AI Technical Summary

Technical Problem

The existing bottle blower mold locking mechanism has problems such as unreliable transmission accuracy, high installation accuracy requirements, noise caused by frame vibration and difficulty in locking the mold when moving at high speed.

Method used

A mold locking mechanism including mold frame support, positioning rod, left mold frame and right mold frame is designed. The mold frame is opened and closed through the swing arm shaft and the intermediate connecting rod mechanism, and the fixing hook and movable hook are used to use the structural design of the spring and the pressure gland to automatically compensate for the installation error and the gap caused by wear.

Benefits of technology

It improves the independence of the mounting hole position of the mold frame, reduces the shape and position tolerance requirements, simplifies the structure, facilitates installation and maintenance, and realizes stable mode locking during high-speed movement, reduces noise, and improves production efficiency and safety.

Abstract

The invention discloses a mold locking mechanism of a bottle blowing machine, which belongs to the field of plastic bottle production equipment, and comprises a mold frame support, a positioning rod is arranged on the mold frame support, a left mold frame and a right mold frame are movably arranged on the positioning rod, a swing arm shaft is arranged on the mold frame support, a mold locking swing arm is movably arranged on the swing arm shaft, and a mold locking mechanism is arranged on the mold locking swing arm. The mold locking swing arm is connected with the left mold frame and the right mold frame through a middle connecting rod mechanism; a left mold locking long shaft and a left mold locking short shaft are arranged at the front end of the left mold frame, and the left mold locking long shaft is arranged at the front end of the left mold frame in a penetrating manner; a plurality of groups of fixing hooks are mounted at the front end of the left mold locking long shaft; a right mold locking long shaft and a right mold locking short shaft are arranged on the right mold frame, the right mold locking long shaft penetrates through the front end of the right mold frame, and a plurality of sets of movable hooks are installed at the front end of the right mold locking long shaft. The requirement for form and location tolerance is lowered, and production and manufacturing are easier; the structure is simpler, installation and maintenance are convenient, and interchangeability is good; long-time stable operation is facilitated; and the working effect and efficiency are improved, noise is reduced during mold locking, and the surrounding working environment is guaranteed.
