Problems solved by technology

[0002] In the field of manufacturing technology, double-material injection molds are relatively common molding molds, mainly used for double-material injection molding, that is, the injection molding of products with two-color materials. On the basis of the second injection molding, the second injection molding product combined with the semi-finished product is formed, and the semi-finished product and the second injection molding product are combined to form a complete product; however, there is a special structure for the semi-finished product, such as a through hole, a through groove, or a part of the semi-finished product. When the parts are suspended in the air, the secondary injection molded product must be combined with it to form an independent part, which is difficult to realize with the existing organic injection mold

Abstract

The invention provides a double injection mold which comprises a male mold, a male mold core located on the surface of the male mold, a first female mold and a first female mold core. The male mold core and the first female mold core form a basic part forming cavity; the injection mold further comprises an auxiliary assembly mounted on the male mold and the auxiliary assembly comprises a movable warp, a first leaning column penetrating through the male mold and an auxiliary ejector pin penetrating through the male mold core. Two opposite ends of the movable warp separately bear the first leaning column and the auxiliary ejector pin. When the first leaning column is pushed by the first female mold, the first leaning column is withdrawn to the male mold, so that the other end of the movablewarp pushes the tip of the auxiliary ejector pin to extend into the basic part forming cavity, so as to form a through hole of a basic part.
