Description
Technical Field
The utility model relates to a numerical control processing technology field, more specifically say, relate to a template for casting high-accuracy numerical control machining center workstation.
Background
The chilling block is a chilling object arranged in the cavity, the surface of the cavity and the interior of the casting mold for accelerating the local cooling speed of the casting. The chilling block is matched with a pouring system and a riser system for use, and the solidification sequence of the casting is controlled to obtain a qualified casting. The cold iron is divided into inner cold iron and outer cold iron.
The function of the chill is to reduce the size of the riser and improve the process yield. Practice shows that the steel casting process yield can reach more than 70% by reasonably using a chill and a heat-insulating riser technology; the chill is placed at the proper position of the casting, so that the feeding channel can be improved. The internal quality grade of the casting can be improved, and a high-quality casting is provided; the feeding distance of the riser can be increased by using a chill in cooperation with a riser system: when designing the chiller, the thought is released, and the effective effects of the chiller on the aspects of patching, inclination, continuity and the like of the casting are comprehensively considered; the local thermal stress is eliminated, and the cracks are prevented. For large steel castings, chromite sand or zircon sand with good chilling effect should be used between the chills, so that the possibility of hot cracking can be further prevented; in the lost foam casting, chill can be used exactly as in the conventional casting method. The external chill can be released when the heat-conducting silicone grease is used; the internal chill can be embedded or bonded in the casting mould during moulding, or can be extended to the outside of the mould and fixed in the sand mould. The placing principle of the internal and external chills for lost foam casting is similar to the type and specification of chills in common casting; the cold iron is placed to accelerate the solidification speed of the casting, refine the grain structure and improve the mechanical property of the casting.
However, the existing chiller for casting the numerical control workbench has some defects in practical use, for example, the contact area between a template for casting and the chiller is limited, so that the heat transfer speed is slow, meanwhile, the chiller can only carry out natural heat dissipation, and the cooling effect is poor. In view of the above, we propose a template for casting a high-precision numerical control machining center worktable, especially a heat dissipation structure of a casting template.
