Abstract

The utility model relates to a sintering-preventing aluminium scrap entrance-preventing guide pillar structure of a die-casting mould. The structure comprises a guide pillar (1) and a guide sleeve (2), wherein the guide sleeve (2) is vertically mounted in a guide pillar hole of a lower mould board, the guide pillar (1) is vertically mounted in a guide pillar hole of an upper mould board, the lower end of the guide pillar (1) is inserted downwards into the guide sleeve (2), and the lower half of the guide pillar (1) is a flat column (11). The sintering-preventing aluminium scrap entrance-preventing guide pillar structure is simple in structure, and with the adoption of the flat column structure and coordination between the flat column and a round column, metal scraps cannot enter into the gap between the guide pillar and the guide sleeve, thereby avoiding influences caused by verticality changes of the guide pillar, saving materials, and reducing costs.

Description

A kind of anti-sintering is prevented the into compression mod guide pillar structure of aluminium

Technical field

The utility model relates to the mold component field, and particularly a kind of anti-sintering is prevented the into compression mod guide pillar structure of aluminium.

Background technology

Guide pillar is parts necessary in the die casting, mainly plays the guide effect of moving between the upper die and lower die, and in order to prevent that metal fragment enters between the guide pillars and bushes in the guiding process, the quality of fit between the guide pillars and bushes requires very high.Present guide pillar all is columniform, in use, because the work under bad environment of die casting, and the mould temperature is very high, cause the perpendicularity of guide pillar to change easily, pitch enlargement between the guide pillars and bushes, friction stroke iron gold-plating causes stuck in the die casting circulation is produced, particularly in the large die-casting mould more than 15 tons, in case stuck, the dismounting of mould will be very difficult, cause serious economic loss.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of anti-sintering and prevents the into compression mod guide pillar structure of aluminium, simple in structure, adopt flat rod structure, the cooperation of flat post and cylinder, neither can allow metal fragment enter between the guide pillars and bushes, and the influence of having avoided the guide pillar perpendicularity to change, also saved material, reduced cost.

The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of anti-sintering to prevent the into compression mod guide pillar structure of aluminium, comprise guide pillars and bushes, described guide pin bushing vertically is installed in the guide pillar hole of lower bolster, described guide pillar vertically is installed in the guide pillar hole of cope match-plate pattern, the lower ends downward of described guide pillar is inserted in the guide pin bushing, it is characterized in that the Lower Half of described guide pillar is flat post.

The root of described flat post is 25mm～35mm from the distance of the transversal centerline of guide pillar.

The width of described flat post is 70%～80% of guide pillar top body diameter length.

Evenly be furnished with some translots on the outer arc face of described flat post from top to bottom.

Beneficial effect

The utility model relates to a kind of anti-sintering and prevents the into compression mod guide pillar structure of aluminium, and is simple in structure, adopts flat rod structure, the cooperation of flat post and cylinder neither can allow metal fragment enter between the guide pillars and bushes, and the influence of having avoided the guide pillar perpendicularity to change, also save material, reduced cost.
