Hydraulic stop block mechanism of female mould of powder forming machine

Abstract

The invention provides a hydraulic stop block mechanism of a female mould of a powder forming machine. The hydraulic stop block mechanism comprises a cross arm and two ejecting rods matched with the cross arm, wherein two cross arm resetting air / oil cylinders are mounted on a frame; two regulating seats are fixed on the cross arm; regulating rods capable of synchronously moving up and down are connected with the inner parts of the regulating seats; a synchronous regulating transmission group is further connected to the two regulating rods; and the cross arm is matched with the oil cylinders mounted on the frame and can move up and down. Original irregular stop blocks and stop block parts which are difficult to process and easy to damage are replaced only by using the two oil cylinders mounted on the frame, parts need not to be processed, the maintenance and the replacement are simple and convenient, time and labor are saved, and the production cost is reduced. Meanwhile, the sizes of the oil cylinders are configured according to needs, so that the hydraulic stop block mechanism is suitable for being mounted and used on powder forming machines of different tonnages and different types and can be used for processing powder compacting parts in different shapes and of different thicknesses only by synchronously regulating the heights of the regulating rods on the cross arm left and right; and besides, the cross arm runs steadily and accurately, the generality is high, the practicality is high, the use effect is better, and the use is safer and more reliable.

Description

technical field [0001] The invention relates to an important part of a powder forming machine, which enables the continuous operation of the powder forming machine and the automatic block demoulding to ensure the processing quality of the pressed product. The powder forming machine female mold hydraulic stop mechanism. Background technique [0002] Chinese Patent No. 01245708.6 "Demolition Device for Powder Molding Machine" has a complex structure. The pressure wheel on the swing arm cooperates with the pressure block on the cross arm, and a boom with bearings, rollers, and roller shafts needs to be processed on the swing arm. , so its volume is large, and it is difficult to process many parts. It is only suitable for installation and use on small-tonnage powder forming machines.

Problems solved by technology

[0002] Chinese Patent No. 01245708.6 "Demolition Device for Powder Molding Machine" has a complex structure. The pressure wheel on the swing arm cooperates with the pressure block on the cross arm, and a boom with bearings, rollers, and roller shafts needs to be processed on the swing arm. , so its volume is large, and it is difficult to process many parts. It is only suitable for installation and use on small-tonnage powder forming machines.

[0003] Chinese Patent No. 200520131909.7 "Powder Molding Machine Female Mold Release Block Mechanism" replaces the original cross arm plus swing arm with an independent cross arm, cancels the swing arm and adopts the stop mechanism, but the cross arm still needs to be connected with the pressure rod , Ejection rod, and stopper mechanism, the stopper mechanism is an irregular part, it is difficult to process and install, and it is easy to wear after a long working time, and it is very troublesome to replace and maintain

[0004] Chinese Patent No. 200610053095.9 "Female Block Mechanism of Powder Forming Machine" uses a simple and easy-to-process inclined block to directly cooperate with the ejection rod, and drives the entire slider to move outward through the roller at the lower end, so that the pad on the bottom of the slider Break away from the contact with the stopper, so that the female template can move downward to complete the floating demoulding of the female mold. Although the structure has been improved, its structure is still relatively complicated, and there are many parts to be processed, and it is also difficult to process and install.
