Description

Aviation die design structure with negative angle for product molding surface Technical Field The utility model relates to the technical field of dies, in particular to an aviation die design structure with a negative angle aiming at a product molding surface. Background At present, the technology for demolding a complex aviation die generally completes the demolding process through the synergistic effect of components such as a lower die plate, an upper die plate, an oil cylinder, a push plate and a thimble, most of the molding surface of a product is in an irregular shape in the complex aviation die design process, sometimes the molding surface of the product can generate a negative angle, the product can not be smoothly removed in the demolding process and even adhered to the die, the technology generally needs complex technology and accurate matching, if the matching is poor, the plastic part is adhered in the die, particularly when the molding surface of the product has negative angle characteristics, the demolding is difficult, and in the production and manufacturing process, the problems not only affect the production efficiency and increase the cost, but also can cause adverse effects on the quality of the product. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides an aviation die design structure with a negative angle aiming at a product molding surface, and solves the problem of difficult die release caused by adhesion of the existing plastic part on a die. The aviation die design structure with the negative angle for the product molding surface comprises a first connecting plate and a second flange, wherein an insert is arranged on the first connecting plate, a connecting mechanism is arranged between the insert and the first connecting plate, and a pair of first bolt holes are arranged on the side wall of the insert; The second flange plate is provided with a split module, and the side wall of the split module is provided with a pair of second bolt holes. Preferably, the connecting mechanism comprises grooves formed in the lower wall surfaces of two sides of the insert, a pair of positioning and mounting blocks are mounted in the grooves, the positioning and mounting blocks are connected to the first connecting plate through bolts, and the insert is provided with an arc-shaped surface. Preferably, a pair of fixing blocks are respectively arranged on the lower wall surfaces of the two sides of the split module, the two pairs of fixing blocks are connected to the second flange plate, the split module is an arc-shaped block, and the radian of the arc-shaped block is the same as that of the arc-shaped surface. Preferably, the first connecting plate and the second flange plate are respectively provided with a plurality of connecting holes. Advantageous effects The utility model provides an aviation die design structure with a negative angle for a product molding surface, which has the following beneficial effects that the design structure designs a split type and insert type structure: The die forming surface is divided into a left part and a right part, one part is designed into an insert type structure, the other part is designed into a split type module, positioning and mounting are carried out by adopting a positioning block, and when the die is removed, the product can interfere with the die inner surface in the die removing process due to negative angle characteristics and the like of the product inner surface, at the moment, the positioning and mounting block on the insert is required to be separated from the flange plate in sequence, and then the bolt on the split type module is separated from the flange plate, so that the insert can slightly move through the reserved groove position, and the interference with the formed product is avoided, thereby the subsequent die removing work can be continued.
