Description

Technical Field

[0001] The utility model relates to the technical field of blanking equipment, in particular to a material taking fixture for injection molding blanking equipment. Background Art

[0002] Injection molded parts refer to products that are processed by an injection molding machine by molding molten plastic or silicone rubber materials through a mold. When demolding the mold after injection molding, the injection molded product still has a high temperature, generally up to several dozen degrees. Therefore, it is often dangerous to remove the molded injection molded product from the mold. Larger products are easier to demold, while smaller products tend to stick to the mold and are not easy to demold. Manual operation is often required. Due to the high temperature of the injection molded product, the operator needs to wear certain protective gear to operate it to avoid being burned by high temperature. This also leads to the fact that the efficiency of manual unloading cannot be improved. At the same time, working in a high temperature environment increases the labor intensity of the operator.

[0003] At present, a material picking device is usually provided in the unloading equipment of the injection molding machine to remove the workpiece completed by the injection molding machine. However, for some workpieces, higher precision is required during the material picking process. Otherwise, the material picking device and the workpiece cannot be accurately aligned, so that the workpiece cannot be stably clamped or adsorbed, and the material cannot be picked up stably and accurately.

[0004] Therefore, there is an urgent need for a material removal device for injection molding unloading equipment, which can accurately and stably remove the injection molded workpiece. Utility Model Content

The present invention is described in detail below in conjunction with the drawings.

[0039] The embodiment of the utility model provides a material picking fixture for injection molding unloading equipment, which is provided with a compensation device 200, and can compensate for the position of a pneumatic clamp 310 used to grab the injection molded product. Specifically, since the fixture has a certain inclination angle with the injection mold during the process of grabbing the injection molded product, and thus cannot be aligned with the injection molded product, the compensation device 200 can supplement the inclination angle of the pneumatic clamp 310 relative to the injection mold, so that the position of the pneumatic clamp 310 can be adjusted to be parallel to the mold, so that the material can be picked up accurately.

[0040] In this embodiment, if Figure 1-9 As shown, this embodiment provides a material picking fixture for injection molding unloading equipment, including a mounting seat 100, a compensation device 200 and a mounting plate 300, wherein the compensation device 200 is fixedly mounted on the mounting seat 100, and the compensation device 200 includes a base plate 201 and a movable component 210, the base plate 201 is fixedly mounted on the mounting seat 100, and an adjusting cylinder 202 is installed at two corresponding edges of the base plate 201, and the movable component 210 includes a compensation shaft 211 in the middle, the compensation shaft 211 is movably connected to the middle of the base plate 201, and the piston rod of the adjusting cylinder 202 is in contact with the movable component 210; the mounting plate 300 is fixedly mounted on the movable component 210, and at least one pneumatic clamp 310 is mounted on the mounting plate 300.

[0041] During the material picking process, the adjusting cylinder 202 pushes the movable component 210 so that the compensation shaft 211 can swing along the surface of the spherical sliding bearing 213 until the mounting plate 300 and the surface of the mold are parallel to each other, so that the pneumatic clamp 310 can be aligned with the injection molded product on the mold, and the injection molded product can be accurately grasped.

[0042] The embodiment of the utility model adjusts the swing position of the movable component 210 by adjusting the cylinder 202, thereby adjusting and compensating the inclination angle between the mounting plate 300 and the mold, so that the mounting plate 300 and the pneumatic clamp 310 located thereon can be aligned with the injection molded product on the mold, ensuring that the injection molded product can be accurately grasped.

[0043] In this embodiment, the movable component 210 also includes a connecting plate 212 and a fixed plate 214, wherein the connecting plate 212 is fixedly connected to the mounting plate 300, and the compensation shaft 211 is fixedly mounted on the surface of the connecting plate 212 away from the mounting plate 300, and a spherical sliding bearing 213 is fixedly mounted on the compensation shaft 211; the fixed plate 214 is fixedly mounted on the base plate 201, and a mounting hole 215 is opened on the fixed plate 214 for mounting the spherical sliding bearing 213 therein.

At the same time, the spherical sliding bearing 213 is fixedly assembled on the compensation shaft 211, and the fixed plate 214 is fixedly installed on the base plate 201. The compensation shaft 211 equipped with the spherical sliding bearing 213 is placed in the mounting hole 215, and the outer ball of the spherical sliding bearing 213 is fixedly set in the mounting hole 215. At this time, the compensation shaft 211 and the connecting plate 212 can swing with the spherical sliding bearing 213 as the origin. The connecting plate 212 is fixedly connected to the mounting plate 300, so that when the adjusting cylinder 202 pushes the connecting plate 212, the connecting plate 212 and the mounting plate 300 can swing along the spherical sliding bearing 213 as the origin, so that the inclination of the mounting plate 300 can be adjusted and swung, and it is adjusted to a state of being aligned and parallel with the mold.

[0045] In this embodiment, in order to make the spherical sliding bearing 213 more stably located within the compensation shaft 211 and the mounting hole 215, a gasket 216 is fixedly provided at the end of the compensation shaft 211, and the diameter of the gasket 216 is larger than the diameter of the prime spherical sliding bearing 213; at the same time, a bearing 213 end cover 217 is fixedly installed on the fixing plate 214, and the bearing 213 end cover 217 is used to limit the bearing 213 within the mounting hole 215.

[0050] In this embodiment, if Figure 7-9 As shown, a specific structural example of the pneumatic clamp 310 is given. The pneumatic clamp 310 includes a bidirectional cylinder 311. The piston rods of the bidirectional cylinder 311 are connected to clamping arms 312. The two clamping arms 312 move toward each other to clamp or release the material.

[0052] During the process of grabbing the injection molded product, the auxiliary cylinder 314 drives the auxiliary plate 315 to move toward the injection molded product and adsorbs the product through the suction nozzle 316. At the same time, the clamping arms 312 move toward each other under the drive of the two-way cylinder 311, thereby clamping the injection molded product, so that the material can be stably grasped under the dual effects of clamping and adsorption, thereby improving the stability of material collection and unloading of injection molded products, and effectively avoiding the falling of injection molded products due to the vibration of equipment operation during the transportation of injection molded products.

[0053] In order to facilitate the accurate docking of the material taking device and the mold of the injection molding machine, at least two pin columns 301 are fixedly installed on the mounting plate 300. The pin columns 301 are arranged at equal intervals, and the length of the pins extending from the mounting plate 300 is greater than the length of the pneumatic clamp 310 extending from the surface of the mounting plate.
