Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically a nozzle for casting molds. Background Technology

[0002] Casting molds are an important carrier of production equipment, and nozzles are key components of molds, directly affecting product quality and production efficiency. In terms of material selection, steels such as DC53 and SKD61 are widely used due to their high hardness and wear resistance, while S136 stainless steel is suitable for transparent products to achieve a mirror polishing effect. For high-wear scenarios, tungsten carbide lined nozzles can have a lifespan of up to 300 hours, while boron carbide liners can extend it to 750 hours, making them particularly suitable for sandblasting operations.

[0003] Traditional casting mold nozzles have a single sand injection channel. Due to space limitations, nozzles cannot be placed in narrow areas of the cavity, resulting in incomplete core injection in deep and narrow areas of the cavity. Therefore, a new casting mold nozzle is proposed to address the above problems. Utility Model Content

The end of the Y-shaped flow-dividing cavity extends to the bottom to form a first sand-shooting channel and a second sand-shooting channel. The sand-shooting openings of the first sand-shooting channel and the second sand-shooting channel are different in size. The flow-dividing branch of the Y-shaped flow-dividing cavity is arc-shaped.

[0007] Preferably, a connecting pipe is fixedly connected to the inner side of the injection tube, the connecting pipe is inserted into the inner side of the nozzle body, a plurality of mounting blocks are fixedly connected to the outer side of the nozzle body, a positioning groove is opened at the top of the mounting block, a plurality of locators are installed on the outer side of the injection tube, a positioning frame is fixedly connected to the bottom of the locator, and a pull ring is installed at the top of the locator.

[0012] 1. In this utility model, by setting the injection tube, the nozzle body, the Y-shaped flow divider, the first sand injection channel and the second sand injection channel, the sand injection channel can be divided into two, so that sand can be injected at multiple points and simultaneously in narrow areas.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A casting mold nozzle includes an injection tube 1 and a nozzle body 2 installed at the bottom of the injection tube 1. The nozzle body 2 has a Y-shaped flow divider 3 inside. The end of the Y-shaped flow divider 3 extends to the bottom to form a first sand injection channel 4 and a second sand injection channel 5. The sand injection openings of the first sand injection channel 4 and the second sand injection channel 5 are different in size. The flow divider of the Y-shaped flow divider 3 is arc-shaped. By setting the injection tube 1, nozzle body 2, Y-shaped flow divider 3, first sand injection channel 4 and second sand injection channel 5, the sand injection channel can be divided into two, so that multiple points can be shot synchronously in narrow areas. The arc-shaped flow divider of the Y-shaped flow divider 3 is conducive to sand flow and avoids dead corners in the cavity or loose sand core caused by single-sided sand injection. Compared with the existing design, it can maximize the use of limited space, arrange the nozzle in the deep and narrow part of the mold, realize synchronous sand injection on both sides of the narrow part, and effectively avoid incomplete sand core injection.

[0025] A connecting pipe 6 is fixedly connected to the inner side of the injection tube 1. The connecting pipe 6 is inserted into the inner side of the nozzle body 2. Multiple mounting blocks 7 are fixedly connected to the outer side of the nozzle body 2. The top of the mounting block 7 has a positioning groove 8. Multiple positioners 9 are installed on the outer side of the injection tube 1. The bottom of the positioner 9 is fixedly connected to a positioning frame 91. A pull ring 11 is installed on the top of the positioner 9. The positioner 9 includes a positioning frame 91 fixedly connected to the outer side of the injection tube 1. A sliding plate 92 is slidably connected to the inner side of the positioning frame 91. A connecting rod 93 is fixedly connected to the top of the sliding plate 92. A positioning spring 94 is provided on the outer side of the connecting rod 93. A positioning pin 95 is fixedly connected to the bottom of the sliding plate 92. The connecting rod 93 passes through the positioning frame 91 and is slidably connected to the positioning frame 91. The top of the connecting rod 93 is fixedly connected to the pull ring 11. The positioning pin 95 passes through the positioning frame 91 and the mounting frame 10 and is fixedly connected to the pull ring 11. The mounting frame 10 is slidably connected. One end of the positioning spring 94 is fixedly connected to the slide plate 92, and the end of the positioning spring 94 away from the slide plate 92 is fixedly connected to the inner side of the positioning frame 91. The mounting block 7 is set inside the mounting frame 10, and the positioning pin 95 is inserted into the inner side of the positioning groove 8. Through the connecting pipe 6, mounting block 7, positioning groove 8, locator 9, mounting frame 10 and pull ring 11, when installing the nozzle body 2, the connecting pipe 6 is inserted into the inner side of the nozzle body 2 and the pull ring 11 is pulled to move the positioning pin 95. Then, the nozzle body 2 is rotated to move the mounting block 7 to the inner side of the mounting frame 10 and the pull ring 11 is released to move the positioning pin 95 to the inner side of the positioning groove 8, thus completing the installation of the nozzle body 2. This design allows the nozzle body 2 to be replaced as needed, thereby adjusting the size of the first sand-shooting channel 4 and the second sand-shooting channel 5.

[0026] Workflow: When the device is needed, install the injection tube 1 onto the sand-shooting plate, then install the nozzle body 2. Place the nozzle body 2 on one side of the injection tube 1, inserting the connecting tube 6 into the inside of the nozzle body 2. Then pull the pull ring 11, which moves the connecting rod 93. The slide plate 92 slides inside the positioning frame 91, and the positioning pin 95 slides inside the positioning frame 91 and the mounting frame 10. The positioning spring 94 is compressed. At this time, rotate the nozzle body 2 to move the mounting block 7 inside the mounting frame 10. Then release the pull ring 11 to reset the positioning spring 94 and move the connecting rod 93. The slide plate 92 slides inside the positioning frame 91, and the positioning pin 95 slides inside the positioning frame 91 and the mounting frame 10 until the positioning pin 95 is inserted into the positioning groove 8 on the mounting block 7. The nozzle body 2 can be installed from the side. With this design, the sand injection channel can be divided into two, so that the end of the Y-shaped flow chamber 3 extends to the bottom of the nozzle body 2 to form the first sand injection channel 4 and the second sand injection channel 5. This allows for multi-point and synchronous sand injection in narrow areas. The flow branch of the Y-shaped flow chamber 3 is arc-shaped, which is conducive to sand flow and avoids dead corners in the cavity or loose sand core caused by single-sided sand injection. Compared with the existing design, it can maximize the use of limited space, arrange the nozzle in the deep and narrow part of the mold, and realize synchronous sand injection on both sides of the narrow part, effectively avoiding incomplete sand core injection. The design of the positioner 9 and its connecting components can replace the nozzle body 2 as needed, thereby adjusting the size of the first sand injection channel 4 and the second sand injection channel 5.
