Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a metal stamping die which is easy to demould. Background Art

[0002] When stamping hardware, a vertical stamping machine can be used to stamp the material into a product using a mold. The fixed mold fixed on the workbench of the vertical stamping machine is generally a convex mold, and an ejector device is often provided on the fixed mold. The movable mold is fixed on the pressing part of the vertical stamping machine, and there is a cavity on the movable mold. When the movable mold and the fixed mold are combined, the material can be formed into a product along with the mold cavity and the protruding part. When the stamping is completed, the product will be left on the fixed mold, and then ejected by the ejector device to separate the product from the fixed mold. However, the ejector device mostly ejects the product from the edge of the product or the inside of the product. The overall force of the product is uneven, which may cause damage to the product when it is ejected. In addition, due to design defects in the shape and shape of some products, it is inconvenient to evenly set the ejector device on the fixed mold, resulting in the product being partially stuck on the fixed mold, which is inconvenient.

[0023] Specifically, by installing the fixed die 100 on the workbench of the vertical stamping machine, the fixed die 100 is a convex die. Before the stamping machine performs stamping, the ring body 310 can be rotated so that the ring body 310 is moved to the side of the fixed die 100 without affecting the stamping of the stamping machine. When the stamping is completed, the product is located on the fixed die 100, and then the product is ejected by the ejection device on the fixed die 100. At this time, the ring body 310 can be rotated so that the ring body 310 covers the protruding part of the fixed die 100, and then the user passes the air inlet pipe 33 Gas is injected into the interior of the plurality of fixed cylinders 330 at the same time, so that the gas pushes the piston block 340 and the push rod 341 to move, so that the plurality of push rods 341 surround the product and synchronously push against various parts of the product to push against and clamp the product, and then the ring body 310 is rotated to make the plurality of push rods 341 cooperate with the ejection device on the fixed mold 100 to remove the product from the fixed mold 100, so that when the product is separated from the fixed mold 100, a separation force is simultaneously applied to the outside of the product, so that the force on the product is more uniform, and it is convenient for the product to be separated from the fixed mold 100.

[0024] Embodiment 1

[0026] In this embodiment, when in use, the rubber head 342 can be used to increase the friction between the push rod 341 and the surface of the product, so that after the multiple push rods 341 contact and clamp the product, the multiple push rods 341 can drive the product to separate from the fixed mold 100 by rotating the ring body 310. The air pump can be connected to the multiple air inlet pipes 331 through a multi-way connector, so that the air pump can inflate or exhaust air into the interior of multiple fixed cylinders 330 through the multiple air inlet pipes 331 at the same time, which is convenient for users to use.

[0027] like Figure 3 As shown, in this embodiment, a connecting plate 220 is fixedly connected to one side of the T-shaped base 200, and an electric push rod 230 is fixedly connected to the top surface of the connecting plate 220, the movable end of the electric push rod 230 is located above the support arm 320, the movable end of the electric push rod 230 is fixedly connected to a top block 231, and a pull rope 232 is fixedly connected between the center of one side of the top block 231 and the top surface of the support arm 320, and the top block 231 is a hemispherical structure.

[0028] During specific implementation, the electric push rod 230 can be started to drive the support arm 320 and the ring body 310 to rotate, so that the ring body 310 is sleeved on the protruding part of the fixed mold 100, and the support arm 320 is supported by the support plate 210 to prevent the support arm 320 and the ring body 310 from being skewed. The top block 231 is convenient for users to resist the rotation of the support arm 320. When the electric push rod 230 is reset, the pull rope 232 can be driven to pull the support arm 320 to rotate, so that the support arm 320 and the ring body 310 rotate synchronously, and the ring body 310 is separated from the fixed mold 100, which does not affect the stamping of the punching machine.

[0029] Embodiment 2

[0030] On the basis of the first embodiment, the efficiency of product demoulding is improved by providing an adsorption mechanism 400 .

A plurality of connecting holes are fixedly sleeved inside the plurality of connecting holes, and a rubber plug 440 is slidably sleeved inside the plurality of connecting cylinders 420, one end of the plurality of rubber plugs 440 is fixedly connected to a pressure rod 441, and one end of the plurality of pressure rods 441 is provided with a suction cup 443, and one end of the plurality of pressure rods 441 is connected to the top surface of the adjacent suction cup 443.

[0032] During specific implementation, the air pump is connected to the air guide tube 432, so that the air pump can synchronously inflate and exhaust air into the multiple connecting tubes 420 through the air guide tube 432 and the multiple connecting tubes 431. When the ring body 310 covers the protruding part of the fixed mold 100, the air pump is started to inflate the multiple connecting tubes 420. The rubber plugs 440 in the multiple connecting tubes 420 are pushed down by the gas, so that the multiple suction cups 443 are pressed down and adsorbed on the top of the product. The support rod 442 is made of rubber and has elasticity. When the pressure rod 441 presses the suction cup 443 on the top surface of the product, the suction cup 443 can be tightly attached to the top of the product due to the deformation of the adjacent support rod 442. When the ring body 310 is rotated, the multiple support rods 442 will synchronously pull the product to move through the suction cup 443, so as to facilitate the product to separate from the fixed mold 100.
