Description

Technical Field

[0001] The utility model relates to the field of wheel hub bearing oil seal processing equipment, in particular to a mold used for processing wheel hub bearing oil seal. Background Art

[0002] The wheel hub bearing oil seal, also known as the wheel hub seal ring, is a sealing device used in the wheel hub of a vehicle. Its structural principle is to use rubber material, add a spring ring inside, and form an airtight pressure chamber between the sealing material and the surface of the shaft. In this way, when the steering external force centered on the shaft acts on the wheel hub, the wheel hub oil seal can adaptively maintain and protect the bearing and lubricating oil. When producing the wheel hub bearing oil seal, a mold for processing the wheel hub bearing oil seal is required.

[0003] During the production process of the existing mold for processing wheel hub bearing oil seals, it is necessary to apply a release agent to the inside of the mold slot, and the traditional application method is to manually apply it with a brush head. This method requires repeated manual operations, which increases the manual operation burden. Therefore, it is necessary to provide an oiling mechanism that can quickly oil the mold for processing wheel hub bearing oil seals, thereby reducing the operation burden and increasing the production speed. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a mold for processing a hub bearing oil seal, so as to solve the technical problem that the traditional mold for processing a hub bearing oil seal has a heavy operating burden during operation.

[0006] Two oil guide pipes are provided, and an extension plate is provided inside the two oil guide pipes. A Hall sensor is installed on the top of the extension plate. A magnetic induction sheet is provided on one side of the hot pressing seat.

[0007] By adopting the above technical solution, since an oiling mechanism is provided on one side of the base, the oiling mechanism includes an oil storage barrel, and the release agent can be effectively stored through the oil storage barrel.

[0008] Furthermore, the two oil guide pipes are mirror-arranged along the length center line of the oil storage barrel, the oiling mechanism is provided with two groups, and the two groups of the oiling mechanism are mirror-arranged along the width center line of the base, and an oil filling port is provided on the top of the oil storage barrel.

[0009] By adopting the above technical solution, since the two oil guide pipes are mirror-imaged along the length center line of the oil storage barrel, the two molds and mold grooves can be respectively taken care of by the two oil guide pipes.

[0010] Furthermore, extension frames are provided on both sides of the base, and a cylinder seat is installed on the top of the extension frame.

[0011] By adopting the above technical solution, since the extension frames are arranged on both sides of the base, the cylinder seat can be effectively fixed by the extension frames.

[0012] Furthermore, a piston rod is provided at the output end of the cylinder seat, a hot pressing seat is provided at the bottom of the piston rod, and four limiting rods are provided on the outer side of the piston rod.

[0013] By adopting the above technical solution, a piston rod is provided at the output end of the cylinder seat, and a heat pressing seat is provided at the bottom of the piston rod. Therefore, after the cylinder seat is started, the piston rod can be urged to rise or fall, thereby controlling the height of the heat pressing seat.

[0014] Furthermore, a mold is provided at the bottom of the hot pressing seat, a bottom plate is provided at the top of the base, a mold groove is provided at the top of the bottom plate, and the mold fits with the mold groove.

[0015] By adopting the above technical solution, since a mold is provided at the bottom of the hot pressing seat, a bottom plate is provided at the top of the base, and a mold groove is provided at the top of the bottom plate, the oil seal ring can be effectively processed and produced through the cooperation of the mold and the mold groove.

[0016] Furthermore, four of the molds and mold grooves are provided, and the four molds and mold grooves are arranged equidistantly in a rectangular array.

[0017] By adopting the above technical solution, since four molds and four mold grooves are provided, the molds and the mold grooves can quickly and synchronously process four oil seal rings.

[0018] Furthermore, the base, extension frame and cylinder seat are all made of stainless steel, and the mold and mold groove are all made of carbon alloy steel.

[0019] By adopting the above technical solution, since the base, extension frame and cylinder seat are all made of stainless steel, the base, extension frame and cylinder seat have excellent corrosion resistance and high temperature oxidation resistance, and can operate stably for a long time in harsh working environment.

[0020] Furthermore, the cylinder base and the oil pump are both electrically connected to an external controller.

[0021] By adopting the above technical solution, the cylinder seat and the oil pump can be directly controlled by an external controller.

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

[0023] 1. The utility model sets an oiling mechanism. When used for the first time, the oil pump is started by an external controller to prompt the oil pump to spray the release agent on the mold and the mold groove. When the oil seal is produced, it can avoid the oil seal from sticking during production, which causes the product to be defective. Subsequently, as long as the hot pressing seat is lowered, the magnetic induction sheet can be effectively used to trigger the Hall sensor. When the Hall sensor is triggered twice, the oil pump can be automatically started after ten or fifteen seconds to prompt the oil injection port to spray oil and oil the mold and the mold groove. The above arrangement can reduce the operation of manual oiling and improve the oiling efficiency.

[0024] 2. The utility model provides a visual window through which the content of the release agent inside the oil storage barrel can be visually and effectively observed, so that workers can efficiently add oil to the oil storage barrel, thereby avoiding the situation in which defective products are produced due to the failure of the release agent to be sprayed out immediately during long-term use.
