Problems solved by technology

[0004] The object of the present invention is to provide a casting system for the bed of a large-scale gantry machining center, which solves the problems of the traditional bed casting system by adopting the bottom injection type short-range liquid introduction pouring system, the integral movable block and the use of hooks for clay core matching. Most of the runners are long, and the process of introducing liquid is slow during pouring, which affects the pouring efficiency of the product

Abstract

The invention discloses a gating system for casting a large sized gantry machining center bed. The gating system comprises a whole mold, a whole loose piece and a lifting hook, wherein the exterior ofthe whole mold is provided with a cross gate; the cross gate is provided with a sprue in a penetration manner; the top of the whole mold is provided with a lifting core; the whole mold comprises a core pulling mold and an external mold local loose piece; the bottom of the core pulling mold is provided with a core head; the middle of an inner cavity of the whole mold is provided with first core chambers; an inner cavity of the first core chamber is provided with a first loam core; two sides of the first core chambers are provided with second core chambers; inner cavities of the second core chambers are provided with second loam cores; two sides of the second core chambers are provided with third core chambers; inner cavities of the third core chambers are provided with third loam cores; two sides of the third core chambers are provided with fourth core chambers. According to the gating system, the short-distance liquid guidance is carried out through adopting the sprue of a machine tool bed casting; the liquid guidance time is greatly decreased when the body is subjected to gating, and the gating efficiency and the gating quality of a product are improved.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a casting system for a bed of a large-scale gantry machining center. Background technique [0002] The CNC gantry milling machine is an important functional accessory for the design of heavy-duty CNC bed and other types of machine tools. It is independent of the machine tool body and completes the linear feed function during the machining process of the CNC machine tool. At the same time, it can realize some auxiliary functions of the machine tool, ensure machining accuracy, improve production efficiency and reduce labor intensity. Therefore, the rigidity and dynamic performance of the bed have a great influence on the overall machining performance of the machine tool matched with it, including machining accuracy and machining efficiency. However, the runners of the traditional bed casting system are mostly long, and the liquid introduction process is slow during pouring, which...
