[0018] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0019] The present application embodiment discloses a brake forming die. Figure 1-Figure 4 A brake molding mold includes a support plate 12 and a support frame 1 and support legs 4 installed at four corners of the lower surface of the support plate 12. The support plate 12 and the support legs 4 cooperate to ensure the stability of the bottom of the mold equipment. At the same time, a mold base 11 is rotatably connected above the support plate 12. A plurality of mold barrels 10 are integrally formed inside the mold base 11, which facilitates the rotation of the mold base 11 above the support plate 12, driving the plurality of mold barrels 10 to rotate, and realizing continuous compression molding;

[0020] At the same time, multiple groups of spring sheets 13 are arranged circumferentially on the outer circle of the mold barrel 10, and each group of spring sheets 13 is radially equidistantly arranged outside the mold barrel 10. A U-shaped frame 9 is fixed to the lower surface of the support plate 12, and the U-shaped frame 9 provides support under the fixed column 6. In addition, a fixed column 6 is installed on the upper surface of the U-shaped frame 9, and an ejection hydraulic rod 16 is installed on the top of the fixed column 6. A circular plate 15 is installed on the top of the ejection hydraulic rod 16. A plurality of touch rods 14 are distributed circumferentially on the upper surface of the circular plate 15. The circular plate 15 is pushed upward by the top of the ejection hydraulic rod 16, and then the circular plate 15 drives the circumferentially distributed touch rods 14 to move upward synchronously, so that the transverse protrusion on the top of each touch rod 14 can continuously touch the corresponding radially arranged plurality of spring sheets 13 as the circular plate 15 moves upward, thereby causing the mold barrel 10 itself to vibrate continuously, causing the compression-molded sand core to loosen inside the mold barrel 10, and further facilitating the separation between the sand core and the mold barrel 10.

[0021] Reference Figure 1 and Figure 2 An I-shaped gear ring 7 is fixedly connected to the bottom of the mold base 11, and the I-shaped gear ring 7 is sleeved on the center of the support plate 12. A driving motor 8 is installed on one side of the upper surface of the U-shaped frame 9, and a driving gear 5 is installed on the top of the driving motor 8, and the driving gear 5 is meshed with the I-shaped gear ring 7. When in use, by starting the driving motor 8, the output end of the driving motor 8 drives the driving gear 5 to rotate, and then the driving gear 5 can drive the I-shaped gear ring 7 to rotate, and then the I-shaped gear ring 7 can drive the mold base 11 to rotate, so that several mold barrels 10 can rotate to achieve continuous automatic compression molding.

[0022] Reference Figure 4 A top plate 18 is attached to the inner wall of the mold barrel 10, a top rod 17 is fixed at the center of the top plate 18, and the outside of the top rod 17 passes through the bottom of the mold barrel 10, so that the circular plate 15 moves up to push the bottom of the top rod 17 to move, and then pushes the top plate 18 to move up inside the mold barrel 10, so as to facilitate the separation of the sand core from the mold barrel 10 after compression molding.

[0023] Reference Figure 1and Figure 2 A downward pressing hydraulic rod 2 is installed on the top of the support frame 1, and a compression molding head 3 is installed at the bottom of the downward pressing hydraulic rod 2. By starting the downward pressing hydraulic rod 2, the bottom of the downward pressing hydraulic rod 2 pushes the compression molding head 3 into the mold barrel 10, so that the sand core placed at the barrel mouth of the mold barrel 10 can be compression molded.

[0024] Reference Figure 3 and Figure 4 Each contact rod 14 corresponds to each group of spring sheets 13 in a one-to-one distribution angle, and the upward movement path of the protruding part of the contact rod 14 partially overlaps with the distribution position of the corresponding arranged spring sheets 13, ensuring that when the contact rod 14 moves upward, its protruding part can touch the corresponding spring sheet 13.

[0025] The implementation principle of a brake forming mold in the embodiment of the present application is:

[0026] When the compression-molded sand core needs to be ejected from the mold barrel 10, the ejection hydraulic rod 16 can be started, and then the top of the ejection hydraulic rod 16 pushes the circular plate 15 upward, and then the circular plate 15 moves upward to drive a plurality of circumferentially distributed contact rods 14 to move upward synchronously, so that the transverse protruding portion on the top of each contact rod 14 can continuously contact with a plurality of radially arranged spring sheets 13 as the circular plate 15 moves upward, thereby causing the mold barrel 10 itself to vibrate continuously, causing the compression-molded sand core to loosen inside the mold barrel 10, effectively reducing the instantaneous pulling force on the subsequent sand core when it is ejected, avoiding damage to the sand core as much as possible, and improving the processing quality of the sand core.
