The side of template is connected with bolt adjusting part, and the sleiding form can be led described in the promotion lower edge of the bolt adjusting part
It is moved in runner.
Preferably, the bolt adjusting part includes hold-doun nut, the outer wall of the hold-doun nut and the cover half mode
Or the inner wall of the dynamic model mode connects, and adjustment bolt, the adjustment bolt and the fixation are provided in the hold-doun nut
Nut is using threaded connection.
Preferably, the side of the adjustment bolt is equipped with positioning shoulder, and the positioning shoulder is inserted into the sleiding form, described
A variable cast gate cavity is formed between sleiding form and the cover half mode or the dynamic model mode, described in positioning shoulder promotion
Sleiding form moves in the variable cast gate cavity.
Preferably, the other side of the adjustment bolt be equipped with protective cover, the protective cover removably with the adjustment spiral shell
It tethers and connects, the protective cover can stretch into the hold-doun nut.
Preferably, one end of the part die cavity is additionally provided with overflow launder.
Preferably, the side of the dynamic model mode is provided with shunting vertebra, the shunting vertebra stretch into the sprue and with
The expects pipe offsets.
The invention has the advantages that:The quick variable cast gate structure of cast die of the present invention is poured without weld mold
Mouthful, the big minor adjustment that cast gate is completed using sleiding form and the collaboration of bolt adjusting part is worked, and is provided production efficiency, is extended mold
Service life.

Specific implementation mode
As shown in Figs 1-4, it is a kind of quickly variable cast gate structure of cast die of the present invention, including cover half mode 1 and dynamic
Mould mode 2, is equipped with part die cavity 3 between cover half mode 1 and dynamic model mode 2, part die cavity 3 is connected with expects pipe 4 and runner system
System, expects pipe 3 are arranged on cover half mode 1, and flow passage system is arranged between cover half mode 1 and dynamic model mode 2, and flow passage system includes
Sprue 5 and the ingate 6 being connected to 3 one end of part die cavity, sprue 5 is interior to be equipped with a sleiding form 7, sleiding form 7
Side is connected with bolt adjusting part, and sleiding form 7 can move under the promotion of bolt adjusting part along sprue 5.
Bolt adjusting part includes hold-doun nut 8, outer wall and cover half mode 1 or the inner wall of dynamic model mode 2 of hold-doun nut 8
It connects, adjustment bolt 9 is provided in hold-doun nut 8, adjustment bolt 9 is used with hold-doun nut 8 and is threadedly coupled.
The side of adjustment bolt 9 is equipped with positioning shoulder 10, and positioning shoulder 10 is inserted into sleiding form 7, sleiding form 7 and cover half mould
A variable cast gate cavity 11 is formed between benevolence 1 or dynamic model mode 2, positioning shoulder 10 pushes sleiding form 7 in variable cast gate cavity 11
Interior movement.
The other side of adjustment bolt 9 is equipped with protective cover 12, and protective cover 12 is removably connect with adjustment bolt 9, specifically,
