Description

A kind of mould structure of automatic cut-out style big water gap

Technical field

The utility model relates to automated production field, more specifically, relates to a kind of mould structure of automatic cut-out style big water gap.

Background technology

After utilizing at present style big water gap to enter the pipe fitting product injection moulding of glue, generally all need manually to excise glue-feeder, under artificial production efficiency, can not realize full-automatic production.More advanced way is to utilize Hot runner Technology to carry out injection moulding at present, but for easy plastics or products of degrading such as some PVC, hot flow path technique is difficult to regulate, the easy carbonization of plastics during injection moulding, and hot flow path input cost is higher, and applicability is not strong.For these drawbacks, proposing the high and lower-cost scheme of a kind of applicability is necessary for addressing this is that.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model proposes a kind of mould structure of automatic cut-out style big water gap, do not increasing under the prerequisite of equipment, cost, realize and automatically cut off style big water gap.

To achieve these goals, the technical solution of the utility model is:

A kind of mould structure of automatic cut-out style big water gap, comprise solid plate, fixed mold core, take-up housing, slide block core, mavable module core, moving platen and plastic, described fixed mold core is fixed in solid plate framed, mavable module core is fixed in moving platen framed, also comprise push pedal, baffle plate, cutter and clamping plate, described slide block core is through baffle plate, and be pressed on take-up housing by clamping plate, the bore of described baffle plate is less than the maximum outside diameter of plastic, baffle plate is fixed in push pedal, on described baffle plate at corresponding style big water gap position fixed cutting tool, after making mould closure, active and inactive mold benevolence all must be forced sky to cutter, above-mentioned slide block core, mavable module core, fixed mold core dress closes rear participation moulding plastic.

Further, described cutter is the cutter of quenching stiffened, is provided with the edge of a knife on cutter.

Further, have the logical frame of a peripheral band gradient in the middle of described push pedal, described mavable module core periphery is with inclined-plane, and after matched moulds, gradient face and the mavable module core face of the logical frame of push pedal are suitable.

Further, described push pedal is connected with moving platen by limited screw.

Further, described push pedal is provided with for accepting under the product of the plastic that comes off and falls to force dead slot.

Further, described push pedal is connected with solid plate by positioning tie bar.

Further, described baffle plate is screwed in push pedal.

Compared with prior art, the beneficial effects of the utility model are:

1) not needing to increase in addition equipment or complex mechanism is set just to realize the automatic style big water gap that cuts off in mould, save the time of manually cutting the mouth of a river, save labour and enhance productivity.

2) applicability is high, can wipe out the style big water gap of various shapes, and the product that pipe fitting product enters glue as straight-through, elbow, threeway etc. by style big water gap is nearly all suitable for this programme.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described, but embodiment of the present utility model is not limited to this.

As Fig. 1, a kind of mould structure of automatic cut-out style big water gap, comprise solid plate 1, fixed mold core 2, positioning tie bar 3, push pedal 4, limited screw 5, baffle plate 6, clamping plate 7, take-up housing 8, slide block core 9, mavable module core 10, moving platen 11, plastic 12 and cutter 13, fixed mold core 2 is fixed in solid plate 1 framed, mavable module core 10 is fixed in moving platen 11 framed, slide block core 9 is through baffle plate 6, and be pressed on take-up housing 8 by clamping plate 7, the bore of baffle plate 6 is less than the maximum outside diameter of plastic 12, and baffle plate 6 is fixed in push pedal 4., cutter 13 is fixed on baffle plate 6, and after mould closure, active and inactive mold benevolence all must be forced sky to cutter 13; Cutter 13 in the present embodiment is to process through quenching stiffened, and is provided with the sharp edge of a knife.Wherein in push pedal 4, have the logical frame of a peripheral band gradient, mavable module core 10 peripheries are with inclined-plane, and after matched moulds, gradient face and the mavable module core face of push pedal 4 logical frames are suitable.Between push pedal 4 and moving platen 11, limited location screw 5 is connected, and push pedal 4 is connected by controlled interval pull rod 3 with solid plate 1, and baffle plate 6 is screwed in push pedal 4, and slide block core 9, through baffle plate 6, is pressed on take-up housing 8 by clamping plate 7.Slide block core 9, mavable module core 10, fixed mold core 2 dresses close rear participation moulding plastic 12.

The mould structure action of this real utility model is as follows:

Mould completes after injection moulding, when active and inactive mold is separated, first from A-A die joint, opens, until mavable module core 10 is while throwing off plastic 12 completely, more spacing by limited screw 5, now A-A die joint is opened S2.

Then B-B die joint is opened, until fixed mold core 2 is while departing from plastic 12 completely, spacing by controlled interval pull rod 3, now B-B die joint is opened S1.

Now hydraulic oil cylinder driving take-up housing 8 is loosed core, drive slide block core 9 to loose core, because plastic 12 is still held tightly on slide block core 9, and active and inactive mold die cavity has departed from plastic 12, plastic 12 can be followed 9 motions of slide block core, after motion S3, first the edge of a knife on cutter 13 cuts off style big water gap, style big water gap and gravitate separated with plastic 12 fallen down automatically, then oil cylinder continues to loose core until plastic 12 arrives baffle plate 6, because the gear of baffle plate 6 is young in the maximum outside diameter of plastic 12, so slide block core 9 continues to loose core, plastic 12 stops following loosing core, finally make slide block core 9 depart from plastic 12, after loosing core, because making plastic 12, Action of Gravity Field falls down.

Above-described embodiment of the present utility model, does not form the restriction to the utility model protection domain.Any modification of having done within spiritual principles of the present utility model, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present utility model.
