It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0021] According to the above structure, during use, when the upper mold of the press moves upward, the top of the mold pushes the closing component 2 upward, the oil leakage groove 18, the oil guide groove 19 and the oil outlet hole 111 are opened, and the closing component 2 moves while pushing the oil pushing component 4 upward. The oil pushing component 4 squeezes the lubricating oil between the oil storage cylinder 14 and the inner cylinder 11 from the oil leakage groove 18, and the lubricating oil flows along the oil guide groove 19 and the oil outlet hole 111 to the bottom end of the tapered end 17, and flows along the bottom end of the tapered end 17 to the column, thereby lubricating the column. The lubricating oil is evenly extruded and evenly applied to the column to improve the lubrication effect. The lubricating oil can be squeezed out each time the mold rises, further improving the lubrication effect.
[0022] like Figure 2 and 3 As shown, a separation cylinder 16 is provided between the inner cylinder 11 and the oil storage cylinder 14 , the bottom end of the separation cylinder 16 is fixedly connected to the inner wall of the conical cylinder 13 , and a connecting plate 110 is fixedly connected to the middle of the outer wall of the conical cylinder 13 .
[0023] According to the above structure, the separation cylinder 16 divides the space between the oil storage cylinder 14 and the inner cylinder 11 into two parts. When in use, the oil pushing component 4 moves upward to squeeze the lubricating oil downward.
[0024] like Figure 3 and 4 As shown, the closing component 2 includes a cylinder 21 slidably connected to the outside of the tapered end 17, the bottom end of the cylinder 21 is fixedly connected to a bottom edge 22, the inside of the cylinder 21 is fixedly connected to an annular support plate 23, the bottom end of the annular support plate 23 is fixedly connected to a connecting cylinder 24, the bottom end of the connecting cylinder 24 is fixedly connected to an annular plugging plate 25, the connecting cylinder 24 is slidably connected to the outer wall of the outer cylinder 12, the bottom end of the annular plugging plate 25 is fixedly connected to a plug 26 that matches the oil guide groove 19, and one end of the plug 26 is fixedly connected to a plug column 27 that matches the oil outlet hole 111.
[0025] According to the above structure, when in use, the mold moves upward to a certain position and then pushes the bottom edge 22 upward by 3-8 mm. The bottom edge 22 drives the cylinder 21, the annular support plate 23 and the connecting cylinder 24 to move upward. At this time, the bottom of the oil leakage groove 18 leaks out, and the plug 26 and the plug 27 slide out from the corresponding oil guide groove 19 and the oil outlet hole 111 respectively. The lubricating oil can flow out along the oil guide groove 19 and the oil outlet hole 111.

[0028] The working principle of the utility model is as follows: when in use, the mold moves upward to a certain position and then pushes the bottom edge 22 to move upward by 3-8 mm, and the bottom edge 22 drives the cylinder 21, the annular support plate 23 and the connecting cylinder 24 to move upward. At this time, the bottom of the oil leakage groove 18 leaks out, and the plug 26 and the plug 27 slide out from the corresponding oil guide groove 19 and the oil outlet hole 111 respectively, and the lubricating oil can flow out along the oil guide groove 19 and the oil outlet hole 111.

When the mold moves downward, the sealing component 2 moves downward as a whole under the elastic force of the spring 43, driving the annular piston 41 to move downward, and the lubricating oil in the external oil tank enters between the oil storage cylinder 14 and the inner cylinder 11 through the oil inlet pipe 32. The setting of the one-way valve 33 can only allow the lubricating oil to flow from the outside of the oil storage cylinder 14 to the inside.
[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
