Embodiment 1

[0021] Such as Figure 1~5 As shown, a combined cold iron for core shooting and 3D printing casting technology, including a cold iron 1 with suspension, a rectangular opening 2 is opened in the middle of the side, and is set along the rectangular opening 2 to the inside of the cold iron 1 with suspension There is an arc-shaped cavity, the central angle α of the arc-shaped cavity 9 is less than 90 degrees and the angle opening is biased towards the square cold iron, which runs through the hanging cold iron, and passes through the straight hole of the arc-shaped cavity 9, and is arranged on the circular arc-shaped cavity 9. The fan-shaped card 8 inside the arc-shaped cavity 9 passes through the straight hole and the rotating shaft 3 that is rotatably connected to the fan-shaped card 8. The fan-shaped card 8 can rotate around the axis through the rotating shaft 3, and also includes square cooling iron 6. The side is It is square, and has the same area and shape as the surface whe...

Embodiment 2

[0029] Such as Figure 6 As shown, a cold iron accommodation cavity is set on the side of the sand core 10, and the assembled cold iron 1 with suspension is put in from the side. In order to prevent the suspended cold iron 1 from falling, hold the suspended cold iron 1 with your hands , and then gradually put into the square chill 6, after the square chill 6 is put into the sand core 10, by the self gravity of the fan-shaped card 8, the fan-shaped card 8 is rotated into the draw-in groove 7 of the square chill 6.

Abstract

The invention provides a combination chilling block for core shooting and 3D printing casting technology. The combination chilling block comprises a chilling block provided with a hanger, a circular arc shaped cavity, a sector blade, straight holes, a rotating shaft, a quadrate chilling block and a clamping groove, wherein a rectangular port is formed in the middle of the side surface of the chilling block provided with the hanger; the circular arc shaped cavity is formed by extending into the chilling block provided with the hanger along the rectangular port, and the central angle of the circular arc shaped cavity is less than 90 degrees and the opening of the angle faces the quadrate chilling block; the straight holes pass through the chilling block provided with the hanger through thecavity along two side surfaces which are vertical to the plane where the rectangular port is formed; the sector blade is arranged in the cavity; the rotating shaft passes through the straight holes and is fixedly connected to the sector blade, and the sector blade can rotate by taking the rotating shaft as an axis; the side surface of the quadrate chilling block is quadrate and is as large as theplane where the rectangular port is formed; the clamping groove is formed in the surface, opposite to the plane where the rectangular port is formed, of the quadrate chilling block, and the clamping groove can form a complete circular arc shaped structure with the circular arc shaped cavity; and the sector blade can freely move in the circular arc structure. According to the combination chilling block for the core shooting and 3D printing casting technology, the problem of fixing of the chilling block in shot shooting and 3D printing of a mold core can be solved; the production efficiency is improved; and possible casting defects of a casting can be avoided.

Description

technical field [0001] The invention relates to a combined chill, in particular to a combined chill for core shooting and 3D printing casting techniques. Background technique [0002] Usually, in the production of castings, it is necessary to use cold iron to quench the hot section area, so as to solve the shrinkage and porosity defects in the key area. However, when the core is made by the core-shooting process, it is difficult to place the cold iron on the top surface of the core-shooting core. The main reason is that the sand nozzle of the core shooter is generally set on the top surface of the core shooter. The placement of the cold iron has a great influence on the arrangement of the sand nozzle, and the cold iron is suspended in the air and is affected by gravity and the impact of the sand on the cold iron during sand shooting. The semi-finished cold iron is prone to movement. In addition, when using the 3D printing process to make cores, it is necessary to print out...
