Quick die changing device for forming machine

Abstract

The invention discloses a quick die changing device for a forming machine, which comprises a die, a pair of bolt grooves, a pair of clamping blocks, a pair of clamping blocks and a pair of clamping blocks, the outer sides of the fixing pieces are respectively connected with a locking piece, each locking piece extends towards the corresponding bolt groove to form a lock bolt, and the top surface of each locking piece is additionally provided with an unlocking groove; the unlocking mechanism is arranged on the top surface of the lifting seat and comprises at least one first telescopic driving device and a pair of unlocking blades which are synchronously driven by the first telescopic driving device and correspond to the pair of unlocking grooves in position; when the pair of unlocking blades are inserted into the pair of unlocking grooves, the pair of locking pieces form transverse displacement on the outer sides of the pair of fixing pieces under the elastic action of the elastic displacement mechanism, so that the lock bolts are separated from the corresponding bolt grooves, and the bottle opening mold is unlocked.

Description

technical field [0001] The invention relates to a quick mold changing device, in particular to a quick mold changing device for a molding machine, such as an injection molding machine or an injection blow molding machine. Background technique [0002] Molding machines, such as injection molding machines or injection blow molding machines, are indispensable equipment for making plastic products. The above-mentioned molding machine produces plastic products through moulds, so different moulds must be replaced to produce plastic products of different styles. [0003] That is to say, taking the bottle mouth mold of the existing injection blow molding machine as an example, the injection blow molding machine includes a workbench and a turntable located on the bottom surface of a lift seat, and the workbench and the lift stand are provided with at least three Stations, such as an injection station, a bottle blowing station, and an ejection station. And the bottom surface of the ...

Problems solved by technology

[0006] It can be seen from the above-mentioned mold changing operation that the pair of fixing parts at each station needs to be disassembled and locked before a new bottle mouth mold can be replaced, and at least two operators are required for the mold changing operation, which is in vain. The waste of manpower and the consumption of time can be called a fly in the ointment.
