Main die locking mechanism of blowing and embedding integrated machine

Abstract

The invention discloses a main die locking mechanism of a blowing and embedding integrated machine. The main die locking mechanism comprises a left die and a right die, the left die comprises a left main die, a left main die locking template and a left carriage, a jacking block assembly used for positioning the die locking position of the left main die is arranged between the left main die locking template and the left carriage, the jacking block assembly comprises a jacking block, the jacking block abuts between the left carriage and the left main die locking template when the main die locking template is in a locked state, and the jacking block disengages from the left carriage and the left main die locking template when the main die locking template is positioned in an open state. The main die locking mechanism of the blowing and embedding integrated machine has the advantages of improvement of the die locking reliability, improvement of the quality of finished bottle stopper products, and energy consumption reduction.

Description

technical field [0001] The invention relates to a blow-fill-seal integrated machine, in particular to a main mold clamping mechanism of a blow-fill-seal integrated machine. Background technique [0002] In the field of pharmaceutical machinery, the production process of the existing plastic ampoule blow-fill-seal integrated machine is mainly extrusion bottle making, filling and sealing, and residual material removal processes, that is, the ampoule bottle card made at the extrusion bottle making station is transferred to the filling process. After the station completes the filling and sealing, it is sent to the clamping mechanism to cut off the remaining material of the bottle card to obtain the finished product of the bottle card of the ampoule bottle. [0003] In the mold clamping mechanism, the left main mold first moves to the center plane of the mold clamping and is positioned, and then the right main mold reaches the center plane of the mold clamping and applies the req...

AI Technical Summary

Problems solved by technology

During the mold clamping process, the left and right main molds are closed by the servo electric cylinder and the articulated amplified booster lever to position the mold and generate the required mold clamping force. Since the booster connecting rod has multiple hinge points, it is inevitable that there will be Processing and assembly clearance errors, at the same time, wear between the shaft holes at the hinges during use may easily cause inaccurate positioning of the left main mold during long-term use of the equipment, that is, the left main mold cannot reach the accurate mold clamping center plane, As a result, the offset of the filling position will further affect the molding quality at the twisted fracture of the bottle clamp, and it will easily cause uneven thickness at the bottle mouth, which will prevent the user from twisting off the bottle clamp cap smoothly and normally during use.
