Abstract
The utility model discloses a slant-ejecting and vertical-ejecting synchronous structure for an injection mould, comprising a slant ejecting rod, a vertical ejecting rod and an antiseize ejecting pin, wherein, the antiseize ejecting pin is fixed on the vertical ejecting rod. In the utility model, one vertical ejecting rod, which is moved simultaneously with the slant ejecting rod, is additionally arranged, and the antiseize ejecting pin is arranged on the vertical ejecting rod, thus effectively resolving the problem that the product will move horizontally with a back-off embedded piece during the demoulding process to affect the demoulding; the utility model can be used on the place in which a single slant ejector mechanism can not be provided with the antiseize ejecting pin and produces adhesive products because of small structure size; and the utility model is capable of improving the moulding qualification rate of the products.
Description
Technical field
The present invention relates to a kind of oblique top, straight top synchronization structure, refer in particular to a kind of oblique top, straight top synchronization structure that injection mold is produced that be used for.
Background technology
Take off in the back-off structure in the oblique top of mould of plastics, marquis's article construction causes goods to have an opportunity to be bonded at following the back-off mold insert on the back-off mold insert moving together sometimes, influences effective demoulding of goods.Be head it off, existing mold usually increases antiseized thimble on the back-off mold insert, as shown in Figure 1, drive angle ejector rod 1-4 at ejector retainner plate 1-6 and laterally move together with back-off mold insert 1-3 in the disengaging dynamic model 1-7 back-off process, withstand goods 1-1 by the antiseized thimble 1-2 among the back-off mold insert 1-3 and prevent that goods 1-1 is along with back-off mold insert 1-3 moves together.This thimble structure is complicated, and requires thimble plane of orientation distance H enough just can use greatly the time, for the not enough occasion in space, can't use this mechanism.
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 oblique top of injection mold, straight top synchronization structure of being used for comprises angle ejector rod, straight push rod and antiseized thimble, and described antiseized thimble is fixed on the straight push rod.
As preferably, described antiseized thimble is vertically fixed on the straight push rod.
The present invention is by increasing by one and the synchronization-moving straight push rod of angle ejector rod, and antiseized thimble is contained on the straight push rod, efficiently solve in the knockout course goods and follow the problem that the back-off mold insert produces the horizontal moving influence demoulding, can push up mechanism can't adorn the adhesion of antiseized thimble product because of physical dimension is little occasion use in monocline, can improve the depanning qualification rate of goods effectively.
Description of drawings
Fig. 1 takes off the structural representation of back-off structure for the oblique top of existing injection mold.
Fig. 2 is a perspective view of the present invention.
Fig. 3 is a structural representation of the present invention.
Fig. 4 is that the A of Fig. 3 is to cutaway view.
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 Fig. 2, Fig. 3, shown in Figure 4, a kind of oblique top of injection mold, straight top synchronization structure of being used for comprises angle ejector rod 4, straight push rod 5 and antiseized thimble 2, and described antiseized thimble 2 is fixed on the straight push rod 5, and the antiseized thimble 2 of present embodiment is vertically fixed on the straight push rod 5.
As Fig. 2, Fig. 3, shown in Figure 4, when the oblique top of injection mold of the present invention, the synchronization structure work of straight top, straight push rod 5 vertically ejects motion, drive antiseized thimble 2 and move both vertically and withstand workpiece 1 always, simultaneously, angle ejector rod 4 promote back-off mold inserts 3 along with vertical direction oblique moving at an angle, back-off mold insert 3 produces the relative motion that breaks away from back-off, because antiseized thimble 2 supporting workpieces 1 back-off is arranged, make back-off mold insert 3 can break away from workpiece 1 back-off smoothly, realize the no adhesion demoulding.
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.
Claims (2)
