Technical field
The present invention relates to a kind of molds, and in particular to a kind of core mold with material returned function belongs to technical field of mold.
Background technique
Sand core generallys use core mold manufacture, and the core mold for manufacturing sand core includes upper mold and lower die, upper mold with
Structure forming cavity after lower die molding, first to the intracavitary injection precoated sand of type when manufacturing sand core, precoated sand solidifies shape in a heated condition
It at sand core base, is opened after sand core base cooled and solidified is good, finally takes out molding sand core from type chamber.
Molding sand core directly takes out from type chamber when being removed from the molds frequently with manpower, the big low efficiency of difficulty, especially
It is to sand core shown in Fig. 1, the slim chamber of sand core wall is deep, if undue force will lead to finished product sand core fragmentation, substantially reduces product
Qualification rate.
Summary of the invention
For the problems of the prior art, the present invention provides a kind of core mold with material returned function, and the core mold is logical
Crossing the pusher circle that setting is connected with die pad allows molding sand core to be easy to exit from type chamber, is avoided that finished product sand core exists
Chipping when taking-up, the qualification rate of product improves.
To realize the above technical purpose, the technical scheme is that：

Specific embodiment
In conjunction with Fig. 2, the specific embodiment that the present invention will be described in detail, but any limit is not done to claim of the invention
It is fixed.
As shown in Fig. 2, a kind of core mold with material returned function, including upper mold 1 and lower die 300, upper mold 1 and lower die 300
Structure forming cavity 2 after molding, 2 shape of type chamber and 01 shape of sand core are adapted, and are provided with pusher chamber 310, pusher in the lower die 300
Chamber 310 is located at 2 lower section of type chamber, and 310 top of pusher chamber communicates with 2 bottom part of type chamber, is equipped in pusher chamber 310 along pusher chamber
The 310 pusher circles 320 to move up and down, pusher circle 320 include liftout portion 321,321 shape of liftout portion and 01 bottom shape phase of sand core
It adapts to, 321 bottom of liftout portion is equipped with base portion 322；
The mold further includes die pad 500, connecting rod 400, die pad release link 600, pusher circle release link 800 and pushes away
Feed ring release link pressing plate 700；
The die pad 500 includes upper die pad 510 and bottom knockout plate 520, upper die pad 510 and bottom knockout plate 520 it
Between be connected and fixed by screw 530；Connecting rod 400 includes cylindric connecting rod interconnecting piece 410 and cylindric connecting rod positioning region
420,410 top of connecting rod interconnecting piece is connected with base portion 322, and 410 bottom end of connecting rod interconnecting piece passes through upper die pad 510, connection
Bar positioning region 420, which is located at, to be set in the second groove in bottom knockout plate 520, wherein the diameter of connecting rod positioning region 420, which is greater than, to be connected
The diameter of extension bar interconnecting piece 410, the diameter of the second groove are not less than the diameter of connecting rod positioning region 420；
The die pad release link 600 includes cylindric release link interconnecting piece 610 and cylindric release link positioning region 620,
610 top of release link interconnecting piece is in contact with 1 inner wall of upper mold, and 610 bottom end of release link interconnecting piece passes through upper die pad 510, resets
Bar positioning region 620, which is located at, to be set in the first groove in bottom knockout plate 520, wherein the diameter of release link positioning region 620 is greater than multiple
The diameter of position bar interconnecting piece 610, the diameter of the first groove are not less than the diameter of release link positioning region 620；
The pusher circle release link pressing plate 700 is set in 321 outer ring of liftout portion and is located at 321 bottom of liftout portion, pusher circle
Release link pressing plate 700 is equipped with third groove, and 800 top of pusher circle release link is in contact with 1 inner wall of upper mold, and pusher circle is multiple

Bar pressing plate 700 is connected.
The material returned resets principle：
When needing to take out molding sand core from core mold after sand core molding, mold is opened, die pad is pushed up
500, die pad 500 drives pusher circle 320 to move upwards by connecting rod 400, and pusher circle 320 pushes sand core to move upwards finally
By sand core ejection type chamber 2, in the process, die pad 500 drives the upward dry running of release link, and pusher circle 320 passes through pusher circle
Release link pressing plate 700 drives the upward null of pusher circle release link 800；Sand core molds after being removed, and upper mold 1 pushes release link and pushes away
Feed ring release link 800 resets downwards, when the screw 530 for connecting upper die pad 510 and bottom knockout plate 520 does not loosen, pushes away
Feed ring 320, which can both be driven under the action of release link by die pad 500, to be resetted, can also be in pusher circle release link 800
Lower driven by pusher circle release link pressing plate 700 of effect resets, when the screw 530 for connecting upper die pad 510 and bottom knockout plate 520
When loosening, pusher circle 320 can be driven under the action of pusher circle release link 800 by pusher circle release link pressing plate 700
It resets.
In conclusion the present invention has the following advantages that：
1. inventive die has the function of the material returned, make molding sand core can be with by the way that the pusher circle being connected with die pad is arranged
It is easy to exit from type chamber, is avoided that finished product sand core is chipping when taking out, the qualification rate of product improves；In addition, passing through
The release link being connected with die pad is set, and pusher circle can be returned to initial position when molding after sand core taking-up and carry out again next time
Pusher, so that continuous operations can be realized.
2. on the one hand the present invention can cooperate with release link to make to push away by setting pusher circle release link and pusher circle release link pressing plate
The more stable carry out Rapid reset of feed ring, on the other hand, when release link because the screw between upper die pad and bottom knockout plate occurs
When loosening and pusher circle can not be driven to reset by die pad again, in the effect of pusher circle release link and pusher circle release link pressing plate
Under, pusher circle still can reset, and can prevent from resetting pusher circle can not to influence sand next time
The size of sand core when core manufactures.
It is understood that being merely to illustrate the present invention above with respect to specific descriptions of the invention and being not limited to this
Technical solution described in inventive embodiments.Those skilled in the art should understand that still can be carried out to the present invention
Modification or equivalent replacement, to reach identical technical effect；As long as meet use needs, all protection scope of the present invention it
It is interior.
