Abstract
The utility model discloses a mold inclined core-pulling mechanism which comprises a hydraulic oil cylinder, a hydraulic oil cylinder telescopic arm, a core-pulling connection piece and a mold core, the hydraulic oil cylinder, the hydraulic oil cylinder telescopic arm and the core-pulling connection piece are arranged on an upper mold along a horizontal direction, the mold core is connected with the lower portion of the core-pulling connection piece along an inclined direction, core-pulling battens which are vertically fixed on a lower mold are arranged on two sides of the core-pulling connection piece, sliding slots which have the same inclined direction with the mold core are arranged on one sides of the core-pulling battens, the sides of the core-pulling battens are adjacent to the core-pulling connection piece, and protruding portions which are in sliding fit with the sliding slots are arranged on two sides of the core-pulling connection piece. According to the mold inclined core-pulling mechanism, inclined core-pulling can be performed while mold opening is performed, time for mold opening is reduced, products can be free from deforming due to secondary stressing of core-pulling and mold opening, and molding precision of the products is improved. Besides, the mold opening speeds and the contraction speeds of the hydraulic oil cylinder can be adjusted to achieve the adjustment of inclined degrees of core-pulling, and the mold inclined core-pulling mechanism is capable of adapting to mold core-pulling with different inclined degrees.
Description
Technical field
The utility model relates to a kind of die casting core-pulling mechanism, the oblique core-pulling mechanism of especially a kind of die casting.
Background technology
Compression casting is called for short die casting, is that a kind of alloy liquid with fusing is poured into and pressed indoorly, with the die cavity of high speed filling steel die, and alloy liquid is solidified under pressure and forms the casting method of foundry goods.Generally need during die-casting process to adopt a quiet mould and a dynamic model, form workpiece cavity behind quiet mould and the dynamic model matched moulds, under pressure molten metal is pressed in the workpiece shape chamber then, promptly obtain the workpiece of moulding after the cooling.
Extrusion process need be provided with a core that is complementary with the hole producing some when having the workpiece in hole in mold cavity, core links to each other with core-pulling mechanism, and when die sinking, employing core-pulling mechanism extraction core promptly stays hole in shaping workpiece.When hole in the product is the hole of oblique setting; Need to adopt oblique core-pulling mechanism; Existing oblique core-pulling mechanism comprises hydraulic jack, the hydraulic jack telescopic arm that is linked in sequence successively, loose core connector and core, and its whole each member of oblique core-pulling mechanism all is oblique layouts; Directly the edge is oblique with after the core extraction for the hydraulic jack telescopic arm when loosing core, and carries out die sinking again.This existing oblique core-pulling mechanism is loosed core and die sinking is divided into two steps and carries out, and die sinking is consuming time longer, simultaneously easily because of product successively twice stressed, cause phenomenons such as product deformation and failure easily, be unfavorable for improving the formed product precision.
The utility model content
To the deficiency of above-mentioned prior art, the technical problem that the utility model will solve is: how to provide a kind of and in die sinking, loose core, reduce the die sinking time, improve the oblique core-pulling mechanism of mould of formed product precision.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
The oblique core-pulling mechanism of a kind of mould; Comprise hydraulic jack, the hydraulic jack telescopic arm that is linked in sequence successively, loose core connector and core; It is characterized in that; Said hydraulic jack, hydraulic jack telescopic arm and the equal along continuous straight runs of the connector of loosing core are arranged on the patrix, and said core is along the oblique connector below of loosing core that is connected, and the said connector both sides of loosing core also have the press strip of loosing core that vertically is fixedly installed on the counterdie; A side adjacent with the connector of loosing core has and the consistent chute of core incline direction on the said press strip of loosing core, and the said connector both sides of loosing core have the convexity that is slidingly fitted in the chute.
When the utility model uses, when die sinking, up move with patrix, hydraulic jack drives the hydraulic jack telescopic arm synchronously to after-contraction, makes the connector of loosing core loose core relatively and slide to oblique upper in the chute of press strip, so with core along oblique extraction.
In sum, the utility model can carry out oblique loosing core in die sinking, reduced the die sinking time, and product need not to cause being out of shape with the die sinking secondary loading through loosing core simultaneously, has improved the formed product precision.In addition, the utility model can be through regulating opening speed and hydraulic jack contraction speed, and so that the gradient of loosing core is regulated, the core that can adapt to different gradients is loosed core.
Description of drawings
Structural representation when Fig. 1 is the utility model practical implementation.
The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing the utility model is done further to specify.
During practical implementation; As shown in Figure 1; The oblique core-pulling mechanism of a kind of mould comprises hydraulic jack 1, the hydraulic jack telescopic arm 2 that is linked in sequence successively, loose core connector 3 and core 4, and said hydraulic jack 1, hydraulic jack telescopic arm 2 and the connector 3 equal along continuous straight runs of loosing core are arranged on the patrix; Said core 4 is along oblique connector 3 belows of loosing core that are connected; Said connector 3 both sides of loosing core also have the press strip 5 of loosing core that vertically is fixedly installed on the counterdie 7, have and the consistent chute 6 of core 4 incline directions with the connector 3 adjacent sides of loosing core on the said press strip 5 of loosing core, and said connector 3 both sides of loosing core have the convexity that is slidingly fitted in the chute 6.
During practical implementation, the sub-assembly that the said connector 3 of loosing core is made up of the members such as seat, fuse pressing plate, the guide block of loosing core of loosing core.
