Spiral core-pulling mechanism of die-casting die

Abstract

The invention provides a die-casting die spiral core-pulling mechanism which comprises a core-pulling mechanism body, the core-pulling mechanism body comprises a die, the die comprises a lower die and an upper die, a fixing base is installed between the upper die and the lower die, a movable column is installed on the fixing base, a handle is fixed to one end of the movable column, and a screw is installed on the handle. A fixing hole is formed in the top of the upper die, a fixing bolt is installed in the fixing hole, and an open hole is formed in the upper die. According to the spiral core-pulling mechanism of the die-casting die, the movable column is driven to move through the handle in the later period, the movable column drives the whole threaded column to move on the limiting ring through the supporting column, redundant waste materials are scraped through the limiting ring during displacement, burrs in the arc-shaped groove are reduced while the redundant waste materials are scraped through the limiting ring, and therefore the working quality is improved; the use is convenient.

Description

technical field [0001] The invention relates to the field of die-casting mold equipment, in particular to a spiral core-pulling mechanism of a die-casting mold. Background technique [0002] Mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection molding, blow molding and low foaming molding. Die casting mold is a large category of molds. It is a method of casting liquid forging. It is a process completed on a special die-casting die forging machine. Its basic process is: the molten metal is cast and filled into the cavity of the mold at a low or high speed. The mold has a movable cavity surface, which is cooled with the molten metal. Process pressure forging not only eliminates the shrinkage cavity and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state. The traditional thread products with starting position requirements are all ordinary spiral core-pulli...

[0002] Mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection molding, blow molding and low foaming molding. Die casting mold is a large category of molds. It is a method of casting liquid forging. It is a process completed on a special die-casting die forging machine. Its basic process is: the molten metal is cast and filled into the cavity of the mold at a low or high speed. The mold has a movable cavity surface, and it cools with the molten metal Process pressure forging not only eliminates the shrinkage cavity and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state. The traditional thread products with starting position requirements are all ordinary spiral core-pulling structures. Assembly The initial position of the thread in the mold cannot be accurately positioned, and the direction of the thread can only be adjusted by using the pre-made marks. This method will lead to inaccurate initial position of the thread, which will affect the quality of the subsequent processed products. In addition , the existing core-pulling structure is not easy to install, and requires extremely high proficiency of assemblers, so it cannot meet the needs of different situations
