Description

Technical Field

[0001] This utility model relates to the field of die casting manufacturing technology, and in particular to a venting block mounting structure for a die casting mold. Background Technology

[0002] In die-casting molds, venting blocks are primarily used to release gases from the mold, thereby reducing or eliminating bubbles and porosity generated during the die-casting process, thus improving the quality and surface finish of the castings. After prolonged use, aluminum may adhere to the venting blocks on the die-casting machine, obstructing the release of gases. Therefore, the venting blocks need to be replaced, meaning the aluminum-adhered venting blocks need to be removed from the mold. However, currently, removing venting blocks is quite cumbersome, requiring the mold frame to be disassembled first, followed by the removal and replacement of the venting blocks. This operation is cumbersome, time-consuming, and labor-intensive, resulting in high time costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a simple venting block mounting structure for die casting molds, which can realize the quick disassembly and replacement of venting blocks.

One end of the fixed mold venting block is fixedly connected to the fixed mold core, and the other end of the fixed mold venting block is limited by the first limiting block.

[0010] The fixed mold venting block has a first positioning protrusion protruding in the direction of the first limiting block, and the first limiting block has a corresponding first positioning groove that cooperates with the first positioning protrusion. The first positioning protrusion is embedded in the first positioning groove.

[0011] The moving mold frame is detachably provided with a second limiting block, and the moving mold venting block is disposed between the second limiting block and the moving mold core. One end of the moving mold venting block is fixedly connected to the moving mold core, and the other end of the moving mold venting block is limited by the second limiting block.

[0012] The moving mold exhaust block has a second positioning protrusion protruding in the direction of the second limiting block, and the second limiting block has a corresponding second positioning groove that cooperates with the second positioning protrusion. The second positioning protrusion is embedded in the second positioning groove.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] As shown in the figure, a venting block mounting structure for a die casting mold includes a mold body and a venting block body. The mold body includes a fixed mold frame 1 and a moving mold frame 2. The fixed mold frame 1 is provided with a fixed mold core 11, and the moving mold frame 2 is provided with a moving mold core 21. The venting block body includes a fixed mold venting block 3 for fixed installation with the fixed mold core 11 and a moving mold venting block 4 for fixed installation with the moving mold core 21. After the moving mold core 21 and the fixed mold core 11 are closed, a mold cavity is formed (not shown in the figure), which drives the fixed mold venting block 3 and the moving mold venting block 4 to close and form a corresponding venting channel 304.

[0022] The fixed mold venting block 3 has a first mounting hole 31 that passes through the side of the fixed mold core 11. The side of the fixed mold core 11 is provided with a first internal thread mounting hole 111 that mates with the first mounting hole 31. The fixed mold venting block 3 and the fixed mold core 11 are fixedly installed by the rod of the first mounting bolt 5 that mates with the first internal thread mounting hole 111 passing through the first mounting hole 31 and being screwed into the first internal thread mounting hole 111. The moving mold venting block 4 has a second mounting hole 41 that passes through the side of the moving mold core 21. The side of the moving mold core 21 is provided with a second internal thread mounting hole 211 that mates with the second mounting hole 41. The moving mold venting block 4 and the moving mold core 21 are fixedly installed by the rod of the second mounting bolt 6 that mates with the second internal thread mounting hole 211 passing through the second mounting hole 41 and being screwed into the second internal thread mounting hole 211.

[0023] The fixed mold frame 1 has a through fixed mold mounting cavity 10 corresponding to the mounting position of the fixed mold venting block 3, and the fixed mold venting block 3 is embedded in the fixed mold mounting cavity 10; the moving mold frame 2 has a through moving mold mounting cavity 20 corresponding to the mounting position of the moving mold venting block 4, and the moving mold venting block 4 is embedded in the moving mold mounting cavity 20.

[0024] In this specific embodiment, the first mounting hole 31 includes a first through-joint section 311 coaxially arranged for the shank of the first mounting bolt 5 to pass through and for installation, and a first limiting section 312 for the head of the first mounting bolt 5 to be embedded and limited for installation, with the head of the first mounting bolt 5 embedded within the first limiting section 312; the second mounting hole 41 includes a second through-joint section 411 coaxially arranged for the shank of the second mounting bolt 6 to pass through and for installation, and a second limiting section 412 for the head of the second mounting bolt 6 to be embedded and limited for installation, with the head of the second mounting bolt 6 embedded within the second limiting section 412. This achieves concealed installation of the mounting bolts, resulting in a neat and compact overall structure.

[0025] In this specific embodiment, a first limiting block 7 is detachably provided on the fixed mold frame 1, and a fixed mold venting block 3 is disposed between the first limiting block 7 and the fixed mold core 11. One end of the fixed mold venting block 3 is fixedly connected to the fixed mold core 11, and the other end of the fixed mold venting block 3 is limited by the first limiting block 7. A second limiting block 8 is detachably provided on the moving mold frame 2, and a moving mold venting block 4 is disposed between the second limiting block 8 and the moving mold core 21. One end of the moving mold venting block 4 is fixedly connected to the moving mold core 21, and the other end of the moving mold venting block 4 is limited by the second limiting block 8. The limiting blocks are used to ensure that the corresponding venting blocks will not be displaced during the production process, preventing the venting blocks from failing due to positional displacement caused by changes in force, and ensuring that the venting blocks can function stably.

[0026] In this specific embodiment, the fixed mold venting block 3 has a first positioning protrusion 32 protruding towards the first limiting block 7, and the first limiting block 7 has a corresponding first positioning groove 71 that cooperates with the first positioning protrusion 32.

The second positioning protrusion 42 is embedded in the second positioning groove 81. Through the cooperation of the positioning protrusion and the positioning groove, precise positioning is achieved, avoiding the functional failure caused by the venting block swaying left and right due to changes in force during the production process, and ensuring that the venting block can function stably.

[0027] In this specific embodiment, the internal water passage of the exhaust block and the vacuum pump can be connected to the outside by passing through the corresponding limiting baffle.

[0028] When it is necessary to remove the exhaust block body, simply remove the first limit block 7 and the second limit block 8 from the corresponding mold frame, and then loosen the corresponding mounting bolts.
