The beneficial effect who so sets up is: by adopting the scheme, the outer diameter of the large section of the upper die of the retainer is increased by the large section of the upper die, so that the integral strength of the product is effectively improved.
The utility model discloses further set up as the window of flexible holder is provided with holder window fillet.
The beneficial effect who so sets up is: by adopting the scheme, the window of the flexible retainer is provided with the retainer window fillet, so that the flexible retainer can be effectively prevented from being broken due to stress concentration caused by the fact that the window is not provided with the fillet.
The utility model discloses further set up to the surface of die parting face has been seted up die parting face draft angle.
The beneficial effect who so sets up is: by adopting the scheme, the outer surface of the die parting surface is provided with the die parting surface draft angle, so that the product can be effectively and conveniently demoulded after injection molding.
The utility model discloses further set up to tapered roller bearing outer lane with tapered roller bearing inner circle adopts alloy steel material, and is in tapered roller bearing outer lane with the inside of tapered roller bearing inner circle is provided with lubricating oil.
The beneficial effect who so sets up is: by adopting the scheme, the rigidity of the outer ring of the tapered roller bearing and the inner ring of the tapered roller bearing can be effectively improved by adopting alloy steel materials, and the friction force can be effectively reduced by the arranged lubricating oil, so that the service life is prolonged.
The utility model discloses further set up to the through-hole has been seted up to the surface of flexible holder, just flexible holder adopts flexible material.
The beneficial effect who so sets up is: by adopting the scheme, the through hole is formed in the outer surface of the flexible retainer, so that the bearing roller can be effectively and conveniently placed.
