Detailed ways

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and characteristics of the utility model can be more easily understood by those skilled in the art, so that the protection scope of the utility model can be defined more clearly .

Please refer to Fig. 1, the utility model embodiment comprises:

A thin turret mold for a bending machine that is easy to demould, comprising: an upper mold and a lower mold;

Described upper die comprises: adjusting nut 1, punch 2, demoulding spring 3, guide sleeve 4 and pressing plate 5, and the upper end of described punch 2 is provided with screw thread, realizes that described punch 2 and the described punch 2 are connected to each other through the screw thread. The connection of the adjusting nut 1 described above, the lower end of the punch 2 is provided with a punch, the guide sleeve 4 is placed on the lower end of the outer surface of the punch 2, and the pressure plate 5 is embedded in the guide sleeve 4 The bottom of the bottom, the demoulding spring 3 is placed on the end of the outer surface of the punch 2, and the demoulding spring 3 is located between the adjusting nut 1 and the guide sleeve 4;

The lower mold includes: a die 9, the bottom of the die 9 is provided with a hollow groove 11, and the upper surface of the die 9 is provided with a central hole 10, and the central hole 10 communicates with the hollow groove 11 .

Wherein, an elastic washer 7 is installed at the joint between the pressure plate 5 and the guide sleeve 4, so that the pressure plate can cause damage to the guide sleeve 4 when the pressure is too large.

A punch positioning block 8 is provided between the punch 2 and the guide sleeve 4 to perform positioning processing between the punch 2 and the guide sleeve 4 .

The diameter of the central hole 20 is not smaller than the diameter of the punch.

The outer surface of the release spring 3 is provided with a spring sleeve 6 , and the spring sleeve 6 is fixedly connected with the guide sleeve 4 .

Different from the prior art, the utility model discloses a thin turret mold for a bending machine that is easy to demould. Make the pressing depth of the punch 2 consistent with the processing size, and then fix the adjusting nut 1 on the stamping machine tool. When the stamping machine presses the product downward, the stripping spring 3 shrinks. At the same time, the punch 2 moves along the guide. The sleeve 4 presses and moves downward, and then the punch of the punch 2 performs stamping and bending processing on the product along the center hole 10 on the upper surface of the pressing plate 5 and the die 9. After the processing is completed, because the stripping spring 3 is in a contracted state, Therefore, after the stamping machine moves up, the upper mold will automatically pop up, so that the product will be lifted up together, so as to facilitate the ejection of the product.
