Abstract
The invention relates to the technical field of mold forming, in particular to an interval pop-up type demoulding device. Compared with the prior art, the interval pop-up type demoulding device adopts the structure of two parting surfaces, the impression and core of the demoulding device are both provided with external drums, a main parting surface is firstly opened when a mold is opened to ensure the product to stay in a mobile mould impression, and then a secondary parting surface is opened. As the slope of the external drum on the impression is less than that of the external drum on the core, when a push plate is away from a fixing plate 10mm, the cavity between the core and the product is larger than the external drum arranged on the impression and a thimble can be used to easily eject the product which is separated from the core out of the impression; as the external drum is previously formed on the product, the demoulded product is flat after forming, the reshaping process is eliminated; and the quality is stable, and the production efficiency is greatly increased.
Description
Technical field
The present invention relates to the mould molding technical field, particularly a kind of interval pop-up type demoulding device.
Background technology
Along with the development of industrial technology, because plastic material has advantages such as shaped article is fast, the prices of raw and semifnished materials are low, plastic material more and more is applied in the industrial production field, and as various capacitor shells etc., these all need the former of mould of plastics.
The product that certain structures is more special, as some band ear products, its die joint also is different from the die joint of mill run, its die joint of this product can only be located at the product outer bottom, the stripping means of this product of the prior art is: for guaranteeing carrying out smoothly of the demoulding, the molding gradient of die cavity must go up size down, and the product peristome can not have external drum (it is the indent that produces when product shrinks in order to offset that external drum mainly acts on), otherwise can produce the back taper phenomenon, can wear top, product bottom during the thimble demoulding, form product rejection.And the product that the mould molding that can not do external drum comes out can produce serious indent after the demoulding, in order to guarantee to allow this indent not influence the use of product, behind product stripping, also to spend and manually product be carried out shaping with the shaping tool, so not only expend a large amount of human and material resources, reduce production efficiency greatly, but also exist a lot of defective products.
Summary of the invention
For solving band ear existing defective of product stripping device and problem in the prior art, provide a kind of interval pop-up type demoulding device.
The technical scheme that the present invention is adopted for its technical problem of solution is: interval pop-up type demoulding device of the present invention comprises dynamic model and cover half, dynamic model is provided with die cavity, fuse, brute spring, fixed head and thimble, one push pedal is set between cavity plate and fixed head, nitrogen spring is installed in cover half, the elastic force of nitrogen spring is greater than the elastic force of brute spring, under the effect of nitrogen spring elastic force, between dynamic model and cover half, form a main die joint, between cavity plate and push pedal, form die joint one time, on die cavity and fuse, be equipped with external drum, the gradient of the external drum on the die cavity is less than the external drum gradient on the fuse, the gradient of the external drum on the die cavity is 0.84 °, external drum gradient on the fuse is 2.82 °, and after the distance between fixed head and the push pedal was 10mm, the cavity between fuse and the product was greater than the set external drum amount of die cavity.
The invention has the beneficial effects as follows: compared with prior art, interval pop-up type demoulding device of the present invention adopts two die joint structures, master's die joint is opened earlier when die sinking, guarantee that product stays in the dynamic model die cavity, and then open time die joint, because the external drum gradient on the die cavity is less than the external drum gradient on the fuse, therefore after fixed head 10mm is left in push pedal, cavity between fuse and the product is greater than the set external drum amount of die cavity, the product that thimble just can easily have been backed out fuse ejects in die cavity, and the product after the demoulding is because of doing external drum in advance, and outward appearance is straight after its moulding, save the workload and the steady quality of shaping, improved production efficiency greatly.
Description of drawings
Below in conjunction with the drawings and specific embodiments interval pop-up type demoulding device of the present invention is described further.
Fig. 1 is the structural representation of interval pop-up type demoulding device of the present invention.
The specific embodiment
As shown in Figure 1, interval pop-up type demoulding device of the present invention comprises dynamic model 10, cover half 20 and push pedal 30.Dynamic model 10 is provided with die cavity 11, fuse 12, brute spring 13, fixed head 14 and thimble 15.Push pedal 30 is arranged between die cavity 11 plates and the fixed head 14.Two nitrogen springs 21 are installed in cover half 20, the elastic force of nitrogen spring 21 is greater than the elastic force of brute spring 13, when die sinking, because the elastic force of nitrogen spring 21 is greater than the elastic force of brute spring 13, therefore under the effect of nitrogen spring 21 elastic force, under brute spring 13 effects, between die cavity 11 and push pedal 14, form die joint 2 one time then.On die cavity 11 and fuse 12, be equipped with external drum, it is in order to offset the indent that product produces when the demoulding after-contraction that external drum mainly acts on, the gradient of the external drum on the die cavity 11 is generally 0.84 °, external drum gradient on the fuse 12 is generally 2.82 °, and the external drum gradient on the die cavity 11 is less than the external drum gradient on the fuse 12.
As shown in Figure 1, in the work of reality, in the die sinking process, because the elastic force of nitrogen spring 21 is greater than the elastic force of brute spring 13, therefore under the effect of nitrogen spring 21 elastic force, between dynamic model 10 and cover half 20, form a main die joint 1 earlier, this moment, product 0 all kept relative static with die cavity 11 and push pedal 30, cover half 20 breaks away from die cavities 11 at this moment, after cover half 20 breaks away from die cavity 11, because the elastic force effect of brute spring 13, between die cavity 11 and push pedal 14, form die joint 2 one time, die cavity 11 breaks away from fuse 12 1 segment distances with product, after the distance between die cavity 11 and the push pedal 14 is 10mm, after just die cavity 11 distance that breaks away from fuse 12 with product is 10mm, because the external drum gradient on the die cavity 11 is less than the external drum gradient on the fuse 12, therefore the amount of space of the external drum that on the space between fuse 12 and the product will be greater than die cavity 11, is provided with, just can easily in die cavity 11, eject product 0 with thimble at this moment, and the back taper phenomenon can not take place, because the product after the demoulding is because of doing external drum in advance, can not produce the indent phenomenon after its demoulding, outward appearance is straight after its moulding, save the workload and the steady quality of shaping, improved production efficiency greatly.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
