Detailed Description

The present utility model will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the present utility model, but are not intended to limit the utility model in any way. It should be noted that variations and modifications could be made by those skilled in the art without departing from the inventive concept. These are all within the scope of the present utility model.

In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Examples:

referring to fig. 1, the inside-molded bidirectional core pulling structure of the present utility model includes a lower pad 10, a lower clamping plate 20, a driving block 30, a floating plate 40 and two sliding punches 50, wherein the lower clamping plate 20 is disposed above the lower pad 10, two springs 60 are disposed between the lower clamping plate 20 and the floating plate 40, two second through holes 41 are disposed in the floating plate 40 along a horizontal direction, the sliding punches 50 are disposed in the two second through holes 41, the driving block 30 is fixed in the middle of the lower clamping plate 50, the driving block 30 includes an ejecting driving block 31 and a return driving block 32 fixed on the upper end of the ejecting driving block 31 by bolts 33, a driving portion 51 extends obliquely upward near one end of the sliding punch 50, a driving groove 34 matched with the driving portion 51 is disposed between the ejecting driving block 31 and the return driving block 32, the upper portion of the driving block 30 is disposed in a first through hole 42 disposed along a vertical direction and can move up and down in the first through hole 42, and the driving block 30 moves up and down in the second through holes 41.

Referring to fig. 1, the present utility model is matched with other known die structures, before die assembly, the floating plate 40 floats under the action of two springs 60, the driving portion 51 of the sliding punch 50 is located in the driving groove 34 of the driving block 30, at this time, the U-shaped product 70 is buckled on the floating plate 40, and the product 70 is positioned by profiling the shape of the floating plate. Referring to fig. 2, when the mold is closed, the floating plate 40 is pressed down and drives the sliding punch 50 to move downward, the driving portion 51 of the sliding punch 50 moves away from the driving block 30 under the blocking of the ejection driving block 31, so as to finish the inner molding of the product 70, and it is noted that the driving portion 51 does not separate from the driving slot 34. Referring to fig. 3, when the die is opened, the spring 60 pushes up the floating plate 40 and drives the sliding punch 50 to move upwards, and the driving portion 51 of the sliding punch 50 re-enters the driving slot 34, so that the product is easy to separate from the floating plate. Referring to fig. 4, after the mold is opened, the product is taken out from the floating plate 40, and thus the one-time stamping production process is completed. Through the structural design, the utility model is matched with other known die structures to finish the shape and inner side forming processing at one time, so that the processing procedures are reduced, two sets of dies of the shape forming processing and the inner side forming processing are not needed, and the die cost is reduced.
