For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] As shown in the drawings, the present application comprises an upper die 1 and a lower die 2, The upper die 1 has a group of upper profiling grooves at the bottom, the lower die 2 has a group of lower profiling grooves at the top, one end of the lower profiling grooves is a liquid inlet, and the lower die 2 is provided with a pouring groove 3 in communication with the liquid inlet.

[0030] The lower profiling groove comprises a lower main body area 4, a lower half-pipe area 5 and a sliding groove 6, the inlet end of the lower half-pipe area 5 is in communication with the lower main body area 4, a sliding block 7 is arranged in the sliding groove 6, an inner hole forming rod 8 is arranged on the end face of the sliding block 7, and the inner hole forming rod 8 is located in the lower half-pipe area 5.

[0031] A group of inlay holes 9 are opened in the lower main body area 4, and a profiling forming column 10 is arranged in each of the group of inlay holes 9, and the end of the profiling forming column 10 is located in the lower main body area 4.

[0032] A group of A guide dams 11 are arranged at the inlet end of the lower main body area 4, and a group of B guide dams 12 are arranged in the pouring groove 3 and coupled with the A guide dams 11.

[0033] A block 13 is provided at the connection between the inner forming rod 8 and the slider 7. The block 13 is located inside the outlet end of the lower half-pipe region 5, and the outer wall of the block 13 is coupled to the inner wall of the outlet end of the lower half-pipe region 5.

[0034] The tail of slider 7 has a push-pull groove 14 with a T-shaped cross section.

[0035] The upper contouring groove includes an upper main body area 15, an upper half-tube area 16, and a slider positioning area 17. The inlet end of the upper half-tube area 16 is connected to the upper main body area 15, and the slider positioning area 17 is connected to the outlet end of the upper half-tube area 16. After the upper mold 1 and the lower mold 2 are closed, the upper half-tube area 16 and the lower half-tube area 5 are merged into a tubular forming area, and the upper part of the slider 7 is located in the slider positioning area 17.

[0036] Mold mounting plates are provided at the top of the upper mold 1 and the bottom of the lower mold 2.

[0037] The upper mold 1 is provided with a forming top plate 18, which is located on the top of the B diversion dam 12.

[0038] Example 1: As shown in the attached document Figure 4 As shown, the slider 7 is installed in the groove 6, the inner hole forming rod 8 is located in the lower half-tube area 5, and then the imitation forming column 10 is inserted into the corresponding inlay hole 9. The top shape of the imitation forming column 10 is made according to the shape of the groove of the left spring arm. The top of the imitation forming column 10 matches the inner cavity of the lower main body area 4 to form the lower imitation groove. The A guide dam 11 and the B guide dam 12 are coupled to form an integral guide dam. A casting flow area is formed between two adjacent guide dams to divert the molten metal in the casting tank 3. Each lower imitation groove is connected to three casting flow areas to make the molten metal enter more evenly.

[0039] The upper mold 1 and lower mold 2 are closed, and molten metal is injected into the casting tank 3. The molten metal flows along the casting flow area into the lower and upper contouring tanks, and then flows into the lower half-pipe area 5 and the upper half-pipe area 16. The outlet ends of the lower half-pipe area 5 and the upper half-pipe area 16 are blocked by the plug 13 to prevent the molten metal from overflowing. After casting is completed, the mixture is left to cool and solidify for a period of time. Then, the upper mold 1 is opened, and a special tool is inserted into the push-pull groove 14. The slider 7 moves backward along the slide groove 6, and the inner hole forming rod 8 separates from the left spring support arm blank 100, thus allowing the left spring support arm blank 100 to be removed.

[0040] The molding column 10 is detachable and can be installed as an insert, which facilitates mold modification and mold maintenance.

[0041] The product is made by cutting off the excess part of the left spring arm blank within the casting flow area.
