After the lower bearing seat 2 and the upper bearing seat 7 are closed and fixed, annular packaging gaskets 3 are arranged at both front and rear ends of both, and the annular packaging gasket 3 is fixedly connected to the lower bearing seat 2 and the upper bearing seat 7 by multiple screws. The diameter of the internal circular hole of the annular packaging gasket 3 is smaller than the diameter of the semicircular bearing fixing groove A8 and the semicircular bearing fixing groove B10, and the annular packaging gasket 3 is equal to or larger than the internal diameter of the bearing.
[0022] like Figure 1 and Figure 2 As shown, when assembling and using the high-precision bearing seat for injection molding machine, it is first necessary to ensure that the lower bearing seat 2 and the upper bearing seat 7 are in the disengagement device, and then it is necessary to determine the installation and use position of the high-precision bearing seat for injection molding machine on the injection molding machine, and then fit the mounting and fixing base plate 1 at the bottom of the lower bearing seat 2 to the installation position, and use screws to pass through the mounting and fixing holes 4 and firmly fix the mounting and fixing base plate 1 on the injection molding machine. After the lower bearing seat 2 is fixed by the mounting and fixing base plate 1, it is necessary to install the bearing into the lower bearing seat 2. Specifically, it is necessary to insert the lower half of the bearing into the interior of the semicircular bearing fixing groove A8, and after the lower half of the bearing is inserted, the anti-disengagement rings 9 on the inner walls of the front and rear ends of the semicircular bearing fixing groove A8 are respectively clamped at the front and rear ends of the lower half of the bearing to prevent the bearing from displacement during operation, and then it is necessary The upper bearing seat 7 is connected to the outside of the upper half of the bearing through the semicircular bearing fixing groove B10.

Then, multiple fixing bolts 6 are needed to be used to fix the lower bearing seat 2 and the upper bearing seat 7 at both ends, so that the bearing can be firmly fixed inside the lower bearing seat 2 and the upper bearing seat 7. Finally, two annular sealing gaskets 3 need to be respectively attached to the outer walls at the front and rear ends of the lower bearing seat 2 and the upper bearing seat 7 in the closed state, and the annular sealing gaskets 3 are fixed with screws. The annular sealing gaskets 3 can avoid oil leakage and also can provide protection on the outside of the front and rear ends of the bearing, thereby providing guarantee for the efficient operation of the bearing.
[0023] like Figure 1 , Figure 3 and Figure 4 As shown, a self-lubricating device 5 is provided at the center of the top of the upper bearing seat 7, and the self-lubricating device 5 includes an oil supply seat 11, a sealing sheet 12, an oil supply screw hole 13, an oil supply screw 14 and an operating head 15. The oil supply seat 11 is fixed at the center of the top of the upper bearing seat 7. The upper end of the oil supply seat 11 is fixed with a sealing sheet 12 by a plurality of screws. The center of the sealing sheet 12 is provided with an oil supply screw hole 13. The inner thread of the oil supply screw hole 13 is plugged with the oil supply screw 14. The top of the oil supply screw 14 is provided with an operating head 15. The self-lubricating device 5 also includes an oil supply hole 16, an elastic self-shrinking rubber ring 17, an oil supply plunger 18 and an oil storage chamber 19. An oil storage chamber 19 is provided inside the seat 11, an oil supply hole 16 is provided inside the center of the top end of the upper bearing seat 7, and the oil supply hole 16 is connected to the inside of the oil storage chamber 19, an elastic self-shrinking rubber ring 17 is provided inside the oil supply hole 16, an oil supply plunger 18 is provided inside the oil storage chamber 19, and the oil supply plunger 18 is fixedly connected to the bottom end of the oil supply screw 14, the operating head 15 can manually drive the oil supply screw 14 to rotate clockwise or counterclockwise, and the oil supply screw 14 can move up and down in the oil supply screw hole 13 through the pushing action of the thread when rotating clockwise or counterclockwise, and the oil supply screw 14 can drive the oil supply plunger 18 to move up and down inside the oil storage chamber 19 when moving up and down.
[0024] like Figure 1 , Figure 3 and Figure 4As shown, the oil storage chamber 19 at the bottom area of the oil supply plunger 18 is injected with bearing lubricating oil. The oil supply plunger 18 is made of soft rubber, and there is an interference fit between the oil supply plunger 18 and the oil storage chamber 19. The internal circular hole of the elastic self-contracting rubber ring 17 is closed by the elastic contraction of the rubber ring itself. When the self-lubricating device 5 is in a normal state, the oil supply plunger 18 is now inside the top of the oil storage chamber 19, and the bottom area of the oil supply plunger 18 is filled with bearing lubricating oil, so that more bearing lubricating oil can be stored in the oil storage chamber 19 to a greater extent, and the elastic self-contracting The shrink rubber ring 17 is in a shrunken and closed state, which will directly block the oil supply hole 16, ensuring that a certain amount of bearing lubricating oil can be stored in the oil storage chamber 19 all the time.

Specifically, it is necessary to grasp the operating head 15 and drive the oil supply screw 14 to rotate counterclockwise. The counterclockwise rotating oil supply screw 14 and the oil supply screw hole 13 inside the sealing gasket produce a threaded pushing effect, which will The oil supply screw 14 moves downward, and the downward movement of the oil supply screw 14 will drive the oil supply plunger 18 to move downward. The downward movement of the oil supply plunger 18 will press the bearing lubricating oil downward. After the bearing lubricating oil is pressed into the oil supply hole 16 by the oil supply plunger 18, an extrusion force is applied to the elastic self-shrinking rubber ring 17, which will cause the bearing lubricating oil to flush open the circular hole automatically closed by the elastic self-shrinking rubber ring 17, so that the bearing lubricating oil can smoothly pass through the oil supply hole 16 and plunger to the bearing. The lubricating oil delivered to the bearing will slowly permeate the entire bearing The purpose of quickly adding lubricating oil to the bearing is achieved, and when the oil supply screw 14 stops rotating, the oil supply plunger 18 will stop in the oil storage chamber 19, which will stop the delivery of the bearing lubricating oil. At this time, the elastic self-contracting rubber ring 17 will lose the extrusion force applied by the lubricating oil, which will cause the elastic self-contracting rubber ring 17 to be closed again through the elastic contraction of the rubber ring itself, preventing the lubricating oil from continuing to pass through the oil supply hole 16, so that the remaining lubricating oil can continue to be stored in the oil storage chamber 19, ensuring that the bearing can continue to be added with lubricating oil next time.
