一种应用于下模工作台液压缸与油箱之间的连接装置
By setting a second connector with a side connection between the hydraulic cylinder and the oil tank, the hydraulic oil can quickly enter the oil cylinder by utilizing the pressure difference and height difference, which solves the problem of long hydraulic oil delivery distance and improves the working efficiency of the injection molding machine.

AI Technical Summary
In injection molding machines, due to the height difference between the oil tank and the hydraulic cylinder, the hydraulic oil has to travel a long distance from the oil tank to the oil cylinder, resulting in slow filling speed of the oil chamber and long pressurization time, which affects work efficiency.
Design a connecting device in which the connecting part 2 between the hydraulic cylinder and the oil tank is connected to the side of the oil tank, with a height difference greater than the height difference between the connecting part and the top of the oil tank. The connecting part 2 is connected to the inside of the oil tank. The hydraulic oil can be quickly entered into the oil cylinder through the pressure difference and height difference, reducing the delivery distance.
It shortens the time for hydraulic oil to enter the cylinder and improves the working efficiency of the injection molding machine's lower mold worktable.
