AI Technical Summary

Technical Problem

In the plastic welding of interior and exterior decorations of automobiles, the traditional upper mold and lower mold reciprocating mechanism uses spur gears and racks to drive, resulting in poor transmission accuracy, and the upper mold frame or lower mold frame may have one end higher and the other end higher during the lifting process of the upper mold frame or lower mold frame. The problem of shortness cannot maintain horizontal lifting.

Method used

Adopt a structure including an upper mold frame, a lower mold frame, a linear guide rail, a helical gear, a helical rack and a driving device. The spindle is driven by a reduction motor and is fixedly connected to the spindle and a sub-shaft using an adjustment flange assembly, combining the helical gear and a bevel The transmission of the rack ensures horizontal lifting and lowering of the upper mold frame and improves stability and accuracy through components such as fall protection devices and bearing seats.

Benefits of technology

Improve the transmission accuracy and stability of the upper and lower mold frames, ensure that they are always level during the lifting process, extend the service life, and avoid falling risks through fall prevention devices.

Abstract

The utility model discloses an upper and lower mould frame reciprocating motion mechanism which comprises an upper mould frame, a lower mould frame, linear guide rails, helical gears, helical racks and driving devices, the two ends of the upper mould frame and the two ends of the lower mould frame are respectively connected with the corresponding linear guide rails in an ascending and descending sliding mode, and the driving devices are arranged on the upper mould frame and the lower mould frame. The driving device comprises a gear motor, a main shaft, an auxiliary shaft and an adjusting flange assembly, the gear motor drives the main shaft to rotate, one end of the auxiliary shaft is fixedly connected with one end of the main shaft through the adjusting flange assembly, bevel gears are fixed to the other end of the main shaft and the other end of the auxiliary shaft, and the bevel gears are meshed with the corresponding helical racks. The upper mold frame and the lower mold frame can be adjusted, and it is guaranteed that the upper mold frame and the lower mold frame can both ascend and descend horizontally.
