Easy-to-demold lower ejection device for demolding and unloading of die forgings of screw press

Abstract

The invention discloses an easy-to-demold lower ejection device for demolding and unloading of die forgings of a screw press. The device comprises a main casing; a falling plate is mounted below the main casing; four connecting stand columns are evenly mounted on the upper end surface of the falling plate; a falling spring is arranged among the four connecting stand columns; two motors are evenlymounted inside the main casing; motor gears are fixedly mounted at the front ends of the motors; a transmission gear is mounted on one side of each motor gear; a threaded stand column is fixedly mounted in the middle of each transmission gear; a lifting sliding block is movably mounted on the outer side of each threaded stand column; and guiding sliding grooves are formed between the lifting sliding blocks and the main casing. According to the device, the falling plate, the falling spring, the connecting stand columns, connecting plates, lifting sliding blocks, lifting plates and the threadedstand columns are mounted, formed products can be ejected downwards from a mold after forging forming, product demolding is facilitated, and the device is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of screw presses, in particular to an easy-release lower ejecting device for demoulding and unloading die forgings of a screw press. Background technique [0002] With the rapid development of social economy, screw press refers to the general name of pressure machinery that generates pressure by rotating more than one set of outer bolts and inner bolts in the frame. Screw presses can be divided into two methods, one It is a method of applying torque to the bolt to generate static pressure. The other is the method of concentrating the rotational energy of the flywheel fixed on the bolt for forming. The screw press is mainly used for various high, medium and low-grade refractory materials. Formed product processing, or processing and forming of various metal material products (cold and hot forging processing, cold forging of thin forgings, casting and forging). [0003] However, the die forging equipment is u...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of easy demoulding bottom jacking device that is used for the unloading of screw press die forging, to solve the existing screw press proposed in the background technology that the product is inconvenient after the forging is formed. Detachment from the mold makes product collection inconvenient and reduces production efficiency, etc.
