Abstract

The utility model provides a die casting machine energy-saving control system which can reduce energy consumption of a die casting machine. The die casting machine energy-saving control system comprises an electricity-saving control cabinet capable of collecting pressure and flow of the die casting machine, wherein the electricity-saving control cabinet is connected with a motor, the motor drives an oil pump, an oil outlet of the oil pump is provided with a pressure sensor, and the pressure sensor is connected with the electricity-saving control cabinet. According to the die casting machine energy-saving control system, detection and feedback for the pressure and the flow of the system are achieved at every moment, rotation speed and torque of the synchronous motor are timely changed by means of an energy-saving controller, corresponding adjustment for the pressure and the flow are achieved, and actually given pressure and flow are fast, accurately and stably achieved through maintenance of the pressure of the system; and the relief flow rate of the die casting machine is controlled to be minimum, production requirements of the die casting machine are met, meanwhile the purpose of saving energy is achieved, and on-demand supply is achieved.

Description

A kind of die casting machine energy-saving control system

Technical field

The utility model relates to a kind of die casting machine equipment, especially a kind of die casting machine energy-saving control system.

Background technology

At the die casting production industry; The course of work of die casting machine has comprised processes such as matched moulds, high-voltage lock mould, a rapid fire material, two-speed shoot material, pressurize, cooling, die sinking, clear material, and required pressure fuel pump of each stage is different with flow, and promptly each is different to the coupling of pressure, flow each stage; And the power of Oil pump electrical machinery is to be equipped with according to peak load in its running; But die casting machine has only high-voltage lock mould bigger with the stage load that shoots material in production cycle; Other working stage hydraulic pressure workload demand is less, and special its load of cooling procedure is almost nil; Concerning the oil pump hydraulic system, if oil pump still turns round with the full load revolution, its fuel delivery is invariable, and unnecessary hydraulic oil flows back to fuel tank through overflow valve, flogs a dead horse, and has wasted electric energy.The electric energy loss of Oil pump electrical machinery is serious in the entire work process of die casting machine, and utilization rate of electrical has only 30%～50%.

The utility model content

The utility model provides a kind of die casting machine energy-saving control system that reduces the die casting machine energy consumption.

Realize the die casting machine energy-saving control system of the utility model purpose; Comprise the economize on electricity switch board that can gather die casting machine pressure and flow, said economize on electricity switch board links to each other with motor, the motor-driven oil pump; The oil-out place of oil pump is provided with pressure sensor, and said pressure sensor links to each other with the economize on electricity switch board.

The beneficial effect of the die casting machine energy-saving control system of the utility model is following:

The die casting machine energy-saving control system of the utility model; Pressure and flow to system detects feedback constantly; In time change the rotating speed and the torque of synchronous motor through energy-saving controller; Pressure, flow are made corresponding adjustment, finally keep the fast, accurate and stable pressure and the flow that reaches setting of pressure of system; The spillway discharge of die casting machine is controlled at minimum, had both satisfied the production needs of die casting machine, reached energy-conservation purpose again, what needing having realized, what are just supplied with.

Description of drawings

Fig. 1 is the structural representation of the die casting machine energy-saving control system of the utility model.

The specific embodiment

As shown in Figure 1; The die casting machine energy-saving control system of the utility model; Comprise the economize on electricity switch board that can gather die casting machine pressure and flow, said economize on electricity switch board links to each other with motor, the motor-driven oil pump; The oil-out place of oil pump is provided with pressure sensor, and said pressure sensor links to each other with the economize on electricity switch board.

The advantage of the die casting machine energy-saving control system of the utility model is following:

Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.

Claims

1. die casting machine energy-saving control system; It is characterized in that: comprise the economize on electricity switch board that can gather die casting machine pressure and flow, said economize on electricity switch board links to each other with motor, the motor-driven oil pump; The oil-out place of oil pump is provided with pressure sensor, and said pressure sensor links to each other with the economize on electricity switch board.
