Thin oil lubricating and injecting system without motor to drive in injection molding machine and thin oil lubricating and injecting device

Abstract

The invention provides a thin oil lubricating and injecting system without a motor to drive in an injection molding machine and a thin oil lubricating and injecting device used for the system. According to the thin oil lubricating and injecting system, a lubricant oil injecting pump is positioned in a lubricant oil storage tank; the lubricant oil injecting pump and an opening and closing mold oil cylinder are connected in parallel in an opening and closing mold hydraulic oil line of the injection molding machine; high pressure generated at the moment that the mold is opened by the injection molding machine is utilized to suck lubricant oil stored in the oil storage tank to the lubricant oil injecting pump; and then, high pressure at the moment that the mold is closed by the injection molding machine is utilized to discharge the lubricant oil in the lubricant oil injecting pump to an elbow mold closing mechanism of the injection molding machine, so that the elbow mold closing mechanism of the injection molding machine can be periodically lubricated when the mold is closed every time. According to the invention, no external motor is arranged in the thin oil lubricating and injecting system, the service life of oiling equipment is prolonged, and the energy conservation and consumption reduction are also realized at the same time.

Description

technical field [0001] The present invention relates to a lubricating and oiling system, in particular to a thin oil lubricating and oiling system for an injection molding machine driven by no external motor, and also relates to a thin oil lubricating and oiling device for the thin oil lubricating and oiling system of an injection molding machine, which belongs to the lubricating device technology field. Background technique [0002] Injection molding machine, also known as injection molding machine, is a molding equipment that uses plastic molding molds to make plastic products of various shapes from plastic raw materials. The injection molding machine heats the plastic, applies high pressure to the molten plastic, makes it shoot out to fill the mold cavity, and finally solidifies it into shape. The injection principle of the injection molding machine is similar to that of the syringe used for injection. It is the process of injecting viscous fluid plastic into the closed ...

AI Technical Summary

Problems solved by technology

However, in the prior art, the lubricating pump in the lubricating system is driven by an external motor. During the use of the injection molding machine, the motor needs to drive the lubricating pump to lubricate the toggle mold clamping mechanism, which increases additional energy consumption.

On the other hand, because of the low oil injection pressure of the traditional lubricating pump, it cannot fully lubricate the contact surface of the toggle, so the thin oil lubrication circulation system of the injection molding machine is not the most ideal lubrication system
