Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the structural schematic diagram of conventionally employed manual mode filling lubrication.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figure 1, a kind of automatic grease lubrication structure of plastic-injection moulding machine, the automatic grease lubrication structure include
Oil pump motor group 3, distributor 5, fuel tank 1, electromagnetic direction valve 4, pressure sensor 9, pressure gauge 8 and controller 7, in fuel tank 1
Equipped with lubricant grease, oil pump motor group 3 is connected with fuel tank 1, and the pipeline between oil pump motor group 3 and fuel tank 1 is equipped with filtering
Device 2, distributor 5 are connected by main line with oil pump motor group 3, and pressure sensor 9 is mounted on the end of working connection, electromagnetism side
It is arranged on main line to valve 4, for controlling being opened or closed for main line, pressure gauge 8 is arranged in electromagnetic direction valve 4 and oil pump
On main line between groups of motors 3, for monitoring the pressure of main line, and between electromagnetic direction valve 4 and oil pump motor group 3
Overflow valve 6 is installed, overflow valve 6 one terminates lubricant passage way main oil pipe, and other end connected tank prevents from pressing in main line on main line
Power is excessively high, plays safeguard protection；Distributor 5 is adding pressure type volume distributor, is connected with multiple branch pipelines on distributor 5, point
Pipeline is connected with each oil site of mould adjusting mechanism, and when oil mass reaches certain pressure value in distributor 5, distributor 5 can be incited somebody to action
Quantitative grease is conveyed into branch pipeline, injects oil site；Pressure sensor 9, pressure are provided in the mode transfer lubricant passage way of oil site
