Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As depicted in figs. 1 and 2, a kind of accessible internal core-pulling mechanism, including the guide plate 2 being fixedly connected with lower die 1, institute
Drag hook 3 is slidably connected in the guide plate 2 stated, the drag hook 3 is fixedly connected with upper mold 4, is set between upper mold 4 and lower die 1
There is middle mould 5, is equipped with a voussoir 6 being flexibly connected with middle mould 5 in the middle mould 5, the guide plate 2 is close to the one of middle mould
Side is equipped with the first inclined-plane 7, and the voussoir 6 is equipped with the second inclined-plane 8 close to the side of guide plate 2, and spring 9 is equipped in voussoir 6,
9 both ends of spring bear against voussoir 6 and middle mould 5, and core pulling slide 10, the core pulling slide are installed in lower die 1
Core pulling column 11 is slidably connected in 10, is extended in upper mold 4 at the top of core pulling column 11.
It will be appreciated by those skilled in the art that the second inclined-plane 8 matches with the first inclined-plane 7, when drag hook 3 pulls voussoir 6 simultaneously
When mould 5 and upper mold 1 rise in drive, the second inclined-plane 8 contacts the first inclined-plane 7, thus in making 6 compressed spring 9 of voussoir and being retracted into
In mould 5, drag hook is separated with voussoir 6, and upper mold 4 continues to be opened, and the separation with middle mould 5 can be completed.
Core pulling column 11 remains stationary in the axial direction in middle mould and upper mold uphill process, when core pulling column 11 is in radial force
When, core pulling column 11 is slided along core pulling slide 10, and product is made to be detached from core pulling column 11, therefore, whole in the core pulling action of die sinking process
A core pulling process will not generate obstacle, so that torque product be enable smoothly to demould.
Specifically, guide plate 2 is equipped with the drag hook accommodating cavity 12 to match with drag hook 3, and drag hook 3 is inserted into drag hook accommodating
In chamber 12 and 3 bottom of drag hook is extended outside drag hook accommodating cavity 12, and 3 bottom of drag hook is the position that clamping is cooperatively formed with voussoir 6,
Preferred embodiment, 3 bottom of drag hook are equipped with a guiding surface 17, in molding, when guiding surface 17 encounters the second inclined-plane 8, lead
It is entered in middle mould to inclined-plane compressing voussoir 6, so that drag hook bottom be made to cross voussoir, drag hook can be formed with voussoir and is clamped.
The guide plate 2 is equipped with voussoir sliding groove 13,7 connecting wedge sliding groove of the first inclined-plane close to the side of middle mould 5
13 tops, when the second inclined-plane 8 of voussoir 6 slides at the first inclined-plane 7 along voussoir sliding groove 13, the second inclined-plane 8 is oblique along first
Face sliding, enters voussoir in middle mould, to be that drag hook and inclined-plane are detached from.
In the present embodiment, spring 9 is in compressive state, elastic force of the voussoir 6 in spring 9
Voussoir 6 is equipped with limiting slot 14, is equipped with gag lever post 15,15 bottom of gag lever post and lower die 1 in limiting slot 14
It is fixedly connected.Limiting slot 14 is elongated.The distance that voussoir 6 can the move horizontally i.e. length of limiting slot 14, this length can root
It is designed at a distance from needing to be detached between drag hook according to voussoir.
Core pulling slide 10 is equipped with I-shaped slot 16, and 11 bottom of core pulling column snaps onto I-shaped slot 16 thus with core pulling slide
10 are slidably connected.
The course of work of the utility model is:
In molding, upper mold 4 is close to middle mould 5, and upper mold 4 drives drag hook 3 to slide along drag hook accommodating cavity 12, when guiding surface 17
When contacting the second inclined-plane 8, drag hook 3 is oppressed voussoir 6 and is retracted into middle mould along level sliding, so that drag hook bottom is made to cross voussoir 6,
After drag hook crosses voussoir 6, voussoir 6 pops up under the elastic force effect of spring 9, and drag hook and voussoir are formed and be clamped, and forms molding.
In die sinking, upper mold 4 pulls drag hook 3 to move upwards, and drag hook 3 pulls voussoir 6, the same luck of mould 5 in the drive of voussoir 6
Dynamic, upper mold and middle mould are progressively disengaged with core pulling column 11, and core pulling column 11 is radially slided when contacting with product along I-shaped slot 16, with
Product is separated in radial and axial upper formation core pulling, and behind the second inclined-plane 8 of voussoir 6 and the contact of the first inclined-plane 7, voussoir 6 is gradually
It is retracted into mould, so that drag hook and voussoir be made to be detached from, completes the separation of upper mold and middle mould, the mandril in lower die can be used later
Product is ejected.
When due to die sinking, middle mould and product are moved at the same time, therefore actually middle mould is integrally formed upward top to product and lifts
Power, contact area is big, and product does not easily cause damage, to be able to achieve normal die sinking.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application.
Although herein more using lower die 1, guide plate 2, drag hook 3, upper mold 4, middle mould 5, voussoir 6, the first inclined-plane 7, the
Two inclined-planes 8, spring 9, core pulling slide 10, core pulling column 11, drag hook accommodating cavity 12, voussoir sliding groove 13, limiting slot 14, gag lever post
15, the terms such as I-shaped slot 16, guiding surface 17, but it does not exclude the possibility of using other terms.Only using these terms
The essence in order to be more convenient to describe and explain the utility model, be construed as any additional limitation all and be with
What the spirit of the present invention was disagreed.
