Description

Technical Field

[0001] This utility model relates to the field of metal casting, specifically a casting mold. Background Technology

[0002] Casting molds are an important part of the casting process. In traditional casting molds, liquid metal gradually cools and solidifies in the cavity of the mold during metal casting. Traditional casting molds have thick walls and poor heat dissipation performance. The cooling rate of the liquid metal is slow, and the solidification process is long, resulting in long intervals between metal casting processes and low casting efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a casting mold that overcomes the aforementioned defects in the prior art.

[0004] According to the present invention, a casting mold includes an upper mold and a lower mold, the upper mold and the lower mold are symmetrically arranged vertically, and a cavity is opened on the side of the upper mold and the lower mold that are close to each other. A pouring gate communicating with the cavity is opened on the side of the upper mold that is away from the lower mold. A plurality of heat dissipation grooves are opened on the side of the upper mold and the lower mold that are opposite to each other, and a heat dissipation structure is fixed in each heat dissipation groove. The structure includes a heat dissipation shell, which is hollow inside and open at both the top and bottom. Multiple evenly distributed heat dissipation fins are fixed inside the heat dissipation shell, and heat dissipation pipes that pass through all the heat dissipation fins are fixed inside the heat dissipation shell. Liquid water flows through the heat dissipation pipes.

[0005] Optionally, the upper mold and the lower mold have multiple through holes on their outer periphery that correspond to the two ends of the heat dissipation pipe. A connecting pipe is embedded in the through hole and the connecting pipe is connected to the heat dissipation pipe.

[0006] Optionally, a connecting part is fixed at one end of the connecting pipe near the heat dissipation pipe, both ends of the heat dissipation pipe are flush with the side wall of the heat dissipation groove, and the connecting part is embedded in the end of the heat dissipation pipe.

[0007] Optionally, the connecting pipe is made of high-temperature resistant rubber.

[0008] Optionally, the upper mold and the lower mold are fixedly connected by bolts.

[0009] The beneficial effects of this utility model are as follows: This utility model fixes the upper mold and the lower mold together with bolts. Liquid metal is injected into the cavity through the pouring port and formed inside. During this process, the heat dissipation fins accelerate the heat transfer of the mold. At the same time, liquid water enters the heat dissipation pipe through a connecting pipe at both ends of the heat dissipation pipe, and after flowing in the heat dissipation pipe, it is discharged from the connecting pipe at the other end, which further improves the heat dissipation effect of the mold, accelerates the cooling and forming speed of the liquid metal, and improves the casting efficiency.

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up and down and left and right are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. The specific features of this casting mold are described in detail below: One embodiment of this utility model: Reference Figures 1-5This utility model provides a casting mold, including an upper mold 10 and a lower mold 11, which are symmetrically arranged vertically. A cavity 15 is formed on the side of the upper mold 10 and the lower mold 11 that is close to each other. A pouring port 14 communicating with the cavity 15 is formed on the side of the upper mold 10 that is away from the lower mold 11. Several heat dissipation grooves are formed on the sides of the upper mold 10 and the lower mold 11 that are opposite to each other, surrounding the cavity 15. A heat dissipation structure is fixed inside each heat dissipation groove. The structure includes a heat dissipation shell 20, which is hollow inside and open at both ends. Multiple evenly distributed heat dissipation fins 21 are fixed inside the heat dissipation shell 20. A heat dissipation pipe 22 passing through all the heat dissipation fins 21 is fixed inside the heat dissipation shell 20, and liquid water flows through the heat dissipation pipe 22. Multiple through holes corresponding to the two ends of the heat dissipation pipe 22 are formed on the outer periphery of the upper mold 10 and the lower mold 11. A connecting pipe 12 is fitted into the through holes, and the connecting pipe 12 connects to the heat dissipation pipe 22. 2. A connecting pipe 12 is connected to a connecting part 13 at one end near the heat dissipation pipe 22. Both ends of the heat dissipation pipe 22 are flush with the side wall of the heat dissipation groove. The connecting part 13 is embedded in the end of the heat dissipation pipe 22. The connecting pipe 12 is made of high temperature resistant rubber. The connecting pipe 12 for injecting water into the heat dissipation pipe 22 is connected to a water pump through a pipe. The connecting pipe 12 for draining water is connected to a water storage tank through a pipe. The upper mold 10 and the lower mold 11 are fixedly connected by bolts 16. A rib plate is provided between the side wall of the cavity 15 and the side wall of the upper mold 10 between two adjacent heat dissipation structures to increase the strength of the side wall of the cavity 15. A cylindrical connecting column is fixed in the middle of the rib plate. A threaded hole extending upward through the lower mold 11 is opened in the connecting column on the lower mold 11. A countersunk hole extending downward through the upper mold 10 is opened in the connecting column on the upper mold 10. The bolt 16 passes through the countersunk hole on the upper mold 10 and is threaded into the threaded hole on the lower mold 11.

[0014] In use, the lower mold 11 and the upper mold 10 are first fixedly connected to each other by bolts 16. The molten liquid metal is then injected into the cavity 15 through the pouring port 14, where it cools and solidifies. During this process, a water pump is started to inject liquid water into the heat dissipation pipe 22 through the connecting pipe 12. After flowing through the heat dissipation pipe 22, the water is discharged through the connecting pipe 12 at the other end. The liquid water, the heat dissipation pipe 22, and the heat dissipation fins 21 accelerate the heat transfer in the cavity 15, thereby accelerating the cooling speed of the liquid metal and improving the casting efficiency.

[0015] When installing the heat dissipation structure, the heat dissipation structure is first fixed in the heat dissipation groove, and the end of the heat dissipation pipe 22 is aligned with the through holes on the lower mold 11 and the upper mold 10. Then, the connecting pipe 12 is embedded in the through hole, and the connecting part 13 is embedded in the end of the heat dissipation pipe 22, so that it communicates with the end of the heat dissipation pipe 22 and remains sealed.
