Description

Technical Field

[0001] This utility model relates to the field of die casting machine technology, and in particular to a quick mold adjustment device for die casting machines. Background Technology

[0002] A die-casting machine is a machine used for pressure casting. It includes two types: hot-chamber and cold-chamber. The latter is further divided into vertical and horizontal types. Under pressure, the die-casting machine injects molten metal into a mold to cool and solidify. After the mold is opened, a solid metal casting is obtained. Because the molds used in the die-casting process are not all the same, with differences in size and thickness, a mold-adjusting device needs to be installed in the die-casting machine to adjust the distance between the moving mold and the stationary mold.

[0003] Currently, a Chinese patent discloses a die-casting machine mold adjustment device and a die-casting machine using the same (authorization announcement number CN211638277U). This utility model includes a base, a driving component mounted on the base, a first gear, and several mold adjustment units. The first gear is rotatably mounted on the base, and the driving end of the driving component meshes with the first gear. The mold adjustment unit includes a second gear and a guide post. The second gear is rotatably mounted on the base, and the first gear meshes with the second gear. The second gear has a mounting hole, and the guide post passes through the mounting hole and meshes with the second gear through a threaded structure, so that the base can move relative to the guide post, which greatly saves space. Furthermore, by utilizing the cooperation of the first gear and the second gear, multiple mold adjustment units can be driven to operate simultaneously, further saving space. However, the above method has the following drawbacks in actual use: the gear ratio between the first gear and the second gear is fixed, and the mold adjustment speed can only be adjusted by changing the rotation speed of the driving mechanism, which is relatively slow.

[0028] The following is combined Figures 1-4 This invention describes a rapid mold adjustment device for a die-casting machine.

[0029] In one embodiment, a quick mold adjustment device for a die-casting machine includes: a guide rod 110, a base 100 threadedly connected to the guide rod 110, a mold adjustment mechanism 200 provided on the base 100, the mold adjustment mechanism 200 including a hydraulic telescopic rod 210 fixedly connected to the base 100, a hydraulic motor 211 fixedly connected to the telescopic end of the hydraulic telescopic rod 210, a large drive gear 212 and a small drive gear 213 fixedly connected to the output shaft of the hydraulic motor 211 respectively, a large driven gear 215 rotatably connected to one side of the base 100, a small driven gear 214 fixedly connected to the surface of the large driven gear 215, a connecting gear 216 meshing with the large driven gear 215 fixedly connected to one end of the guide rod 110, and a lubrication mechanism 300 for lubricating the gears.

[0030] like Figure 3 As shown, the small driven gear 214 is correspondingly set to the large driving gear 212, the large driven gear 215 is correspondingly set to the small driving gear 213, and the small driven gear 214 and the large driving gear 212 are staggered.

[0031] In this embodiment, when mold adjustment is required, the hydraulic telescopic rod 210 is activated, causing the large drive gear 212 to mesh with the small driven gear 214. Under the action of the hydraulic motor 211, the large drive gear 212 drives the small driven gear 214 to rotate. The rotation of the small driven gear 214 drives the large driven gear 215 to rotate, thereby causing the connecting gear 216 to rotate synchronously. This causes the base 100 to move along the guide rod 110, making the moving mold on the base 100 move closer to or away from the stationary mold. When the moving mold and the stationary mold approach the set distance, the hydraulic motor 211 extends, causing the small drive gear 213 to mesh with the large driven gear 215, switching to low-speed mode, and precisely adjusting the distance between the moving mold and the stationary mold, ensuring both the speed and accuracy of mold adjustment.

[0032] In this embodiment, the hydraulic motor 211 is configured as a brake hydraulic motor. After the mold adjustment is completed, the hydraulic motor 211 is locked, thereby fixing the distance between the moving mold and the stationary mold.

[0033] like Figure 2 As shown, a limiting groove 217 is provided on the base 100, and a limiting block 218 is slidably connected in the limiting groove 217. The output shaft end of the hydraulic motor 211 is rotatably connected to one side of the limiting block 218. The size of the limiting block 218 is larger than the size of the small drive gear 213.

[0034] In this embodiment, the limiting block 218 is limited by the limiting groove 217, and the limiting block 218 and the hydraulic telescopic rod 210 ensure the stability of the hydraulic motor 211 during rotation. When the hydraulic telescopic rod 210 switches to high-speed mode, the limiting block 218 moves into the limiting groove 217, causing the small drive gear 213 to enter the limiting groove 217. At this time, the small driven gear 214 meshes with the large drive gear 212.

[0035] like Figure 1 and Figure 4 As shown, the lubrication mechanism 300 includes an oil tank 310 fixedly connected to the base 100, with an oil drip pipe 312 fixedly connected to the bottom of the oil tank 310. A valve 311 is fixedly installed on the oil drip pipe 312, and an oil filling port is provided on the top of the oil tank 310. There are two oil drip pipes 312, one located directly above the large driven gear 215 and the other located directly above the small driven gear 214.

[0036] In this embodiment, lubricating oil is added to the oil tank 310 through the oil filling port. When adjusting the mold, the valve 311 is opened, and the lubricating oil in the oil tank 310 drips onto the corresponding gear through the oil dripping pipe 312 to lubricate the gear. In high-speed mode, the small driven gear 214 is lubricated, and in low-speed mode, the large driven gear 215 is lubricated. By lubricating the gears, wear is reduced and the accuracy of mold adjustment is improved.

[0037] like Figure 3 As shown, the large drive gear 212 and the small drive gear 213 have the same axis, and the distance between the large drive gear 212 and the small drive gear 213 is greater than the thickness of the small driven gear 214.

[0038] In this embodiment, the speed of mold adjustment is adjusted by switching different gear meshing. In low speed mode, the small drive gear 213 meshes with the large driven gear 215. At this time, since the distance between the large drive gear 212 and the small drive gear 213 is greater than the thickness of the small driven gear 214, the small driven gear 214 does not contact the hydraulic telescopic rod 210, thus avoiding mutual interference of gears when switching modes.

[0039] Working principle: The hydraulic telescopic rod 210 drives the hydraulic motor 211 to move, thereby changing the position of the large drive gear 212 and the small drive gear 213, switching different gear meshing, and thus adjusting the mold adjustment speed. Initially, the large drive gear 212 is switched to mesh with the small driven gear 214, which increases the speed of the large driven gear 215, thereby increasing the displacement speed of the base 100. After approaching the set mold adjustment distance, the small drive gear 213 is switched to mesh with the large driven gear 215, which reduces the speed of the large driven gear 215, causing the base 100 to move slowly and improving the mold adjustment accuracy.

[0040] It should be noted that the hydraulic motor 211, hydraulic telescopic rod 210, valve 311, etc. mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
