A die-casting die for a shock absorber inner core comprises a moving die (1), a positioning column (2), a fixed die (6), a first side sliding block (3), a second side sliding block (13) and a guide column (14), wherein the two side sliding blocks are arranged on the moving die (1). The die-casting die is characterized in that the moving die (1) and the fixed die (6) are assembled under the effect of the positioning column (2) and the guide column (14), and molten metal is poured to two shock absorber inner core mold cavities (5) through pouring gates (11), reaches all parts of the mold cavities and is subjected to pressure maintaining and die-cast formation to form the shock absorber inner core. The shock absorber inner core is formed by pouring the molten metal to the two mold cavities in one step, so that the die-casting production efficiency is greatly improved and the production cost of parts is reduced; the die is simple in structure, difficult to damage and long in service life, solves the problems of casting crack, deformation and the like in a conventional production process, and is capable of producing a shock absorber inner core casting which fully meets the requirements and is good in surface quality.

Description

A kind of damper inner core die casting

Technical field

The utility model relates to a kind of metal die-casting mold, especially relates to a kind of damper inner core die casting.

Background technology

The damper inner core is a strength member on automobile.This kind damper core arrangement complexity, wall is thin, the general die casting mode that adopts is produced, but in foundry production, easily have pore, be not fully filled, the defects such as surface quality is poor, cracking, distortion, and and then cause production efficiency low, for addressing these problems, need design shock damper inner core die casting.

Summary of the invention

For above deficiency, the purpose of this utility model is to provide a kind of damper inner core die casting, in mould, to be provided with two inner core die cavities, one-time cast-forming, solved in the press casting procedure, be prone to pore, be not fully filled, the defects such as surface quality is poor, cracking, distortion, production efficiency is greatly improved.

The technical solution of the utility model is achieved in the following ways: a kind of damper inner core die casting, comprise dynamic model, locating dowel, cover half, the first side slide, the second side slide and guide pillar, described two side slides are located on dynamic model, on dynamic model, also be provided with dynamic mould core, dynamic model push-rod hole and dynamic model slag trap, cover half is provided with cover half cooling water channel, fixed mold, running channel and cover half slag trap, and the space that the profile of dynamic model, cover half and two side slides surrounds is two damper inner core die cavities; It is characterized in that: described dynamic model and cover half are after matched moulds under the effect of directed post and guide pillar, and molten metal is poured into a mould to two damper inner core die cavities through running channel, and arrive each position of die cavity, and pressurize, die cast are the damper inner core.

Described running channel is located at the cast gate place of cover half, is divided into two, leads to respectively two die cavities of mould.

Described dynamic model slag trap and cover half slag trap form the overflowing system of mould, be looped around fixed mold and dynamic mould core around.

The utility model, adopt two die cavity one-time cast-formings, and the production efficiency of die casting is greatly improved, and reduces simultaneously the production cost of part; This mould structure is simple, and not fragile, the life-span is long, has solved the problems such as the foundry goods cracking that exists in production process in the past, distortion, can produce the damper inner core foundry goods met the demands fully, and surface quality of continuous castings is good.

In figure: 1 dynamic model; 2 locating dowels; 3 first side slides; 4 cover half cooling water channels; 5 die cavities; 6 cover half; 7 dynamic mould cores; 8 dynamic model push-rod holes; 9 dynamic model slag traps; 10 fixed molds; 11 running channels; 12 cover half slag traps; 13 second side slides; 14 guide pillars; 15 cast gates.

The specific embodiment

By Fig. 1, Fig. 2, known, a kind of damper inner core die casting, comprise dynamic model 1, locating dowel 2, cover half 6, guide pillar, the first side slide 3 and the second side slide 13, described two side slides are located on dynamic model 1, and the space that the profile of dynamic model 1, cover half 2 and two side slides surrounds is two damper inner core die cavities 5; Described dynamic model 1 and cover half 6 by directed post 2 guiding matched moulds after, molten metal pour into a mould to two damper inner core die cavities through running channel 11, and each position of arrival die cavity, pressurize, die cast are the damper inner core.Described two locating dowels 2 play the role of positioning, and because damper inner core size is little, precision is high, during matched moulds, two side slides must just can cast out high-quality damper inner core by complete matching.During mold work, pass into cooling water so that die casting is in thermal equilibrium state by cover half cooling water channel 4, and by the gap exhaust between two side slides and cover half 6 and dynamic model 1.

By Fig. 3, being known, is the dynamic model structural representation.Dynamic model 1 is provided with double acting die core 7, dynamic model push-rod hole 8 and dynamic model slag trap 9, and dynamic model 1 and cover half 6 are by two directed matched moulds of directed post 2.Described dynamic model slag trap 9 and cover half slag trap 12 forms the overflowing system of moulds, be looped around fixed mold and dynamic mould core around.

By Fig. 4, being known, is the fixed mould structure schematic diagram.Cover half 2 is provided with cover half cooling water channel 4, fixed mold 10, running channel 11 and cover half slag trap 12, and running channel 11 is located at cast gate 15 places of cover half, is divided into two, leads to respectively the damper inner core die cavity 5 of mould.Running channel 11, through the emulation of Procast professional software, guarantees that molten metal can not produce eddy current bag gas and oxide inclusion defect after running channel enters die cavity.The cover half cooling water channel 4 of offering on cover half, can extend die life on the one hand, prevents the mould aging cracking, can guarantee that on the other hand cast temperature is constant.During mold work, pass through the gap exhaust between two side slides and fixed half and moving half, in damper inner core die cavity 5, original air just can be discharged easily after being pressed into motlten metal, this has just reduced the flow resistance of motlten metal, increased the mobility of motlten metal, thereby make motlten metal can arrive smoothly each position of damper inner core die cavity, the product of die cast is not easy to occur defect thus, has improved the quality of product.Dynamic model is provided with dynamic model push-rod hole 8, so that die sinking rear push-rod pushing out casting.

Mold work process: during the mould matched moulds, under the guiding and positioning action of guide pillar 14 and locating dowel 2, Clamping System drives dynamic model 1 and moves to cover half 6 directions, and two side slides move to operating position under the guide pillar effect, simultaneously under the effect of locating dowel 2, two side slides and cover half, dynamic model are quick and precisely located, and make the mould closure, and provide enough clamp force locking dies by Clamping System.Then start die casting, by die casting machine work hand, aluminium liquid is poured into and pressed in chamber and exert pressure and enter mould by sprue bush through injection mechanism, after pressurize a period of time, Clamping System drives dynamic model 1 to away from cover half 6 directions, moving, two side slides separate under the guide pillar effect simultaneously, then push rod stretches out in dynamic model push-rod hole 8, by damper inner core foundry goods from mould, releasing.During matched moulds, push rod resets, and mould is prepared die casting next time.
