Abstract

The invention relates to a damper inner core die-casting die which comprises a moving die (1), a positioning pillar (2), a fixed die (6), a first side sliding block (3), a second side sliding block (13) and a guiding pillar (14). Two side sliding blocks are arranged on the moving die (1). The damper inner core die-casting die is characterized in that after the moving die (1) and the fixed die (6) are combined under the action of the positioning pillar (2) and the guiding pillar (14), metal liquid is poured into two damper inner core type cavities (5) through a pouring channel (11) and reaches all portions of the cavities. A damper inner core is formed after pressure maintaining and die-cast formation are performed. According to the damper inner core die-casting die, pouring formation is carried out at a time in two cavities, so that the production efficiency of die-casting is greatly improved and meanwhile, production cost of parts is reduced. The die-casting die is simple in structure, not prone to damage, long in service life, capable of producing damper inner core casts which fully meet the requirements as the problems of cracking and deforming of a cast and the like in a previous production process are solved, and good in quality of surfaces of the casts.

Description

A kind of damper inner core die casting

Technical field

The present invention relates to a kind of die cast metal mould, especially relate to a kind of damper inner core die casting.

Background technology

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

Summary of the invention

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

Technical scheme of the present invention realizes in the following manner: a kind of damper inner core die casting, comprise dynamic model, reference column, cover half, first side slide, second side slide and guide pillar, described two side slides are located on the dynamic model, also be provided with dynamic mould core, dynamic model push-rod hole and dynamic model slag trap on the dynamic model, cover half is provided with cover half cooling water channel, cover half core, 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 behind 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 two die cavities of mould respectively.

The row that described dynamic model slag trap and cover half slag trap the are formed mould system of overflowing, be looped around cover half core and dynamic mould core around.

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

Among the figure: 1 dynamic model; 2 reference columns; 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 cover half cores; 11 running channels; 12 cover half slag traps; 13 second side slides; 14 guide pillars; 15 cast gates.

The specific embodiment

Known by Fig. 1, Fig. 2, a kind of damper inner core die casting, comprise dynamic model 1, reference column 2, cover half 6, guide pillar, first side slide 3 and second side slide 13, described two side slides are located on the 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 reference columns 2 play the role of positioning, and are little because of damper inner core size, precision is high, and two side slides must just can cast out high-quality damper inner core by complete matching during matched moulds.During mold work, feed 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 the dynamic model 1.

Being known by Fig. 3, 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 post 2 directed matched moulds.The row that described dynamic model slag trap 9 and cover half slag trap 12 the formed moulds system of overflowing, be looped around cover half core and dynamic mould core around.

Being known by Fig. 4, is the cover half structural representation.Cover half 2 is provided with cover half cooling water channel 4, cover half core 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 the damper inner core die cavity 5 of mould respectively.Running channel 11 guarantees that through the emulation of Procast professional software molten metal can not produce eddy current bag gas and oxide inclusion defective after running channel enters die cavity.The cover half cooling water channel of offering on the cover half 4 can prolong die life on the one hand, prevents the mould aging cracking, can guarantee that on the other hand cast temperature is constant.Pass through the gap exhaust between two side slides and the fixed half and moving half during mold work, original air just can be discharged after being pressed into motlten metal easily in the damper inner core die cavity 5, this has just reduced the molten metal flow resistance, increased molten metal flow, thereby make motlten metal can arrive each position of damper inner core die cavity smoothly, the product of die cast is not easy to occur defective thus, has improved the quality of product.Dynamic model is provided with dynamic model push-rod hole 8, so that the die sinking rear push-rod is released foundry goods.

Mold work process: during the mould matched moulds, under the guiding and positioning action of guide pillar 14 and reference column 2, the matched moulds system drives dynamic model 1 and moves to cover half 6 directions, and two side slides move to the operating position under the guide pillar effect, simultaneously under the effect of reference column 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 moulds by the matched moulds system.Begin die casting then, by die casting machine work hand aluminium liquid is poured into pressing exerts pressure in the chamber and through injection mechanism enters mould by sprue bush, after pressurize a period of time, the matched moulds system drives dynamic model 1 to moving away from cover half 6 directions, two side slides separate under the guide pillar effect simultaneously, push rod is released damper inner core foundry goods by stretching out in the dynamic model push-rod hole 8 from mould then.During matched moulds, push rod resets, and mould is prepared die casting next time.
