Abstract
The invention discloses an inner side core-pulling mechanism of a lever. The inner side core-pulling mechanism comprises a guide seat plate, a guide column, an inner inserting needle, power springs, a lever, a rotary shaft, resetting rods and a resetting striking plate, wherein the guide column is arranged on the guide seat plate at an interval in a penetrating manner; one end of the inner inserting needle is fixed on the guide seat plate and the other end of the guide seat plate stretches into a cavity; the guide column is sleeved with the power springs; the middle part of the lever is rotatably mounted on a rotary plate through the rotary shaft; the top face of the inner end of the lever butts against the guide seat plate; the top face of the outer end of the lever is ejected against the resetting striking plate; one end of the resetting rod is fixed on the resetting striking plate; the other end of the resetting rod stretches into a movable mould. Force is applied to the lever through the resetting rod and the swinging of the lever drives the inner inserting needle to enter the cavity; the elastic force of the power springs enables the inner inserting needle to be released from a product obtained by injection molding; the inner side core-pulling mechanism has the advantages of reliable movement and accuracy in insert positioning.
Description
Technical field
The present invention relates to a kind of injection mold, particularly relate to side core-pulling mechanism in a kind of lever.
Background technology
In mould for plastics, development is plastics injection mould faster.Its plastic product is also applied in daily life more and more widely, as each industrial circles such as building, machinery, electronics, instrument, instrument.In the time of plastic shaping, not only require to improve the quality of products, enhance productivity, but also require mould structure simple, reduce and be produced into wood.But complicated and with the product of interior inclined hole to plastic piece structure, some moulds go out the also more complicated of mould emptier of product at automatic trip, have a strong impact on service life and the maintenance of injection mold.
Summary of the invention
The object of the present invention is to provide the interior side core-pulling mechanism of lever of a kind of reliable in action, mold insert accurate positioning.
For achieving the above object, technical solution of the present invention is:
The present invention is side core-pulling mechanism in a kind of lever, and it comprises that guiding seat board, lead, interior pin, power spring, lever, swivel plate, rotating shaft, release link, reset re-pack; Described lead gap is located on guiding seat board, and one end of interior pin is fixed on guiding seat board, and the other end of interior pin stretches into die cavity, and power spring is socketed on lead and the two ends of power spring lean respectively on guiding seat board and dynamic model; Described lever middle part is by the rotatable swivel plate that is arranged on of rotating shaft, swivel plate is arranged in dynamic model, and the inner end face of lever leans with guiding seat board, and the outer end end face of lever and reset re-pack and lean, one end of release link is fixed on to reset and re-packs above, and the other end of release link stretches in dynamic model.
The present invention also comprises a wearing plate, and this wearing plate is arranged in dynamic model and is positioned at the below, outer end of lever.
The present invention also comprises a spacing bullet piece, and this spacing bullet piece is arranged in dynamic model and is positioned at the inner below of lever.
The inner end face of described lever is oblique crossing with outer end end face.
Adopt after such scheme, because the present invention is mainly re-packed etc. and to be formed by guiding seat board, lead, interior pin, power spring, lever, release link, reset, by release link to the lever application of force, utilize the interior pin of wobble drive of lever to enter die cavity, again, the elastic force of power spring makes interior pin depart from the product of injection mo(u)lding, has advantages of kind of a reliable in action, mold insert accurate positioning.
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
Brief description of the drawings
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention;
Fig. 3 is side view of the present invention;
Fig. 4 is application example of the present invention.
Detailed description of the invention
As shown in Figure 1-Figure 3, the present invention is side core-pulling mechanism in a kind of lever, it comprises guiding seat board 1, lead 2, interior pin 3, two power springs 4, lever 5, swivel plate 6, rotating shaft 7, two release links 8, reset re-pack 9, wearing plate 10, spacing bullet piece 20.
Described lead 2 has two, and two lead 2 gaps, interval are located on guiding seat board 1, and guiding guiding seat board 1 moves up and down stably along lead 2.One end of described interior pin 3 is fixed on guiding seat board 1, and the other end of interior pin 3 stretches into die cavity, and the quantity of interior pin 3 can be determined according to needs, is four in the present embodiment.Two described power springs 4 are socketed in respectively on lead 2 and the two ends of power spring 4 lean respectively at guiding seat board 1 and dynamic model 100(as shown in Figure 4) on.Described lever 5 middle parts are by the rotatable swivel plate 6 that is arranged on of rotating shaft 7, swivel plate 6 is arranged in dynamic model 100, the inner end face 51 of lever 5 leans with guiding seat board 1, the outer end end face 52 of lever 5 and reset re-pack and 9 lean, one end of two release links 8 respectively interval is fixed on to reset and re-packs on 9, and the other end of two release links 8 stretches into respectively in dynamic model 100 and can lean with cover half 200.Described wearing plate 10 is arranged in dynamic model 100 and is positioned at the below, outer end of lever 5, and described spacing bullet piece 20 is arranged in dynamic model 100 and is positioned at the inner below of lever 5.
The inner end face 51 of described lever 5 is oblique crossing with outer end end face 52, and or not a plane, its oblique crossing angle is determined according to the angle of product inclined hole.
As Figure 1 and Figure 4, operation principle of the present invention:
1, die sinking, dynamic model 100 separates with cover half 200, and the power spring 4 ejection guiding seat boards 1 that lean on guiding seat board 1 and dynamic model 100 move down along lead 2, drive the interior pin 3 being fixed on guiding seat board 1 to depart from product inclined hole.
2, mold closing, release link 8 upper ends are pressed on cover half 200 tops, make release link 8 by the reset 9 outer end end faces 52 of suppressing lever 5 that re-pack, lever 5 is swung around rotating shaft 7, the inner end face 51 of lever 5 upwards pushes up presses guiding seat board 1, the seat board 1 that makes to lead moves up along lead 2, drives the interior pin 3 being fixed on guiding seat board 1 to stretch into die cavity.
Emphasis of the present invention is just: adopt lever construction.
The above, it is only preferred embodiment of the present invention, the angle of inclination of lever end face can be determined according to needs, therefore can not limit scope of the invention process with this, the equivalence of doing according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
