In view of this, in fact be necessary to provide a kind of male model to pour in down a chimney cast gate, thus when solving above-mentioned IMR formed product easy de-oiling China ink and influence the problem of product quality and outward appearance towards printing ink.
[summary of the invention]
Therefore, the purpose of this utility model provides a kind of male model and pours in down a chimney cast gate, and easy de-oiling China ink reached the problem that influences yield and quality amount and outward appearance towards printing ink when utilization increased the cold burden design with solution IMR formed product in flow field end.
In order to achieve the above object, the male model that the utility model provides pours in down a chimney cast gate, and it is applied to the product of die for molding IMR processing procedure, and this male model pours in down a chimney cast gate and comprises:
Runner, this runner is for connecting the feeding-passage of die cavity;
Cold burden, it comprises cold burden district and empty avoiding space on every side thereof, and this cold burden district is communicated with the flow end of described runner, and this empty avoiding space outwards is being joined together to form of smooth curve extension and rounding off respectively by the two sides in this cold burden district.
Preferable, described cold burden is bilateral symmetry.
Preferable, the cross section in described cold burden district is formed by the semi arch of two symmetries and with the horizontal linear that its rounding off links together.
Preferable, the width of described cold burden district upper end open is greater than the width of described flow field end.
Preferable, bottom surface, described cold burden district is parallel with the bottom surface in described empty avoiding space.
Preferable, the distance between the bottom surface in bottom surface, described cold burden district and described empty avoiding space is greater than 2mm.
Compared to prior art, the utility model male model pours in down a chimney cast gate, solved in the IMR processing procedure when using male model to pour in down a chimney a little bigger tiltedly tip to prop up sheet and advance glue, because of cold burden makes the inhomogeneous problem that easily makes its de-oiling China ink and influence yield and quality towards printing ink of formed product, solved again simultaneously and poured in down a chimney a sheet and advance the problem that cold burden that glue produces influences product appearance, realized that the transfer printing that printing ink is complete on the top layer of product, makes ink lay combine closely with product subsurface.

[specific embodiment]
See also Fig. 2 and Fig. 3 illustrates, the male model that the utility model provides pours in down a chimney cast gate, and it is applied to the product 100 of die for molding IMR processing procedure, and this male model pours in down a chimney cast gate and comprises:
Runner 200, this runner 200 is for connecting the feeding-passage of die cavity;
Wherein, described cold burden 300 is bilateral symmetry.
Wherein, the cross section in described cold burden district 310 is formed by the semi arch 311 of two symmetries and with the horizontal linear 312 that its rounding off links together.
Wherein, the width S 1 of described cold burden district 310 upper end open is greater than the width S 2 of described runner 200 ends.
Wherein, 310 bottom surfaces, described cold burden district are parallel with 320 bottom surfaces, described empty avoiding space.
Wherein, between described 310 bottom surfaces, cold burden district and 320 bottom surfaces, described empty avoiding space apart from S3 greater than 2mm.
In IMR technology, its technological process is for to be positioned at prefabricated diaphragm in the mould, realizes injection moulding and printing ink transfer printing in moulding, because this diaphragm is attached to the master mold side, pours in down a chimney mould and advances glue in the male model side so mould is employing.See also Fig. 3 and illustrate, prop up sheet and advance glue with shaped article 100 for male model pours in down a chimney a little bigger tiltedly tip, owing to cold burden arranged in that the front end of runner 200 is residual behind the last mold forming, when the plastic cement of fusion injected die cavity, the cold burden of runner 200 front ends can at first arrive die cavity; Because the width of cold burden district 310 upper end open is greater than the width of runner 200 ends, the cold burden of this moment can at first flow in the slag well 410 of cold burden district 310 corresponding moulds 400, thereby cold burden is hoarded in cold burden district 310, to avoid influencing the moulding of subsequent product 100.After slag well 410 is filled with, plastic cement begins to overflow, because the frame of slag well 410 on the 320 corresponding moulds of empty avoiding space, the frame that is slag well 410 is a smooth curved surface, thereby thermoplastic is produced cushioning effect, the thermoplastic that overflows will be filled with die cavity with thermoplastic uniformly along the smooth curved surface of slag well 410 frames, can not fling to inject die cavity and produce phenomenon towards printing ink, thereby with product 100 moulding.
