Description

Technical Field

[0001] This utility model relates to the field of die casting machine technology, and in particular to a die casting machine with a dust removal mechanism. Background Technology

[0002] Die casting is a casting method in which liquid or semi-liquid metal is rapidly injected into the cavity of a die casting mold under high pressure and solidified under pressure to obtain precision castings. In this process, the die casting machine plays a key role in power and control.

[0003] When using the die, install the mold on the die casting machine, ensuring that the mold is installed securely and with appropriate clearance. When closing the mold, ensure that there are no gaps in the closed state. Inject the preheated molten metal into the injection system of the die casting machine, and then apply pressure through the hydraulic system to fully fill the mold cavity with the material.

[0004] During the die casting process, the metal materials used (such as aluminum alloys, zinc alloys, etc.) undergo oxidation reactions in a high-temperature molten state. These metal oxide particles are very fine and remain inside the mold after die casting. For example, during the die casting process of aluminum alloy, a thin film of aluminum oxide forms on its surface. When the casting is demolded, some aluminum oxide particles may fall off and remain inside the mold. These detached metal oxide particles adhere to the surface of the casting, resulting in increased surface roughness and affecting subsequent mold processing. To address this issue, a die casting machine with a dust removal mechanism is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 2This utility model provides an embodiment of a die-casting machine with a dust removal mechanism, including a worktable 1. An electric push rod 6 is fixedly connected above the worktable 1. A movable plate 2 is fixedly connected to the left end of the electric push rod 6. A pressing mold 3 is detachably installed on the inner wall of the movable plate 2. The movement of the electric push rod 6 drives the movable plate 2 and the pressing mold 3 to move, thereby cooperating with the left side above the worktable 1 to complete the pressing operation. This is prior art and will not be explained in detail here. A cleaning mechanism 4 is provided at the top of the pressing mold 3. The cleaning mechanism 4 cleans the inside of the pressing mold 3. The raw material of the cast part after molding is HA1-H to enhance the mechanical properties of the product, thereby achieving the required thrust of the product.

[0034] Reference Figure 3 - Figure 5 The cleaning mechanism 4 includes a support plate 401, with an electric telescopic rod 402 fixedly connected to its inner wall. The support plate 401 provides support for the electric telescopic rod 402. A fixing mechanism 5 is provided at the bottom end of the electric telescopic rod 402, and a cleaning platform 405 is provided at the bottom end of the fixing mechanism 5. The fixing mechanism 5 ensures that the cleaning platform 405 is in a horizontal position, facilitating subsequent disassembly. An air inlet pipe 404 and an air outlet pipe 403 are fixedly connected to the left inner wall of the cleaning platform 405. Exhaust is achieved through the air inlet pipe 404, causing dust to be airborne and discharged through the air outlet pipe 403. The inner wall of the cleaning table 405 is detachably equipped with a cleaning plate 407. The cleaning plate 407 can clean the pressing mold 3 to achieve dust removal. The top of the cleaning table 405 is fixedly connected to a support block 409. The inner wall of the support block 409 is elastically connected to a positioning pin 411 through a connecting spring 410. The support block 409 can provide room for the positioning pin 411 to move. The top of the cleaning table 405 is provided with a connecting component, which can then fix the positioning pin 411. The top of the connecting spring 410 is rotatably connected to a connecting plate 408. The outer wall of the connecting plate 408 is provided with a rubber ball to achieve the purpose of locking.

[0035] Reference Figure 2 - Figure 4The connecting components include a fixed plate 406, the bottom of which is fixedly connected to the top of a cleaning table 405. The cleaning table 405 is concave and provides fixed support for the fixed plate 406. The outer wall of a connecting plate 408 is snapped onto the inner wall of the top of the fixed plate 406. The top of the fixed plate 406 is concave and has a ball hole inside for engaging with a rubber ball. The bottom of a support plate 401 is fixedly connected to the top of a movable plate 2, which provides fixed support for the support plate 401. A cleaning mechanism 4 is also provided on the top left side of the workbench 1. The brush surface of the cleaning plate 407 contacts the inner wall of the pressing mold 3, which cleans the dust from the inner wall of the pressing mold 3. The air inlet pipe 404 also causes the dust to fly. One end of a connecting spring 410 is fixedly connected to a positioning pin 411. On the outer arc surface, the other end of the connecting spring 410 is fixedly connected to the inner wall of the support block 409. The outer wall of the positioning pin 411 is slidably connected to the inner wall of the cleaning table 405 and the support block 409. The elasticity of the connecting spring 410 enables the positioning pin 411 to have the functions of reset and limit. The through-hole setting facilitates manual movement of the positioning pin 411 to release the limit of the positioning pin 411. The top of the cleaning plate 407 has an insertion hole, and the bottom end of the positioning pin 411 is inserted into the inner wall of the insertion hole. The two are inserted to limit and fix the cleaning plate 407. The square surface of the cleaning plate 407 has through holes that match the air inlet pipe 404 and the air outlet pipe 403. A sealing gasket 412 is fixedly connected to the side of the cleaning table 405 facing the pressing mold 3. The setting of the sealing gasket 412 can seal the contact position between the cleaning table 405 and the pressing mold 3.

[0036] Reference Figure 1 - Figure 3 The fixing mechanism 5 includes a positioning plate 501. The top of the cleaning table 405 is fixedly connected to the bottom of the positioning plate 501. The inner wall of the positioning plate 501 is threaded with a bolt 502, which serves as a limiting and fixing mechanism. The side of the bolt 502 near the support plate 401 is threadedly connected to the bottom inner wall of the electric telescopic rod 402. The threaded connection can fix the cleaning table 405 in a horizontal state. The outer wall of the positioning plate 501 is rotatably connected to the lower inner wall of the electric telescopic rod 402. The rotatable setting facilitates the adjustment of the angle of the cleaning table 405 so that it can be easily disassembled when it is in a horizontal state.

[0037] Working principle: When die casting production is required, the electric push rod 6 is activated, extending to the left and pushing the fixedly connected movable plate 2 to move to the left. Since the pressing mold 3 is detachably installed on the inner wall of the movable plate 2, the movable plate 2 drives the pressing mold 3 to move synchronously to the left, cooperating with the corresponding mold or component on the upper left side of the worktable 1 to complete the pressing operation in the die casting process, so that the liquid metal is formed in the mold cavity. This part of the operation is based on existing common die casting technology. After die casting is completed, some metal fragments, dust and other impurities will remain inside the mold. At this time, the cleaning mechanism 4 needs to be activated for cleaning. First, if the cleaning plate 407 needs to be replaced or inspected, the fixing mechanism 5 needs to be operated to loosen the bolt 502 on the positioning plate 501, so that the bolt 502 is disengaged from the bottom inner wall of the electric telescopic rod 402. At this time, the positioning plate 501 can rotate around the rotating connection point with the lower inner wall of the electric telescopic rod 402, thereby adjusting the angle of the cleaning table 405. Rotate to a horizontal position to facilitate the operator's disassembly of the cleaning plate 407. When the cleaning plate 407 needs to be installed, place the cleaning plate 407 into the cleaning table 405, aligning the insertion hole at the top of the cleaning plate 407 with the positioning pin 411. Under the elastic force of the connecting spring 410, the positioning pin 411 inserts into the insertion hole, limiting and fixing the cleaning plate 407 to ensure that it will not shift during operation. After completing the installation of the cleaning plate 407 or confirming that it does not need to be replaced, snap the fixing plate 406 and the connecting plate 408 together to enhance its stability. Then, readjust the cleaning table 405 to a suitable working angle (generally parallel to the inner wall of the pressing mold 3) through the fixing mechanism 5, tighten the bolts 502 to fix the cleaning table 405, start the electric telescopic rod 402, and the electric telescopic rod 402 extends downward, driving the bottom cleaning table 405 to move into the pressing mold 3 until the sealing gasket 412 on one side of the cleaning table 405 contacts the pressing mold 3 to form a seal and prevent dust from escaping.

[0038] Next, gas enters the cleaning table 405 through the air inlet pipe 404. The high-speed airflow impacts the inner wall of the pressing mold 3, causing the dust attached to it to fly up. At the same time, the brush surface of the cleaning plate 407 is in close contact with the inner wall of the pressing mold 3. With the slight vibration of the electric telescopic rod 402 or in the set movement mode, the cleaning plate 407 cleans the inner wall of the pressing mold 3, brushing the dust off the mold surface. The flying dust is driven by the airflow and discharged from the air outlet pipe 403, achieving effective cleaning of the dust inside the pressing mold 3. After cleaning, the electric telescopic rod 402 retracts, driving the cleaning table 405 back to the initial position, waiting for the next cleaning operation after die casting.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
