Description

Technical Field

[0001] The utility model belongs to the technical field of pressing rod moulds, and in particular relates to a mould pressing rod. Background Art

[0002] After cubic boron nitride and the catalyst are mixed, they need to be squeezed into a core column through a rod pressing machine mold. During the up and down pressing process of the mold, due to the excessive pressing pressure, after long-term use, the surface of the rod will be worn and scratched due to the error caused by the up and down movement, resulting in reduced assembly accuracy between the rod and the lower mold, further increasing the wear of the mold. Therefore, people often use a guide rod equipped with a linear bearing to assist in the positioning of the rod when it moves up and down.

[0003] However, in the existing rod pressing machine, when the rod pressing machine is guided and positioned by a guide rod equipped with a linear bearing, the rod pressing machine is fixed with multiple bolts, which makes it difficult to disassemble. During long-term use, it is not convenient to quickly replace the rod pressing machine after it is worn, and its practicality is low. Utility Model Content

[0004] The purpose of the utility model is to provide a mold pressing rod to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A mold pressing rod comprises a bottom plate and a movable plate arranged above the bottom plate;

[0007] A lower die is fixedly installed at the center of the top of the bottom plate, through holes are provided at the four corners of the bottom end of the movable plate, and linear bearings are fixedly installed in the through holes, a guide rod is slidably installed in the linear bearing, and the guide rod is fixedly connected to the top of the bottom plate, and a pressure component fixedly connected to the movable plate is constructed on both sides of the bottom plate, and a threaded assembly groove is provided at the center of the top of the movable plate, a through groove is provided at the center of the bottom end of the threaded assembly groove, and a pressing component passing through the through groove is detachably installed in the threaded assembly groove;

[0008] The pressing assembly comprises a pressing rod body movably arranged in the through groove, an outer edge surface top of the pressing rod body is configured with an external thread assembly ring, and the external thread assembly ring is thread-matched and installed in the thread assembly groove.

[0009] Furthermore, a forming groove is provided at the center of the top end of the lower mold, and the pressing rod body is inserted into the forming groove.

[0010] Furthermore, the top of the inner arc surface of the forming groove is provided with an annular chamfer 1 adapted to the pressing rod body, and the bottom end of the pressing rod body is provided with an annular chamfer 2 adapted to the forming groove.

[0011] Furthermore, the pressure-applying assembly includes a top plate, and hydraulic cylinders are fixedly mounted on both sides of the top of the top plate, and a piston rod of the hydraulic cylinder passes through one end of the top plate and is fixedly connected to the movable plate.

[0012] Furthermore, two support arms are symmetrically constructed on both sides of the top plate, and the support arms are welded and fixed to one side of the bottom plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Thanks to the arrangement of the bottom plate with the lower die installed and the movable plate with the pressing assembly detachably installed, the movable plate with four linear bearings installed inside is pushed up and down on the four guide rods by the pressure component, so as to guide the pressing assembly to be inserted into the lower die. When there is wear after long-term use, the pressing rod body can be twisted to drive the external thread assembly ring to rotate, so as to remove the pressing rod body with the external thread assembly ring installed in the threaded assembly groove on the movable plate, so as to facilitate the staff to replace the pressing rod body, which is more practical.

[0015] Thanks to the setting of the lower mold and the pressure rod body, the movable plate is pushed to move on the four guide rods by two hydraulic cylinders, so that the pressure rod body is inserted into the molding groove. The annular chamfer 1 on the molding groove and the annular chamfer 2 at the bottom of the pressure rod body can reduce the bumps that may be caused by the pressure rod body being inserted into the molding groove, greatly reducing the wear during mold closing, and the practicality is strong.
