AI Technical Summary

Technical Problem

When replacing molds, the existing fully electric mold locking device using connecting rod structures needs to replace the connecting rod structure of the corresponding length to adjust the mold clamping distance, which is inconvenient to operate.

Method used

The eccentric shaft is used to adjust the mold clamp distance. The eccentric pin shaft passes through the front locking template and the mold locking arm, and the eccentric section of the eccentric shaft is matched with the front locking template. The eccentric pin shaft is rotated to change the position of the eccentric section of the eccentric shaft, thereby adjusting the horizontal distance between the front locking template and the mold locking arm to achieve the adjustment of the mold clamp distance.

Benefits of technology

Without changing the mold locking force, quickly loading molds of different thicknesses improves the versatility and convenience of the mold locking device and makes the mold replacement process more efficient.

Abstract

The utility model discloses a clamping device for adjusting the clamping distance through an eccentric shaft, comprising a clamping and clamping assembly, a front clamping plate, a rear clamping plate, a clamping arm, a swing frame seat and an eccentric pin shaft; one end of the clamping arm is connected to the clamping and clamping assembly, the eccentric pin shaft passes through the front clamping plate and the other end of the clamping arm, the shaft shoulder of the eccentric pin shaft cooperates with the clamping arm, the eccentric section of the eccentric pin shaft cooperates with the front clamping plate, and the shaft end of the eccentric shaft pin extends outside the front clamping plate. This connection method can not only realize the connection between the front clamping plate and the clamping arm, but also facilitate the adjustment of the clamping distance of the clamping device. Only by rotating the eccentric pin shaft to change the position of the eccentric section of the eccentric shaft, the horizontal distance between the front clamping plate and the clamping arm can be changed, thereby realizing the adjustment of the clamping distance, realizing the rapid loading of molds of different thicknesses without changing the clamping force, improving the versatility and convenience of the clamping device, and making the mold replacement process more efficient.
