Description

Technical Field

[0001] The utility model relates to a mold spot cooling system, more specifically, it relates to an integrated spot cooling module group for an extrusion casting mold. Background Art

[0002] A die casting die is a tool for casting metal parts, a tool that completes the die casting process on a dedicated die forging machine.

[0003] Die-casting mold cooling can be divided into external cooling and internal cooling. External cooling is to use a nozzle to spray the mold cavity surface to cool it down after the casting is demolded, and spray a release agent; internal cooling is to circulate cooling water inside the mold, which is the main cooling method for the mold. For the requirements of the extrusion casting process, the extension of the mold life and the shortening of the die-casting molding cycle, it is very important to set a cooling water channel on the die-casting mold to allow the circulating water to pass into the forming insert or core to take the heat out of the mold.

[0004] There are two types of existing internal cooling methods: line cooling and spot cooling. Line cooling requires sufficient space in the mold to open cooling water channels, otherwise it will affect the cooling efficiency. Spot cooling is generally an independent single cooling channel, which requires an inlet pipe and an outlet pipe. Due to limited space, multiple spot cooling cannot be used to achieve cooling, which affects the cooling efficiency.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0027] An integrated spot cooling module for extrusion casting molds, such as Figure 1 , Figure 2 as well as Figure 3 As shown, from bottom to top, it includes a mold core 4, a return water block 3, a water inlet block 2 and a water pipe installation block 1; the mold core 4, the return water block 3, the water inlet block 2 and the water pipe installation block 1 are fitted together.

A plurality of water inlet grooves 21 are provided on the side of the water inlet block 2 close to the water pipe installation block 1, and the ends of the first water inlet holes 11 away from the water inlet pipe 111 are connected to the water inlet groove 21, and a plurality of second water inlet holes 211 are provided on the bottom wall of the water inlet groove 21. The side of the mold core 4 away from the water return block 3 is divided into six cooling areas 41, and the side of the mold core 4 close to the water return block 3 is provided with a plurality of cooling holes 42. The shadows are respectively located in six cooling areas 41, and one end of the second water inlet hole 211 close to the return water block 3 is threadedly connected to the spot cooling needle 5, and the spot cooling needle 5 passes through the return water block 3 and extends into each cooling hole 42 on the mold core 4, and the end of the spot cooling needle 5 away from the cooling hole 42 is connected with the first water inlet hole 11. By setting the water inlet groove 21, as long as the coolant is injected into the water inlet groove 21, it can flow into each second water inlet hole 211 through the water inlet groove 21 and enter the spot cooling needle 5, reducing the setting of the water inlet pipe 111, thereby reducing the use space and ensuring the use efficiency; and setting a plurality of spot cooling needles 5 can water-cool multiple points to ensure the cooling efficiency;

[0029] like Figure 1-Figure 7 As shown, a return water channel connected to the first return water hole 12 is provided between the return water block 3 and the inlet water block 2, and the return water channel includes a plurality of return water grooves 31 opened on the side of the return water block 3 close to the inlet water block 2 and a second return water hole 22 opened on the inlet water block 2 and connected to the first return water hole 12, and the end of the second return water hole 22 away from the first return water hole 12 is connected to the return water groove 31, and a third water inlet hole 32 for the point cooling needle 5 to pass through is opened on the return water block 3, and the end of the third water inlet hole 32 close to the inlet water block 2 is connected to the return water groove 31, and the aperture of the third water inlet hole 32 is larger than the outer diameter of the point cooling needle 5, and the aperture of the cooling hole 42 is larger than the outer diameter of the point cooling needle 5. The outer diameter of the cold needle 5, after the coolant enters the mold core 4 through the cold needle 5, since the aperture of the cooling hole 42 is larger than the outer diameter of the cold needle 5, the excess coolant will overflow from the outer peripheral wall of the cold needle 5, and overflow into the third water inlet hole 32 along the cooling hole 42, and since the aperture of the third water inlet hole 32 is also larger than the outer diameter of the cold needle 5, the coolant will also overflow into the return water groove 31 along the third water inlet hole 32, and then be connected through the second return water hole 22, the first return water hole 12 and the return water pipe 121, and the coolant will be extracted, thereby realizing the circulation effect of the coolant, thereby ensuring the spot cooling effect of the overall structure;

[0030] like Figure 1-Figure 7As shown, a first positioning hole 6 that is interconnected is provided between the water pipe installation block 1 and the water inlet block 2, and a second positioning hole 7 that is interconnected is provided between the water inlet block 2, the return water block 3 and the mold core 4. Positioning pins are inserted into the first positioning hole 6 and the second positioning hole 7; the provision of the first positioning hole 6, the second positioning hole 7 and the positioning pin ensures the positioning effect, thereby ensuring that the various holes can be aligned and ensuring the circulation effect of the coolant; the water pipe installation block 1, the water inlet block 2 and the return water block 3 are provided with threaded through holes 8 that are interconnected, and a threaded hole 81 that is connected to the threaded through hole 8 is provided on one side of the mold core 4 close to the return water block 3. A long bolt is used to pass through the threaded through hole 8 and is threadedly connected to the threaded hole 81 to complete the fixation of the overall structure, and the installation is more convenient and quick; and the provision of the threaded through hole 8 enables the bolt to be directly inserted, which is more convenient to operate;

[0031] like Figure 1-Figure 3 As shown, a sealing groove that cooperates with each other is provided between the water pipe installation block 1 and the water inlet block 2, and a sealing member 9 is embedded in the sealing groove. The sealing member 9 adopts a rubber sealing ring. A sealing groove that cooperates with each other is also provided between the water inlet block 2 and the return water block 3, and between the return water block 3 and the mold, and a sealing member 9 is also embedded therein. The setting of the sealing member 9 ensures the sealing effect of the overall structure, and prevents the coolant from leaking out, thereby affecting the cooling effect.

[0032] Working principle: The coolant is input into the first water inlet hole 11 in the water pipe mounting block 1 through the water inlet pipe 111, and enters the water inlet groove 21 on the surface of the water inlet block 2 along the first water inlet hole 11. The coolant flows into each second water inlet hole 211 along the water inlet groove 21 and enters the spot cooling needle 5. The coolant passes through the return water block 3 along the spot cooling needle 5 and enters the mold core 4. After the coolant is continuously input, the excess coolant will flow out from the spot cooling needle 5 due to the diameter of the cooling hole 42 being larger than the outer diameter of the spot cooling needle 5. The outer wall of the cold needle 5 overflows and overflows into the third water inlet hole 32 along the cooling hole 42. Since the aperture of the third water inlet hole 32 is also larger than the outer diameter of the point cold needle 5, the coolant also overflows into the return water groove 31 along the third water inlet hole 32, and then flows into the second return water hole 22 connected to the return water groove 31, and then flows into the first return water hole 12 in the water pipe mounting block 1, and is extracted through the return water pipe 121, thereby realizing the circulation effect of the coolant, thereby ensuring the point cooling effect of the overall structure.
