Abstract
The utility mode discloses a double ejecting-rod slant-ejector structure for an injection mould, comprising an ejecting rod, a guide block, an auxiliary guide rod and a slant ejector. The double ejecting-rod slant-ejector structure is provided with the auxiliary guide rod, and the ejecting rod is in slip connection with the auxiliary guide rod. In the utility model, the auxiliary guide rod is arranged, so that the disengaging operation is reliable and stable, the design of the slant ejecting rod is not limited by 13 degrees, thus greatly decreasing the thickness of the mould with a disengaging distance structure.
Description
Technical field
The present invention relates to a kind of Double Tops bar ramp-roof structure, refer in particular to a kind of Double Tops bar ramp-roof structure that injection mold is produced that is used for.
Background technology
Injection mold generally includes cover half, dynamic model and ejecting mechanism, and the back-off structure on the product generally adopts the oblique top depanning, and oblique top mechanism generally comprises angle ejector rod, slider guide, ejector retainner plate and leading truck, and slider guide is fixed on the ejector retainner plate, and ejector retainner plate is positioned at leading truck.Single push rod oblique top is generally all adopted in the existing mold design, is subjected to the excessive stuck phenomenon that takes place of cross force active force for avoiding angle ejector rod, and the design gradient of push rod can not be done too greatly, generally is no more than 13 °.Dropout distance as product is bigger, can deviate from back-off for keeping oblique top to be no more than under 13 ° the situation, must strengthen mould tiltedly the side height and take off the stroke that part moves, cause mold thickness to increase greatly, need be installed on the injection machine of bigger specification and produce, cause production cost to rise.
Summary of the invention
The objective of the invention is to solve above-mentioned prior art problems, provide a kind of simple in structure, dependable performance stable, can effectively reduce mold thickness, reduce the Double Tops bar ramp-roof structure that large-angle inclined side wipes the burning chance.
The present invention is achieved in that
A kind of Double Tops bar ramp-roof structure that is used for injection mold comprises push rod, guide pad, secondary guide and tiltedly square, and described Double Tops bar ramp-roof structure is provided with secondary guide, and push rod slidably is connected with secondary guide.
Described secondary guide is connected by the hinged mode in two ends with push rod.
The angle α of described push rod and die sinking direction can be designed to 0～30 °.
Described guide pad is fixed on the dynamic model of injection mold, and tiltedly the side is fixed on the ejector retainner plate of injection mold ejecting mechanism, and the end of secondary guide is fixed on the injection mold ejecting mechanism.
The present invention is by being provided with secondary guide, and the cantilever cross force that makes push rod promoted by ejector retainner plate is directly delivered on the secondary guide of the hinged connection in two ends, and push rod only is subjected to the axial thrust effect, makes the dropout reliable in action stable, and the design of angle ejector rod no longer is subjected to 13.Restriction, reduced to have the mold thickness of big dropout distance structure greatly, tiltedly the stressed of side also improving simultaneously, significantly reduces the chance that large-angle inclined side wipes burning.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation that comprises injection mold of the present invention.
The specific embodiment
For being illustrated more clearly in technical scheme of the present invention, the present invention is further described below in conjunction with embodiment.
As shown in Figure 1 and Figure 2, a kind of Double Tops bar ramp-roof structure that is used for injection mold comprises push rod 1, guide pad 2, secondary guide 3 and oblique side 4, and described Double Tops bar ramp-roof structure is provided with secondary guide 3, and push rod 1 slidably is connected with secondary guide 3.
As Fig. 1, Fig. 2, shown in Figure 3, described secondary guide 3 is connected by the hinged mode in two ends with push rod 1.
As shown in Figure 3, described push rod 1 can be designed to 0～30 ° with the angle α of die sinking direction.
As shown in Figure 3, described guide pad 2 is fixed on the dynamic model 10 of injection mold, tiltedly side 4 is fixed on the ejector retainner plate 5 of injection mold ejecting mechanism, the end of secondary guide 3 is fixed on the injection mold ejecting mechanism, and the end of the secondary guide 3 of present embodiment is fixed on the base plate 6 of injection mold ejecting mechanism.
As Fig. 1, Fig. 2, shown in Figure 3, comprise that the mould of plastics operating principle of Double Tops bar ramp-roof structure of the present invention is as follows:
The cover half 7 of injection mold and dynamic model 10 matched moulds are also finished workpiece 8 die sinking after the injection mo(u)lding by back-off mold insert 9, cover half 7 is with after dynamic model 10 separates fully, ejector retainner plate 5 drive oblique side 4 promote push rods along 1 the direction of secondary guide 2 move axially, push rod 1 is being with back-off mold insert 9 to produce and is laterally being moved and breaking away from workpiece 8 back-offs simultaneously, the workpiece 8 of moulding breaks away from mould, finishes and takes off the part action.
The foregoing description is to further specify of the present invention, is not to concrete qualification of the present invention, therefore does the variation that is equal to according to the present patent application claim, is the scope that contains in the present invention.
