Oil press with functions of buffering, noise reduction and convenient mold mounting and dismounting

Abstract

The invention discloses an oil press with functions of buffering, noise reduction and convenient mold mounting and dismounting. The oil press comprises a hydraulic control structure, a base, a workbench arranged on the base, an upper cross beam, a guide column connected between the workbench and the upper cross beam and a middle beam which is connected to the upper cross beam through an oil cylinder and connected with the guide column. The workbench is of a split structure and comprises a fixing part connected to the base and the guide column, and a sliding block connected to the fixing part.The base is further provided with a driving structure which is connected with the sliding block and used for driving the sliding block to reciprocate front and back on the fixing part in the linear direction. The guide column is sleeved with a rubber buffer sleeve. One end of the rubber buffer sleeve is connected to the workbench, and the other end of the rubber buffer sleeve is connected to the middle beam. A mold can be mounted and dismounted conveniently, in addition, the guide column can be prevented from being damaged, the reliability is better, and the noise is low.

Description

technical field [0001] The invention relates to the technical field of hydraulic presses, in particular to a hydraulic press with the functions of buffering, noise reduction and convenient mould-mounting and dismounting. Background technique [0002] The hydraulic press is a kind of special hydraulic oil as the working medium and the hydraulic pump of the hydraulic station as the power source. Under the force of the pump, the hydraulic oil enters the hydraulic cylinder through the hydraulic pipeline, pressure control valve, flow control valve, and directional control valve. Transform hydraulic energy into mechanical energy; through the mechanical, electrical, and hydraulic control systems, the hydraulic oil circulates in the hydraulic system to make the piston reciprocate and linearly move again and again, so as to meet the technological requirements of the product; the hydraulic press can be classified according to the structural form: Four-column hydraulic press, single-colu...

AI Technical Summary

Problems solved by technology

[0003] 1. The guide pillars are set on the four corners of the workbench. When loading and unloading the mold on the workbench, there is a high probability that the guide pillars will be touched, which will not only easily damage the guide pillars, but also affect the guidance of the middle beam, seriously It will affect the molding quality of the product;

[0004] 2. There is no protective structure on the guide post, which is not only easy to be damaged, but also has no buffering and noise reduction function, so the reliability is not high
