Introduction

GB/T 46639 covers casting machinery used in casting production.

Casting, as a metal heat treatment process that involves filling a mold with molten metal and allowing it to solidify to obtain parts or part blanks, has a long history.

History, and its technology is constantly developing and changing. Depending on the mold used, or the method of filling or solidification of the molten metal, it varies.

Depending on the method, there are many different casting processes, such as sand casting, investment casting, lost foam casting, die casting, low-pressure casting, and metal mold casting.

Force casting and centrifugal casting, etc.

GB/T 46639, as the fundamental standard for casting machinery, defines each concept applicable to the general application of casting machinery.

The scope covers various casting equipment for different casting methods and different production process stages.

GB/T 46639 is proposed to be divided into the following six parts.

---Part 1: Fundamentals. The purpose is to define the basic terminology and definitions of casting machinery.

---Part 2: Molding, Core-Making Machines and Other Non-Permanent Casting Equipment. The purpose is to define molding machines, core-making machines, and other non-permanent casting equipment.

Terminology and definitions for long-form casting equipment.

---Part 3: Die Casting Machines and Other Permanent Casting Equipment. The purpose is to define the technical specifications of die casting machines and other permanent casting equipment.

Language and definition.

---Part 4: Shot blasting machines and other casting cleaning equipment. The purpose is to define shot blasting machines and other casting cleaning equipment.

Equipment terminology and definitions.

---Part 5: Cupola, Casting Equipment and Ladle. The purpose is to define the terminology and definitions for cupola, casting equipment and ladle.

---Part 6: Other. The purpose is to define the casting machinery-related terms and definitions not covered in Parts 1 through 5.

This document is Part 3 of GB/T 46639, defining the terms and definitions for die casting machines and other permanent casting equipment, including various...

Structural features and functions of die casting machines, squeeze casting machines, low-pressure die casting machines, centrifugal casting machines, metal mold gravity casting machines, and other related casting machines Basic concepts of energy, important mechanisms and components, main process flow and parameters.

The formulation of GB/T 46639 provides a foundation for the development and revision of standards in the field of casting machinery, as well as for technical documents and related scientific and technological publications.

It provides a unified basis for terminology.

Note 2.Other permanent casting units are also applicable.

Biscuit; slug

leftover materials

The remaining metal that solidifies and is ejected along with the casting in the mold cavity of a cold chamber die casting machine.

The tube mold is cantilevered and fixed to one or both ends of the machine spindle, or to a flange connected to one or both ends of the spindle in a horizontal centrifugal casting process.

Machine manufacturing.

casting area

The die casting machine allows the maximum projected area of the casting (including the gating system, venting system, and overflow system) on the mold parting surface.

Note. Other permanent casting units are also applicable.
