Abstract
The invention discloses an aluminium wheel spinning mould ejector. The opening position and the angle of the conical surface of a low die ejector 4 are changed, the middle position of a spoke in the prior art is changed to the circular arc on the joint of the spoke and a rim, and the angle is changed to 45 degrees from 50 degrees. An anti-rotation groove is milled on the faying surface of a spoke back cavity, the connection position of the low die ejector and a guiding copper bush is changed, and an upper die ejector is decomposed into a new upper die ejector 8 and a guidepost 6. The upper die ejector 8 is connected with an upper die bolt, and the guidepost 6 is connected with the upper die bolt to perform the action of guiding. A disc spring 7 is arranged between the new upper die ejector 8 and an upper die 1.
Description
Technical field
The present invention relates to a kind of ejector of spinning mould, relate in particular to the upper and lower mould ejector that aluminum-alloy wheel spinning mould is revolved in a kind of casting.
Background technology
Lifting Device is one of vitals in the spinning mould, directly influences the forming technology of rim for automobile wheel spinning.As shown in Figure 1, the Lifting Device of prior art is made up of patrix ejector and counterdie ejector.
The structure of existing counterdie ejector makes it skid with the wheel generation in spinning process easily, and the phenomenon that wheel throws switch takes place, and makes wheel spoke back of the body chamber scratch, produce aluminium and considers to be worth doing, even cause the counterdie ejector to glue aluminium.The aluminium bits that produce enter in the gap of counterdie and counterdie ejector easily, make normally return of counterdie ejector, and during spinning, wheel spoke also can produce gross distortion, can not guarantee the dimensional requirement of spinning blank again.Equally, the sticking aluminium of counterdie ejector can make itself and spoke back of the body chamber applying degree descend, and the acceleration blank skids and is out of shape.
The structure of existing patrix ejector easily makes patrix ejector and wheel center boss produce serious rigid shock when binder; During the material returned, wheel can not effectively separate with ejector, causes the wheel distortion.
The existing design of the guiding copper sheathing that links to each other with the counterdie ejector can make the wheel flange scratch equally.
Summary of the invention
The objective of the invention is to provide a kind of improved ejector.It can solve in the mould pressing process wheel effectively and throw switch and be out of shape, and alleviates the rigid shock of mould to wheel hub.Have simultaneously simple in structure, be convenient to make, characteristics that precision can satisfy dimensional requirement.
Technical scheme of the present invention is: the aperture position and the angle of the change counterdie ejector conical surface, be changed to the circular arc place of spoke and wheel rim junction by the spoke middle part of prior art, and its angle changes to 45 ° by 50 °.
Carry on the back chamber binding face place milling anti-rotation groove with spoke, changing the link position of counterdie ejector and guiding copper sheathing;
The patrix ejector is resolved into new patrix ejector, lead.Described new patrix ejector is connected with the patrix bolt; Lead is connected with the patrix bolt, play the guiding role.
Between new patrix ejector and the patrix by the dish spring is arranged.
Described new counterdie ejector substitutes the counterdie ejector, and described new guiding copper sheathing substitutes the guiding copper sheathing.Described new patrix ejector and lead substitute the patrix ejector.
Described new counterdie ejector and new guiding copper sheathing link together by pin and counterdie, can guarantee the free return of counterdie ejector; Simultaneously solve blank again and produced relative slip when rotated with counterdie, occur throwing switch, improved the distortion at blank spoke back of the body chamber and flange place.
Described new patrix ejector, lead, dish spring can be made standard component, exchange between the mould of difference wheel type and use.
The present invention passes through to change the structure of upper and lower mould ejector, and is provided with anti-rotation groove, increases the dish spring, has solved the matching problem of wheel and mould preferably, has improved counterdie ejector return difficulty in the prior art, the difficult problem of wheel rotary pressure deformation.

The specific embodiment
Technical scheme of the present invention is:
The aperture position and the angle of change counterdie ejector 4 conical surfaces are changed to the circular arc place of spoke and wheel rim junction by the spoke middle part of prior art, and its angle changes to 45 ° by 50 °.
Carry on the back chamber binding face place milling anti-rotation groove with spoke, changing the link position of counterdie ejector and guiding copper sheathing;
The patrix ejector is resolved into new patrix ejector 8, lead 6.Described new patrix ejector 8 is connected with the patrix bolt; Lead 6 is connected with the patrix bolt, play the guiding role.
Between new patrix ejector 8 and the patrix 1 by dish spring 7 is arranged.
Described new counterdie ejector 10 substitutes counterdie ejector 4, as Fig. 2, shown in Figure 4.Described new guiding copper sheathing 9 substitutes guiding copper sheathing 3.Described new patrix ejector 8 and lead 6 substitute patrix ejector 2.
Described new counterdie ejector 10 and new guiding copper sheathing 9 link together by pin and counterdie 5, can guarantee the free return of counterdie ejector; Simultaneously solve blank again and produced relative slip when rotated with counterdie, occur throwing switch, improved the distortion at blank spoke back of the body chamber and flange place.
Described new patrix ejector 8 is connected with patrix 1 bolt, and dish spring 7 is arranged in the middle of both; Lead is connected with patrix 1 bolt, play the guiding role.Can alleviate the rigid shock of existing mold to blank.
The connected mode that the upper and lower mould ejector of spinning mould of the present invention provides is not limited to the described content of the content of the present invention and the specific embodiment, and content inspires and other connected modes of acquisition according to the present invention, all falls into protection scope of the present invention.
