Description
Technical field
The utility model belongs to technical field of mold, relates in particular to a kind of side core-pulling injection mold.
Background technology
When plastic having sidewise hole, side direction convex-concave, side direction boss, being the energy demoulding smoothly, adopting side core-pulling device when injection mo(u)lding.In existing side core-pulling device, side core and side slide separately manufacture, complex structure, and assembling trouble, cost is high, and side core moves dumb, and the demoulding has some setbacks.
Utility model content
The purpose of this utility model is, for the problems referred to above, provides a kind of and side core and side slide are made all-in-one-piece side core-pulling injection mold.
For achieving the above object, the utility model adopts following technical scheme:
A kind of side core-pulling injection mold, comprise solid plate, moving platen and the side core between described solid plate and described moving platen, Angle Pin and latch segment described solid plate be equipped with, described side core is run through until inside described moving platen in the top of described Angle Pin, the inclined-plane of described latch segment and the contact of incline plane of described side core, wherein, baffle plate is equipped with in described moving platen side, described baffle plate and described side core are equipped with screw, described screw is socketed with spring.
Further, described screw-driving is fixed on described side core, and described screw can move axially relative to described baffle plate, and one end of described spring is against on described baffle plate, and the other end is against on the bolt of described screw.
Further, described moving platen is also inlaid with core.
Further, this side core-pulling injection mold also comprises push pedal, ejector pin retaining plate, push rod and sprue puller, and described push pedal is connected by soket head cap screw with described ejector pin retaining plate, and described push rod and described sprue puller are contained on described ejector pin retaining plate.
In order to sidewise hole, side direction convex-concave, side direction boss on the shaping plastic of energy, this practical core is provided with side core.In order to ensure the smooth demoulding, this practical core is provided with Angle Pin, screw and spring, and guide effect is played in the movement of Angle Pin to side core, and spring drives screw that side core is outwards loosed core in telescopic process, and baffle plate can the displacement of constrained side core.
Under matched moulds state, in order to prevent side core outwards movement under the action of the spring, the utility model core is provided with latch segment, can be stuck in the shoulder of side core, plays locking effect.
Solidifying for sprue material can pull out by sprue puller from sprue bush, and plastic, also with the effect of push rod, is released when die sinking by the sprue puller simultaneously in the utility model.
Implement side core-pulling injection mold of the present utility model and have following beneficial effect: side core and slide block make monoblock type, structure is simple, and assembling easily, can ensure the smooth demoulding with sidewise hole, side direction convex-concave, side direction boss plastic.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
In figure: 1, solid plate; 2, Angle Pin; 3, side core; 4, latch segment; 5, screw; 6, spring; 7, baffle plate; 8, moving platen; 9, core; 10, push pedal; 11, ejector pin retaining plate; 12, push rod; 13, sprue puller.
Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail below in conjunction with accompanying drawing.
Side core-pulling injection mold as shown in Figure 1, comprise cover half part and dynamic model part, cover half part comprises solid plate 1, solid plate 1 has inclined hole, Angle Pin 2 loads in this inclined hole, and Angle Pin 2 and inclined hole adopt interference fits, and one end of Angle Pin 2 is fixed on solid plate 1, the through side core 3 of the other end, arrives inside moving platen 8 always.Solid plate 1 is also equipped with latch segment 4, the inclined-plane of latch segment 4 just with the contact of incline plane of side core 3.
Baffle plate 7 is equipped with in the side of moving platen 8, and baffle plate 7 is fixed by screws on moving platen 8, leaves a segment distance between baffle plate 7 and side core 3, provides activity space when outwards loosing core to side core 3.
Screw 5 is screwed into inside side core 3 through block 7, and spring 6 is socketed on screw 5, and one end of spring 6 is against on the bolt of screw 5, and the other end is against on block 7, and when matched moulds state, spring 6 is in compressive state.
Push pedal 10 is connected by four soket head cap screws with ejector pin retaining plate 11, and four soket head cap screws lay respectively on four angles of push pedal 10, and push rod 12 and sprue puller 13 are contained on ejector pin retaining plate 11.
Particularly, under matched moulds state, side core 3 block 4 that is locked clamps, and spring 6 compression is against on block 7 by the bolt position of screw 5.When plastic injection mo(u)lding, mould die sinking, moving platen 8 retreats, while side core 3 and solid plate 1 unclamp, side core 3 outwards starts to loose core under the effect of spring 6, when side core 3 move to contact with baffle plate 7 time, because the position-limiting action side core 3 being subject to baffle plate 7 stops mobile, at this moment complete side core-pulling action.
While moving platen 8 retreats, sprue puller 13 retreats together along with moving platen 8, and solidifying for sprue material pulls out by sprue puller 13 from sprue bush.
When dynamic model part stops retreating, following push pedal 10 promotes ejector pin retaining plate 11 and moves to the direction at plastic place, and push rod 12 and sprue puller 13 withstand plastic toward extrapolated, and plastic departs from core 9 and completes the demoulding.
Wherein, the distance between baffle plate 7 and side core 3 will calculate according to mould opening stroke, ensures that side core 3 has enough mobile spaces.
Side core-pulling mechanism of the present utility model is not only applicable to single die joint mould, is equally applicable to Two_Parting_Surface Mould yet.
The utility model is not limited to above-mentioned detailed description of the invention; anyone can draw other various forms of products under enlightenment of the present utility model; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
