The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of front mould water dividing gap structure, comprise A plate 13, chamber 10, core 11, push pedal 14, B plate 15 and backing plate 16, front mould inside contracts mold insert 2 and is arranged on chamber 10 and A plate 13, be arranged on backing plate 16 rear mold fixedly mold insert 4 be in B plate 15, front mould inside contracts mold insert 2 end faces and is provided with avoiding hollow groove, and position limiting structure is installed in avoiding hollow groove, rear mold fixedly is equipped with the flexible mold insert 3 of rear mold in mold insert 4, and spring 5 is arranged on the flexible mold insert of connection rear mold 3 bottoms on backing plate 16.The processing front mould inside contracts the installing hole of mold insert 2 on A plate 13 and chamber 10, and hole and front mould inside contract mold insert 2 cunnings and join.Inside contract on mold insert 2 at front mould and do stroke limit with limited block 1, locking nut 6 is fixed on A plate 13, the flexible mold insert 3 dependence rear molds of the rear mold fixedly interior counterbore of mold insert 4 are done the travel limits that rear mold is stretched mold insert 3, and the flexible mold insert 3 of rear mold relies on the unilateral thrust of springs 5 to complete flexible.
Fig. 2 is that the mouth of a river is cut and cut the work schematic diagram, when die sinking, mould forces to make stripper plate 12 and A plate 13 to be opened under the effect that is subjected to other external force, simultaneously front mould inside contracts mold insert 2 and the flexible mold insert 3 of the flexible mold insert 3 of rear mold mandatory promotion rear mold under the effect of spring 5 unilateral thrusts and front mould and inside contracts mold insert 2 and up move, all the promotion that is subjected to same power because front mould inside contracts the flexible mold insert 3 of mold insert 2 and rear mold, can carry secretly and up move together with runner Jiao Kou thereby make front mould inside contract the flexible mold insert 3 of mold insert 2 and rear mold, walk at last spacing distance., cut so cutting of the mouth of a river completed in this time relative motion simultaneously because chamber 10 and 11 two dies of core also are in closure state at this.
Fig. 3 is mould die sinking schematic diagram, and the mould of this moment pulls on exoneration flitch 12 and deviates from regrinding-material with A plate 13 under the effect of injection machine machinery power.Stripper plate 12 stops opening with A plate 13 when stripper plate 12 is opened to other stopping means, and injection machine still continued to pull open and made mould A plate 13, B plate 15 and chamber 10 be forced to pull open with core 11 this moment.Open at last the opening stroke to injection machine.
Fig. 4 is that the mould die sinking ejects schematic diagram, mould is forced to promote forward under the effect of injection machine push rod mechanical force, promote forward together with mould accessory that push pedal 14 and core 11 is connected and fixed, thimble 8 thereby make, make plastic products 7 and inlet flow channel be pushed out.
Fig. 5 mould ejection product schematic diagram that drops, last plastic products 7 and runner are under the own wt effect and in the postorder operation that drops.
The course of work of the present utility model is:
When injection moulding machine mould open, mould stripper plate 12 is forced to first open under the interference of external force with A plate 13, just front mould inside contracts and is carrying inlet flow channel secretly under the effect that mold insert 2 and the flexible mold insert 3 of rear mold also be subject to spring 5 unilateral thrusts simultaneously and up move when stripper plate 12 and A plate 13 are opened, the chamber 10 of this moment is in closure state with the PL face of core 11, and product is motionless and reached the process that cut away at the mouth of a river in die cavity.Front mould inside contracts mold insert 2 and rear mold is stretched mold insert 3 in limited block 1 and the fixedly promotion of spacing lower prevention spring 5 elastic force of mold insert 4 of rear mold.Then the effect bed die in injection machine machinery power pulls on exoneration flitch 12, and stripper plate 12 walks to after certain stroke because the impact that is subjected to certain stopping means stops continuing to pull open.This moment, mould was subject to the enforceable PL of the pulling open face of effect of injection machine machinery power, and chamber 10 and core 11 are separated.Injection machine stops pulling open after reaching opening stroke.Mould make under the effect that is subjected to injection machine push rod thrust mould push pedal 14 core 11 and thimble 8 release simultaneously product and runner, completed the process of whole work.
The above is only an example of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
