Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] Such as Figure 1-5 As shown, the automotive composite interior trim of the present invention includes an aluminum plate 101 and a plastic part 102, both of which are tightly fitted and fixed together. During processing, the aluminum plate 101 is first put into the cavity of the mold and positioned, and then the mold is closed and fixed. injection molding.

[0028] The positioning mechanism of the injection mold for automotive composite interior parts of the present invention comprises the first A plate 1, the second A plate 2, the first fixed mold insert core 3, the second fixed mold insert core 4, the first movable mold insert core 5, the second movable mold insert core 6, the first B plate 7 and the second B plate 8; the first A plate 1 and the second A plate 2 are fixed, and the first fixed mold insert core 3 is fixed at the second The inner side of a plate A 1...

Abstract

The invention discloses a positioning mechanism for an injection mold of an automobile composite material interior decoration. In the first step of mold opening, the aluminum plate (101) of the interior decoration is put into the first fixed mold insert core (3) and the second fixed mold insert. core (4), while the two through holes of the aluminum plate (101) are respectively embedded on the step surface of the corresponding positioning column (9), the bottom surface of the aluminum plate (101) is inlaid with the first fixed mold core (3) and the second fixed mold The insert core (4) sticks to each other; in the second step of mold opening, start the cylinder (13), push the slider seat (12) and the slider (11), and the front end of the slider (11) extends into the cavity , the bottom surface of the slider (11) is offset against the top of the aluminum plate (101); this mechanism realizes integral injection molding with the aluminum plate, and the positioning structure can be better fitted during mold clamping and injection molding to avoid displacement of the aluminum plate.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a positioning mechanism for an injection mold of an automotive composite material interior decoration. Background technique [0002] At present, there is a kind of automotive composite interior trim, which is composed of aluminum plate and plastic parts. During processing, the formed aluminum plate is put into the mold first, and then the mold is closed for injection molding, so that the aluminum plate and the plastic are tightly fixed together. After the aluminum plate is directly put into the mold, it will inevitably not fit completely, or it will also cause displacement when the mold is closed, so that it cannot guarantee a sufficiently accurate position during injection molding. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an injection mold for automotive composite interior parts that can realize integ...
