Problems solved by technology

[0003] The traditional casting process has a long production cycle, complex operation and high labor requirements. With the development of science and technology, 3D printing technology has been applied in the casting field. The iron is not easy to be placed in the sand core, and the whole cold iron is not easy to take out after pouring out of the box, resulting in the problem that even if qualified products are produced, the casting may be damaged during the process of taking the cold iron

Embodiment

[0040] Such as Figure 5 As shown, this embodiment provides a cold iron, which is composed of a plurality of steel shots 1, and a cylinder head on a diesel engine is taken as an example. figure 1 — Figure 4 As shown, this embodiment also provides a sand core design method that is convenient for placing cold iron, including the following steps:

[0041] Step 1: Such as figure 1 As shown, 3D modeling software is used to build a 3D casting model according to the requirements of the 2D drawing of the casting;

[0042] Step 2: Such as figure 2 As shown, the 3D casting process model of the casting is designed with 3D modeling software according to the 3D casting model in step 1;

[0043] Step 3: Design a 3D sand core model with 3D modeling software according to the 3D casting process model in step 2;

[0044] Step 4: Such as Figure 4 As shown, the steel shot sand landfill space is set in the three-dimensional sand core model;

[0045] Step 5: 3D print the sand core according to the 3D sand...

Abstract

The invention discloses a cold iron, a sand core designing method for conveniently storing cold iron and a cold iron storing method. The cold iron is formed by being filled with a plurality of steel pill sand, a chilling effect can be played on castings, collapsing is achieved along with sand cores during box opening, no residual exists in a casting cavity, and the qualified rate of the castings is effectively improved.

Description

Technical field [0001] The invention relates to the field of casting technology, in particular to cold iron, a sand core design method convenient for placing the cold iron, and a cold iron placement method. Background technique [0002] Chilled iron is divided into internal chilled iron and external chilled iron. The internal chilled iron is directly inserted into the part that needs to be chilled in the casting cavity and melted with the casting during pouring. It is mainly used for thick and large ferrous metal castings. The external chilled iron is divided into Direct external chilled iron and indirect external chilled iron. Sand-insulated chilled iron is a kind of indirect external chilled iron. As the name suggests, there is a certain thickness of sand between the sand-insulated chilled iron and the chilled castings, so it will not be cast with The castings are welded together. [0003] The traditional casting process has a long production cycle, complex operation and high la...
