Description
Technical Field
The invention relates to the technical field of mold manufacturing, in particular to an internal double-elastic-needle back-off mechanism of an automobile bumper injection mold.
Background
Injection molding is a method for producing and molding industrial products. The products are generally produced by rubber injection molding and plastic injection molding. The injection molding method has the advantages of high production speed, high efficiency, automation of operation, various colors, various shapes from simple to complex, small sizes, accurate product size, easy replacement of products, capability of forming products with complex shapes, and suitability for the molding processing fields of mass production, products with complex shapes and the like.
In the injection molding of plastic products, some plastic product structures are usually provided with a ring-shaped inverted buckle or an inward recess, and the plastic products cannot be taken out of a mold core through a conventional ejection mechanism after being molded. Special designs are required to address this problem. However, due to the assembly requirement, a plurality of mounting holes are usually made to be very close, and a step is arranged nearby, so that the inclined top or the sliding block cannot be interfered with enough running space, and therefore, the inclined top or the sliding block cannot be ejected by directly designing according to the traditional design.
For example, chinese patent document (publication No. CN 203876172U) discloses a "undercut-removing assembly and a mold comprising the same", the mold comprising the undercut-removing assembly, the undercut-removing assembly comprises a straight top and an inclined top block, the inclined top block is arranged in an inclined channel on the straight top in a penetrating manner, the inclined top block is provided with a hook head portion hooked with an undercut of a model product and a guide block which penetrates through an outer wall of the straight top and is limited by a mold core, the guide block is fixedly arranged on at least one side of the inclined top block, the outer wall of the straight top is provided with a limiting groove for accommodating and limiting the guide block, and when a limiting effect of the mold core on the guide block in an axial direction of the limiting groove disappears, the guide block slides along the limiting groove.
Above-mentioned technical scheme provides the space of stepping down to the slider that leads that has broken away from the mold core spacing through the spacing groove to the realization takes off the back-off effect, but the back-off effect that takes off of this kind of scheme receives the size restriction of spacing groove, and when the mould size is less, straight top and oblique kicking block interval are very narrow, and the operating space is not enough, consequently can't accomplish the top action to one side.
