Abstract

The embodiment of the invention discloses a control circuit of an injection molding machine. The control circuit comprises a control panel, a starting switch and an emergency stop switch, wherein the control panel is electrically connected with a keyboard plate on an injection molding machine housing and used for outputting corresponding switching control signals according to control parameters input by a user to realize running control of the injection molding machine; the starting switch is connected with a motor starting signal in the switching control signals and used for controlling a motor to be started; and the emergency stop switch is connected with a motor emergency stop signal in the switching control signal and used for controlling the motor to be stopped emergently. According to the control circuit of the injection molding machine, provided by the embodiment of the invention, a traditional control circuit of the injection molding machine can be replaced to greatly lower the machine debugging difficulty.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of injection molding machines, and in particular to a control circuit of an injection molding machine. Background technique [0002] The plastic product processing industry is one of the industries with the fastest development speed in the light industry in recent years. In 2002, the industry's total industrial output value was 240.848 billion yuan, ranking third among the 22 major industries in the light industry. [0003] Injection molding machines are the most commonly used equipment in the plastic product processing industry. Through the injection molding and forming of plastics on the injection molding machine, the raw materials can be processed into various products with different functions. In the daily use of injection molding machines, inspection and maintenance are very important. However, in the repair and maintenance of various old-fashioned injection molding machines, it ...
