Anti-pinch device for vertical parting flaskless shoot squeeze molding machine

Abstract

The invention discloses an anti-pinch device for a vertical parting flaskless shoot squeeze molding machine. The anti-pinch device comprises a rack, a mounting hole, a first rotating shaft, a gear, a second rotating shaft, a bevel gear set, an overrun clutch and a third rotating shaft, wherein the rack is arranged at the bottom of the side face of a hydraulic mold pushing machine; the mounting hole is formed in the ground between the hydraulic mold pushing machine and a sand mold, and the first rotating shaft is rotatably and vertically arranged on one side, close to the hydraulic mold pushing machine, of the mounting hole; the gear is fixedly arranged at the top end of the first rotating shaft and is meshed with the rack, and the second rotating shaft is rotatably and horizontally arranged in the mounting hole; two bevel gears of the bevel gear set are arranged at the outer side end of the second rotating shaft and the middle portion of the first rotating shaft respectively, and the two bevel gears are meshed with each other; and the overrun clutch is arranged at the inner side end of the second rotating shaft, and the third rotating shaft is rotatably and horizontally arranged in the mounting hole and located on the axis extension line of the second rotating shaft. The anti-pinch device for the vertical parting flaskless shoot squeeze molding machine is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of sand shakeout machines, in particular to an anti-clip device for a vertical split boxless injection molding machine. Background technique [0002] The vertical split boxless injection molding machine is a relatively advanced casting molding machine, which is adopted by many foundry manufacturers because of its advantages of high productivity, accurate casting size, saving sand and high degree of automation. When the hydraulic mold pushing machine of the molding machine pushes the sand mold made by the sand mold making machine onto the sand mold transmission channel, the hydraulic mold pushing machine repeatedly performs jacking and retracting work, and when the hydraulic mold pushing machine retracts the sand mold making machine At this time, it is necessary for the mold maker to clean up and add materials between the hydraulic mold pusher and the sand mold that has been made. Since the hydraulic pressure...

Problems solved by technology

However, after a long period of research, it was found that although this prior art can push the staff to withdraw from between the hydraulic mold pusher and the sand mold, its structure limits the movement of the staff, which makes it inconvenient for the staff to work and move. problem, and the structure set on the hydraulic mold pusher and sand mold affects the operating space in the factory, which is not conducive to the movement of staff
