Abstract

The invention provides a buffering braking mechanism of an electric injection molding machine. The mechanism comprises a servo motor, a fixing device, a connecting seat, a buffering braking device anda transmission mechanism, wherein the transmission mechanism comprises a first belt wheel, a second belt wheel and a transmission belt; the first belt wheel and the second belt wheel are connected through the transmission belt; the servo motor and the connecting seat are correspondingly fixed to the fixing device; the buffering braking device is fixed to the connecting seat through a screw; the servo motor is provided with an output shaft which penetrates through the fixing device, and the output shaft is connected to an inner circle of the buffering braking device through a flat key; the first belt wheel sleeves the output shaft; the second belt wheel is provided with a lead screw, and a nut is arranged on the lead screw; and the lead screw is connected to a moving part of the electric injection molding machine through the nut. According to the scheme, the mechanism has the advantages that the buffering braking device is arranged at one side of the output shaft of the servo motor, sothat the problem that a power mechanism of the electric injection molding machine is free from hydraulic buffering capacity can be solved; and the moving part of the electric injection molding machine is prevented from being damaged by the servo motor in case of out of control.

Description

technical field [0001] The invention relates to the technical field of electric injection molding machines, in particular to a buffer brake mechanism of an electric injection molding machine. Background technique [0002] The existing electric injection molding machine is different from the hydraulic injection molding machine. The injection power is output by the servo motor controlled by the driver, and the power mechanism of the low-friction servo motor does not have hydraulic buffer capacity. In some rare cases, the motor will completely There is no power output or the motor has no power output due to the emergency cut-off action after the power output of the motor cannot be controlled. When the electric injection molding machine is in the working state of injection action and pressure maintaining action, the motor loses power completely, which will damage or affect the performance of the electric injection molding machine. Moving parts, for example, when the motor is cut...
