Abstract

The invention discloses a rubber sealing element forming die. The forming die comprises an upper pressing die, an elastic damper is fixedly connected to the side of the lower surface of the upper pressing die, a lower pressing block is fixedly connected to the middle of the lower surface of the upper pressing die, a supporting transverse plate is fixedly connected to the bottom end of the elastic damper, the bottom of the supporting transverse plate is fixedly connected with supporting legs, the upper surface of the supporting transverse plate is fixedly connected with a die wall, and the middle of the upper surface of the supporting transverse plate is sleeved with an anti-sticking device. The invention relates to the technical field of sealing element forming. According to the rubber sealing element forming die, rubber enters the forming die through injection molding, an upper pressing die can compress a plastic block through a lower pressing block to conduct forming of the rubber sealing element, operation is convenient, and construction of workers is facilitated; meanwhile, the height of the anti-sticking device and the height of a detection device are slightly higher than the upper surface of the supporting transverse plate, so that main power can be provided for the device when die pressing is performed through the die, and the energy-saving and environmental protection effects are achieved.

Description

technical field [0001] The invention relates to the technical field of seal molding, in particular to a rubber seal molding die. Background technique [0002] At present, a large number of rubber parts are used in equipment manufacturing and other industries, especially rubber seals used in gas-sealed, oil-sealed pistons, valves and other structures. Require. For rubber seals, the metal mold is directly placed in the mold base and used as a die. [0003] Existing molds for rubber seals often fail to discharge excess rubber injected into the mold, resulting in poor molding quality of the rubber after the rubber seal is formed later, and excess rubber will reduce the useful life of the mold. [0004] Moreover, in the rubber injection molding process, due to the viscosity of the rubber, it is difficult to discharge the air inside the mold, and when the air is discharged, it often leads to waste of rubber raw materials. Contents of the invention [0005] (1) Solved technica...
