DETAILED DESCRIPTION

[0044] Any feature disclosed in this specification, unless stated otherwise, can be replaced by alternative features serving the same, equivalent or similar purpose, to achieve the same, equivalent or similar result.

[0045] Example 1

[0046] To achieve the manufacture of the composite metal plate as shown in Figure 1 and Figure 2 , the outer metal 1 is an outer metal body, and the inner core 2 is an inner core box. A plurality of inner core boxes 301 as shown in Figure 3 are made, which have an inner core boss 302, a screw hole 303, an inner core boss plane 304, an inner core plane 305, and a distance H1 between the inner core boss plane 304 and the inner core plane 305 being the thickness of the outer metal body. An upper mold plate 4 as shown in Figure 7 and Figure 5 and a plurality of inner core boxes 301 and a lower mold 7 are also provided. The upper mold plate 4 has a tensioning screw head counterbore 404 and a tensioning screw hole 402 corresponding to each inner core box 301, a spring force plane 403, an upper mold upper plane 405, and an upper mold plate bottom plane 401. The inner core box 301 and the corresponding hole on the upper mold plate 4 are assembled by a spring 6 with a thread 501, and a tensioning screw 5 as shown in Figure 6 has a thread 501, a spring force plane 502, and an air hole 503. The assembly details are shown in Figure 5As shown, the tension screw 5 passes through the tension screw hole 402. The spring force plane 502 and the screw hole 303 are engaged. A spring 6 supports the spring force plane 502 and the inner core boss plane 304, so that the inner core boss plane 304 and the upper template bottom plane 401 are in contact. After the molten metal is poured into the vent hole 503, the core box temperature rises. The air inside the core box expands thermally and is discharged from the vent hole 503. There is a gap A between the tension screw hole 402 and the tension screw 5 passing through it. A is greater than or equal to the distance the core box moves after the composite metal plate is poured and cooled. The specific steps are as follows:

[0047] Step 1: After the inner core box 301 and the upper template 4 are assembled according to the above instructions, they are placed below the lower mold 7, and molten metal is injected into the solution tank 701 in the lower mold 7;

[0048] Step Two: As Figure 8 As shown, the upper mold moves downward and the lower mold closes;

[0049] Step 3: Apply pressure P to the upper mold to induce solidification of the molten metal as follows: Figure 9 As shown, the pressure P can be in a wide range, from 5 MPa to 100 MPa. Depending on the requirements of the application, the minimum pressure test can be determined first.

[0050] Step Four: As Figure 10 As shown, the upper template 4 drives the inner core box 301 and the outer metal cladding 1 to rise and separate from the lower template;

[0051] Step 5: As Figure 11 As shown, the tension screw 5 and spring 6 are removed, separating the upper template 4 and the outer metal cladding 1 to form a composite metal plate with several screw holes.

[0052] Step Six: In the figure, H1 is determined by the thickness of the inner core boss, and H2 is determined by the total amount of injected molten metal. When it is necessary to adjust the size of H2, the total amount of molten metal can be increased or decreased. The screw holes are closed to form a complete composite metal plate. In this embodiment, the inner core box 301 is made of steel plate, the inner core boss 302 is made of aluminum, and the outer cladding metal 1 is made of aluminum. The inner core boss 302 and the outer cladding metal 1 can also be formed by replacing aluminum with materials such as copper or stainless steel.

[0053] The dimensions of the inner core box and its outer cladding include the inner core box side length L, inner core box height H, inner core box spacing L1, distance from the inner core box side edge to the perimeter of the component L2, outer metal thickness H1 and H2 in the height direction of the inner core box, and inner core box material thickness δ (as shown in the figure). Figure 3 The dimensions are generally determined by experiments. In this embodiment, the reference dimensions are L = 200 mm, H = 75 mm, L1 = L2 = 6 mm, H1 = H2 = 5 mm, and δ = 2 mm.

[0054] Example 2

[0055] The inner core box 301 differs from that in Example 1, such as Figure 4 As shown, the inner core box 301 has a magnetically attractable boss 306 and a magnetically attractable boss plane 307. There is a magnet on the bottom plane 401 of the upper mold. The magnetically attractable boss plane 307 on the magnetically attractable boss 306 is attracted and attached to the bottom plane 401 of the upper mold by the magnet. When the molten metal 8 begins to solidify and shrink, the inner core 3 with the boss can be translated with the bottom plane 401 of the upper mold. The magnet can be a permanent magnet or an electromagnet. Ventilation holes can be opened on the inner core box with the magnetically attractable boss 306. There are also corresponding ventilation holes on the upper mold position so that when the temperature of the molten metal is transferred to the air in the inner core box, the heated air is discharged. When the metal outer casing is a non-ferrous metal or stainless steel material that is not magnetically attractable, the magnetically attractable boss 306 can be removed after casting and then filled with a material that is the same as the outer casing metal 1.

[0056] Example 3

[0057] Unlike the above embodiments, as Figure 13 As shown, several auxiliary bosses 308 are distributed on the outside of the inner core boss 302. The upper surface of the auxiliary bosses 308 and the inner core boss plane 304 rest on the bottom plane 401 of the upper template to increase the stability of the inner core box.

[0058] Example 4

[0059] Unlike the above embodiments, a heat insulation layer 9 is wrapped around the outside of the inner core box 301. This layer can be made of aluminum silicate fiber paper and adhered to the outside of the inner core box 301 with heat-resistant adhesive (e.g., ...). Figure 14 As shown), this method eliminates the need for preheating the inner core box 301, and the final finished component is as follows. Figure 15 As shown, the insulation layer 9 can also be applied by brushing or dipping refractory coating onto the outer surface of the core box and then dried before use.

[0060] Example 5

[0061] Will Figure 11 and Figure 15 The screw holes 303 of the inner core box 301 and the inner core boss 302 in the schematic component are closed to form an integral hollow composite component. The sealing material can be the same as the outer metal and can be connected to the outer metal by bonding or welding.

[0062] Example 6

[0063] When the outer metal cladding is made of rust-proof material, Figure 12 The magnetically attached boss 306 in the middle can be removed by machining and replaced with rust-proof material. The rust-proof material can be connected to the outer metal by bonding or welding.

[0064] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement not through creative labor should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
