Introduction

The series of standards for die casting mold parts are the basic technical documents for the design, manufacture, inspection and acceptance of die casting mold parts. The purpose of the formulation of the "Parts" is to unify the basic structure and specifications of die-casting mold parts, standardize their technical requirements, and improve the product quality of domestic die-casting mold parts. Increase the quantity and utilization rate of standard parts and reduce production costs. In recent years, with the introduction of integrated die-casting product molding technology, die-casting molds have continued to develop towards large-scale, and mold hoisting has become a mold manufacturing An important part of creation. The document developed this time is GB/T 4678 Part 20, which complies with the compilation requirements of GB/T 1.1-2020. The mold is stably and safely hoisted, so that it can timely and comprehensively reflect the latest mature technology content of the die-casting mold industry, and at the same time, it can be marked with other die-casting mold parts. Quasi-phase coordination and matching are of great significance to promote the technological progress and upgrading of the die-casting mold industry and the extension of the industrial chain. After adding Part 20, the number of GB/T 4678 die casting parts standards has increased to the following 20 parts. --- Part 1.Template; --- Part 2.Circular inserts; --- Part 3.Rectangular inserts; --- Part 4.Square guide pillars; --- Part 5.Circular guide cylinders; --- Part 6.Guide bushing with head; --- Part 7.Straight guide bushings; --- Part 8.Push plate; --- Part 9.Push plate guide column; --- Part 10.Push plate guide sleeve; --- Part 11.Push rod; --- Part 12.Reset lever; --- Part 13.Push plate gasket; --- Part 14.Limiting nails; --- Part 15.Spacers; --- Part 16.Flat push rods; --- Part 17.Push pipe; --- Part 18.Support columns; --- Part 19.Positioning elements; --- Part 20.Lifting columns. Each part stipulates the structure, technical requirements, material requirements, marking, etc. of one of the parts. According to the requirements, design and manufacture die-casting mold parts according to the corresponding parts. Die casting parts Part 20.Lifting columns
