Description

Technical Field

[0001] This utility model relates to the field of mold casting systems, and in particular to a mold gate cooling water channel. Background Technology

[0002] Die casting is short for pressure casting. It is a method of obtaining a casting by rapidly filling the cavity of a die casting mold with molten metal (such as molten aluminum) under high pressure and solidifying it quickly under pressure. The die casting process requires a die casting mold. To prevent the molten aluminum from bursting out of the gate due to pressure loss after the mold cavity is opened, the gate needs to be cooled to a certain temperature before the mold cavity can be opened. This cooling is generally achieved through a casting sleeve.

[0003] In the prior art, the sprue sleeve and die-casting mold disclosed in patent CN218252824U, through the sprue sleeve, material sleeve, molten liquid channel, cooling tank and cooling jacket, enable water to flow in a ring, thereby allowing uniform cooling of the molten liquid channel in all directions after the flow. However, when the cooling water is added to the cooling tank through the molten liquid channel, the cooling water is not preheated. During use, the molten plastic flowing on the molten liquid channel corresponding to the inlet is easily cooled and solidified on its inner wall, which can easily obstruct the heat conduction of the subsequent water channel, affect the cooling effect, and make it inconvenient to use. In view of the shortcomings of the prior art, this utility model discloses a mold sprue cooling water channel to solve the above problems. Utility Model Content

[0004] The purpose of this application is to provide a mold gate cooling channel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a mold gate cooling channel, including a gate sleeve, a material sleeve, a cooling sleeve and a water inlet, wherein two annular plates are installed on the peripheral outer walls of the two gate sleeves, and a cleaning mechanism is provided on the two annular plates.

[0006] The cleaning mechanism includes a protective box installed on the opposite sides of the two annular plates. One of the annular plates has an clearance hole on its side that matches the protective box. A movable block is movably installed inside the protective box. Both sprue sleeves are provided with a translation and lifting assembly that moves the movable block. A fixed scraper is installed on the side of the movable block. Movable grooves are provided on the two opposite sides of the movable block. L-shaped movable plates are slidably installed on the opposite inner walls of the two movable grooves. Movable scrapers are installed on the sides of the two L-shaped movable plates. A drive assembly is provided on the movable block that moves the two L-shaped movable plates simultaneously.

[0007] Preferably, the drive assembly includes a movable cavity formed on the movable block and communicating with the two movable slots. A bidirectional lead screw is rotatably mounted on the relative inner wall of the movable cavity. One end of the bidirectional lead screw extends to the outside of the movable block and is fitted with a knob. Two movable blocks are threaded onto the bidirectional lead screw. The two L-shaped movable plates are respectively mounted on the side walls of the two movable blocks.

[0008] Preferably, the top of the movable block is provided with a threaded hole, and a fixing bolt is installed in the threaded hole. The end of the fixing bolt abuts against the bidirectional lead screw.

[0009] Preferably, the translation and lifting assembly includes two slide rods that are jointly installed on opposite sides of the two annular plates. An L-shaped slide plate is sleeved on both slide rods. A sliding hole adapted to the L-shaped slide plate is opened on the side of one of the annular plates. An elastic unit is provided on the L-shaped slide plate. A fixing block is installed on the side of the L-shaped slide plate. A lifting unit that causes the moving block to move is provided on the fixing block.

[0010] Preferably, the elastic unit includes a spring mounted on the inner wall of the side portion of the L-shaped slide plate, and the other end of the spring is mounted on the side wall of one of the annular plates.

[0011] Preferably, the side of the L-shaped skateboard is equipped with a cushioning pad.

[0012] Preferably, the lifting unit includes a fixing groove formed on the side of the fixing block, a threaded rod rotatably mounted on the inner wall of the fixing groove, the top end of the threaded rod extending to the outside of the fixing block and mounted with an adjusting plate, a threaded block threadedly sleeved on the threaded rod, a connecting block mounted on the side of the threaded block, and a moving block mounted on the side wall of the connecting block.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] In this invention, when a flow disorder or abnormality occurs, the conveying is first stopped. Then, the moving block is moved by the slide bar and L-shaped sliding plate, causing it to move out of the protective box. Next, the two moving scrapers are moved by the bidirectional screw, the movable block, and the L-shaped movable plate. When the two moving scrapers are fully extended, the fixed scraper and the moving scraper are brought into contact with the inner wall of the pouring channel by the L-shaped sliding plate, the threaded rod, the threaded block, and the connecting block. After they are in contact, the moving block is pulled again. At this time, the fixed scraper and the moving scraper will scrape the inner wall of the pouring channel, thereby scraping off the melt that is about to cool and solidify. This avoids the melt from cooling and solidifying due to prolonged neglect, which would affect the heat conduction of the subsequent water channels and facilitates use.

[0015] In this invention, the fixing bolts facilitate the fixation of the bidirectional lead screw, preventing the moving scraper from moving due to the rotation of the bidirectional lead screw during use, which would affect the scraping effect. The spring and L-shaped sliding plate facilitate the quick reset of the moving block. The buffer pad provides a certain buffering effect, reducing the vibration generated during reset.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Reference Figure 1-Figure 5The mold gate cooling channel shown includes a gate sleeve 1, a material sleeve, a cooling sleeve, and a water inlet 18. It should be noted that in this embodiment, the installation method of the gate sleeve 1, the material sleeve, the cooling sleeve, and the water inlet 18 can refer to the technical content of the gate sleeve and die casting mold disclosed in Chinese Patent No. CN218252824U in the prior art, which will not be repeated here. Two annular plates 19 are installed on the peripheral outer walls of the two gate sleeves 1, and a cleaning mechanism is provided on the two annular plates 19.

[0025] The cleaning mechanism includes a protective box 9 installed on the opposite sides of the two annular plates 19. One of the annular plates 19 has an clearance hole on its side that is adapted to the protective box 9. A movable block 10 is movably disposed inside the protective box 9. Both sprue sleeves 1 are provided with a translation and lifting assembly that moves the movable block 10. A fixed scraper 11 is installed on the side of the movable block 10. Movable grooves are provided on the two opposite sides of the movable block 10. L-shaped movable plates 14 are slidably installed on the opposite inner walls of the two movable grooves. Movable scrapers 15 are installed on the sides of the two L-shaped movable plates 14. A drive assembly is provided on the movable block 10 that moves the two L-shaped movable plates 14 simultaneously.

[0026] With the above structure, in use, the sprue sleeve 1 is first installed on the sprue, and then the molten metal is conveyed. When the hot molten metal passes through the pouring channel, the temperature inside the pouring channel rises. At this time, cooling water is injected into the inlet 18 for cooling treatment. If the flow is discontinuous or abnormal, the conveying is stopped first, and then the moving block 10 is moved by the translation and lifting assembly, thereby moving the moving block 10 out of the protective box 9. At this time, the driving assembly moves the two L-shaped movable plates 14 away from each other. The two L-shaped movable plates 14 moving away from each other will cause the two moving scrapers 15 to move. When the two When the movable scraper 15 is fully extended, the movable block 10 is lowered by the translation and lifting assembly and then enters the pouring channel. After entering, the fixed scraper 11 and the movable scraper 15 are brought into contact with the inner wall of the pouring channel. After they are in contact, the movable block 10 is pulled again. The movement of the movable block 10 will cause the fixed scraper 11 and the movable scraper 15 to move. The movement of the fixed scraper 11 and the movable scraper 15 will scrape the inner wall of the pouring channel, thereby scraping away the melt that is about to cool and solidify. This avoids the melt from cooling and solidifying due to prolonged neglect, which would affect the heat conduction of the subsequent water channels and make it easier to use.

[0027] like Figure 3 and Figure 4As shown, the drive assembly includes a movable cavity formed on the movable block 10 and communicating with the two movable slots. A bidirectional lead screw 12 is rotatably mounted on the inner wall of the movable cavity. One end of the bidirectional lead screw 12 extends to the outside of the movable block 10 and is fitted with a knob 16. Two movable blocks 13 are threaded onto the bidirectional lead screw 12. Two L-shaped movable plates 14 are respectively mounted on the side walls of the two movable blocks 13. A threaded hole is formed at the top of the movable block 10. A fixing bolt 17 is threaded into the threaded hole. The end of the fixing bolt 17 abuts against the bidirectional lead screw 12. The advantage of this arrangement is that the bidirectional lead screw 12, knob 16, movable blocks 13 and fixing bolt 17 facilitate the movement of the two L-shaped movable plates 14 away from each other.

[0028] Specifically, rotating the knob 16 will cause the bidirectional lead screw 12 to rotate. The rotation of the bidirectional lead screw 12 will cause the two movable blocks 13 to move away from or towards each other. The two movable blocks 13 moving away from or towards each other will cause the two L-shaped movable plates 14 to move away from or towards each other, which in turn will cause the two movable scrapers 15 to move away from or towards each other. This increases the scraping area during use and allows for easy storage when not in use. The fixing bolts 17 facilitate the fixing of the bidirectional lead screw 12, preventing the movable scrapers 15 from moving due to the rotation of the bidirectional lead screw 12 itself during use, thus avoiding any impact on the scraping effect.

[0029] like Figure 1 and Figure 5 As shown, the translation and lifting assembly includes two slide rods 2 jointly installed on opposite sides of the two annular plates 19. An L-shaped slide plate 3 is fitted onto both slide rods 2. One of the annular plates 19 has a sliding hole on its side that matches the L-shaped slide plate 3. An elastic unit is provided on the L-shaped slide plate 3, and a fixing block 5 is installed on its side. The fixing block 5 is equipped with a lifting unit that allows the moving block 10 to move. The elastic unit includes a spring 4 installed on the inner wall of the side of the L-shaped slide plate 3, with the other end of the spring 4 installed on the side wall of one of the annular plates 19. A buffer pad is installed on the side of the L-shaped slide plate 3. This arrangement facilitates the movement of the moving block 10 through the combination of the slide rods 2, the L-shaped slide plate 3, the fixing block 5, and the spring 4.

[0030] Specifically, sliding the L-shaped slide plate 3 will cause the fixed block 5 to move. The movement of the fixed block 5 will cause the moving block 10 to move through the lifting unit, thereby causing the fixed scraper 11 and the moving scraper 15 to move out of the protective box 9. The spring 4 is designed to make the L-shaped slide plate 3 quickly reset when it is not under force, thereby causing the moving block 10 to reset quickly. The buffer pad provides a certain buffering effect and reduces the vibration generated when the L-shaped slide plate 3 resets.

[0031] like Figure 5 As shown, the lifting unit includes a fixing groove opened on the side of the fixing block 5. A threaded rod 6 is rotatably installed on the inner wall of the fixing groove. The top end of the threaded rod 6 extends to the outside of the fixing block 5 and is equipped with an adjusting plate. A threaded block 7 is threadedly sleeved on the threaded rod 6. A connecting block 8 is installed on the side of the threaded block 7. The moving block 10 is installed on the side wall of the connecting block 8. The advantage of this arrangement is that the threaded rod 6, adjusting plate, threaded block 7, and connecting block 8 facilitate contact between the fixed scraper 11 and the moving scraper 15 and the inner wall of the pouring channel.

[0032] Specifically, the rotation of the adjusting plate causes the threaded block 7 to move, the movement of the threaded block 7 causes the connecting block 8 to move, the movement of the connecting block 8 causes the moving block 10 to move, which in turn causes the fixed scraper 11 and the moving scraper 15 to move, thereby bringing the fixed scraper 11 and the moving scraper 15 into contact with the inner wall of the pouring channel.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
