Description

The mould structure that a kind of arc angled-lift splits is loosed core

Technical field

The utility model relates to the technical field of structures of metal die-casting mold, plastic injection mould, is specially the mould structure that a kind of arc angled-lift splits is loosed core.

Background technology

Using metal die-casting mold, plastic injection mould to produce in the process of product, when the shaping of product side or hole shaping area larger time, the form of slide block slide guide should be adopted.And when side shaping area comparatively large and with certain inclination angle time, existing angled-lift splits core-pulling die structure needs the slide block oblique angle that design is larger, to obtain corresponding pulling distance.But the oblique angle of angled-lift splits is excessive, can make slide block release product certain in a flash, easily produce unexpected inclination, very easily damage angled-lift splits.

Summary of the invention

For above-mentioned deficiency, the mould structure that the utility model provides a kind of arc angled-lift splits to loose core, it guarantees after dynamic, cover half are opened, angled-lift splits can obtain larger pulling distance, accurately complete and loose core, and stable action is reliable, not easily produce unexpected inclination and be damaged to the side of angled-lift splits.Mould structure is simple, and cost of manufacture is low.

The technical scheme realizing the utility model object is such:

The mould structure that arc angled-lift splits is loosed core, comprises dynamic model and cover half, forms die cavity between dynamic model, cover half, and described dynamic model comprises angled-lift splits, dynamic model frame, moving clamping plate and dynamic mould core fixed head, unlike the prior art:

The arc angled-lift splits of described angled-lift splits to be hypotenuse be circular arc, the circular arc guide runner that the hypotenuse center of circle that described dynamic model frame is provided with the center of circle and arc angled-lift splits coincides, the radian of circular arc guide runner matches with the radian of arc angled-lift splits hypotenuse;

Also comprise

Push rod, push rod is through moving clamping plate and dynamic mould core fixed head, and one end of push rod and the lower surface of arc angled-lift splits are abutted against.

Circular arc hypotenuse on described arc angled-lift splits is provided with stopper slot, and dynamic model frame is provided with the banking pin corresponding with stopper slot, deviates from circular arc gathering sill in dynamic model frame to prevent arc angled-lift splits.

Adopt the mould structure that this arc angled-lift splits is loosed core, after injection moulding or die casting complete, arc angled-lift splits, under the effect of push rod, is movement in a curve along guide runner.Thus while arc shaped slider separates to both sides, certain inclination occurs slowly, avoid significantly because rolling suddenly, the flimsy shortcoming of angled-lift splits, effectively protects mould.Can guarantee that angled-lift splits can obtain larger pulling distance, accurately completes and looses core after dynamic, cover half are opened, and stable action is reliable, not easily produces unexpected inclination and be damaged to the side of angled-lift splits.Mould structure is simple, and cost of manufacture is low.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model content is further described, but is not to restriction of the present utility model.

With reference to Fig. 1 Fig. 2, the mould structure that a kind of arc angled-lift splits is loosed core, comprise dynamic model and cover half, die cavity is formed between dynamic model, cover half, described dynamic model comprises angled-lift splits, dynamic model frame 6, moving clamping plate 8 and dynamic mould core fixed head 7, the arc angled-lift splits 5 of described angled-lift splits to be hypotenuse be circular arc, the circular arc guide runner 12 that the hypotenuse center of circle that described dynamic model frame 6 is provided with the center of circle and arc angled-lift splits 5 coincides, the radian of circular arc guide runner 12 matches with the radian of arc angled-lift splits 5 hypotenuse;

Also comprise

Push rod 9, push rod 9 is through moving clamping plate 8 and dynamic mould core fixed head 7, and one end of push rod 9 and the lower surface of arc angled-lift splits 5 are abutted against.

Circular arc hypotenuse on described arc angled-lift splits 5 is provided with stopper slot 4, and dynamic model frame 6 is provided with the banking pin 13 corresponding with stopper slot 4, deviates from circular arc guide runner 12 in dynamic model frame 6 to prevent arc angled-lift splits 5.

Particularly, the mould structure that arc angled-lift splits is loosed core, die cavity is positioned at dynamic model part, is made up of two pieces of arc angled-lift splitses 5.Be product 10 in die cavity, product 10 side has the side direction in certain inclination angle to be shaped.

Fig. 1 is matched moulds die casting state.During matched moulds, the end face of arc angled-lift splits 5 contacts with the guide runner 12 in dynamic model frame 6, arc angled-lift splits 5 is entered in dynamic model frame 6 be reset to dynamic, cover half is completely closed.After cast molding, pressurize feeding, cooling and shaping, mould dynamic model part moves downward under the power of die casting machine, at this moment the dynamic model part of mould and arc angled-lift splits 5 drive product to depart from from fixed mold 1, between the two arc angled-lift splitses 5 that product is stayed in dynamic model, realize die sinking.

After die sinking, product wraps on dynamic mould core 11 and moves down with dynamic model part together with arc angled-lift splits 5, under the effect of push rod 9, arc angled-lift splits 5 relative upward movement is simultaneously to both sides somatotype, the action of somatotype is carried out movement in a curve to realize in the guide runner 12 of dynamic model frame 6 by arc angled-lift splits, the radian of guide runner 12 and the radian of arc angled-lift splits 5 match, and the center of arc of guide runner 12 center of arc and arc angled-lift splits 5 coincides.While arc angled-lift splits 5 undercut, product 10 is deviate from from dynamic mould core 11.Banking pin 13 is arranged to prevent from deviating from arc angled-lift splits 5 driven framed 6.This mould action is solid and reliable, guarantees, when push rod 9 releases arc angled-lift splits 5, to make angled-lift splits not easily produce unexpected inclination, is conducive to improving the mold use life-span.
