Description
Technical Field
The invention relates to a mold, in particular to a direct jacking glue structure and an injection mold.
Background
The middle-large injection mold needs to use a hot runner system for auxiliary glue feeding, for an inverted mold, the conventional glue feeding design is to directly connect glue feeding points of a hot runner with the structure of a product, and no auxiliary runner is overlapped in the middle. When the space of the product structure is not enough to reasonably place all hot runner glue inlet points directly connected with the product, the auxiliary flow channel is used for overlapping to complete the connection between the hot runner glue inlet points and the product, and the requirement of injection molding and filling is ensured.
The overlapping runner of the conventional flip-chip mold is generally designed into a section of inverted cone structure, as shown in fig. 1, which is beneficial to removal after treatment and does not generate excessive runner material waste. However, when the structural space on the back of the product is limited, in order to ensure that the product does not have the defects of material shortage, gas trapping and the like in injection molding filling, two or three points are required to be injected and filled together in different places of one region through moldflow mold flow analysis, and then the single-point inverted cone lap joint runner cannot meet the requirements. As shown in fig. 2, the front grid main body part has a grid-shaped product structure, and the optimal injection molding filling scheme in the illustrated circle region is realized by simultaneously feeding glue from three points, while the size of the product itself cannot be simultaneously provided with three hot runner glue feeding point structures, and only one hot runner glue feeding point is adopted and matched with a lap joint flow channel for feeding glue from three points. As shown in fig. 3, since a cylindrical glue inlet channel structure (a circular area shown in the figure) is left in the overlapping flow channel and is connected with a glue inlet point of the hot runner, it is difficult to realize that the overlapping flow channel can be smoothly ejected and demoulded along with the product without breaking during ejection.
