Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of extrusion casting machines, in particular to a lubricating oil circuit of a horizontal extrusion casting machine. Background Art
[0002] Existing horizontal extrusion casting machines are generally provided with lubricating oil circuits for lubricating the middle plate, tail plate, head plate, machine hinge (connected between the middle plate and the tail plate), arm assembly (used to lock the guide column) and guide columns. The lubricating oil circuit transports the lubricating oil to the above-mentioned components through an oil pump and a pipeline for lubrication. The middle plate, as a moving template, is a component that often moves, and the machine hinge connected to the middle plate also often moves. Therefore, these components need to be lubricated frequently, while the tail plate, arm assembly and guide column are generally moved when the mold is installed or disassembled or debugged. Therefore, these components do not need to be lubricated frequently. In the existing lubricating oil circuit, the lubricating oil will be pumped to all the components to be lubricated when the oil pump is started. For the components that do not need to be lubricated frequently, it is undoubtedly a waste of lubricating oil.
[0003] Therefore, further improvements are necessary. Utility Model Content
[0004] The utility model aims to provide a lubricating oil circuit of a horizontal extrusion casting machine which has a simple structure, is stable and reliable, saves resources, has a low cost and is highly practical, so as to overcome the shortcomings of the prior art.

[0006] The first branch oil circuit includes a first branch trunk circuit, a tail plate arm guide post lubrication branch circuit and a head plate arm guide post lubrication branch circuit. One end of the first branch trunk circuit is connected to the main oil circuit, and the other end is respectively connected to the tail plate arm guide post lubrication branch circuit and the head plate arm guide post lubrication branch circuit.
[0007] The first solenoid valve is arranged on the first branch trunk line.
[0008] The first solenoid valves are respectively arranged on the lubrication branch of the tail plate guide post and the lubrication branch of the head plate guide post.

One end of the second branch trunk circuit is connected to the main oil circuit, and the other end is respectively connected to the left middle plate machine hinge lubrication branch circuit and the right middle plate machine hinge lubrication branch circuit.
[0010] The main oil circuit is provided with a second solenoid valve for opening or closing the main oil circuit.

[0013] The oil pump is provided with an oil pressure gauge for monitoring the oil pressure inside the oil pump.
[0014] A filtering component is provided on the main oil circuit.
[0015] The utility model provides an oil pump, a main oil circuit, a first branch oil circuit and a second branch oil circuit. The first branch oil circuit is provided with a first solenoid valve for conducting or cutting off the first branch oil circuit. After the oil pump is started, the middle plate, the machine hinge and other components can be lubricated through the second branch oil circuit. If it is necessary to lubricate the tail plate, the head plate, the bracket assembly and the guide column and other components, the first solenoid valve can be opened to make the first branch oil circuit conducting. If it is not necessary to lubricate the tail plate, the head plate, the bracket assembly and the guide column and other components, the first solenoid valve can be closed to cut off the first branch oil circuit. Therefore, the delivery of lubricating oil can be controlled as needed, so as to avoid wasting lubricating oil, save resources and reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS
