Description

Technical Field

[0001] The utility model belongs to the technical field of blanking manipulators, and in particular relates to a blanking mechanism for an automobile die-casting mold. Background Art

[0002] Die-casting molds are used in the production of automotive parts. They are tools that complete the die-casting process on a special die-casting forging machine. The molten metal is first cast and filled into the cavity of the mold at a low or high speed. The mold has a movable cavity surface. It is pressurized and forged as the molten metal cools, which not only eliminates the shrinkage defects of the blank, but also makes the internal structure of the blank reach the broken grains in the forged state. After the parts are cast, the parts in the die-casting mold will be removed by a blanking robot. Chinese patent application number 202123162298.0 discloses a blanking robot for die-casting molds. It can be seen that the content describes a blanking mechanism for an automotive die-casting mold.

[0003] When the existing unloading mechanism of the automobile die-casting mold is in use, the parts in the die-casting mold are clamped and taken out by two sets of clamping claws on the unloading robot. However, the clamping claws can only clamp and take out parts of a certain size. When clamping larger parts in some die-casting molds, it is necessary to replace clamping claws of other sizes. This reduces the applicability of the clamping claws and also requires preparing multiple clamping claws of different sizes, which increases the cost of use. For this reason, we propose a unloading mechanism for the automobile die-casting mold. Utility Model Content

[0004] The purpose of the utility model is to provide a blanking mechanism for an automobile die-casting mold, so as to solve the problem that when the existing blanking mechanism for an automobile die-casting mold is used, when clamping some larger-sized parts in the die-casting mold, it is necessary to replace the clamping claws with other sizes, which reduces the applicability of the clamping claws.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding mechanism for an automobile die-casting mold, comprising a mechanical arm, a clamping cylinder and two groups of clamping claws, the clamping claws comprising an upper claw and a lower claw, an arc-shaped plate is fixedly provided on the lower claw, an adjustment mechanism is provided between the lower claw and the upper claw, the adjustment mechanism comprises a horizontal plate and a vertical stud, a horizontal groove is provided inside the horizontal plate, the top of the vertical stud passes through the inside of the horizontal groove, a vertical groove is provided inside the vertical stud, and a horizontal stud is provided inside the vertical groove.

[0006] Preferably, a side plate is fixedly provided on one side of the lower claw, and the end of the transverse stud is fixed on the side plate.

[0007] Preferably, two sets of nuts are arranged outside the vertical studs, and the nuts are located at the top and bottom of the horizontal plate.

[0008] Preferably, two groups of internal threaded rings are arranged on the outside of the horizontal stud, and the internal threaded rings are located on two side surfaces of the vertical stud.

[0009] Preferably, the transverse plate is fixed on the upper claw, and the lower claw is located below the upper claw.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-Figure 3 The utility model provides a technical solution: a material discharging mechanism of an automobile die-casting mold, comprising a mechanical arm 101, a clamping cylinder 103 and two groups of clamping claws. When in use, the clamping cylinder 103 can drive the two groups of clamping claws to move left and right. The clamping claws include an upper claw 104 and a lower claw 105. An arc plate 106 is fixedly arranged on the lower claw 105. An adjustment mechanism is arranged between the lower claw 105 and the upper claw 104. The adjustment mechanism includes a horizontal plate 200 and a vertical stud 201. When in use, the horizontal plate 200 is fixed on the upper claw 104. A horizontal groove 202 is provided inside the horizontal plate 200. The top of the vertical stud 201 passes through the inside of the horizontal groove 202. A vertical groove 206 is provided inside the vertical stud 201. A horizontal stud 204 is arranged inside the vertical groove 206. When in use, the horizontal stud 204 is connected to the internal threaded ring 205 by screw thread engagement. A side plate 207 is fixed on the side, and the end of the horizontal stud 204 is fixed on the side plate 207. Two groups of nuts 203 are arranged on the outside of the vertical stud 201. When in use, the nuts 203 are screwed together with the horizontal and vertical studs 201 through threads. The nuts 203 are located at the top and bottom of the horizontal plate 200, and two groups of internal threaded rings 205 are arranged on the outside of the horizontal stud 204. The internal threaded rings 205 are located on both sides of the vertical stud 201. The horizontal plate 200 is fixed on the upper claw 104, and the lower claw 105 is located below the upper claw 104. Through the designed adjustment mechanism, when larger-sized parts in the die-casting mold are unloaded and removed during use, the lower claw 105 can be moved outward and downward, thereby increasing the spacing between the two groups of arc plates 106, so that the two groups of clamping claws can clamp larger-sized parts for removal, thereby improving the applicability of the unloading robot.

[0021] In this embodiment, preferably, connecting plates 300 are fixedly provided on the front and back sides of the arc plate 106, and the connecting plate 300 is fixedly connected to the lower claw 105 by bolts. The connecting plate 300 can be disassembled and assembled by bolts during use. By combining the designed connecting plate 300 and bolts, the inner wall of the arc plate 106 on the clamping claw contacts with parts during use, and the inner wall of the arc plate 106 is worn over time. The worn arc plate 106 can be replaced, which improves the use effect.

[0022] In this embodiment, preferably, a mounting head 102 is provided on the robot arm 101 , and a movable arm 100 is provided at the bottom of the robot arm 101 .

[0023] The working principle and use process of this utility model:

[0024] When the utility model is in use, when taking out the larger-sized parts in the die-casting mold, first loosen the two sets of nuts 203, and then move the vertical stud 201 outward, then the vertical stud 201 slides in the horizontal groove 202, driving the lower claw 105 and the arc plate 106 to move, and then stop moving after moving to a suitable position, and then tighten the two sets of nuts 203 to fix the vertical stud 201, and then unscrew the two sets of internal threaded rings 205, and then the lower claw 10 5 moves downward, driving the arc plate 106 and the horizontal stud 204 to move. At this time, the horizontal stud 204 slides in the vertical slot 206, and then the lower claw 105 moves downward to a suitable position and stops moving. Finally, the two sets of internal thread rings 205 are tightened. At this time, the distance between the two sets of lower claws 105 can be increased, so that the clamping claws can clamp and remove parts of larger sizes. When taking out parts of normal sizes, the lower claws 105 can be restored to their original positions according to the reverse principle mentioned above;

[0025] When replacing the worn arc plate 106 during use, the bolts on the connecting plate 300 are unscrewed to remove the arc plate 106 for replacement.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
