[0002] With the development of technology, die casting molds are gradually being used in the manufacturing of shell products. Die casting molds use the cavity between the upper and lower molds to die cast molten aluminum.

[0003] In the existing technology, molten aluminum enters the cavity between the upper and lower molds under external force and is die-cast within the cavity. At this time, the molten aluminum forms along the inner wall of the cavity between the upper and lower molds and forms naturally within a limited space. However, the product formed in the cavity between the upper and lower molds has a low density. Summary of the Invention

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] The purpose of this invention is to provide a casting and forging mold assembly to solve the technical problem of low product density in existing semi-finished products that are naturally formed in the cavity between the upper and lower molds.

[0035] Please refer to the attached document. Figures 1-6 This application provides a casting and forging mold assembly, including an upper mold frame 10, an upper mold core 20, a forging insert 30, a lower mold frame 40, a lower mold core 70, a lower mold movable insert 50, and a lower mold fixed insert 60.

[0036] The upper mold holder 10 serves as a support component for the upper mold core 20 and is located at the top of the casting and forging mold assembly. The upper mold holder 10 supports and fixes the upper mold core 20.

[0037] The upper mold core 20 is connected to the upper mold frame 10. The upper mold core 20 is provided with an upper mold cavity 21 and a flow channel 22. The flow channel 22 is connected to the upper mold cavity 21 and supplies molten aluminum. At this time, the molten aluminum flows to the upper mold cavity 21 through the flow channel 22.

[0038] The forged insert 30 is built into the upper die core 20; the forged insert 30 is installed in the upper die core 20 in a height-adjustable manner; the upper end of the forged insert 30 is used to connect to the first power component. At this time, the forged insert 30 is embedded in the upper die core 20 and is lifted and lowered relative to the upper die core 20 under the drive of the first power component. Optionally, the first power component is a hydraulic cylinder.

[0039] The lower mold base 40 is located on the lower side of the upper mold base 10 and is connected to the upper mold base 10; the lower mold core 70 is installed on the lower mold base 40; the lower mold movable insert 50 is provided with a groove 51.

[0040] The lower mold movable insert 50 is embedded in the lower mold core 70 and can be lifted and lowered on the lower mold core 70. The lower mold movable insert 50 is provided with the groove 51. The lower end of the lower mold movable insert 50 is used to connect the second power component. At this time, the lower mold movable insert 50 is embedded in the lower mold core 70 and is lifted and lowered relative to the upper mold core 20 under the drive of the second power component. Optionally, the second power component is a hydraulic cylinder.

[0041] When the upper mold core 20 and the lower mold core 70 are in the closed state, molten aluminum is initially formed between the upper mold core 20 and the lower mold core 70 to form a semi-finished product. The semi-finished product is arranged relative to the lower mold movable insert 50 and descends as the lower mold movable insert 50 descends. The semi-finished product flows along the groove 51 under the forging action of the forging insert 30, so that the semi-finished product is further compressed under the forging action of the forging insert 30. As a result, a portion of the semi-finished product overflows into the groove 51 during the compression process, so that the semi-finished product undergoes plastic deformation after forging, thereby allowing the product to achieve the forging effect.

[0042] At this time, a portion of the semi-finished product overflows during the forging process, and a portion of the semi-finished product flows into the groove 51 and naturally forms in the groove 51. At this time, the forged semi-finished product has a surrounding edge, which corresponds to a portion of the semi-finished product.

[0043] The upper mold cavity 21 is arranged relative to the lower mold fixed insert 60, and forms a forming cavity between the upper mold cavity 21 and the lower mold fixed insert 60. Molten aluminum flows into the forming cavity and is initially formed in the forming cavity.

[0044] When the semi-finished product needs to be forged, the lower die movable insert 50 descends relative to the lower die core 70 and forms an overflow port 61. The groove 51 is located on the outside of the overflow port 61 and communicates with the overflow port 61, so that the semi-finished product overflows into the groove 51 under the forging action of the forging insert 30.

[0045] At this time, the overflow port 61 and the groove 51 are connected, and the semi-finished product overflows into the groove 51 under the forging action of the forging insert 30, so that the product can produce sufficient plastic deformation after forging, so that the performance of the product can achieve the effect of forging.

[0046] The groove 51 is arranged around the outer periphery of the overflow port 61. The groove 51 and the overflow port 61 are on the same horizontal plane and are interconnected. The groove 51 is a U-shaped groove and is arranged along the outer contour of the overflow port 61 so that the groove 51 can communicate with the overflow port 61 in multiple directions, which facilitates the overflow of the semi-finished product in multiple directions.

[0047] In addition, temperature probes 80 are embedded in the lower mold core 70, the lower mold movable insert 50, and the lower mold fixed insert 60. The temperature probes 80 are embedded vertically in the lower mold core 70, the lower mold movable insert 50, and the lower mold fixed insert 60, and are used to detect the temperature at the lower mold core 70, the lower mold movable insert 50, and the lower mold fixed insert 60.

[0048] The simultaneous setting of three locations—the lower mold core 70 corresponding to the flow channel, the lower mold movable insert 50 corresponding to the groove 51, and the lower mold fixed insert 60 corresponding to the forming cavity—allows for more precise detection of the temperature of important parts of the casting and forging mold components. This enables the adjustment of the machine's forming parameters through appropriate temperature changes, resulting in more stable product forming.

[0049] Furthermore, the upper mold core 20 is embedded with a backstop block 90, which is arranged relative to the flow channel 22 and is vertically connected to the upper mold core 20. At this time, the backstop block 90 descends relative to the upper mold core 20 and passes through the flow channel 22 in a vertical direction to divide the flow channel 22 so as to stop the flow of molten aluminum in the flow channel 22.

[0050] Optionally, the forging insert 30 is disposed on the upper side of the semi-finished product, and the overflow port 61 is disposed on the lower side of the semi-finished product. During forging, the forging insert 30 applies pressure to the semi-finished product from top to bottom. The semi-finished product overflows during the forging process and overflows into the groove 51, so that the semi-solid molten aluminum in the forming cavity is fully drawn from top to bottom, allowing the forged semi-finished product to produce sufficient plastic deformation, so that the final solidified product has the performance of forging.
