In the preferred embodiment, the cylinder 413 is a thin cylinder including a cylinder 4131 and a piston rod 4132 that is expandable and contractible in the cylinder 4131. The top plate 414 is received in the sleeve 412 and is fixedly coupled to the piston rod 4132. The male mold base 42 has a rectangular plate shape and is fixed to the top end of the sleeve 412. A two-way hole 422 is defined in the middle of the male mold base 42 for the top rod 415 to be bored, and a plurality of guide posts 47 are fixed at the end. The backing plate 43, the splint 44, the backing plate 416, and the blanking plate 417 are all rectangular plate-shaped and are sequentially disposed above the male mold base 42. The mounting plate 43 is provided with two mounting holes 431 through which the jack 415 is inserted. A fixing hole (not shown) for accommodating the male mold core 45 is defined in the middle of the clamping plate 44. The clamping plate 44 further defines a mounting hole 442 for the ejector rod 415 to be disposed on both sides of the fixing hole. The pad 43 and the clamping plate 44 are both fixed to the male die holder 42 by a fixing member. A through hole 4161 through which the male mold core 45 is inserted is formed in the middle of the back plate 416. A through hole 4171 through which the male mold core 45 is inserted is formed in the middle of the blanking plate 417. The blanking plate 417 and the backing plate 416 are connected together by a fixing member. The two ejector pins 415 are fixed to the two ends of the top plate 414 and are fixedly connected to the back plate 416 after passing through the male die holder 42, the pad 43 and the clamping plate 44. The male mold core 45 is disposed in a fixing hole of the cleat 44, and is fixedly coupled to the male mold base 42 by a fixing member. The back plate 416 and the blanking plate 417 are sleeved on the male mold core 45, and are movable relative to the male mold core 45 by the oil cylinder 413. The master mold 50 includes a female mold base 51, a backing plate 52, a female template 53, 8 1322724, a female mold core 54 and a plurality of fixing members (not shown). The female mold base 51 has a rectangular plate shape, and a guide bushing 57 is fitted to a plurality of guide posts 47 on the male mold 40 at the ends thereof. The backing plate 52 and the female die plate 53 are sequentially disposed on one side of the female mold base 51, and are fixedly connected to the female mold base 51 by a fixing member. An opening (not shown) is formed in the center of the mother template 53. The female mold core 54 is received in the opening of the female die plate 53 and is fixedly coupled to the female mold base 51 by a fixing member. The female mold core 54 is provided with a groove 541 which cooperates with the male mold core 45, and the radial width of the concave groove 541 is larger than the radial width of the male mold core 45. Referring also to Figure 3, a processing machine 70 employing a mold 30 is shown. The processing machine 70 includes a base 71, a frame 72, and a die 30. A drive unit 721 and a guide rod 722 connected to the drive unit 721 are disposed on the top of the frame 72. The driving device 721 can be composed of an electric motor and a transmission mechanism, and can also be a pneumatic machine or a hydraulic press. The support plate 411 of the male mold 40 is fixed to the base 71, and the female mold base 51 of the female mold 50 is connected to the guide rod 722 and disposed opposite to the male mold 40. During processing, the top surface of the blanking plate 417 is adjusted to be flush with the top surface of the male mold core 45, and then the flat blank 80 is placed on the male mold core 45. The female mold 50 is driven vertically by the driving device 721. Moving downward, when the guide post 47 on the male mold 40 is inserted into the guide sleeve 57 on the female mold 50, the female mold 50 continues to move downward along the guide post 47. When the female die 53 of the female die 50 is in contact with the flat blank 80, the cylinder 413 is activated to apply an upward thrust to the piston rod 4132, and the thrust is transmitted to the blanking plate by the top plate 414, the top rod 415 and the back plate 416. 417, so that the blanking plate 417 and the female mold core 54 clamp the flat blank 80. Then, the master mold 50 is continuously pressed by the driving device 721, and pushes the pressing edge 9 1322724 plate 417 and the back plate 416 to move downward, so that the flat blank 80 is gradually pressed into the concave of the female mold core 50 by the male mold core 45. The groove 541 is until the workpiece is drawn to a predetermined shape. It can be understood that a plurality of male mold cores 45 can be disposed on the male mold 40 of the mold 30 of the present invention. The plurality of female mold cores 54 are correspondingly disposed on the female mold 50, and then the blanking plate 417 is respectively sleeved on the plurality of male mold cores 45, and The plurality of crimping plates 417 are respectively connected to the plurality of oil cylinders 413 in the male mold 40, so that the mold 30 can be processed by the multi-hole processing after being mounted on the processing machine 70. The male mold 40 of the mold 30 can also be mounted on the connecting rod 722 to fix the female mold 50 to the base 71. At this time, the processing machine 70 can also perform the drawing operation. Alternatively, the blanking plate 417 may be other crimping elements, such as a beading ring, and the beading plate 417 may be replaced by a plurality of crimping plates disposed around the male mold core 45. Two or more ejector pins 415 may be disposed on the top plate 413 to be connected to the blanking plates 417. Since the cylinder 413 is disposed in the mold 30, when the cylinder 413 fails, it is only necessary to take out the pressure cylinder 413 from the mold 30 for maintenance, and the operation is convenient. Moreover, the oil cylinder 413 can provide a constant blanking force to the blanking plate 417 during the drawing process of the flat blank, and clamp the portion of the flat blank 80 that is not drawn, so that the product made by the mold 30 can be made. Good quality. Further, the cylinder 413 is a thin cylinder having a small volume, so that the mold 30 is particularly suitable for drawing a small workpiece. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art of the present invention should be included in the following claims. 1322724 [Simple description of the drawings] Fig. 1 is a schematic diagram of a conventional deep drawing machine.
