Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Present embodiments provide a kind of precision die structure of preceding mould pin prior to slipper block loose core, including take-up housing 2, sliding block
Mold insert 1, sliding block shovel 5, A plates 8, B plates 12, water gap plate 13, panel 7, preceding mold core 10, rear mold core 11, two side guides 6, inclined guide pillar 4
And pin.The slide block insert 1 is fixed on 2 right side of take-up housing, and the sliding block shovel 5 is set to the left side of take-up housing 2.Institute
The front and rear sides face for stating take-up housing 2 is respectively equipped with the hanging platform of protrusion, and each hanging platform is pushed down by side guide 6, and the side guide 6 is fixed
In on B plates 12, the take-up housing 2 is equipped with the inclined hole being adapted to inclined guide pillar 4, and 4 top of the inclined guide pillar is fixed on A plates 8, described
Sliding block shovel 5 is fixedly connected with A plates 8, and the water gap plate 13 is located above A plates 8, and the panel 7 is located above water gap plate 13；Institute
It states preceding mold core 10 to be located above rear mold core 11, the preceding mold core 10 and the shape that the cavity that rear mold core 11 is formed is product 9, product
9 right side is back-off structure, and the right side of the slide block insert 1 is located in the back-off of product 9, the slide block insert 1 equipped with it is preceding
The edge hole that mould pin 3 is adapted to, 3 top of the preceding mould pin are fixed on water gap plate 13, and the bottom of the pin passes through 9 He of product
Inlay hole.
Such as Fig. 1 and Fig. 2, in the present embodiment, slide block insert 1 is screwed in the right side of take-up housing 2, slide block insert
1 follows the movement of take-up housing 2 and moves.Sliding block shovel 5 is set to the left side of take-up housing 2, and lockking line position for backhoe is molding
It is unlikely to retreat under state.Sliding block shovel 5 is fixedly connected with A plates 8, is followed the movement of A plates 8 and is moved.Front and back the two of take-up housing 2
Side is respectively arranged with the hanging platform (not shown) of protrusion, and hanging platform is pushed down by side guide 6, and side guide 6 is fixed on B plates 12.That is,
The vertical shift of take-up housing 2 is limited, can only left and right horizontal movement.Take-up housing 2 is equipped with the inclined hole being adapted to inclined guide pillar 4, tiltedly
It is die opening state that guide post 4, which is inserted into inclined hole, and it is molding state that inclined guide pillar 4, which leaves inclined hole,.Such as Fig. 3, acted for mold line position
Die sinking and molding status diagram.Preceding mold core 10 is fixed on A plates 8 in the following, rear mold core 11 is fixed on above B plates 12, preceding mold core
10 with rear mold core 11 formed cavities be product 9 shape.Preceding mould pin 3 is adapted to edge hole, and 1 right side of slide block insert is located at product
In 9 back-off, the bottom of preceding mould pin 3 passes through product 9 and edge hole.
Further, such as Fig. 4, the right side of the sliding block shovel 5 is equipped on first tiltedly, and 401, lower inclined plane 403 and first
Vertical plane 402, first vertical plane 402 connect the first ramp 401 and the first lower inclined plane 403；2 left side of the take-up housing
Equipped under the second ramp 404, second being adapted to the first ramp 401, the first lower inclined plane 403 and the first vertical plane 402
Inclined-plane 406 and the second vertical plane 405.
Such as Fig. 1-Fig. 3, when die sinking, water gap plate 13 is first opened with panel 7, and the preceding mould pin 3 for being fixed on water gap plate 13 moves together
It is dynamic.When reaching certain distance, water gap plate 13 drives A plates 8 to move together, the inclined guide pillar 4 and sliding block shovel 5 being fixed on A plates 8
It moves together.First ramp 401 with and the first lower inclined plane 403 respectively with the second ramp 404 and the second lower inclined plane 406
Adaptation, for shoveling take-up housing 2.First vertical plane 402 is used to slide when the first vertical plane 402 of sliding block shovel 5 is detached from not yet
When the second vertical plane 405 of block 2, sliding block shovel 5 is to be close to take-up housing 2, so that take-up housing 2 will not be retreated toward left side.When
When first vertical plane 402 and the second vertical plane 405 completely disengage, inclined guide pillar 4 just touches the side wall of inclined hole, to drive cunning
Block 2 is retreated toward left side.At this point, preceding mould pin 3, which has been detached from slide block insert 1, reaches safe distance, i.e., before mould pin 3 bottom
Portion is pulled out from edge hole and product 9 to be come.Therefore, slide block insert 1 toward move left when, right side the core pulling from the back-off of product 9
Out, that is, mould pin 3 is prior to slipper block loose core before realizing.
Further, wear-resistant block 14 is equipped between the take-up housing 2 and B plates 12.Because take-up housing 2 is water with B plates 12
Prosposition moves friction, be easy to cause take-up housing 2 and abrasion condition occurs with 12 contact surface of B plates, causes displacement inaccurate, and mold damage.
Therefore wear-resistant block 14 is set between take-up housing 2 and B plates 12, the service life of entire mold can be extended and promotes service precision.
Using above-mentioned each technical solution, the utility model is inserted by the way that pin is arranged above slide block insert with pin
To edge hole, hole is inlayed by first exiting pin, then inclined guide pillar is exited into inclined hole, product is formed from preceding mold core and rear mold core
Core pulling comes out in cavity, simple in structure, is easy production, and production efficiency is high.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement etc., should be included in the guarantor of the utility model made by within novel spirit and principle
Within the scope of shield.
