Abstract
The utility model discloses a mould for casting wheel hubs of an electric motorcycle. The mould comprises an upper mould, a lower mould and a side mould which are mutually matched, wherein inner cavities of the upper mould, the lower mould and the side mould are combined to form a wheel hub cavity; the wheel hub cavity is in an inverted structure that the end cover cavity of a wheel hub is arranged at the lower part; the end cover cavity of the wheel hub is arranged on the lower mould; and the top part of the upper mould is provided with a casting port. The mould for casting the wheel hubs is suitable for the inversion casting technology; the casting is conducted when the end cover is arranged at the lower part, and inserts are arranged at the upper part, and the thickness of an end cover blank of one wheel hub can be only 0.1-0.5mm thicker than that of the finished product; and if no special requirements are asked for the appearance, the end cover blank of the wheel hub can be directly manufactured into the size of the finished product.
Description
Technical field
The utility model relates to electric motorcycle wheel hub casting technique.
Background technology
The end cap that general electric vehicle hub adopts is last, inserts under the casting mode.But battery-operated motor cycle because of its particular structure (end cap and wheel hub one, as shown in the figure), end cap partial mirror diameter reaches 300mm, as adopts common positive pouring technique to be easy to generate to contract and send casting flaws such as slag inclusion; And will be to the effective feeding of bank spare patrix bank spare end face, it is thick will to increase meat, make whole electric motorcycle wheel hub hair training end cap thickness will by present 4.5 (+0.5^+1) MM directly becomes 10-15MM, the aluminium consumption is bigger, and the inner grain structure of end cap is thick, easy shrinkage porosite, difficult quality guarantee.
The utility model content
Technical problem to be solved in the utility model just provides a kind of electric motorcycle wheel hub casting die, uses this casting die to carry out wheel hub uphill running casting, can reduce the blank thickness of casting rear end cap, saves processing cost.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of electric motorcycle wheel hub casting die, comprise the upper die and lower die and the limit mould that cooperatively interact, the combination of lumens of upper die and lower die and limit mould constitutes the wheel hub die cavity, it is characterized in that: described wheel hub die cavity be the wheel hub end housing chamber under inverted structure, described wheel hub end housing chamber is arranged on the counterdie, and described patrix top is provided with casting gate.
Preferably, described counterdie is equipped with and supports locating piece support inserts, and described support locating piece upper end is provided with a step, the bottom of the described inserts of planar support of getting out of a predicament or an embarrassing situation of described step.
Preferably, described patrix lateral surface is the inclined-plane, patrix location to the inboard inclination in patrix lower end, and inclined-plane, described limit mould corresponding patrix location is provided with inclined-plane, mould location, limit.In uphill running casting process, at first to solve the relative positioning problem of inserts and whole wheel hub.For guaranteeing the position degree of inserts, counterdie is installed the 4-6 root and is supported locating piece, forms a supporting surface, to place inserts, as first location.The gradient targeting part of patrix continues in the matched moulds process at patrix according to inserts internal diameter automatic capturing location then, and by rational fit tolerance, further the centering inserts is finally located.
Preferably, described limit mould is provided with a valve that the is used for moulding valve cock mounting plane hole of inserting, and valve is installed in described valve is inserted the hole is inserted, and described limit mould is provided with valve inserted and is fastened on insert fastener in the hole of described valve.This air valve structure utilizes the die insert casting, still leaves the precasting platform behind wheel rim die cavity finish turning, does not need to arrange this procedure of counterbore after boring the oblique through hole of valve the vacuum valve cock can be installed directly again, and satisfies the air-tightness requirement.
Preferably, described fastener comprises and the described valve vertical screwed hole in hole of inserting, be provided with the fastening described valve of a holding screw in the described screwed hole and insert, described valve is inserted and is provided with a binding groove that snaps in for described holding screw top over against described holding screw position.
The utility model wheel hub casting die is applicable to the uphill running casting process, and end cap is following like this, and inserts is cast last, makes the wheel hub end housing blank thickness only than the thick 0.1^0.5MM of finished product, if outward appearance is not had specific (special) requirements, can directly accomplish finished size.The blank weight of the electric motorcycle wheel hub of the production of employing mould and this technology only accounts for half of existing casting mode, and manufacturing procedure can be simplified, and has saved cost greatly, and product quality does not descend simultaneously.
