Description

Technical Field

[0001] The present invention belongs to the technical field of metal processing, and particularly relates to a metal processing casting device. Background Art

[0002] Patent Application No. CN202022250897.7 discloses a labor-saving aluminum-zinc alloy metal casting device, including a casting vehicle body. The casting vehicle body is in a cubic structure. Openings are provided on the left side wall and the top end of the casting vehicle body. The inner front wall and the inner rear wall of the casting vehicle body are both rotatably connected to a rotating shaft rod through bearings. A ladle is fixedly connected to the opposite ends of the two rotating shaft rods. Tooth-like projections are equidistantly fixedly connected to the outer surface of the ladle. A lead screw is rotatably connected to the inner left wall of the casting vehicle body through a bearing. The lead screw meshes with the tooth-like projections. A reduction motor is fixedly connected to the inner bottom wall of the casting vehicle body. However, the disadvantage of this technical solution is that it is impossible to cut off the metal liquid flow, which easily causes excessive injection of the metal liquid flow. Summary of the Invention

[0003] The purpose of the present invention is to provide a metal processing casting device to solve the technical problem that it is impossible to cut off the metal liquid flow, which easily causes excessive injection of the metal liquid flow.

[0004] To achieve the above purpose, the specific technical solution of a metal processing casting device of the present invention is as follows:

[0005] A metal processing casting device, comprising a box body, a rectangular opening, a first positioning card slot, a slide plate, a handwheel, a threaded rotating rod, a contact plate, an upper end cover, a connecting pipe, a feeding sleeve, a first connecting frame, a spring, a slide rod, a partition slide rod, a second connecting frame, a middle-end mold, a floating rod, a second positioning clamping rod, a second positioning push spring, a rotating gear, a first positioning clamping rod, a first positioning push spring, and a second positioning card slot. A rectangular opening is formed in the box body, and a slide plate is slidably installed in the rectangular opening. A threaded rotating rod is threadedly installed on the slide plate. One end of the threaded rotating rod is fixedly installed with a handwheel, and the other end of the threaded rotating rod is fixedly installed with a contact plate. A first positioning card slot is formed in the rectangular opening, and a plurality of first positioning card slots are provided. A second positioning clamping rod is slidably installed on the slide plate. A second positioning push spring is arranged between the second positioning clamping rod and the slide plate. The second positioning clamping rod is in mating connection with the first positioning card slot. A second positioning card slot is formed in the box body. A connecting pipe is fixedly installed on the upper end cover. A second positioning clamping rod is slidably installed in the connecting pipe. A second positioning push spring is arranged between the second positioning clamping rod and the connecting pipe. The second positioning clamping rod is in mating connection with the second positioning card slot to realize the connection between the box body and the upper end cover. A feeding sleeve is fixedly installed on the upper end cover. A second connecting frame is fixedly installed on the upper end cover. A partition slide rod is slidably installed on the second connecting frame. The partition slide rod is slidably connected to the feeding sleeve. A slide rod is slidably installed on the upper end cover. A spring is installed between the slide rod and the first connecting frame. A rotating gear is rotatably installed on the upper end cover. The rotating gear is in meshing transmission with the slide rod and in meshing transmission with the partition slide rod. A floating rod is fixedly installed on the slide rod.

[0006] Further, a plurality of the first positioning card slots are arranged in a linear array along the rectangular opening.

[0007] Further, a middle-end mold is arranged in the box body and is circumferentially fixed by the contact plate.

[0008] Further, the shape of the middle-end mold is determined according to the shape of the casting to be actually processed.

[0009] Further, an exhaust hole is formed in the upper end cover to balance the air pressure in the middle-end mold.

[0010] Further, the floating rod is made of a high-temperature resistant material.

[0011] Further, as the shape of the middle-end mold changes, the use length of the slide rod should ensure that it can be long enough to enable the two partition slide rods to close the feeding sleeve and cut off the metal liquid flow.

[0012] The advantages of the present invention are as follows:

[0013] During use, first separate the box body and the upper end cover, place the middle mold in the box body, and manually rotate the handwheel. The handwheel drives the threaded rotating rod to rotate, and through the threaded connection between the threaded rotating rod and the sliding plate, the contact plate contacts the middle mold, realizing the circumferential fixation of the middle mold. At the same time, slide the sliding plate along the rectangular opening, and drive the handwheel, threaded rotating rod, and contact plate to move through the sliding plate, thereby changing the contact position between the contact plate and the middle mold and changing the circumferential fixation position of the middle mold, which can adapt to middle molds of different shapes. At the same time, fasten the box body and the upper end cover, so that the positioning rod two and the positioning slot two are re-mated, and inject molten metal into the middle mold through the injection sleeve. When the molten metal is almost full in the middle mold, the floating rod contacts the liquid level of the molten metal, and under the action of the buoyancy of the molten metal, the floating rod drives the sliding rod to move upward. The sliding rod drives the partition sliding rod to move through the rotating gear, so that the partition sliding rod slides relative to the connecting frame two, and the partition sliding rod closes the injection sleeve, cutting off the liquid flow of the molten metal to prevent excessive injection of the liquid flow of the molten metal.
