Description

Technical Field

[0001] The utility model relates to the field of oil valve control devices, in particular to a hot runner oil cylinder system with a stepped structure. Background Art

[0002] In the hot runner valve pipeline, when the pressure at the outlet is too high, it affects the normal flow of the medium. The pressure reducing valve is a valve that can automatically open and close according to the working pressure of the system. When the pressure at the outlet is greater than the specified pressure, the pressure reducing valve will automatically close to achieve the effect of pressure reduction and ensure the stability of the pipeline.

[0003] When the oil pressure of multiple hot runner devices needs to be controlled simultaneously, the existing control device generally needs to be controlled one by one to achieve the distribution of the oil circuit. Although the installation is simpler, the equipment layout is relatively messy, so a larger space is required to install the oil valve controller. Utility Model Content

[0004] The main purpose of the utility model is to propose a hot runner cylinder system with a stepped structure, aiming to design an oil valve control device that can realize the separate control of multiple groups of oil circuits, and has a simple and stable structure and a small size, which is conducive to improving the neatness of the equipment layout.

[0005] To achieve the above-mentioned purpose, the utility model proposes a hot runner cylinder system with a stepped structure, comprising:

[0006] A cylinder body, wherein the cylinder body is provided with a main fluid input channel and a main fluid output channel along its length direction, the main fluid input channel is connected to a main input control valve, and the main fluid output channel is provided with a main output control valve;

[0007] A flow splitting structure, the flow splitting structure comprising a first branch flow channel, a second branch flow channel, a third branch flow channel and a fourth branch flow channel vertically arranged on the cylinder body, the first branch flow channel being connected to the main fluid input channel, and the second branch flow channel being connected to the main fluid output channel;

[0008] A branch control valve, wherein at least two branch control valves are provided, and the branch control valve is provided on the upper wall of the cylinder body. The branch control valve is provided with a first solenoid valve and a second solenoid valve, and the first solenoid valve is used to control the connection or disconnection between the upper end of the first branch flow channel and the upper end of the second branch flow channel;

[0009] The second solenoid valve is used to control the connection or disconnection between the upper end of the third branch flow channel and the fourth branch flow channel;

[0010] A hot runner device is provided between the lower end of the second branch flow channel and the lower end of the third branch flow channel.

[0011] In actual control, the high-pressure liquid passes through the main fluid input channel, the first branch flow channel, the first solenoid valve, the second branch flow channel, the hot runner device, the third branch flow channel, the fourth branch flow channel and the main fluid output channel in sequence.

[0012] First, by setting the main fluid input channel and the main fluid output channel, multiple branch control valves can be set at the interval of the cylinder body, so the power source can be distributed to multiple hot runner devices, and its structural design is relatively simple and small in size, thus avoiding a messy working environment; at the same time, through a reasonably designed branch structure, the power source of each hot runner device can be accurately controlled.)
