Description

A multi-cavity casting trimming device

Technical Field

The utility model relates to the technical field of casting processing, in particular to a multi-cavity casting trimming device.

Background Art

Multi-cavity casting is a type of metal casting process that saves production time and cost by casting multiple components simultaneously in a mold with multiple molding cavities. Multi-cavity castings usually consist of a sprue and multiple workpieces. The multiple workpieces are formed in multiple molding cavities in the mold, and the sprue is formed in a channel in the mold for supplying molten metal flow. After the multi-cavity casting is cast, the multiple workpieces are connected to the sprue. At this time, the multiple workpieces need to be trimmed by a trimming mold so that the multiple workpieces are disconnected from the sprue, thereby obtaining multiple finished workpieces.

Since the size and appearance of the newly cast multi-cavity castings are unstable, it is easy to cause the lower surfaces of multiple workpieces (the lower surface of the workpiece is the surface in contact with the positioning structure in the trimming mold) to be unable to be in the same horizontal plane, which in turn causes the multiple workpieces to be unable to be accurately positioned in the trimming mold at the same time, which not only reduces the accuracy of trimming, but also reduces the yield rate of the finished workpieces. In order to ensure the yield rate of the finished workpieces, in the prior art, the operator first separates the multiple workpieces from each other through the rough trimming mold, and then uses the fine trimming mold to cut off the remaining sprues on the multiple workpieces in turn to obtain multiple finished workpieces. This method of performing trimming twice through two trimming molds is not conducive to the large-scale production of finished workpieces and reduces the manufacturing efficiency of finished workpieces.

Utility Model Content

As the bottom plate 100 rises, the workpiece pushing assembly 700 pushes the multiple workpieces, so that the multiple workpieces are pressed and fixed on the workpiece positioning assembly 400, and the lower surfaces of the multiple workpieces are all on the same horizontal plane. Finally, the bottom plate 100 continues to rise, and the cutting end of the cutting assembly 500 abuts against the connection between the nozzle and the multiple workpieces, and the connection between the nozzle and the multiple workpieces is cut off at the same time to obtain a finished workpiece. In the multi-cavity casting trimming device of the embodiment of the utility model, the nozzle push assembly 600 first pushes the nozzle of the multi-cavity casting, so that the nozzle is accurately positioned on the nozzle positioning assembly 300; then the workpiece push assembly 700 pushes the multiple workpieces of the multi-cavity casting, so that the lower surfaces of the multiple workpieces are all on the same horizontal plane, so that the multiple workpieces can be accurately positioned on the workpiece positioning assembly 400 at the same time; finally, when the nozzle and the multiple workpieces are accurately positioned, the cutting assembly 500 is used to simultaneously cut off the connection between the nozzle and the multiple workpieces.

It is understandable that under the action of the workpiece pushing assembly 700, the first spring 420 compresses and makes the workpiece positioning block 410 have a tendency to move upward, thereby increasing the pressure between the workpiece positioning block 410 and the workpiece, thereby increasing the accuracy of the workpiece positioning block 410 in positioning the workpiece. As an embodiment of the utility model, the workpiece positioning block 410 is provided with a first guide column 430 parallel to the up and down direction, and the bottom plate 100 is provided with a first guide hole, and the first guide column 430 is penetrated in the first guide hole.

It can be understood that the cutting ends of the plurality of cutting blocks 510 are the cutting ends of the cutting assembly 500. In the process of the lifting drive assembly 110 driving the bottom plate 100 to rise, the cutting ends of the plurality of cutting blocks 510 first abut against the connection between the plurality of workpieces and the water outlet, and as the bottom plate 100 continues to rise, the cutting ends of the plurality of cutting blocks 510 respectively cut off the connection between the plurality of workpieces and the water outlet, thereby causing the plurality of workpieces to detach from the water outlet. The cutting edge of the cutting block 510 is the cutting end of the cutting block 510.

The plurality of third springs 720 are compressed to cause the plurality of workpiece pushing blocks 710 to rise, and cause the cutting ends of the plurality of cutting blocks 510 to respectively cut off the connection between the plurality of workpieces and the water outlet. It can be understood that, during the process of the lifting drive assembly 110 driving the bottom plate 100 and the multi-cavity casting on the bottom plate 100 to rise, the multiple workpieces on the multi-cavity assembly will first extend into the lower ends of the guide holes 511 on the multiple cutting blocks 510 respectively; then, as the multiple workpieces continue to rise, the multiple workpieces will respectively abut against the lower surfaces of the multiple workpiece push blocks 710; the multiple workpieces continue to rise, the multiple third springs 720 are compressed, and under the elastic force of the multiple third springs 720, the multiple workpiece push blocks 710 push the multiple workpieces from top to bottom respectively, so that the multiple workpieces can be pressed against the multiple workpiece positioning blocks 410 respectively, and the lower surfaces of the multiple workpieces are all on the same horizontal plane.

It can be understood that in the process of the multi-cavity casting rising, since the bottom surface of the push posts 610 is arranged below the lower surface of the workpiece push block 710, the nozzles in the multi-cavity casting will first abut against the bottom surfaces of the plurality of push posts 610, and the nozzles continue to rise, and the plurality of fourth springs 620 are compressed. Under the elastic force of the plurality of fourth springs 620, the plurality of push posts 610 push the nozzles from top to bottom, so that the nozzles can be pressed against the inner walls of the nozzle positioning grooves 311 of the plurality of nozzle positioning blocks 310, so that the nozzles can be accurately positioned. After the fourth springs 620 are compressed to a certain extent, the lower surfaces of the workpiece pushing blocks 710 will respectively contact the workpieces.
