Description

A mold for reducing the damage of steering knuckle

Technical Field

The utility model relates to the technical field of automobile steering knuckle casting, in particular to a mold for reducing the bump damage of the steering knuckle.

Background Art

As is known, the steering knuckle is a very important component in the automobile braking system. If a failure occurs, it will have a great impact on driving safety. It can make the car run stably and sensitively transmit the driving direction. The steering knuckle is generally heavy and is prone to scrapping castings due to bumps and scratches, resulting in increased production costs.

At present, in the foundry industry, in order to avoid bumps and bruises, independent anti-collision blocks are generally added to the locations prone to bumps and bruises to reduce the occurrence of bumps and bruises, but this method also has disadvantages. This process can protect castings and reduce the occurrence of bumps and bruises, but due to the different sizes of castings, different layouts, and different casting process designs, some products cannot add independent anti-collision blocks, and independent anti-collision blocks are prone to partial meat when cleaning the steering knuckle trim, causing the casting to be scrapped.

In view of the above reasons, a mold for reducing the damage to the steering knuckle has been developed.

Utility Model Content

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a mold for reducing the bumps and scratches on the steering knuckle. The anti-bump patch is cast and formed integrally with the casting, and there will be no situation in which the independent anti-bump block is carried with meat when the steering knuckle is trimmed and cleaned, causing the casting to be scrapped; the casting is placed symmetrically, and the anti-bump patch is poured on the outward side of the part of the casting that is prone to bumps and scratches to offset the material shortage caused by the bumps and scratches. At the same time, compared with the production material consumption of the independent anti-bump block, the production material consumption of the anti-bump patch can be saved by at least 95%, reducing the proportion of scrap products due to bumps and scratches, and can significantly improve production efficiency, increase the casting yield rate, and reduce production costs.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mold for reducing the damage of the steering knuckle, including a mold cavity, a pouring system and a mold core, the pouring system includes a sprue, a pouring cup, a cross runner, a filter, a main riser, a sub-riser, a bottom water inlet, a side water inlet, and a water inlet; the pouring cup is arranged at the middle of the upper end of the mold cavity, the upper end of the sprue is vertically connected to the pouring cup, water inlets are arranged on the mold cavity on both sides of the upper end of the sprue, a filter is arranged at the lower end of the sprue, a pair of mold cores are symmetrically arranged on the left and right sides of the sprue, and the middle of the upper end of the left mold core and the right mold core are symmetrically arranged. The middle part of the upper end corresponds to the connected auxiliary riser, the right side of the left mold core and the left side of the right mold core correspond to the connected main riser, the left side of the left mold core and the right side of the right mold core correspond to the upper end of the connected side water inlet, the left side of the lower end of the left mold core and the right side of the lower end of the right mold core correspond to the upper end of the connected bottom water inlet, a cross runner is arranged under a pair of mold cores, the lower end of the straight runner is vertically connected with the middle part of the cross runner, a pair of main risers are respectively connected with the cross runner, the lower end of a pair of bottom water inlets and the lower end of the side water inlet are respectively connected with the cross runner, and at least three anti-collision casting cavities are arranged on the mold core.

Furthermore, the anti-collision casting cavity is semi-cylindrical, and the arc surface of the semi-cylindrical anti-collision casting cavity faces outward.

The utility model has the following beneficial effects: molten iron enters the sprue through the pouring cup, flows into the filter screen through the sprue, and the filtered molten iron enters the cross runner. The molten iron is respectively filled with the casting through the bottom water inlet, the side water inlet, and the main riser of the cross runner, and part of the molten iron enters the auxiliary riser through the water inlet to fill the casting. After the casting is cooled and sheared and separated, during the shot blasting and transportation turnover process, the anti-collision patch faces outward, and in case of collision, the anti-collision patch is collided first, so as to prevent the collision from damaging the casting body and causing scrap caused by collision.

The anti-collision patch of the utility model is integrally cast with the casting, and there will be no situation in which the independent anti-collision block is carried with meat when the steering knuckle is trimmed and cleaned, causing the casting to be scrapped; the casting is placed symmetrically, and the anti-collision patch is poured on the outward side of the part of the casting that is prone to bumps and scratches, so as to offset the material shortage caused by bumps and scratches. At the same time, compared with the production material consumption of independent anti-collision blocks, the production material consumption of the anti-collision patch can be saved by at least 95%, reducing the proportion of scrap caused by bumps and scratches, which can significantly improve production efficiency, increase the casting yield rate, and reduce production costs; the parts not described in detail in the utility model are existing commonly used technologies.
