Description
Technical field
The utility model relates to technical field of mold, specifically, being related to a kind of pin core-pulling mechanism.
Background technique
In injection mould group, the demoulding of tubular products is needed first to extract the pin in tubular products out, it then again will pipe
The sliding block of shape end is removed, to realize the demoulding of product.
Referring to FIG. 1, the slide block B 12 for withstanding product is placed on mold base 11, sliding block A14 is set in slide block B 12, passes through cunning
The side of block B12 carries out molding limit to the end face of product 13, and sliding block 14 is fixed with for the molding pin 141 of product 13, mould
It is further fixed on fixing seat 17 on embryo 11, passes through bolt draw bar 16 in fixing seat 17, bullet is equipped between bolt draw bar 16 and fixing seat
Spring 18,16 other end of bolt draw bar are fixed with sliding block A14.The oblique of auxiliary guiding is additionally provided between sliding block A14, slide block B 12
Guide post 15.Bolt draw bar 16 holds out against sliding block A14 in slide block B 12 when molding, and lock pin is made to stretch out slide block B 12, and spring 18 is in pressure
Contracting state.When die sinking, the power of puller bolt pull rod 16 is shed, and spring 18 resets, and band movable slider A14 is mobile, due to sliding block A14 with
Complete frictionally between slide block B 12, slide block B 12 and sliding block 11, when sliding block A14 and the frictional force of slide block B 12 are greater than or equal to
When slide block B 12 and the frictional force of sliding block 11, causes sliding block A14 to move together with slide block B 12, lose slide block B 12 to product end
The barrier effect in portion, also completely cooling product is not easy to the case where causing deformation to be even broken.Influence the molding matter of product
Amount.
Utility model content
The purpose of this utility model is to provide a kind of pin core-pulling mechanisms, effectively avoid deformation when product stripping, protect
Demonstrate,prove the Forming Quality of product.
Technical solution used by pin core-pulling mechanism disclosed by the utility model is:
A kind of pin core-pulling mechanism, including mold base, the slide block B above mold base and the sliding block A in slide block B, institute
It states sliding block A and is connected with pin, the pin stretches out the side of slide block B, is additionally provided with fixing seat, the fixing seat above the mold base
Interior to be equipped with bolt draw bar, described bolt draw bar one end connect with sliding block A, sets between the bolt head and fixing seat of the bolt draw bar
There is spring, inclined guide pillar is equipped between the sliding block A and slide block B, the fixing seat is fixed on slide block B.
Preferably, baffle is equipped at the head of screw of the bolt draw bar, the baffle is for blocking spring one end.
Preferably, the fixing seat is fixed by bolts in slide block B.
Preferably, interior limit hole is equipped in the fixing seat, the spring one end is held out against in interior limit hole.
The beneficial effect of pin core-pulling mechanism disclosed by the utility model is: when molding, bolt draw bar by sliding block A hold out against in
Slide block B, pin stretch out slide block B, and product forms on pin, and spring is compressed in closing membrane process.After die sinking, inclined guide pillar is outside
It pulls out, plays the role of auxiliary slider A retrogressing, while the pressing force of bolt draw bar is removed, spring reset, bolt draw bar is in bullet
It is moved under the action of spring, thus it is mobile with movable slider A, since fixing seat is fixed in slide block B, so process of the spring in rebound
In, give one breaking-out of slide block B to exert oneself, slide block B is not mobile with sliding block A.To realize that sliding block A drives pin first to exit product,
Finally slide block B is detached from product under the action of mold base, takes off product completely, ensure that the Forming Quality of product.
Detailed description of the invention
Fig. 1 is the cross-sectional view of pin core-pulling mechanism in the prior art；
Fig. 2 is the cross-sectional view of the utility model pin core-pulling mechanism.
Specific embodiment
The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below:
Referring to FIG. 2, a kind of pin core-pulling mechanism, slide block B 22 including mold base 21, above mold base 21 and being set to is slided
Sliding block A24, the sliding block A24 in block B22 are connected with pin 241, and pin 241 stretches out the side of slide block B 22,21 top of mold base
It is additionally provided with fixing seat 27, is equipped with bolt draw bar 26 in fixing seat 27,26 one end of bolt draw bar is connect with sliding block A24, bolt draw bar
It is equipped with spring 28 between 26 bolt head and fixing seat 27, inclined guide pillar 25, inclined guide pillar 25 are equipped between sliding block A24 and slide block B 22
Play the role of auxiliary mould-opening, fixing seat 27 is fixed on slide block B 22, and preferably fixing seat 27 is fixed by bolts in slide block B 22.
Baffle 29 is equipped at the head of screw of bolt draw bar 26, baffle 29 is for blocking 28 one end of spring.It is set in fixing seat 27
There is interior limit hole, 28 one end of spring is held out against in interior limit hole, and spring 28 is sheathed on bolt draw bar 26.Pass through baffle 29 and limit
Hole limits spring 28, makes 28 fixation of spring.
In above scheme, when molding, bolt draw bar 26 holds out against sliding block A24 in slide block B 22, and pin 241 stretches out sliding block
B22, product form on pin 241, and spring 28 is compressed in closing membrane process.After die sinking, inclined guide pillar 25 is pulled out, and is played
The effect that auxiliary slider A24 is retreated, while the pressing force of bolt draw bar 26 is removed, spring 28 resets, and bolt draw bar 26 is in bullet
It is moved under the action of spring 28, thus it is mobile with movable slider A24, since fixing seat 27 is fixed in slide block B 22, so spring 28 exists
During rebound, 22 1 breaking-outs of slide block B is given to exert oneself, slide block B 22 is not mobile with sliding block A24.To realize sliding block A24 band
Dynamic pin 241 first exits product, and finally slide block B 22 is detached from product under the action of mold base, takes off product completely, ensure that production
The Forming Quality of product.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
