Description

Technical Field

[0001] The utility model relates to the field of oil seal moulds, in particular to an oil seal mould which is easy to demould. Background Art

[0002] Oil seal, also known as shaft seal, is a device part used in machines to prevent fluid (mostly lubricating oil) from escaping from joints (mostly the joint surfaces of parts or rotating shafts); in the process of producing oil seals, the ring material can be hot-pressed into shape through a mold.

[0003] According to a Chinese patent with publication number CN219191003U, an oil seal mold that is easy to demold is disclosed. The utility model adds structures such as a lifting frame, a guide rod and a spring inside the mold box. After the lower molding ring is molded inside, the lower molding ring on the lifting frame can be driven to rise by the elastic force of the spring. After the lower molding ring is raised, the oil seal formed inside is propped up, so that the oil seal can stay on the outside of the mold box, thereby making the oil seal easier to demold.

[0004] Regarding the above-disclosed patent content, since the depth of the upper molding ring and the lower molding ring is difficult to adjust, when oil seals of different thicknesses need to be formed, the lower molding ring needs to be removed from the mold and then replaced with molding rings of different depths to produce oil seals of different thicknesses. The disassembly and replacement process is complicated and will consume a lot of time, thereby reducing the efficiency of adjusting the depth of the molding ring and reducing the applicability of the mold. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an oil seal mold that is easy to demould, so as to solve the technical problem that it is inconvenient to adjust the depth of the molding ring in order to produce oil seals of different thicknesses.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oil seal mold that is easy to demold, comprising a base plate, a mold is installed at the middle position of the top of the base plate, a lower molding ring is installed inside the mold, an adjustment component is arranged at the bottom of the base plate, and the adjustment component comprises a fixed plate and a mounting plate installed at the bottom of the base plate and a movable plate arranged inside the mold, racks that penetrate the mold and the base plate are installed on both sides of the bottom of the movable plate, a movable rod is connected to one side of the rack, and a heat-conducting ring is installed on the top of the movable rod, a driven gear is arranged on the mounting plate, a motor is installed on the outer surface of the fixed plate, and a driving gear is connected to the output end of the motor.

[0007] By adopting the above technical solution, when the forming thickness needs to be adjusted, the user can start the motor, and the motor can drive the driving gear to rotate, and then drive the driven gear to rotate.

[0008] Furthermore, an electric heating rod is installed at the lower part of the interior of the mold, and the electric heating rod is located directly below the heat conductive ring.

[0009] By adopting the above technical solution, when the electric heating rod is working, it will heat the air, and the heat-conducting ring can conduct heat, thereby heating the ring material.

[0010] Furthermore, a support frame is installed on the top of the base plate, and a cylinder is installed on the top of the support frame.

[0011] By adopting the above technical solution, the support frame can support the cylinder. When the cover plate needs to be moved, the user can start the cylinder, and the operation of the cylinder can make the piston rod extend and retract, thereby driving the cover plate to move.

[0012] Furthermore, a cover plate is installed at the output end of the cylinder through a piston rod, and the cover plate is located directly above the mold.

[0013] By adopting the above technical solution, when the cover plate moves downward, it will drive the upper molding ring to move downward, thereby making the upper molding ring contact with the lower molding ring.

[0014] Furthermore, two sliding rods are fixed between the support frame and the bottom plate, and a sliding seat is sleeved on the outer wall of the sliding rod, and the sliding seat is connected to the cover plate.

[0015] By adopting the above technical solution, the sliding seat can slide on the sliding rod, thereby guiding the cover plate.

[0016] Furthermore, the cover plate is slidably connected to the slide rod via a slide seat, and an upper molding ring is provided at the bottom of the cover plate.

[0017] By adopting the above technical solution, when the cover plate moves, it will drive the slide seat to slide on the slide rod, thereby improving the stability of the cover plate when moving.

[0018] Furthermore, the driven gear is meshed with the driving gear, and both the driven gear and the driving gear are meshed with the rack.

[0019] By adopting the above technical solution, when the driving gear rotates, it will drive the driven gear to rotate, and the driving gear and the driven gear rotate simultaneously, which will drive the rack to move simultaneously.

[0020] Furthermore, the heat-conducting ring is located below the inner part of the lower molding ring, and the outer wall of the heat-conducting ring is in contact with the inner wall of the lower molding ring.

[0021] By adopting the above technical solution, the formed oil seal can be pushed out when the heat-conducting ring moves upward, thereby improving the efficiency of removing the oil seal.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model is provided with an adjustment component. When the thickness of the oil seal needs to be adjusted, the user can start the motor. The motor can drive the active gear to rotate, and then drive the driven gear to rotate. When the driven gear and the active gear rotate at the same time, they will drive the two racks to move at the same time, and then drive the movable rod to move, and then drive the heat conductive ring to move, so as to adjust the position of the heat conductive ring in the lower molding ring, thereby adjusting the thickness of the oil seal molding. In this way, oil seals of different thicknesses can be molded without disassembling the molding ring. The adjustment process is simple and convenient, and the use effect and applicability of the mold are improved. When the molded oil seal needs to be ejected, the above steps can be repeated so that the rack drives the movable rod to move upward, and then drives the heat conductive ring to move upward, so that the heat conductive ring completely ejects the oil seal from the molding ring, so as to avoid the molded oil seal being attached to the inner wall of the molding ring and being difficult to remove, thereby improving the removal efficiency of the oil seal.
