LY type anti-flat five-tool changer precoated sand mold

Abstract

The invention provides an LY type anti-flat five-tool changer precoated sand mold. Four symmetric five-sided protrusions are arranged in each of an upper mold cavity and a lower mold cavity, one edgepins of every two adjacent protrusions arranged up and down are connected, column bodies are also arranged at the centers of the edge pins of the protrusions, sprue mounting positions are also arranged between the protrusions, a pouring gate is a four-joint pouring gate, and each joint of the pouring gate is in contact with the two edge pins close to the insides of the corresponding protrusion. The LY type anti-flat five-tool changer precoated sand mold has the beneficial effect that through the arrangement of the reasonable cavities, the reasonable pouring gate and the reasonable sand shooting opening, the yield of a sand shell can be increased, and the yield of an uncoupling lever bracket during molten iron casting is improved.

Description

technical field [0001] The invention relates to the field of hot core box manufacturing, in particular to an LY type reverse-flat five-knife magazine-coated sand mold. Background technique [0002] The tool magazine system is a device that provides the tool storage and tool change requirements required in the automated machining process. Its automatic tool change mechanism and the tool magazine can store multiple tools. With the control of computer programs, various processing requirements can be completed, such as milling, drilling, boring, tapping, etc., which greatly shortens the processing time and reduces production costs. This is the biggest feature of the tool magazine system. [0003] At present, most of the LY-type anti-flat five-tool magazines are produced in the form of casting, but the sand shell mold currently used has a lot of defects in the design, such as slow sand shooting speed, low pass rate, uneven thickness of the sand shell, etc. When subsequent castin...
