Examples
The present embodiment provides an internal parting injection molding bumper mold, as shown in fig. 1 to 4, comprising:
the first mold insert 1 is used for molding the inner surface of the edge of the headlamp of the bumper 7;
the second die core 2 is used for forming the inner surface of the upper edge corner 4 of the bumper 7; the edge of the second mold core 2 and the edge of the first mold core 1 are spliced along a straight line parallel to the inner surface of the corner 4, and the side surface of the second mold core 2 is provided with a lug 21 for forming a buckling hole 41 at the corner 4 of the upper edge of the bumper 7;
the third mold core 3 is used for molding the outer surface of the corner 4 of the upper edge of the bumper; the side surface of the third die core 3 can be attached to the end surface of the bump 21;
the second die core 2 can slide along a straight line parallel to the inner surface of the corner 4 under the driving of a driving mechanism, and meanwhile, the lug 21 is far away from the side surface of the third die core 3; after the second mold core 2 is moved out, the first mold core 1 can move towards one side of the second mold core 2 so that the first mold core 1 is separated from the inner surface of the edge of the bumper headlamp; the third die core 3 can be driven by the driving mechanism to be away from the outer surface of the corner 4 at the upper edge of the bumper.
As shown in fig. 3, for the bumper 7 to be formed in this embodiment, the curved surface structure of the inner surface of the bumper 7 is complex, and the space for movement of the mold core is small. Therefore, in the present embodiment, the first mold insert 1 and the second mold insert 2 are combined to perform parting, wherein the first mold insert 1 is used for molding the inner surface of the headlight edge of the bumper 7, and since the inner surface of the headlight edge has a structure with an inner hook as shown in fig. 3, the first mold insert 1 cannot be directly separated from the product when inverted, the second mold insert 2 needs to be separated from the corner 4 of the upper edge of the bumper 7 at first, that is, the second mold insert 2 is moved along a straight line parallel to the inner surface of the corner 4 in the first step of demolding, so that the second mold insert 2 does not extrude the product in the moving process, and the protrusion 21 is separated from the fastening hole 41; when the second die core 2 is separated from the corner 4, a larger moving space is left for the first die core 1, and then the first die core 1 can be separated from the edge of the headlamp of the bumper 7; and finally, the third die core 3 is driven by the driving mechanism to be away from the outer surface of the corner 4 at the upper edge of the bumper. Therefore, the parting mode of this embodiment can handle the parting of the bending part in the top of car bumper, can not cause destruction or extrusion to the product during the drawing of patterns, and the shaping outward appearance of product is better.
Preferably, the internal parting type injection bumper mold of the present embodiment, as shown in fig. 2, further comprises: a first slide rail 51 and a second slide rail 52; the first slide rail 51 is parallel to the inner surface of the corner 4, the second mold core 2 is provided with a first slide groove 22, and the first slide groove 22 can slide along the first slide rail 51; when the first sliding groove 22 slides along the first sliding rail 51, the bump 21 is far away from the side surface of the third mold core 3; the third mold core 3 is provided with a second sliding groove 32, and the second sliding groove 32 can move along the second sliding rail 52, so that the third mold core 3 is far away from the outer surface of the upper edge corner 4 of the bumper. Through the arrangement of the sliding rails and the sliding grooves, the direction of each mold core is accurate when the mold core moves, and friction between the mold core and the surface of a product when the mold core moves is avoided.
Preferably, in the internal parting injection molding bumper mold of the embodiment, the splicing surface of the first mold core 1 and the second mold core 2 is an arc surface with uniform curvature change. The longitudinal section of the arc is everywhere a straight line parallel to the inner surface of said corner 4.
Preferably, in the internal division type injection bumper mold of the present embodiment, as shown in fig. 1, the driving mechanism includes:
the driving rods 61 are connected with the first die core 1, the second die core 2 and the third die core 3;
and the driving parts are connected with all the driving rods 61 and can selectively drive one part of the driving rods 61 to move so as to enable the first mold core 1, the second mold core 2 and the third mold core 3 to move independently.
Preferably, as shown in fig. 4, in the internal parting injection bumper mold of the present embodiment, the first slide groove 22 and the second slide groove 32 are T-shaped grooves. Under the structure in T type groove, the spout removes along the slide rail and is difficult to take place to rock, and the removal process is more steady.
Preferably, in the internal parting type injection bumper mold of the present embodiment, the driving member is a motor or a cylinder.
In light of the foregoing description of the preferred embodiments according to the present application, it is to be understood that various changes and modifications may be made without departing from the spirit and scope of the invention. The technical scope of the present application is not limited to the contents of the specification, and must be determined according to the scope of the claims.
