Injection molding machine insurance protection mechanism

Abstract

The invention belongs to the technical field of injection molding machine, and particularly discloses a safety protection mechanism of an injection molding machine. The safety and protection mechanismof the injection molding machine comprises a safety door, a bumper rod and a locking structure. A plurality of clamping grooves are formed in the upper surface of the bumper rod, and a plurality of clamping holes are formed in the lower surface of the bumper rod. The locking structure comprises a sliding rod which is slidably connected to a machine frame, and the sliding rod is fixedly connectedwith the safety door. A fixed block is fixedly arranged on a fixed wall of the injection molding machine, and a sliding hole is formed in the fixed block. A nut with a screw hole is rotatably connected to the fixed block, and a screw rod matched with the screw hole is arranged on the sliding rod. The nut is connected with a baffle block which can be clamped to a clamping groove. A first gear is arranged on the nut, and a second gear is rotatably connected to the lower portion of the fixed block. A limiting rod is slidably connected to the fixed block. A rack which meshes with the second gear is fixedly connected to the lower end of the limiting rod. When the staff opens the safety door for repair, the locking structure can be opened automatically, so that the movable wall and the fixed wall of the injection molding machine are restricted to perform spotting, and the injury to the staff is avoided.

Description

technical field [0001] The invention belongs to the technical field of injection molding machines, in particular to an injection molding machine insurance protection mechanism. Background technique [0002] The mold clamping system of the injection molding machine is mainly composed of a mold clamping device, a hinge, a fixed template, a movable template, a mold clamping cylinder and a safety protection mechanism to ensure that the mold is closed and opened. After the mold is closed, supply the mold with sufficient clamping force to resist the cavity pressure generated by the molten plastic entering the cavity, preventing the mold from opening and causing unqualified product quality. [0003] When the injection molding machine is working, it is constantly switching between opening and closing the mold. When the injection molding machine needs to be inspected and repaired, the safety protection mechanism controls the mold to be in the mold opening state. The safety protectio...

Problems solved by technology

However, relying solely on the electric control button to control the shutdown of the machine tool is not very reliable. In the event of damage to circuit components or errors in the program, the injection molding motor may be restarted, causing personal injury to the operator during maintenance.
