Description

A kind of ejecting mechanism of mould

[technical field]

The utility model belongs to mould design and manufacturing field, the particularly a kind of ejecting mechanism of mould in the machine industry.

[background technology]

Current, the plastic products quantity of utilizing injection mould to produce is various, because its production efficiency height, product quality are better, so, range of application is very extensive, and the shape of product also becomes increasingly complex, thereby, make Mould design and manufacture difficulty increase, many product requirement moulds can finish such as secondary eject, a plurality of actions such as first backhaul.

Mostly the secondary ejecting mechanism that people such as Hua Chang in the wrong and 5 foundations delivered in the design of plastics mould in 1993 is drag hook type, two groups of top board mechanisms, or even add hydraulic pressure or electrical equipment and (bend Hua Chang, 5 found the state. plastics mould design [M] .1993 November the 1st edition, P110), yet, the complex structure that these mechanisms have breaks down easily, reduces production efficiency maintenance frequency thereby cause more; Have in use,, thereby injure product owing to wearing and tearing cause the asynchronous of ejector member to eject.

[utility model content]

The utility model provides a kind of ejecting mechanism of mould, and is simple in structure, ejects synchronously, do not injure product.

The technical scheme that the utility model adopted is: a kind of ejecting mechanism of mould, comprise connecting rod, the lever that is connected with connecting rod with the fixedly connected push rod of connecting rod, by first screw, and the side plate that contacts with lever discontinuity, wherein, connecting rod, push rod and lever are arranged on the dynamic model, side plate is arranged on the quiet mould, described lever one end is fixed on the dynamic model, the other end is connected with connecting rod by first screw, described lever is provided with long and narrow through hole, and described first screw passes this through hole and is connected with connecting rod.

As preferred embodiment of the present utility model, further comprise the pressing plate that is fixed on the dynamic model and intersects with connecting rod;

As preferred embodiment of the present utility model, described pressing plate is vertical with connecting rod to be provided with;

As preferred embodiment of the present utility model, described side plate comprise the vertical component effect that be arranged in parallel with connecting rod and with the vertical horizontal contact section that is provided with and contacts of vertical component effect with the lower surface discontinuity of lever;

As preferred embodiment of the present utility model, has the gap between described connecting rod and the dynamic model surface.

The ejecting mechanism of the utility model mould has the following advantages at least: 1. this mechanism can increase by one ejecting outside the action of injector and ejects action, can be used for secondary ejecting mechanism, also can be used for generally ejecting, and has multipurpose character; 2. the spinning movement of lever is converted into the translation action of top board, and the side plate move distance do not limit by leverage, adaptability is strong, security good; 3 compare with secondary ejecting mechanism in the past, can avoid ejecting asynchrony phenomenon, prevent that goods from damaging; Also simplified mould structure, and moving component is few, each component shape is simple and assembly precision is less demanding, can reduces damage probability, increase the service life, reduce cost.

[specific embodiment]

See also shown in Figure 1ly, the ejecting mechanism of the utility model mould comprises connecting rod 3, the push rod (indicate) fixedly connected with connecting rod 3, the lever 4 that is connected with connecting rod 3 by first screw 2, the pressing plate 6 of fixedlying connected with connecting rod 3, and side plate 5.

Described connecting rod 3 is arranged on the dynamic model, form certain angle between lever 4 and the connecting rod 3, when original state, this angle in the present embodiment is 90 degree, described lever 4 is provided with long and narrow through hole, and described first screw 2 passes this through hole and is fixed on the connecting rod 3.So, lever 4 one ends are fixed on the dynamic model by second screw 1, and the other end is connected with connecting rod 3 by first screw 2.

Pressing plate 6 is fixedlyed connected all the time with connecting rod 3 vertical settings, and with dynamic model, so, guarantees that connecting rod 3 moves all the time in through hole, keeps whole motion stability.

Side plate 5 is fixed on the quiet mould, is the inverted T-shaped structure, comprise the vertical component effect 51 that be arranged in parallel with connecting rod 3 and with vertical component effect 51 vertically disposed horizontal contact section 53.

Please continue to consult shown in Figure 1, during original state, side plate 5 is positioned at lever 4 belows; When dividing mould, quiet mould drives side plate 5 and moves up, horizontal contact section 53 until side plate 5 contacts with the lower surface of lever 4, at this moment, quiet mould continues motion up, at this moment, because side plate 5 applies effect down in lever 4, thereby, make that lever 4 is that the axle center rotates with second screw 1, break away from lever 4 until side plate 5, in the process that lever 4 rotates, connecting rod 3 is driven does horizontal movement at above-below direction, so, the push rod of fixedlying connected with connecting rod 3 ejects thing to be ejected, and ejects action thereby finish.

In the present embodiment,, can control the branch mould distance that ejects between preceding quiet mould and the dynamic model, be as H among Fig. 1 and eject preceding branch mould distance, to satisfy some process requirements by the length of control link 3.

Moreover, in the present embodiment, can use the screw of being with shoulder as second screw 1 of axis of rotation, also can install axle sleeve in addition additional; In addition, the distance that connecting rod 3 and die surface are small at interval is as Fig. 3, connecting rod 3 and die surface distance L, so, both can be to have guaranteed quality of fit enough between first screw and the lever, also can guarantee between first screw and the mould cannot not be connected firmly looseningly and operational excellence without hindrance.

Ejecting by this mechanism of mould realize, that is eject in injector and to have increased by one outside the action and eject action, can be used for secondary ejecting mechanism, and can avoid the asynchrony phenomenon that ejects that exists in the common secondary ejecting mechanism, and prevents that product is impaired.

The above only is a kind of embodiment of the present utility model, it or not whole or unique embodiment, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
