Casting mold cleaning device for steering knuckle processing

Abstract

The invention relates to the field of mold cleaning, in particular to a casting mold cleaning device for steering knuckle processing. The device comprises a motor; an output shaft is installed at thelower end of the motor; a circular disc is installed at the bottom end of the output shaft; a rotating cylinder is installed on one side at the lower end of the circular disc; a hollow shelf is connected with the rotating cylinder in a contact mode; a horizontally moving rod is installed on the outer side of the hollow shelf; at least two driving teeth are fixed at the upper end of the horizontally moving rod; driven teeth are engaged with the driving teeth; a semicircular body is fixed at the upper end of the driven teeth; a driving spur gear is installed on the middle-upper part of the output shaft; a driven spur gear is connected with the driving spur gear via a closed rack; and an extending device is installed at the lower end of the driven spur gear. Through the arrangement of the hollow shelf, the rotating cylinder, the circular disc and the output shaft, the semicircular body moves left and right in a reciprocating mode, so the situation that a traditional brush fails to clean blind angles is avoided; and at the same time, the motor is used as a rotation power source, so the problems that a device of an electrolytic process occupies a large area and is high in energy consuming, and the electrolyte alkali concentration, temperature, electric current density and cleaning duration are difficult to control are avoided.

Description

technical field [0001] The invention relates to the field of mold cleaning, in particular to a casting mold cleaning device for steering knuckle processing. Background technique [0002] Steering knuckle, also known as "claw horn", is one of the important parts in the steering axle of a car, which can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel The pin rotates to turn the car. When the car is running, it bears variable impact loads. Therefore, it is required to have high strength. Casting molds refer to the use of other easy-to-form materials in advance in order to obtain the structural shape of the parts. Make the structural shape of the part, and then put it into the mold in the sand mold, so a cavity with the same structural size as the part is formed in the sand mold, and then a fluid liquid is poured into the cavity, and t...

[0002] Steering knuckle, also known as "claw horn", is one of the important parts in the steering axle of a car, which can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel The pin rotates to turn the car. When the car is running, it bears variable impact loads. Therefore, it is required to have high strength. Casting molds refer to the use of other easy-to-form materials in advance in order to obtain the structural shape of the parts. Make the structural shape of the part, and then put it into the mold in the sand mold, so a cavity with the same structural size as the part is formed in the sand mold, and then a fluid liquid is poured into the cavity, and the liquid can be cooled and solidified The parts with exactly the same shape and structure as the mold are formed. Casting molds are often used to produce steering knuckles in the production process. The steering knuckle casting molds need to be cleaned after being used for a certain number of times. However, the mold cleaning devices currently on the market, Generally, the bristles are used to contact the mold to clean the mold. Because the inner cavity of the casting mold is uneven, the bristles cannot fully contact the inner cavity of the casting mold, and the cleaning effect on the casting mold is not good.

[0003] After searching, the Chinese Patent No. is CN209663877U, which discloses a casting mold cleaning device for steering knuckle processing, including a cleaning box, the cleaning box is fixedly installed with an inner barrel through a pad installed at the bottom of the inner wall, and the interior of the inner barrel is fixed. Water blocking seat, the casting mold cleaning device for steering knuckle processing, through ultrasonic generator, electric telescopic rod, loading rack, electrolyte liquid filling pipe, inner barrel, extension rod, entrance and exit, driving device, mounting plate, rotating rod, electrolytic chamber 1. The transducer and the electrolyzer are used in conjunction. The electrolyzer electrolyzes the electrolyte to clean the dirt on the casting mold, and the transducer converts high-frequency electric energy into mechanical energy, thereby generating an impact force that causes damage to the surface of the casting mold. impact, accelerate the quick removal of dirt on the casting mold, and further improve the cleaning effect, and the rotation of the carrier allows the casting mold to fully contact with the electrolyte, improving the cleaning effect on the casting mold, and the cleaning effect on the casting mold is good, but the device The disadvantages are large floor area, high energy consumption and low cleaning efficiency, and it is difficult to control the alkali concentration, temperature, current density and cleaning time in the electrolyte.
