Problems solved by technology

[0002] For a general press, the mold opening and closing cylinder has a long stroke and carries a heavy mold. Opening and closing the mold is a lifting and lowering action, and the gravitational potential energy will be converted into a large amount of heat energy and enter the return oil. , this part of energy is obviously a waste, and a large amount of cooling water or air must be consumed to maintain a suitable oil working temperature, which greatly increases production energy consumption and production costs

Abstract

The invention provides an energy storage regeneration energy-saving mold opening and closing system. The energy storage regeneration energy-saving mold opening and closing system comprises an energy supply hydraulic loop, a mold opening and closing hydraulic loop and an energy storage hydraulic loop. Through using energy storage and release effects of an energy accumulator, during mold closing, ahydraulic pump feeds oil to a rod cavity on a mold opening and closing oil cylinder, a main oil return way is closed, and under a combined effect of oil pressure of an upper rod cavity and gravity, oil in a lower rodless cavity enters into the energy accumulator and gravitational potential energy is converted into elastic potential energy; during mold opening, the hydraulic pump does not supply oil, the energy accumulator supplies oil to the lower rodless cavity so as to lift a cross beam, and the elastic potential energy is converted into the gravitational potential energy. A energy-saving effect is achieved through the energy accumulator. The energy accumulator is arranged on the energy storage hydraulic loop and can keep a proper distance from the mold opening and closing oil cylinder,a space problem is well solved, and safety means can be fully configured. By adopting the energy storage hydraulic loop, the elastic potential energy of the energy accumulator can be more convenientlyapplied to other hydraulic loops adopting low-pressure operation, and energy conservation and flexibility are considered.

Description

technical field [0001] The invention relates to the technical field of hydraulic control of vulcanizing machines, in particular to an energy storage regenerative and energy-saving mold opening and closing system and a mold opening and closing control method. Background technique [0002] For a general press, the mold opening and closing cylinder has a long stroke and carries a heavy mold. Opening and closing the mold is a lifting and lowering action, and the gravitational potential energy will be converted into a large amount of heat energy and enter the oil return. , this part of energy is obviously a waste, and a large amount of cooling water or air must be consumed to maintain a suitable oil working temperature, which greatly increases production energy consumption and production costs. Therefore, there is an urgent need for a mold opening and closing system that can stably convert and utilize gravitational potential energy. Contents of the invention [0003] In order ...
