again because matched moulds pin member 12 advance the pucks thereby make pin member 12 and sleeve as shown in Figure 10, by ball distance ring 23 will decide, moving platen 4,5 accurately locatees.
As mentioned above, ball distance ring 23 has the preload that is set between 10 μ m and the 20 μ m, and making the gap between guiding pin member 12 and the sleeve 21 thus is zero, different with the sleeve combination with pin member in the prior art.
Then, when the beginning die sinking, the slip of pin member 12 and ball distance ring 23 and the elastic force of spring 27 remain on the holder 26 bearing 25 of retainer 23 when rotating a little.When pin member 12 was deviate from from ball distance ring 23 fully, because the elastic force effect of spring 27, the ball distance ring 23 of having eliminated preload rotated in sleeve 21 as an integral body, caused ball distance ring 23 to change along the position of its circumferencial direction.Therefore, when matched moulds next time, ball distance ring 23 is different in abutting connection with the state of pin member 12 with the last time, thereby prevents that retainer from producing uneven wear.
Figure 11 shows the conventional resins pressing mold shown in Figure 14, and wherein the detent mechanism of the embodiment of the invention in the pressing mold has substituted taper yin, yang spare 16,14.Figure 12 shows the conventional resins pressing mold shown in Figure 13, and in this pressing mold, the detent mechanism of described embodiment and traditional pin member 12 and sleeve 21 combine.
The binding resin pressing mold is introduced above.But in the enforcement afterwards, detent mechanism of the present invention can be used for connecting in other various moulds that are different from resin moulding-die, for example can be used in the ingot casting mould or similar mould that carries out the low-melting-point metal compression molding.
In described embodiment, guide member is made up of the ball distance ring 23 that comprises bearing 25.As a kind of replacement, a kind of roller retainer also can be used for the present invention.The roller retainer comprises pedestal and a plurality of rotatable roller element that is placed on the base peripheral wall, plays the sliding part effect of its both ends open.
Can find out that from above-mentioned introduction the present invention has following advantage.
More particularly, in comprising traditional detent mechanism of taper yin, yang spare, adjacency state or degree are to determine with sensation and/or experience between yin, yang spare cone-shaped surface, require the proficiency skills of height thus.The present invention has eliminated this shortcoming effectively.
In addition, the present invention has also eliminated in the prior art to guaranteeing that adjacency between the taper yin, yang spare requires the Height Adjustment operation of carrying out.
In addition, in the prior art, the cone angle of yin, yang spare is reduced, and causes yin, yang spare is adjusted, and considers between yin, yang spare that producing card stings the taper that makes yin, yang spare and partly have slightly and improve, and this can cause the position error between yin, yang spare.On the contrary, formation of the present invention makes can apply preload to pin member and guide pin bushing, prevents this position error therefrom effectively.
Use ball distance ring as guide member among the present invention, guaranteed that the ball of ball distance ring contacts with sleeve point with pin member, compare with the conventional lead mechanism that just constitutes thus, reduced scraping between pin member and the sleeve by pin member and sleeve.
In addition, traditional guide mechanism is the contact of employing face between pin member and sleeve, and this can cause resistance to sliding to increase.On the contrary, what the present invention produced owing to the point between ball distance ring, pin member and sleeve contacts is resistance to rolling, guarantees to have improved sliding capability.
And the present invention also manifested a kind of satisfactory performance, can effectively utilize the narrow space in the pressing mold thus.
Though introduced the preferred embodiment of the present invention with reference to accompanying drawing, can make various remodeling and variation under Xu Shu the enlightenment in the above.It is therefore to be understood that within the scope of the appended claims and can implement the present invention in the mode that is different from concrete introduction.
