Pressure-jetting real-time controlled differential oil path system in die casting machine

Abstract

The invention relates to die casting machines, injection molding machines, forging presses and the like, particularly belongs to the technical field of the die casting machines, and particularly discloses a pressure-jetting real-time controlled differential oil path system in a die casting machine. The pressure-jetting real-time controlled differential oil path system in the die casting machine isapplicable to a real-time controlled differential oil path, and comprises a pressure-jetting cylinder and pipelines for controlling oil to enter or be discharged out of the pressure-jetting cylinder,wherein the pipelines comprise the first pipeline connected to one side of the pressure-jetting cylinder for oil feeding, the third pipeline connected with the other side of the pressure-jetting cylinder for oil discharging, and the fourth pipeline arranged between the portion, with the third pipeline, of the pressure-jetting cylinder and the first pipeline and used for forming the differential oil path. The two sides of the pressure-jetting cylinder communicate in a one-way flowing mode, so that the pressure-jetting cylinder is prevented from generating high pressure or pressure impact in the working process, and the effect of enhancing stability is achieved.

Description

technical field [0001] The application relates to die-casting machines, injection molding machines, forging presses, etc., and is especially applicable to the technical field of die-casting machines. Specifically, it is a differential oil circuit system for injection real-time control in a die-casting machine, which is used in the differential oil circuit for real-time control. Background technique [0002] In the prior art: [0003] For example: Chinese patent: uniform acceleration injection system of die casting machine; a uniform acceleration injection system of die casting machine, mainly including injection cylinder, injection rod, injection punch, pressure chamber, mold and booster cylinder, energy storage devices, as well as oil pumps and valves, wherein the injection rod is pushed by the injection cylinder, the movement of the injection rod is divided into a slow injection stage, a fast injection stage and a pressurization stage, and the slow injection stage is divi...

AI Technical Summary

Problems solved by technology

[0006] This document is the closest prior art of this application. In this application, a complex oil circuit is used to design the pipeline, but there is still a situation where the local pressure of the pipeline in the oil circuit is relatively high

[0007] The above patent applications are all different because of their technical solution purposes and technical problems to be solved, so their technical solutions include differences in structure and method, and they cannot be simply combined for this patent application, otherwise it will lead to structural design. Complicated, or impossible to implement, etc.
