[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1-4. This utility model provides an embodiment of a master alloy casting mold, comprising a lower mold fixing plate 3 and an upper mold fixing plate 4. The upper mold fixing plate 4 is provided with a pair of upper detachable molds 15, with upper forming grooves 18 on their surfaces. The upper mold fixing plate 4 is provided with an upper connecting groove 16, which is positioned between the two upper detachable molds 15. An injection port 17 is provided in the upper connecting groove 16, which connects the upper connecting groove 16 to the upper forming groove 18. The lower mold fixing plate 3 is provided with a lower detachable mold 13, with a lower forming groove 20 on its surface. The lower mold fixing plate 3 is provided with a lower connecting groove 14 that cooperates with the upper connecting groove 16. After the master alloy molten liquid is injected from the injection port 7 on the connecting plate 6 and the pressure plate 5, it flows sequentially through the upper connecting groove 16 and is then evenly distributed into the two upper forming grooves 18 through the injection port 17, while precisely docking with the closed cavity formed by the lower forming groove 20. Because of the smooth channel design and the absence of obvious dead corners, the molten liquid experiences low resistance and uniform filling speed during flow.

[0025] In this embodiment, a bearing plate 2 is provided on the lower surface of the lower mold fixing plate 3. The bearing plate 2 and the lower mold fixing plate 3 are detachably connected by bolts. A positioning sleeve 11 is fixedly connected to the upper surface of the bearing plate 2 and passes through the lower mold fixing plate 3. A pressure plate 5 is provided on the upper surface of the upper mold fixing plate 4. A positioning post 10 is fixedly connected to the lower surface of the pressure plate 5 and passes through the upper mold fixing plate 4. A fixing post 8 is provided on the pressure plate 5. The pressure plate 5 is detachably connected to the upper mold fixing plate 4 through the fixing post 8. If the product size needs to be adjusted, simply loosen the connecting parts that fix the upper detachable mold 15 and the upper mold fixing plate 4, and the lower detachable mold 13 and the lower mold fixing plate 3, remove the original mold and the molding part 19, and replace it with a part that matches the new specifications. This detachable structure allows a set of molds to quickly adapt to multiple production needs without having to customize a complete set of molds for each product, which significantly reduces the mold procurement cost and improves the space utilization and production switching efficiency of the equipment.

[0026] In this embodiment, a connecting plate 6 is fixedly connected to the pressure plate 5. The connecting plate 6 and the pressure plate 5 are provided with injection ports 7, and the injection ports 7 are interconnected with the upper connecting groove 16. The upper mold fixing plate 4 and the bearing plate 2 are provided with reserved grooves 9, and the reserved grooves 9 are threaded with auxiliary parts 12. The lower surface of the bearing plate 2 is detachably connected with a fixed base 1. The upper forming groove 18 and the lower forming groove 20 are provided with forming parts 19. The bearing plate 2 is provided with a push rod 21, the upper end of the push rod 21 passes through the lower mold fixing plate 3 and is placed in the lower connecting groove 14. During the mold closing process, the cooperation between the positioning sleeve 11 and the positioning post 10 achieves precise guidance. When the upper mold fixing plate 4 and the lower mold fixing plate 3 are closed, the positioning post 10 on the lower surface of the pressure plate 5 will pass through the positioning sleeve 11 on the bearing plate 2 and descend. The gap between the post and the sleeve restricts the displacement of the mold in the horizontal direction, ensuring that the docking error between the upper forming groove 18 and the lower forming groove 20 does not exceed the design threshold.

[0027] When it is necessary to produce master alloy products of different specifications and shapes, the upper detachable mold 15, the lower detachable mold 13 and the forming part 19 can be directly disassembled and replaced. In the casting operation, the injection port 7, the upper connecting groove 16, the injection port 17 and the upper forming groove 18 and the lower forming groove 20 form a complete and continuous casting channel. The top of the push rod 21 is placed in the lower connecting groove 14. After cooling in the connecting pipe, the excess parts can be removed by pushing the push rod 21. During the mold closing process, the cooperation between the positioning sleeve 11 and the positioning pin 10 achieves precise guidance.

[0028] Both the upper detachable mold 15 and the lower detachable mold 13 are detachable and replaceable, allowing one set of molds to adapt to the production needs of master alloy products of different specifications and shapes. This eliminates the need to customize a complete set of molds for each product, reducing production costs and improving the reusability and production adaptability of the molds. The injection port 7, upper connecting groove 16, injection port 17, upper forming groove 18, and lower forming groove 20 form a continuous casting channel, allowing the master alloy molten metal to fill the forming groove smoothly and evenly, which helps to ensure the stability of product forming quality. The matching design of the positioning sleeve 11 and the positioning pin 10 can play a precise guiding and positioning role during the mold closing process of the upper and lower molds, ensuring that the upper forming groove 18 and the lower forming groove 20 are accurately aligned, avoiding product size deviations or scrap due to mold closing misalignment, and improving the dimensional accuracy and forming stability of the product.

[0029] This specification describes the embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined.
