Bridging type cast gate, its side connecting passage, opposite side is located at the upper cover of shaping keyboard on male die insert, and described bridging type cast gate also has the false cast gate of bending downwards;
Some thimbles, its one end is fixed in upper ejector plate, and the other end runs through male template and male die core and heads on the upper cover of described keyboard;
Material grasping pin, its one end is located on bottom plate, the other end runs through the lower end that the lower liftout plate of mould, upper ejector plate, male template and male die insert abut described bridging type cast gate, the position of the corresponding upper ejector plate of described material grasping pin is provided with countersunk head, be provided with emptiness avoiding hole in described upper ejector plate and lower liftout plate, described countersunk head is located in emptiness avoiding hole and with the lower surface of emptiness avoiding hole has empty avoiding distance.
Alternatively, described material grasping pin breaking is located on described bottom plate.
Alternatively, the lower end of described bridging type cast gate is provided with hook breach, and one end that described material grasping pin abuts described bridging type cast gate is accordingly provided with projection and coordinates with described hook breach.
Compared to prior art, automatic Break Gate Structure of the present utility model, when the upper cover of shaping keyboard, cow glue powder is substituted by using bridging type cast gate, and by being provided with countersunk head delayed goring on material grasping pin, the upper cover of bridging type cast gate and keyboard and male die core are completed be separated, thus it is easily broken when ejecting to solve cow glue powder, the problem not easily ejected.

[detailed description of the invention]
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, wherein Fig. 1 depicts the schematic diagram of the utility model automatic Break Gate Structure, and Fig. 2 depicts the schematic perspective view of the utility model automatic Break Gate Structure local, and Fig. 3 depicts the sectional view of Fig. 2.
Automatic Break Gate Structure of the present utility model, it is applied to the upper cover 10 of die for molding keyboard, described mould comprises bottom plate 11, lower liftout plate 12, upper ejector plate 13, male template 14, male die core 15, mother module core 16, caster 17 and runner 18, in the present embodiment, described automatic Break Gate Structure comprises:
Male die insert 19, it is located in described male die core 15;
Bridging type cast gate 20, its side connecting passage 18, opposite side is located at the upper cover 10 of shaping keyboard on described male die insert 19, and described bridging type cast gate 20 also has the false cast gate 21 of bending downwards, and described false cast gate 21 is for playing balanced action;
Some thimbles 22, its one end is fixed in upper ejector plate 13, and the other end runs through male template 14 and male die core 15 and heads on the upper cover 10 of described keyboard;
Material grasping pin 23, its one end is located on bottom plate 11, the other end runs through the lower end that the lower liftout plate 12 of mould, upper ejector plate 13, male template 14 and male die insert 19 abut described bridging type cast gate 20, the position of the corresponding upper ejector plate 13 of described material grasping pin 23 is provided with countersunk head 24, described upper ejector plate 13 and lower liftout plate 12 are provided with emptiness avoiding hole 25 accordingly, and described countersunk head 24 has empty avoiding distance with the lower surface of this emptiness avoiding hole 25.
Wherein, in order to accept pressure during injection moulding, the breaking of described material grasping pin 23 is located on described bottom plate 11.
Wherein, described material grasping pin 23 is in order to abut with described bridging type cast gate 20 better, and the lower end of described bridging type cast gate 20 is provided with hook breach, and one end that described material grasping pin 23 abuts described bridging type cast gate 20 is accordingly provided with projection and coordinates with described hook breach.
Refer to shown in Fig. 4, it depicts the schematic diagram that first of the utility model automatic Break Gate Structure local ejects state.After the upper cover 10 of keyboard is shaping, in ejection process, upper ejector plate 13 and lower liftout plate 12 drive described thimble 22 to eject, the upper cover 10 of shaping keyboard upwards ejects, and the countersunk head 24 of material grasping pin 23 is because having empty avoiding distance with the lower surface of described emptiness avoiding hole 25, therefore material grasping pin 23 delayed goring, bridging type cast gate 20 transfixion, and under the pulling force effect of the false cast gate 21 of bridging type cast gate 20, described bridging type cast gate 20 is separated with the upper cover 10 of described keyboard.
Refer to shown in Fig. 5, it depicts the schematic diagram that second of the local of the utility model automatic Break Gate Structure ejects state.After bridging type cast gate 20 is separated with the upper cover 10 of described keyboard, when the countersunk head 24 of material grasping pin 23 contacts the lower surface of described emptiness avoiding hole 25, described material grasping pin 23 ejects jointly with upper ejector plate 13, lower liftout plate 12 and thimble 22, bridging type cast gate 20 ejects by described material grasping pin 23, makes bridging type cast gate 20 be separated stripping action with the male die insert 19 in male die core 15.In addition, can also continue to do twice and identical eject action after this time has ejected, prevent the bridging type cast gate 20 incomplete situation that drops once in a while from occurring, prevent bridging type cast gate 20 pressing mold.
Compared to prior art, automatic Break Gate Structure of the present utility model, when the upper cover 10 of shaping keyboard, cow glue powder is substituted by using bridging type cast gate 20, and by being provided with countersunk head 24 delayed goring on material grasping pin 23, bridging type cast gate 20 is completed with shaping keyboard top cover 10 and male die core 15 be separated, thus it is easily broken when ejecting to solve cow glue powder, the problem not easily ejected.
