Abstract

The utility model provides a mould structure convenient to finite space breaks away from all around barb drawing of patterns, it includes slider and four public mould taper pins in a public mould benevolence, four public moulds, and slider and public mould taper pin match each other in public mould and the public mould. The male die is provided with an inner sliding block module, the shifting pin of the sliding block in the male die is arranged on the bearing plate, after the die is opened, the four shifting pins on the bearing plate drive the inner sliding block to actuate to reach the barb area which is separated from four corners, and simultaneously the four oblique pins are given to vacate the moving space so as to separate from the barbs in the whole circumference.

Description

Be convenient to the mould structure that the confined space breaks away from complete all barb demouldings

Technical field

The utility model relates to a kind of ejection shaping die, particularly a kind ofly is convenient to the mould structure that the confined space breaks away from complete all barb demouldings.

Background technology

At present electronics, electric type plastic cement products shape are various, cooperatively interacting between the plastic cement products just has the design of grab, and these grabs just form barb on plastic cement products, when making barb, normal generation is the problem of the demoulding normally, and need the mould structure of special shape to realize this moment mostly.

Prior art is when mould is designed the male model slide block and utilizes upper mounted plate and switch-plate to break stub bar when handling the barb problem, drives finger, and finger drives slide block again and realizes, its design feature is not interference of barb, can use the slide block moulding.The technology of another kind of processing barb problem is the design oblique top, utilizes the motion of liftout plate up and down to drive the relative motion of oblique top and then make barb break away from mould, and mechanical feature is to need intensity and the stroke that enough spaces guarantee oblique top.

Therefore, the utility model promptly proposes a kind of mould structure that the confined space breaks away from complete all barb demouldings of being convenient to, and to overcome above-mentioned these problems, concrete framework and embodiment thereof will be specified in down.

Summary of the invention

Main purpose of the present utility model is providing a kind of mould structure that the confined space breaks away from complete all barb demouldings of being convenient to, and it is to utilize the male model inner slide to detach four barbs on the angle earlier to vacate space to taper pin simultaneously, thereby detaches complete all barbs.The mould of complete all barbs of the present utility model is steadily smooth in motion, and institute takes up space less, is used for scale of mass production.

In order to achieve the above object, the utility model provides a kind of mould structure that the confined space breaks away from complete all barb demouldings of being convenient to, and comprising:

One male model benevolence, with a plurality of male model inner slides and male model taper pin coupling, this male model benevolence is provided with an inner slide module, and a finger of these a plurality of male model inner slides is located on the board;

Barb is located on male model inner slide and the male model taper pin, after this mould structure is opened, drive this finger, make these a plurality of male model inner slides break away from the barb of the band of position, four angles earlier by this board, vacate movably space for simultaneously this male model taper pin, thereby detach complete all barbs;

Wherein, a taper pin push rod of this male model taper pin passes a upper ejector plate, promote this upper ejector plate or once liftout plate can drive this taper pin push rod, and then make this male model taper pin break away from this a plurality of barbs, just can be release after the full week disengaging of these a plurality of barbs.

Describedly be convenient to the mould structure that the confined space breaks away from complete all barb demouldings, wherein, this finger is locked on this board, and at least one back stitching in the mould all designs a corresponding briquetting, and at least one back stitching spring can prevent that this upper ejector plate and this time liftout plate from retreating.

The beneficial effects of the utility model: after mould is opened, drive the start of male model inner slide by four fingers on the board and reach the purpose that breaks away from four angle barbs earlier, vacate space for simultaneously four male model taper pins, thereby detach complete all barbs; The mould of complete all barbs of the present utility model, steadily smooth in motion, institute takes up space less, is convenient to scale of mass production.

The beneath specific embodiment that relies on illustrates in detail, when the effect that is easier to understand the purpose of this utility model, technology contents, characteristics and is reached.

The specific embodiment

The utility model provides a kind of mould structure that the confined space breaks away from complete all barb demouldings of being convenient to, please refer to Figure 1 and Figure 2, the mould of being convenient to make complete all barbs of the present utility model comprises a male model benevolence 200, four male model inner slides 300,301,302,303 and male

model taper pins

80,81,82,83; Male model benevolence 200 can be mated mutually with male model inner slide 300,301,302,303 and male

model taper pin

80,81,82,83.During matched moulds, resetted and compressed by the T-slot of finger 304, the below design of each male model inner slide 300,301,302,303 has the one-sided guide rail 305,306 of inner slide, allows male model inner slide 300,301,302,303 move in the above.

When handling the barb problem, please refer to Fig. 3, Fig. 4 and Fig. 5, board 5 is locked on the bottom plate 9 with spacer block 6, and upper ejector plate 7 lockings are on following liftout plate 8, taper pin push rod 84 passes upper ejector plate 7, complete all barbs 12 designs of product 11 are on male model inner slide 300,301,302,303 and male

model taper pin

80,81,82,83, and male model benevolence 200 and male model plate 4 and board 5 lockings are also spacing with contour screw 50.Finger 304 is locked on the board 5, and at least one back stitching 13 in the mould all designs a corresponding briquetting 14, and liftout plate 8 retreats under at least one back stitching spring 10 effects in case upper ejector plate 7 reaches down.

Can find out that in Fig. 5 spacer block 6 is connected with a guide pillar 20, this guide pillar 20 passes board 5 and male model plate 4, is coated with one deck guide pillar lining 21 in guide pillar 20 peripheries to separate with board 5 and male model plate 4.

Please refer to Fig. 6, after mould was opened, feature die separated, and product is stayed the male model side, separated with board 5 along with opening stroke strengthens back male model plate 4 under the outside link effect.Board 5 drives 304 motions of four fingers, finger 304 makes male model inner slide 300,301,302,303 along moving in four angles of product 11 by T-slot, be subjected to the spacing of contour screw 50 after male model plate 4 and board 5 separate a segment distance, male model inner slide 300,301,302,303 breaks away from product barbs 12 at this moment.

Please refer to Fig. 7 and Fig. 8, upper and

lower liftout plate

7,8 begins to promote, and four taper pin push rods 84 are pushing away 80,81,82,83 motions of male model taper pin, and male

model taper pin

80,81,82,83 moves along breaking away from barb 12 directions, ejects product simultaneously.

Only the above is preferred embodiment of the present utility model only, is not to be used for limiting the scope that the utility model is implemented.So be that all equalizations of doing according to described feature of the utility model application range and spirit change or modification, all should be included in the claim of the present utility model.
