In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a take high pressure casting mould for wheel hub of brake spare part, includes die block, side form and top mould, be formed with the foundry goods die cavity between die block, side form and the top mould, the die block is formed with the mold core that upwards extends, die block or top mould are furnished with the first driver that is used for realizing die block or top mould lift, its characterized in that: the die core deviates from upper end department and is equipped with the support arch that extends in order to be used for supporting brake spare part to circumference outside, side form department is equipped with the second driver, side form be equipped with the cooperation groove of foundry goods die cavity intercommunication, be equipped with the locating part in the cooperation groove, the locating part is located relatively support protruding upside, the locating part translates under the second driver effect in order to be close to or keep away from the die core.
When the hub is required to be cast, the mould is opened firstly, the bottom mould or the top mould is lifted so as to expose the casting cavity, then the brake part is sleeved on the mould core of the bottom mould, then the mould is closed, the limiting piece is close to the mould core under the action of the second driver so as to prop against the brake part, and finally molten aluminum is led in so as to form a hub blank integrally arranged with the brake part. The utility model can realize the installation of the brake parts and the hub blank without welding, has lower requirements on the production process, can reduce the production procedures and lower the production cost.
The utility model adopts high-pressure casting, and high-pressure molten aluminum can impact the brake parts when being led in, so that the brake parts jump upwards; according to the utility model, the limiting piece is arranged, so that the brake part is limited to jump upwards in a mode that the limiting piece is propped against the brake part, and the connecting and fixing effect between the brake part and the hub blank is ensured.
Preferably, the supporting protrusion has a ring shape. The supporting bulge is annular, so that the contact area with the brake part is increased, and the positioning and supporting effects on the brake part are improved.
Preferably, the number of the limiting pieces is at least two. More limiting parts are arranged to press the brake parts, so that the condition that the brake parts are bounced up by high-pressure aluminum water is further avoided.
Preferably, the limiting piece is fixed with the side die, and the side die translates under the action of the second driver to drive the limiting piece to synchronously move. The side mould and the limiting piece move synchronously, namely the limiting piece is propped against the brake part when the side mould is closed, and meanwhile, the sliding fit treatment between the limiting piece and the side mould can be omitted.
Preferably, the inner and outer parts of the matching groove penetrate through the side die, and the outer end of the limiting piece is wide and the inner end of the limiting piece is small. The limiting piece with a certain length is arranged in the matching groove from outside to inside, so that a structure for preventing the limiting piece from falling off is not required to be arranged on the inner side of the side die, and the die is convenient to manufacture and assemble.
Preferably, the thickness of the end portion of the stopper is gradually reduced from the circumferential outer side to the core side. Through the setting so that the drawing of patterns between wheel hub blank and locating part.
The utility model simultaneously connects and fixes the brake parts and the hub during hub casting, and has the advantages of no need of welding, lower requirement of production process, reduction of production procedures and reduction of production cost.
Drawings
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is an enlarged view of the mold core of the present utility model.
Detailed Description
The utility model is further described below with reference to the drawings and specific embodiments.
As shown in fig. 1 and 2, this embodiment discloses a high-pressure casting mold for a hub with a brake component, which comprises a bottom mold 1, a side mold 2 and a top mold 3, wherein a casting cavity 100 is formed among the bottom mold 1, the side mold 2 and the top mold 3. Wherein, the top die 3 is matched with a first driver (not shown in the figure) for realizing the lifting of the top die,
the bottom die 1 is provided with a die core 11 extending upwards, a supporting protrusion 12 extending outwards in the circumferential direction is arranged at the position, deviating from the upper end, of the die core 11 and used for supporting the brake part 4, and an ejection assembly 200 used for facilitating demolding of a cast hub blank is arranged at the lower side of the bottom die 1. The supporting protrusion 12 of this embodiment is annular, and a plurality of annular protrusions 41 are disposed on the outer wall of the brake component 4.
The number of the side dies 2 is two, and the two side dies 2 are oppositely arranged and are respectively matched with a second driver 20, and the second drivers 20 are used for realizing the translational sliding of the side dies. The side die 2 is provided with a matching groove communicated with the casting cavity 100, a limiting piece 5 is arranged in the matching groove, the inside and the outside of the matching groove penetrate through the side die 2, and the wide inner end of the outer end of the limiting piece 5 is small so as to prevent the inner end of the limiting piece 5 from excessively extending into the casting cavity 100.
