Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.
As shown in Figure 1, 2, the detachable connection ramp-roof structure of a kind of injection mold disclosed in the utility model, be divided into above and below
Two parts, top is tiltedly sliding guiding, ejects spacing, support stress, shaped portion, and bottom is thimble structure part.Specifically,
Including oblique top 2, insert 3, dynamic model backing plate 4 and thimble 5, be provided with vertical thimble pilot hole in dynamic model backing plate 4, thimble 5 with
Thimble pilot hole is slidably matched；Insert 3, which is located in the top of dynamic model backing plate 4, insert 3, oblique top chute 10, and oblique top is slided
Groove 10 is outward-dipping from bottom to top, and oblique top 2 is slidably matched with oblique top chute 10；The upper end of thimble 5 is provided with T-type structure vertically
9, there is the T-shaped chute 8 being adapted to T-type structure 9 lower end of oblique top 2, and T-type structure 9 is mounted in T-shaped chute 8.T-type structure 9 and thimble 5
It is integrally manufactured.Provided with cavity 13 at the top of dynamic model backing plate 4, the bottom of thimble pilot hole Through-cavity 13, the upper end of thimble 5 puts in cavity 13
In.
The detachable connection ramp-roof structure of injection mold also includes thimble backing plate 7, and lower end and the thimble backing plate 7 of thimble 5 connect
Connect.Further, thimble 5 is connected by thimble fixed plate 6 with thimble backing plate 7, and thimble fixed plate 6 is located at the top of thimble backing plate 7.
Button bit shaped portion is completed by oblique top 2, and oblique top 2 is fastened with product 1, and oblique top 2 can also in the outside of product 1
In the inner side of product 1.Oblique top 2 is the vertical part structure for having the word groove 12 of 7 word groove 12,7 being adapted to thimble 5 in 7 fonts, insert 3
Into oblique top chute 10.After matched moulds, oblique top 2 is just contained in 7 word grooves 12, now the top surface of oblique top 2 and the top of insert 3
Face is flushed.
The top of oblique top 2 can be breaking face 11 or interiors of products glue position, and the head of oblique top 2 can do a breasting
Face, as benchmark during processing, short transverse size is easily guaranteed that precisely, drives thimble 5 to pull oblique top by thimble backing plate 7 during reset
2 returns.The top of thimble 5 is connected and relative motion with the bottom of oblique top 2 by T-shaped chute 8, it is desirable to T-type structure 9 and T-shaped cunning
Groove 8 is slidably matched, according to the shift position of oblique top 2, and the center of thimble 5 can be consistent with the center of oblique top 2, or in thimble 5
Heart deviation oblique top 2 moving direction side, specific shift value can flexibly be set according to actual conditions.
Usually using common thimble processing top into T-type structure 9, the bottom surface of oblique top 2 is also machined to T-shape structure.With it is general
Logical thimble structure is essentially identical, unlike, the thimble on moving platen or dynamic model backing plate 4, which is oriented to interporal lacuna, will do small, double
While there is 0.03~0.05mm gap, common die is generally 0.5mm or so.
It is slightly different when die-filling with traditional dies assemble method, oblique top 2 is initially charged with insert 3, thimble 5 passes through thimble
Backing plate 7, dynamic model backing plate 4, first load the T-type structure 9 at the top of thimble 5 in the T-shaped chute 8 of the lower end of oblique top 2, then thimble 5 revolves
Turn 90 °, as shown in Figure 3,4, make T-type structure 9 and T-shaped chute 8 formation fastening form, at this moment fixed thimble 5 is spacing in thimble
On plate 6, oblique top 2 just links together with thimble 5, constitutes Slanted ejecting component., as shown in Figure 5,6, only need to be by thimble 5 during form removal
T-type structure 9 be rotated by 90 ° in T-shaped chute 8 after can smoothly dismantle.
During matched moulds, oblique top 2 is retracted the position for ensureing short transverse by thimble backing plate 7, and during die sinking, injection machine top rod is with top
Pincushion plate 7 does ejection motion, and now, oblique top 2 produces the motion of both direction in the presence of oblique top chute 10：One is ejection
The ejection campaign in direction, another be with ejection direction back-off stripping movement in 90 ° so that realize the smooth demoulding of product 1,
Ejection, reaches the purpose smoothly produced.
Ramp-roof structure of the present utility model be divided into above and below two parts, oblique top 2, support force part oblique top 2 " 7 " word
At type step, shaped portion is the top of oblique top 2, and bottom is the structure division of thimble 5.Specifically, as shown in Fig. 2 when ejecting, pushing up
Rod is withstood on thimble backing plate 7, promotes thimble 5 to drive oblique top 2 to be moved obliquely along the oblique top chute 10 in insert 3, real
The existing function of abjection buckle and ejecting product 1, meanwhile, the also occurred level direction in the presence of the T-shaped structure of chute 8 of oblique top 2
Displacement.During matched moulds, by ejector retainner plate resetting means, drive oblique top 2 oblique along the oblique top chute 10 in insert 3 by thimble 5
Move down, meanwhile, with the structure division of T-type structure 9 relative position movement also occurs for T-shaped chute 8, returns to initial injection state,
Into next circulation.
The utility model reduces mould processing cost, it is to avoid deformed caused by oblique top is long, oblique top passes through T-shaped with thimble
Chute is connected, and assembling is simple, can effectively reduce processing cost, and T-shaped chute can realize mass motion and the inside of upper and lower part
Relative motion；Position is limited small, and flexibility is strong, it is to avoid when having other structures because of fixed plate, thimble backing plate, the interference easily caused
Phenomenon, the utility model is simple and practical, economic and reliable, can be widely applied.
Certainly, the utility model can also have other numerous embodiments, without departing substantially from the utility model spirit and its essence
In the case of, those skilled in the art can make various corresponding changes and deformation, but these according to the utility model
Corresponding change and deformation should all belong to the scope of the claims appended by the utility model.
