Accompanying drawing explanation
Fig. 1 is the exploded view of microdiecast mould in embodiment of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, what following examples provided the utility model by reference to the accompanying drawings is specifically addressed for the microdiecast mould processing engine shock absorber cavity.
As shown in Figure 1, what the present embodiment provided comprises for the microdiecast mould processing engine shock absorber cavity: cover half 1, dynamic model 2 and sliding block core-pulling mechanism 3, and, for the ease of the structure of this microdiecast mould of clear display, in FIG, dynamic model 2 is forward placement, and cover half 1 is oppositely place.Concrete, cover half 1 lower surface offers cover half die cavity 11, and dynamic model 2 upper surface offers dynamic model die cavity 21, and sliding block core-pulling mechanism 3 has slider core 31 and hydraulic cylinder 32.Wherein, cover half die cavity 11, dynamic model die cavity 21 and slider core 31 are combined to form the die casting die cavity matched with engine shock absorber cavity.
In the present embodiment, cover half 1 and dynamic model 2 drive vertical folding by die casting machine, wherein, offer the die-casting melting cup 12 for high pressure injection moulding in cover half die cavity 11, thus solution is filled in die casting die cavity.Hydraulic cylinder 32 is laterally arranged on dynamic model 2 can drive slider core 31 horizontal sliding.Before cover half 1 and the 2-in-1 mould of dynamic model, first by sliding block core-pulling mechanism 3 side direction matched moulds; Before cover half 1 and dynamic model 2 parting, first loosed core by sliding block core-pulling mechanism 3 undercut.
Concrete, in order to realize the accurate location of slider core 31 and cover half die cavity 11 in press casting procedure, and in order to prevent accurate slider core 31 from affecting precision because slippage continually produces wearing and tearing two, in the present embodiment, slider core 31 is provided with two the first wear-resisting locating pieces 33 on the sidewall towards hydraulic cylinder 32.Accordingly, as preferred technical scheme, two the first wear-resisting locating pieces 33 are divided into the both sides of hydraulic cylinder 32.The madial wall of cover half die cavity 11 is provided with two difference just to the second wear-resisting locating piece 13 of the first wear-resisting locating piece 33.
In addition, in order to realize the smooth demoulding of engine shock absorber cavity after die cast, dynamic model 2 is provided with liftout attachment 22 in dynamic model die cavity 21 position, thus engine shock absorber cavity is ejected dynamic model die cavity 21.
In order to the piston rod stroke of accurate hydraulic control cylinder 32, and then guarantee the exact position of slider core 31 when matched moulds, dynamic model 2 is provided with hydraulic cylinder travel sensor 34 in the side of hydraulic cylinder 32.
Four bights of cover half 1 lower surface arrange a guide pillar 14 respectively, and the position that dynamic model 2 upper surface is corresponding to every root guide pillar 14 arranges a guide pin bushing 23 respectively.Can guarantee that the matched moulds direction between dynamic model 2 and cover half 1 is accurate by the cooperation of guide pillar 14 and guide pin bushing 23.
When the microdiecast die casting engine shock absorber cavity using the present embodiment to provide, first cover half 1 and dynamic model 2 are respectively installed on outside die casting equipment (as die casting machine); Make dynamic model die cavity 21, cover half die cavity 11 and slider core 31 under the effect of matched moulds, close the die casting die cavity being formed and match with engine shock absorber cavity; Smelting aluminium alloy 630-670 aluminium liquid importing die-casting melting cup 12 li is also carried out high-pressure injection by adjustment die-casting technological parameter, makes aluminium liquid fill full dynamic pressure mould cavity; After engine shock absorber cavity die cast, dynamic model 2 moves down and is separated with cover half 1, drives slider core 31 to be separated with cover half 1 by hydraulic cylinder 32; When hydraulic cylinder travel sensor 34 triggers after hydraulic cylinder 32 quits work, outwards ejected by the engine shock absorber cavity of liftout attachment 22 by die cast.
The microdiecast mould for processing engine shock absorber cavity that the present embodiment provides, on the basis that fixed half and moving half matches, by arranging sliding block core-pulling mechanism, and cover half die cavity, dynamic model die cavity and slider core be combined to form the die casting die cavity matched with engine shock absorber cavity there is die casting after engine shock absorber cavity there is higher formed precision and structural strength, for complex-shaped engine shock absorber cavity, be convenient to the demoulding, enhance productivity, and be conducive to the formed precision and the structural strength that improve engine shock absorber cavity.
Certainly, the structure be not merely defined in for the microdiecast mould processing engine shock absorber cavity in the present embodiment involved by the utility model, any equivalent modifications that the utility model is carried out and substituting also all in category of the present utility model.
