Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 6, the mold for preventing a blank from being turned upside down provided by the present invention comprises a lower mold 1, wherein the lower mold 1 is provided with a forming groove 2 for placing the blank 6, at least one positioning column 3 is arranged at a non-central position of the forming groove 2, and the positioning column 3 is used for being inserted into the blank 6 to realize positioning; each positioning column 3 is connected with a driving mechanism 4 for driving the positioning column 3 to ascend and descend; specifically, the driving mechanism 4 is preferably an air cylinder, and the output end (e.g., a piston rod) of the driving mechanism 4 may be provided with a mounting plate 7, and one or more positioning posts 3 are mounted on the mounting plate 7.
The utility model discloses during the use, need the cooperation to go up the mould and use, the complex goes up the mould and is conventional structure, consequently no longer shows here and gives unnecessary details. And when using, the corresponding position of stock 6 is provided with locating hole 61, make before stock 6 puts into shaping groove 2, current actuating mechanism 4 drive reference column 3 stretches out shaping groove 2 suddenly, then put into shaping groove 2 to stock 6 again, make reference column 3 can assemble with locating hole 61 one-to-one, only under stock 6 does not put the prerequisite of turning over, reference column 3 just can insert in locating hole 61, stock 6 just can assemble into shaping groove 2 completely this moment, then descend and shrink into shaping groove 2 by actuating mechanism 4 drive reference column 3, just can carry out subsequent stamping forming action, because there is not the object in locating hole 61 this moment, consequently, the shape change of stock 6 can fill the punching press hole when the punching press, thereby avoided locating hole 61 to influence the outward appearance and the function of product.
In this embodiment, the molding groove 2 includes a plurality of molding portions 21, the molding portions 21 are detachably mounted on the lower mold 1, and the molding portions 21 sequentially abut against each other to form the molding groove 2. I.e. type groove 2 is the modularization setting, and the staff can change through the mode of changing the shaping portion 21 that corresponds position and shape according to the shape of the product of required production the utility model discloses the product that can produce to the required cost of mould development has been reduced.
