Description

Technical Field

[0001] The utility model relates to the technical field of diamond drill bit production, in particular to a diamond drill bit production mold. Background Art

[0002] The rock-breaking effect of a diamond drill bit is accomplished by diamond particles. To understand the rock-breaking effect of a drill bit, one must understand the rock-breaking effect of a single diamond. In hard formations, a single diamond particle, under the action of drilling pressure, puts the rock under an extremely high stress state (about 4200-5700 MPa, and some data suggest it can reach 6300 MPa), causing the rock to undergo a lithology transformation from brittle to plastic.

[0003] The Chinese patent publication number CN112387971A discloses a diamond drill bit production mold. This patented technology is provided with threads, fixing rings and anti-slip grooves. When the inner mold needs to be replaced, the staff rotates the inner mold by holding the fixing ring. Since the inner mold and the outer mold are connected by threads, the inner mold can be disassembled. The anti-slip grooves can increase friction, making rotation more convenient. After disassembly, the staff can then replace other inner molds and mold petals.

[0004] However, in the preparation process of existing diamond drill bits, personnel need to use hydraulic equipment to apply high pressure to the drill bit raw material filled in the mold before firing to shape it. The threaded connection can easily cause the applied pressure to damage the thread, resulting in slippage or deformation of the thread structure, which may make it inconvenient for personnel to install and disassemble the outer mold and the inner mold. Therefore, it still has certain shortcomings in actual use.

[0005] In summary, it is necessary to invent a diamond drill bit production mold. Utility Model Content

[0006] To this end, the utility model provides a diamond drill bit production mold to solve the problem that the pressure applied through threaded connection may easily damage the thread, causing slippage or deformation of the thread structure, making it inconvenient for personnel to install and disassemble the outer mold and inner mold.

The outer walls of the fixing plug plates are slidably connected to the inner walls of the corresponding mounting holes, and a pull block is fixed to the end of the fixing plug plate away from the outer mold.

[0011] Preferably, a water cooling groove for the coolant to pass through is provided on the inner wall of the forming inner mold and between the mounting sockets. The water cooling groove surrounds the inner wall of the forming inner mold. A liquid inlet is provided on the left side of the outer wall of the water cooling groove, and a liquid drain is provided on the right side of the outer wall of the water cooling groove.

Specifically, after the personnel place the forming inner mold 300 in the insulation layer 200, the mounting holes provided on the forming inner mold 300 will be aligned with the mounting holes provided on the outer mold 100 and the insulation layer 200. After the mold 100 is assembled, the mold 100 is assembled into the mold base 300, and the mold base 300 is assembled into the mold base 300. After the mold 100 is assembled, the mold base 300 is assembled into the mold base 300, and the mold base 300 is assembled into the mold base 300. After the mold 100 is assembled, the mold base 300 is assembled into the mold base 300, and the mold base 300 is assembled into the mold base 300. After the mold 100 is assembled, the mold base 300 is assembled into the mold base 300, and the mold base 300 is assembled into the mold base 300.

[0027] The inner forming mold 300 is provided with a material taking component, which includes a bottom sealing plug rod 350. The inner forming mold 300 and the forming block 310 are provided with a through groove below each drill bit forming groove 311. The outer wall of the bottom sealing plug rod 350 is slidably connected with the inner wall of the through groove, and a certain damping can be set between the bottom sealing plug rod 350 and the through groove to improve the connectivity between the bottom sealing plug rod 350 and the through groove. In the absence of external force, the bottom sealing plug rod 350 can be prevented from being separated from the through groove. The bottom sealing plug rod 350 can be taken out of the through groove during subsequent material taking. In this way, personnel can use a short rod through the through groove to knock on the formed drill bit when taking out the component, and use the vibration generated by the drill bit to accelerate its In order to achieve the effect of detaching from the drill bit forming groove 311, an upper pressing die 400 is arranged above the top of the outer wall of the outer mold 100, and a pressure block 410 is fixed at the bottom end of the outer wall of the upper pressing die 400 and at a position corresponding to the drill bit forming groove 311, and a positioning pin shaft 420 is fixed at the corners of the bottom end of the outer wall of the upper pressing die 400.
