Problems solved by technology

[0004] Aiming at the problem that the casting mold currently used for liquid metal forming is a sand mold, the solidification speed of the metal cannot be flexibly controlled and the surface finish of the prepared casting is poor, and the current method for manufacturing the sand mold has the disadvantages of large dust, environmental pollution and complicated process. The present invention Provide a casting mold that can be adjusted according to the solidification needs of different positions of the casting and can obtain castings with a smooth surface, and at the same time provide a manufacturing method for the casting mold that has a short manufacturing cycle, low cost, no pollution, and can be recycled and reused

specific Embodiment approach 1

[0012] Specific embodiment one: present embodiment is a kind of fast intelligent environmental protection mold, and it comprises sand box 1, with reference to figure 1 , the sand box 1 has four frames, the sand box 1 is filled with heat conduction wires 2 parallel to the frame, and the ends of all heat conduction wires 2 form a shape consistent with the shape of the casting to be formed.

[0013] The preparation process of the casting mold is as follows: set a sand box 1 with four frames, install a heat conducting wire 2 placed in the sand box 1 parallel to the direction parallel to the frame, and make the ends of the heat conducting wire 2 in the sand box 1 form a The shape consistent with the shape of the casting is sufficient.

specific Embodiment approach 2

[0014] Specific embodiment two: the difference between this embodiment and specific embodiment one is that a frame of the sand box 1 is a movable splint 1-1, refer to figure 2 , image 3 , the movable splint 1-1 is movably connected with two adjacent frames, and is fixed by a fixing member 5 . The function of the movable splint is to make the heat conduction wires in the sand box more closely arranged, so as to better ensure the smooth forming of the casting and the smoothness of the casting surface.

specific Embodiment approach 3

[0015] Specific embodiment three: the preparation process described in this embodiment is as follows in sequence, with reference to figure 2 , image 3 :

[0016] a. First make the model 3 of the casting and determine the material of the heat conducting wire 2 according to the casting to be formed. The heat conducting wire 2 can be any one, two or three of metal wire, alloy wire and non-metal wire. The casting model can be manufactured by rapid prototyping system or other model making process, and the material of the heat conduction wire can be determined according to the numerical simulation results, and the heat conduction wire that needs to be cooled or slowly cooled can be arranged in the place where special cooling or heat preservation is required. Metal wires or alloy wires made of materials with low thermal conductivity can be used for some parts, for example, thermal conductive wires made of nickel alloy, titanium alloy or tungsten alloy materials with low thermal co...

Abstract

The invention relates to a quick intelligent environment-friendly mould and relative producing method, while said mould is used to mold liquid metallic. And it can solve the defects of present sand mould that uncontrolled solidify speed, worse surface fineness and environment pollution. The inventive sand tank (1) is filled with thermal conductive wires (2) parallel with frame; the ends of said thermal conductive wires (2) form the shape in the same of needed cast. And the production of cast comprises: arranging thermal conductive wires (2) parallel to the frame inside the sand tank (1); and shaping their ends into needed cast. The inventive cast can adjust thermal conductive speed according to the solidified position of cast, to attain high surface fineness. And it has short producing period, lower cost, and wider application, without pollution.

Description

technical field [0001] The invention relates to a casting mold for liquid metal forming and a manufacturing method thereof. Background technique [0002] Liquid metal forming is a method of metal forming with a long history. With the continuous advancement of science and technology, the liquid metal forming method has also undergone significant changes, from sand casting to metal casting, magnetic shot casting, freezing casting, etc., both in terms of molding methods and molding materials. The key part that determines the forming - the casting mold has always been the focus and hot spot of research, and has been highly valued by scholars from all over the world. The role of the mold is mainly forming, but also responsible for the role of heat transfer. However, there are two unresolved problems for many years. One is the casting material. At present, the main molding method responsible for casting production is still sand casting, although the molding method has undergone ...
