Description

Technical Field

[0001] The invention relates to the technical field of die casting die frame slag removal, and in particular to an automatic slag removal system for a die casting die frame. Background Art

[0002] The die-casting mold frame can support and fix the mold during die-casting production to ensure that the mold remains stable during the production process, and the mold frame assembles and positions the various parts of the die-casting mold according to the design requirements and is installed on the die-casting machine to ensure the stability and reliability of the mold, because the molten metal will produce oxides when it comes into contact with the air during the smelting, transportation and pouring process. These oxides will form slag, and these slags will remain in the mold cavity and have a ripple effect on the workpiece.

[0003] Referring to the patent CN201922461722.8, a slag removal device for an aluminum alloy die-casting mold is disclosed, which is characterized in that it includes a movable mold frame, an air pipe joint, a slider, a slag accumulation groove, a rubber brush, an airway, a slide groove, and a slag accumulation ball, wherein the movable mold frame is provided with a slide groove; the slider is installed in the slide groove on the movable mold frame; the rubber brush is installed at the bottom of the front end of the slider; the slide groove is provided with a slag accumulation groove; the slag removal device for the aluminum alloy die-casting mold thoroughly removes residues, dust and other debris in the mold, ensures the normal operation of mechanisms such as the slider, thereby ensuring the accuracy level of the parts, and also extends the service life of the mold.

[0004] Based on the search of the above patents and combined with the current slag removal of die casting mold frames, it is found that the existing die casting mold frame slag removal system still has the following two shortcomings:

[0005] First, each pouring operation of the workpiece will produce some slag more or less, but the current slag removal system cannot clean it regularly every time, which will cause some slag to be temporarily stored in the mold cavity, affecting the yield of the workpiece;

[0006] Secondly, when cleaning the residue inside the mold cavity, due to the different shapes of fixed molds of different specifications, the current cleaning device cannot be applied to different mold frames, resulting in low versatility. Summary of the invention

After the cleaning is completed, the telescopic portion of the second electric cylinder drives the base to move backward, so that the base leaves directly above the fixed mold for the next injection molding operation. After each injection, the mold cavity can be cleaned once, which can improve the yield rate. The first dust suction pipe is slidably mounted inside the limiting cylinder, and the vertical end portion of the first dust suction pipe is clamped in the sliding groove on the surface of the placement plate. Before cleaning the residue inside the fixed mold, the worker can move the first dust suction pipe left and right according to the width of the internal groove of the fixed mold, so that the dust suction head at the outer end of the second dust suction pipe can be close to the side wall of the internal groove of the fixed mold, so that fixed molds of different specifications can be cleaned, and two threaded tubes are installed on the surface of the limiting cylinder, and a locking screw is connected to the inside of the threaded tube.

[0051] The first electric cylinder 2 is fixedly mounted on the upper end surface of the fixed frame 102. The end of the telescopic part of the lower end of the first electric cylinder 2 is fixedly mounted with a movable mold 201. The movable mold 201 is located directly above the fixed mold 103. An injection pipe 2011 is mounted on the upper end of the movable mold 201. The telescopic part of the lower end of the first electric cylinder 2 is fixedly connected to the movable mold 201.

After the residue is absorbed, the driving motor 5 drives the driving screw 501 to rotate in the opposite direction. At this time, the lifting plate 8 and the placement plate 7 will move upward together and leave the fixed mold 103.

[0060] Among them, two connecting rods 702 are installed on the upper end surface of the placement plate 7, and the upper ends of the connecting rods 702 are fixedly connected to the lifting plate 8.

Under the action of the suction device, the dust suction head 1101 will generate a strong attraction, thereby absorbing the residue inside the fixed mold 103 to ensure the cleanliness of the inside of the fixed mold 103. The main body of the dust suction head 1101 is inclined, with one part of the dust suction head 1101 opening upward and another part of the dust suction head 1101 opening downward, so the adsorption efficiency of the residue inside the fixed mold 103 can be improved.

[0063] Among them, four threaded holes are opened on the bottom surface of the slot 104, and four threaded holes are opened on the surface of the fixing plate 3. The fixing screws pass through the threaded holes on the surface of the fixing plate 3 and the threaded holes on the surface of the slot 104 in turn to fix the fixing plate 3 in the slot 104. During use, the fixing plate 3 is fixed in the slot 104 by bolts.
