Abstract

The invention is suitable for the technical field of die-casting machines, and provides an auxiliary energy storage device. The auxiliary energy storage device comprises an energy storage component, an energy storage oil way, a power pump set, an oil tank and a controller, wherein the energy storage oil way is communicated with the energy storage component, and an oil outlet and an oil return portare arranged in the energy storage oil way and used for being communicated with a core pulling system of the die-casting machine; the power pump set is communicated with the energy storage oil way and used for providing a power source for the energy storage oil way; the oil tank is communicated with the power pump set and the oil return port; and the controller is connected to the energy storagecomponent, the power pump set and the energy storage oil way. According to the auxiliary energy storage device provided by the invention, the operation of a hydraulic circuit of a die-casting machinebody cannot be affected in the using process, the working process cannot conflict with the working procedure of the die-casting machine body, the production procedure is omitted, the production efficiency of a die-casting unit is improved; circulation between the oil ways does not exist between a hydraulic system of the device and a hydraulic system of the die-casting machine, and cross contamination is avoided.

Description

technical field [0001] The present application relates to the technical field of die casting machines, and more specifically, relates to an auxiliary energy storage device. Background technique [0002] At present, in the production process of complex die castings, cores are often used to realize cavities with complex structures. For molds with a core structure, core pulling operations are required during the die-casting process. [0003] For existing die-casting machines, the core-pulling system is often bound together with the die-casting machine body, sharing a set of hydraulic circuits. On the one hand, the core-pulling operation will generate partial pressure on the working oil pressure of the die-casting machine. This oil circuit design will make it difficult to carry out the core-pulling operation and the action of the die-casting machine at the same time; Often far away, the pressure drop and delay caused by the pipeline make the core-pulling action slow, and the c...
