Abstract

The present invention discloses a mechanical mold for a punching machine, the structure of which comprises an upper mold plate, a punching port, a punching column, a column, a mold jam prevention device, a base, a buffer lower cylinder, an upper cylinder, a material clearing port, and a mold box. The mold jam prevention device comprises a shell, a protective cylinder, a support plate, a gear, a pressure plate, a displacement plate, a prevention rod, a hydraulic cylinder, a side oil groove, a sealing plate, a push rod, a sliding rod, and an oil connecting cylinder. The mold jam prevention device is structurally arranged, and a small protrusion at the bottom of the upper mold plate corresponds to a groove type above the support plate. When the punching reaches the bottom end, the support plate on the right side of the support plate moves downward under the action of a force, and the displacement plate pushes another hydraulic rod on the oil connecting cylinder to articulate the sliding rod, so that the push rod moves a certain distance to the right. The oil filled in the side oil groove is pushed into the hydraulic cylinder by the sealing plate, and the prevention rod moves a short distance upward, so as to prevent the upper mold from being stuck at the bottom and being difficult to reset when the buffer cylinder is damaged in the punching state.

[0020] The gear 504 mentioned in this patent refers to a mechanical element with continuous meshing on the wheel rim to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of the gear cutting method and the special machine tools and tools for gear cutting based on this principle appeared one after another. With the development of production, the stability of gear operation has been paid attention to; the hydraulic cylinder 508 is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion or swinging motion. It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the reduction device can be eliminated, and there is no transmission gap and the motion is stable.

[0021] For example, when Mr. Lin was using a mechanical mold for a punching machine, when punching the mold, the upper mold plate 1 applied force downward, and the casting mold material in the mold box 10 was molded under the action of the punching force. During the displacement of the upper mold plate 1, the small protrusion at the bottom of the upper mold plate 1 corresponded to the groove type above the support plate 503. When the punching reached the bottom, the support plate 503 on the right side of the support plate 503 was moved downward by the force, and the displacement plate 506 pushed another hydraulic rod hinged slide bar 512 on the connecting cylinder 513, so that the push rod 511 moved a distance to the right, and the oil filled in the side oil groove 509 was pushed into the hydraulic cylinder 508 by the sealing plate 510, and the prevention rod 507 moved upward a short distance, which could prevent the upper mold from being stuck at the bottom and difficult to reset when the buffer cylinder was damaged under the punching state.

[0022] The present invention solves the problem that the buffer cylinder of a mechanical mold is easily damaged under long-term stamping conditions, and it is difficult to effectively prevent the upper mold from being stuck at the bottom and difficult to reset. The present invention structurally arranges a mold jam prevention device through the combination of the above-mentioned components. The small protrusion at the bottom of the upper mold plate corresponds to the groove type above the support plate. When the stamping reaches the bottom, the support plate on the right side of the support plate moves downward under the action of force, and the displacement plate pushes another hydraulic rod hinged sliding rod on the connecting cylinder to move the push rod to the right for a distance. The oil filled in the side oil tank is pushed into the hydraulic cylinder by the sealing plate, and the prevention rod moves a short distance upward, which can prevent the upper mold from being stuck at the bottom and difficult to reset when the buffer cylinder is damaged under the stamping condition.
