Abstract
The utility model discloses a kind of low-pressure casting mould for wheel hub, form the counterdie of wheel hub casting mold cavity, side form and patrix after comprising combination, described side form is the frustroconical that one end is large, the other end is little, and described side form is provided with locked mode cover.The utility model eliminates column, cope match-plate pattern, reduces the assembly of mould, simplifies mould structure; Simplify matched moulds, demoulding step, achieve a kind of foolproof operation; Overcome the restriction of oil cylinder specification, effective raising die cavity withstand voltage, thus the crystallization and the density that improve product, the product strength waiting heavy aluminium water to produce is better than existing product, aluminium water weight needed for the product of same intensity reduces about 10%, effectively improves the competitiveness of product in market.
Description
Technical field
The utility model relates to casting mould field, is specifically related to a kind of low-pressure casting mould for wheel hub.
Background technology
Wheel hub be vehicle for connecting the parts of tire and axle, can be divided into one piece casting type, Integral forge type and combined type three kinds manufacturing process, wherein one piece casting type wheel hub is with the low advantage of cost, occupies about 90% of wheel hub total growth.The manufacture process of one piece casting type wheel hub is, by the die cavity of aluminium water and liquid aluminium alloy cast progressive die tool, forms demoulding cooling after wheel hub blank until aluminium water condensation, then carries out the fine finishining such as deburring, polishing, surface treatment and obtain wheel hub finished product; According to the difference of aluminium water pouring technology, be divided into gravitational casting and low pressure casting; The tubular that the structure of wheel hub is made up of wheel rim and spoke, for ease of the demoulding, its casting mould generally adopts upper die and lower die and side form to be combined to form hub casting mold cavity, low pressure casting needs to keep certain pressure after aluminium water cast progressive die tool, the sealing of die cavity is better, withstand voltage is higher, and the wheel hub quality cast out is better; Current low pressure casting die is respectively equipped with column in lower bolster corner, two sections of curved portions of composition side form are connected with the chute on column respectively by slide block, during cast, two sections of curved portions outer walls apply pressure to prevent pore respectively by the oil cylinder be oppositely arranged, die cavity withstand voltage limits by oil cylinder specification, and the pressure in die cavity acts on column by side form, be out of shape for preventing column, patrix is except being connected with mandrel plate, also be provided with that connect with column top, that size is almost equal with lower bolster cope match-plate pattern, the assembly of whole set of die is many, complex structure.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of low-pressure casting mould for wheel hub, and the assembly that can solve existing low-pressure casting mould for wheel hub is many, complex structure and withstand voltage be by the problem of oil cylinder restriction.
The utility model is achieved through the following technical solutions:
A kind of low-pressure casting mould for wheel hub, form the counterdie of wheel hub casting mold cavity, side form and patrix after comprising combination, described side form is the frustroconical that one end is large, the other end is little, and described side form is provided with locked mode cover.
Further improvement of the utility model scheme is, described side form outer wall tapering is 8 ° ~ 12 °.
Further improvement of the utility model scheme is, described locked mode cover internal diameter is between the large end external diameter of side form and small end external diameter, and its inwall is provided with the tapering identical with side form outer wall.
Further improvement of the utility model scheme is, described side form is docked by the curved portions that four sections of openings are relative and forms, and described counterdie is arranged on lower bolster, and the curved portions lower slide of composition side form is connected to lower bolster.
Further improvement of the utility model scheme is, described curved portions lower end and lower bolster surface are respectively equipped with the slide block and chute that cooperatively interact.
Further improvement of the utility model scheme is, the axial length of described locked mode cover is 1/3 ~ 1/2 of side form height.
Further improvement of the utility model scheme is, described patrix upper end is connected with mandrel plate.
The utility model advantage is compared with prior art:
One, side form outer wall is frustroconical, is locked, eliminate column, cope match-plate pattern by the locked mode cover being connected to its outer wall, reduces the assembly of mould, simplifies mould structure;
Two, compare the matched moulds of existing low pressure casting, the demoulding needs to consider many factors, operation professional requires high, simplifies matched moulds, demoulding step, achieves a kind of foolproof operation;
Three, the restriction of oil cylinder specification is overcome, effective raising die cavity withstand voltage, thus the crystallization and the density that improve product, the product strength waiting heavy aluminium water to produce is better than existing product, aluminium water weight needed for the product of same intensity reduces about 10%, effectively improves the competitiveness of product in market.

Detailed description of the invention
A kind of low-pressure casting mould for wheel hub as depicted in figs. 1 and 2, the counterdie 2 of wheel hub casting mold cavity, side form and patrix 4 is formed after comprising combination, described patrix 4 upper end is connected with mandrel plate 5, described counterdie 2 is arranged on lower bolster 1, described side form is docked by the curved portions 3 that four sections of openings are relative and forms, curved portions 3 lower end and lower bolster 1 surface of composition side form are respectively equipped with the slide block and chute that cooperatively interact, make curved portions 3 be slidably connected to lower bolster 1; Described side form outer wall to be one end is large, the other end is little tapering the be frustroconical of 8 ° ~ 12 °, described side form outer wall is connected with the annular locked mode cover 6 that axial length is side form height 1/3 ~ 1/2, described locked mode overlaps 6 internal diameters between the large end external diameter and small end external diameter of side form outer wall, and its inwall is provided with the tapering identical with side form outer wall.
Adopt cross cylinder to promote curved portions 3 to dock, then fallen by vertical hydraulic oil cylinder driving locked mode cover 6 and be enclosed within side form outer wall and realize locking, then patrix 4 moves down and realizes matched moulds; Due in die cavity to the active force of a side form part for overcoming the frictional force between locked mode cover 6 and side form, another part directly acts on locked mode cover 6, and therefore the specification requirement of cross cylinder and vertical oil cylinder all significantly reduces; First rise patrix 4 and locked mode cover 6 successively during the demoulding, then open side form.
